参考答案：
1．A
考查副词。hard猛烈地；hardly几乎不。根据“It’s terrible.”可知，说明雨下得大，常用副词hard；雨下得大，人们几乎不能外出，hardly意为“几乎不”，故选A。
2．C
考查疑问词辨析。How long多长；How far多远；How often多久一次；How much多少钱。根据下文，一个月一次。可知上文提问的是频率，故选C，你多久去一次电影院？
3．D
A. of……的；B. with和…在一起；C. for为了；D. to对着 (某方向或某处) 。the answer to the question为固定短语，意为“这个问题的答案”。故选D。
4．C
考查连词辨析。If如果；When当……时；Although尽管；As当……时；根据语境可知，此处应用although引导让步状语从句，故选C。
5．D
考查频率副词辨析。Always总是；Usually通常；Sometimes有时；Never从不。根据“I only watch movies at home.”可知，我只在家看电影，所以从不去电影院。故选D。
6．A

8．C
考查非谓语动词。分析句子结构可知，it is+adj.+for sb.+to do sth.表示“做某事对某人而言是怎样的”，it在句中作形式主语，真正的主语是动词不定式。
9．D
考查不定代词。either 两者其一；another 另一个；neither 两者都不；none 都不（三者\三者以上）。根据but可知是转折，此处意为“没有人来”，作主语，指人。故选D。

13．B
第一个空，what什么，when什么时候，where哪里，how怎么样；根据回答“7月18日”，可知对时间提问，所以用特殊疑问词when。第二个空，根据后面的July 18th“7月18日”，可知指的是具体的某一天，前面应用介词on；故答案选B。
14．C

16．A
