More and more people joined his team to help make Chongqing 49 (beauty). Zhong’s work also shows that everyone can make 50 difference. Giving a helping hand is helpful to ourselves. Why not do something like Zhong to make our school, our city better? Water is very important to us. We use it in many ways. In our daily life, we need 51 (drink) water to stay healthy. But do you know how much water we should drink every day? A lot of people think they should drink eight glasses of water a day. But in fact, the amount of water we need 52 (depend) on many factors, such as our age, weight and activity level. For example, if you are very active and do a lot of sports, you need 53 (drink) more water. You should also drink more water in hot weather. However, not everyone has enough clean water 54 (use). In some places, water is very scarce. People there don’t have 55 (much) water for daily use. We should save water. We can start from small things. For example, when we brush our teeth, we should turn 56 the tap. We can also use 57 (reuse) water to water plants. In addition, water pollution is a big problem. Factories and farms often put 58 (harm) chemicals into rivers and lakes. This makes the water undrinkable. We need to protect water resources and stop 59 (pollute) water. If we all work together, we can make a difference and ensure that there is enough clean water 60 future generations. $ 班级 姓名 学号 分数 Unit 5 Water is life 单元重点单词变形短语语法句型精练 （时间：60分钟，满分：80分） 单元知识点默写 一、重点单词词性转换 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 1. eventually (adv.) → eventual (adj.) 最终的 2. public (adj.) → publicity (n.) 公开；宣传 3. agriculture (n.) → agricultural (adj.) 农业的 4. globe (n.) → global (adj.) 全球的；全世界的 5. industry (n.) → industrial (adj.) 工业的 6. fix (v.) → fixed (adj.) 固定的 7. busy (adj.) → business (n.) 买卖；生意 8. safe (adj.) → safety (n.) 安全；平安 9. use (v.) → useful (adj.) 有用的 10. care (v.) → careful (adj.) 小心的；仔细的 二、重点单词默写 1. everyday (adj.) 每天的；日常的 2. form (n.) 类型；种类 3. journey (n.) （尤指长途）旅行 4. drop (n.) 滴；水珠 5. tap (n.) 水龙头 6. voice (n.) 说话声 7. pipe (n.) 管子；管道 8. return (v.) 回去；返回 9. rush (v.) 迅速移动 10. bath (n.) 洗澡；洗浴 11. salt (adj.) 含盐的；咸的 12. brain (n.) 脑 13. population (n.) 人口 14. trade (n.) 贸易；买卖 15. role (n.) 角色 16. goods (n.) 商品；货品 17. overseas (adv.) 在国外；向海外 18. income (n.) 收入；收益；所得 19. nearly (adv.) 几乎；差不多；将近 20. leisure (n.) 闲暇；空闲；休闲 21. throughout (prep.) 自始至终；贯穿整个时期 22. duty (n.) 责任；义务 三、短语默写 1. a bit 有点儿；稍微 2. at once 立即；马上 3. drinking water 饮用水 4. play a role in … 在……起作用 5. steam engine 蒸汽机 6. as a result 作为结果；因此 7. make sure 确保；设法保证 8. have something in common 有相同的特征（或特点等） 9. run out of 用完；耗尽 10. care about 关注；担忧 单元知识点习题训练 1、 用括号内所给单词的适当形式填空(本大题共15小题，每小题1分，共15分) 1．The math problem is so difficult, so few ________ (student) can work it out. 【答案】students 【详解】句意：这道数学题太难了，所以很少学生能做出来。句中“few”表示“很少，不多”，后接可数名词复数形式，“student”的复数形式为“students”。 2．Please tell everyone not ________ (waste) water. 【答案】to waste 【详解】句意：请告诉所有人不要浪费水。根据“Please tell everyone not...water.”可知，“tell sb. not to do sth.”是固定句型，意为“告诉某人不要做某事”。故填to waste。 3．It was difficult to get ________ (drink) water here in the past. 【答案】drinking 【详解】句意：过去在这里很难获得饮用水。根据“It was difficult to get ...
