Scientists think that there has been life on Earth for _______ years.       
A. millions     
 B. millions of
C. million of
D. million
B

試題分析：此題重點(diǎn)考查數(shù)詞的表達(dá)法，如果有確切的數(shù)字 thousand 或million后面直接跟名詞，thousand 和million等不用復(fù)數(shù)，也不用of，而thousands of，millions of直接跟名詞或代詞,前面不用確切的數(shù)字表示約數(shù)，根據(jù)題意故選B
點(diǎn)評(píng)：正確區(qū)分是確切數(shù)還是不確切數(shù)，二者不能混淆，關(guān)鍵是thousand和million加不加s。
