26、   For most of us, there is no debate — bananas are yellow. Color isn’t as objective as you might think though. Our brain decides what color we are looking at based on the light that comes into our eyes, and how we see colors actually varies a lot.

There are many ways color can confuse our brains. Positioning and shading can change what we think we are looking at. Two people can see the same thing very differently because of how our brains deal with light.

How we see color, however, is governed by much more than just our bodies. Our emotions or even the time of year, can change how our eyes and brains react to what we see. Yellow looks different to us depending on the season, according to scientists at the University of York. In the summer yellow appears more “greenish” whereas in the winter yellow appears more “reddish”. This is the result of living in an environment where the level of green light increases in the summer. When the trees are full of leaves, our eyes need to adapt. With extra green all around us, our brain has to recheck its understanding of yellow.

Researchers in Rochester, New York have found that feeling sad can impact on your ability to identify (辨别) colors. Participants were shown some small pieces of cloth which had most, but not all, of the colors removed from them. Later, they were asked to identify what color they were looking at. A group who had watched the death of Mufasa in The Lion King found it harder to pick out blue and yellow than others who had not seen the film. Psychologists believe that dopamine — which controls our brain’s reward and pleasure centers — has an impact on how we identify these colors. So while color might seem to be one of the simplest things in our world, it is actually a mystery scientists are only just beginning to solve.

【1】What does the passage mainly focus on?

A.Why we see colors differently. B.How our brains receive colors.

C.Why colors affect our emotions. D.How people can identify colors.

【2】Which of the following is unable to affect people’s ability to identify colors?

A.Position. B.Intelligence.

C.Environment. D.Feeling.

【3】Yellow looks different in summer and winter because of ___________.

A.people’s different sight B.the different temperatures

C.the different levels of green light D.people’s different body conditions

【4】What can we learn from the last paragraph?

A.The sad feeling weakens people’s ability to identify colors.

B.We can find out the secret of dopamine in some movies.

C.Scientists have found the answer to the color mystery.

D.There are many ways that color can entertain our brains.

27、Reading poetry is an art in itself. Whether you’re reading someone else’s poem or your own, how you read the poem can affect the meaning. If you need to read a poem in front of others, you need to take steps to read it well. 【1】

Stand up straight. When you’re reading a poem in front of people, you need to show confidence. 【2】 Instead, you should stand up straight with your shoulders back, so that you can exude (散发) confidence, even if you’re not feeling confident.

Make eye contact (接触). 【3】 However, it’s important to know your poem well enough so that you can look up from time to time to make eye contact with the audience. It both attracts the audience and helps you show confidence.

Add proper movement. Movement can help make a poem better accepted, but only if you do it properly. 【4】 If it’s a very serious, natural poem, you may not want to use any movement at all. If it’s a more playful poem, movement may be more proper.

【5】 When you’re in a room, make sure you are heard by all in the room. Those people in the far back need to hear, so you will often need to read louder than you normally do. If you’re not sure how loud you need to speak, you can always ask if the people in the back can hear you.

A．Project (投射) to the whole room.

B．Read the poem in the loudest voice.

C．You can’t make eye contact all the time while reading.

D．Eye contact shows that you are confident to use movement.

E．Particularly, you need to pay attention to your body language.

F．If you stand with your head down, that shows a lack of confidence.

G．Think about the poem itself to determine how much movement is proper.

28、Stephen Warren, study leader at the University of Washington, has been on the case of the green icebergs for more than 30 years. He first took samples from one of these green hunks of ice in 1988, near the Amery Ice Shelf, East Antarctic. Most glacial ice occurs in shades of white to brilliant blue. The bluer the ice, the older it is. Typically, compression (压缩)from accumulating layers of snow pushes air bubbles out of the ice, reducing the scattering of white light. The compressed ice absorbs most of the light except for blue, creating the blue color seen in the hearts of icebergs and glaciers.

The green ice was similarly bubble-free, and yet it looked green instead of blue. Warren and his team soon found that the green ice came not from glaciers, but from marine ice. That's the ice from the undersides of floating ice shelves.

At first, the team thought that organic material in the marine ice was causing the green color. But further research showed that the green marine ice didn't have a higher — than — usual amount of organic impurities. Now, a new study finds that a different sort of impurity may be the root cause of the green ice. Warren and his colleagues report that the marine ice at the bottom of the Amery Ice Shelf has 500 times more iron than the glacial ice above.

This iron comes from the rocks under the Antarctic Ice Sheet, which are turned into fine powder as glaciers move over them. The icebound iron oxidizes (氧化)as it contacts seawater. The resulting iron oxide particles take on a green color when light scatters through them. When icebergs break off the larger ice shelf, they carry this iron-rich ice with them. It's like taking a package to the post office. The iceberg can deliver this iron into the ocean far away, and then melt and deliver it to other living things that can use it as a nutrient.

【1】What's special about the iceberg found by Warren?

A．The iceberg was old.

B．The iceberg absorbed blue light.

C．The iceberg's heart was pure white.

D．The iceberg was bubble-free and green.

【2】What's the actual reason for the green color of some Antarctic icebergs?

A．Impurities of marine ice.

B．Reflection of green plants.

C．Iron dust from marine ice.

D．Compression from layers of snow.

【3】What's the function of the iron mentioned in the last paragraph?

A．Deliver the package.

B．Bring marine life nutrients.

C．Oxidize the seawater.

D．Break off the large ice shelf.

【4】What can be a suitable title for the text?

A．A Study About Antarctic

B．The Colors of Icebergs

C．The Movement of the Icebergs

D．The Mystery of the Green Icebergs

29、Nobel prize-winners, legendary(传奇的)authors, and famous scientists—you might think all these people were born to be creative. However, that’s not always the case.

