B
当 need 为情态动词时,后直接跟动词原形,所以用: needn't worry about 没有必要担心
当 need 为实意动词时,应该用: don't need to worry about your study 没有必要担心你的学习
祝你学习进步,更上一层楼! (*^__^*)
不明白的再问哟,请及时采纳,多谢!

选B

用needn't
首先这里的意思是要表达无需担忧,所以D就被排除了。
如果Need作实义动词用,应该用don't need to worry about,但是没有这个选项
所以这里的need是情态动词,情态动词后面直接接动词,所以用needn't worry about
请采纳!

选B
need当情态动词用,直接加not否定,后面动词用原形
A用don't否定,说明need当实义动词用,此时后面要用to do
C 情态用法加to,明显错误
D 逻辑提示,后面说“我们会帮你”,所以应该是“不必担心”
