          [答案与精解]
        
          21. C 
        
          [注释]我怀疑那本书是否值得你去读。worth,worthy,worthwhile都含有“值得的”意思,其基本句式是:sth.be worth sth.或sth.be worth doing/be worthy of sth./be worthwhile to do sth.或doing sth.
        
          22. B 
        
          [注释]现在的导弹非常精确,可以准确击中远距离的目标。 accurate准确无误的,其名词accuracy意为“精确度”;A)exact意为“一模一样的,正好的”;C)correct正确的(仅区别对与错);D)definite明确的(旨在区别确定与不确定)。
        
          23. A 
        
          [注释]他们只知道那笔钱数额巨大,但并不清楚具体有多少。actual“实际的,真实的”,指实际存在着的事实,而非理论上存在或想像中的事情。如:the actual amount确切数目;B)real“真的,真正的”,指事物的外表符合其实际内容,而非伪造的;C)genuine“真正的”,强调正宗、地道而非冒牌的; D)apparent表面上的,显然的。
        
          24. D 
        
          [注释]科学家们正在寻找现存最古老的树,因为他们能从中了解许多东西。alive意为“活着的”,是表语形容词。作定语时置于被修饰词之后。A)live[1aiv],作形容词,只作前置定语,表示 “活的,现存的,现场的”。如:live broadcast现场直播;B)lively意为“活泼的,有生气的”;C) living意为“活着的”,多用作定语。
        
          25. D 
        
          [注释]市政府计划在5年内完成对本地经济的研究,这段时间足够进行深入而全面的研究。D)ample,A)adequate,B)enough和C)sufficient都有“足够”的意思。
        
          ①ample“充分的,富裕的”,意指绰绰有余。如:There is ample time,so you don’t have to hurry.时间很充裕,所以你不必这么匆匆忙忙的。②当只指数量时,用sufficient或enough较好,而不用adequate,因为 adequate还有“good enough适当的,足够好”的意思。试比较:The prisoners received adequate food(=good enough or enough in quantity).The prisoners received sufficient/enough food(=enough quantity).③enough“足够的”,用以修饰名词,可在名词之前或之后。它还可作副词:The room is big enough to hold a hundred people.这间房屋大得足以容纳一百人。④sufficient(足够的)和enough作形容词时意思一样,但比enough正式且不可用作副词。 Do you have sufficient books for the children? 你发给孩子们的书够了吗?
