21、Some scientists win the Nobel Prize for their work. Other scientists win the “Ig Nobel” Prize, which honors real science that is so strange. “We want to make people laugh and then think,” says Ig Nobel founder Marc Abrahams. He and his colleagues pick 10 of the world’s strangest scientific studies on subjects like Physics Biology, Medicine, and so on, to honor each year. Here are two of the strangest Ig Nobel winners since the prize was founded 26 years ago:
No-blink photos, almost guaranteed.
Why is someone always blinking(眨眼)in your photo?Science says: because you don’t take enough pictures.
Winner, 2006 Mathematics Ig Nobel:
An Australian photographer wondered how many group shots she should take to be pretty sure no one was blinking. She found ou you need to divide the number of people by 2 to figure it out. Twelve people?Take at least six photos. But with groups over 50, someone will always be caught blinking no matter how many photos you take.
The five-second rule is true—sometimes.
Have you ever dropped food on the floor, said, “Five-second rule!” then picked it up and eaten it? The idea is that bacteria won’t stick if you pick it up quickly.
Winner, 2005 Public Health Ig Nobel:
Jillian Clark was still in high school when she did her winning research on the five-second rule. She dropped foods on the floor and then studied the bacteria they picked up in five seconds. Her discovery? If the floor is clean, the food is safe to eat. But how clean is your floor? You need a powerful electron microscope to know for sure.
【1】Why was the “Ig Nobel” Prize founded?
A. To promote laughter and thought.

22、 A team of scientists says that playing sounds underwater can get fish to return to areas with severely damaged coral reefs(珊瑚礁）.
In an experiment, they found fish returned after hearing recordings of the sounds of a healthy ocean reef. The scientists placed underwater speakers in areas where coral had been dying in Australia’s northern Great Barrier Reef. They played the sounds over a period of about six weeks in 2017 and studied the results. The team reported that twice as many fish arrived in areas where the sounds of healthy coral were played.The sounds also led to a 50 percent increase in the number of species present in the area, the researchers found. Among the arriving fish were species that feed on all major food sources.
The researchers noted the importance of having many different kinds of fish return to the area. Different species of fish perform many activities that support the ocean environment and sea life. “Damaged reefs have a higher chance of recovery if they have healthy fish populations,” the scientists wrote in the report.
Steve Simpson is a professor at the University of Exeter who helped lead the research. He said in a statement that “healthy coral reefs are remarkably noisy places. ” They contain the sounds of many kinds of shrimp, fish and other sea creatures. Young fish listen for these sounds when they are looking for a place to settle, Simpson said.
He added that reefs “become ghostly quiet” when they suffer destruction that is usually related to human-caused pollution. Coral damage can cause unappealing smells and sounds that drive shrimp and fish away. But the experiment suggested that the use of underwater loudspeakers was an effective way to get young fish to come back.
Andy Radford, a professor at University of Bristol,said the underwater sounds are a promising way to fight coral reef damage at the local community level. But he noted that other threats need to be, reduced as well. These include climate change, pollution and overfishing.
【1】What did the scientists find in the experiment?
A.Twice as many fish arrived in the healthy coral areas.
B.The sounds led to a 50 percent increase in the number of fish present in the area.
C.Playing the sounds of healthy coral reefs is effective to save dying coral.
D.Damaged reefs can recover completely if they have healthy fish populations.
【2】According to Steve Simpson,what will drive fish away from damaged coral reefs?
A.Human-caused pollution.
B.The unattractive smells and sounds.
C.Climate change.
D.Overfishing.
【3】What’s the main idea of the text?
A.Healthy fish help recover the damaged coral reefs by swimming.
B.People reduce environmental pollution to save dying coral.
C.Scientists find a new way to protect the ocean environment and sea life.
D.Researchers use underwater sounds to fight coral reef damage.
23、 Ownership used to be about as straightforward as writing a cheque. If you bought something, you owned it. If it broke, you fixed it. If you no longer wanted it, you sold it or threw it away. In the digital age, however, ownership has become more slippery. Since the coming of smartphones, consumers have been forced to accept that they do not control the software in their devices; they are only licensed to use it. As a digital chain is wrapped ever more tightly around more devices, such as cars and thermostats, who owns and who controls which objects is becoming a problem. Buyers should be aware that some of their most basic property rights are under threat.
The trend is not always harmful. Manufacturers seeking to restrict what owners do with increasingly complex technology have good reasons to protect their copyright, ensure that their machines do not break down, support environmental standards and prevent hacking. Sometimes companies use their control over a product's software for the owners' benefit. When Hurricane Irma hit Florida this month, Tesla remotely updated the software controlling the batteries of some models to give owners more range to escape the storm.
But the more digital strings are attached to goods, the more the balance of control leans towards producers and away from owners. That can be inconvenient. Picking a car is hard enough, but harder still if you have to dig up the instructions that tell you how use is limited and what data you must give. If the products are intentionally designed not to last long, it can also be expensive. Already, items from smartphones to washing machines have become extremely hard to fix, meaning that they are thrown away instead of being repaired.
Privacy is also at risk. Users become terrified when iRobot, a robotic vacuum cleaner, not only cleans the floor but also creates a digital map of the inside of a home that can then be sold to advertisers (though the manufacturer says it has no intention of doing so). Cases like this should remind people how jealously they ought to protect their property rights and control who uses the data that is collected.
Ownership is not about to go away, but its meaning is changing. This requires careful inspection. Devices, by and large, are sold on the basis that they enable people to do what they want. To the extent they are controlled by somebody else, that freedom is compromised.
【1】What benefit does it bring to customers if companies control the ownership of products?
A.It provides them with knowledge to prevent hacking.
B.It gives them the chance to be protected from danger.
C.It enables them to own the copyright of the products.
D.It helps them know more about complex technology.
【2】The underlined words "that freedom" in the last paragraph refer to the freedom to ________.
A.control other people B.share the ownership
C.inspect devices at any time D.use devices as one wishes
【3】The author may agree ________.
A.customers should buy fewer digital devices
B.producers should control property rights
C.property rights need to be protected
D.better after sales service is required
【4】Which of the following shows the development of ideas in the passage?
I: Introduction P: Point Sp: Sub-point (次要点) C: Conclusion

