Answer 1

B

試題分析：根據各個選擇項可知B不是賓語從句，它只是個簡單句。A和D是that引導的賓語從句，其中that給省略了；C也是that引導的賓語從句。
點評：置于動詞、介詞等詞性后面起賓語作用的從句叫賓語從句。賓語從句的語序必須是陳述語序。謂語動詞、介詞、動詞不定式，v.-ing形式后面都能帶賓語從句。有些形容詞（afraid,sure,glad等）之后也可以帶賓語從句。其基本特點是：賓語從句可以作及物動詞、介詞及形容詞的賓語。
賓語從句的語序一律用陳述句語序。連接詞that引導賓語從句在句中無詞義，不充當句子成份，多數情況下可以省略。whether 和 if 都可引導賓語從句，但 whether后可緊跟or not；whether從句可作介詞的賓語。
