Glaciers are large pieces of ice that form in high mountains or near the poles（极地）over many years. They are made up of fallen snow that gets pressed and move slowly over land. Glaciers are helpful for scientists to learn about what the weather was like thousands of years ago.
Glaciers cover around 11% of the earth’s total land area. They form the largest reservoir（水库）of fresh water on the planet. In fact, they store about 70% of the world’s fresh water. The world’s largest glacier is Lambert Glacier in Antarctica, about 400 km long and 2.5 km deep!
Earth’s glaciers are melting（融化）faster than scientists thought. A study shows that we are losing 369 billion tons of snow and ice each year. Because of warming weather, the melting glaciers are adding more water to already rising seas.
Icebergs are large pieces of ice that have broken away from glaciers and ice shelves. Icebergs float（漂浮）in the sea. Most icebergs are white. There are also blue icebergs. Surprisingly, there are green icebergs in Antarctica. Scientists found green icebergs have 500 times more iron than glacial ice. This is an important finding, as these green icebergs can send iron to far parts of the ocean to tiny sea plants.
We can only see about 10 percent of most icebergs. This is where the phrase “tip of the iceberg” came from, meaning we can only see a small part of a large problem.
Icebergs are dangerous to ships. The underwater ice can easily tear（撕开）a hole in the bottom of a ship. In 1912, the Titanic, on its way to New York, hit an iceberg and sank. More than 1, 500 people died.

【推荐1】Everything has both sides, and space travel is the same. Let’s take a look at the main facts about the future space travel.
1. High Cost
How much does it cost for space tourism? It is difficult to say, but the costs are tens of billions. Of course, rich people can spend so much money on space travel, but imagine if this money was spent on more important things, such as poverty, hunger, medicine, etc.
2. Passenger Health
While astronauts take years to prepare for flights, common people will fly with little training. However, heavy work and zero-gravity conditions (零重力条件) are not good for health. 2 According to a recent study, space travel causes more than a third of astronauts to some illnesses. Here, we are, first of all, talking about cardiovascular pathology (心血管疾病). According to WHO, it tops the list of common diseases. In other words, you need to be not only rich but healthy to fly into space.
3. Environmental Impact (影响)
It burns hundreds of tons of fuel (燃料) for a rocket to fly away from the earth. Of course, people are inventing environmentally friendly fuels, but the flying spaceships are still bad for ozone (臭氧层). So the space travel has some impacts on the environment.
However, although there are so many disadvantages, space travelling will be improved someday. Technology development will not be stopped. In another 5 to 10 years, spending a vacation in space could become as common as taking a taxi or a hotel room today.
1. How much does it cost for space tourism?2. Please translate the underlined sentence into Chinese.
3. Tom has a lot of money. And he is tall and looks strong except mild heart disease. Can he travel to the space?
4. 判断正(A)误(B)。
If the rocket burns environmentally friendly fuels, the flying spaceships aren’t bad for space.
5. How soon may space travelling become common?
【推荐2】Most of us probably live without vegetables, but a world without chocolate? Now that would be hard! According to chocolate makers, it could happen if we don’t act soon.
There are two main causes of the chocolate shortage(短缺)- chocolate’s growing popularity and less production of cocoa, the plant from which chocolate is made. With more and more people in India and China loving chocolate, not much can be done about the first cause.
Therefore, the only thing we can do is to increase cocoa production. However, new plant diseases and little rain in Ivory Coast and Ghana, the world’s largest producers, have reduced cocoa production by 40 percent in the past 10 years. What’s worse, many cocoa farmers in Africa and other cocoa-producing countries like Indonesia and Venezuela are changing to easier-to-grow crops such as corn of rubber. This way, the farmers can make more money.
To prevent more farmers from changing, researchers at the newly opened International Cocoa Control Centre, in the UK, are trying to create new cocoa plants that are stronger and faster growing. But first they must make sure the new plants are safe to grow. This takes a long time.
First, each new plant is stored at the Control Centre for six months to make sure it is healthy. It is then planted in the Centre’s fields, studied and tested for another two years. Only after scientists are certain that they’re disease-free, will the plants be sent to farmers in West Africa or wherever else they are needed.
To create new stronger types of cocoa, scientists at the Control Centre are combing (结合) the best parts from different cocoa plants. Though the world is facing a serious chocolate shortage, there is now hope!
1. In which countries has chocolate become more popular in recent years?2. How long does it take scientists at the Control Centre to make sure a cocoa plant is safe to grow?
3. If you are a cocoa farmer in Africa, will you continue to grow cocoa? Why or why not?
A slow train in Southwest China with its own study room has attracted much attention from netizens (网民), according to a CCTV News report on Monday.
The train No. 5609/5610, which runs between Chongqing and Xiushan county, is a public-welfare (公共福利的) “slow train”. In some carriages (车厢), some seats have been replaced with desks and chairs next to the windows to change it into a “study carriage” for passengers in need. The Chinese characters “Yu Yue” appear on the train, which translates to “traveling and reading happily.” Other inspirational slogans (标语) can be seen throughout the changed carriages.
Besides No. 5609/5610, other “slow trains” have been upgraded with “study carriages”, including No, 5619/5620 and 5633/5634 which run along the Chengdu-Kunming Railway. Students from nearby schools often take the train between school and home. The trains are their “school buses” and many passengers use their travel time to complete homework.
On train No. Z150, which runs between Guiyang and Beijing, a transformed “book bar” carriage has been welcomed by college students. There are nearly 400 universities and colleges in the cities along the line, making train No Z150 the first choice for most students on those campuses (校园). Since 2015, the train’s dining car has been open for free at night to provide returning students with a lending library, free tea and other services. These small measures by the railway department are a welcome comfort for passengers in need of a relaxing place to continue their studies.

