1. A。考查句型prefer to do sth. rather than do sth.，表示“宁愿……，而不愿……”。句子的意思是 “—这个周末去远足怎么样？—很抱歉，我宁愿呆在家里也不愿意出去”。 2. C。practice的意思是“练习”，其后接动名词形式作宾语，不能接不定式，所以答案为C项。
3. B。pretend的意思是“假装”，其后接不定式作宾语，由此可以排除A和C，其否定形式为pretend not to do sth.，所以答案为B项。句子的意思是“当他走过我的身旁时，他假装没有看见我”。
4. C。分析句子结构可知，该空要使用现在分词作定语，trek的现在分词形式是trekking，所以答案为C项。
5. B。此题考查结构have trouble doing sth.，表示“做某事有困难”，答案为B项。 6. A。be easy to do sth.表示“做某事是容易的”，注意get along with中的介词with不可省，所以答案为A项。
7．B。 句意：彼得在学校忙于工作，但他每天从不忘记做锻炼。be busy doing sth. 忙着做某事；forget to do sth.忘记做某事(事情还未做)。
8．B。 句意：在梦里，我看见一个不明飞行物在广场上着陆。see sb. /sth. do sth．看见某人/某物做某事；land意为“着陆”。
9．A。 句意：汤姆的妈妈让他晚饭后洗碗。ask sb. to do sth. (动词不定式作宾语补足语)让某人做某事。故选A。
10．D。 句意为“——你喜欢弹钢琴吗?——是的，但我不知道怎样才能弹好它”。由句子结构可知，it作play的宾语，所以不能用what。此处考查“特殊疑问词+不定式”，故选D。
11．B。 句意：他制作了一些玩具来讨好他年幼的儿子。这里应该用带to的动词不定式来作目的状语。正确答案为B。
12. D。此题考查句型allow sb. to do sth.，表示“允许某人做某事”，此处使用的是被动语态。
句子的意思是“青少年不应该被允许驾车”。
13. A。tiring “累人的；令人疲倦的，麻烦的；无聊的”，常用来形容物；tired“疲倦的，厌倦的，厌烦的”，常用来形容人。由此可知第一空使用tired。excited意思是“兴奋的，激动的”，多用来修饰人；exciting意思是“使人兴奋的，刺激的，令人惊心动魄的，极其有趣的”，修饰物。由此可知答案为A项。
14. B。此题考查结构spend some time (in) doing sth.，表示“花费时间做事某”，所以答案为B项。
15. C。finish动词，意为“完成”，其后接动名词作宾语，所以答案为C项。
16. C。上句的意思是“你为什么买收音机？”答案为C项，不定式表示目的，也就是说，买收音机的目的是学习英语。
17. D。 let sb. do sth.表示“让某人做某事”，由此可以排除B和C；第一空所填词要作表语，可以使用不定式，但不能使用动词，所以D项正确。
18. B。在短语see sb. do sth.（看见某人做某事）中，动词see后跟不带to的不定式作宾补，改为被动语态时要加上to。所以答案为B项。 II. 用所给动词的适当形式填空。
1. lying 2.going 3.singing 4.eating 5.trying 6. reading 7.laugh 8.not to break 9.to catch 10.to work
