英语语法问题？？？？

Question

Let’s ______ about the karaoke contest. Hey, how about having a picnic at the park today?
(A) don't talk
(B) not talking
(C) not talk
(D) not to talk
答案是什么？求解释
谢谢

Answer 1

选C。这里考的是一个固定搭配，“Let's do sth”即“让我们一起去做…”，其否定形式为“Let's not do sth”，直接在动词原形前面加“not”就好了。
因此这里套用搭配就是“Let's not talk about the…”

Answer 2

C

let sb do sth 让某人做某事，其否定形式为：let sb no do sth. 让某人不做某事，故选C。
考点：动词不定式的否定。本回答被提问者采纳

Answer 3

选择C，let sb do sth. 或者 let sb not do sth.
如果用don't的话，应该是 don't let sb do sth.表示不要让某人做某事

Answer 4

答案选c,lets sb do sth, lets sb not do sth,固定搭配

Answer 5

选C
let sb do sth
否定格式 let sb not do sth
