what does this mean?还是what is this mean?

this means that you need to work hard.
对以上句子 that you need to work hard 提问很明显就是
what does this mean
这句话中mean是个动词.
the meaning is that you need work hard.
对that you need to work hard 提问很明显就是
what is the meaning.
这句话meaning就是名词.
综上 what does this mean 和 what is the meaning是对的.what is thismean是不对的.mean是个动词不会有is的
