　　典型例題

　　1)Alice received an invitation from her boss, ___came as a surprise.

　　A. it B. that C. which D. he

　　答案C. 此為非限定性從句，不能用 that修飾，而用which.，it 和he 都使后句成為句子，兩個獨立的.句子不能單以逗號連接。況且選he句意不通。

　　2)The weather turned out to be very good, ___ was more than we could expect.

　　A. what B. which C. that D. it

　　答案B。which可代替句子，用于非限定性定語從句，而what不可。That 不能用于非限定性定語從句，it不為連詞，使由逗號連接的兩個句子并在一起在英語語法上行不通。

　　3)It rained hard yesterday, ____ prevented me from going to the park..

　　A. that B. which C. as D. it

　　答案B.
