露西数学学得不好用英语怎么说
错了…DoSe为什么不用is
问题补充后我的修改答案
因为mean是行为动词,提问时必须用助动词 do/does/did ,因为是单三,用does
你问为什么不用is 告诉你如果这样表达就可以了:What is the meaning of this word? 这里的meaning就是名词了
Lucy doesn't do well in Math=Lucy is not good at Math.
希望能帮到你 。但愿我解释的你能明白追问

be good at 不是擅长的意思吗为什么用be good at。顺便再帮我回答3个问题吧mary made some cake yesterday怎么改为否定句?mary()()()cake yesterday。另一题是they played football yesterday morning改为一般疑问句,是否是这样改:Did they play football yesterday morning。还有一道是His mother could perform ballet when she was young对perform ballet提问()()his mother ()when she was young
追答亲,be good at 是固定搭配哦 相当于 do well in 就是擅长,善于
好的~
1.变否定句 Mary didn't make any(一定记得在否定句中some 变为any)cake yesterday.
2.正确!~
3.What could his mother do when she was young?
解答完毕,看你是否还有疑问
那啥我英语不行...你QQ多少,以后不懂得直接问你吧...

WHAT,作主语后面必须用动词单三形式,如果用the那么就缺少动词,所以不能用the。lucy is not good at math 。 因为缺少动词 用does代替动词 而is不能作代词
