資源簡介
1、主從復(fù)合句(名詞性、形容詞性、副詞性從句)及連接詞。例如:
1)Last week our maths teacher set so difficult an examination problem ______ none of us worked out.
A. that B. which C. as D. who
答案是C。本題考查定語從句的關(guān)系代詞,關(guān)系代詞在定語從句中作主語或賓語。work out是及物動詞,意為“計算出”,其后應(yīng)接賓語,這里as作關(guān)系代詞,和such或so連用。如果本句改為…worked it out,則該題應(yīng)選為A,構(gòu)成such…that結(jié)構(gòu),引導(dǎo)結(jié)果狀語從句。
