what is the difference between have eaten & ate?
鬼貓发表于 2011-10-7 03:07 PM

have eaten = （现在）吃了
ate = （过去）吃
两者说的可以是同一个动作，have eaten 强调的是某个动作已完成，ate表达的只是过去的一个动作。

发现不少本地人开始“传播”一个莫名其妙的语法，比如说“我吃了”，他们会说“I had eaten”，他们的解释是：是过去吃的，所以得用过去的 had，这是错误的理解。
have eaten 针对的时间是现在，所以 have 必须是现在时的：
I have eaten breakfast. 我（现在）吃了早餐。

当过去完成的那个动作和现在的状况还有关联时，我们通常会用 have + （过去分词/past participle)来表达：
I'm not hungry. I have just eaten a bowl of noodles. 我不饿。我刚吃了一碗面。
I can find my wallet. I have lost it. 我找不到我的皮包。我把它丢失了。
The rain has stopped. We can go out now. 雨停了。我们可以出去了。

英文分得太详细了。
for example, if someone asks me
friend: Did you eat ?
Me: Yes, I ate. (Here we can't use Yes, I have eaten.)

Or

friend; Have you eaten?
Me:Yes, I have eaten just now.(Then here can use have eaten) depend on sentence.

Additional Information: the book i ever studied says past tense come with specified and clear time for example yesterday and so on. Past participle comes with unknown and unspecified time.

这句话应该是我说的才对。

This is the sentence i see is in drama. But, i don't know how to use it "should be say+ing" or "should be verb+ing'. Thank you in advance.

I am quite confused with the words " could" and " would".
I know they are past tense of can and will. But sometimes i see they are used like this. For example:

1. You don't be afraid. I would protect you. ( Why here is using would not will, if i use will can or not?)

same with the word "could".

can, could, will, would 等都是情态助动词 modal auxiliary verb，用法的确比较复杂，比如说 can 和 could，有时候是现在和过去的分别，有时候不是时间的分别而是确定程度的分别--can 比 could 更为确定，因此有些场合使用 could 的话就可以显得不那么确定而较为婉转，所以我们常说用could 取代 can 会显得更有礼貌。

You don't be afraid 语法上是不正确的，应该是：Don't be afraid. 这种句子是祈使句/imperative
would 常用在条件式句子，如：If I were you, I would apologize to her.

如果你那句想表达的是：I would protect you if I could. 就没问题；但如果你想说“我愿意保护你”，那应该说：I'll protect you.
I'll 用于表达个人的意愿，如：
（电话响了）I'll answer it.
（看到有人手上拿了很多东西，不方便开么）I'll open the door for you.
