1。我觉得it is 在这里是一个强调句的省略 完整的应该是it is the children who is making so much noise outside。2.LiMing speaks English well even if he didn't go abroad. 3.疑问句：“ what was the matter ？” The teacher asked when he saw a girl crying suddenly. 陈述句：The teacher asked what was the matter when he saw a girl crying suddenly。这个应该就可以把 最后一个我不太确定 希望能帮到你的忙
1：children是复数的不可数形式。。（谁正在外面制造这么多噪音? 是孩子.）2：LiMing 把英语说得很好虽然他没有出国。和LiMing 把英语说得很好即使他没有出国。两个句子句意略有不同。。。3.疑问句：“ what was the matter ？” The teacher asked when he saw a girl crying suddenly. 陈述句：The teacher asked what was the matter when he saw a girl crying suddenly。这个应该就可以把 最后一个我不太确定 希望能帮到你的忙
