A: Wow, what happened to you? You got fat since I last saw you.
哇，你怎么了?你比我上次见你的时候长胖了。
Get fat
长胖
举个例子：
① The trip was fun, but I got fat. We ate so well this past week.
这趟旅行很好玩，但我长胖了。我们这一周吃的超级好。
② Corey got fat. He has a big gut now. I hardly recognize him.
Corey长胖了。他现在肚子很大。我都快认不出他了。
对方口无遮拦，让你不爽，我们也不要客气，怼就是了：
B: You're not supposed to comment on people's weight. That's very rude. Don't you know that?
你不应该评论别人的体重。这很没有礼貌。你不知道吗?
两个”拿来就用“的简单实用句式：
有理有据：You're not supposed to comment on people's weight. 你不应该评论别人的体重。
得体反击：That's very rude. Don't you know that? 这很没有礼貌。你不知道吗?
如果你不想语气太重，可以说：
· That's not nice. 这样不太好。
这里有两个”句式“也很实用：
You're not supposed to…
你不应该…
举两个口语中的例子：
① You're not supposed to be here. We're closed for the night.
你不应该来这里。我们今晚不营业。
② You're not supposed to tell everyone your number.
你不应该告诉所有人你的电话号码。
另一个实用英文表达：
Comment on
评价…，评论…
在口语中的举例：
① I'm so mad. Nobody commented on my new dress.
我好生气。没人评价我的新裙子。
② Please don't comment on Gail's breakup. She's in a fragile state.
请不要评论Gail分手这件事。她现在很脆弱。
