21、 Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs
A second study, looking at nearly 1,000 grown-ups in New Zealand, found lower education levels among 26-year–olds who had watched lots of TV during childhood. But the results don’t prove that TV is the cause and don't rule out that already poorly motivated youngsters (年轻人）may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2 1/2 hours for those who had no education beyond high school.
In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest.
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn't have TVs in their bedrooms.
【1】According to the California study, the low-scoring group might _________.
A. have watched a lot of TV
B. not be intersected in math
C. be unable to go to college
D. have had computers in their bedrooms
【2】What is the researchers' understanding of the New Zealand study results?
A. Poorly motivated 26-year-olds watch more TV.
B. Habits of TV watching reduce learning interest.
C. TV watching leads to lower education levels of the 15-year-olds.
D. The connection between TV and education levels is difficult to explain.
【3】What can we learn from the last two paragraphs?
A. More time should be spent on computers.
B. Children should be forbidden from watching TV.
C. 'IV sets shouldn't be allowed in children's bedrooms.
D. Further studies on high-achieving students should be done
【4】What would be the best title for this text?
A. Computers or Television
B. Effects of Television on Children
C. Studies on TV and College Education
D. Television and Children's Learning Habits
【5】What does the word “accumulating” in the last paragraphy mean?
A. withdraw B. underline
C. increase D. tolerate
22、The scientists who re-engineered the plastic-eating enzyme (酶) PETase have now created a new enzyme called “cocktail”, which can digest plastics up to six times faster.
PETase breaks down PET back into its building blocks, creating an opportunity to recycle plastics and reduce plastic pollution. PET is the most common thermoplastic (热塑性塑料) used to make single-use drink bottles and it takes hundreds of years to break down in the environment, but PETase can shorten this time to days. The initial discovery set up the prospect of a revolution in plastic recycling, creating a potential low-energy solution to deal with plastic waste.
Now, the same trans-Atlantic team have combined PETase and its “partner”, a second enzyme called MHETase, to generate much bigger improvements: simply mixing PETase with MHETase doubled the speed of PET breakdown, and engineering a connection between the two enzymes to create a “super-enzyme” increased this activity by a further three times.
The team was co-led by the scientists who engineered PETase, Professor John McGeehan and Dr Gregg Beckham. Professor McGeehan said: “Gregg and I were chatting about how PETase attacks the surface of the plastics and MHETase chops things up further, so it seemed natural to see if we could use them together. Our first experiments showed that they did work better together, so we decided to physically link them. It took a great deal of work, but it was worth the effort -we were delighted to see that our new enzyme is up to three times faster than the separate enzymes.”
The original PETase enzyme discovery indicated the first hope that a solution to the global plastic pollution problem might be within grasp, though PETase alone is not yet fast enough to handle the tons of PET bottles. Combining it with a second enzyme, and finding together they work even faster, means another leap forward has been taken towards finding a solution to plastic waste. PETase and the new combined MHETase-PETase both work by digesting PET plastic. This allows for plastics to be made and reused endlessly, reducing our reliance on fossil (化石) resources.
【1】What can we learn about “cocktail” from the text?
A．It doubles the breakdown of plastics.
B．It takes hundreds of years to break down.
C．It deals with plastic waste three times faster.
D．It contributes to breaking down plastics quickly.
【2】What is the second paragraph mainly about?
A．A new study of PET.
B．The breakdown of PET.
C．The discovery of PETase.
D．The function of PETase.
【3】What can we learn from paragraph 4?
A．Combining PETase and MHETase works better than separate ones.
B．Conducting experiments requires no diligent work.
C．PETase chops things up further.
D．MHETase attacks the surface of the plastic.
【4】What can we infer from the text?
A．PET pollution is no longer a difficult problem to deal with.
B．The new enzyme is speeding up our reliance on fossil resources.
C．MHETase-PETase makes the world free from plastic pollution.
D．Plastic-eating enzyme “cocktail” promises new hope for plastic waste.
23、 More than 2,000 years ago, when the last shovelful(一铲) of dirt fell on the Tarracotta Warriors, it was thought that they would never see the sunlight again and would spend the rest of their “lives” guarding and protecting the first Chinese emperor, Qinshihuang, who died in 210 BC.
But things got better off these clay soldiers. Ever since they were discovered in Xi’an in 1974,by a group of farmers; they’ve been able to see the bigger world-traveling from one museum to the next.
They are now on display in New York at Discovery Times Square, reported the New York Times.
However, the story doesn’t end here. The roughly 2,000 soldiers found so far are estimated to be only one quarter of the total number. Moreover, scientists haven’t yet dared to touch the central tomb, which is believed to contain the body of the emperor himself.
“Partly it’s out of respect for the elders,” explained Kristin Romey, consultant for the exhibition. “But they also realize that nobody in the world right now has the technology to properly go in and excavate(挖掘) it.”
This is true. According to ancient writings, the emperor’s tomb is circled by rivers of liquid mercury(水银) which is highly poisonous but can keep the body in good condition. Studies of the soil around the tomb also found a large amount of mercury. This makes exploring the tomb very dangerous.
The other reason that scientists have been hesitating is that they are afraid of the damage they might cause by opening the tomb.
“When we began excavating ‘the soldiers’, the minute they were exposed to air and sunlight, the pigment(颜料) just flaked off (剥落),” Romey told the Fox News.
