1 . Life affects friendships. As we grow, marry, fight in wars, move across the country or change jobs, old friendships fall away and new ones form. As long as we live, the things around us change, and as long as things change, friendships are affected.
When we were children we had best friends. No matter what happened we were still friends. We live our lives, however, and do what life calls for us to do, and as we get older, memories fade (逐渐消失), faces blur (变得模糊不清), and even friends' names from childhood are forgotten.
Do you have a question about friendship? Do you wonder what to do with a friend who is no longer friendly? Perhaps you will see that you can't control others. If someone wants to be your friend, it is their choice. All you can do is treat them well and do the best for them when you are with them. Then you wish them well when they leave.
You can talk to old timers and they will tell you that life is full of incredible (难以置信的) joy and incredible sorrow, and that what bothers you today will one day become a memory and the sting (痛苦) will be gone. Seniors might tell you that you will learn more as you get older. They will tell you that friendships come and friendships go. Sometimes when they go it will hurt, but you will be okay with it. It's the way life works, after all.

2 . My first day of high school was like any other first day: registering, finding new classmates, meeting new teachers, and seeking new friends.
During lunch, I ran into my first snag (小困难) of the day. At the dining hall, as the checkout (付款处) lady asked for my money, I realized that I had forgotten my lunch money. When I told her about it, I heard a voice behind me. I turned around and there stood a teacher telling he would pay for my lunch. He told me his name, Mr. Peter Walker, and said, “If you get a chance, you should take my history class.” I recognized his name, and told him I was in his class later that day. Mr. Walker made friends with me on the very first day of school at a very crucial time of the day —lunch!
He always told us we should do more than we ever thought. He pushed us to do all things better. He coached many sports, and sponsored many after-class activities. If we were interested in something, he would find a way to expose us to it by inviting speakers, taking us on field trips, or obtaining information for us.
Two years later, my junior year in school was clicking along nicely when one day I was riding my motorcycle and I was hit by a car. I spent six days in hospital and was at home in bed for two weeks before returning to school. Mr. Walker stopped by the hospital each day with my work from my teachers. Once I was at home, he would bring my work too.
After high school, I attended the United States Army Airborne School in Fort Benning, Georgia. I knew my parents would be there the day I graduated, but they brought an unexpected guest. They came across Mr. Walker at lunch several days before and told him I was about to graduate. His visit, however, was not a surprise to me.

I used to have a really good group of friends. Now they're all getting into smoking and drinking. I want to find a new group of friends, but I'm shy. How can I know who are the types of people I should make friends with, and who will accept me?
Yours,
Mike
Dear Mike,
You've already made a very important step because you've realized that it's time to find new friends. Making and keeping good friends is a challenge for all of us, whether you are shy or not. Since you've done this successfully before, one thing is to think back on how you developed friendships in the past.
Probably the best way to make and keep friends is to find others who share your interests. Lasting friendships often develop between people who enjoy the same activities. You also want to be with friends who share your values and goals for life. It just depends on what your own interests are.
That old saying is also true — the best way to have a friend is to be a friend. Reach out to the others who share your interests, sit with them at lunch, invite them to join you in the activities you all like, listen to their thoughts and tell them yours. Being a real friend takes time and effort. With time and effort, I'm sure you will find some very good friends during your school years and you'll always be in touch after leaving school.
Yours,
Tom Black

