参考答案
一、1. backpack 2. burn 3. cream 4. officer 5. market
二、1. keep walking 2. fed 3. luckily 4. says/said goodbye to 5. officer
三、1. A【解析】考查数词的用法。hundred、thousand、million等数词与具体数字连用时，用单数形式，且词尾不加-s；若与of连用表示约数时，词尾必须加-s，且不可与数词连用。hundreds of意为“成百上千的”，所以选A。
2. C【解析】pick up“捡起，拾起”；wake up“叫醒，唤醒”；stay up“熬夜”；put up“举起，搭建”。由上文句意“你看起来疲乏”和下文句意“昨天晚上为期末考试做准备”可知，是“熬夜”了。所以选C。
3. D【解析】句意：—理查德还住在这里吗？—不，他已经搬到巴黎去了。由答语中already一词可知，本句为现在完成时。故选D。
4. D【解析】stay up“熬夜”；go up“上升”；give up“放弃”；show up“露面”。由句意“你知道约翰在哪里吗？他准备和我早点见面，但他没露面”可知选D。
5. B【解析】本句为肯定句，排除A和C；else修饰复合不定代词时，else要放在其后。故选B。
6.C【解析】考查动词短语辨析。take out “取出，除去”；take away “带走；拿走”；take off “起飞”，根据答语：别急，飞机将在2个小时后起飞。故选C。
7. B【解析】由句意“在那个神奇的世界里，死人能复活，断腿能再生”可知，选B，alive意为“活着的”，指生命的延续。
8. B【解析】at last“最后”；at least“至少”；at once“马上”；at all“全然”。由句意“老师要我们每个人至少植六棵树”可知，选B。
9. A【解析】get a chance to do sth.意为“得到机会做某事”。
10. B【解析】think to oneself是固定搭配，意为“心里想，盘算”。由句意“海伦不喜欢和他人谈话，她总是喜欢自己心里想（事情）”。
11. B【解析】考查动词的时态与语态。第一空要表达“对不起，他们全卖没了”，they和sell out之间是一种被动关系，所以要用被动语态；第二空，表达产品畅销使用sell well主动表被动，所以选B。
12.C【解析】考查动词短语的辨析。stand for“代表;主张”;belong to“属于”;hear about“听说”;keep to“遵守”。根据句意知选C。
13. B【解析】 no problem“没问题”，表示愿意或能够做这件事。
