高频语法选择部分
The lower______in a room, the more slowly our eyes focus.
A-the level of lighting B-light level C-leveling of light D-lighting is level
=if the level of lighting is lower in a room,our eyes focus more slowly
compare: light vs lighting
light is a concrete concept, which you can see, touch and feel. Lighting is rather abstract, a notion/idea formed in your mind. So the former we translate into 日光，灯光，光线，灯。。。, while the latter we take as 照明。So, there is no such kind of thing called "light level", but only "the level of lighting"
If you want to read more about
"the more...the more" structure, please refer the following address:
http://bbs.taisha.org/viewthread ... ge=1&highlight=
14. Experiments related to the sense of smell are more easily _____ than those related to perception of color.
(A) setting them up (B) to set up (C) set up (D) sets up those
This is simply a passive voice.
...are (more easily) set up than...
many guys mixed it up with the fixed phrase: be easy to do sth
13. Fossils, traces of dead organisms found in the rocks of Earth's crust, reveal --- at the time the rocks were formed.
(A) what was like (B) was like life (C) what life was like (D) life was like
here "what" leads an object clause. reveal is a vt, what acts as the object of "like"
life was like (what) at the time (that) the rock were formed
The Texas Legislature selected Vassar Miller________in 1982, and again in 1988.
A. was the state's poet laureate B. as the state's poet laureate
C. the state's poet laureate D. become the state's poet laureate
This question is rather disputable here.
In my understanding, B is the only correct answer.
select sb as sth
as I finally find an example in the collins dictionary:
He used his influence to make sure she was not selected as a parlianemtary candidate.
The distinguishing feature of a fluid, in contrast to a solid, is the ease_________.
A. that a defored fluid B. to deform a fluid
C. when a fluid that is deformed D. with which a fluid may be deformed
A is not an attributive clause
B: wrong prep.
11. ____over 100 years since the invention of the square-bottomed paper bag.
(A) Now is (B) Now it has (C) There is now (D) It is now
1．It可以表示时间，天气等等（比如it is Tuesday. It is cloudy,等等），这里就是表示时间而已，不是形式主语。
2．这个是个很简单的句式：
it has been+时间 since。。。或者it is +时间 since。。。
12．At its center, the sun has a density of over a hundred times __ and a temperature of 10 to 20 million degrees centigrade.
(A) that of water (B) of water (C) than that of water (D) water
the original form is:
...times the +noun+of+...
here "that=the density". The reason for that is simply to avoid repitition of same words.
so the sentence can be read as:
At its center, the sun has a density of over a hundred times the density(=that) of water and a temperature of 10 to 20 million degrees centigrade.
7）living organisms contain more water____substance.
A) than do any other B)does than any other C) other tahn do any other D) than they do any other
the sentence can be read as:
Living organisms contain more water than living organisms (=they) contain (=do) any other substance.
many guys mischose A as the correct answer.
there are at least two mistakes in item A:
1 grammatically, here "substance" is uncountable. so at least "do" should be changed to "does"
2 logically, it is wrong.
(A) living and working (B) they live and work
(C) live and work (D) to live and to work
This is an attributive clause, omit "that"/"in which" here, and modify "the way"
the clause can be read as:
the way (in which/that) people in the US live and work
Connecticut was the fifth of the original thirteen states _____the Constitution of the United States.
A-ratified B-ratify C-to ratify D-have ratified
it should be: Connecticut是13个里第五个批准了美国宪法。
A is not correct here, since it at least should be "raditied BY".
3.All eels spawn in the sea, the eggs hatching into transparent,ribbonlike larvae ___,feeding until they metamorphose into small eels.
a.that dfrift about b.drift about
c.about drifting d.drift about them
this is an attributive clause, modifying "ribbonlike larvae". "about" here is an adv, meaning "everywhere"
1.By focusing on the interesting,_____the significant,the penny press newspapers of the 1830'helped to changde the concept of news.
a. which does not necessarily b.not necessarily
c.was not necessarily d.nor necessarily being
here is the structure of "focusing on A not B", necessarily is only a modifier.
