不定式
1. Leonardo da Vinci was an extraordinary genius, _______ is believed _______ “Renaissance man”.
A. who, to be B. that, to be C. which, to have been D. whom, to have been
【答案解析】 A
【详解】考查定语从句和非谓语动词。句意:列奥纳多·达·芬奇是一位非凡的天才,被认为是“文艺复兴人”。_______ is believed _______ “Renaissance man”是非限制性定语从句,修饰an extraordinary genius,引导词在从句中作主语,指人,应用who引导该从句。sb. be believed to do sth.是固定句式,意为“某人被认为……”。to have done表示该动作发生在谓语动作之前,该题无此意。故选A。
2. Many people feel nervous _______ they attend a concert, so I recommend _______ the hall early to have enough time _______ yourself comfortable.
A. at the first time, arriving, to make B. the first time, to arrive, making
C. for the first time, reaching, making D. the first time, getting to, to make
【答案解析】 D
【详解】考查状语从句和非谓语动词。句意:很多人第一次参加音乐会时感到紧张,所以我推荐你早点到大厅有充足时间让你自己舒服一些。第一个空后面是从句要用连词,the first time引导状语从句。第二个空recommend后面用动名词,第三个空考查有时间做某事have time to do。故选D。
3. We’ve had a good start, but next, more work needs _____to achieve the final success.
A. being done B. do C. to be done D. to do
【答案解析】 C
【详解】考查非谓语动词。句意:我们有一个好的开端,但是下一步需要做更多的工作达到最后的目标。分析句子可知,主语work与do是被动关系,故排除B、D项;need doing或need to be done都表示:需要被做… ,故A项错误,故选D。
4. _________ students develop these social skills, schools in America offer a large number of after-school activities.
A. Helping B. Help C. Helped D. To help
【答案解析】 D
【详解】考查非谓语动词。句意:为了帮助学生发展这些社交技能,美国的学校提供大量的课外活动。根据句意可知此处表示目的,应该用不定式作目的状语,故D项正确。
5. It remains ________ whether herd immunity that most of the Europeans countries have taken in response to the epidemic works.
A. to see B. to be seen C. seeing D. being seen
【答案解析】 B
【详解】考查非谓语动词的被动形式。句意:大多数欧洲国家对流行病已经采取的的群体免疫是否起作用尚待观察。分析句子,并结合句意可知,此处使用remain to do结构,表示有待做的事情,表动作尚未发生,且动词see和主语It之间是被动关系,所以使用动词不定式的被动形式,故选B项。
6. The reporters got to the airport, ______the pop star had gone.
A. only to tell B.
