五、书面表达
假设你是李华，你的外国笔友 Tom 对沙漠很感兴趣，请你根据本单元所学内容，给他写一封邮件，介绍一下沙漠的情况。
邮件内容包括：
1. 沙漠的气候干燥，很少下雨。
2. 夏天很热，冬天很冷。
3. 有些动植物可以在沙漠中生存。
4. 人们在沙漠中的居住情况。
注意：
1. 词数 80 左右；
2. 邮件的开头和结尾已给出，不计入总词数。
答案及解析：
一、词汇运用
1. dry “干燥的”，形容沙漠的气候。
2. plants “植物”，few 修饰可数名词复数。
3. windows “窗户”，根据前面的“small”可知用复数。
4. summer “夏天”，in summer 表示“在夏天”。
5. lakes “湖”，根据前面的“the”可知用复数。
二、单项选择
1. B little 表示“几乎没有”，修饰不可数名词，符合沙漠少雨的情况；much 和 a lot of 表示“很多”，a little 表示“有一点”，均不符合。
2. D 根据文中提到“it is hot in summer but very cold in winter”可知冬天很冷。
3. B 骆驼能在无水情况下生存很久是因为在驼峰中储存水。
4. D 文中提到“People usually live near the lakes in deserts.”。
5. D 沙漠中房子窗户小是为了阻挡阳光和风。
三、阅读理解
1. C 文中提到“The climate is very hot during the day and very cold at night.”。
2. B 文中提到“They store water in their bodies.”。
3. B 文中提到“People don't often live in the middle of deserts. They usually live near an oasis (绿洲) or a river.”。
4. C 文中提到“An oasis is a place with water and plants in the desert.”。
5. D 文中提到“Some snakes and lizards can also live in deserts. They stay in cool places during the day and come out to look for food at night.”。
四、句型转换
1. Are 陈述句变一般疑问句，将 be 动词提前。
2. is there 前否后肯，little 表示否定，所以反意疑问句用 is there。
3. What's; like 询问天气用“What's the weather like ”。
4. Where do 对地点提问用 where，原句是一般现在时，借助助动词 do。
5. they can 一般疑问句的肯定回答用“Yes, 主语 + 情态动词”。
五、书面表达
