这个句子 You needn't be worried about it. 完全正确,一点问题都没有。

1. 既然 needn't do 正确,needn't be 肯定正确。

2. worry about it 和 be worried about it,都对。前者强调动作,后者表示状态。

need 可以是情态动词,也可以是实意动词。作为情态动词,need只用于否定和疑问句,不能用于肯定句。因此need用于否定句时,可以有二种用法,实意动词用法和情态动词用法。

You needn't do it.

You don't need to do it.

You needn't be there.

You don't need to be there.

网友既然见过第一和第二句的用法,就应该知道第三种用法无疑是正确的,只不过实意动词为系动词而已。情态动词need后接不带to的不定式,实意动词need后接带to的不定式,或者直接接名词。只要记住情态动词need不能用于肯定句即可。如下句为错误:

You need come tomorrow. 应改为to come。

You need be here tomorrow. 应改为to be。

否定句则不受限制。
