●答案與解析●

1. C。先行詞是地點名詞，定語從句中又缺地點狀語，用關(guān)系副詞 where。

2. D。關(guān)系代詞 which 代替 Carol 所說的話。句意為：Carol 說這工作將在十月完成，我本人對此表示懷疑。

3. B。關(guān)系代詞 which 代表前面整個主句，在定語從句中作主語。of course 為插入語，做題時可略去不看。

4. B。關(guān)系代詞 as 代表整個主句，在定語從句中作主語。

5. C。先行詞是表示時間的詞 the hours，并在定語從句中作狀語，因此選關(guān)系副詞 when。定語從句與先行詞被 back to me 分開。

6. B。as 在定語從句中代表主句。意為“正如…”，它引導(dǎo)的定語從句既可放在主句前，也可放在主句后。which 也可以代表主句，意為“這 / 那件事…”，但它引導(dǎo)的定語從句只能放在主句的后面。

7. D。on 不表鐘點；by 指時間“到那時為止”。句意為“在辦公室里，我似乎直到下午5:30才有空，那時，許多人都已回到家?！?/span>

8. C。先行詞是 those(指 those flowers)。they once grew 前省略了關(guān)系代詞 which。副詞 once 要放在行為動詞前。句意為：這兒所養(yǎng)的花是由他們曾在森林里種植的花培養(yǎng)出來的。

9. A。答案中的“I think”是插入語，如果將其去掉，便可清楚地看出答案。另外，which 在題中引導(dǎo)一個非限制性定語從句，并在從句中作主語。

10. D。關(guān)系代詞which在此用用于引導(dǎo)非限制性定語從句。

11. B。表示先行詞所表示的“那個人或物的…”用 whose…或the…of which=of which…。因此，表示 “花瓶的價格” 可說 the price of which 或 of which the price 或 whose price。另外，若在 its price 前加 and 也對。

12. A。先行詞是 situation，指地點位置，用 where(=in which)引導(dǎo)定語從句。

13. D。先行詞是 many cases，定語從句中缺狀語(in many cases在許多情況下)，用 where (=in which)引導(dǎo)定語從句。

14. B。tell sb about…把有關(guān)…的情況告訴某人。

15. D。這是非限制性定語從句，先行詞是 moment，關(guān)系詞在從句中作狀語，用 when。

16. C。which 代表整個主句，在定語從句中作 hadn’t expected 的賓語。

17. C。whose 在定語從句中用作定語。

18.C。關(guān)系代詞 which，代表 John 所說之事，在定語從句中作主語。which = and that / this / it。

19. A。the reason 后接定語從句。因為代表先行詞 the reason 的關(guān)系代詞 that / which 作 explained 的賓語，所以被省略了。注意與 the reason why?不同：Is there any reason why you can’t come? (why 在定語從句中作狀語)

20. D。先行詞是人 The famous basketballer(著名的籃球明星)，用 who 引導(dǎo)定語從句。

21. D。先行詞是表時間的 age(時代)，并在定語從句中作狀語，用 when。

22. C。先行詞是地點名詞 places，并在定語從句中作狀語，用 where。

23. B。先行詞雖然是表地點的 York，但代表它的關(guān)系詞在定語從句中作及物動詞 visited 的賓語，排除 C 和 D；又因 that 不可引導(dǎo)非限制性定語從句，排除 A。

24. D。此題不僅考查定語從句，同時考查虛擬語氣。其中的without which為介詞加關(guān)系代詞結(jié)構(gòu)，介詞短語表達(dá)與過去事實相反的條件。
