III.Ask students to go through the text.Then ask some students to translate the text to get the main idea of the text.参考译文：
1858年，一位名叫埃梅·托梅·德·干蒙的法国工程师带着建造一条长21英里、穿越英吉利海峡的隧道计划到了英国。他说，可以在隧道中央建造一座平台，这座平台将用作码头和火车站。如果再建些伸出海面的高大的烟囱状通风管，隧道就具备了良好的通风条件。1860年，一位名叫威廉·洛的英国人提出了一项更好的计划。他提议建一条双轨隧道，这样就解决了通风问题。因为如果有一列火车开进隧道，它就把新鲜空气随之抽进了隧道。42年以后，隧道实际已经开始建了。如果不是因为那时英国人害怕入侵，隧道早已建成了。世界不得不再等将近100年才看到海峡隧道竣工。它于1994年3月7日正式开通，将英国与欧洲大陆连到了一起。
IV.Explain the text in details.1,In 1858, a French engineer, Aime Thome de Gamond, arrived in England with a plan for a twenty-one-mile tunnel under the English Channel.Plan for+ noun./动名词
······的计划
Twenty-one-mile 加连字符，用单数，作定语
for a ```Channel是介词短语，作定语，修饰名词plan。
2.This platform would serve as a port and a railway station.serve as ```=serve for```
起······作用，用作······，充当······
eg.It will serve as a swimming pool.This sofa can serve as/for(a)bed.serve ```with
拿出······款待某人
eg.The waiter served us with wine.3.In 1860, a better plan was put forward by an Englishman, William Low.put forward(plan/suggestion)
提出（计划、建议等）
eg.You know they wouldn’t accept your plan.Why did you put it forward?
4.He suggested that a double railway-tunnel should be built.suggest
① vt.暗示，用法与其他的词相同
（问某人）建议某事、做某事 suggest sth.(to sb.)/suggest doing sth.② vt.建议，用虚拟语气，后接动词是要用-ing形式，后接that从句采用一种固定的用法“should+动词原形”（should可省略）
类似的动词还有：demand, recommend, order, insist 表建议，请求，命令 eg.I suggested(that)he(should)go home.(that, should都可省略)He suggest that I should go with him.他建议我一定要跟他去。insist 作“坚持”讲时用法同suggest eg.He insisted that I should stay to lunch.他坚持要留下来吃晚饭。
5.This would solve the problem of ventilation, for if a train entered this tunnel, it would draw in fresh air behind it.draw in
吸进，如用bring没有draw in 形象、贴切 draw in
靠到路边，跌向路旁 draw back 退回 draw off
走了 draw up
停下来
6.If, at the time, the Britiish had not feared invasion, it would have been completed.虚拟语气(非真实条件句)包括A与现在事实相反和B与过去事实相反 其从句的使用
A、与现在事实相反, 用一般过去时
B、与过去事实相反, 用过去完成时, 此时主句格式为would have done（would/could/should 都可以）
must have done对过去的推测 can't have done对过去的推测
情态动词加have done 表示对过去的推测
7.The world had to wait almost another 100 years for the Channel Tunnel.wait(for)some times
I have waited five minutes.(for 可不要)
I have waited for you(for)five minutes.I have waited five years for you.8.It was officially opened on March 7,1994,finally connecting Britain to the European continent.现在分词 connecting 引导的短语相当于一个并列分句。connect表示“连接”、“连结”，可与to或with连用：
This road connects the willage with/to London.这条公路连接着这个村子与伦敦。
The lake and the canal are connected by a river.这个湖与运河之间由一条小河相连。

VI.Introducd the key structures to the students
1.虚拟语气 与过去事实相反
真实条件句所表的假设是可能发生和实现的，是与实施相符的。
E.g.if it is fine tomorrow, I will go to visit my grandpa.非真实条件句所表达的假设则不可能或不大可能发生或实现的，与事实相反的情况。
If I were a bird, I would fly to America.虚拟语气在非真实条件句中:
a.与现在事实相反
If I won the lottery, I would buy an expensive car.b.与过去事实相反
If he had driven more carefully, he would not have had the car accident yesterday.c.与过去事实可能相反或发生实现几率较小。
If you got/were to/should get a full mark next time.I would hold a party for you
特殊结构 : suggest/insist, 后接that从句(should+动词原形)条件句有真实条件句和非真实条件句两种。
Suggest, demand, order, propose, insist command ,request, desire后的宾语从句中：（should)+动词原形。
I suggest that we(should)set off at once.I demanded that he(should)answer me immediately.Do some exercise in cla and check the answer.Explain the key points.Give the correct form of the verbs in parentheses.1.If you had told me about it earlier, I________(be able)to help you.2.If you_______(can/come)with us, we would have been pleased.3.You_________(not make)such a mistake if you had been more careful.4.If father_______(be)alive, he would be horrified.5.If it_______(be)fine tomorrow, we shall go for a swim.Answers 1 would have been able would have done 跟过去事实相反,从句会使用had done
could have done, 情态动词后面一旦加了have done 表示跟过去有关 3 would not have made were : 虚拟语气与现在事实相反,从句使用一般过去时,与一般现在时相反的be 动词,用were代替 if I were you 5 is 真实条件句

第3类条件句是在if从句里设想纯粹想像的事情，在主句里讲述想像的结果，谈的是没有或永远不可能有的结果，指的是过去没有过的事情。第3类条件句的基本结构是if从句用过去完成时，主句用would have/ should have +过去分词：
If it had rained, we would have stayed at home.在if从句中可用could have +过去分词代替had been able to +动词原形： I’d have read that book if I could have bought it.VI.【Special difficulties】
