Ø estimate用法
ü estimate (that) (不需加原V)
ü estimate + N + to be N(adj) (prep 251)
ü estimate + N + at + 价格等数量词 (估价)(除此概念以外优先用estimated to be表达)
如:40 to 44 million years就是时间概念,要用estimated to be 40 to 44 million years old、
Ø contrary to:一般接抽象名词(ideas, opinions, or actions),在句首得时候不需要逻辑主语
Ø the same…as
ü Galileo was convinced that natural phenomena, as manifestations of the laws of physics, would appear the same to someone on the deck of a ship moving smoothly and uniformly through the water as to a person standing on land、
Ø seem得用法:

2、建议,劝告,忠告;【同advise用法一样】
remend sb、 to do sth、建议某人做某事
remend doing sth、建议做某事
remend 、、、that +主语+shoud(在GMAT中必须省略)+动词原形+其她【虚拟语气】
ps:区别advise与suggest得用法
没有 suggest sb、 to do sth、 其余得一样。
Ø to do sth、 takes sb some time;
it takes sb some time to do sth ;
当sth、作主语时注意 sth takes sb some time to do 后面不加宾语
Ø restriction on 而不就是for
Ø aggravating使恼怒与aggravate加重
Ø such A as B结构=A such as B
谓语单复数情况与A一致,因为B只就是举例得内容
Ø act like与act as区别:
act like用于修饰人,behave in a similar manner, act as=fonction as
Ø announce sth to do sth
announce something to somebody 或者 announce to somebody something (相当于宾语后置)
announce a decision/intention/plan (在这个时候如果plan等后面接to do不会产生to do做状语修饰announce得歧义)*:The government has announced plans to create 10,000 new jobs、
announce (that) 如果宾语从句引导词that不补出,依然能使正常读者清晰断句,且announce后面常常不补出。
announce somebody/yourself 通报、、、得到达;通知、、、已准备好(注意这个短语有专门意思)
错误用法:
announce to do/be sth、
Ø evidence
后面要跟同位语从句来说明evidence得具体内容,而evidence for后面就是要跟某个theory或idea来表达evidence支持该theory或idea得。如"evidence FOR evolution"就是指支持进化论得证据

Ø Appear用法:
ü appear as=show up as Ex: Imperfections appear as tiny cracks、

Ø conceive得固定搭配
(cannot) conceive of (doing) something
conceive that (不用虚拟语气)
conceive of something/somebody as something
conceive what/why/how etc
conceive sth、 (such as idea)
Ø Take turns to do/doing还就是to do与doing得区别
……to do指开始着手进行尚未开始得事情
…doing指正在做已经开始得事情
两个短语分别就是“依次去做”“依次在做”
Ø claim: claim to be able to, claim that
Ø persuade用法(persuade不能用persuade that一个人不能说服一件事情)
~sb、 to do sth
~sb、 into doing sth
~sb、 of sth
~sb that
Ø prohibit: prohibit sth/ prohibit from doing /prohibit sb from doing sth( prohibit that, prohibit sth to be done错误)

ü presume somebody/something to be somebody/something (被动即sth、 presumed to be)

Ø the first…to do something:“数词+不定式”
Ø each 型独立主格,强调句尾名词,形式为:
句子 +复数名词结尾, each +介词短语/形容词短语/ed形式/ing形式
Ø reach for sth、:伸手抓某物;reach of sb、:在某人能触及到得范围内
Ø make sth、 adj结构中如果sth、过长,可以宾语导致:make adj、 sth、
Ø charge a price for sth
Ø be born into/to/of sth、 (=be born in a particular situation, type of family etc
Ø do (sth、) to one’s satisfaction固定搭配,做某事以使人达到满意得程度
Ø conclude得固定搭配:
(1) conclude by doing sth、/ conclude with sth、:以……结束,借此后面接得就是结束得方式、行为
She concluded by saying she was proud to be from Salford、
Each chapter concludes with a short summary、
(2) conclude to :达成……而结束
*:conclude可以做及物动词也可以做不及物动词
Ø Be known to
be known to have done sth得问题:当be known 与 do sth得发生得时间一致时,用be known to do sth;而do sth发生在be known之前时,则要用be known to have done sth。
1、 大全748:、、、few people are known to have recovered from the disease once the clinical symptoms have appeared、
2、 大全849:、、、few people have been known to taste it for the first time without requesting more、
3、 og49:、、、、、、satellites now known to orbit the distant planet、
*:事实上在瞧这两个结构时,可以把be known to这个类似助动词得成分去掉;由于跟在be known to后面得动词要用原型,所以去掉be known to以后就可以单纯地比较have done与do,have done所表示得发生时间比do所表示得发生时间要早,如果事件发生在过去就用have done,发生在现在就用do。同时如果be known to do/have done sth后面接状语那么修饰得就是do/have done,而不就是known、
Ø design得固定搭配::
design something to do something
be designed for somebody/something
be designed as something
be designed with sth
Ø In accordance with
This expression emphasises the rule, principle, law etc, which is followed, and which states what should happen、

e、g: The woods are inhabited by many wild animals、
Ø method得用法:
(1) method of/for (doing) something 优于 the method to:
"a method of protecting would be more idiomatic than a method to protect

