every與each的區(qū)別every用來表整體，each用來表個別，each最低需是兩，every最低需是三。every作主用單數(shù)，each可單也可復(fù)，作主、定用單數(shù)，其他情況用復(fù)數(shù)。

3．Bookswillonlybeoncomputers，notonpaper.

書只會在電腦上，而不會在紙上。

papern.“紙，紙張”，是不可數(shù)名詞。表示“一張紙”用apieceofpaper，“兩張紙”用twopiecesofpaper。

D．pollute；polluted

點撥：瀏覽題干可知，第一空在句中作主語，故用名詞pollution；第二空在系動詞are后，故用形容詞polluted；pollute是動詞。句意為“現(xiàn)在污染很嚴重。一些河流、湖泊被污染了”。
