Yesterday（昨天，过去时间）；B. Tomorrow（明天）、C. Next week（下周）都是将来时间；D. Every Sunday（每周日）用于一般现在时。只有A符合时态要求。 2. 答案：B 解析：Wu Cheng'en（吴承恩）是《西游记》的作者。worker工人，writer作家，teacher老师，driver司机，选writer。 3. 答案：D 解析：第一空often（经常）是一般现在时，主语he是第三人称单数，动词用wears；第二空yesterday（昨天）是一般过去时，wear的过去式是wore。因此搭配为wears; wore。 4. 答案：C 解析：短语辨析： put on 穿上；put away 收好；put up 搭建（帐篷）；put out 扑灭。句中a tent（帐篷）搭配put up，意为搭帐篷。 5. 答案：C 解析：谚语 One tree doesn’t make a forest.独木不成林。寓意是个人力量有限，要团结协作、共同合作。A种树、B树长高、D森林重要都不是这句谚语的内涵，选we should work together。 五、选择恰当句子，补全对话。 1. 答案：C 解析：后文Sarah回答“Yes, I went there with my mom.”，是一般疑问句的肯定回答。只有C选项是一般疑问句，询问是否去了科技展，逻辑匹配。 2. 答案：A 解析：上文问句“Was the science fair fun?（科技展好玩吗？）”，Sarah先用Sure（当然）肯定，接着补充描述展会现场，A选项“有很多超酷的展品”承接语境。 3. 答案：D 解析：后文答句“I liked the robot show best.（我最喜欢机器人表演）”，是在回答最喜欢的事物，D选项正好询问最喜欢的项目，问答对应。 4. 答案：E 解析：上一句问句“What could the robot do?（机器人会做什么？）”，E选项具体介绍机器人的功能，完美对应问题。 5. 答案：B 解析：后文答句“Yes. I did a paper boat water test.”是一般疑问句的肯定回答，还提到了科学小测试，B选项问句正好询问是否做了科学小实验，符合对话逻辑。 六、句子排序。 1. 答案：D. Students in Class One did fun activities on Earth Day. 解析：总起句，交代故事主体（一班学生）、时间（地球日），是整篇短文的开头。 2. 答案：H. They went camping with their teachers. 解析：承接上文，说明具体活动内容：和老师一起去露营。 3. 答案：F. They arrived at the campsite early in the morning. 解析：按照时间顺序，出发后一早抵达露营场地。 4. 答案：B.
