1 . Today, people travel around the world by air and enjoy the great convenience it brings, but studies show that air travel is bad for the environment. It’s responsible for about three percent of the world’s greenhouse gas emissions (排放物). Then do we have to give up flying to save the planet? Maybe not.
Last month, a British airline (航空公司) operated a flight (航班) called Flight 100. It flew from London to New York with some reporters, engineers and government officers on it. There were no paying passengers. The flight was special because the plane used waste fats and plant sugars as fuel (燃料). As a new kind of green fuel, it was different from the traditional fuel and it cut the flight’s pollution by 70 percent according to the company. Some people said that the flight meant a lot. Many more people wanted to have a try on the flight.
However, there are still problems. For one thing, the green fuel costs five times as much as the traditional fuel. For another, it is difficult to make enough green fuel for all the flights around the world in a short time. To provide enough fuel for a large number of planes, farmers will have to grow more plants. Therefore, more forests will be cut down for farmland.
For now, the British airline and other airlines have no plan to provide similar flights for the public. There is still a long way to go before air travel becomes greener. But one day in the future, such flights may become common and the greenhouse gas emissions may be reduced.

2 . Most people are afraid of sharks, but they usually do not know very much about them. For example, there are 350 types of sharks and all of them are meat eaters. Some sharks are very big. The whale shark is 50 to 60 feet long. But some sharks are very small. The dwarf (侏儒) shark is only 6 inches (英寸) long.
Sharks are 100 million years old. In fact, they lived at the same time as dinosaurs. Today sharks live in every ocean on the earth, but most sharks live in warm water. They keep the oceans clean because they eat sick fish and animals.
Most sharks have four to six rows of teeth. When a shark’s tooth falls out, another tooth moves in from behind. Sharks do not have ears. However, they “hear” sounds and movements in the water. Any sound or movement makes the water vibrate. This helps sharks find food. Sharks use their large eyes to find food, too. Most sharks see best in low light. They often hunt for food at dawn (黄昏), in the evening or in the middle of the night.
Scientists want to learn more about sharks for several reasons. For example, cancer is common in many animals, including people. However, it is rare (罕见的) in sharks.. Scientists want to find out why sharks almost never get cancer. Maybe this information can help people prevent cancer too.

3 . International Volunteer Day is on December 5 every year. It started on December 17, 1985. It’s a day to honor volunteers all over the world.
Every day and every minute, volunteers around the world work out of their own kindness and make the world a better place. They protect the environment, build schools, care for animals. Most volunteers work without getting paid, and many do so using their own money. International Volunteer Day offers us a chance to do so.
Celebrating International Volunteer Day also lets more people know about the work and encourages them to join the volunteer team. When people see how volunteering is changing things for the better, they may want to donate (拼赠) their time and play their part.
Doing volunteer work is also meaningful.Volunteering is a good way to open our eyes. We may do something we never do and meet different kinds of people. We can talk with them and get their good ideas. Volunteers especially students can learn much from practice, get some experience and know how to solve problems.
There are many problems in the world. No one has answers to all the problems. But when we face them together, we’re able to find good ways to solve them. The things we care about today will help build a better world tomorrow.

4 . Do you know that the falcon (猎鹰) is among the fastest animals in the world? It can fly at a speed of about 200 miles per hour. You might think a bird that could fly so fast would be safe from most type s of danger. But that is not true. By the 1970s, they had already been endangered. Luckily, people begin to protect them. The number of falcons is rising now.
One unusual thing about falcons is that they like to make their nests (巢) in high places. In nature, they often nest on mountain tops and on the sides of cliffs (悬崖). Falcons have also got used to life in cities. They nest on tall buildings and bridges in cities. The height of these nests is from 50 to 200 feet in the air.
They also like to return to the same nesting place every year. Both the mother and father falcons help to raise the babies. The mother stays more time in the nest. The father hunts and brings back food for her and the babies.
Many people all around the country work very hard to help falcons live to adulthood. There are even video cameras fixed up in many places. This way, people can make sure the birds and their eggs stay protected. Falcons are lucky to have so many people who keep an eye on them.

