課文詳注 Further notes on the text
1．a(chǎn) plan for a twenty-one-mile tunnel，建造一條長 21英里的隧道的計劃。
twenty－one－mile作 tunnel的修飾語，注意 mile為單數(shù)。plan for +名詞／動名詞表示“……的計劃”：
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.
他帶來了在這條河上建一座橋的計劃。
2．serve as，充當，起……的作用（也可以說 serve for）。
The books on the floor may serve as/ for a carpet.
地板上的書可充當?shù)靥河昧恕?BR> This sofa can serve as/ for(a) bed.
這張沙發(fā)可以當床用。
3．a(chǎn) better plan was put forward, 提出了一項更好的計劃。
put forward為固定短語，可分開用，其含義之一是“提出（計劃、建議等）”：
You know they wouldn't accept your plan. Why did you put it forward?
你知道他們不會接受你的計劃。你為什么要提出來呢？
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，從句的謂語動詞形式為 should（可省略）+動詞原形（cf．第63課語法）：
He suggested (that) they (should) change the plans.
他建議他們改變計劃。
suggest后面也可以跟名詞或動名詞形式。（cf．第47課詞匯學習）
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，將英國與歐洲大陸連到了一起。
現(xiàn)在分詞 connecting 引導的短語相當于一個并列分句。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村子與倫敦。
The lake and the canal are connected by a river.
這個湖與運河之間由一條小河相連。
語法 Grammar in use
第3類條件句
（1）在第16課的語法中，我們學習了用第1類條件句表示將來很可能發(fā)生的事：
If you park your car in the wrong place, a traffic policeman will soon find it.
一旦你把汽車停錯了地方，交通警便很快就會發(fā)現(xiàn)。
在第40課的語法中，我們學習了用第2類條件句談論想像中的情況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，少說點，我們兩個都會吃得好的！
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從句需用過去完成時，主句用 would have/should have+過去分詞形式：
If it had rained, we would have stayed at home.
要是下雨，我們就會呆在家里了。
第3類條件句在if從句里設想純粹想像的事情，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有或永遠不可能有的結(jié)果，因為它們指的是過去沒有過的事情。它們是所謂的“假設條件句”：
If I had worked harder at school, I'd have go a better job.
要是我上學時勤奮一些，我就會有較好的工作了。（事實是現(xiàn)在的工作不太好）
在 if從句中可用 could have+過去分詞代替 had been able to +動詞原形:
Why didn't you read the book yesterday?
你昨天為什么沒有看這本書?
I'd have read it if I could have bought it!
如果咋夭我能買到這書我就會讀的!