【推荐2】Daisy was in the bathroom of her flat. She was brushing her teeth and the tap was on. Water was coming into the sink.
“Turn that tap off,” a voice said loudly. Daisy looked round, but saw no one. “Turn that tap off. You’re wasting（浪费）water,” the voice sounded again.
“Who…who are you?” “I’m water. It’s not easy for me to get here. Do you know where I’m from?”
“From the tap, of course.” said Daisy.
“Yes, yes, but before that?” the voice said, “24 days ago, I was in a cloud in Jiangxi, enjoying the sights comfortably. Then the cloud dropped me into a stream and I ran down the mountain into the Yangtze River. It carried me to a lake. I stayed there for a few days, and then I travelled a long way and ran into the Huangpu River. Then it was time to get cleaned up.”
“Cleaned up?” Daisy was surprised.
“Yes, I was dirty after my journey so they took me to a water factory. They gave me a cleaning and added a few chemicals（化学品）to me. Then I travelled in the pipes under the streets. I waited there until you called me, and here I am.”
Daisy said, “So this is the end of your journey.”
“No. When you’ve finished with me, I’ll go to a sewage plant（污水处理厂）. Then they’ll pour me into the river and I’ll be back in the sea again.”
“Again?”
“Yes. That’s where I came from in the first place. Remember not to waste me or make me dangerously dirty. I’m precious（珍贵）like gold. See you.”
“Wait a minute. What do you mean by that?” But there was no answer. The water left.

【推荐3】The Yangtze River, about 6,300 kilometres long, is the longest river in Asia. It provides a lifeline for hundreds of millions of people. It covers an area of 1.8 million square kilometres, about a fifth of the national total. The river also provides a third of our country’s fresh water resources. Along with the Yellow River, it is considered as China’s “mother river”.
However, in recent years, this “mother river” has met with some environmental problems. It was seriously polluted and the number of the fish is getting smaller. To solve these problems, the government passed the Yangtze River Protection Law. The law came into force on March 1, 2021. There are nine parts in the law, covering areas such as resource protection, anti-pollution measures, green development and legal responsibilities. More importantly, the law has introduced a fishing ban (禁令) on the Yangtze River’s natural waterways. According to the new law, both the central government and local organizations would put the river protection into their economic (经济的) and social development plans.
Around 231,000 fishermen had given up their fishing rights along the Yangtze River. Chinese Vice-premier Han Zheng said that more support should be given to these people to help them find new jobs. He also calls for stronger efforts to help prevent activities which are not allowed by the law and encourages the public to support the ban.

Cooking should be considered as art just like any other activity which requires skills and knowledge. It is often said that students are supposed to learn scientific facts as well as how to prepare meals. The following will explain why cooking should be taught in schools.
Cooking is an important skill in life.
Schools are supposed to teach knowledge to the students so that they can lead successful independent lives when they are out of school. Also, they can step into the world knowing how to make a living.
Cooking helps discover a future career.
When schools offer cooking lessons, students will show an interest in it and might take cooking as a career. This will give them the chance to perfect their basic skills and be creative in the kitchen.
Cooking avoids wasting money.
One of the main reasons why cooking should be taught in schools is that the students always use a lot of money to buy ready-made food, while in the real sense they could prepare a nice meal with less cost by buying the required ingredients.
Cooking betters math learning.
Schools do not just teach how to prepare delicious meals. Students are also taught to follow the instructions without any mistakes when mixing ingredients. If it is “add 1/4 spoon of salt,” students should only add that amount. So there is no more or less.

Good clubs play an important part in helping students develop good habits or interests. Our Power English Club is one of the good clubs.
As we know, language learning needs a long time, and sometimes it is lonely. You need friends, teachers and helpers to encourage you. An English club is your support system. When you feel tired, the members energize you. When you want to give up, the members encourage you. When you have questions, the members give you advice. That’s why an English club is so important.
When choosing an English club, however, it’s very important to find one with positive and friendly members. Unluckily, some clubs are filled with negative and unfriendly people. For example, my brother recently posted his introduction to a football club. After two days, a man responded to him. He told my brother that it was difficult for him to learn football well. My brother felt sad and he didn’t want to learn it again.
Actually if you want to learn something well, you need to join a good club. If you want to join an English club, you need an English learning family that will always encourage you.
Our English club is exactly that. We are very lucky with many wonderful people. Our members are all fantastic. They are clever, warm, friendly and positive. Our members will always make you feel welcome. If you want to join us, we welcome you. Of course, whether you join our club or not is OK. Be sure to find a club that is positive and friendly.

Do you know what is aerobic exercise? It is a type of physical activity such as walking, running, swimming and dancing. It can increase the heart rate. ________ They think it can also strengthen (增强) important parts of the brain.
Research suggests that aerobic exercise helps you learn new things and remember old information better. Because it sends more blood to the brain, and it also feeds the brain with things that develop new nerve (神经) connections. If the exercise has difficult movements like dance steps or basketball moves, the brain produces even more nerve connections. ________
Scientists still don’t fully understand the relationship between exercise and brain power. For the moment, people just have to trust that exercise is helping them to learn or remember. ________ A study in the Journal of the American Medical Association, for example, shows that walking four to five miles (6.5 to 8 km) an hour for 45 minutes five times a week helps you live longer.
