8．-I'll have nothing to wear to work on Monday ______ I pick up my clothes at dry cleaners'．
-Then you'd better hurry．It closes at noon on Sundays．（　　）

A．

though

B．

C．

unless

D．

after

分析 ---如果我不去干洗店拿衣服，周一我就沒有衣服可以穿著去上班了．
---那你最好快點．干洗店在每周日中午就關門了．

解答答案：C．根據(jù)-I'll have nothing to wear to work on Monday （周一我就沒有衣服可以穿著去上班了）和I pick up my clothes at dry cleaners'（我去干洗店拿衣服）可知如果我不去干洗店拿衣服，周一我就沒有衣服可以穿著去上班了．所以選擇C unless"除非，如果不"．其他選項的含義分別是A"雖然"；B"隨著，因為"；D"在…之后"．

點評考查從屬連詞．
unless是從屬連詞，引導條件狀語從句，含有否定意義，相當于if條件狀語從句的否定形式．所以unless=if not．注意：unless引導的條件狀語從句和if條件狀語從句，與其它時間狀語從句一樣，用一般現(xiàn)在時代替將來時
