GMAT语法,又叫句子改错(sentence correction),是整个GMAT语文(VERBAL)三大题型中难度最高却也最容易提分的题型。说它难度高,是因为英语语法向来是中国考生的软肋,特别是对于英语基础不扎实的考生来说可谓老大难问题。至于提分容易,则是因为比起出题思路天马行空、文章难度高深莫测且基本没有规律可循的阅读和逻辑来说,GMAT语法无论是考点还是难度,都更有规律,花费同样时间精力复习往往提升更为明显。如果考生们还想更多了解别的语法点,请点这里!
话虽如此,想要考好GMAT语法秒解难题还是需要花上一番功夫的。特别是对于考试涉及的各类语法点和疑难杂症,考生势必要多加努力才能有所收获。下面小编就为大家汇总整理了GMAT语法考试中出现频率最高也最容易做错的语法难题,配合实例解析,为大家每日讲解。
GMAT语法大百科每日语法点:不定式加完成时的用法说明
第一个用法,也就是在GMAT中常出现的,信息提供的人不是直接的陈述者
如human beings are thought to have first entered the Americans
human beings first entered这个观点不是这篇文章的作者这么想,而是 are thought(被认为 – 被人们认为)
因为to have 是用在indirect speech,所以经常跟在think, claim, believe 等于陈述信息相关的单词后面多以被动的形式出现. To 前面动词的事态没有限制
第二种用法是future
如he is to have become the next president by the end of January
- he will have become the next 与这个意思想象,不过 will 是uncertain is to have 是certain
he was to have been next president (在过去的时点上看未来)
GMAT不定式加完成时用法实例讲解
Balzac drank more than fifty cups of coffee a day and died of caffeine poisoning; furthermore, caffeine did not seem to bother Samuel Johnson, the great writer and lexicographer, who was reported to have drunk twenty-five cups of tea at one sitting.
(A) furthermore, caffeine did not seem to bother
(B) however, caffeine did not seem to bother
(C) however, caffeine did not seem to have bothered
(D) furthermore, caffeine did not seem to have bothered
(E) in addition, caffeine did not seem to bother
选项分析:
做这个题的时候有些考生可能看到没有划线部分的have drunk 后根据平行原则选C, 但这里因为seem 不是表达别人意见的词,而是做着对这件事情的看法,所以就没有必要用to have bothered
所以 正确 答案是B.
