the right forms of the words与the right form of the words
1个回答

有区别.

第二句是指那些 words 的唯一的正确格式,

而第一句意味那些 words 有数个不同的正确格式.

用哪个要看句意的需求.

例句:

The right form of expressing sympathy to someone is to say "I'm so sorry to hear that".

The right forms of greeting someone you meet on the street are:

Good morning!

How are you?

Hello!

How's it going?
