参考答案：
1．B
【详解】句意：如果你想要保持健康，你应该少吃快餐，多吃新鲜蔬菜。
fewer“更少的”，修饰可数名词；less“更少的”，修饰不可数名词；more“更多的”，修饰可数名词或不可数名词。根据If you want to keep healthy,可知要保持健康，应少吃快餐，多吃新鲜蔬菜。修饰不可数名词fast food，故用less。故选B。
2．B
【详解】句意：艾伦的爸爸希望他的儿子将来能成为一名宇航员。
考查非谓语动词。hope用法为：hope to do sth.或hope sb.+(that)从句。结合语境可知，本句为hope sb+宾语从句的用法。主句为一般现在时，宾语从句遵循“主现从不限”，结合从句时间状语“in the future”可知，从句应用一般将来时。故选C。
3．A
【详解】句意：——我们的教室非常干净。谁把它打扫干净，李明？——对不起，我不知道。我认为有人课前打扫的。
考查不定代词。somebody某人，用于肯定句；nobody没有人；everyone每个人；anyone任何人，用于否定句或疑问句。根据句子结构可知，此处是肯定句，表示有人把教室打扫干净，应用不定代词somebody。故选A。
4．D
【详解】句意：妈妈告诉儿子在她回来之前不要打开盒子。
考查非谓语。此处是tell sb to do sth“告诉某人做某事”，空处用不定式作宾补，否定直接在to前加not，故选D。
5．B
【详解】句意：——你能自己完成你的作业吗？——是的。
考查一般疑问句。根据“Yes, I am”可知，问句为一般疑问句，且句子时态为一般现在时，一般疑问句往往用什么问，用什么答，故第一空应用一个be动词，排除选项C和D，由于句子时态为一般现在时，且问句主语为you“你”，故应用Are，be able to“能”。故选B。
6．B
【详解】句意：我们学校有三千名学生。
考查数词的用法。表示确切数量：基数词+thousand；表示模糊数量：thousands of +名词；结合本题的分析可知，只有选项B符合。故选B。

9．A
【详解】句意：不要担心我们。我们可以互相帮助。我们是好朋友。
考查动词短语。worry about为……担心；think about思考；talk about谈论；care about关心。根据后句“We can help each other. We are good friends.”可以推知前句表示“别为我们担心”。故选A。
10．B
【详解】句意：我恐怕不能在这么短的时间内完成这项任务。你能帮我一下吗？
考查谓语。can能够；be able to能够；be going to do将要；D不能做谓语。根据“I am afraid that I...finish the task in such a short time. Could you help me, please ”可知，强调能力，需要帮助，所以自己完不成。故选B。
11．A
【详解】句意：任何知道这个问题答案的人都可以举手。
考查不定代词。Anyone任何人；Someone某人；Everyone每个人；No one没有人。根据“who knows the answer to the question”可知此处指知道问题答案的任何人，用Anyone。故选A。

【详解】句意：看看学生们！一些学生在看电视，其他学生在互相交谈。
考查代词辨析。the others其余的（表示在一个范围内的其他全部）；others其他人；the other两者中的另一个；other其他的，不能单独使用，后面需要接可数名词复数或不可数名词。空后没有名词且be动词是are，排除C和D，由“Look at the students! Some are watching TV”可知，此处指除了看电视的学生以外的，其余的学生在谈话，排除B，故选A。
13．B
【详解】句意：我希望你有一天去参观我们的学校。
考查动词辨析。hope希望；wish希望；suggest建议；advice建议。根据句意和“you to visit”可知，此处指希望你有一天去参观我们的学校，考查短语“wish sb. to do”“希望某人做某事”，hope不能用hope sb to do sth的结构。故选B。
14．D
【详解】句意：——我没有什么可说的。——我也没有。
考查倒装句。根据“I didn’t have anything to say”可知此处表示“我也没什么可说的”，用“Neither+助动词/be动词/情态动词+主语”结构，排除AC，根据“didn’t”可知助动词用did。故选D。
15．A
【详解】句意：——每个人都在吗？——不，Susan还在路上。

20．句意：我们必须把自己绑在床上，这样我们就不会在睡觉时飘走了！根据“we won’t float away in our sleep”可知为了不在睡觉时飘走要把自己绑在床上，tie“捆，绑”；have to后接动词原形。故填tie。
21．句意：我们必须把自己绑在床上，这样我们就不会在睡觉时飘走了！“we won’t float away in our sleep”是把自己绑在床上的目的，用so that表示“以便”，引导目的状语从句。故填so that。
