4. D. 因?yàn)閞equirement后的表語(yǔ)從句的謂語(yǔ)要用“(should +)動(dòng)詞原形”；material(材料)與heat(加熱)是被動(dòng)關(guān)系，用被動(dòng)語(yǔ)態(tài)，所以是be heated。

5. D. 因?yàn)閣ish后的賓語(yǔ)從句中的謂語(yǔ)動(dòng)詞要用過(guò)去式，此題的study business是與過(guò)去事實(shí)相反的情況，所以用had studied business(from www.hz123456.com)。

6. C. 因?yàn)橹髡Z(yǔ)是demand時(shí)，其后的表語(yǔ)從句的謂語(yǔ)要用“(should +)動(dòng)詞原形”。

7. C. 因?yàn)榫渲衞therwise (否則)表示與過(guò)去事實(shí)相反的情況，所以用would have done。

8. D. 因?yàn)榻樵~短語(yǔ)without…表示與現(xiàn)在事實(shí)相反的情況，所以用would be。

9. B. 由had not gone可知，條件句是與過(guò)去事實(shí)相反的情況，而now提示我們，主句是與現(xiàn)在事實(shí)相反的情況，所以用would be。

10. D. 因?yàn)閕f only (要是…就要了) 其后的句子要用過(guò)去式表示虛擬語(yǔ)氣，由as you do可知，是與現(xiàn)在事實(shí)相反，所以選knew。

11. A. 因?yàn)閎ut for (要不是因?yàn)椤⑷绻麤]有) 通常要與虛擬語(yǔ)氣連用，由fifteen years ago可知，這是與過(guò)去事實(shí)相反的情況，所以選would have died(from www.hz123456.com)。

12. A. 因?yàn)閣ould come earlier是與過(guò)去事實(shí)相反的虛擬語(yǔ)氣，而后面分句表示的是事實(shí)：當(dāng)時(shí)我的確不知道…所以用一般過(guò)去時(shí)，選A。

13. C. 因?yàn)閠hat從句是suggestion的同位語(yǔ)，應(yīng)當(dāng)用“(should+) 動(dòng)詞原形”表示虛擬語(yǔ)氣，又因the students與give是被動(dòng)關(guān)系，所以選be given。

14. A. 因?yàn)閃ang Ling是中國(guó)人的名字，顯然不是英國(guó)人，所以as if從句的謂語(yǔ)要用與現(xiàn)在事實(shí)相反的情況，所以用were。

15. A. 因?yàn)?/SPAN>had it not been for the policeman = if it had not been for the policeman (如果沒有警察) ，顯然是與過(guò)去事實(shí)相反的情況，主句中的謂語(yǔ)應(yīng)是would have lost。

16. B. 因?yàn)橛芍骶渲^語(yǔ)可判斷，表示的是與過(guò)去事實(shí)相反的情況，所以虛擬條件句中的謂語(yǔ)應(yīng)用過(guò)去完成時(shí)，Had the captain been = If the captain had been。

17. A. 由于從句謂語(yǔ)為一般過(guò)去時(shí)，表示的是對(duì)現(xiàn)在的虛擬，故主句謂語(yǔ)用過(guò)去將來(lái)時(shí)，表示。Were it not for the snowy weather=If it were not for the snowy weather.

18. B。這是個(gè)錯(cuò)綜時(shí)間虛擬條件句：主句與現(xiàn)在事實(shí)相反，條件句與過(guò)去事實(shí)相反。句意為“如果我不是在七歲時(shí)就迷上了Melinda Cox 圖書館，我真不能想象我如今會(huì)在做什么”。

19. D。本題考查目標(biāo)與1996上海同。由otherwise和hesitated可知，這是與過(guò)去事實(shí)相反的虛擬語(yǔ)氣，謂語(yǔ)動(dòng)詞用 would+ have+ 過(guò)去分詞構(gòu)成(from www.hz123456.com)。

20. B。wish 后面賓語(yǔ)從句的謂語(yǔ)總是用過(guò)去時(shí)態(tài)。此題是表示與現(xiàn)在事實(shí)相反的愿望，從句謂語(yǔ)用一般過(guò)去時(shí)。句意為“我多么希望每個(gè)家庭都有座有一個(gè)漂亮花園的大房子啊！”
