Question

It's windy-------autumn in Nanjing.是in、at、on、of
还有.I------buy a new watch.是don't need don't need to needn't to needs
能解释一下为什么这么做的原因,翻译整个句子.

Answer 1

1,It's windy 【in 】autumn in Nanjing.
南京的秋天有风.
在某个季节 用 介词 in .
2,填 don't need to
need 作实意动词时,否定句需要加助动词 do ,后面跟不定式 need to do sth
need 作情态动词时,否定句直接在 need 后面加 not ,构成 needn't ,后面跟动词原形,needn't do sth
句意是：我不需要买新手表.
