1 . ①Have you ever noticed that fruits and vegetables are still fresh after a long journey? Using the right vehicle (交通工具) for transporting helps keep the quality of the fruits and vegetables. Reefers can be one of the great helpers.
②Reefers are trucks that work like a large fridge. They have a special system that is designed to help keep products fresh. The system keeps certain temperatures and controls humidity (湿度). At the same time, it lets in fresh air and lets out gases like CO2. The system has several parts.
·Control unit: Change the temperature, humidity and airing of the reefer container (集装箱).·Interior fans: Help the air move around inside the container.
·Fresh air vent: Gases can escape through the air vent, and fresh air can flow (流动) inside the container.
·Unit evaporator: Keep the humidity at the right level inside.
·Condenser: Cool the air in the container and move it around.
These parts make reefers a good choice for transporting fruits and vegetables.
③ The reefer temperature for fruits and vegetables is one of the most important factors. It can affect their quality. But reefers only maintain the temperatures of products, not change them. You should make sure products are already at the correct temperature before loading them into the reefer container. The reefer temperature for vegetables should range between -1℃ to 13℃. Here are a few examples: carrots: 0℃; cucumbers: 10℃ to 13℃. For fruits, the proper temperature is from -1℃ to 4℃, like apples: -1℃ to 4℃; grapes: -0. 5℃ to 0℃. The reefer temperature for fruits and vegetables should be proper to provide high-quality products for markets and stores.
④ When using reefers to transport fruits and vegetables, you should know how to pack them correctly. Use boxes that allow for air to move around. Cardboard boxes and plastic bins with holes are OK. Avoid putting boxes too close to the walls of the container, or the air won’t be able to flow smoothly. Separate certain fruits and vegetables from those giving out a gas which makes them ripen faster.

Julie Andersen’s great interest in diving (潜水) led to her love for sharks and the ocean. She turned her love into a job and started ocean conservation groups. Conservation is the act of keeping or protecting something. Conservation work includes protecting art, animals in danger and the other parts of the natural environment.
Andersen began diving in 1995. She started diving in places that are famous for sharks. Unluckily, the number of sharks there became smaller and smaller. Soon she realized that she must do something for them. So she founded the Shark Angels and helped people around the world learn about sharks. She even sold her house to support Shark Angels.
Twenty years later, she is still working. As a leader of Professional Association of Diving Instructors(PADI), Andersen believes PADI is a good industry to encourage people to keep on saving sharks and their ocean homes. She often says, “I am filled with hope. The past several years have taught me that a single person can make a difference. And I am sure we can make a bigger difference together.” Andersen sets a good example to other people in the world. Now more and more people are entering the diving industry and getting to know the importance of protecting sharks and their ocean homes.
Actually, Andersen’s goal is to make it possible for everyone to experience, fall in love with and, in turn, protect our world’s largest and most valuable ecosystem (生态系统). “The ocean gives us life. We need to do the same in return and leave our blue planet better than we found it.” Andersen says.

6 . In a high mountain area in central Utah stands the world’s oldest, heaviest and largest tree, Pando. And it’s dying!
Pando means “I spread” in Latin and it’s a name that makes sense. Pando is a big group of trees that all grow from the same roots (根). They look separate but are all connected underground by their roots. With all these roots connected, the whole group of trees can share water and food.
Protecting Pando is challenging. Putting fences (栅栏) around it to keep animals away has helped new growth. But deer are smart, and they’ve found ways to get through the fences. Other efforts have included cutting or burning part of Pando to encourage new growth. Pando grows back very quickly after a forest fire, and these fires do not reach temperatures that would kill its root system.
Michael Grant, one of the scientists who helped name Pando, warns if the trees are in trouble, the whole ecosystem will be in danger too. We need to make people understand the long-term effects of our actions.
1. Which picture is Pando?A. | B. | C. | D. |

