試題分析：句意：大陸的人去香港買嬰兒食品的原因是人們不確信在大陸生產(chǎn)的嬰兒食品的安全性。第一空是why引導(dǎo)的定語從句，先行詞reason，關(guān)系詞在從句中作狀語；第二空是是固定短語be convinced of確信。根據(jù)句意故選C。
點(diǎn)評：本題難度適中。定語從句的考查關(guān)鍵在于定語從句的成分分析，如果缺少主語，賓語，表語，定語就使用關(guān)系代詞，否則，就使用關(guān)系副詞。這里把定語從句與固定短語放在一起考查增加了試題的難度。
即學(xué)即練：The Chinese government has made the Mid-Autumn Festival a legal holiday, ______ people will have a day off.
A. when           B. which          C. where        D. what
解析：A。句意：考查非限制性定語從句。the Mid?Autumn Festival為先行詞，指時間在從句中作時間狀語，因此引導(dǎo)詞用when。
