第3课时 Grammar
一、单项选择
1．—If I can have another chance to ________, I will never put off finishing the work.
—OK, I will give you ________ chance.
A．choice, another B．choose, one more C．choose, other
【答案】B
【详解】句意：——如果我能有另一次选择的机会，我永远不会推迟完成这项工作。——好的，我再给你一次机会。
考查动词的用法以及代词辨析。choice选择，名词；choose选择，动词；another另一个；other其他的；one more再一个。动词不定式符号to后加动词原形，排除A；根据“give you...chance”可知是再给一次机会，用one more+名词，表示“再一，又一”。故选B。
2．________ his surprise, many people saw his post online and donated money ________ help the disabled.
A．On, to B．To, from C．At, for D．To, to
【答案】D
【详解】句意：令他惊讶的是，许多人看到他在网上的帖子，纷纷捐款帮助残疾人。
考查介词辨析及不定式。on在……上；to朝，向；from从；at在……；for为了。根据“his surprise”可知，此处是固定短语to one’s surprise“令某人惊讶的是”，第一空用to，第二空是短语donate sth to sb“捐赠某物给某人”，第二空用to，是不定式的符号，故选D。
3．The teenagers are kind enough ________ their help to other people.
A．offer B．offering C．to offer D．offered
【答案】C
【详解】句意：这些青少年很善良，乐于帮助别人。
考查非谓语动词。... enough to do sth.“足够……可以做某事”，此处用动词不定式to offer。故选C。
4．—Would you mind ________ some chocolate
—Sorry, I have made up my mind ________ weight.
A．to have; to lose B．having; losing C．having; to lose D．to have; losing
【答案】C
【详解】句意：——你介意吃些巧克力吗？——抱歉，我已经下定决心要减肥了。
考查非谓语动词。have吃；lose weight减肥；第一空考查短语mind doing sth.“介意做某事”，空格处填入动名词形式，排除A和D；第二空考查短语make up one’s mind to do sth.“下定决心做某事”，空格处填入不定式，故选C。
5．My brother went to the bookstore ________ some books yesterday.
A．buy B．bought C．to buy
【答案】C
【详解】句意：我弟弟昨天去书店买了一些书。
考查非谓语动词。分析句子结构可知，此处填动词不定式作目的状语。故选C。
6．These students volunteer their time ________ the old men.
A．helps B．help C．helped D．to help
【答案】D
【详解】句意：这些学生自愿花时间帮助老人。
考查非谓语动词。volunteer one’s time to do sth.“自愿利用时间做某事”，是固定搭配。故选D。
7．Linda used to ________ in the countryside, but now she is used to ________ in the city.
A．living; live B．live; living C．living; living D．live; live
【答案】B
【详解】句意：Linda以前常住在乡下，但现在她习惯住在城市。
考查动词不定式和动名词。根据“Linda used to...in the countryside”可知，此处表示Linda过去常住在乡下，可用used to do sth.“过去常常做某事”，所以此空应是动词原形live，排除选项A和C；而此处“but now she is used to...in the city”则表示她现在习惯住在城市，可用be used to doing sth.“习惯做某事”，所以此空应是动名词living。故选B。
8．It’s your turn ________ questions.
A．answer B．answering C．answers D．to answer
【答案】D
【详解】句意：轮到你回答问题了。
考查非谓语动词。answer动词原形；answering动名词形式；answers动词单三式；to answer动词不定式。It’s one’s turn to do sth.“轮到某人做某事了”，固定句式。故选D。
9．When will you come to my house I can’t wait ________ you.
A．meet B．met C．to meet D．meeting
【答案】C
【详解】句意：你什么时候来我家？我等不及要见你了。
考查非谓语动词。can’t wait to do sth.意为“迫不及待地做某事”，是固定搭配，故选C。
10．She was ________ on the bridge, because she was afraid ________ into the river.
A．to walk, to fall B．of walking, of falling C．of walking, to fall D．to walk, of falling
【答案】D
【详解】句意：她要走在桥上，因为她怕掉进河里。
考查非谓语动词。第一个空此处使用动词不定式作表语；be afraid of doing sth.表示“害怕做某事”，指担心做某事的后果，故第二个空使用of falling。故选D。
二、用所给单词的正确形式填空
