关于强调句的疑问....

Iewily

比如PP-2-44的这题....

________until the 20th century that the magnetic compass was used for navigation.

A. Its not being

B. It was not

C. Not

D. Was not

如果像这样的题是句首空格的......如何判断这是一个强调句呢?...........

numberX

这个句子很明显缺主句的主谓啊

Iewily

可是我觉得C蛮顺的...........@_@||||||||

Iewily

或者比如这一题..........

24. ______difficult to achieve centrifugal forces thousands of times as great as the force of gravity.

A. There is not

B. While not

C. What is not

D. It is not

我当初选的是A.....然后错了........

如果去掉原句中的that，你勉强可以选C，但后面的was要提前，做部分倒装

这个....我觉得there is 后面应该接名词,这样可以理解为sth. is there.

difficult to do肯定不行了,不可能理解为difficult to do sth is there.

所以强调句型是肯定的了.it is +adj+to do sth.
