【记一记　➡　构建知识】(1)该句使用了“It tk+一段时间+befre+从句(一般过去时)”句型, 表示“过了一段时间后才……”。在该句型中主句谓语动词也可使用be动词。(2)It will(nt)be+时间段+befre+从句(现在时)要过一段时间后才……(用不了一段时间就……)It was(nt)+时间段+befre+从句(过去时)过了一段时间后才……(没过一段时间就……)
*It will be a lng time befre he cmes back. 要过很长时间后他才能回来。*It was nt lng befre the secnd earthquake happened. 不久第二次地震就发生了。
【悟一悟　➡　参透误区】 以上句型中若主句为将来时态, 从句则用一般现在时态; 若主句是一般过去时态或过去完成时态, 则从句用一般过去时态。
【拓展延伸】“It be+时间+从句”的句型还有: (1)It is/has been+时间段+since+一般过去时It is/has been 5 years since he came t ur schl. 这一句型可引申为: It was+时间段+since(从句用过去完成时)It was 10 years since he had arrived in China.
注意: since从句的谓语动词一般是非延续性动词, 但有时也可用延续性动词或表示状态的词, 此时需要注意句子的翻译。试比较: It is three years since she came t ur class. 她来我们班已经有三年了。It is three years since she was in ur class. 她离开我们班已经有三年了。
(2)It +was+时间点+when-clause(从句用一般过去时)It will be+时间点+when-clause(从句用一般现在时表将来)It was already eight ’clck when he came back hme. 当他回家时已经8点了。It will be midday when they get hme. 当他们到家时将是中午。

(4)It is +(high)time + that +主语+did/shuld d(虚拟语气)It is(high)time(that)we stpped/shuld stp pllutin. (5)It be +时间状语(被强调部分)+that. . . It was at 6 ’clck that we heard the nise. (强调句)
2. Over time my memry has develped s much that, like an elephant, I never frget anything I have been tld! 随着时间的推移, 我的记忆能力增强得如此之多, 就像一头大象一样, 我从来不会忘记告诉我的任何事情!

s + adj./adv.+ + adj. +a/an +单数可数名词+ + many/few/much/little(少)...+n.+that...