(A) steel it can (B) can steel (C) with steel can (D) so can steel
as here means "In the same manner or way that", it's a conj
after as, the clause can be reversed.
(A)as on (B)because (C)the way that (D)similarly
sculpture ON some coins
(A) making (B) to make (C) are made (D) have made
nothing special with this question, but most ones are confused by "be"
this is simply a typo, it should be "BY"
(A) won (B) winner of (C) to win (D) who the winner of
这个涉及到冠词的省略：
1表示官职，身份，头衔的名词
2专有名词做同位语（这题就属于这个）
3做不完全动词的补语
还有其他大约七八种也不加冠词，比如病名，学科，等等
(A) which as the sum of (B) of the sum which
(C) whose sum of whose (D) whose sum that the
the question has been argued for quite a long time.
My understanding is A is the only correct one.
The sentence can be read as:
In geometry,.... all points, which , as the sum of distances from two fixed points, is constant.
which=the locus of all points
some guys think C is correct. I don't agree with this.
How can an attributive clause have two relative prons (whose), since there is only one antecedent?
ps. There is another understanding that C should be "the sum of whose"
Then I think C is better than A.
(A) that of understanding (B) to have understanding
(C) the understanding (D) understanding that
here is a simple sentence, no clause here in this sentence.
"that" here is a pron and not relative pron, referring "the area"
3.Fibers of hair and wool are not continuous and must normally be spun into thread____woven into textile fabrics.
a.as are they b.when to be c.that they are d.if they are to be
D is definitely correct.
But most guys can not tell difference from B to D
B is not suitable here in this sentence. If you choose B, the logical subject of "to be woven" is "thread" and NOT "fibers".
Only is there no misinterpretations, the subject or even the predicate can be omitted.
(A) The extension of (B) The extension (C) Extending (D) Extends
well, I am really surprised that so many guys have problem with this question.
and soooooooooooo many think the answer should be A!!
and soooooooooooo many take A as the appositive of "the Eric Canal"!!
well, what is an appositive? If we say A is the appositive of B, then we can conclude that: A=B
Can the Eric Canal=The extension?????????????运河=扩张？？？？？？
absolutely NOT.
so A is definitely wrong.
A dedicated to raising B dedicated raising C dedicates to raise D that dedicates to raising
here are two grammar points:
1 an annual international event (which is) dedicated to raising, passive voice
or we can take it as "past participle expressing passive voice, acting as a postponed adj
2 be dedicated to sth/doing sth(gerund), to here is a prep.
the original phrase is: (a person) dedicate sth to sth/doing sth
A. what B. which C. there is D. where
1 This is a subject clause
2 remain is a vt
from the above two, we can find only A is correct, since what=the things that
A. make up that now B. make up now that
C. that make up now D. that now make up
lack an attributive clause, so only D is correct
another problem is "now". Some guys ask about why C is NOT correct, since they think "now Canada=Canada nowadays".
1 remember now can NEVER be an adj. so here "now" can NOT modify "Canada".
2 频度副词的位置简单记法：A 没有助动词，就在实义动词之前 (I OFTEN go there.)
B 有助动词： 助动词＋频度副词＋实义动词 ( I have NEVER been there.)
C 有两个以上助动词：助动词1＋频度副词＋助动词2（通常是BE）＋实义动词 (The book has ALREADY been taken away.)
D BE做实义动词：BE＋频度副词 (He is ALREADY here!)
A. so then breaks B. when breaks it
C. which then breaks D. for which then breaks
the sentence means:
To break thick ice, the icebreaker boat needs to do the following:
1 the icebreaker boat moves fast
2 then the icebreaker boat rides up on the ice
3 then the ice breaks under its weight.
