大家好！我有一些问题。 第一个：How to say: "You think right / You are right"? 你觉得对 — is it the right way to say that? 第二个：What is the difference between: 穿了，穿上了，穿着 第三个：How to use 了 if speaking about one action before the other?我做了饭以后，去看她了 — Am I right? 第四个："把这个题目说明给我" the right one? I want to say: Explain this topic to me. Thank you in advance! 1.You think right / You are right"? 你觉得是对的/你是对的 2. 穿了=穿上了 ...have already put on it. 穿着=wear or put on, It's verb in Chinese. e.g. 我穿著一件毛衣 I wear a sweater. 3. We always use 了 to describe something have been done. e.g. 我的錢包不見了 My wallet have gone. 太陽下山了 The sun have set. 我做了饭以后，去看她了 — Am I right? -> You are right, but it would be better to amend this sentence to "我做完饭以后，去看她了" 4.Explain this topic to me.-> 幫我解釋這個題目 (question). In Chinese, Topic is 主題. It's like a title of an article or a certain issue. question is 題目.

第一个：你想得对。/你是对的。 第二个：“穿了/穿上了"强调动作（put on)，"穿着”强调状态(be in)。 第三个：“了”的用法，你的理解是对的。 第四个：给我解释一下这个题目。不过这样说话是很生硬的，所以实际会这样说：给我解释（一）下这个题目吧。/请给我解释（一）下这个题目吧。

-Do you think this is right? -你觉得这对吗？ -穿了indicates the completion of the action of 穿. 穿上了has the same usage but with a much shorter time frame. -穿着is used to say what I'm wearing at the exact point in time. -我做了饭之后，去看她了。 -Please explain this to me. -请给我解释一下（这个）

No.1: 你是对的/你是正确的 No.2: Actually,we can say that they are the same meaning.For example:我穿了棉袄/我穿上了棉袄/我穿着棉袄 is the same meaning. No.3:了 is a statement label designator ,expressing the past tense.我做了饭以后，去看她了 is right. No.4:You are right.

@ Paul Hello, how are you?