5 . What will travel be like in 2070? Maybe travel will become smarter and easier by that time. Here are some amazing predictions about traveling that might happen in 2070.
You will use “heart be at passport” at the airport. And passport checks will not be used anymore. Because everyone’s heartbeat is different and it can tell you who you are and where you will go. Also, it provides more personal information.
3D print technology will develop surprisingly fast. It can print almost everything like clothes and food. Therefore, when you get to the hotel, suitcase will not be needed any more.
The trip will become interesting and colorful. Many kinds of services will be provided during the trip. If you want to see what happened in the Ming Dynasty or the first Olympic Games, you can just wear a special headset or glasses.

6 . Recently, a research on how a new virtual reality (VR虚拟现实) experience educated children about the fire disasters was done. The new VR experience was developed by the University of South Australia, hoping to educate children to learn how to be safe in a fire. It presents a situation for children aged 10-12. In the situation, they are tasked to look after a friend’s dog just before a fire event begins. They take part in a set of problem-solving activities to help save and protect themselves and the dog.
The findings showed that over 80% of children could calmly tell the advantages and disadvantages of different choices. They also learned to make wise decisions to protect themselves from a fire. Children thought it especially important and meaningful, because 91% of them didn’t have knowledge of fires at the beginning, and 67% had said that they were too young to make safety decisions in a fire.
The researchers believed such VR experiences made it possible to engage (使参与), educate and empower the young. “As children born in modern times, they are interested in such technology and they can experience events in a real situation yet within the safe environment,” said Delene Weber, one of the researchers. “Well-designed VR can provide children with surprisingly valuable learning tools.” Meanwhile, because children have fewer life experiences, aren’t as physically strong, and are less likely to have learned much about fire safety, they’re often most at risk. However, the role that children play in the fire safety at their homes should not be underestimated (低估). “Children don’t need to be always waiting for help in disasters. With these VR experiences, we can make children understand the risks and realize they can help,” said Weber.
1. What’s the purpose of the new VR experience?| A．To describe children’s reactions to fire disasters. |
| B．To teach children to save themselves in a fire. |
| C．To introduce ways of avoiding a fire to children. |
| D．To increase children’s interest in VR experiences. |
| A．Doubtful. | B．Worried. | C．Uncertain. | D．Supportive. |
| A．development | B．advantages | C．quality | D．introduction |
| A．Well-designed VR can offer children amazingly valuable learning tools. |
| B．VR experiences are mainly designed for children in high school. |
| C．Children make no difference in the fire safety at their homes. |
| D．91% of children believed they weren’t old enough to make safety decisions. |
7 . I am sure you know the story of the turtle (乌龟) and the rabbit. It taught people many lessons. One of these lessons is that people who have all the advantages (the fast-jumping rabbit) can be beaten by those who have nothing but inner (内心的) strength (the slow turtle).
It is true that the race of life, just like the one between the rabbit and the turtle, is often unfair. Some kids have all the luck. They were born healthy and their parents are rich. These kids wear nice clothes and always have much money to spend on anything they like. Many other kids, however, have none of these things. Some of them were even born with disabilities. They have to depend on their inner strength alone.
While many people believe the “rabbits” are always successful, this is not true. In fact, the “turtles”—kids from poor families—have some of the most. important things for success. They are humble (谦逊的) and determined (有决心的). They march forward slowly but with great inner strength.
A student from Tsinghua University shared his personal experience online. Instead of having fun with his classmates outside, he chose to get a part-time job and study hard. He knew there would be plenty of time for fun once he had overcome all of the difficulties. His story may have encouraged “turtles”. The race of life is long. Even if you get off to a slow start, you can easily catch up if you make up your mind to do so.
1. What can we learn from the story of the turtle and the rabbit?| A．One who has advantages can succeed. |
| B．One who fears nothing can succeed easily. |
| C．One who has inner strength can get success finally. |
| D．One who works without rest can get success more easily. |
| A．Because everyone wants to win the race. | B．Because people are treated differently in life. |
| C．Because all the people have different dreams. | D．Because not everyone’s starting point is the same. |
| A．To introduce his hard experience to us. |
| B．To encourage us to enter good universities. |
| C．To show us the importance of studying in the university. |
| D．To support the idea that poor students have special things for success. |
| A．To advise us to try new things. | B．To tell us how to succeed quickly. |
| C．To show us the power of inner strength. | D． To encourage us to take races. |
8 . “On a spring night, we offer book lovers a desk and a light. You can stay here as long as you want to.” This is the slogan (宣传语) of Sanlian Taofen Bookstore in Beijing.
Earlier this month, Sanlian Taofen Bookstore became the first 24-hour bookstore in the city. It hopes to encourage more people to read books. Bookstores are the brain of a city. Although many people can now buy books online, many readers still like the feeling in bookstores. They can touch the books and smell the print.
In China, most cities are home to at least one bookstore. Some have special themes (主题). Popular Holdings (大众书局) in Shanghai is a film-themed bookstore. There are film books and posters (海报) inside. Other bookstores have colourful activities. Eslite Bookstore (诚品书店) in Taiwan has activities like talks with famous writers as well as holding gallery shows (画展). People come here not only for reading but also to communicate with others.
1. Which of the following can best describe people’s feeling in bookstores?| A．Becoming the brain of the city. | B．Staying inside as long as possible. |

