改错 Doing morning exercises are food for us?

问题描述:

改错 Doing morning exercises are food for us?

is good
但后面是问号,不知原题,

Doing morning exercises is food for us?

is good.因为此句中动名词doing...作主语,而通常非谓语动词作主语是当单数。

我来回答,habits

are ----is 主语是单数 不是看exercises

Doing morning exercises are good for us.

我觉得这句话有两个问题,首先EXERCISE当表达运动这个意思时,为不可数名词,只有在表达练习时,它才为可数的,在表达为演习时,用复数形式.所以在这里应用其原形而不是复数形式.然后就是大家所说的,ARE 应为IS

ARE改is

is good
