He never speaks to others until ______.
A．he speaksB．spoken toC．he is spokenD．he speaks to
B

試題分析：考查狀語從句的省略。本題在until后面省略he is；當(dāng)狀語從句的主語與主句的主語一致，且狀語從句中有系動詞be的時候，可以把狀語從句的主語和be動詞一起省略。句意：直到別人和他說話，他才會說。故B正確。
點(diǎn)評：當(dāng)狀語從句的主語與主句的主語一致，且狀語從句中有系動詞be的時候，可以把狀語從句的主語和be動詞一起省略。如果狀語從句中有it is的時候，it is 也可以省略。
