2019年上半年英語(yǔ)四級(jí)考試真題答案匯總 2019年6月英語(yǔ)六級(jí)答案題目（3）

原文：

Scientists have identified thousands of known ants species around the world. And only a few of them bug humans. Most ants live in the woods, or out in nature. There, they keep other creatures in check, distribute seeds, and clean dead and decaying materials from the ground. A very small percentage of ants do harm to humans. But those are incredibly challenging to control. They are small enough to easily slip inside your house. live in colonies that number in the tens of thousands to the hundreds of thousands, and reproduce quickly. That makes them good at getting in, and hard to kick out. Once they settle in, these insects start affecting your home. In addition to barging ants, other species can cause different kinds of damage. Some, like carpenter ants, can undermine a home structure, while others interfere with the electrical units.

Unfortunately, our homes are very attractive to ants, because it provides everything the colony needs to survive, such as food, water, and shelter. So, how can we prevent ants from getting into our homes? Most important of all, avoid giving ants any access to food, particularly sugary food, because ants have a sweet tooth. We also need to clean up spills as soon as they occur, and store food in air-tight containers. Even garbage attracts ants, so empty your trash as often as possible. And store your outside garbage in a lidded can, while away from doors and windows.

Questions 16—18 are based on the conversation you have just heard.

16. What does the passage say about ants?

17. What do we learn from the passage about carpenter ants?

18. What can we do to prevent ants from getting into our homes?

Passage 2

短文第2篇是一篇自述，介紹了“我”在老年保健領(lǐng)域的研究工作。體裁接近下午六級(jí)section C。文章主旨題，答案出現(xiàn)在聽(tīng)力開(kāi)篇處，第一句話直接出答案，在開(kāi)頭走神的考生很容易失去第一道題的答案。細(xì)節(jié)題。細(xì)節(jié)題，和第2 題的位置很接近。但通過(guò)反復(fù)聽(tīng)到的“old” 和”health”，不難找到答案。

原文：

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 affections. 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 infection. Felling unwell and being generally weak we want people to be healthy even when they are old.

Questions 19—21 are based on the passage you have just heard.

19. What is the focus of the speaker’s research?

20. What are the volunteers are asked to do in the research?

21. What does the speaker say will be the impact of his research?
