题目内容

【题目】We had better pay attention to some health problems that, when ________ in time, can become bigger ones later on.

A. not treated B. not to be treated

C. not having been treated D. not being treated

【答案】A

【解析】

考查分词做状语。句意:我们最好注意一些健康问题,当这些健康问题没有被及时解决的时候,后来就可能成为了大问题。定语从句的主语that,也就是some health problems与动词treat构成被动关系,所以使用过去分词形式,否定式是在前面直接加not。本句也可以理解为是省略句,在when的后面省略了they are。所以A项正确。

【题目】 Four and a half billion people worldwide live without a household toilet. Hundreds of millions of people are using facilities that are unhealthy and more than a billion people defecate (排泄) in the open.

Michael decided to take action in response to what is one of the world's greatest public health crises. He invited 32 health workers from 16 communities in the southern Highlands of Madagascar to attend a training to organize communities to completely wipe out open defecation.

After completing the initial training, the 32 health workers returned to their towns and got to work. They met with their community and began to map out their town. Together they toured the area and pointed out every spot where people often defecate. Many of them became embarrassed after realizing the high amount of human waste in their community. They then continued to make a bill for the total costs of trips to the local health center when being treated for gastrointestinal (肠胃的) diseases. They quickly began to realize the financial involvement, besides the health risks of open defecation.

The communities began to solve the problem on their own. They considered ways to reduce the cost, by using local materials. Bamboo fences were suggested as an alternative to wooden fences. Mud could be used to build walls instead of bricks. Before Michael starting his project, 267 toilets existed for the 6, 700 people living in the communities Michael aimed to reach. It was not enough at all. More than 300 additional toilets were built. He was pleasantly surprised by the enthusiasm he saw from the community towards making open defecation less.
