============================================================================ 21.同位语从句只能用that引导(that无实际意义,e.g. The news that he is gay proves…) 22.在GMAT中,复数名词可以拥有单数事物,
e.g. Three out of four own a bicycle. Some have a preferred status over others. 23.rich and poor等同于the rich and the poor 24.type和kind不能等同于事物,要加of P135 8-11 25.While(whereas)一般不引导时间状语从句,而是表示前后的强烈对比,并且要注意前后的搭配(一致),包括单复数和时态. P136 8-12 P144-22;
while + 动词现在分词, 与主句动作做强烈对比 26.Despite后不跟动名词短语,只跟简单名词 27.that和whom所引导的成分为宾语时可省略,e.g. the guy he talked to, the pain it causes, etc. 28.that在其它情况下不能省略! The doctor suggests that… 29.WHAT的用法: A1 is to B1 what A2 is to B2; WHAT的另一种用法what is now P138 8-15 30.当引导从句时, 介词+which优于where, 因为前者更明确 31.理解句意, 注意歧义!
P140-2 avoid duplication of facilities而不是avoid duplicated facilities
避免建设中的重复而不是避免建设;
注意动词和受动词的关系, 注意比较事物之间的关系(什么与什么的比较);
P142-13 a sizeable wolf population有歧义,可能是大型的狼,也可能是大群的狼! 32.当短语或从句中的主语被省略时,一定要看是否和主句的主语相符,
e.g. When sleeping, the hormone is secreted. WRONG! 33.Where once = because P141-5 34.there being错 P141-7 35.after when错 P141-7 36.on condition that后用虚拟语气 P142-12 37.whether引导的宾语从句带有否定或是不确定的意思, 所以从句中可加or not. 如果主句是肯定则不能用whether引导宾语从句 38.P146-27 C选项中没有歧义,可以接受; P144-19 B选项中也不存在歧义, 因为whose不可能修饰blood pressure. 39.There be只能表示在某处存在某事物. 40.在比较中要注意被比较的事物, e.g. P156 9-6中,被比较的是回收纸的数量而不是纸本身,more paper的用法不如the amount o paper准确 41.the more…the more可以省略系动词,但前后要一致: The great the nation wealth, the greater the amount of meat consumed. 42.(至少)等于,或大于的表示: at least as…as; as…as, if not more so; as…as or 比较级 than 43.Goods是复数形式, e.g. Half of his goods were lost in the storm 44.情态动词作用特殊,一般不用其它结构或动词(如be动词)代替. 45.Not any不如直接用no 46.结构上的对称在GMAT中很重要, 尤其在比较中: as…as, more…than 47.Worth prep. 价值 a book worth $20; He is worth $1 million 48.No less an authority than Mr. XXX 象Mr. XXX这样权威的人 49.noun + of + less than是固定用法:
investment of less than $1 million; vehicles of less than 8000 pounds; population of less than 100 people 50.比较中如果前后的主语相同, 后面的主语可省略. P168-13 51.P170-28 No less remarkable than the development of CD has been the use…习惯用法 52.So修饰形容词, such修饰名词,
e.g. such an extraordinary fee或fee are so extraordinary that… so extraordinary fees错! 53.As much as表肯定, so much as用于否定; so much that或as much that错! 54.More (less) of + noun (可数或不可数) 更大(更少)程度上的 P-172-35, less/more为名词 55.Compare to指比喻,比作, e.g. Life is often compared to a voyage;
比较同类事物时用compare with, e.g. compare the brain of human with that of elephant 56.During一般不与将来时段连用, during the next 50 years少用,
多用其它词如over (over the next 50 year), within (within the foreseeable future)等替换
E5-56, E9-55 57.再次强调, 看到代词一定要看是否指代为唯一, 是否会产生歧义! P177-57 58.比较要看事物的可比性, 结构的对称, 59.表示原因一般用because, 较少用due to或since 60.A do (does) sth., just as B do (does) sth.;
Just as A do (does) sth., so B do (does) sth.;
As A do (does) sth., so too do (does) A (or so tooA do (does)
正如…也 As Tom is…so too are we… 61.The nation's three military academics have seen a dramatic rise in applications, one fueled by a resurgence of patriotism, increasing tuition costs at private college, and improved recruiting by the academics. 62.一定要注意主语和谓语的搭配,
e.g. Out of America's fascination with all things antique have grown a market for bygone styles of furniture and fixtures that are bringing back the chaise lounge, the overstuffed sofa, and the claw-footed bathtub.
B. things antique has grown a market for bygone styles of furniture and fixtures that is bringing
E. antique things has grown a market for bygone styles of furniture and fixtures that bring 63.修饰thing一类的词时，形容词放在后面. Things interesting, things antique, 见上例. 64.12. Affording strategic proximity to the Strait of Gibraltar, Morocco was also of interest to the French throughout the first half of the twentieth century because they assumed that if they did not hold it, their grip on Algeria was always insecure.
(A) if they did not hold it, their grip in Algeria was always insecure
(B) without it their grip on Algeria would never be secure
(C) their grip on Algeria was not ever secure if they did not hold it
(D) without that, they could never be secure about their grip on Algeria
(E) never would their grip on Algeria be secure if they did not hold it
这里的角度是French在first half of the century.在那时French did hold it!
虽然与现在的事实相反,如果你改成过去完成时,就改变了原句意思,变成了在first half of the century French没有hold Morocco.
