although, so that & until

[日期:2020-06-08] 作者:外语组 次浏览 [字体: ]

 although作连词,意为虽然;尽管,同though一样引导让步状语从句,既可放在句首也可放在句中;另外,在英语中although / though不能和but同时出现在一个句子中,但它们之间可进行句型转换。如:

Although / Though Mary is thin, she’s very healthy. = Mary is very healthy although / though she is thin.

Although / Though my car is old, but it still runs very well. (×)

Although / Though my car is old, it still runs very well. (√)

My car is old, but it still runs very well. (√)

 so that作连词,意为以便,可引导目的状语从句。如:

Let’s leave now so that we can get there at one o’clock.

 until可作介词,也可作连词。

当句子为肯定句时,until表示一直到……(为止)”……之前,这时句中或主句中的动词为持续性动词。如:

Wait until 12:00 / her mother comes back.

当句子为否定句时,not ... until ... 表示 “直到…………”。如:

I didn’t finish my homework until 11:00 last night / my parents fell asleep.