A. whose presence B. which is present C. presenting D. in the presence of which
this is simply an attributive clause, only need to make the structure clear.
carbon dioxide and water react to form carbohydrates in the presence of chlorophyll(=which)
A.to base democracy B.for democracy to be based
C.democracy be based D.whenever democracy is based
this is subjunctive mood
insist that...(should) do... should is often omitted in American English
similar verbs in subjunctive mood: V+that...(should)+do
advise, direct, ropose, advocate, dictate, prefer, agree, expect, pray, appoint, insist, provide, arrange, intend, request, argue, legislate,recommend, ask, maintain, require, command, suggest, permit, object, order, demand
高频语法改错部分
The Van de Graaff generator, an electrostatic machine(A) used of(B) nuclear physics to study (C)transformations in subatomic particles, produces (D)powerful electric currents.
of---------------in
39 The oriental fruit fly causes extensive (A)damage to grapefruit,lemons,and oranges bur does not(B) harm to trees on which(C) the fruit grows(D).
does not------------does no
does here is a content verb and not auxiliary verb
harm here is a noun, so some degree adj.s can modify "harm" as in the phrase " do harm to":
do no harm to
do little harm to
do a little harm to
do great harm to
...
harm can also act as a verb. When it is a verb, it is a vt.
so "harm sth"
36.(One of the problems) of United States agriculture that has persisted (during the) 1920's until the present day is the tendency of farm income to lag (behind) the costs of (production).
during the--------from the
here is the phrase: from A until B
37 Composer Richard Rodgers and lyricist Oscar brought to the musical Oklahoma! extensive musical and theatrical backgrounds as well as familiar with the traditional forms of operetta and musical comedy.
familiar---------familarity
bring A to B
here A=extensive usical and theatrical backgrounds as well as failarity with the traditional forms of operetta and musical comedy , which is TOOOOOOOOO LONG! So B is postponed as in this sentence: bring to B A
the short for this is:
brought ...backgrounds and (=as well as) familarity with...
so familar should be in its noun form, since it is the object of "bring"
40. Collagen, a （strong） rubbery protein, （supports ）the ear flaps and the tip （of nose） in （humans）.
of nose---------of the nose
nouns in their singular forms USUALLY can not exist without articles.
32. Female sea turtles, before laying her （A）eggs, swim as much as（B） 2,000 kilometers to return （C）to the beaches where（D） they themselves were hatched.
her-------their
Guys have problems with B, as much as.
2000kilometers is taken as a distance, so "much" is used here.
24.Dolphins are sleek and (powerful) swimmers （that found） in all seas and unlike porpoises, （have ）well-defined beaklike snouts and conical (teeth).
that found--------1 found/ 2 that are found
1 is past participle as a postponed modifier
2 is an attributive clause
both indicate passive voice
Nothing wrong with "C have", the structure of the sentence is:
Dolphins are...and have...
35. （At first） the poems of E.E. Cummings gained notoriety （to） their idiosyncratic punctuation and typography, but they have （gradually been） recognized for（ their） lyric power as well.
to-----------for
something about "fame", the prep is "FOR", such as "be famous FOR"，由于。。。而获得怎样的名声
In the early 1900s, Roy Harris created (and promoted)(A) a (distinctly)(B) American (style)(C) of classical music and greatly influenced a number of (composer)(D) in the US.
composer----------composers
most guys here ask about "distinctly"
here "American" is an adj. "distinctly" modifies "American" and NOT "style"
39. (Generally), Abstract Expressionist art is without recognizable images (and does) not (adhere the) Limits of conventional (form.)
adhere the--------adhere to the
adhere is an vi.
here is a discussion of "form"
is "form" countable or uncountable?
form can be both countable and uncountable.
in this question, form is uncountable.
I think here are two ideas:
one is "art form", as 艺术形式,I don't think it is countable. This is very abstract.
the other is "a form of art", as（某）一种艺术形式, so it is countable. This is concrete.
compare:
metaphor
When you take it as a figure of English speech or English rhetorical form, it is uncountable.
