26、 People do better when more is expected of them. In education circles, this is called the Pygmalion Effect.
The Pygmalion effect got its name from the story of Pygmalion, a mythica(虚构的)Greek sculptor. Pygmalion carved a statue of a woman and then fell in love with it. He appealed to Aphrodite, the goddess of love, who brought the statue to life and helped the couple get married. Just as Pygmalion’s fixation on the statue brought it to life, our focus on a student can do the same in schools. Research by Robert Rosenthal and Lenore Jacobson examined the influence of teachers’ expectations on students’ performance. They began by testing the IQ of elementary school students. Teachers were told that the IQ test showed around one-fifth of their students to be unusually intelligent. But unknown to the teachers, the “gifted” students were chosen at random. Actually they had no big statistical advantage over the other kids. As the study period ended, all students had their IQs retested. Both groups showed an improvement. Yet those who were described as intelligent experienced much greater gains in their IQ points. Rosenthal and Jacobson owed this result to the Pygmalion effect. Teachers paid more attention to “gifted” students, offering more support and encouragement than they would otherwise.
In general, teachers have the power to influence how the students behave by holding high expectations. If a teacher thinks a student is brilliant, they will treat them as such. The student then gets more opportunities to develop their ability, and their performance improves. This works both ways. When a student expects a teacher to be excellent or successful, they tend to be attentive and supportive. In the process, they improve their performance, too. Students who act interested in lectures create interesting lecturers.
【1】Where did the Pygmalion effect get its name from?
A.A statue of a lady. B.The goddess of love.
C.A character in a literary work. D.The story made up by Pygmalion.
【2】The underlined expression “fixation on” in Paragraph 2 most probably means
A.worship of B.affection for C.marriage to D.sympathy for
【3】What is the purpose of Rosenthal and Jacobson’s research?
A.To improve the kids’ IQ. B.To pick out gifted students.
C.To expand teachers’ influence. D.To examine the Pygmalion effect.
【4】What can students do to make a teacher excellent?
A.Support the teacher by treating them as excellent.
B.Attend interesting lectures given by the teacher.

27、The spread of Western eating habits around the world is bad for human health and for the environment. Those findings come from a new report in the journal Nature.
David Tilman is a professor at the University of Minnesota. In the study, he examined information from 100 nations to show what people ate and how diet affected health. Mr. Tilman noted a movement beginning in the 1960s. He found that as nations industrialized(工业化), population increased and earnings rose. More people began to adopt what has been called the Western diet. The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker.
“The food, let us say, in the 15 richest nations of the world, right now contains about 400 or 500 extra calories(热量) a day that are eaten beyond what people need, and that leads people to gain weight.”
David Tillman says overweight people are at greater risk for diseases like diabetes, heart disease and some cancers. Diabetes is shooting to very high rates in the United States and across Europe. Heart disease is a major cause of death in the Western nations. Unfortunately when people become industrialized, if they adopt this Western diet, they are going to have these same health problems.
A diet bad for human beings, it seems, is also bad for the environment. As the world’s population grows, experts say more forests and areas will become farmland for crops or grasslands for raising cattle. These areas will be needed to meet the increasing demand for food.
Mr. Tilman calls the link between diet, the environment and human health, “a dilemma”, a situation where it is very difficult to decide what to do. He says one possible solution is leaving the Western diet behind.
【1】Why did people get fatter in the 1960s?
A. They ate foods high in calories.
B. They adopted a western lifestyle.
C. They set aside little time for exercise.
D. They had a better life and became lazier.
【2】According to the text, overweight people may suffer the following diseases EXCEPT_______.
A. diabetes B. skin disease
C. cancers D. heart disease
【3】What is the purpose of the author in writing this passage?
A. To tell people effective ways to keep healthy.
B. To call on people to give up the Western diet.
C. To show the problems industrialized nations are facing.
D. To draw people’s attention to environmental protection.
28、 Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone makers include in the small print that is often ignored when a new phone is purchased Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters.
If health issues arise from cell phone use, the possible effects are huge. According to Devra Davis, an expert who has worked for the University of Pittsburgh, brain cancer is a concern. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20—29 age group and a drop for the older population.
“Most cancers have many causes,” she says, but she points to laboratory research that suggests low energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out: Radiation that penetrates(穿透)only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls(头骨)are thinner and their brains contain more absorptive(易吸收的)fluid.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the belly(腹部).
【1】Why is the warning in the small print?
A.They think people will not mind it. B.The warning is not important at all.
C.They don’t want the users to notice it. D.There is too little space for the warning.
【2】What does the underlined word “vulnerable” in the 4th paragraph probably mean?
A.elegant B.sensitive
C.dynamic D.relevant
【3】Why do children easily be affected by radiation?
A.Because they don’t know about such dangerous radiation.
B.Because they enjoy using cell phones more often than adults.
C.Because they are not strong enough to fight against radiation.
D.Because their skulls are thinner and their brains are easily hurt.
29、 Scientists say they have used artificial intelligence (AI) to create music to represent the protein structure of the novel coronavirus.
Researchers used machine-learning methods to make the music, which may help them better understand the virus. The research team assigned musical notes to amino acids (氨基酸) that make up the so-called “spiked(刺突)” protein that infects human cells. Machine learning was then used to turn the protein and structural information into a nearly two-hour piece of classical music.
Markus Buehler of the Massachusetts Institute of Technology (MIT) led the research team. Buehler told the Reuters news agency that turning the protein data into music let people gain a better understanding of something they cannot see. “You would need many different images, many different magnifications (放大) to see with your eyes, while your ears can pick up with just a couple of seconds of music,” he said.
The finished selection was uploaded to the music sharing website SoundCloud. Listeners of the early part of the piece described it with words such as “beautiful”, “interesting”, “calm” and “nature”. Buehler said this part of the music represents the ease at which the spiked protein enters the human cell, making the coronavirus highly infectious. He noted that the virus is very good at “tricking the cell to open the doors” to infect someone. As the virus then reproduces and the spiked protein attaches to more cells, the music becomes louder, faster and more intense. One SoundCloud user noted that this part could represent one of the first signs of the virus in humans, a high body temperature. Others described the more intense part of the music as “scary” and “sad”.
The researchers say a possible next step could be to use the musical method to design an antibody to attack the virus.
【1】What does the underlined word “tricking” mean in paragraph 4?
A.Cheating. B.Forcing. C.Stopping. D.Helping.
【2】How did Sound Cloud users feel about the second part of the music?
A.Happy. B.Encouraged. C.Disappointed. D.Upset.
【3】What can we learn from the passage?
A.Researchers composed the music on their own.
B.Music may improve our understanding of the virus.
C.Musical method has been applied to attack the virus.
D.SoundCloud users had the same reaction to the whole music.

