There are______ living things on the earth. We must value our home—the earth.
A. millions
B. million of
C. millions of

C

解析試題分析:句意:在地球上有數(shù)百萬的生物。我們必須珍惜我們的家園。Million百萬,修飾名詞時與具體數(shù)字連用,不用復(fù)數(shù),如ten million dollars;如果沒有具體數(shù)字時使用million的復(fù)數(shù)形式+of,如millions of reasons。根據(jù)題意,故選C。
考點:考查數(shù)詞的用法。
