Question

There are some health problems that, when ___in time, can become bagger ones later on.

A．not treated	B．not being treated
C．not to be treated	D．not having been treated

Answer 1

A

试题分析：考查非谓语动词的用法。句义：有一些健康问题，如果不及时治疗的话，后来很可能会成为乞丐把你的钱花光。关键词health problems“健康问题”和“治疗”之间的关系是被动关系，与done的进行式，将来式，完成式没关系，所以Ｂ C  D不对，A正确。
