3、 ， 并在 答 题 卡 上 将 该 项 涂 黑 。AResearchers at Oxford University say they have developed a new method that could predict heart attacks years before they happen. They use mathematical algorithms(演算法) to examine CT images of a patients heart. One report on their study has been published in the medical journ

4、al The Lancet.Most heart attacks result from a build-up of fatty tissue inside arteries(动脉) that carry blood from the heart to other areas of the body. Too much buildup can block this flow of blood and cause a heart attack. Currently, doctors use CT scans to learn when a sticky substance called plaq

5、ue has already built up inside an artery. The new technology is designed to predict which arteries are at risk for future buildup. How much fat is present around heart arteries also can be measured. That fat changes when an artery becomes inflamed(发炎), serving as an early warning system for heart at

6、tacks.Charalambos Antoniades, a professor of cardiovascula(心血管) medicine at Oxford University, believes the research shows this method could be very effective in getting patients to take early steps to prevent future problems.“Say your arteries are inflamed and a narrowing will be developed five yea

7、rs down the line. So maybe you can start preventive measures to avoid this formation of plaques,” he said. “If you are able to identify inflammation in the arteries of the heart, then you can say which arteries will cause heart attacks.”Antoniades added that researchers had yet to estimate exactly h

8、ow many heart attacks could be prevented. But he said he believes the technique could help identify between 20 to 30 percent of people at risk of having one.He added that the new technology will make such predictions easier because it works together with existing CT technology.21. You can identify w

Favorable.BMore than nine out of 10 young people expose themselves to the blue light from smartphones before bed, causing problems with sleep. A new survey also shows more than 28 million people

11、in the UK regularly get no more than seven hours sleep a night. Prof Richard Wiseman, who commissioned the YouGov poll described the findings as “extremely worrying”. Of the 2,149 adults questioned, 78% said they used electronic devices before going to bed. This rose to 91% among the 18 to 24-year-o

12、lds questioned in the survey.Getting less than seven hours sleep a night is below the recommended guidelines, and is associated with a range of problems, including an increased risk of weight gain, heart attacks, diabetes and cancer. “The blue light from these devices suppresses(压制) the production o

Teenagers are rec

14、ommended to get more, about nine hours. The proportion(比例) of people thought to be getting too little sleep had risen by a fifth since a “bedroom poll” conducted last year by the National Sleep Foundation.Last week revealed opticians were warning that overuse of smartphones may be increasing peoples

15、 risk of eye damage. Optician Andy Hepworth said: “Blue violet light is potentially harmful to the back of your eyes.” So over a long period of time it can damage your eyes.

20、h whats known as a Received Pronunciation (RP,标准发音) accent, also called “the Queens English”. However, while many people do talk this way, most Britons speak in their own regional accents.Scouse, Glaswegian and Black Country from Liverpool, Glasgow and the West Midlands are just three of the countle

21、ss non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking in a RP accent may mean a British person is judged and even treated differently in their everyday life.In a 2

22、015 study by The University of South Wales, videos of people reading a passage in three different UK accents were shown to a second group of people. The group then rated how intelligent they thought the readers sounded. The lowest-rated accent was Brummie, native to people from Birmingham, a city wh

23、ose accent is considered working class.However, there is no need to be disappointed though you are not speaking in an RP accent. In fact, doing the opposite may even give you strength.Kong Seong-jae, 25, is an internet celebrity from Seoul. After studying in the UK, he picked up several regional acc

24、ents. Hes now famous for his online videos, where he shows off the various accents hes learned. “British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I think it makes a bit of bond between local people and foreigners to speak in the

25、ir local accent,” he said.So if youre working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham.

29、een any?” That is the Fermi Paradox(悖论) named after Enrico Fermi, a physicist who posed it in 1950.Fermis argument ran as follows. The laws of nature supported the appearance of intelligent life on Earth. Those laws are the same throughout the universe. The universe contains zillions of stars and pl

30、anets. So, even if life is unlikely to arise on any particular astronomical body, the sheer abundance of creation suggests the night sky should be full of alien civilizations. Fermi wondered why aliens had never visited the earth. Today, the paradox is more usually cast in light of the inability of

31、radio-telescope searches to detect the equivalent(相等的) of the radio waves that leak from Earth into the universe, and have done for the past century.Thinking up answers to this apparent contradiction has become something of a scientific parlour(客厅) game. Perhaps life is really very unlikely. Perhaps

32、 the priests are right: human beings were put on Earth by some creator God for His own unknown purposes, and the rest of the universe is merely background scenery. Perhaps there are plenty of aliens, but they have decided that discretion is a safer bet than gathering together. Or perhaps galactic(银河

33、的) society avoids communicating with Earth specifically. One frightening idea is that technological civilizations destroy themselves before they can make their presence known. They might blow themselves up after inventing nuclear weapons (an invention that, on Earth, Fermi had been part of), or cook

34、 themselves to death by over-burning fossil fuels.In a paper published last month on arXiv, an online repository(文献库), a group of three astronomers at Pennsylvania State University have analyzed the history of alien hunting and come to a different conclusion. In effect, they reject one of the parado

35、x s main theory. Astronomers have seen no sign of aliens, argue Jason Wright and his colleagues, because they have not been looking hard enough.32. What is the Fermi Paradox?A. The law of universe supported the appearance of aliens but we never see any.B. A theory about whether aliens exist on the e

36、arth and why we cant see them.C. Fermi thought that aliens never existed because it was completely a paradox.D. Fermi concluded that aliens did exist but they could not be seen by humans.33. What can we conclude from the second paragraph?A. The universe doesnt provide the abundance of creation of li

37、fe.B. Fermi thought aliens never visited the earth in the history of human.C. The inability of radio-telescope may result in the failure of finding aliens.D. The civilizations on the earth have been detected by aliens in the universe.34. What does the word underlined in the third paragraph mean?A. G

38、etting together.B. Fighting each other.C. Hating each other.D. Living separately.35. How do Jason Wright and his colleagues find the Fermi Paradox?A. They firmly believe that it is out of date.B. They actually doubt the base of the paradox.C. They want to prove that it is completely right.D. They co

The circadian rhythm is like a clock or timer.C. Specifically, their investigation found the following information:D. The new studys findings could