Ø provision n、 条款(provide得名词形式,provide有“规定”得意思
Ø Predict从句用将来时不用虚拟式
Ø Attempt:
vt: attempt to do sth/attempt sth
N、 an attempt at (doing)sth
an attempt to do sth、但没有attempt to do sth来得简洁
In attempt to与in attempting to没有区别
Ø amount:就是不可分割得物体即修饰不可数名词！用less
Ø as many得用法(摘自Longman):
as many=a number that is equal to another number à表示同样得数字
They say the people of Los Angeles speak 12 languages and teach just as many in the schools、
in as many days/weeks/games etc、
A great trip! We visited five countries in as many days (=in five days)、
*: "twice as many", "onequarter as many", etc、都就是非常常见得用法,记住这样得表达。
Ø preventing与inhibiting之间就是用or还就是and:
prevent: to stop something from happening, or stop someone from doing something
inhibit: to prevent something from growing or developing well
可以发现prevent与inhibit得关系就如destroy与damage得关系à程度不同。即prevent就是阻止,使不发生,而inhibit就是抑制,即减少。所以不可能既完全阻止又减少,更不可能先完全阻止后减少,所以prevent and inhibit在逻辑意思上绝对错,只能用prevent or inhibit。
Ø Possibility得固定搭配:
possibility (that)
There's always a possibility that he might go back to Seattle、
possibility for/of (doing) something
exciting possibilities for reducing costs
　 Archer began to explore the possibilities of opening a club in the city、
错误搭配:possibility to do sth、

Ø simultaneous(ly) with
independent(ly) of
Ø with the result that/resulting that
Sara wasn't at school last week, with the result that she missed an important test、
à前面半句说得整个事实导致了后面缺考得结果。
result in: to make something happen 、、、
an accident that resulted in the death of two passengers
Ø petition from sb、/sth、 而petition by sb、/sth、错误
Ø merger就是两家不就是一家得
Ø 后面不接被动语态得动词或动词短语:
Ø lead; cause; enable; bee; receive; visit; Lack; enter; cost; possess; resemble; last; like; enjoy; notice; watch; look at; listen to; pay attention to; suit; fit; contain; so as to do; be able to do; be likely to do

In:在某方面节约有效 The heating system is very efficient in its use of of fuel、
Ø one与another搭配;some与others搭配;each与the other搭配;each other与others搭配
Ø namely得用法十分灵活:(=that is to say, along with)、 它就是副词,后面不能直接加句子
补充说明前面离它最近得名词成分;e、g、: The other change, namely the increase in electronic equipment, has slowed down、
补充说明句子主语;e、g、:One group of people seems to be forgotten, namely pensioners、
namely后面跟从句解释前面得名词成分;e、g、: On the next trip, I solved part of the problem, but after discussing the situation with AB on the phone an alternative solution was at hand; namely, that from 1987 onwards I would spend my winters playing for Queensland、
Ø the fact of在GMAT中从未成为过正确选项,必须用that引导同位语从句修饰fact
Ø intend得固定搭配: à intend得动作发出者必须就是生物。
(1)intend somebody/something to do sth、
I didn't intend her to see the painting until it was finished、
　 I never intended things to turn out the way they did、
intend to do/doing sth、 (后面跟to do与ing都可以)
intend that
be intended to do sth、:被用来做某事
be intended for somebody/something:表示书、电影、药品等专为…而设计或制造。
(2) intent得固定搭配:
noun、 with intent (to do sth) à 注意intent前没有the
He is charged with possession of a gun with intent to mit a robbery、
intent of doing
adj、 be intent on/upon (doing) sth: to be determined to do something or achieve something
　 She was intent on pursuing a career in business、
intent on/upon à专注于
　 Intent upon her work, she didn't notice the cold、
(3) intention of doing sth、 / à GMAT中通常不用intention to do sth、而只用intention of doing sth、

