本单元重点难点分析
1．have been (to) 与have gone (to)
have been与have gone都表示现在完成时态，说明动作已经发生了，但它们之间的含义是有不同的。

1〕"have been in + 地点名词"或者"have been + 表位置的副词"
含义是"在某地呆得过多久"。

例如：
Mr Zhang has been in this school for ten years．He knows everyone here.
张先生在这所呆了十年。

I have been here since I began to work．Its just like my home.
我工作以来始终呆在这里。

2〕"have been to +地点名词"表示"曾经到某地去过〔多少次〕"。

例如：
Miss Brown has been to China twice．Thats why she speaks Japanese very well.
布朗小姐来过中国两次。

Have you ever been here before
你以前到过这儿吗
3〕"have gone to +地点名词"或"have gone + 表位置的副词"其含
义是"到某地去了"〔人已不在此地〕，留意：这种结构不用于第一人称，也不用于其次人称，它仅用于第三人称。

请看下面一段对话：A: Wheres Tom
B: Hes gone to the shop.
A: Has Mary gone there with him
B: No, she hasnt.
A：汤姆在哪里
B：他到商店去了。

A：玛丽跟他去了吗
B：没有。

2. Businessmen are afraid of newspapers and TV stations. 生意人可
怕报纸和电台。

be afraid of… 意思是"可怕……"。

afraid是形容词，在句中只能作表语，后跟名词或动词的-ing形式〔指自己不能打算而突然发生的事〕，与frightened的意思相同。

be afraid后也可跟动词不定式表示"可怕做某事"即：be afraid to do sth.。

另外，afraid后还可跟that引导的宾语从句，意思是"担忧，生怕"。

例如：
〔1〕I am afraid of mice. 我可怕老鼠。

〔2〕Dont be afraid of making mistakes. 不要怕犯错误。

〔3〕Im afraid to tell her the truth. 我不敢告知她真相。

〔4〕I am afraid you are ill. 生怕你是病了。

〔5 〕Im afraid (that) we may not catch the train. 我担忧我们可能赶不上火车。

3. As soon as other people hear it, they go out with their rubbish
and throw it in.
当人们一听到它，他们就出来把垃圾扔进去。

as soon as -……就……，引导时间状语从句，表示主句的动作紧跟
从句的动作发生。

必需留意as soon as possible〔one can〕，它表示"
尽可能快地"。

【例】
〔1〕Hell write to me as soon as he gets to Beijing．
他一到北京就会给我写信。

〔2〕You should do your work as soon as possible．
你应尽快地做事。

4. … taking care of our environment is very important. 爱护好我们
的环境是格外重要的。

(1) take care of爱护，照看，保管。

如：
Please take good care of your books. 请保管好你们的书。

Can you take care of my baby while Im away 我出去时你能为我照
看我的孩子吗
(2) "Taking care of our environment" 在这里是动名词短语作主语。

也可以说：Its very important to take care of our environment.
5．Its our duty to keep our environment clean and tidy. 保持我们的
环境洁净洁净是我们的责任。

〔1〕it在这里是形式主语，真正的主语是"to keep our environment clean and tidy"
又如：Its a pleasant way to help keep our city clean.
〔2〕keen后面可跟带现在分词的复合结构。

如：
He kept me waiting for a long time yesterday．他昨天让我等了很长时间。

keep后面也可跟带形容词的复合结构。

如：
You should take more exercise to keep you healthy．你应当多运动来保持健康。

6．If everyone makes a contribution to protecting the environment, the world will become much more beautiful. 假如每人都对爱护环境做出奉献，那么世界将变得更加秀丽。

make a contribution to…意思是"对……做奉献，捐赠"。

to是介词后跟名词或动词的-ing形式。

例如：
〔l〕Thomas made a great contribution to the world．托马斯·爱迪生对世界做出了很大的奉献。

〔2〕It is our duty to make a contribution to protecting the environment．为环境爱护做奉献是我们的责任。

make是英语中格外活泼的动词之一，和不同的词搭配具有不同的含义。

又如：
make a face做鬼脸make a living谋生
make a mistake犯错误make friends with交伴侣
make fun of开玩笑make ones way挤出一条路
make room for让座make up ones mind下决心
My friend Emma made fun of my job once time. She said that my job is rather making a living than career manage. I made up my mind to run my company successfully, which could make her realize she had made such a mistake. Then I made my way in mass society. I made good as a manager. I stay here and make sure that I have made a go of the business. I make of what Emma have done for me, luckily, I made friend with her.
7. The more trees, the better的结构
这里是"the more，the more…"句型表述结构，它的意思是"越多越好；越……，越……"。

例如：
Start your work, the sooner, the better.
开头工作吧，越快越好。

The more I think of it, the happier I am.
我越想越欢快：
The harder you work, the greater progress you will make.
