课内探究

质疑探究：

1．But that's because I was stupid enough to play football in the rain.

但那是因为我太傻了，竟然在雨中踢足球。

(1)本句中使用了"it's/that's because＋从句(那是因为......)"句式，because(表原因)引导表语从句。

相似句式：that's why..."那是......的原因"(表结果)

That's you are too silly.那是因为你太傻。

He is ill.That's he isn't here.

他生病了，那就是他不在这儿的原因。

(2)主语＋be＋adj.＋enough＋to do sth足够......能干......

主语＋be＋not＋adj.＋enough＋to do sth不够......不能干......

You are the apple on the tree.

你不足够高够不着树上的苹果。

(3)主语＋can't/hardly/never＋be＋adj.＋enough"怎么做......也不过分"(＝can't be too＋adj.)

You when crossing the street.

＝You when crossing the street.

过马路时，你无论怎么小心也不为过。

本句为"祈使句＋and/or＋陈述句"句型。"祈使句＋and"表示祈使句与后面的句子是顺承关系，"祈使句＋or"表示祈使句与后面的句子是转折关系。祈使句相当于if引导的条件状语从句。其中"祈使句＋or＋陈述句"相当于"if＋否定条件状语从句＋主句"。

① you'll make progress every day.

(＝If you study hard，you'll make progress every day.)

好好学习，天天向上。

② ， you'll miss something important.(＝If you don't listen carefully，you'll miss something important.)认真听，否则你会漏掉一些重要
