When we finish reading a newspaper, the paper will become waste. When TV sets or computers are broken, they will become electronic waste.
Plastic bags are often used in our everyday life. The number of used plastic bags is increasing day by day. We like to use plastic bags because they are convenient. When we get home, we throw the plastics away. These are called "white pollution" as most plastics are white. Rubber is also common in our daily life. Many of our products are made of rubber, just like the tyres (轮胎) and the bottom part of our shoes. It's true that rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a long time. The old rubber pollutes environment very badly because it can't break down easily in nature—it will stay unchanged for a long time. This is really a big problem all over the world.
Everyone should play a part in saving our world. For example, when we go shopping, we can bring cloth bags instead of plastic ones. And we should do something to recycle rubber. Our small actions can make a difference and lead to a better future.
15. Which of the following things probably becomes electronic waste
A.The TV set. B.The plastic bag.
C.The newspaper. D.The rubber.

they are always used.
D.Because they are used several times.

D.The new plastics pollute the environment badly.

答案
1 . D

考查冠词。a 一个，放在辅音音素开头的单词前面；an 一个，放在元音音素开头的单词前面；the 这个，表特指；/ 表示不用冠词。根据 Go to _____ sleep，因此可知 Go to sleep 是固定结构，空格处不需要冠词，因此可知这句话的意思是“早点睡觉，那么你就能在明天的课堂上集中精力了。”故答案选 D。
2 . B
【解析】
根据本题问句的时态可知，答语的时态应是一般过去时，故 learned 符合题意。
3 . B
【解析】
句意：一一你上周末去哪儿了 ——我去长城了。由 last weekend 可知，此处用一般过去时表达。
4 . D
【解析】
句意为：——我父亲过去常乘公共汽车去上班，但现在他习惯骑自行车去那儿。——真的吗？骑自行车对他的健康有好处。used to do sth 意为“过去常常做某事”；be used to doing sth 意为“习惯做某事”。根据句意，故选 D 项。
5 . C
6 . B
7 . B
【解析】
考查一般过去时。句意：许多非洲人在上个月前往长沙参加了中非博览会。
A.一般现在时；B.一般过去时；C.现在进行时。根据句尾的时间状语为 last month，意为，上个月，因此本句的时态为一般过去时。故选：B。
8 . B
【解析】
根据时间状语 now 结合语境推测句意是“——妈妈，你能帮我吗？——稍等一下，我正在做晚饭。”，由此判断设空处的动作在说话时刻正在进行着，所以用现在进行时，现在进行时的构成是：主语+am/ is/ are+动词的现在分词；故答案为 B。
9 . D
【解析】
根据句意“在过去的几个月里，关于基因编辑婴儿的实验在公众中引起了很多争论”和时间状语 in the past few months 可知，要用现在完成时，其构成为 have/ has done。
10 . D
【解析】
句意：——吴老师，下周我们一定要读一些什么吗？——当然，你们要读《黑骏马》从 58 页到 85 页。考查一般现在时的被动语态。根据上文“Do we have to read anything next week, Mr Wu ”结合“Sure, You…to read Black Beauty from pages 58 to 85.”可知主语和谓语动词 expect 之间存在逻辑上的动宾关系，因此用被动语态，句子时态是一般现在时，因此用一般现在时的被动语态，即 be+动词的过去分词,主语是 you，be 动词用 are，expect 的过去分词是 expected。
11 . C
12 . B
13 . C
14 . D
