　　时态、语态

　　(1)分析选择项中动词时态构成形式是否正确，将错误的予以排除。 e.g. What’s the matter with you You pale.

　　A. are looking B. look C. have looked D. looked e.g. I a glass while I the dinner.

　　A. broke…cooked B. broke…was cooking C. was breaking…cooked D. was breaking…was cooking

　　(2)利用标志时态的信息词。 e.g. Since then I the mail.

　　e.g. By the time you get to Beijing tomorrow, I for Shanghai.

　　A. am leaving B. shall have left C. will leave D. have already left

　　(3)时态测试的另一方面是时态一致，即主从复合句中时态配合

　　a)主句谓语动词是过去时，测试宾语从句中谓语动词的时态，依照时态一致原则判断。

　　e.g. The teacher told the children that water at 100℃.

　　A. boils B. was boiling C. boiled D. was boiled

　　a) 在由时间状语从句构成的复合句中，测试主句或者从句谓语动词的时态。从句是现在时;

　　主句必须是现在时或将来时，从句是过去时，主句必须是过去时，在包含when, as soon as, before, after, until等复合句中，如主句、从句动作发生在不同时间，先发生的用过去完成时。

　　e.g. When I see Jean in the street, she always at me.

　　A. smiled B. has never been C. had been nev D. smiles

　　e.g. As my mother here before, I had to meet her at the station.

　　A. had never been B. had been never C. has never been D. never was
