在线问og73 if从句中would和should

cissy

有一点点理解了！也就是说would 比较强调说话人本身有这个意愿，但是往往这个意愿是达不到的，而should 则是个人意愿的色彩比较少，是不是啊！

我不知道“should 则是个人意愿的色彩比较少”对不对

哪位nn谁来帮我们看看？

would和should虽然都在虚拟句里，但关键是位置有区别啊．if 后面都是跟should,或were,v+ed,没有would的说法吧．而主句中则可以用should would might等等．

guandream

the whole sentence uses past tense, if verb in" if clause"  uses "would", it is a  past tense form of "will", so this sentence is wrong.

我倒是看到有另外一种解释：should的用法
Used to express conditionality or contingency:
用于表示可能性或可能发生的事件：
If she should fall, then so would I.
如果她失败了，那我也会失败

the whole sentence uses past tense, "would" in if clause is the past form of "will", otherwise, the meaning of the sentence is unclear. in if clause "will or would" cannot be used .

if 后面可以跟would 啊，看看下面的例子：
张道真语法摘录：（if条件句中）过去时表示一个与现在或将来相反的假想情况
                              if he knew it, he would tell me
                              表示将来的也可用were+不定式
                              if she were to love him, she would marry him
                              虚拟将来时态，可用should
                              if she should know it , she will(would) tell me
                表示某种愿望，但是说话人不相信此愿望能实现，不相信主语有此愿望，用would
                 if he would pay me, we would be friends again

thornbirdcfa

I mean: "would" is usually not placed just behind the if clause---"if he knew it" "if she were to love him" "if she should know it "   ,but in the main clause "he would tell me""she would marry him"
only this is special:if he would pay me, we would be friends again不相信此愿望能实现
I'm right? should be.....

那thornbirdcfa的意思就是说，在if 从句里一般跟should 极少跟would，主句里倒是用would比较多是吗？

gemj，sbbi快过来看看啊！

That's my opinion. Actually you better chech out the grammar books about the 虚拟句.  
have you ever seen the "would" placed right in the if clause? (I mean not the main clause)   check it out.
