以下是对这部分内容的详细解析: **一、根据首字母及汉语提示,完成下列单词拼写** 1. “味道”常见的英文单词是“smell”,在这里作主语,故填“smell”。 2. “怀疑”的英文是“doubt”,根据语境,这里用一般现在时,主语是“I”,所以填“doubt”。 3. “剩余”的英文是“remain”,根据“had”可知,句子时态为一般过去时,所以填“remained”。 4. “help sb. do sth.”意为“帮助某人做某事”,“烧开”的英文是“boil”,所以填“boil”。 5. “贸易”的英文是“trade”,“trade”在这里是不可数名词,“do a lot of trade with...”表示“与……做大量贸易”,故填“trade”。 **二、用括号内所给单词的适当形式填空** 6. “a wise”后接名词,“rule”的名词形式“ruler”表示“统治者”,故填“ruler”。 7. “discovery”是名词,前面用形容词修饰,“accident”的形容词形式是“accidental”,表示“偶然的”,故填“accidental”。 8. “treasure”是名词,前面用形容词修饰,“nation”的形容词形式是“national”,“national treasure”表示“国宝”,故填“national”。 9. “with the + 名词 + of...”表示“随着……的……”,“popular”的名词形式是“popularity”,“with the popularity of...”表示“随着……的普及”,故填“popularity”。 10. “water”是名词,前面用形容词修饰,“drink”的形容词形式“drinking”表示“饮用的”,“drinking water”表示“饮用水”,故填“drinking”。 **三、单项填空** 11. 根据“because of the bad weather”可知,飞机因为天气不好在地面又停留了两个多小时。“remain”表示“停留,逗留”,符合语境;“run”意为“跑,运行”;“move”意为“移动”;“shake”意为“摇晃”。所以选D。 12. “thousands of”是固定短语,表示“成千上万的”,用来修饰可数名词复数“hits”,表示“一天有数千次网络点击量”。“thousand”和“hundred”前面有具体数字时,不用复数形式,也不与“of”连用。所以选B。 13. “taste”和“smell”在这里是系动词,系动词没有被动语态,所以排除C和D。根据“ I haven't had it yet.”可知,还没有尝,应该是“闻起来”很香,“smell”表示“闻起来”,符合语境。所以选B。 14. “not...until...”是固定搭配,表示“直到……才……”,根据“it's raining outside”可知,外面在下雨,不要离开,直到雨停。“since”意为“自从,因为”;“when”意为“当……时候”;“after”意为“在……之后”。所以选B。 15. “It is believed that...”是固定句型,表示“人们相信……”,其中“it”作形式主语,真正的主语是后面的“that”从句。所以选C。 **四、根据汉语意思完成下列句子** 16. “偶然地”的英文短语是“by accident”,故填“by accident”。 17. “毫无疑问”的英文短语是“Without doubt”,位于句首,首字母大写,故填“Without doubt”。 18. “发生”的英文短语是“take place”,这里描述的是过去发生的事情,用一般过去时,“take place”的过去式是“took place”,故填“took place”。 19. “不足,少于”的英文短语是“less than”,故填“less than”。 20. “据说”的英文句型是“It is said that...”,故填“It is said”。 **五、完形填空** 21. 根据下文分别介绍了四种卫星(The first kind...The second kind...The third kind...The last kind...),可知人类发明了四种卫星。所以选B。 22. 根据“They are used to make maps.”可知,第一种卫星用于绘制地图,所以它研究的是地球的“地理”情况。“geography”表示“地理”;“physics”表示“物理”;“chemistry”表示“化学”;“biology”表示“生物”。所以选D。 23. 根据“help countries to see where”可知,这些卫星还帮助国家查看哪里可能“找到”石油或黄金。“find”表示“找到”;“carry”表示“携带”;“keep”表示“保持”;“choose”表示“选择”。所以选B。 24. 根据“a message to the satellite”可知,轮船或飞机可以向卫星“发送”信息。“send”表示“发送”;“write”表示“写”;“take”表示“带走”;“bring”表示“带来”。所以选C。 25. 根据“the satellite can find out”以及“the ship or the plane is”可知,卫星可以查明轮船或飞机在“哪里”。“where”表示“哪里”,引导宾语从句,在从句中作地点状语。所以选A。 26. 根据“These satellites...clouds and strong winds moving across the earth.”可知,这些卫星“观察”云层和强风在地球上移动。“watch”表示“观察,观看”,强调长时间地看;“have”表示“有”;“notice”表示“注意到”;“see”表示“看见”,强调看的结果。所以选B。 27. 根据“They warn countries to make preparation”可知,当非常“糟糕的”天气来临时,卫星会警告国家做好准备。“bad”表示“糟糕的”;“sunny”表示“晴朗的”;“cool”表示“凉爽的”;“fine”表示“好的”。所以选C。 28. 根据“Telephone calls...countries can be sent by these satellites.”可知,这里说的是国家“之间”的电话可以通过这些卫星发送。“between”表示“在……之间(两者)”;“after”表示“在……之后”;“before”表示“在……之前”;“for”表示“为了”。所以选C。 29. 根据“The call is sent to the satellite then the...sends it to a station in the country”可知,电话被发送到卫星,然后“卫星”把它发送到这个国家的一个站点。所以选D。 30. 根据“These satellites also...pictures”可知,这些卫星也“传送”图片。“carry”表示“传送,携带”;“make”表示“制作”;“get”表示“得到”;“go”表示“去”。所以选B。
