       在法庭上,我们跟父亲见了面。父亲仍旧穿着他那件灰布旧棉袍,可是没戴眼镜。我看到了他那乱蓬蓬的长头发下面的平静而慈祥的脸。   

      “爹!”我忍不住喊出声来。母亲哭了,妹妹也跟着哭起来。  

      “不许乱喊!”法官拿起惊堂木重重在桌子上拍了一下。

     In 2004, the World Health Organization, WHO, warned of a possible outbreak of another serious disease

which may be even more deadly than SARS. The WHO believes that it is likely that bird flu will spread to

human beings in the next few years. If it does, up to seven millions people could die from the disease.

     Diseases like bird flu are caused by viruses, that is, tiny things which change and become more dangerous

over time. When a new type of a common virus changes, it may be able to get past the body's immune (免疫

的) system. If that happens, humans are in great danger until a cure or treatment becomes available.

     There have always been viruses and people always get sick, of course, but as we saw with SARS, the

situation is more difficult today. People travel more than ever before, which means that disease can spread

quickly and across large areas-in fact the whole world.

     Scientists are already working on drugs that will prevent or limit the effect of a new virus, but the process

takes time. It is just as important to make sure that countries, especially poor countries, are prepared to deal

with the disease. New disease usually affect poor areas the most, so we must help develop health care in all

countries.
