All the scientific evidence ________ that increasing use of chemicals in farming ________ damaging our health.                                         (2012·湖南，35)
A．show；areB．shows；are
C．show；isD．shows；is
D
D
解析　句意為：所有的科學(xué)證據(jù)表明：農(nóng)業(yè)方面越來越多化學(xué)物質(zhì)的使用正在損害著我們的健康。主語是evidence“證據(jù)(不可數(shù)名詞)”，所以謂語動詞應(yīng)用單數(shù)形式shows；賓語從句的主語是use“使用(不可數(shù)名詞)”，所以謂語動詞要用is。
