英语翻译1 骑黑色自行车的那个男孩是李蕾 2 穿红色上衣的那个妇女是我的母亲

我是一个英语老师,据我判断你是想要“定语”的那部分,并且很可能想要定语从句.此处可用三种作定语：
(1)定语从句,（2）现在分词短语 （3）介词短语
1.The boy who/that is on the black bike is Lilei.
The boy who/that is riding a black bike is Lilei.
The boy on the black bike is Lilei.

2.The woman who/that is in a red coat is my mother.
The woman who/that is wearing a red coat is my mother.
The woman in a red coat is my mother.

The boy on the black bicycle is Li Lei.
The woman in the red coat is my mother.

the question is very easy.you should learn : ... is ... and know how to translate "骑黑色自行车”and “穿红色上衣”
that's all.

还是简单点的好：

2) That woman who is on red coat is my mother.
