英语四级听力真题复习短文2

My research focus is on what happens to our immune system as we age. So the job of the immune system is to fight infections. It also protects us from viruses and from autoimmune diseases. We know that as we get older, it's easier for us to get infections. So older adults have more chances of falling ill. This is evidence that our immune system really doesn't function so well when we age. In most of our work, when we were looking at older adults who've got an illness, we always have to have health controls. So we work very closely with a great group of volunteers called the One Thousand Elders, these volunteers are all 65 or over but in good health. They come to the university to provide us with blood samples to be interviewed and to help us to carry out a whole range of research. The real impact of our research is going to be on health in old age. At the moment, we are living much longer. Life expectancy is increasing at 2 years for every decade, that means an extra 5 hours a day. I want to make sure that older adults are still able to enjoy their old age, and that they are not spending time in hospital with infections, feeling unwell and being generally weak. We want people to be healthy even when they are old.

我的研究重点是我们的免疫系统在随着年龄的增长会发生什么变化。免疫系统负责对抗感染。它还能保护我们免受病毒和自身免疫性疾病的侵害。我们知道,随着年龄的增长,我们更容易感染。所以老年人有更容易生病。这证明当我们变老时,我们的免疫系统确实不能很好地发挥作用。在我们的大部分工作中,当我们看到患有疾病的老年人时,我们总是必须对他们进行健康管理。因此,我们与一大群人组成的志愿者团体紧密合作,这个团体叫“千个老人”,这些志愿者都是65岁或65岁以上,但健康状况良好。他们来这所大学是为了给我们提供接受预检的血样并帮助我们进行一系列的研究。我们研究的真正影响在于关注老年人的健康。目前,我们的寿命要比过去长得多。预期寿命是每10年就增加2年,这意味着每天增加5个小时。我想确保老年人仍然能够享受他们的老年生活,并且他们不会因为感染、身体不适和普遍虚弱而在医院呆上一段时间。我们希望人们即使在年老的时候也保持健康。
