21、 A freshly baked roll is as delightful as a soft，light cloud on a summer's day.What gives bread much of its appealing texture is gluten，a group of proteins found in wheat.But in people with celiac disease(乳糜泻)，gluten damages the small intestine(肠).Many others may have milder gluten intolerance and avoid foods that contain it.
Most gluten-free bread is made from alternative flours such as rice or potato，so it tastes and feels different from wheat bread.Now，however，researchers say that they have found a way to genetically engineer wheat that contains far less of the most troublesome type of gluten—but still has other proteins that give bread its characteristic taste and springiness.
Genetically modified crops are the subject of fierce debate around the world.The biggest concern involves the practice of inserting DNA from one species into another，says Francisco Barro，a plant biotechnologist.To avoid this genetic crossover，Barro and his colleagues used the gene-editing technique CRISPR／Cas9 to cut selected genes from a wheat genome(基因组).
Their study zeroed in on alpha-gliadins(α-胶质蛋白)，gluten proteins believed to be wheat’s major troublemakers in the immune system.The researchers designed bits of genetic material that directed the scissor-like Cas9 protein to cut out 35 of the 45 alpha—gliadin genes.When the modified wheat was tested in a Petri dish，it produced an 85 percent weaker immune response，the team reported online last September in Plant Biotechnology Journal.
Wendy Harwood，a crop geneticist at the John Innes Center in England，who was not part of the study，notes that the engineered wheat has a long way to go before it can be turned into anything marketable.“I don’t think it's the end of the story.”she says.“This is just a really important step in maybe producing something that is going to be incredibly useful.”To develop a completely safe strain of wheat for celiac patients，the researchers may need to target more of the gluten genes.Barro says his team is working on that.

