In the late 1800抯 Ellen Richards , began work in the new field of “sanitary scie

In the late 1800抯 Ellen Richards , began work in the new field of “sanitary science”which was concerned with waste removal, water purification and _______ .

[]

A．　to ventilate adequately　B． adequate ventilation　

C．　adequate ventilateD． ventilation adequately

试题答案

答案：B

提示：

此处生词量较大，但是仍然可以看出： adequate ventilation是定语+名词的词组，与waste removal, water purification在“词语一致性”和“词类相同性”两个方面都很相近，故而应该选B． adequate ventilation。
