1.He is good at English， _______ we all know. 【 B 】
A. that
B. as
C. whom
D. what
【答案解析】：as作關系代詞可以單獨用來引導非限制性定語從句。這時as所指代的不是主句中某個名詞，而往往指代整個主句的含義。as在從句中可以作主語、賓語。從句可放在主句后，也可置于主句前。在本句中，as作賓語。
2.The pen _______ he is writing is mine. 【 A 】
A. with which
B. in which
C. on which
D. by which
【答案解析】：with which是“介詞+關系代詞”結(jié)構(gòu)，常用來引導定語從句。with有“用”的意思，介詞之后只能用which，不能用that. with which在定語從句中作狀語，即he is writing with a pen.
3.Do you know the year _______ the Chinese Communist Party was founded? 【 C 】

4.The place _______ interested me most was the Children‘s Palace. 【 A 】
A. which
B. where
C. what

7.By no means _______ look down upon the disabled. 【 A 】

8._______ today， he would get there by Friday. 【 C 】
A. Would he leave
B. Were he leaving
C. Were he to leave
D. Had he left
【答案解析】：這是省略連詞if 的表示將來虛擬的倒裝結(jié)構(gòu)。根據(jù)所講過的表示將來的虛擬句的結(jié)構(gòu)：should + do或 were to do ，故首先應該排除A和D，而B則表示進行的虛擬結(jié)構(gòu)，因而正確的選項應該是C.
9._______， it is quite easy to drill a hole in it with a eraser. 【 B 】
A. Hard a diamond is
B. Hard as a diamond is
C. As a diamond is hard
D. How hard is a diamond
【答案解析】：A缺少連詞，C項as引導原因狀語從句與主句意義正好相反。B項為讓步狀語從句，把被強調(diào)部分放在句首，此處as可用though來代替。
10.If we _______ everything ready by now， we should be having a terrible time tomorrow. 【 A 】
A. hadn‘t got
B. didn’t get
C. wouldn‘t have got
D. wouldn’t get
【答案解析】：譯文：如果到現(xiàn)在一切都沒準備好，我們明天就會很不好過。此題考查虛擬語氣，表示與現(xiàn)在事實相反，從句要用過去時。
