It still remains a question _____ life exists on any other planet in the solar system.

A．whyB．whether C．howD．where

B

解析試題分析：考查主語從句。本題中的it是形式主語，真正的主語從句是后面的whether life exists on any other planet in the solar system. 句意:在太陽系里的其它星球上是否存在著生命這件事情仍然是一個問題。根據(jù)句意說明本題的主語從句表示的是疑問的句意。ACD的語義和句意不符。故B正確。
考點：考查主語從句
點評：在句中作主語的名詞性從句稱為主語從句，主語從句所對應(yīng)的謂語動詞通常用第三人稱單數(shù)的形式。為了整個句子的平衡，主語從句經(jīng)常后置，并用it充當(dāng)形式主語(此時， that引導(dǎo)的主語從句若不放在句首，可以省略引導(dǎo)詞that)。解答這類題目，關(guān)鍵在于分析清楚句子結(jié)構(gòu)。通過判斷引導(dǎo)詞在從句中所作的成分及意義，來選擇正確的引導(dǎo)詞。