But if you refer it to concrete examples, it is countable.
e.g.
A general type of description of metaphor ofen seems to be the only level at which theorists and researchers of different persuasions can agree, with similar "definitions" found in many key publications.（概念名词，不可数而且无定冠词）
A further way in which metaphors in discourse often deviate from the typical examples is in the absence of explicity stated Topic terms.（这里是指discourse中人们所用的具体的metaphors，所以用复数）
19．(Early) signs (characteristic) of the acute phase of viral hepatitis in (adults) are abdominal pain, nausea, and (feverish) often accompanied by chills.
characteristic here is an adj and not noun.
it is postponed as in the phrase "characteristic of...", modifying 'signs"
here is another example of postponed adjective:
e.g.
He is a capable man.
He is a man capable of speaking several foreign langauges.
26 (Among) the symptoms of measles, which takes about twelve days (to) incubate, (are) a high fever, swelling of glands in the neck, a cough, and (sensitive) to light.
sensitive------------sensitivity
the sentence is reversed, since it begins with an adverbial phrase "among the symptoms of measles"
the sentence subject is "a high fever, swelling of ...and sensitivity to light"
the normal order of the sentence should be:
A high fever,... and sensitivity to light are among the symptoms of measles, which takes... to incubate.
cell----------cells
each of the pl.
16. The developed (coutries) of the world are (using up) valuable (resources) at a rate (unprecedented human) history.
unprecedented human-----------unprecedented in human
this is rather confusing to many guys, because the adj "unprecedented" is postponed.
the sentence actually is:
...at an unprecedented rate in human history
28. An activist for women's rights, Leonora O'Reilly promoted women's vocational training (besides) fought for increased wages for garment workers.
besides-------------and
besides can not act as a conj.
here: promoted ...AND fought...
25. Rocks (form) within Earth are called intrusive or plutonic rocks (because the) magma (from which) they form often intrudes into (neighboring) rock.
form------------formed
here form is a verb, in its past participle form, acting as a postponed modifier.
the sentence can be read as:
Rocks (which are) formed within...
many guys here have problems with the last word "rock"
rock can be both countable and uncountable. 如果是指这种material，通常是不可数的；如果是指a piece of rock,那么是可数的。
29. The (modern) violin, the smallest (and versatile) instrument in the violin family, is (tuned) in fifths and produces tones (ranging) over four and a half octaves.
and versatile-------------and the most versatile
If you understand this as最小的多功能乐器, it should be: "the smallest versatile instrument" without "and"
26.(Because) it is often dependent of the conditions (of) crytallization, the composition of the( minerals )in a rock can be important ( in determing ) the rock's geologic history.
dependent of-----------dependent on
32. Fats and fixed oils are greasy ( or ) waxy ( substance ) that ill ( their) pure state are (normally) tasteless, colorless,and odorless.
substance--------substances
ill----in, a typo
(With more than) half the world's (annual yield of) 50 million tons of soy beans , an (important source) of protein, is (grown in ) the United States.
With more than--------More than
If with is here, the sentence appears without the subject.
an important source of protein is the appositive of more than ... beans
Art Deed, (a style)of (design popular) in the 1920's and1930's, was used primarily in furniture, (jewel),(textiles), and interior decoration.
jewel---------jewels/jewelry
This one is disputable here as well. My understanding is: jewel is countable, so one correction is make it as a pl noun. That is: jewel.
second one is to make it as a collection, that is "jewelry"
Paleoanthropologists examine fossil (remains)of extinct primates, while physical anthropologists (concern) with ethology study the behavior of primates (in) their (natural settings).
concern--------concerned
guys have problem using "conern"
once more here:
1 sth concern sb.
