知识概要
课时讲练
1.After our lesson on the environment, I’m worried about the future. 上完有关环境的课后，我对未来感到担心。
worried作形容词，意为“担心的，焦虑的”。be worried about（强调状态）意为“担心”，同义短语为worry about（强调动作）。例如：
They worry about the bad weather. = They are worried about the bad weather. 他们担心坏天气。
Unit 1
2.If the rivers are polluted, farmers can’t use the water for their crops. 如果河流受到污染，农民就不能用河水去浇灌庄稼。
pollute作及物动词，意为“污染”。其名词为pollution，意为“污染”;其形容词为polluted,意为“被污染的”。例如：
Please don’t pollute the water. 请不要污染水。
3.It’s no use talking about things we can’t do. 谈论我们不能做的事是没有意义的。
“It’s no use doing sth”意为“做某事是没有用的”。其中it是形式主语，真正的主语是后面的动名词短语。例如：
It’s no use crying. 哭是没有用的。
4.At a green school, every class collects waste which can be recycled or used again. 在绿色学校里，每个班都收集可循环再生或再利用的废物。
（1）waste的用法：
①waste作名词，意为“废弃物；浪费”，常用于“It’s a waste of time/money/... to do sth”，意为“做某事是浪费时间/金钱/……的”。例如：
It’s a waste of time to wait any longer. 再等下去是白费时间。
②waste作动词，意为“浪费；滥用”。常用于“waste time （in） doing sth”，意为“浪费时间做某事”。或用于“waste time/money on sth”，意为“在某事上浪费时间/金钱”。例如：
Don’t waste time （in） playing computer games. 不要浪费时间玩电脑游戏。
（2）recycle作动词，意为“回收利用；再使用”。re-是表示“重复；又”的前缀。类似的词还有reuse“重新使用”，rewrite“重写”，retell“复述”，rebuild“重建”等。例如：
We should recycle all our waste paper. 我们应该回收利用我们所有的废纸。
5.That means less waste. 那意味着减少浪费。
less可作形容词、副词，意为“较少的（地）；较小的（地）”，是little的比较级。常用于less than，意为“少于”。例如：
There are less than 10 customers in the restaurant. 这家饭店的顾客不到10人。
The doctor advises Jim to eat less and exercise more. 医生建议吉姆少吃多锻炼。
6.Though pollution is heavy now, I don’t think it’s hopeless. 尽管现在污染很严重，我认为还是有希望的。
hopeless作形容词，意为“无望的”。由“hope+后缀-less”构成。其反义词为hopeful，意为“抱有希望的”。-less是常见的形容词后缀，可加在一些名词之后，表示“无……，没有……”。常见的加后缀-less构成的形容词：careless“粗心的”，useless“无用的”，homeless“无家可归的”等。例如：
It’s hopeless to change the bad situation here. 改变这个地方的糟糕状况几乎是没有希望的。
【拓展】动词hope，意为“希望”，常接动词不定式或that从句，意为“希望去做某事”。例如：
I hope to become a doctor in the future. 我希望将来能够成为一名医生。
【注意】不能用hope sb to do sth 结构。

五、阅读理解。判断句子正（T）误（F）。
You must have many textbooks. After graduating old textbooks are thrown away, which is a big waste of money and paper.
According to a survey, students across the country buy 2.8 billion（十亿） new textbooks every year. If the following year’s students could reuse these textbooks, it would save over 20 billion yuan per year. That’s enough money to build 40,000 primary schools.
Primary and junior high school students in several Chinese cities are reusing music, arts, science and IT textbooks. That’s because students don’t have to take notes in their textbooks for these subjects, which makes them suitable for recycling. However, most of other textbooks still end up as waste. So we have to do something to stop it.
In fact, many countries already reuse their textbooks. In the US, book companies will come to schools and buy used books. They then resell them to new students the following year at a lower price. A high school textbook in the US can have up to eight owners before it is no longer in a good enough condition to be used. The books can then be recycled.
1.We can save lots of money to build primary schools by reusing
textbooks.( )

2.In many Chinese cities, primary and junior high schools have already
reused all the textbooks.( )

5.According to the writer, it’s unnecessary to reuse the textbooks.( )

Unit 2
1.And what do you do with the bottles when they are empty 瓶子空了时你怎样处理它们？
do with意为“处理，处置，对付”，特殊疑问句中常与what连用，侧重于对某事物的利用或处置。“What do you do with... ”意为“你怎样处理……”。例如：
What will you do with your old books 你将怎样处理你的旧书？
【辨析】deal with意为“处理，应付，对付”，特殊疑问句中常与how连用。例如：
How will you deal with the naughty boy 你将怎样处置这个淘气的男孩？

Miss Li divided her class into five groups. 李老师把她的班分成五个组。
（2）throw away意为“扔掉；丢弃”。该短语为“动词+副词”结构，当宾语是代词时，代词要放在短语中间。例如：
The food got bad. I have thrown it away. 那食物坏了。我把它扔掉了。
3. ... , and it is harmful to our environment. ……这对我们的环境是有害的。
harmful意为“有害的”，其反义词是harmless，意为“无害的”。其名词和动词形式都是harm，意为“伤害；害处”。be harmful to= do harm to，意为“对……有害”。例如：
Fruit juice can be harmful to children’s teeth. 果汁可能损坏儿童的牙齿。
4.Repair them if possible. 如果可能，修理它们。
if possible意为“如果可能”，是if it is possible的省略。例如：

We all waste food, you and me, every day, millions of tons of it. In China, enough food is wasted in restaurants every year to feed 200 million people. And the amount of food wasted by Chinese consumers is increasing fast. So our nation is being encouraged to stop wasting food.
So what should Chinese consumers do to prevent food waste
Keep a kitchen diary
All of us should keep a kitchen diary, and we can know how much food we waste at home. The first thing for us to do is to stop throwing away food that we can still eat. We should eat everything we buy and if we cannot, we should buy less.
Buy only what we need
We should ask for smaller portions in stores. We should also check how much food we have before buying more. We shouldn’t bring much food we don’t need home even if large posters ask us to do so.
Develop the habit of packing food
Chinese consumers are generous and friendly. In restaurants, often too much food is ordered and served. So when ordering out, we are supposed to exclude（排除） the food in the order if we don’t plan to eat it. And order smaller servings in restaurants and take home what we cannot finish.
Don’t put it off!Let’s stop food waste today!
1.Why is our nation being encouraged to stop wasting food ( )
C
A.Because there’s enough food for Chinese people.
B.Because Chinese consumers like to try delicious food.

五、书面表达。
下周英语角活动的主题是“How to protect the environment”，请你根据下面表格里的提示内容写一篇80词左右的英语短文，为英语角活动做准备。
个人 政府
1.步行或坐公共汽车出行 2.自带购物袋购物 3.少用空调（air conditioner） 1.鼓励人们热爱环境
2.阻止工厂的污染
3.阻止河流被污染
______________________________________________________________
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
To protect the environment, both people and the government should do something.
As common people, we should walk or take buses instead of driving cars. When we go shopping, we should take our own bags. Try not to ask for plastic bags. At home, we should try to use air conditioners less to save energy. I think if everyone takes a small step, we can make a big difference.
The government should encourage people to love the environment. It must try its best to stop pollution from factories in cities and villages. And it must stop rivers being polluted.
