3. B. at that time表示過去的一點(diǎn)時(shí)間
4. B. from ten to twelve last night表示過去的一段時(shí)間
5. A. last night與過去進(jìn)行時(shí)連用，說明動(dòng)作還沒有結(jié)束 。B,C,D時(shí)態(tài)、語態(tài)不合題意,所以，選A.
6. B. 上下文聯(lián)系，過去正在進(jìn)行。非延續(xù)性的動(dòng)詞用進(jìn)行時(shí)表示狀態(tài)。
7. C. 上下文聯(lián)系，過去正在進(jìn)行。
8. D. 上下文聯(lián)系，過去正在進(jìn)行
9. D. at ten yesterday evening表示過去的一點(diǎn)時(shí)間
10. B. 主句用過去時(shí)，從用相應(yīng)的過去時(shí)，所以選B.
11. A. 上下文聯(lián)系，過去正在進(jìn)行
12. B. 主句的動(dòng)作先發(fā)生，并且是延續(xù)性的動(dòng)詞， 主句用過去正在進(jìn)行時(shí)，從句用
“一般過去時(shí)態(tài)
13. D. 主句的動(dòng)作先發(fā)生，并且是延續(xù)性的動(dòng)詞， 主句用過去正在進(jìn)行時(shí)，從句用
“一般過去時(shí)態(tài)”
14. A. 主句的動(dòng)作先發(fā)生，并且是延續(xù)性的動(dòng)詞， 主句用過去正在進(jìn)行時(shí)，從句用
“一般過去時(shí)態(tài)”
15. A. 從句的動(dòng)作先發(fā)生，并且是延續(xù)性的動(dòng)詞， 主句用“一般過去時(shí)態(tài)”，從句用
過去正在進(jìn)行時(shí)
16. B. 從句的動(dòng)作先發(fā)生，并且是延續(xù)性的動(dòng)詞， 主句用“一般過去時(shí)態(tài)”，從句用
過去正在進(jìn)行時(shí)
17. A. be(was, were ) + when .....表示when后面的動(dòng)作突然發(fā)生。其實(shí)when在這里是并列連詞， 而非從屬連詞。
18. B. 從句的動(dòng)作先發(fā)生，并且是延續(xù)性的動(dòng)詞， 主句用“一般過去時(shí)態(tài)”，從句用
過去正在進(jìn)行時(shí)
19. C. 從句的動(dòng)作先發(fā)生，并且是延續(xù)性的動(dòng)詞， 主句用“一般過去時(shí)態(tài)”，從句用
過去正在進(jìn)行時(shí)
20. C. 如果主、從句的動(dòng)作發(fā)生沒有先、后關(guān)系，這時(shí)，主、從句用“一般過去時(shí)態(tài)”。但如果主，從句的動(dòng)作同時(shí)發(fā)生，并且是延續(xù)性的動(dòng)詞，常用while連接主、從句。主、從句謂語動(dòng)詞都用過去進(jìn)行時(shí)態(tài).
