You may always pay attention to hunger(饥饿). Hunger has many different causes, according to Dr. Monique Tello, from Harvard Medical School.
The first cause may be a medical problem. “If a person always feels hungry and can’t put on weight or even loses weight, he should go to the hospital. For people with Type I diabetes(糖尿病), their body isn’t able to process sugar. They eat a lot, but still lose weight and they feel terrible.” Tello said.
If it isn’t a medical cause, the problems could be in the head. It’s reasonable to be hungry every three to five hours. However, it’s possible for you to eat often and a lot after watching food advertisements on TV or social media(媒体). Also, the more you eat, the larger your stomach gets, and the more you want to eat. A person’s state(状态) of mind can play a role. too. Research has shown that stress can increase levels of hunger hormones(激素) Pressure and worry drive people to look for food in the fridge when they’re no truly hungry.
Another reason may be the lifestyle. Sometimes the reason why a person is always hungry is that he eats too little, exercises too much, or both.
So, how to solve the problem? There are three ways to solve it. First, reduce(减少) your time on watching food advertisements on TV and social media. In addition, say no to food if you’re not really hungry. Finally, change your diet by eating more food high in fiber(纤维), protein(蛋白质) and healthy fats.

The Difficult Search for American Products in the US
If you go to another country, what kind of things would you buy? Would you buy a camera in Japan, some beautiful clothes in France, or a watch in Switzerland? No matter what you may buy, you might probably think those products were made in those countries. However, you could be wrong. Kang Jian is a 17-year-old student from Shanghai. Last year he went to visit his aunt and uncle in San Francisco. He found it interesting that so many products in the local shops were made in China. “I wanted to buy a toy car for my cousin, but even though most of the toys had American brands, they were made in China.”
Toys are not the only things made in China. “I wanted to buy a pair of basketball shoes,” he explains, “but I had to visit five or six stores before finding a pair made in America!” He realized that Americans can hardly avoid buying products made in China. “In fact,” he continues, “there are so many things made in China—footballs, handbags, pet food, mobile phones. Even American flags are made in China!” Kang Jian thinks it’s great that China is so good at making these everyday things. However, he wishes that in the future China will also get better at making high-technology products that people can buy in all parts of the world.

3 . In the year 2070, most of you will be more than 60 years old. The good news is that travel might become smarter by that time. European airline(航空公司) easyJet has made some predictions and released(发布) easyJet 2070—The Future Travel Report. Let’s take a look at some cool ideas.
Heartbeat(心跳) passport
Paper passports will be a thing of the past. You will use “heartbeat passports” instead. According to experts, everyone’s heartbeat is different. So the data(数据) will be used to tell who you are.
More comfortable flight(飞行)
The seats on the plane will no longer be “one size fits all”. You’ll actually be able to book(预定) a seat according to your body type(型). The seat might even be able to cool or warm you to your preferred temperature. There will also be no more screens on the back of your seats. A future device(设备) could show movies straight in front of your eyes.
Printed clothes and food
If you hate packing clothes, you may not need to do it in the future. Before you fly, you will have a body scan(扫描). When you arrive, you’ll find a wardrobe(衣橱) filled with 3D-printed clothes in your size. When you leave, the clothes can be recycled and reprinted for the next person. You can also 3D print whatever you want to eat.
Bring history back to life
If you like to visit places of interest, augmented reality(增强现实) will change the game. Wearing a headset(头戴式耳机), you can see what happened there, such as a famous war.

All kinds of pollution and waste are doing harm to the earth. And small steps add up to make a big difference. There are lots of steps you and your family can take to help the planet. Here are a few ideas.
Save energy
First of all, turn off the unused lights in time and consider using energy-saving light bulbs(灯泡), which can save much electricity. Then use less water. For example, you can take shorter showers. Also, turning off the tap(水龙头) as you brush your teeth can save much water, too.
Choose green travel
If the place you want to go is not far away, please ride a bike instead of driving a car. Riding a bike seems to be a better choice. Because it can help cut down the air pollution. Otherwise you can choose public transportation, such as taking a bus or subway.
Say no to waste
The easiest step you should take is to avoid wasting food. Don’t take more than you can eat. Growing food needs much work. Moreover get long life out of things you own by taking good care of them. If something is broken, don’t just throw it away. You can try to fix it or use it to make something else.
Use reusable things
When you go shopping, don’t use a paper gift bag. Because it is not environmentally friendly. Disposable(一次性的) plastic and paper bags can pollute oceans and the soil. They are hard to break down. A reusable cloth bag will be a wise choice.

