Okay, now let's learn some words to describe body shape and size. You already know the basic words fat and thin – but there are many other ways to say these.
好，那我们现在就来学习一些用来描述身材的单词。你们肯定已经知道了诸如fat、thin这样的入门级词汇，不过还有很多种描述方法。

A person who is fat can also be described as overweight, heavy, big, or large. The word for a person who is EXTREMELY fat is obese.
胖还可以用overweight、heavy、big和large来表达。用来说一个人胖到极点的词是obese。

We also have the word chubby to describe fat children; husky or heavyset to describe fat men; and plump or curvy to describe fat women (the word curvy has a more positive connotation, implying that the woman has a nice, full, feminine body).
用来说小朋友比较胖的词可以是chubby；肥胖的男性可以说成husky和heavyset；丰满的女性则用plump和curvy来表达（curvy的含义更积极，意指女性的身材很好很饱满，很有女人味）。

If you want to say a specific part of the body is fat, you can say it is flabby –for example, “I hate my flabby stomach.”(typically used for arms, stomach, thighs, and butt).
如果你想说身体的某一个特定部位比较胖，你可以用flabby——比如，你可以说“我太讨厌我肉肉的肚子啦！”（这个词一般可以用于胳膊、肚腩、大腿、臀部等部位）。
