Question

The inhalation (吸入) of asbestos particles is associated with a number of lung diseases, such as asbestosis and 1 cancer.
Asbestosis is caused by the entry of asbestos particles into the wall of the alveoli, causing scarring which limits the functioning of the lungs. The lung 2 its elasticity and may change shape. The initial symptoms of asbestosis are a tightness in the chest and breathlessness. In its 3 stages, sufferers develop the barrel-shaped chests associated with emphysema, cyanosis, (where the skin takes a bluish 4 ) and club fingers.
Lung cancer, the generic 5 for malignant tumors(肿瘤)of the alveoli and bronchial tubes, has been shown to be directly 6 to the inhalation of asbestos particles. As in the case of asbestosis, there is generally a period of inactiveness which may 7 from 25 to 30 years after initial exposure, despite the 8of further exposure. Research suggests that there is a direct correlation between the degree of exposure to asbestos 9the incidence of lung cancer. Where exposure occurs, the level of risk is further 10 by cigarette smoking. Asbestos workers who smoke cigarettes have a 90% greater risk of catching lung cancer than workers who do not 11.
Exposure to blue asbestos has been shown to producemesothelioma, a rare cancer of the outer lining of the lung or pleura. In a normal population the incidence of mesothelioma is extremely 12. Where epidemiological surveys have revealed a higher incidence of the disease, it is almost always related to 13 exposure.
14 changes in lung tissue caused by exposure to asbestos are pleural plaques and effusions. The former refer to a thickening of the lining of the chest wall, 15 the latter consists of a collection of fluid in the chest region outside the lungs. Pleural plaques commonly remain undiagnosed and generally have no detrimental effect on health.

文章讲述的是石棉肺癌的各种原因。
1.上下文，根据前一句a number of lung diseases可知，该处的疾病与lung有关系
2.上下文，根据前一句limits the functioning of the lungs可知，肺部功能受限，即减退，所以此处填减少了灵活性，弹性
3.上下文，根据上文The initial symptoms可知，此处是后来的发展阶段的
4.上下文，根据bluish可知，此处填的是颜色
5.lung cancer 肺癌，是一个专有名词，即term
6.be directly related to与……有直接的；联系
7.上下文，根据from 25 to 30可知，此处填的是extend延伸
8.上下文，根据despite可知，此处填的词与前面的after initial exposure是相反的，所以是……的缺少/缺失
9.固定搭配。Between ……and ……
10.上下文，根据后文a 90% greater risk of catching lung 可知，危险增加了
11.上下文，根据前一句Asbestos workers who smoke cigarettes have a 90% greater risk of catching lung cancer可知，
12.上下文，根据后一句Where epidemiological surveys have revealed a higher incidence of the disease，此处讲的肯定是少的病例。
13.上下文，上文一直在讲肺癌与asbestos石棉的关系
14.根据下文可知，此处讲的原因与前面的不一样，所以是其他的原因。
15.根据the former.....the latter可知，此处指对比，所以选whereas 然而。
