请问您几个英语问题!
尊敬的 chenjing_buaa 您好!感谢您上次回答我的问题.这次我又遇到了几个英语学习中的问题,望不吝赐教!


by the time 的用法
在这个句型中,主句一定要用完成时态吗?
by the time所引导的从句能用完成时态吗?
主句和从句的时态之间有必然的联系吗?(比如,从句一定比主句要“提早”一个时态)
It is said that Van Gogh succeeded in selling only one painting in his life,_______sold to his brother.
该空中之所以填the one而不是one 是不是因为"only"表示了one painting是特指?如果是,请问除了“only”,“the”之外,还有什么能表示特指呢?
-You' re trembling.What's happened?
-I _______out side in the cold for over an hour waiting for a bus.
A.was standing B.have been standing C.stood D.will stand
该空为什么应该填A而不是C呢?一般过去时不是也能表示“过去持续过一段时间而且在过去已经结束”的动作吗?
Seeing the blind wandering through the traffic,motorist would to step on their brakes at once.
该句首词Seeing 为什么不能改成 Having seen?
Having sent several mails to apply for jobs,Susan waited for a reply,but ______ came.
该空为什么填nothing 而不是 none?它们两个到底在指代“什么也没有”的时候到底有什么区别?


一次性问得有点多,不好意思.我把我目前仅有的5个财富值都给您啦!求指教!

1. By the time he realizes he has walked into a
trap,it'll be too late for him to do anything about it.
By the time he went abroad,he was fourteen.
看这两个例子就明白by the time相关的主从句都没有一定要用什么时态的规定,其实各种时态都有可能,只不过主句中完成时常见.
2. 英语表示特指的除了the之外,最常见的就是指示代词this/that/these/those了.It is said that Van Gogh succeeded in selling only one painting in his life,_______sold to his brother.这一句中,后面的同位结构非常明确,就是前面所说那幅only one painting in his life,所以用the one语气更加清楚.
3. -You' re trembling. What's happened?
-I _______out side in the cold for over an hour waiting for a bus.
A. was standing B.have been standing C.stood D. will stand
这个空其实填have stood outside应该也没有问题的,用现在完成时表示过去的动作stand对现在造成的影响 be trembling; 用过去进行时是强调当时的状态,比较形象.过去时的话,发生了,结束了,仅此而已.
4. Seeing the blind wandering through the traffic,motorist would step on their brakes at once.
这个现在分词表示的动作几乎是与主句动词同时发生的,所以用一般时态;如果分词动作特别明显地早于主句动词,一般会用完成时态.
5. Having sent several mails to apply for jobs, Susan waited for a reply, but ______ came.
我感觉nothing和none的区别很微妙.NOTHING = "no thing", referring to inanimate objects
NONE = "no one", referring to people, or animals 这是比较重要的一点.另一点我认为是none突出数量,而nothing突出没有这个事实或状态.请多看例句体会.
