19．When H7N9bird flu first appeared，people didn't know ________ doctors could cure it．（　�。�
A．ifB．thatC．whatD．why

分析 當(dāng)H7N9禽流感首次出現(xiàn)時(shí)，人們不知道醫(yī)生能否治好這種病．

解答 答案：A．
根據(jù)people didn't know，可知本句考查了賓語從句的用法．在賓語從句中所使用的語序應(yīng)該是陳述句語序．再根據(jù) doctors could cure it，可知這里不缺少句子成分，所以不能用what或why引導(dǎo)，在這里含有疑問的語氣，所以用if引導(dǎo)這個(gè)賓語從句，表是否．故選A．

點(diǎn)評 此題考查賓語從句．考生在答題時(shí)要注意"賓語從句必須采用陳述語序"，根據(jù)上下文語境確定合適的選項(xiàng)．
