对待传染病的患病者，应关心他们，力所能及地帮助他们，而不是歧视他们。

Nowadays more and more people are concerned about their health. But how to keephealthy? Different people may give different answers to this question. In my opinion, it is essential to do the following. First, it is absolutely necessary to take some exercise every day. Research shows that getting plenty of exercise make the heart beat faster and the lungs work harder. This strengthens the heart, reduces the chance of heart attack, and helps lower blood pressure. That's why more and more people are becoming active in various kinds of sports and exercises. Every morning many people get up early and take much exercise. Some practice shadowboxing and swordplay while others run, jog, walk or dance to music. In the afternoon,there are also many people keen on sports. Some play basketball or volleyball or table tennis, others go in for gymnastics or track events. Through sports and exercise, people become healthier and stronger. Medical researchers have proved that what people eat affects their health. They advise people to eat more fruit and vegetables and less meat such as beef and pork because meat contains more fat than poultry and fish. Fat can build up in the arteries, block the flow of blood, and cause a heart attack or stroke. Getting rid of bad habits like smoking and drinking alcohol is also an important way to keep healthy. Smoking and drinking alcohol injure one's health a great deal, and therefore should be given up. Unfortunately few people follow this advice. If people follow these three ways of keeping fit, they greatly improve their health.

解题思路：传统的健康观是“无病即健康”，现代人的健康观是整体健康，世界卫生组织认为，健康是指一种身体上、心理上和社会适应方面的良好状态，而不仅仅是没有疾病和不虚弱．近年来，世界卫生组织又把道德修养和生殖质量也纳入了健康的范畴．

勤洗手，勤换衣，不随地吐痰等卫生习惯，切断了病原体离开传染源到达健康人所经过的途径，属于预防措施中的切断传播途径。

传染病要想流行起来，必须具备三个环节：传染源、传播途径和易感人群．这三个环节必须同时具备，缺一不可．据此可知，控制传染病的措施有三个：控制传染源、切断传播途径、保护易感人群．
A、注射疫苗应属于预防传染病的保护易感人群，故不符合题意．
B、勤洗手应属于预防传染病的切断传播途径，故不符合题意．
C、与乙肝患者的日用品分开使用应属于预防传染病的切断传播途径，故不符合题意．
D、乙肝属于血液传染病，其传播途径有四个：母婴传播、血液传播、性接触．其它途径并不会传染乙肝．所以，与乙肝患者彻底断绝来往没有必要．故符合题意．

Last months several places in Beijing were blanketed with thick yellow fog .Everything around disappeared from oursight .Some highways were closed.Traffic jams were commonly seen in the street.Many people,especially children and seniors,even found it difficult to breath.As a result,local hospitals were crowd with people who had problems with noses and lungs.Part of the cause was the dry weather,but the severely damaged environment contributed a lot to this nightmare.Personally I don't get many health problems in the haze because I stayed mostly indoors.But to make a significant chance we really have to do more protect our environment.To live a better life we have to push on with the economy,but it would be meaningless if we have to achieve it at the cost of our breathing ai

解题思路：此题考查传染病的预防措施：控制传染源、切断传播途径、保护易感人群，据此答题．

传染病能够在人群中流行，必须具备传染源、传播途径、易感人群这三个环节，缺少其中任何一个环节，传染病就流行不起来，传染源是指能够散播病原体的人或动物；传播途径是指病原体离开传染源到达健康人所经过的途径；易感人群是指对某种病原体缺乏免疫力而容易感染该病的人群，预防传染病的一般措施有控制传染源、切断传播途径、保护易感人群，病原体是指引起传染病的细菌、病毒和寄生虫等生物，专家号召大家搞好个人饮食卫生，勤洗手属于切断传播途径．
