［解析］ 第一個(gè)下劃線處應(yīng)填入一個(gè)可以引導(dǎo)of的賓語(yǔ)從句泛指“你現(xiàn)在所擁有的東西”且在該賓語(yǔ)從句內(nèi)部充當(dāng)have的賓語(yǔ)的詞， 這樣的引導(dǎo)詞只能是what， 由此可以直接排除選項(xiàng)A、 C、 D而選出B。

A. why B. what C. who D. that
［答案］ A
［解析］ 下劃線處引導(dǎo)的名詞性從句屬于介詞on的賓語(yǔ)， 在該名詞性從句中引導(dǎo)詞充當(dāng)原因狀語(yǔ)， 所以應(yīng)選A。

10. Information has been put forward ____ more middle school graduates will be admitted into universities. (上海2000)
A. while B. that C. when D. as
［答案］ B
［解析］ 陳述客觀情況的名詞性從句的引導(dǎo)詞之后是完整的陳述句， 引導(dǎo)詞本身不充當(dāng)該名詞性從句中具體的句子成分， 有這樣用法的引導(dǎo)詞只能是that。本題下劃線處引導(dǎo)了information的同位語(yǔ)從句(為避免頭重腳輕， 本句中information的同位語(yǔ)從句與information之間被謂語(yǔ)動(dòng)詞部分隔開(kāi))。

A. No matter what B. No matter which C. Whatever D. Whichever
［答案］ D
［解析］ 下劃線處引導(dǎo)全句的主語(yǔ)， 因此不能選用只能引導(dǎo)讓步狀語(yǔ)從句的選項(xiàng)A、 B； 下劃線處表示“任何一支(獲勝的球隊(duì))”之意， 用which的相關(guān)形式更為合適， 因此進(jìn)一步排除C而選出D。
