• B． why is he leaving
• C． whether he is leaving
• D． whether is he leaving

Answer 1

分析 --我不知道他為什么要離開(kāi)．--因?yàn)樗�要照顧他的母親．

解答 答案：A 根據(jù)Because he has to look after his mother．推測(cè)可知：上文應(yīng)該是問(wèn)原因，故引導(dǎo)詞應(yīng)該是why，所以排除選項(xiàng)C和D；賓語(yǔ)從句應(yīng)該用陳述語(yǔ)序，即主語(yǔ)+謂語(yǔ)，所以排除B．故選：A．

點(diǎn)評(píng) 主要考查賓語(yǔ)從句，一定注意賓語(yǔ)從句的引導(dǎo)詞，以及賓語(yǔ)從句的時(shí)態(tài)和語(yǔ)序問(wèn)題．把握好這幾點(diǎn)，是做好此類(lèi)題目的關(guān)鍵！就本題而言主要考查賓語(yǔ)從句的引導(dǎo)詞和語(yǔ)序．
