雨落风残

Hello, everybody. I want to ask you a question(There is one question I'd like to ask/There is one question, the answer of which I'd like to know)

one question是单数，不能用there are,要用there is.

Please tell me, what are the differences between "look into" and "look to"

I have written an incomplete sentence.....

要用现在完成时才对，过去的过去才是过去完成时。还有incomplete是元音开头的单词，前面的冠词要用an,而不是a.

感觉你的英语表达欠准确，我按照你的意思给你改编了一下。
