非谓语动词有三种形式:不定式、动名词和分词,其中动名词不涉及考点,所以重点看不定式和分词(现在分词和过去分词)的考点。

真题检测

真题检测1

A. NO CHANGE

B. oil— to give it (a protective finish) 

C. oil, to give, it (a protective finish)

D. oil to give it (a protective finish)

解析:通过lavender oil to give it看出是不定式作定语的考点,根据不定式作定语无需添加标点符号的规则,排除选项中带有标点符号的选项,所以排除A/B/C三个选项,所以选D。

注:2017-10NA-Q30为2017年10月北美真题30题。

B. information to provide 

C. information; providing

D. information, provides

解析:通过information to provide看出是不定式作定语的考点,根据不定式作定语无需添加标点符号的规则,排除选项中带有标点符号的选项,具体错因为:A和D项需要加连接词,而C项分号后需要前后一致,分号后为分词而非句子,所以排除A/C/D三个选项,所以选B。

注:2017-05AS-Q7为2017年5月亚太真题7题。

真题检测3

A. NO CHANGE

B. the ruling of the court was in favor of Brancusi.

C. the court ruled in favor of Brancusi.

D. Brancusi was the favorable receiver of the court’s ruling.

解析:通过after hearing a lineup看出是现在分词作前置定语的考点,根据在句首的分词要修饰主句主语的规则,排除不能发出hearing动作的主语,即A项的the courts, B项的the ruling和C项的the court,所以排除A/B/C三个选项,所以选D。

注:2018-3AS-Q27为2018年3月亚太真题27题。
