·本課句型

if真實條件句(假設(shè)過去)

1.If 從句為過去的各種時態(tài)

????·be 動詞必須用 were，但根據(jù)《牛津英語用法指南》第四版來看的話，虛擬語氣的 were 變得不如以前常用

2.主句為過去將來時????could/would/should/might + do

????·The tunnel would be well-ventilated if tall chimneys were built above sea level.????假設(shè)煙囪過去被，是能成真的

????·This would solve the problem of ventilation, for if a train entered this tunnel, it would draw in fresh air behind it.

if虛擬條件句(假設(shè)過去)

1.If 從句為過去完成時????had done

2.主句為現(xiàn)在完成時 could/would/should/might + have done

????·If, at the time, the British had not feared invasion, it would have been completed.?

????????·本句運(yùn)用了被動語態(tài)，it would have been completed，它早就被建成了，它指隧道，隧道不會自己建成，所以要運(yùn)用現(xiàn)在完成時被動語態(tài) have been

????·Years ago if someone had turned round to me and said “in two years you’ll be England

captain”, I would have turned round and said "I don’t think so!”

練習(xí)，根據(jù)真實句寫出虛擬句

賓語從句的虛擬

He?suggested that?a double railway-tunne?should be?built.

????·suggest?表示“建議”，其后賓語從句要虛擬，如果不是虛擬語氣，就有我的這個建議你一定要把它弄成真的，有壓迫感。從句中謂語動詞 = (should) + 動詞原型

????????·suggest, advise, propose, recommend/order/ask, demand, insist, request ...

·課文

????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.