34、Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
Driving an electric car 【1】 to the protection of environment, or so the marketing departments of their makers would have you believe. Yet a report which analyzes car emissions presents a rather different picture. A battery-powered car recharged with 【2】 generated by coal-fired power stations, it found, is likely to be more harmful. It could cause more than three times as many deaths from pollution as a 【3】 petrol-driven vehicle.
The study was carried out by the University of Minnesota. The researchers estimated how levels of fine particulate matter (细颗粒物) and ground-level ozone — two important 【4】 of air pollution — would change when a car is powered by different ways.
It was no surprise that electric cars whose batteries were recharged with power from wind, solar or hydro-electric sources came out to be virtually free from harmful 【5】. They were estimated to cause 231 deaths over the course of a year, compared with 878 for petrol cars. Electric cars recharged with power from natural gas-fired stations were also a lot less harmful than petrol-driven ones, with 439 deaths. But if those same electric cars were recharged 【6】 by coal, they would be responsible for over 3,000 deaths.
Biofuels also caused more health problems than petrol. But diesel, which often 【7】 concern about pollution, is slightly cleaner than petrol. This is because the study assumes for all cars that emission-control technologies will be more widely used, especially particulate filters which have a remarkable effect on cleaning diesel 【8】. Diesel cars are also more 【9】 of fuel than petrol-driven ones.
Overall, the study shows that electric cars are cleaner than those traditional vehicles only if the power used to charge then is also clean. That is hardly a surprise, but the 【10】 of the difference is. How green electric cars really are, then, will depend mainly on where they are driven. In France, which obtains more than half of its power from nuclear station, electric cars look like a good bet. In China and some other developing countries, where a large amount of electricity is produced from coal, they may not be so environment- friendly as they are marketed.
35、
Rapidly advancing technology and its impact on education has been a subject of debate. How can schools equip students with the skills they need to succeed in a challenging job market?
Since technology is driving these changes, there is a theory that governments should keep focusing on STEM subjects. These are often referred to as “hard skills,” which are 【1】 in primary school and right through to university level. In the meantime, ‘soft skills’ are being 【2】.
This is a mistake. Much evidence suggests that soft skills are far more 【3】 to graduates in the long term. Research from Harvard University on the global job market has shown that STEM- related careers grew strongly between 1989 and 2000 but have slowed down since. In contrast, jobs in the creative industries----the sector probably most 【4】 with the need for soft skills---are growing rapidly. Soft skills are, in fact, increasingly in demand in the workplace: Google cites creativity, leadership 【5】 and communication skills as top requirements for both potential and current employees.
So why are soft skills so highly 【6】 for?
With the rapid evolution of technology, a focus on hard skills leaves students 【7】 to change, as these often have a short shelf life. According to research by World Economic Forum, more than one in four adults reports a mismatch between their skills and those needed for their job role. If soft skills are taught well, these skills should enable students to adapt to change more easily and progress further in their 【8】 career.
Of course, technical skills are important. But without the curriculum placing equal--- if not greater --- 【9】 on soft skills, our education systems are missing a huge trick. Hard skills may help a student get a job in a particular industry, but soft skills will help them disrupt it, achieving a wider 【10】 in their chosen field.

Knowledge is free on the Internet at a small but 【1】 number of colleges and universities. About 160 schools around the world now put free course materials on the web to the 【2】. Recent additions in the United States 【3】 projects at Yale, Johns Hopkins and the University of California, Berkeley.
Berkeley said it would offer videos of lectures on YouTube. Free videos from other schools are 【4】 at the Apple iTunes store.
The Massachusetts Institute of Technology (MIT) became an early 【5】 with its Open Course Ware project, first 【6】 in 2001. Free lecture notes, exams and other resources are published at ocw.mit.edu. Many exams even include the answers. Today, Open Course Ware offers materials from 1,800 undergraduate and graduate courses. These 【7】 from Physics to Political Science. Visitors can learn the same things as MIT students learn. But as the site points out, Open Course Ware is not an MIT education. Visitors receive no credit toward a degree. Some materials from a course may not be available, and the site does not provide 【8】 with teachers. Still, MIT says that the site has had forty million visits by thirty-one million visitors from almost every country. Sixty percent of the visitors are from outside the United States and Canada. Students and educators use the site, including students at MIT. But the largest number of visitors, about half, are self-learners.
Some professors have become well-known around the world as a result of 【9】 online. Walter Lewin, a physics professor at MIT, is 【10】 popular. Fans enjoy his entertaining lectures.
