Many of us stayed at home in January because of COVID-19, but a special mom and her two babies took a trip. They were driven a few miles from a breeding center in northeastern Argentina to a 1.7 million-acre nature reserve called Gran Ibera Park. There the three jaguars were released into the wild.
Their release was the first reintroduction of jaguars in that part of Argentina since the species ( 物种 ) almost died out there 70 years ago. Scientists hope they can turn things around for this important apex predator, meaning one that is on top of the food chain ( 链 ). Only 200 to 300 jaguars remain in the country.
“That is the highest level of protection that can be given in Argentina,” says Sebastian Di Martino. He’s the conservation director for Rewilding Argentina, which is one of the organizations helping to restore jaguar populations.
The jaguars’ journey started in 2018 when the park was built in the Ibera Wetlands. Several thousand jaguars once lived there, along with other important species. But the jaguars’ fur was valuable, so people hunted them. Then farmers cleared the land they lived on. With the jaguars gone, the ecosystem was out of balance.
“In the absence of this species, ecosystems stop working well and may even collapse,” Di Martino says. “The main prey ( 猎物 ) of the jaguar is the capybara and the caiman. They are very abundant because of the absence of the jaguar, which causes imbalances in the ecosystem.”
The park was the first step to give jaguars a place to live. Then they needed to breed. A female named Mariua mated with a male jaguar from Brazil. Mariua then gave birth to the two baby jaguars.
It sounds simple, but the reality is more complicated. Di Martino said that jaguars born at breeding centers have to learn how to hunt and must not become used to humans. Otherwise, they will not have success in the wild.
The people who work at the breeding center stay out of sight. They use video cameras to watch the jaguars from several miles away. “We provide live prey for them, without them realizing it comes from people,” Di Martino said.
Mariua wears a radio collar so researchers can track her and her babies, Karai and Pord. “So far, so good. She’s been hunting capybaras and wild pigs and is raising her babies very well,” Di Martino says.
1 . What can we learn about the jaguar?
A . It is found only in Argentina. B . It is taught to hunt by humans.
C . It is not hunted by any other animal. D . It is not considered as a rare species.
2 . Which of the following words can best describe Di Martino’s job?

A . to give an example of jaguars’ life B . to show the importance of female jaguars
C . to introduce a way of training jaguars D . to explain the method of rewilding jaguars

It was a cold and snowy morning after the winter vacation. Actually, it was my first day at my new school. I was walking slowly and worrying about lots of things. It was 7:00 in the morning and there weren’t many people on the road. A girl on a bike passed me quickly. She was riding on ice when suddenly she fell off her bike a few steps in front of me. She was trying hard to get up but fell once more. Without thinking, I went over and helped her stand up. She said, “Thank you,” with a smile and then rode away. The words “Thank you” warmed me and this small event made me feel less nervous about my new school.
Finally, I got to school. The teacher led me to the classroom and asked me to sit down beside a girl. I was so nervous. I knew some of the students were looking at me but I didn’t dare to look at them. Soon the first class started. It was English. They used a different textbook from my old school and I didn’t have a copy. As I was wondering what to do, a book appeared in front of me. “Let’s share,” the girl next to me said. “And hi, I’m Carrie.” I looked up. It was the girl I helped that morning. What a surprise!

There is a famous English saying “You are what you eat”, and it means what you put in your mouth will become part of you. Many experts ( 专家 ) use it to tell people it’s important to have a good eating habit. For example, too much sweet food makes a person overweight. To avoid being fat, kids are told to keep off sweet food. However, a team of American scientists have discovered something new about eating sweet food.
“When we say some people ‘sweet’, we mean they are kind and friendly to us. Perhaps this word can help us learn more about people’s feelings and acts,” said Brian Meier, a scientist from the study team. “Taste is something we experience every day. What we have done is to find whether we can know someone’s character and behavior depending on their taste.”
In one of their experiments, college students were asked questions about their character — whether, for example, they were soft-hearted or not. Then they were asked to make a list of their favorite food. According to their answers, the scientists found that the students who liked sweet food were nicer.
In their another experiment, the scientists found that people who preferred sweet food such as cookies and chocolate were more willing to help other people in need, and those who ate non-sweet food such as chips weren’t. For example, people with a sweet tooth were more likely to volunteer to clean up their city, visit sick children in the hospital and so on.
The result of the experiments is that people’s helpfulness or being nice has something to do with their taste for sweet food. So eating sweet food is a useful way to make people nice and helpful. Next time, try some ice-cream.
1 . According to the result of the experiments, sweet food can make people ________.
A . overweight B . excited C . relaxed D . friendly
2 . The purpose of the experiment in Paragraph 4 is to show ________.
A . character and behavior has something to do with people’s taste
B . why some people like sweet food better than other kinds
C . people who like cookies and chocolate like helping others
D . non-sweet food eaters are not willing to volunteer to help those in need
3 . We can learn from the passage that ________.
A . people’s taste decides their characters and acts
B . sweet food makes people overweight
C . people with a sweet tooth are more willing to help others
D . people’s character has nothing to do with their taste

Walking
If you want to get healthy or stay healthy, there is one easy activity for you — walking. You may think that simply taking a walk is not enough to make a big difference. You may think that you need to do something like running to stay healthy. Well, a new study says that is not true. It finds out that walking may be as good for us as running.
Running is a high-impact ( 高强度的 ) activity and can be hard on the body. So, many people cannot run. Walking seems to have all of the advantages and none of the disadvantages of running.
Dr Russell Pate is a professor of exercise science at the Arnold School of Public Health at the University of South Carolina. He says, “Walking is one of the easiest and safest exercises a person can do. You do not need to learn a lot to get results.”
Walking needs no special skills or equipment . You can do it anywhere. It fits easily into your daily schedule ( 日程表 ). You can walk at work. You can walk if you want to go shopping. You can take the stairs instead of the lift.
Walking is a great exercise for beginners. If you are out of shape or getting back into shape after an illness or accident, walking is perfect. You can do a little at a time, or as we like to say, take baby steps.
