Part II Language Knowledge (45 marks)
Section A (15 marks) Directions: For each of the following unfinished sentences there are four choices marked A, B, C and D. Choose the one that best completes the sentence.
21. When _____ with prices of goods, the quality of the goods has to be taken into consideration.
A. compared B. comparing C. to compare D. being compared
【答案】A
【解析】考查非谓语动词。本句中的动词compare与句子主语the quality of the goods构成逻辑上的被动关系，所以使用过去分词compared。同时状语从句的主语the quality of the goods和系动词is都被省略了。句意：当与商品的价格相比，商品的质量不不得不被考虑在内。故A正确。
22. We were delayed at the airport. Otherwise, we_______ here by lunch time.
A. must be B. must have been C. would be D. would have been
【答案】D
【解析】考查虚拟语气。本题考查的是含蓄条件句，通过副词otherwise否则，要不然表示条件。Otherwise="If" we had not been delayed at the airport。根据前面的were表示与过去事实相反，所以主句中使用“情态动词+have done”。句意：我们在机场被延误了。要不然，我们就会在午饭之前到达这里。故D正确。
23 ____once a year by fire officials, whether a school is large of small, is a regulation that must be carried out in this country.
A. Inspected B. Being inspected C. Inspecting D. Having been inspected
