not until/until的用法區(qū)別

not until/until兩者皆可接延續(xù)性動詞和暫短性動詞.

一、not...until指的是“直到...才”的意思,如 I did not go home until my mother called me.

我直到我媽媽打電話給我才回家.

not until的倒裝與強調(diào)結(jié)構(gòu)

1.當Not until位于句首時,句子要倒裝.其結(jié)構(gòu)為:Not until+從句/表時間的詞+助動詞+(主句)主語+謂語+.如:

①Not until the teacher came in did the students stop talking.直到老師進來學生們才停止講話.

②Not until next week will the sports meet be held.直到下周才開運動會.

2. not until的強調(diào)結(jié)構(gòu)為:It is / was not until+從句/表時間的詞+that+.

上面兩句改為強調(diào)句為:

③It was not until the teacher came in that the students stopped talking.

④It is not until next week that the sports meet will be held.

直到我結(jié)婚的時候,我才有錢買了自己的房子.

It was not until I got married that I could afford to buy a house of my own.

而until指“直到”.例如：

Go alone the street until you see the traffic light.

往前走,直到你看見交通燈.
