(2)探究新知:
although,so that和until引导的状语从句
① although引导的让步状语从句:
Although he is poor,he is very happy.
She ate two moon cakes althouhg she isn’t hungry.
ahthough 是一个连词,意思是________.既可以放在______, 也可放在_________.
② although不能与____在同一个句子中连用,但可与副词still,yet等连用。
例如:
Though it was raining hard, but he still went out.(×)
改为:Though it was raining hard, he still went out.
或: It was raining hard, but he still went out.
2、so that的用法
so that也为从属连词,意为“以便;为了”,相当于in order that,引导目的状语从句,通常放在主从句之间,一般不用逗号隔开。此时,从句中的谓语常使用can,dould,may,might,would,should等情态动词。当主句和从句的主语一致时,可以用in order to将复合句改为简单句。
e.g.I got up early this morning so that/in order that I could catch the first bus.
= I got up early this morning in order to catch the first bus.
今天早上我起得早,以便赶上首班公共汽车。
3、until引导时间状语从句
Until意为“直到……”。引导时间状语从句。用于肯定句时,主句的动作必须是延续性的,表示这一动作或状态一直延续到until所表示的时间为止;用于否定句时,主句的动作一般是非延续性的,强调表示的状态或情景直到until所表示的时间才发生,构成not…until…结构,表示“直到…才…”。如果主句使用一般将来时,则从句必须用一般现在时表示将来。
