Question

英文用词 ?

Answer 1

更新1:

但为何 have not 后面用的noun 要用past tense ?

更新2:

那如下意思是否一样 ? did not receive have not received.

1. Noun是不会有tense 的。只是verb会有tense 的。 2. Have not 后面 + past participle (很多时和past tense一样串法) = present perfect tense 3. Did not receive 是 past tense. 4. Have not received 是 present perfect tense. 2008-06-28 17:56:34 补充： Did not receive 当时没有收到 (at a certain time in the past) Have not received 仍没有收到 (until now) I did not receive it on Monday. I received it on Wednesday. I have already received it.
have-not 是 穷人;贫穷或缺乏资源之国家 did not = didn't 是 不能 不知道对不对，希望帮到你。
参考: Yahoo!字典
have not的意思大多是{没有}的意思
而did not 大多是解没有做的意思
所以两者就有很大的分别!have not 系没有这样东西
did not 系没有做.
have not is a present tense
did not is a past tense.
