Question

_____ John won a gold medal in the English competition really excited his family.

A．That

B．when

C．which

D．what

Answer 1

A

試題分析：考查主語從句。本題中的that引導(dǎo)主語從句that John won a gold medal in the English competition.在句中that不充當任何成分，只起引導(dǎo)和連接作用。句意：John在英語比賽中贏得了金牌這件事情讓他的家人很高興。BC兩項都有疑問的意思，what要在句中充當一定的句子成分。故A正確。
點評：在復(fù)合句中做主語的從句叫做主語從句，它的位置與陳述句基本結(jié)構(gòu)中的主語相同。引導(dǎo)主語從句的關(guān)聯(lián)詞有：連詞：that, whether；連接代詞：who, whom, whose, what, which；連接副詞：when, where, why, how；復(fù)合詞：whatever, whoever, whomever, when?螄ever, wherever, whichever, however.解答這類題目，關(guān)鍵在于分析清楚句子結(jié)構(gòu)。通過判斷引導(dǎo)詞在從句中所作的成分及意義，來選擇正確的引導(dǎo)詞。
