A number of persons have expressed concern about possible health dangers to workers who use devices called video-display terminals (终端) or VDTs.
These are the devices used to show computer information. Some reports link VDTs to health disorders including eye problems and muscle problems. Even the health of the pregnant women and their unborn babies is said to be endangered. Video-display terminals produce low levels of the electromagnetic radiation(电磁辐射). Experts say most modern VDTs have been designed to limit the dangers from such radiation. However, study shows that even low levels of electromagnetic radiations can affect the growth of the cells. As a result, some doctors advise women to stop working with VDTs while they are pregnant.
One study found women who work with VDTs in early pregnancy are more likely than others to have their pregnancy end unexpectedly.
Researchers said that this does not necessarily mean that VDTs themselves cause problems. Some experts said the findings show working conditions, not the machines, cause the problems. Law makers in m6re than American states have proposed bills to control working conditions for VDT operators.
What is the best title of the passage?
选项
A、Problems Existing in the American States.
B、Working Conditions for VDTs Operators.
C、Health Dangers to Workers Using VDTs.
D、How to Protect the Pregnant Women.
答案
C
解析
本题为主旨归纳题。文章一开始就指出 VDTs 对健康的危害,并通过专家的研究成果证实这一观点,最后还指出造成危害的真正原因。整篇文章都是围绕“危害”这一话题展开的。
