Don’t be afraid of talking to me.1. afraid 是形容词,而不是动词,并且只能作表语而不能作前位定语。如:误:he afraids. / don’t afraid. / he is an afraid man.正:he is afraid . 他怕。/ don’t be afraid. 别害怕。2. 一般认为afraid 可用much 或very much, 而不用very修饰。如:he is (very) much afraid of dogs. 他很怕狗。但在现代英语也有very afraid的说法。3. afraid 一般要放在be之后作表语,而不放在 feel 之后。如:一般说i feel afraid.4. be afraid 的主语一般不能是无生命的东西。如:误:it’s afraid that we may be late. (from ****zkenglish****)正:i’m afraid (that) we may be late. 恐怕我们会迟到。5. be afraid 之后若接一个含有否定意义的从句时,其否定不能转移到主句上。(这点与hope, wish, fear 等词的用法类似,但与think, believe, suppose 等词的用法相反。)如;误:i’m not afraid that i can go.正:i’m afraid the i can’t go. 恐怕我不能去。注:省略句 i’m afraid not (恐怕不行。)也不能说成i’m not afraid. 如:a:can you do it yourself?你自己能做吗?b:i’m afraid not . (=i’m afraid that i can’t do it. )恐怕不行。展开全部