4 . Do you like running enough to make it a habit? Tierney Wolfgram does; she has made running a lifelong career and isn't stopping.
In February, the 16-year-old from a high school, US, competed at the 2020 US Olympic Trials. She finished the marathon(42.195 km)with a time of 2:42:47 as the youngest competitor in the race and ranked 76th out of 390 runners. However, the cross-country(越野的)season was postponed to winter because of the COVID-19. So she jumped at the opportunity to train for another race-the Parkway Marathon in California. In November, Wolfgram broke the Women's American Junior marathon record with her time of 2:31:49. The old record was 2:34:32, which had stood since 1984.
“I'm completely stunned, ”said Wolfgram's coach. “I knew she was going to break it, but she really showed out！”
During the run, Wolfgram once hit a wall pretty hard, but she overcame it to finish. “I guess I can say I gave it my all, ”she told Runner's World. “When I finished, all I was thinking was I felt super happy,” Wolfgram said This was only her third marathon. In 2018, when Wolfgram was 15 years old, she ran her first marathon just because she wanted to see if she had the ability to do it. “I believed that I would get faster as the distances got longer. . . I'm still glad that I did it. ”
When preparing for that first marathon, she ran up to 120 miles per week. Although her parents didn't have any background in running, they helped Wolfgram train. At first, her dad would take her out in the morning and run about 13 miles. The distance would gradually increase each day. On top of her runs in the morning, she would do cross-country practice after school.
Now Wolfgram will consider attending the Olympics Games in 2024 after it's scheduled.

5 . We are surrounded every day by thousands of chemicals. These chemicals have been found to be safe－on their own. But are they still “safe” if mixed with other chemicals? That's the big question.
On its own, each chemical seems harmless. But in combination with other chemicals, they may become deadly. That is the finding of a two－year study by a high－profile task force of scientists. The task force was told to investigate the cancer－causing possibility of chemical mixtures.
Linda Gulliver was one of 174 scientists on the task force. Their job was to study the cancer－causing potential of 85 chemicals. All 85 are said to be common in the environment.
Ms Gulliver explains that chemicals have the potential to form dangerous mixtures. Even simple minerals can become dangerous when mixed with chemicals found in plastics or beauty products. While the chemicals are safe on their own. She says, the researchers found that many chemical compound cause cancer in human cells.
Working in groups, the scientists explored how different chemical mixtures could lead to cancer. Ms Gulliver's team looked at the ability of different combinations to support the increase of malignant (恶性的) human cells.
She says the big issue－what she calls “the $ 64 million dollar question”－is, “Which common, everyday chemicals do people need to avoid？”
“The $ 64 million dollar question that everybody wants to ask is, ‘Which chemicals should we be looking out for？’ And the answer to that is, ‘We don't know yet.’”
She says the current way to identify whether chemicals cause cancer is to test them one at a time. This method leads, she adds, to a long list of supposedly “safe” chemicals. She and her team say that approach needs to change.
“We definitely need certain research ... to find out what mixtures of chemicals would be more harmful than others; what groups of chemicals, when together, would produce more harmful effects. And at the moment, that is not known.”
1. The purpose of the researchers' work is ________.| A．to find ways to protect human cells |
| B．to study the character of the chemicals |
| C．to study how deadly the chemicals in our homes are |
| D．to study the cancer－causing possibility of mixtures |
| A．practical to other researchers | B．completely successful |
| C．still limited | D．not well received |
| A．Chemicals are everywhere |
| B．Chemicals can lead to cancer |
| C．What is in chemicals in our daily life? |
| D．Mixture of safe chemicals may cause cancer |
| A．Harmful chemicals are throughout our homes. |
| B．It is hard to tell what mixture of chemicals is harmful. |
| C．Researchers have quick approaches to studying the chemicals. |
| D．Scientists know which mixture does harm to our health. |
6 . It was 1504, and Columbus was making another trip to the New World. Columbus and his men needed fresh water and food after three months at sea. They saw an island and went to the shore. On the island there were unfriendly Indians who refused to give food and water to them. Columbus’ men were afraid of the Indians, but he had a clever plan. He used gesture language to tell the Indians about his mysterious power to turn off the light in the sky. He knew about a lunar eclipse (月食) the next night because the information was in his almanac. Columbus told the Indians, “Tomorrow night I’ll turn off the light in the sky.” But they didn’t believe him. When the eclipse began the next night, the Indians became very frightened. They begged Columbus to turn on the light again, and they quickly gave him all the food and water he wanted. Immediately Columbus and his men hurried back to the ship and sailed away in the moonless night.

