GMAT一个常见的错误就是把一个完整的概念用一个名词来代替,造成对概念的解释不完整或引 起结构的复杂.
这种错误常出现在宾语从句和that引导的同位语从句中: that引导同位语: Scientists find a result that rats will demonstrate some interesting behaviors.
用名词来代替会变成:
Scientist find a result of rats that will demonstrate some interesting behaviors. (解释不完全) 或Scientist find a result of rats as demonstrating some interesting behaviors.(结构笨拙,复杂) 宾语从句: …revealed that creatures of the seabed were suffering because food supplies were dwindling… 用名词来代替: …revealed creatures of the seabed that…(解释不完全) …revealed creatures of the seabed’s suffering…(结构笨拙,复杂) 解决这两种问题的方法就是用 that 从句引导句子,简化结构,并能够进行完整的解释 1)
能用动词表达的,就尽量不要用动名词和形容词来表达 2)
限定性从句和非限定性从句:
限定性定语从句对先行词起限制、确定作用,与先行词有着不可分 割的联系,它的前面通常没有逗号;非限定性定语从句与它的先行词之间只有比较松散的关系,通常 用逗号将它与主句隔开 4) being的错误使用:
以下几种表达中being属于多余 a) being + n. b) being + adj. c) as being + n./adj./v-ing 3)and在连接句子时,只能连接并列的独立句子(即主句),and后面的句子不能与从句并列。 2)
替代原则:
前面出现过的动词,后面只能用do和did代替,或者重复前面出现过的动词. 1)
习惯用法:表达速度是多少时习惯用speeds of… significant
和 significantly 的区别:前者意思较广泛,有意义重大,重要等意思,而后者则意思明确,只 表示程度很深的意思 2)
逗号+ -ed形容词的结构中, -ed形容词从语法上修饰的是逗号前最后一个名词 1)
现在分词的完成时态不能作定语修饰名词:
如
evidence having been proved…是错误的,可以 改为 evidence proved…
或evidence that have been proved… 2) be able to do和can的区别:
前者表示拥有某种能力去做某事,强调的是能力;后者表示可能去做 某事,表现了一种可能性 1) one和ones指代前面出现的单数和复数名词的核心词,
例:The proposed urban development zones represent not a new principle, but one that was employed in “Operation Bootstrap” in Puerto Rico.
其中one指代前面出现的单数名词核心词principle而不是a new principle |