5 . How important is music? Many people usually think that listening to music is nice but not very important. It is often only thought to be entertainment（娱乐）but not that choice for education. Most parents think that it is not important to learn music. They think that their children only need to study hard at school. This opinion is wrong. In fact, music education is much more necessary than people usually think.
Music provides people a kind of ability to know the world in a different way. Music is so magical. It can express（表达）different emotions, such as sadness and happiness, anger and excitement. People need music to learn more about ourselves, our culture and our world.
Music shows people’s different thoughts. It is a special language we can talk to each other and exchange our thoughts in this amazing way. Through the language we express our feelings, ideas and hopes. When we do not let our children receive good music education, we may take them away from the meanings that music expresses. Our children lose a wonderful part in their lives possibly. So music education is necessary for our students.
Under the double reduction policy（双减政策）, students have more free time to learn to sing and play the piano or guitar after school. Learning a kind of musical instrument can make children learn happily and get happiness in learning. And it will also help students become better and more confident. Taking up an instrument also makes students’ life more colorful.
Some scientists think that music makes people think and learn better. Music helps students to be more active. It is true that people learn better when they are relaxed and listening to music.
Parents should give children spare time to improve their musical abilities and encourage their children to make their life colorful.

Nature is the most creative artist. Daocheng Yading（稻城亚丁） is such a place in which nature has put a lot of work. It is a magical and mysterious land in the southwest of Sichuan Province. It is well known as “the last pure land on the blue planet”.
Daocheng Yading is a kingdom（王国） of beauty and even the best painter can’t draw it well. Tall mountains stand in the snow, clear lakes shine in the sun, animals walk freely in the large pastures（牧场）, and trees sway（摇摆） in the wind in the forest. Everything is beautiful in its own way, and at the same time they build a wonderful picture together.
There are three famous snow mountains standing in Daocheng Yading, protecting the people around them. Yangmaiyong is the greatest one. It is about 6000 meters in height and has the shape of a perfect pyramid. Back in 1928 an American named Joseph Rock first took photos of it and introduced it to the world. “She is the most beautiful snow mountain my eyes have ever seen,” he wrote. Next to it, stand two other great mountains: Xiannairi and Xianuoduoji. For most visitors, they are beautiful beyond（超过） words.
The locals say that if one can walk around these great mountains three times, then his wishes for life will come true. It is a big challenge to do so, but many visitors like to give it a try. Why? They may tell you: Life naturally gets better when you walk on such a pure land!

8 . When we look at a picture of Earth from space, there are areas of green, blue, and white. Most people will recognize that the green is land, the blue is water, and the white is clouds. Taken as a whole, Earth is mainly blue. That is because of the amount of water it has that covers the surface.
So, how much of Earth is water? About 71% of Earth’s surface is covered in water. Of that 71%, the oceans hold 96.5% of the water. This water found in oceans is all salt water. The remaining 3.5% of the water is fresh water, which can be found in lakes, rivers, glaciers (冰川), and in the ground. Fresh water is what people use for farming, raising animals, drinking, and daily activities such as taking showers and washing clothes or dishes.
Does the amount of water stay the same? For the most part, yes. Water on Earth is part of a closed system. That is, water is always moving and changing forms between ice, liquid, and gas. The form of the water changes all the time, but the total amount of water on Earth remains the same.
If Earth is not necessarily running out of water, why are people worried? Why do we need to think about saving water? First, humans can only use fresh water, which is only 3.5% of all of Earth’s water. Second, of this 3.5%, only 1% is available for human use. Most fresh water is found in glaciers far from where anyone lives. Third, the amount of water that is useful for humans is being used faster than it can be cleaned and put back into the environment.
Now, knowing the facts about water, it is our job to make sure we use Earth’s water in a good way.
1. Where can 96.5% of the water on Earth be found?| A．In oceans. | B．In lakes. | C．In glaciers. | D．In rivers. |
| A．The amount of water becomes smaller. | B．The amount of water stays the same. |

| B．Most fresh water is found in the ground easily. |
| C．Humans can’t use 2.5% of the fresh water freely. |
| D．Water for humans can be cleaned and recycled fast. |
| A．The reasons why Earth is in different colors. |
| B．The people who use the most water on Earth. |
| C．The amount and different types of Earth’s water. |
| D．The proper ways for people to use fresh water. |
