According to a UN report, one third of the world population have no to clean drinking water and health care.

A. means

B. approaches

C. ways

D. access

答案：

A. means

B. approaches

C. ways

(答案→)D. access

解析：句意：根据联合国的报告，三分之一的世界人口喝不到清洁的饮用水和卫生保健。access意思是“(使用或见到的)机会，权利”，后面与介词to连用。have access to sth.有接近……的机会。 由句意可知选D。

考点: 考查名词词义辨析的用法。
