提一些英语问题It's twenty years he came to work in this school.A.that B.since 答案是B,为什没不选A?Stephen Hawking stressed to the interviews that his accomplishments would certainty have been achieved by others, A.never had he lived B.had he never lived C.he had never lived D.never had he lived为什么选B?这句话又如何翻译?Little i known when i took the trip where it could lead me.为什么用did不用had?He did not teach himself to paint he was in his twenties.这是一道填词题,我写的是before,答案是until ,不

1.如果选A的话，这句话就是一个强调句型，强调句型的一个判断有一个小窍门，去掉 it is和that，如果成分仍齐全，那么就是一个强调句型，这道题如果是强调句型，就是twenty years he came to work in this school.自然不完整。
2。这是一个虚拟语气，had he never lived 就是这句话的假设句。因为假设在过去，所以用的过去完成并将had 提前，这样翻译：Stephen Hawking 强调：如果他没有活下来的话，他的成就完全可以由别人取得。
3。Little i known when i took the trip where it could lead me.为什么用did不用had？不知道是题目有问题还是你不小心打错了，我觉得不应该是known,而应该是know. know的话，就选did了，little did i know应该可以算作一个固定搭配吧。
4。不可以。not until 是一个固定搭配，意为直到什么才。这样翻译：他知道二十岁才自学画画。
5。主从句时态应该保持一致，前面主句用的是一般过去时，所以后面从句也得用一般过去时了，用had.

B.since
这是个时间状语从句，since可以当引导词
that不可以充当时间状语从句的引导词
B.had he never lived
这是虚拟语气的省略形式，完整的是if he had never lived如果他没来到这个世上
这句话的意思是：霍金在采访中强调，如果没有他，他的那些成就也会被别人取得
He did not teach himself to paint he was in his twenties.
可以用before
not…until句型可与before互换用，但在强调句中一般仍用until。
An idea suddenly floated into the weeping sailor's mind that he really an appetite
时态要保持一致
