1、 Wednesday微型机器人在医学中的应用
In the near future, the doctors who treat our illness might be tiny machines that swim through our bodies. Some movies have played with the idea of making machines the size of a cell. Today robot technology has brought the idea closer to the real life. In my laboratory, I'm just trying to build such intelligent, or smart, tiny robots.
Tiny living things, such as bacteria, have many intelligent actions. If we can make robots copy some of them, it's very exciting. The way bacteria travel across their environment is unbelievable. At first, they move around without purpose, but when they start sensing food, like an amino acid(氨基酸), they will move gradually in that direction. As an expert making robots, I think it is great to make tiny robots that can do the same thing.
For example, look at something like E. coli(大肠杆菌). It can sense amino acids around it. It can change how it's moving. It can rebuild or repair itself. In fact, E. coli does all these so well that some researchers are using it as part of their tiny machines. They are making their tiny robots get free rides from E. coli. And E. coli does all the sensing for tiny robots and directs their movements.
We' re already using smaller and smaller medical tools, like catheters(导管) that can travel deep into your brain to treat a blood clot. Next, we will put tiny robots into the body that can travel into even smaller spaces and treat illness at an early time. Imagine a tiny robot that can treat a blood clot deep in your brain that can't be reached with the catheters we are using today.
We may not actually need something as powerful as artificial intelligence (AI) in these cases. We can still build a very useful tiny robot with a low degree of intelligence. For example, if a tiny robot notices a blood clot, it can slowly move in that direction, and carry medicine directly to that part. It might only have the intelligence of bacteria but could still work.

7、 Tuesday基塔瓦岛的健康饮食
Staffan Lindeberg is a medical teacher at the University of Lund in Sweden. He was文章音频interested in a Stone Age diet. In the early1990s, he began to study the diet of the people on the island of Kitava as it was very close to the Stone Age diet. While there, he found that people did not suffer from heart attacks, diabetes, being overweight and many other diseases common in Western countries.
As a result of his findings, he decided to test patients in Sweden to see how such a diet would affect them. Fourteen patients followed a Stone Age diet while another fifteen followed a Mediterranean diet, also healthy with lots of fruit and vegetables. All of the patients in the test had high levels of blood sugar, most suffered from diabetes and all had heart problems.
At the end of three months, the group following the Mediterranean diet had reduced their levels of blood sugar by a small amount but those following the Stone Age diet had much lower levels of sugar in their blood. The patients in both groups also lost weight although the level of sugar in the blood and the patients' weight didn't seem to be related.
So, what is it about the Stone Age diet that can make us healthier? The diet contains some meat, fish, vegetables and nuts but it doesn't contain any milk products or wheat, and there is no salt.
The next question is whether the people of Kitava are healthier than us. After all, their life expectancy is much lower. According to Staffan Lindeberg, this is not as simple as we may think. Because of their poor healthcare, there is more chance of them dying at a young age. However, if people on the island of Kitava manage to reach fifty, they are likely to live as long as people in more developed countries.
(1)、What does the underlined word "them" refer to in Paragraph 2?A、Staffan Lindeberg's findings. B、Patients in Sweden. C、 D、People on the island of Kitava.(2)、What did the test show?A、The Stone Age diet could reduce levels of blood sugar. B、The Mediterranean diet could help treat diabetes. C、The Mediterranean diet could help people lose weight quickly. D、High levels of blood sugar could cause people to lose weight.(3)、Which of the following pictures shows the Stone Age diet?A、B、
C、
D、
(4)、The people of Kitava have lower life expectancy because of ____ .A、unhealthy eating habits B、poor living environment C、poor medical condition D、a serious disease at a young age -

After he handed in his drawing, a staff person of the activity learned more about him. His story made the leader of the company join the fight against cancer.
Porter will continue helping people in need. "I hope doctors can find better treatments for cancer."

15、 阅读下面短文,然后判断短文后面的句子正误。
In the world full of games, apps and funny videos, people spend less and less time on things. Research has shown that on average, people spend less than one minute on one work of art. The Internet has millions of websites, so you might expect people to slow down when they're in museums full of great works of art. But you are wrong.
In recent years, museums have been working to change the situation. Over 170 museums around the world celebrate Slow Art Day. They ask their visitors to spend at least 5 to 10minutes looking at just one work of art.
Slow Art supporters believe that when visitors spend more time looking at a work of art, they enjoy it more. By spending time, they are able to notice more things about the work of art. Studying a work of art for more time can also help people get a better understanding of the artist's ideas and what the artist went through to create the work. Most museums taking part in Slow Art Day choose just a few works for their visitors. In their opinion, when people visit a museum with lots of works of art, they feel like they must see everything in the museum. As one expert said, "You can't really see a painting as you're walking by it."
(1)、Because of games, apps and funny videos, people spend less and less time on things.(2)、To celebrate Slow Art Day, museums suggest visitors spend 5~10 minutes on all the works of art.(3)、Spending more time on the work of art can help visitors understand the artists' ideas better.(4)、Museums taking part in Slow Art Day choose lots of works for their visitors. -
