Answer 1

B

試題分析：根據(jù)各個(gè)選擇項(xiàng)可知B不是賓語(yǔ)從句，它只是個(gè)簡(jiǎn)單句。A和D是that引導(dǎo)的賓語(yǔ)從句，其中that給省略了；C也是that引導(dǎo)的賓語(yǔ)從句。
點(diǎn)評(píng)：置于動(dòng)詞、介詞等詞性后面起賓語(yǔ)作用的從句叫賓語(yǔ)從句。賓語(yǔ)從句的語(yǔ)序必須是陳述語(yǔ)序。謂語(yǔ)動(dòng)詞、介詞、動(dòng)詞不定式，v.-ing形式后面都能帶賓語(yǔ)從句。有些形容詞（afraid,sure,glad等）之后也可以帶賓語(yǔ)從句。其基本特點(diǎn)是：賓語(yǔ)從句可以作及物動(dòng)詞、介詞及形容詞的賓語(yǔ)。
賓語(yǔ)從句的語(yǔ)序一律用陳述句語(yǔ)序。連接詞that引導(dǎo)賓語(yǔ)從句在句中無(wú)詞義，不充當(dāng)句子成份，多數(shù)情況下可以省略。whether 和 if 都可引導(dǎo)賓語(yǔ)從句，但 whether后可緊跟or not；whether從句可作介詞的賓語(yǔ)。
