production n. 生产；产量
e.g. The factory produces cars. 这家工厂生产汽车。
They put a new product on the market.
他们向市场推出了一款新产品。
Thousands of men were employed in the production of cars.

这所学校有三千名学生。
The project will save billions of trees.

类似的还有
hundreds of 成百上千的；thousands of 成千上万的；billions of 数十亿的
注意：当million 前有不定冠词a或者基数词修饰时，million不加s
如 five million 五百万
(3) ton n. 吨；大量；许多
ton 作可数名词，意为“吨”。
tons of 意为“大量，许多”，后接不可数名词或可数名词复数，相当于a lot of 或lots of。
e.g. An elephant weighs about several tons.
一头大象重达几吨。
I have tons of work to do before the deadline.
在截止日期之前，我有很多工作要做。
Trucks can carry many tons of goods.
卡车可以运载很多吨货物。
2. We use many plastic products only once or twice before they become waste. 许多塑料制品在成为废物之前，我们只使用过一两次。
(1)分析结构：这是一个含有before 引导的时间状语从句的复合句。We use many plastic products only once or twice 是主句：We 是主语；use 是谓语；many plastic products 是宾语；only once or twice 是状语。before they become waste 是时间状语从句：they 是从句主语；become 是从句谓语；waste 是从句宾语。
e.g. We should leave immediately before it starts raining.
我们应该在下雨前立刻离开。
I will not watch TV until I finish my chores.
我做完家务后才会看电视。
(2)waste ①n. 垃圾；浪费
e.g. Throwing away food is a waste of money.
扔掉食物是 浪费钱 。
waste ②v. 浪费（ 反义词：save）
常见搭配：waste sth. on sb./sth. 在某人/ 某事上浪费某物

3. Plastic will stay in the ground for years and pollute the soil, water , and plants. 塑料会在地里存留多年，污染土壤、水和植物。

air/ noise/ water/ light pollution 空气/噪音/水/光污染
e.g. Your car will pollute less if you drive slowly.
慢速驾驶能减少汽车污染。
polluted adj. 受污染的
e.g. Can polluted water be cleaned？被污染的水能净化吗？
4. If our environment suffers, humans will do too.

5. They are indeed easy to carry and cheap to buy.
它们的确携带方便并且价格便宜。
cheap adj. 便宜的
e.g. That store always has cheap prices on clothes.
那家商店的衣服价格总是很便宜。
形容某物价格高低要用high/low，不能用cheap/expensive。high/low 更直接地描述了价格水平的高低，而cheap/ expensive 则更多的是从消费者的主观感受出发，描述物品是否便宜或昂贵。
反义词：expensive/dear “昂贵的”
6. But they are not the only option! 但它们并不是唯一的选择！
option n. 选择；选择权

8. Small changes in our daily habits will have a big impact on reducing plastic waste.我们常习惯中的小小改变将对减少塑料垃圾产生巨大的影响。
(1)分析结构：这是一个简单句。主语是Small changes in our daily habits，其中in our daily habits是介词短语作后置定语，修饰Small changes，说明变化的方面；谓语是will have；宾语是a big impact，on reducing plastic waste 是介词短语作后置定语，修饰impact，说明影响的具体领域。
e.g. Recycling has an impact on the environment.
回收利用对环境有影响。
② v. 有作用；冲击
e.g. Factories often impact the clean water in rivers.
工厂经常影响河流里的干净水源。