2 sb is concerned with sth
concern is similar to "worry"
31Statistics (indicate) that (approximate) every 22 years--within a range of 3 to 4 years--a major drought occurs in the United States.
approximate-------------approximately
here nothing wrong with "indicate"
statistics is the pl form of statistc here, meaning 数字统计
39. (By) 1810 the 23 towns of Hampshire County, Massachusetts, (had reached) a remarkable (uniform) of economic development (as well as) population density.
uniform----------uniformity
the question is disputable. Personally I think the wrong part is "uniform", since if "uniform" is a noun, it means制服。In this sentence, it should be 一致,which is "uniformity".
28. Not much (is it) known about the details of the (development) and the acquisition of primate (communication), especially (in the wild).
A
is it-------------------is
the sentence subject is not much, so it is not necessary here.
there is nothing wrong with D.
the wild=the wild area
e.g.
the rich=the rich people
the young=the young people
the old=the old people
the poor=the poor people
it normally unsuited-------------it is normally unsuited
unsuited is an adj.
of mineral----------of a mineral
mineral is countable here.
than was--------------was
here is "the more...the more..." structure, so "than" is not needed.
the farther...the smaller...
Unique (among) bibvalves, scallops swim extremely (well) , propelled by jets of water expelled while (snapped) the shell (shut).
snapped--------snapping
among未必表示最高级。She is among us，根本就不存在最高级。何况这里among之前还有unique提醒你，只是表示扇贝的游泳在bibvalves里是独一无二的，并没有说它是最怎样的。这里是主被动的关系搞错了，是扇贝去snap它的shell，shut是shell的宾补
When (study) different cultures and societies , anthropologists often (focus) on marriage as (a) contractual agreement between (different parties). 答案A，要改为 they study 还是 studied ???
逻辑主语是anthropologists，主动study，用现在分词表主动。
the sentence can be read as:
when (anthrophlogists) study...
concerns------------deals/
concern is a vt. the usage of "concern":
1 sth concern sb
2 sb is concerned with sth
Usually an atom (having) one , two , or three electrons in (its) valence band readily contributes electrons to and (receive) electrons from (neighboring) atoms.
receive------------receives
lots of guys ask about this question here.
actually if you are more careful, you will find the problem yourself.
it is a simple third singular person problem.
celebrating------------celebrated
celebrated: =well-known/famous
library-------------libraries
lot of guys here ask about what is "that" in B
that=the art-related reference and research library
sentence can be rewritten as:
The ar-related and research library(=that) of the Metropolitan Museum of a Art in New York City is among the largest and most complete libraries of all the art-related reference and research libraries in North America.
how--------------when
the clause can be read as:
when vibrations (transmitted=which are transmitted后置定语 through the air) strike (predicate) the eardrum
its------------their
guys here ask about A--------faced with, here are some explanations:
face sth
face sb with sth/face sth with sth
If here is without "with", then "faced" should be changed to "facing"
interesting-------------interest
it is a very common phrase in English:
be+adj=be+of+noun
to benifit---------------to the benifit
live large--------------live in large
here are two questions most guys ask about:
1 The Hopi, the tribe, here both emphasize people, so nothing wrong with "have"
2 live is usually an vi, so should "live IN" someplace.
3 live sometimes can be a vt, when its object is its paronym, like "life"
but----------and/but not
most guys are confused with "chemicals"
第一chemical可以做名词，是化学制剂；其次，化学制剂可以是major economic activities. chemistry是不对的，因为chemistry是一个学科.
planets other----------other planets
most guys have problems with "in orbit", since no article appears before "orbit"
well, "in orbit" is a fixed phrase, which means "travelling in this kind of path"
considerably------------considerable
here considerable modifies "abilities"
problem-solving is an adj here, problem-sovling abilities can be taken as a whole part.
and "the higher animals", in my understanding, is 高级动物
gamble----------gambling
gamble是可以做名词，但意思是冒险，而且是可数名词。gambling是个抽象名词，指'赌博'这个action
unique-----------uniquely
many guys take "American" here as a noun. "American" here is, actually, an ADJ.
so ADV. modifies ADJ.
