【推荐1】Where does your food come from? How is it made? These days, many people worry about food safety, but food safety is not a new worry. In 1906, Upton Sinclair wrote The Jungle. The book is the story of a poor family in Chicago. It is also about the dangerous ways that food was prepared. People were so worried that the U. S. started testing food.
These days, most food in the world is safe. Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But it’s more important to make sure the rules are followed. A good food safety system keeps people safe. It also helps them eat healthy food. Labels（标签） on food give people important information. Then they can make good choices about their food.
Although food safety systems usually work, there can be problems. Sometimes mistakes are made. For example, a truck might carry eggs and then ice cream. The ice cream could make people sick when the truck isn’t cleaned before carrying it. Other problems are not mistakes. Sometimes companies break rules to make more money. When this happens, people don’t know if their food is safe.
As we all know, food is closely related to our daily life. We should take action to make food safer!

Many scientists find that colors can change people’s feelings. It’s very interesting.
Some colors can make people feel relaxed, and some colors can make people feel nervous. Now, this kind of knowledge is being used in many places.

【推荐3】Today, with most of us owning a smartphone that lets us post on social media (媒体) wherever and whenever we want, oversharing has become harder to avoid. But the fact is that most of people usually don’t realize when they’re oversharing. We can get more facts from the following charts that were shown by a US survey.

Many Chinese people also like to post on social media, mainly including the photos of different food and the words of wisdom.
While sharing is indeed a good thing, oversharing, especially on social media platforms, is not good. For one thing, it may put people’s personal information at risk, because what they mean to share with only a small group of friends is actually broadcast to the whole world. Besides, oversharing online can influence people’s normal communication in real life, said Chen Canrui, a psychologist at South China Normal University. That is because oversharing makes deep communication less, which hurts strong social relationship, especially friendships. So it is very necessary for people to use social media properly.
1. According to Chart Ⅰ, how many U.S. adults think their friends overshare on social media?2. What percent of Americans post on social media once or more a day?

【推荐1】Have you ever taken PE classes with face masks(口罩), running, jumping, throwing? If so, that can be dangerous and risky.
When doing exercise or sports, breathing is faster and harder than at rest. It increases(增加) the risk of passing the disease on. As a result, people are considering having masks on, others may follow suit(跟着做), especially during the outbreak of COVID-19.
We know that exercise leads to faster and harder breaths, a mask makes it harder to take in enough air when you perform at the highest levels. At low to moderate-intensity(中低) exercise, effort will feel a bit harder than normal with a mask, but you still walk comfortably. The challenge appears to be more during heavy exercise, like rugby or football, taking in air at rates(率) of about 40-100 litres per minute.
When we do heavy exercise, our muscles(肌肉) produce lactic acid(乳酸), which causes the sense of burning. It is then turned into CO2 and stored. But what happens if the CO2 is stopped by the mask? As you move from moderate to heavy exercise, you may be re-breathing CO2. It can be bad for your health. There may also be less oxygen in the recycled air. It could be like exercising at highland. So it is important to understand the limits(限度) of heavy exercise with masks.

【推荐2】What picture do you have of the future? Will life in the future be better, worse or the same as now? What do you hope for about the future? Scientists think that life will probably be very different in 2050.
First of all, it seems that people won’t use TV channels by 2050. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television.
Water will become a very serious problem. We’ll need much more water, but there won’t be enough. Some scientists think that water would be the cause of war.
Cars will run on new clean energy and they will go very fast. And there won’t be any accidents with the help of computers. On the other hand, space planes will take people around the world in two hours.
Robots will work in factories instead of people. Many factories have already used robots. Big companies prefer robots—they do not ask for money, and they work for 24 hours a day.
In a word, by 2050, our life will change a lot and our future will be quite different from now.

The Great Wall of China is one of the greatest wonders of the world. The entire wall, which has many branches(分支), is about 8800 kilometers long. It runs from Shanhaiguan in the east (4) ①______ Jiayuguan in the west.
The construction was begun during the Warring States Period (战国时代), which was about 2500 years ago. The states of Qin, Wei, Zhao, Qi and Zhongshan all built walls to protect their people. The first emperor Qin Shihuang, joined all these smaller walls together to make the Great Wall.
These early walls that were made of earth and wood wore away in the rain and wind. Little of that wall remains. Most of the wall that can be seen today was built during the Ming Dynasty (明朝). (5) It was made of stone and brick (砖) that would last longer.

Trees are everywhere around us. They provide us with many useful things.
Before trees become helpful, they change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large deep green leaves so that they can catch enough sunlight and change it into their food and energy. When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit.
It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. Not only does the adult tree give us natural beauty, but it also cleans up dirt and fights flood. If we give the adult tree proper care, it will continue to live healthily for many years.
| Trees grow in many different places, so they have developed special ways to help themselves live. ●In deserts, trees need to hold on to water. The tree saves water in its trunk. ●In the highlands, trees grow very close to protect them from the strong winds. ●In the rainforests, trees grow up to fifty meters tall to get more sunlight. |
Gradually trees begin to grow older and older and even die. At this time they still have their important place in nature. When a tree becomes hollow (空心的) or part of it becomes dead, it provides a home for small animals.
In many ways, the life of a tree is similar to our own life experience. When we are looking at the life of a tree, we learn that each period of life brings its own form of joy and challenge.
Enjoy every minute of our life and take care of the trees!

The world’s population is still going up and scientists are worried that there will not be enough food for everybody in the middle of this century. One plant from Madagascar, the kalanchoe fedtschenkok, may help. The special plant takes in carbon dioxide（二氧化碳）at night and it needs 10 times less water than corn and similar plants. This means it can grow in the desert（沙漠）.
It is dangerous to eat this plant, but scientists can study two things: How it takes in carbon dioxide at night when other plants only do this during the day and why it can live in the desert. There will be less land for growing food in the future. Deserts are growing as Earth’s climate（气候）gets warmer. Growing food in the desert will be more and more important.
There are two possible directions for future research. Growing a desert plant to eat will be difficult, but it isn’t impossible. One way is to use the genes（基因）from this plant and put them into plant we eat, like beans or corns.
The other possible direction is to grow this type of plant for fuel（燃料）. At the moment, people are asking why good land is used to grow plants for fuel and not for food. If we use desert land, we can save the good land for food.
The world’s climate is changing and the population is still increasing. There may be not enough food for human. The special plant could be an answer to our future food need.

【推荐3】My husband and I bought a house when we were in our fifties. One of the reasons we bought it was that it was so attractive. It had a big Japanese red pine, which looked beautiful in our front yard. For 20 years, it was a beauty to all who passed by. Raccoons (浣熊）climbed its truck（树干）and squirrels played in its branches. It shaded the bright sun over my small garden of roses and bushes（灌木丛）that I’d planted for bees.
Early last year, a heavy snowfall hit our city. While we were enjoying a quiet Saturday morning, the house shook and we heard a loud crash（撞击声). The tree had fallen, taking out most of the bushes in our yard. So we called forestry workers, who cut off its truck and branches and took the wood away. After a week, the yard was still a mess, with wood shavings (木屑) and holes everywhere.
In March, I bought a few new bush and rose seedlings to replace those that I thought hadn’t lived. But in May, plenty of new flowers were growing in the yard! As the sun shone down, the flowers were able to grow and attract bees. My old bushes grew back and were healthier than ever before! Our yard turned into a beautiful garden. And this summer, one year later, all of the plants are three times bigger than they were before.
Life might be hard for you at the moment, but you never know what the future holds. It might just be much brighter.