While well-known figures like Pablo Picasso and Albert Einstein did their most significant work in their youth, famous American poet Robert Frost and English-born natural scientist Charles Darwin were known as “late bloomers” —people whose talents were not noticeable until later in life.

This idea of “peaking” at different times inspired new research from the United States. “Many people believe that creativity is exclusively(独有地)associated with youth, but it really depends on what kind of creativity you’re talking about,” said Bruce Weinberg, a professor of economics at the University of Chicago and co-author of the study.

According to the study, published earlier this month in the journal De Economist, there are two types of people: conceptual(概念的)and experimental thinkers.

To reach this conclusion, researchers took the 31 previous winners of the Nobel Prize in economics and arranged them according to when they did their most significant work, to identify their creative peaks.

Some peaked from ages 25—29. Classified as conceptual thinkers, these people think outside of the box, coming up with new ideas before they become used to the conventional way of doing things.

The second creative peak came with economists in their 50s. These are experimental thinkers who have been in their fields for a long time. This allows them to learn from errors and experiment with different processes, before eventually finding new solutions.

“Whether you hit your creative peak early or late in your career depends on whether you have a conceptual or experimental approach,” said Weinberg. He added that their study isn’t limited to economics, saying it can apply to other creative disciplines(知识领域). So if you’re struggling to come up with new ideas, don’t panic. Your creative peak may be yet to arrive.

【1】What did the study from the US find?

A．Young people are not necessarily more creative than old people.

B．Most people take a conceptual approach when thinking.

C．People’s creative peak in their life is related to their job type.

D．Conceptual and experimental thinkers hit their peaks at different times.

【2】What is the characteristic of conceptual thinkers?

A．They tend to challenge conventional rules.

B．They are creative due to their young ages.

C．They are likely to follow traditional rules.

D．They fail to come up with new ideas.

【3】What do we know about experimental thinkers?

A．Their talents usually bloom in their 20s.

B．They are good at doing experiments.

C．They work out new methods based on experience.

D．They are more successful than conceptual thinkers.

【4】What would Weinberg probably agree with?

A．It’s difficult to find one’s talent in later years.

B．More research needs to be done about creative peaks.

C．Conceptual thinkers could be more successful in the art field.

D．Experimental thinkers from other fields may succeed in their 50s.

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.

36、Directions: Read the following passage. Fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word. For the other blanks, use one word that best fits each blank.

My daughter

(A story told by a father, a famous actor)

My wife and I only had the one child. We had Amy.

I see her as my best friend. I think she’d always come to me first if she had a problem. We have the same sense of humor, and share interests. 【1】 I don’t mind animals, she’s completely fascinated with them, and she has always had dogs, cats, horses, and goldfish in her life.

We were 【2】 (close) when she was about four, which I think is a lovely age for a child. They know the parents best, and don’t have outside contacts. She must have grown up suddenly when she went to school, because I remember her growing away from her family slightly. Any father who has a teenager daughter comes across an extraordinary collection of people, and there seemed to be an endless stream of strange young men 【3】 (come) through our house. By the time I learned their names they 【4】 (go) away and I had to start learning a new lot.

I wanted more than anything else for her to be happy in 【5】 she was doing, and I was prepared to pull strings to help her on her way. When she left a good school she decided she wanted to become an actress so I got her into drama school. It wasn’t to her liking so she joined a theatre group and began doing bits and pieces in films. She was doing well, but then gave it up. She probably found it boring. Then she took up social work, and finally went to work 【6】a designer and he became her husband. And that’s really the story of her life. She must be happy with him—they’re always together.

We have such similar tastes in books and music 【7】 I used to take her to see an opera, which is my big passion. However, I don’t think she likes it very much. She doesn’t come with me anymore.

I don’t think she’s a big television watcher. She knows when I’m on the television, and she 【8】 watch, but I don’t know. It’s not the kind of thing she tells me.

We’re very grateful for Amy. She’s a good daughter as daughters go. We’re looking forward to being grandparents.

Even though the update still won’t recognize your masked face, it makes the whole process f【7】. While the old system wouldn’t allow access t【8】 the passcode screen before three failed face scan attempts, iOS13.5 will send you straight to the passcode screen when you swipe up.

It might only s【9】 you a few seconds, but those few seconds “benefit public health by eliminating the temptation for people to r【10】 their masks in order to unlock their device”.

38、阅读下面短文，根据其内容写一篇60词左右的内容概要。

You may know that vitamin C is important to your body，but do you know that vitamin D is important to your body as well? Vitamin D has a significant role in calcium homeostasis(钙稳态) and metabolism(新陈代谢). It is sometimes called the “sunshine vitamin” because it’s produced in your skin in response to sunlight.

Vitamin D can help bones and muscles grow strong and healthy. If a person is short of vitamin D，he or she may have problems like rickets(佝偻病) and osteoporosis．Rickets is mainly found in children. Osteoporosis，the thinning of bone，is a common problem as people get older. Studies in these years have found that vitamin D may also have other uses. If someone is short of vitamin D, he may have heart problems or die from some cancers.

The easiest way to get vitamin D is from sunlight. But many people worry about getting skin cancer and skin damage from the sun. Also, even skin color has an influence. Darker skinned people get less vitamin D than lighter skinned people. Older people get less vitamin D than younger people. You can also get it from foods. Some food such as cheese and egg yolks (蛋黄) have some vitamin D．But most of vitamin D in the American diet comes from food like milk with the vitamin added.

Now more doctors are testing for vitamin D in their patients. However, some doctors worry that if people take too much vitamin D, it might be bad for their body. At the same time, skin doctors tell people to be careful with strong sunlight.
