Why was the first tunnel not completed?
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. He said that it would be possible to build a platform in the centre of the Channel. This platform would serve as a port and a railway station. The tunnel would be well-ventilated if tall chimneys were built above sea level. In 1860, a better plan was put forward by an Englishman, William Low. He suggested that a double railway-tunnel should be built. This would solve the problem of ventilation, for if a train entered this tunnel, it would draw in fresh air behind it. Forty-two years later a tunnel was actually begun. If, at the time, the British had not feared invasion, it would have been completed. The world had to wait almost another 100 years for the Channel Tunnel. It was officially opened on March 7,1994, finally connecting Britain to the European continent.

參考譯文
1858年,一位名叫埃梅.托梅.德.干蒙的法國(guó)工程師帶著建造一條長(zhǎng)21英里、穿越英吉利海陜的隧道計(jì)劃到了英國(guó)。他說(shuō),可以在隧道中央建造一座平臺(tái),這座平臺(tái)將用作碼頭和火車站。如果再建些伸出海面的高大的煙囪狀通風(fēng)管,隧道就具備了良好的通風(fēng)條件。1860年,一位名叫威廉.洛的英國(guó)人提出了一項(xiàng)更好的計(jì)劃。他提議建一條雙軌隧道,這樣就解決了通風(fēng)問(wèn)題。因?yàn)槿绻辛谢疖囬_進(jìn)隧道,它就把新鮮空氣隨之抽進(jìn)了隧道。42年以后,隧道實(shí)際已經(jīng)開始建了。如果不是因?yàn)槟菚r(shí)英國(guó)人害怕入侵,隧道早已建成了。世界不得不再等將近100年才看到海峽隧道竣工。它于1994年3月7日正式開通,將英國(guó)與歐洲大陸連到了一起。
自學(xué)導(dǎo)讀
1.a plan for a twenty-one-mile tunnel,建造一條長(zhǎng) 21英里的隧道的計(jì)劃。
twenty-one-mile作 tunnel的修飾語(yǔ),注意 mile為單數(shù)。plan for +名詞/動(dòng)名詞表示“……的計(jì)劃”:
They always make plans for their holidays, but, in the end, they always stay at home.
他們總是為假期制訂各種計(jì)劃,但是,末了,他們總是呆在家里。
He came with a plan for (building) a bridge over the river.
他帶來(lái)了在這條河上建一座橋的計(jì)劃。
2.serve as,充當(dāng),起……的作用(也可以說(shuō) serve for)。
The books on the floor may serve as/ for a carpet.
地板上的書可充當(dāng)?shù)靥河昧恕?/p>
This sofa can serve as/ for(a) bed.
這張沙發(fā)可以當(dāng)床用。
3.a better plan was put forward, 提出了一項(xiàng)更好的計(jì)劃。
put forward為固定短語(yǔ),可分開用,其含義之一是“提出(計(jì)劃、建議等)”:
You know they wouldn't accept your plan. Why did you put it forward?
你知道他們不會(huì)接受你的計(jì)劃。你為什么要提出來(lái)呢?
Has he put forward any suggestion?
他提出什么建議了嗎?
4.He suggested that a double railway-tunnel should be built.他提
議建一條雙軌隧道。
suggest后面跟從句時(shí),從句的謂語(yǔ)動(dòng)詞形式為 should(可省略)+動(dòng)詞原形(cf.第63課語(yǔ)法):
He suggested (that) they (should) change the plans.
他建議他們改變計(jì)劃。
suggest后面也可以跟名詞或動(dòng)名詞形式。(cf.第47課詞匯學(xué)習(xí))
5.It was officially opened on March 7,1994, finally connecting Britain to the European continent.它于1994年3月7日正式開通,將英國(guó)與歐洲大陸連到了一起。
現(xiàn)在分詞 connecting 引導(dǎo)的短語(yǔ)相當(dāng)于一個(gè)并列分句。connect表示“連接”、“連結(jié)”,可與to或with連用:
This road connects the willage with/to London.
這條公路連接著這個(gè)村子與倫敦。
The lake and the canal are connected by a river.
這個(gè)湖與運(yùn)河之間由一條小河相連。

第3類條件句
(1)在第16課的語(yǔ)法中,我們學(xué)習(xí)了用第1類條件句表示將來(lái)很可能發(fā)生的事:
If you park your car in the wrong place, a traffic policeman will soon find it.
一旦你把汽車停錯(cuò)了地方,交通警便很快就會(huì)發(fā)現(xiàn)。
在第40課的語(yǔ)法中,我們學(xué)習(xí)了用第2類條件句談?wù)撓胂裰械那闆r或描寫完全不可能的事:
If you ate more and talked less, we would both enjoy our dinner!
如果你多吃點(diǎn),少說(shuō)點(diǎn),我們兩個(gè)都會(huì)吃得好的!
If I were you, I would not go to London tomorrow.
如果我是你,我明天就不去倫敦。(婉轉(zhuǎn)的建議)
(2)第3類條件句的基本結(jié)構(gòu)與前兩類都不一樣,if從句需用過(guò)去完成時(shí),主句用 would have/should have+過(guò)去分詞形式:
If it had rained, we would have stayed at home.
要是下雨,我們就會(huì)呆在家里了。
第3類條件句在if從句里設(shè)想純粹想像的事情,在主句里講述想像的結(jié)果。它與第2類條件句有一定的相似之處。但是,第3類條件句所談的是沒(méi)有或永遠(yuǎn)不可能有的結(jié)果,因?yàn)樗鼈冎傅氖沁^(guò)去沒(méi)有過(guò)的事情。它們是所謂的“假設(shè)條件句”:
If I had worked harder at school, I'd have go a better job.
要是我上學(xué)時(shí)勤奮一些,我就會(huì)有較好的工作了。(事實(shí)是現(xiàn)在的工作不太好)
在 if從句中可用 could have+過(guò)去分詞代替 had been able to +動(dòng)詞原形

suggest 有兩個(gè)意思:
1作為"暗示"意思時(shí),用法與其它的詞相同。
2作為"建議"意思時(shí),則為虛擬語(yǔ)氣,后接動(dòng)詞是要用-ing形式,后接that從句采用一種固定的用法。
should + 動(dòng)詞原形 should 可以省略
He suggested that a double railway-tunnel be built.

2表示動(dòng)作正在發(fā)生
非謂語(yǔ)動(dòng)詞中的ed形式表示其與主語(yǔ)是被動(dòng)的關(guān)系