①“Why don’t you ever listen?”
“You just don’t understand me!”
“You’re of no help at all!”
②Sound familiar? When you’re having a difficult conversation with your parents or friends, accusatory words like those can stop a discussion. As soon as one feels attacked, the defensive (防御的) walls come up, and real communication becomes all but impossible. We focus on the other person’s behavior first, without spending time thinking about and telling why we’re feeling hurt. Here lie the differences between “I” and “you” statements.
③An “I-statement” is a sentence beginning with the word “I” that tells another person how you are feeling in a clear way. For example, you might say, “I feel...” or “I become nervous when....” I-statements are a powerful tool to help you express your feelings to someone else without blaming (责怪) others. “You-statements,” such as those listed above, are statements that begin with the word “you”, pointing out what other people have done wrong. These statements often mean that the listener is responsible for something.
④Why are I-statements important? When you start a conversation by talking about the other person’s actions, you’re sending the message that they’re the problem. For most people, this immediately leads to them becoming defensive and trying to throw blame back onto you. However, starting a sentence with ‘I’ helps us talk about difficult feelings and how the problem is affecting us, and stops other people feeling blamed. This can be seen in the case when you feel left out. Instead of saying “You always leave me out”, you can say “I feel hurt when I’m not invited because it feels like I’m not welcome”. With this I-statement, you’re being honest about your feelings, but you’re not presenting them as something the other person did to you. As a result, the listener tends to experience this as more friendly, opening the possibility of further conversation and hope for a solution.
⑤It’s a simple change, but by being a little more careful of how you express yourself, you may find people are more likely to positively listen to you and understand more about what you are trying to say.
1. What does the underlined phrase “accusatory words” mean?A.Words that attack others. | B.Words to explain reasons. |
C.Words that sound familiar. | D.Words to start conversations. |
A.I know that everyone in the family is busy. |
B.I am anxious when everything is in a mess. |
C.I think you are right by telling me the truth. |
D.I feel sad because you don’t listen to me carefully. |
A.By using sayings. | B.By asking questions. |
C.By telling a story. | D.By giving an example. |
A.To encourage people to use I-statements. |
B.To explain when I-statements should be used. |
C.To show the disadvantages of you-statements. |
D.To suggest being careful of others’ you-statements. |
8 . When nature meets man-made roads, it’s seldom a good thing. Millions of animals get killed by cars every week. So, engineers tried to build green bridges for animals over busy roads. These bridges help keep animals and people safe.
The idea of green bridges isn’t really new. In fact, the first animal crossing appeared in France in the 1950s. As well as Germany, which has made more than 80 green bridges since 2005, Canada and the United States are also trying to protect native wildlife by building animal bridges over the years.
Although there are various designs, most green bridges share something similar. First, they are usually quite wide, giving animals plenty of room to move. Second, they are usually covered with soil and plants to look like the forests that lie on either side of the roads. Lastly, they are wider at the ends, spreading out where they meet the land. This helps gather animals onto the bridge and guide them out when they leave.
People may wonder ________. In Canada’s Banff National Park, 11 kinds of large animals such as bears, elk and cougar s have already gone across these green bridges more than 200,000 times since 1996. In some places, we’ve also seen a 90% drop in accidents between animals and cars where these bridges have been built.
These crossings are clearly a step in the right way to offer living chances and safety to wild animals. And with these bridges, both animal and human deaths on roads will continue to go down.
1. Where was the first green bridge built?A.In America. | B.In Canada. | C.In France. | D.In Germany. |
A. | B. | C. | D. |
A.if these green bridges really work |
B.if Canada built the best green bridges |
C.if it is easy to walk across green bridges |
D.if there will be new designs for green bridges |
A.Green Bridges: Helpful Ways to Save Plants |
B.Green Bridges: A New Home for Wild Animals |
C.Green Bridges: Safe Crossings to Protect Wildlife |

9 . Imagine a city built as a line across the desert. It can run on 100% clean energy and 100% renewable water. That sounds impossible, but it’s becoming a reality.
Saudi Arabia is building such a city called The Line. It starts from the mountains of Northwest Saudi Arabia and pushes its way to the Red Sea. With an area of just 34 square kilometres, it can be home to 9 million people. The Line is 500 metres tall, 200 metres wide and 170 kilometres long, with two huge mirror walls standing on its both sides.
To put living experiences and natural environment first, The Line is designed to have three layers (层) . The top layer has no roads or cars, keeping over 95% of the nature around. Carefully designed environment makes the best balance of sunshine, trees and other natural sights. The middle layer is for services. All of them are operated by AI. Robots and a huge man-made moon make the city a technology paradise (天堂). From shopping malls to sports areas, wherever you go, you will be amazed at how convenient life can be. The lowest layer is the most important pat which shows how fast the city runs. The Line’s high-speed railway powered by electricity makes it possible to travel end to end in 20 minutes.
The plan started in early 2021 and is expected to finish its first stage in 2030. However, not everyone shows enough confidence in the plan. Environmentalists argue that mirror walls of The Line will bring danger to animals. For example, birds may hit onto the glass or even die when they migrate every spring and autumn. Besides, some commentators (评论员) also question whether the city will be built successfully. But Tarek Qaddumi, the director of the plan, seems sure, “We hope to get faster, better and greener results, with less environmental influence. It will set a new standard for future city life.”