22、 Have you ever been around when the water bill arrives at your house? Perhaps you’ve heard someone say, “Stop wasting water! The water bill is sky high!” Water costs a lot of money. You might be wondering why water is so expensive. After all, water hardly seems scarce. It covers the majority of Earth. However, most of Earth’s water is in salty oceans. Only a small amount of it is drinkable.
All living things need water to survive, so water is one of our most important natural resources. With a little effort, you can save water and also help keep down the water bill. You will be surprised at how easy it is to save water. Read the tips below to learn how.
From the time you wake up until you go to bed, pay attention to how much water you use. Do you wash your hands before you eat breakfast? If you do, turn off the water while you use the soap. Then when you finish washing your hands, make sure you turn the tap off. Also remember to turn it off when you put toothpaste on your toothbrush and while brushing your teeth.
Maybe you take a shower in the morning. Try to keep your time in the shower to less than ten minutes. Installing a low-flow showerhead, which reduces the amount of water you use, will help, too. If you let the water in the shower heat up before you get in, don’t let it go down the drain (排水孔). Instead, catch the water in buckets and use it to water houseplants. Usually, you use much less water in a shower than in a bath. A shower is more refreshing, too. However, if you decide to take a bath, be sure to close the drain before you turn on the water.
There are so many ways to save water. For fun, try to do at least one thing every day to save water. Every drop of water counts!
【1】What does the underlined word “scarce” in paragraph 1 mean?
A．invisible.
B．costly.
C．usable.
D．limited.
【2】How can people save water while showering？
A．By using a low-flow showerhead.
B．By adjusting the water temperature.
C．By turning the water off while using the soap.
D．By closing the drain before turning on the water.
【3】According to the text, which of the following is TRUE?
A．People who take baths do not care about the environment.
B．If people could drink salt water, there would be less need to save water.
C．The biggest waste of water comes from washing hands and brushing teeth.
D．People are not advised to let the water in the shower heat up before they get in.
23、 For some parents, hitting a child who misbehaves is a common punishment. In fact, they may think that a physical type of punishment is good for children and will teach them to behave in the future.
However, a leading group of child health specialists suggest that the opposite is true. These experts say that hitting is not only ineffective, but may even cause long-term harm to the child. The American Academy of Pediatrics recently changed its policy on physical punishment for a child. Released in October, the academy warns that hitting a child may have long-term effects. These effects include “aggression, brain changes, substance abuse and suicidal behavior in adulthood”. The report admits that not every child who is spanked will have these problems later in life. It makes this observation: “Although many children who were spanked become happy, healthy adults, current evidence suggests that hitting is not necessary and may result in long-term harm.”
In recent years, many American experts have been advising parents against the use of physical punishment. Many other countries have already banned corporeal punishment. Sweden was the first nation to do so in 1966. Earlier studies have shown that corporal punishment can also affect a child’s ability to think and learn. In 2012, a Canadian study found that hitting children can cause long-term developmental damage and may even lower a child’s intelligence test scores. The American Academy of Pediatrics also warns against using strong verbal abuse or shame to discipline a child. These types of punishment can also cause long-term problems for a child. Instead, they suggest other types of punishment that are appropriate for the age of the child.
For younger children, punishment could be taking away a favorite toy. For older children, a parent can limit the time the child spends watching television or playing with computers or electronic games.
【1】What can we know according to the experts?
A.Spanking a child is not effective but harmful.
B.Sweden was the first country to spank a child in 1996.
C.The study from Canada found that spanking children can lower children’s grades.
D.Many American experts found spanking a child can cause anti-social behavior.
【2】Which of the following best explains “discipline” underlined in paragraph 3?
A.Protect. B.Control. C.Persuade. D.Punish.
【3】What does the author intend to say in the last paragraph?
A.We should take away younger children’s favorite toys as punishment.
B.As for older children, we need allow them to watch TV or play games.
C.Different children should be given different ways to punish.
D.It may be ineffective for younger or older children to have punishment.
【4】What is the text mainly about?
A.A physical type of punishment.
B.The effects of punishment.
C.Different countries have different types of punishment.
D.How to punish the mischievous children.
24、Thinking is something you choose to do as a fish chooses to live in water. To be human is to think. But thinking may come naturally without your knowing how you do it. Thinking about thinking is the key to critical（批判性的）thinking. When you think critically, you take control of your thinking processes（过程）. Otherwise, you might be controlled by the ideas of others. Indeed, critical thinking is at the heart of education.
The word "critical" here has a special meaning. It does not mean taking one view against another view, as when someone criticizes another person for doing something wrong. The nature of critical thinking is thinking beyond the easily seen—beyond the pictures on TV, the untrue reports in the newspapers, and the faulty reasoning (错误的推理).
Critical thinking is an attitude as much as an activity. If you are curious about life and desire to dig deeper into it, you are a critical thinker; if you find pleasure in deep thinking about different ideas, characters, and facts, you are a critical thinker.
Activities of the mind and higher-order reasoning are processes of deep and careful consideration. They take time, and do not go hand in hand with the fast speed in today's world, fast foods, instant coffee, and self-developing film. If you are among the people who believe that speed is a measure of intelligence, you may learn something new from a story about Albert Einstein. The first time Banish Hoffman, a scientist, was to discuss his work with Albert Einstein, Hoffman was too nervous to speak. But Einstein immediately put Hoffman at ease by saying, "Please go slowly, I don't understand things quickly."
【1】Critical thinking is important to us because if we do not think critically,__________.
A.it will be hard for us to think naturally and fast
B.we will follow the ideas of others naturally
C.we might be controlled by other people's ideas
D.we might be fooled by other people's ideas
【2】If you are a critical thinker, you will________.
A.criticize other people for their mistakes B.trust the reports in the newspapers
C.take one view against another view D.think deeply about different ideas
【3】In the last paragraph, "something new" suggests that________.
A.the smarter you are, the faster you do things
B.intelligence is not decided by speed
C.speed can improve intelligence
D.the faster you do things, the smarter you become
【4】What would be the best title for the passage?
A.Understanding Critical Thinking B.Thinking and Critical Thinking
C.Thinking Natural and Human D.Thinking Fast Means Intelligence
25、The East African country of Kenya has been at the forefront of the global war on plastic since 2017, when officials banned plastic bags. In June 2020, the government ________ the efforts with a ban on single-use plastics in protected areas. Unfortunately, the measures have ________ made any impact. Hundreds of tons of industrial and consumer polymer（聚合物）waste continue to get ________ into landfills daily. However, if 29-year-old Nzambi Matee has her way, the unpleasant plastic ________ will soon be transformed into colourful bricks.
The material engineer’s search to find a(n) ________ solution to control plastic pollution began in 2017. She quit her job as a data analyst at a local chemical factory and set up a small lab in her mother’s backyard. It took her nine months to produce the first brick and even longer to ________ a partner to help build the machinery to make them. But the determined eco-entrepreneur was confident in her idea and did not________.
She says, “I wanted to use my education in applied physics and material engineering to do something about the problem of plastic waste pollution. But I was very ________ that the solution had to be practical, sustainable, and affordable. The best way to do this was by ________ the waste into the construction and finding the most efficient and affordable material to build homes.”
Her company, Gjenge Makers, now hires 112 people and produces over 1,500 bricks a day. The pavers（铺路材料） are made using a mix of plastic products that cannot be reprocessed or recycled. The polymer is obtained ________ from factories or picked by hired locals from Nairobi's largest landfill, Dandora.
The collected plastic is ________ with sand, heated at very high temperatures, and compressed into bricks that vary in colour and thickness. The ________ product is stronger, lighter, and about 30 percent cheaper than concrete bricks.

26、阅读下面材料，根据其内容和所给段落开头语段续写两段，使之构成一个完整的故事。续写的词数为150左右。
When Bryan Anderson noticed an old lady, caught on the side of the road, he knew she needed help. So he pulled up in front of her Mercedes and got out with his motor still running.
Even with a big smile on his face, she was worried. He didn't look safe; he looked poor and hungry. After reading her mind, he introduced himself as Bryan Anderson and began to help her.
Learning that she had a flat tire, without a second thought, Bryan set out to work and took hours to get it right, dirty and tired. She couldn't thank him enough for coming to her aid.
With everything done, the lady asked how much she owed him. Any amount would have been all right with her. She already imagined all the awful things that could have happened. Bryan never thought about being paid. This was helping someone in need. He had lived his whole life that way, and it never occurred to him to act any other way.
Byan told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person help the way he gave her, and he added, “And think of me to let the chain of love pass on.”
Hearing that she owed him nothing, with tears rolling down her cheeks, the old lady drove off with a deep “Thank you”.
A few miles down the road, the lady saw a small cafe. She went in to grab a bite to eat, and take the chill off before she made the last leg of her trip home. In the dirty- looking restaurant, the whole scene was unfamiliar to her; a waitress came over and brought a clean towel to wipe her wet hair. She had a sweet smile, one that even being on her feet for the whole day couldn’t erase. The lady noticed the waitress was nearly eight months pregnant, but she never let the strain and aches change her attitude. Then she remembered Bryan.
Paragraph 1:
After the lady finished her meal, she paid with a $100 bill.

Paragraph 2:
That night when she got home from work, she was thinking about the money and what the lady had written.