But he believes that the solution will come when science advances. Perhaps a visual robot can be sent into the tomb first to investigate and help figure out the best way to protect it.
In the end, scientists and historians must weigh their desire to know against the damage their digging might cause. “Archaeology, ultimately (最终),is a destructive science,” Romey said. “You have to destroy stuff in order to learn about it.”
【1】What is the point of the article?
A.To tell about the mysteries of Qinshihuang’s tomb.
B.To analyze why archaeology is a destructive science.
C.To explain the risks of further excavating Qinshihuang’s tomb.
D.To introduce the Terracotta Warriors exhibition in New York.
【2】What can be concluded from the article?
A.The decision whether to open the tomb or not is likely to be influenced by the pace of technological progress.
B.It is estimated that about 10,000 clay soldiers were buried with Qinshihuang in his grave.
C.The highly poisonous mercury was used by Qinshihuang to keep away those who attempt to destroy his tomb.
D.Scientists won’t excavate Qinshihuang’s tomb until they think of a good way to preserve the body of the emperor.
【3】The underlined word “investigate” in the second-to-last paragraph probably means________.
A.settle down B.arrange
C.take over D.explore
【4】What should scientists and historians pay attention to in their work according to the article?
A.They should respect the ancient world during their work.
B.They should balance the value and damages of their work.
C.They should always take their own safety into consideration.
D.They should have a continuous desire to know new things.
24、To take the apple as a forbidden fruit is the most unlikely story the Christians ever cooked up. For them, the forbidden fruit from Eden is evil(邪恶的). So when Columbus brought the tomato back from South America, a land mistakenly considered to be Eden, everyone jumped to the obvious conclusion. Wrongly taken as the apple of Eden, the tomato was shut out of the door of Europeans.
What made it particularly terrifying was its similarity to the mandrake, a plant that was thought to have come from Hell(地狱 ) What earned the plant its awful reputation was its roots which looked like a dried-up human body occupied by evil spirits. Though the tomato and the mandrake were quite different except that both had bright red or yellow fruit, the general population considered them one and the same, too terrible to touch.
Cautious Europeans long ignored the tomato, and until the early 1700s most of the Western people continued to drag their feet. In the 1880s, the daughter of a well-known farmer wrote that the most interesting part of an afternoon tea at her father's house had been the "introduction of this wonderful new fruit--or is it a vegetable? ""As late as the twentieth century some writers still classed tomatoes with mandrakes as an "evil fruit".
But in the end tomatoes carried the day. The hero of the tomato was an American named Robert Johnson, and when he was publicly going to eat the tomato in 1820, people journeyed for hundreds of miles to watch him drop dead. "What are you afraid of? "he shouted. "T"ll show you fools that these things - are good to eat! Then he bit into the tomato, Some people fainted. But he survived and, according to a local story, set up a tomato-canning factory.
【1】The tomato was shut out of the door of early Europeans mainly because__________.
A. it was religiously unacceptable B. it was the apple of Eden
C. it came from a forbidden land D. it made Christian evil
【2】What can we infer from the underlined part in Paragraph 3?
A. The process of ignoring the tomato slowed down.
B. The tomato was still refused in most western countries.
C. There was little progress in the study of the tomato.
D. Most western people continued to get rid of the tomato.
【3】What is the main reason for Robert Johnson to eat the tomato publicly?
A. To make himself a hero.
B. To persuade people to buy products from his factor.
C. To speed up the popularity of the tomato.
D. To remove people's fear of the tomato.
【4】What is the main purpose of the passage?
A. To present the change of people' s attitudes to the tomato.
B. To give an explanation to people's dislike of the tomato.
C. To challenge people's fixed concepts of the tomato.
D. To show the process of freeing the tomato from religious influence.
25、 Could Buying Paintings Make You Rich?
Is investing in paintings a good way to get rich fast? And how should you invest in art?
“With extreme _______” is the advice of Patrick Connolly, a financial adviser. “We don’t _______ our customers to invest in art because the downsides are greater than the upsides. It doesn’t produce income or earnings. What you _______ is exclusively based on supply and demand, and there are big movements upwards or downwards if there are changes in the economic environment,” he said.
To invest in art as a true investment, you need a starting fund of at least $5,000. But it’s not just about having enough _________ to buy the painting in the first place. Expensive works of art are often stored in protective boxes complete with detectors to monitor humidity and temperature levels, and to protect them from sun damage or other _______ such as a spilled cup of coffee. And if you do put it on your wall, then your insurance costs are likely to be high. If word gets out that you have expensive art hanging on your wall, then you’re likely to be a _______ for thieves.
Art is also not a regulated investment so when things go wrong — for example, an artwork turns out to be a fraud (赝品) — then investors cannot fall back on _______ for any repayment.
Of course given the current environment of low interest rates, that’s still a(n) _______ return than many savings accounts will give you. As art has no association to the stock market, it means paintings can _______ in value even when the market crashes, making it a good option for investment __________.
It is reported that after a decrease in the global art market throughout 2016, auction (拍卖) sales __________ in the first six months of 2017. Yet you don’t necessarily have to be super-wealthy to invest in art. There are a growing number of art fairs and online marketplaces aimed at buyers with a more __________ budget. Most art industry experts suggest that you buy a piece of art because you like it, not because you want to get rich. The most __________ approach is probably to buy something you like and can __________ and, be prepared to keep it just for your own pleasure. If it goes up in value that should be just a(n) __________ benefit.
