英语语法打卡

英语语法打卡第9天：

四原因状语从句
1.引导原因状语从句(Adverbial Clause of Cause
)的连词或复合连询 because,as,c, for now
that, in that, seeing that, considering that, on the ground(s) that
BecauseSinceAs the weather is so bad, we have to delay our journey.因为天气很差,我们不得不推迟旅程。(主句前不可同时用so)
She disliked him on the grounds) that he is lazy.因为他懒,所以她不喜欢他
A gas differs from solid in that it has no definite shape.
气体不同于固体的地方就在于它没有
定的形状。
【专四真题】 Barry had an advantage over his mother
he could speak French.
A. since that
B.in that
. at that
D. so that
译文:巴里比他母亲强的一点在于他能讲法语。
分析: in that为固定词组,表示“既然,因为”,可引导原因状语从句,因此选项B正确。A项中的 since也有“既然,由于”的意思,但一般不接that
----------------------
2. because, since,as和for表示原因时的区别:
● because, since,as表示因果关系语气由强到弱,在强调句式中,若强调原因状语从句,只能用be
cause引导;
●for引导的分句只是对前面分句加以解释,说明推断的理由,并且只能后置。
It was because he was late that he didnt' go with us.正因为他来晚了,才没有和我们一道去。(because不可以换成 since或as)
The fuel must have been finished, for the engine stopped.燃料一定是用完了,因为发动机停了。3.not. because否定 because引导的从句
在由 because引导的主从复合句中,如果主句中含有否定词not,则可能是否定 because引导的从句如 She didn't' marry you because you had money.= She married you not because you had money她嫁给你,不是因为你有钱
The mountain is not famous because it is high. The mountain is famous not because it ishigh.这山有名,并不是因为它的高度。