If American is a noun, meaning American people, it should be in its pl form, which is "Americans"
so if you want to change "unique" to "unique to", it should be " unique to AmericanS"
mass-----------masses
singular countable nouns normally can not appear without articles
it-------------them
guys have no problem understanding why D is not correct.
but the problem is "the carbon-are", what the hell is " are" here?
it is a typo! it should be "arc" . both "are" should be "arc"
The carbon-arc lamp:炭弧灯，a kind of lamp
is very little atmosphere.
visibly-----------visible
the logical subject of "visible" is "Pluto"
so Pluto is visible.
the sentence can be read as:
when Pluto is visible only through..., it has a...
resisting-----------resistant
for complexity------------for the complexity
icomplexity has a postponed modifier "of a space mission", so it should be identified.
moisture-----------moist
here moist means humid
have made----------have been made
this is very simple, only a passive voice needed here.
guys here ask about C, notably.
can notably modify noun? since it is an adv.
well, in English, there are a special group of adv.s which can modify nouns. They are:
also, especially, even,approximately, exactly, hardly, just, mearly, not, particularly, notably, precisely, quite, scarcely, simply, solely, too, etc.
rich-----------richer
richer...than
plan-----------plans
singluar nouns can not appear without articles.
The main clause is: The first city was Washington,D.C.
greatly------------very/too
greatly usually modifies VERBS.
of functions---------------function/of the functions
features-------feature
since the verb is "is", so feature should be singular.
the most distinctive feature=one of the most important reasons
so the predicate is singular.
mature plant----------mature plants
Guys have problems with B, which seems very 别扭 to most guys.
But actually nothing wrong with B. It is subject complement.
like "open" in "The box fell open". "mad" in "The guy went mad".
gatherings, and (other such) activities.
essential-------essentially
essentially modifies the whole sentence.
chemical-------chemically
here chemically modifies active and not form or oxygen.
* concern
1 sth concern sb.
2 sb is concerned with sth
concern is similar to "worry"
* form
is "form" countable or uncountable?
form can be both countable and uncountable.
in this question, form is uncountable.
I think here are two ideas:
one is "art form", as 艺术形式,I don't think it is countable. This is very abstract.
the other is "a form of art", as（某）一种艺术形式, so it is countable. This is concrete.
compare:
metaphor
When you take it as a figure of English speech or English rhetorical form, it is uncountable.
But if you refer it to concrete examples, it is countable.
e.g.
A general type of description of metaphor ofen seems to be the only level at which theorists and researchers of different persuasions can agree, with similar "definitions" found in many key publications.（概念名词，不可数而且无定冠词）
A further way in which metaphors in discourse often deviate from the typical examples is in the absence of explicity stated Topic terms.（这里是指discourse中人们所用的具体的metaphors，所以用复数）
* some
some有两个基本含义：1一些；2某个某些
ETS考到的永远是第二个意思。其实some的这个意思大家很早就接触到了，只是没有在意而已——some one, somebody, something, sometime, sometimes...
tips:学习一定要"知其然知其所以然"，不要忽略简单的每天发生的事物。——你看见，不代表你知道。
*名词和动名词的差别
garden vs gardening; light vs lighting...
有些名词，本身是名词，但是仍然可以加上ing变成另一个名词。两个之间的差别是：前者是可看得见摸得着的具体事物，而后者则是将前者提高到抽象的concept。
比如garden是花园-----------gardening是园艺（技术）
light是光线，日光，灯光，灯--------------lighting是照明
* 频度副词的位置简单记法：
A 没有助动词，就在实义动词之前 (I OFTEN go there.)
B 有助动词： 助动词＋频度副词＋实义动词 ( I have NEVER been there.)
C 有两个以上助动词：助动词1＋频度副词＋助动词2（通常是BE）＋实义动词 (The book has ALREADY been taken away.)
D BE做实义动词：BE＋频度副词 (He is ALREADY here!)
