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(guān)系代詞可以單獨(dú)用來引導(dǎo)非限制性定語從句。這時(shí)as所指代的不是主句中某個(gè)名詞，而往往指代整個(gè)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(guān)系代詞”結(jié)構(gòu)，常用來引導(dǎo)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 】

　　A. which

　　B. that

　　C. when

　　D. on which

　　【答案解析】：when是關(guān)系副詞，表示時(shí)間，在定語從句中作時(shí)間狀語。

　　4.The place _______ interested me most was the Children‘s Palace. 【 A 】

　　A. which

　　B. where

　　C. what

　　D. in which

　　【答案解析】：which用作關(guān)系代詞，在定語從句中作主語。

　　5._____ she was very tired， she went on working. 【 B 】

　　A. As

　　B. Although

　　C. Even

　　D. In spite of

　　【答案解析】：although：雖然，盡管。符合句意。

　　6.Read it aloud _______ the class can hear you. 【 A 】

　　A. so that

　　B. if

　　C. when

　　D. although

　　【答案解析】：so that：以至于�？梢砸龑�(dǎo)目的狀語從句，符合句意。

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

　　A. should we

　　B. we should

　　C. we shall

　　D. we ought

　　【答案解析】：by no means 帶否定意義，放在句首時(shí)句子部分倒裝。

　　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(yīng)該排除A和D，而B則表示進(jìn)行的虛擬結(jié)構(gòu)，因而正確的選項(xiàng)應(yīng)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(xiàng)as引導(dǎo)原因狀語從句與主句意義正好相反。B項(xiàng)為讓步狀語從句，把被強(qiáng)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(zhǔn)備好，我們明天就會(huì)很不好過。此題考查虛擬語氣，表示與現(xiàn)在事實(shí)相反，從句要用過去時(shí)。
