shall, will, should, would 的用法与用法区别
will, 构成将来时，不管什么场合，都用will。
例句：I will go home tomorrow. I’ll go home tomorrow.
He will be here soon.
They will not arrive before next week.(They won’t arrive before next week.)
He won’t come today.
shall,一种用法是在主语是第一人称的句子里代 will.
例句：I shall go home tomorrow.
第二种用法，用在第二人称与第三人称的句子中，加重语气，有“非这样做不可”的意思。
例句：He shall come at once. shall是一定，非得的意思。
但现在，特别是年轻人，一般不用shall,而用 make sure.
Make sure she comes at once.
should, would,用来表达条件的助动词。
I should go at once if I were you.
I’d go at once if I were you.
I knew you’d understand.
should,应该，用于各种人称，而且只能用should。

You should see a doctor at once.
Would,行动，做法（过去的习惯）。

Would,提要求。