24、He was wandering in a rice field of dreams. 【1】 After walking a while he lay down in the leaf-shade with a friend, quite hidden. A rest was a good idea, because the wonder-plants went on and on. In fact, they covered the world.
Then Yuan Longping woke up, laughing. 【2】. But they still deserved their name of super rice. The leaves were straighter and taller than ordinary, and the grains plumper. They had all the vigor of the wild strain that he and his team had found after much searching and had cross-bred, over careful years, with the domesticated variety.
The figures spoke for themselves. 【3】. In Yunnan province more than 17000 kilograms had been produced per hectare. China’s rice crop had risen from 57m tonnes in 1950 to 195m in 2017; from food deficiency, to food security. Higher rice-yields allowed farmers to turn more land to other uses-fruit, vegetables, fishponds-so that people ate more and well.
For this he won the Medal of the Republic, China’s highest, and the World Food Prize. An asteroid was named after him. There was talk of the Nobel, too. 【4】. Though he was rich, from his shares in a seed company that used his name, he looked like a peasant, thin as a twig, with his face leathered by sun and his big hands rough from “playing in the mud” all day.
He was far happier in his short-sleeved work-shirts, out in his rice, or stripped off swimming in any wild river he could find, than in a tang suit in some conference hall.
A．Nothing but the continuous development of his beloved country seemed to attract him
B．With his new hybrid rice the annual yield was 20-30% higher, so at least 60m more people could be fed every year.
C．His dreams focused on his people and his country, where all enjoyed food and wealth.
D．All that seemed just smoke to him.
E．The plants were taller than men. Each grain is as big as a peanut.
F．The rice plants he had tended for decades at Anjiang and then Changsha, sowing and nurturing them, visiting daily on his motorbike to inspect them, were not quite there yet.

26、Directions: Read the following three passages. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and cause emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not receive day care before the age of three because of the parental separation it results in, and many people do believe this. But there are also arguments against such a strong conclusion.
Firstly, authropologists（人类学家）point out that the isQulated love affair between children and parents found in modern societies does not usually exist in traditional societies. For example, we saw earlier that among the Ngoni（恩戈尼人）the father and mother of a child did not raise their infant alone - far from it.
Secondly, common sense tells us that day care would not be so widespread today if parents, caretakers found children had problems with it. Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial.
Thirdly, in the last decade, there have been a number of careful American studies of children in day care, and they have reported that day care had a slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.
But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early is reasonable for infants.
