I am afraid to write english compositions,because i afraid o

e afraid of doing sth.唯恐（生怕）做某事
be afraid to do sth.不敢做某事
I'm afraid to ride the bicycle because I'm afraid of falling off it.
我不敢骑单车,因为我生怕从车上摔下来.
再问： because i am afraid of writing it wrong. 后面一句因为我害怕写错，你的意思，it放后面?
再答： 我觉得你这句的正确表述是： I am afraid to write English compositions, because I am afraid of writing them wrongly. afraid前应有be动词，them指代English compositions，wrongly修饰动词writing。
