A．not to spend B．to not spend C．don’t spend D．not spend 【答案】A 【详解】句意：我的父母经常告诉我不要花太多时间玩电脑游戏。这对我的眼睛和学习都不好。 考查动词不定式的用法。根据“tell”可知后面用动词不定式，“tell sb. to do sth.”意为“告诉某人做某事”，根据“It’s bad for my eyes and study.”可知是告诉不要做，否定形式为“tell sb. not to do sth.”，选项A的“not to spend”符合题意。故选A。 2．It’s necessary for us ________ English well because it’s an international language. A．learn B．to learn C．learning D．learned 【答案】B 【详解】句意：对我们来说学好英语很有必要，因为它是一门国际语言。 考查非谓语动词。固定句式“It’s+形容词+for sb. to do sth.”意为“对于某人来说做某事是……的”，其中“it”是形式主语，真正主语是后面的动词不定式“to do sth.”。此处需用“to learn”作真正主语，故选B。 3．After a long rest, I was ready ________ my homework. A．to do B．do C．doing D．did 【答案】A 【详解】句意：经过长时间的休息后，我准备做我的家庭作业了。 考查非谓语动词。be ready to do sth.是固定短语，意为“准备做某事”，其中to do是不定式作状语，表示目的。故选A。 4．Do you have free time? I’d like to invite you ________ Mount Tai. A．climbing B．climb C．climbed D．to climb 【答案】D 【详解】句意：你有空闲时间吗？我想邀请你去爬泰山。 考查非谓语动词。invite sb. to do sth.“邀请某人做某事”，是固定搭配。故选D。 5．—Lily, what did Mr. Han say just now? —He told us ________ too much noise. A．to make B．make C．not make D．not to make 【答案】D 【详解】句意：——莉莉，韩先生刚才说了什么？——他告诉我们不要制造太多噪音。 考查动词不定式的否定形式。根据语境可知，此处是韩先生告诉莉莉等人不要制造太多噪音，tell sb. (not) to do sth为固定搭配，意为“告诉某人（不要）做某事”，因此应该用not to make。故选D。 6．As soon as the school bell rings, the kids can’t wait ________ out to play football on the playground. A．going B．go C．to go D．went 【答案】C 【详解】句意：学校铃声一响，孩子们就迫不及待地出去到操场上踢足球。 考查非谓语动词。going动名词/现在分词；go动词原形；to go动词不定式；went动词过去式。根据固定短语“can’t wait to do sth.”可知，此处需填动词不定式。故选C。 7．Qiqi hopes ________ medicine in Sichuan University.

But we need ________ a table on the telephone first. A．book B．booking C．to book D．to booking 【答案】C 【详解】句意：——今晚去重庆饭店吃晚饭怎么样？ ——好主意。但我们需要先打电话订个座位。 考查非谓语动词。book“预定”，动词；need作情态动词时，后接动词原形，但这种用法更常见于否定句或疑问句，在肯定句中极少使用，题干中“we need...”是肯定句，因此排除“need +动词原形 (book)”的选项A；need作实义动词时，常用结构need to do sth.“需要做某事”，这里表示“我们需要先通过电话预订一张桌子”，是主动去做预订这个动作，所以用“to book”，排除D；而need doing则表示“某物需要被……”，其本质是主动形式表被动含义，题干中主语是 “we”(人)，且动作主动，不符合“need doing”的用法场景，因此“booking”(选项B) 排除。综上，故选C。 9．The students were asked ________ some interesting pictures for the sick kids. A．draw B．to draw C．drawing D．to drawing 【答案】B 【详解】句意：学生们被要求为生病的孩子们画一些有趣的画。 考查非谓语动词。根据短语be asked to do sth.“被要求做某事”可知，空处应选动词不定式to draw。故选B。 10．His father wants him ________ a doctor in the future.
