Question

l've got enough food and you___buy any food for our party. A.need B.don't need C.needn't to

D.don't need to

Answer 1

D
翻译：我已经买了足够的食物 你不用再为我们的派对买食物了。

因为前面说食物够了，所以后面不用买了用否定，排除A

need 作为实义动词讲时，【don't/doesn't】need to do sth

作为情态动词时，need do sth，否定形式 needn't do sth

B使用了don't 那么用了实义动词，但是后面缺少to

C needn't 用了否定形式，是情态动词，后面不能接to

Answer 2

选择第四个don't need to
因为此处need是实意动词，用法是need to do sth 必须是人做主语，所以否定就变成了don't need to

Answer 3

D
