初一英语!改错The woman with two children are teaching herself Chin

1.The woman with two children are teaching herself Chinese.
把are改成is.这里是伴随状语,若主语是单数则动词就是单数形式.
2.How important it is to careful with fire!
How important it is to be careful with fire!要+be动词的.
3.I often write to him when I was in Japan.
I often wrote to him when I was in Japan.
或者是I often write to him when I am in Japan.
或者是I used to write to him when I was in Japan.

第一题把are改为is ,因为"The woman"是主语,单数.
第二题在to 后面加be,因为to 后面不能直接加形容词.
第三题把write 改为wrote,因为后面的状语从句when...是一般过去时.

1 are 改 is
2 to 去掉
3 write 改为 wrote
