问题 As it was a small party, we need not dress up so formally.
选项 A、needed not to dress up
B、must not dress up
C、need not have dressed up
D、must not have dressed up
答案 A
解析 这是个小型聚会，我们不必穿得如此正式。本句考查。need的时态与否定形式。从As it was a small party看，题干在描述过去的事件，主从句都应该用过去时。need not说明need要用否定形式，它的过去时的否定形式有两种：needed not to和didn’t have to，选项A符合要求。选项B的must not有“禁止”之意；选项c表示“本不需要……”，多用于事后的反思；选项D的肯定形式多用于对过去事实的推测，否定式不常见。