9 . ChatGPT is back! OpenAI, the company behind the popular chatbot, has now introduced a powerful new language model: GPT-4.
On March 14, GPT-4 showed the world how smarter it is than the GPT-3.5. One of its best new features is that it can understand pictures. For example, if you show a picture of a phone using the wrong charger (充电器), GPT-4 can tell why the picture looks strange.
But GPT-4’s developments don’t stop there. The new language model can code (用代码编写) classic games in a few minutes, and produce the code and layout (布局) for a website based on a hand-made drawing. GPT-4 is much better than the older GPT at passing tests. According to CNN, GPT-4 did really well on a law school test, with a score in the top 10 percent of test takers. ButGPT-3.5 only got a score in the bottom 10 percent.
GPT-4 will also power other apps and services. For example, the language learning app Duolingo plans to use GPT-4 in their coming products. Users can learn languages by talking with AI. Another app, Be My Eyes, will have a digital assistant (数字助手) to help blind people better understand the world around them. The government of Iceland also plans to use GPT-4 to protect the Icelandic language.
There are still problems with the new language model, however. GPT-4 still tries hard to get completely correct answers. And it will sometimes insist that wrong information is true.
1. What does the underlined word “it” refer to?| A．OpenAI. | B．GPT-3.5. | C．GPT-4. | D．A chatbot. |
| A．Because GPT-4 is much new er than GPT-3.5. |

10 . Electric vehicles (电动汽车) or EVs recently have become more and more popular. Technological improvements, especially batteries, make EVs rather than gas cars become more people’s first choice.
Mueller, an expert in studying cars, explains why they are the future of cars. He writes, “I think EVs are the future. They have better torque (扭转力), acceleration (加速) and better control.”
Best of all, you never have to visit a gas station. Every morning your car is charged (充电) and ready to go. And if you are worried about miles they can cover, that’s not necessary. Almost all trips can be done in an EV with a proper battery. And fast chargers (充电器) along the way make it possible to do longer road trips if necessary.
Besides, it’s clean technology: a traditional gas car causes more than twice as carbon (碳) pollution as an EV. Even in places that get almost all of their electricity from burning coal (煤), an EV still pollutes less than a typical traditional gas car. Supposing a 10-year service life, a traditional car will let out 66,000 pounds more carbon pollution than an electric vehicle.
Human science technology is always moving forward. However, some challenges still remain about EVs. According to the present situation of EVs, scientists and researchers still have a long way to go.
1. EVs have become more popular than gas cars thanks to ________.| A．technological improvements | B．social development |
