A.show;are B.shows;are
C.show;is D.shows;is
答案 D
解析 句意为:所有的科学证据表明:在农业中越来越多地使用化学物质正在损害着我们的健康。主语evidence意为"证据",是不可数名词,所以谓语动词应用单数形式shows;increasing use of chemicals in farming是动名词短语作主语,谓语动词要用单数形式is。所以选D。

A.a river lies that

解析 句意为:我们家前面有一条河,过去我们常常在那儿游泳。In front of our house是介词短语,介词短语放在句首时,句子要完全倒装,排除A、B两项;后面是定语从句,a river是先行词,定语从句we used to swim中缺少地点状语,要用where引导。所以选D。
