1．A
【详解】句意：——我非常想念我的妈妈。——为什么不打电话给她？
考查固定搭配以及动词短语。why dn’t yu d=why nt d“为什么不……？”，后接动词原形，排除C和D；call up“打电话”；call n“号召”，故选A。
2．C
【详解】句意：——我从未参观过造纸厂。——我也没有。
考查倒装句。“S+情态动词/助动词/be+另一主语”表示某人也是，前面提到的是一种肯定情况；“ Neither/Nr+情态助动词/助动词/ be+另一主语”表示某人也不是，前面提到的是一种否定情况。上句为否定情况，此句应表示“我也没有”，故选C。
3．B
【详解】句意：大约五分之二的人不喜欢看电影。
考查英语中分数的表达。英语中的分数由基数词和序数词一起表示，基数词作分子在前，序数词作分母在后，分子大于1，分母要用复数形式。故“五分之二”的正确表达为tw fifths。故选B。
4．B
【详解】句意：这个男孩因为生病被送去医院。
考查短语。as fr关于；because f因为；as a result结果；thanks t幸亏。根据“his illness”，可知句子表达去医院的原因是生病了，用短语“because f”。故选B。

【详解】句意：最近几年，中国发生了巨大的变化。
考查时态。根据“in recent years”可知，句子要用在现在完成时，排除C；take place/happen“发生”，无被动语态；故选D。

thusand 千，表示确切数目时不用复数形式，也不与f连用。但表示概数时必须用复数，并且与f连用。thusands f “成千上万的”，所以选D。
7．C

考点：考查形容词辨析。
8．C
【详解】试题分析：句意：-过去，大多数青少年不得不为地主在田野上劳作来帮助支撑他们的家人，因为他们的家庭不能为他们负担起教育费用。-真遗憾！affrd 指“提供，供给”，还可以特指经济能力，负担得起。supply 指“供给，补充，弥补”，还可作名词，意为“供给（量），物资，存货”； supprt支持；give给。所以选C。
考点：考查动词辨析。
9．B
【详解】句意：对你来说每天锻炼是必要的。
“It’s+形容词+t d sth.”是一个固定句型，意思是做某事是...的。所以选B。
10．D
【详解】句意：他告诉采访者他已经没有钱买旧自行车了。
put away 抛弃，储存；turned ff 关闭；taken ut 取出，拿出；used up 用完，耗尽。结合语境后面是买自行车，只能是没钱买了，可知选D。
11．B
【详解】句意：外国人晚上到达上海。

12．B
【详解】句意：我们的老师告诉我们，光传播的速度比声音快得多。
在含有宾语从句的主从复合句中，当主句用了一般过去时态时，宾语从句也要用相应的过去时态。但当宾语从句表示客观真理时要用一般现在时。光传播的速度比声音快，既是客观真理。所以选B。
13．C
【详解】句意：在过去的2年里她取得了很大的进步。
根据“in the past 2 years”可知该用现在完成时，结构为have/has dne,make的过去分词为made，所以选C。
14．B
【详解】句意：在政府的帮助下，贫困的孩子可以得到良好的教育。
考查介词的辨析和冠词a/an区别。第一个空，“在……的帮助下”with the help f …，是固定短语。第二个空，泛指一个好的教育，gd是以辅音音素/g/开头，用a修饰。故选B。
15．D
【详解】句意：——你看见我的钢笔了吗？——是的，我看见了。我刚才看见它在你的课桌上。
考查一般疑问句和动词时态。根据回答“Yes, I have.”可知问句应是由“Have”开头的一般疑问句，因此用现在完成时“Have yu seen”。故选D。

37．细节理解题。根据第二段“Lima’s ppulatin…but it grew t 9.1 millin in 2000. Tianjin’s…In 2000, it bsted t 9.7 millin. Mexic city…But in 2000, its ppulatin reached 25.8 millin.”可知，2000年人口最多的城市是墨西哥城，故选C。