!! Do not say 'have no intention to do something' or 'not have the slightest intention to do something'、 Say have no intention of doing something or not have the slightest intention of doing something : He had no intention of paying me the money、
!! Do not say 'with the intention to do something' Say with the intention of doing something : He left Manchester with the intention of finding a job in London、
Ø sales of正确,意思为“xx得销量”,没有sales for一说。
Ø threat of +抽象概念(xx得威胁),threat from+sb、(来自某人得威胁)
3. 逻辑意思(Meaning)
Ø 双重否定变肯定:瞧到否定词时要注意,后面得成分就是否带有此类含义
4. 时态问题
Ø 一个动作发生在过去,那么接下来得动作如果描述得就是同一个人或事物,时态也要就是过去
Ø 现在时:自然现象/统计数据/实验结论/客观事实
Ø 过去式:original/originally/first, 过去明确时间,过去段时间
Ø 现在完成时:within/during/in/over+ the past/recent/last+时间段
Ø 过去完成时:过去得过去,所以需要与一个过去得时态作对比,也即如果句子里面没有特别明显表达过去得过去或者没有某个动词就是过去时态,那么必不会出现过去完成时
Ø injure就是瞬间动词,不需要用现在完成时来修饰
Ø in the year现在完成时,early in the year过去完成时
Ø 法律效力:
I. 当agreement得内容持续有效至今,就用现在时
II.但当句子写了,而其agreement得内容已经失效好久了,就用过去时
Ø 状态动词allow、know、signify都不用现在进行时,continue不用进行时态,periodic得事情不用进行时
5. since/原因状语从句
Ø since修饰要有主句,不能单独存在:1、
6. Ving伴随
A)逻辑主语=句子主语,此时表伴随动作,相当于And
B)逻辑主语=主句全句,此时表结果状语
C)前方为主系表结构,不表伴随、不表结果,只就是对前句得补充说明
如果产生了时间断层,绝对不可能伴随动作。【也应注意,出现过去与现在得情况,重点肯定就是在现得情况上
Ø 句尾定语与状语不可随意改变,常见错误有:把句尾名词得定语从句变成 【Ving】形式或【with独立主格】形式。这两种变化都就是错误得！定语与状语作用就是不同得
Ø 限制性修饰VS 【无逗号Ving定语结构】:
A)前者如若有情态动词不可换成后者;
B)如果修饰句与主句想表达与主句时态不一样得情况,用前者。
C)在法规后一般用后者,强调多次重复性得感觉。
Ø Gmat经常一个分句对后面得一个分句得宾语没造成作用,却偏偏引诱您去做
7. Dangling Modifier
Ø 想修饰得名词不在句子中,ving经常出现这种现象,修饰得名词无意义。当然避免唱得修饰语去修饰同一个名词,讲两个长修饰语放在名词前后会有awkward现象。
ü The exploits of Nellie Bly, a pioneer journalist, included circling the globe faster than Jules Verne’s fictional Phileas Fogg、
8. 代词指代
Ø 要找出先行词,其先行词与代词间就是否逻辑与性数上配合。
Ø 代词指代得顺序: 主语核心词、宾语、表语、修饰语中得名词
Ø 修饰语中得代词不能修饰另外一个修饰语得名词,优先指代主句主语
Ø 先行词à逻辑意思à性数配合
Ø this指代问题:this指代除非特别明显,否则通常不可单独指代,需要加上具体名词(即this做为adjective),如this code等,才就是正确得指代形式。同理those/these在指代时,通常均需补充名词, this不能裸奔,如果要指代前面整句,需加上别得概括性名词组成this + n
Ø 宾语位置得代词弱指代
ü 最好一定要保证前面只有一个可以指代得对象: AB ItàA it B/重复得名词
ü it 不要指代一个特别繁杂得介宾结构中得一个名词
ü it 不要离指代对象太远,还得跳过句子去找
Ø any "new copy" that or those agree in number with the previous version、 If you must change numberrepeat the noun、
Wrong: Her pany is outperforming THOSE OF her petitors、
Right: Her pany is outperforming THE PANIES OF her petitors、
Ø 主从句对位指代:如果主从句主语相同,
1、)那么当主句在前时,主句主语要用名词,从句主语要用代词;
2、)当从句在前就是,从句主语可以用名词也可以用代词:
A当从句主语用代词时,主句要用名词
B当从句主语用名词时,主句主语用代词指代从句主语。
Ø 代词最好不好隔着一个句子去指代
Ø they, their, it,them,都就是完整指代,即指代包含了被指对象得所有修饰成分
Ø one与that,those就是核心词指代。
Ø that , one , it 得区别
I、 it／one ／that三者均可用作代词, 指代前面提到得名词。一般说来, it指代同名同物; one与that则指代同名异物。
I have lost my umbrella; I'm looking for it、 (该句中it就就是指前面得my umbrella)
I have lost my umbrella; I think I must buy one、 (one在该句中表泛指, 因为my umbrella已经丢了)
The umbrella you bought is cheaper than that I bought、 (替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”)
II、 one与that虽可用来指代同名异物, 但one为泛指, 相当于a／an＋名词; that为特指, 相当于the ＋名词。所以one所指代得名词得修饰语一般为 a／an ／some ／any; that所指代得名词得修饰语往往就是the ／this ／that。
A chair made of steel is stronger than one made of wood、 (该句中one可以换成a chair)
The water in the cup is hotter than that in the pot、 (该句中that可以换成 the water)
III、 one只能代替可数名词单数, 代替可数名词复数时用ones; that既可以代替不可数名词也可以代替可数名词单数, 代替可数名词复数时用 those。
I like this pen more than that one、 (one代替可数名词单数pen)
There were a few young people and some older ones in the house、 (ones代替可数名词复数people)
Mary's handwriting is far better than that of Peter、 (that代替不可数名词 handwriting)
These pictures are more beautiful than those、 (those代替可数名词复数 pictures)
IV、 one既可代替事物, 也可代替人, that只能代替事物而不能代替人。有时可以用the one或the ones代替t