7 . Everybody hates rats. But in the earthquake capitals of the world-Japan, Los Angeles, Turkey-rats will soon be man's new best friends.
What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First，the rat is trained to smell people. When this happens, the rat's brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University-New York says, “Robots' noses don't work well when there are other smells around. Rats are good at that.” Rats can also see in the dark.They are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn't get to and a rat would get out if it wasn't safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

8 . Did you know that the color of uniforms can influence the performance of an athlete? It may sound strange, but a study suggests this might be true.
Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform. They discovered that when there was a big difference in the score, color had no influence on the result. But if it was a close match, the athlete in a red uniform was more likely to win. Then they looked at the uniforms of the soccer teams at the Euro 2004 tournament (锦标赛). Again, teams wearing red won more games.
The two scientists got their idea from earlier studies of wild animals. It had been discovered that when a male shows red on its body, it sends a signal of its power and strength. For example, in many kinds of monkey, the more the male shows off its red scars (伤疤) , the more females it can attract.
Based on this fact, the British scientists thought that the idea might work for humans, too. According to them, when an athlete sees a competitor in a red uniform, he gets a feeling that he couldn’t be stronger than his competitor. And that kind of feeling may have a bad influence on the player’s performance in the actual game.
Although the idea is interesting, most people don’t accept that color signals in the animal world can really be useful to humans in sports. They think that it is unreasonable to develop an idea based on such a small number of examples. Much more research has to be done to prove the influence of uniform colors on the performance of athletes.

9 . Passenger pigeons were the most common birds in all of North America in the 1800s. It was common to see large groups of passenger pigeons — group that made a sound like a storm.
But today, they are extinct because of human behavior. Now, some scientists want to bring passenger pigeons back to life by using new technology and scientific ideas. They call this process de-extinction
De-extinction has not happened yet. It is still just an idea. The process of de-extinction is not easy. First, scientists must collect DNA from the bodies of extinct animals. Then they will put it in the eggs of similar animals species. When these animals become adults, they will have babies. And these baby animals will have the DNA of the extinct animals.
Scientists believe it is possible to bring back passenger pigeons and many other animals. However, not everyone think this is a good idea.
Stewart Primm is the world’s leading expert on modern animal extinction. He believes that bringing extinct animals back to life is bad for the earth. On the one hand, these animals no longer have a safe place to live. On the other hand, they could cause other animals to die.
Many other scientists do not agree with Stewart Primm. Stuart Brand, a writer and scientist, is one of them. He believes de-extinction is good for many reasons.
“The current generation of children will experience the return of some unusual animals in their lifetime. It may be part of what defines their generation and their attitude to the natural world. They will take their parents to zoos to see the growing populations of passenger pigeons, and maybe even dodo birds. This will provide a good deal of money for zoos busy with extinct species restoration (恢复). Humans killed off a lot of species over the last 10,000 years. So, it’s right to bring some back to life,” he said.

10 . A thief returned a mobile phone and thousands of yuan he had stolen from a woman after receiving twenty-one text messages from her, a local newspaper reported.
Pan Aiying, a Chinese teacher at Wutou Middle School in Qihe County, in East China’s Shandong Province, didn’t think her text messages would help to get her belongings back.
A young man riding a motorcycle robbed her of her bag, in which there was her mobile phone, bank cards and 4,900 yuan, as she was riding her bicycle home on Saturday evening.
Pan said at first she considered calling the police, but then decided to try to persuade the young man to return her bag. Pan called her lost phone with her friend’s, but couldn’t get through. So she began sending messages.
“Hey, I’m Pan Aiying, a teacher from Wutou Middle School. You must be going through a difficult time. If so, I will not blame you.” Wrote Pan in the first text message, which got no answer. “Keep the 4,900 yuan if you really need it, but please return the other things to me. You are still young. To make mistakes is human. Correcting your mistake is more important than anything,” Pan wrote in another message.
She gave up hope after sending twenty-one text messages without any answer and planned to call the police the next morning. However, as she left her home on Sunday morning, Pan found her stolen bag lying in the courtyard. Nothing was lost.
“Dear Pan: I am sorry. I made a mistake. Please forgive me. You are so kind even though I stole from you. I’ll correct my ways and be an honest man,” said a letter left with the bag.
