易错句子He goes to the gym every day to keep bod in shape.

正确表达He goes to the gym every day to keep his bod in shape.

bod 是可数单数名词，指某个人的身体时前面必须有限定词。汉语“保持身材”里不出现物主代词，直译时就会漏掉 his；补上物主代词 his 后句子才合语法。

易错句子Two bod were waiting outside the gym.

正确表达Two bods were waiting outside the gym.

bod 是可数名词，被 two 这类数词修饰时要用复数形式 bods。汉语名词没有单复数变化，所以容易漏掉词尾 -s。

易错句子She does yoga every morning, so she has a health bod.

正确表达She does yoga every morning, so she has a healthy bod.

修饰名词 bod 必须用形容词 healthy，而 health 是名词，不能这样作定语。汉语“健康的身体”中的“健康”兼作名词和形容词，迁移过来就误用了 health。
