1. They ______ on the program for almost one week before I joined them, and now we _____on it as no good results have come out so far.
A. had been working; are still working B. had worked; were still working
C. have been working; have worked D. have worked; are still working
此题的时间参照点是before I joined them,，所以第一个空应该用过去完成进行时，第二个空根据时间now用现在进行时。
2. It would be a good idea to use a plastic bottle, ___cut off, as a container to grow young plants in.
A. of which the top B. the top is C. the top of which D. with its top
此题是独立主格结构，如果题干改为 ____is cut off,答案则为A或C
3. ______ is it _____ has made Peter _____ he is today?
A. What; that; that B. That; that; what C. What; what; that D. What; that; what
用还原法则为 It is what that has made Peter what he is today k可知是强调句式。
4. Before he went abroad，he spent as much time as he _____ English.
A. could learning B. learned C. to learn D. could learn
spend time (in) doing sth. 如果改为he did what he ______, 则答案为could to learn.
5. The person we talked about ____ our school last week．
A．visiting B．will visit C．visited D．has visited
此题中包含一个定语从句，the person既作先行词，又作句子的主语，要填入的应该是句子的谓语，根据后面的时间状语为last week，应选过去时。句中包含的定语从句we talked about中about虽为介词，但不影响主句的谓语，故应选C。
观察下面三个句子：
□The person we spoke to ____ no answer at first．
A．making B．makes C．make D．made
此题中也包含一个定语从句we spoke to，the person既作先行词，又作句子的主语，要填入的应该是句子的谓语，根据句子的需要，应选过去时。本题中的to为陷阱，实际上它属于定语从句中，而不影响主句的谓语动词。故D正确。
□The person we referred to（提及）____ us a report tomorrow．
A．giving B．will give C．gave D．give
同上题一样，句中包含定语从句we referred to，所缺成份为句子的谓语，又根据句中的tomorrow，故用将来时。选B。
□The days we have been looking forward to ____ soon．
A．coming B．will come C．came D．have come
同理，此句中的定语从句包含短语look forward to，虽然to 为介词，但并不影响主句的谓语动词，只是一个陷阱而矣。又根据句中的soon，应用将来时，故选B。
6. Not far from the club there was a garden, ____ owner seated in it playing bridge with his children every afternoon. A. whose B. its C. which D. that
答案为B。此题关键是理解seated这个单词，它是过去分词，而不是作谓语的过去式。它不能在句中谓语。所以后面句子不是一个非限制性定语从句，而是一个独立主格结构，故选代词its。
7. You should treat him (in) the way ____ suits him most.
A. that B. in which C. / D. why
此题中先行词the way 后面的定语从句中充当主语。故只能选A。如果先行词the way有从句中充当状语，则可以用that, in which或省略。
8. He is a strict but kind-hearted father, ____ the children respect but are afraid of.
A. / B. that C. for whom D. one whom
此题答案只能为D。替代词one在句中作同位语，代指father，后面再接一个定语从句。先行词one 又在从句中充当宾语。
9. --- You haven’t been to
A. Yes, I have B. Yes, I haven’t C. No, I have D. No, I haven’t
注意题中最后一个单词again（看三遍！）。不要误选为D。答案应为A。全句的句意为“你没有去过北京，是不是？”“不，我去过。我多么想再一次去那里。”
10. Not only ______the jewelry she ____been sold for her son’s gambling debts but also her house.
A. is； has B. has； had C. has； has D. 不填； has
此题中由于Not only 置于句首，故用部分倒装结构。第一个has助动词，是句中谓语动词has been sold中has的提前。第二个has为实义动词，属于定语从句中，表示“有”的意思。本句的意思为：不但是她所有的珠宝而且还有她的房子一起已经被卖掉作为她儿子的赌债了。答案为C。
