话题一 事物介绍
Passage 1
As the science and technology is developing so fast, great changes have taken place in our daily life, especially the way to buy things. It is so convenient and fast to pay that we just need a smart phone, fingerprint, or even to put our faces in front of a camera. However, how did people buy things in the past
Between 11,000 and 6,000 years ago, people started exchanging animals and food to get the things they needed. It is named bartering(以物换物). People bartered one thing for another. Here’s how it worked in the beginning.
Around 3,000 years ago, people thought that shells(贝壳) were a good form of money. Why The reasons are simple for people then. Shells are beautiful and hard. They don’t break easily, so they can last a long time. People can’t find shells everywhere, which makes them valuable. If people wanted something, they would pay shells for it.
Next, about two hundred years later, the first coin was invented in China. The coins were made out of metal. Nowadays, we have small and round coins. But in the old days, they were made into different shapes in different centuries.
About 1,200 years ago, the Chinese were the first to print money, but it wasn’t paper money. They used leather(皮革) which was made from the hides of animals. It wasn’t until the seventh century that they decided to use paper. At last, the world had its first paper money. Paper is lighter than the coins and they can be carried more easily, so people like it very much. If you had paper money, you wouldn’t need so many coins. Strangely, it took much more centuries for other countries around the world to start using such money.
Thanks to the development of technology, we still have paper money and coins, but now we also pay for things electronically.

How do you describe the surface of one thing Round Square Or smooth You may have different answers. But we know that we can describe the earth’s surface through landforms(地形).
Landforms are made by some kinds of forces. These forces could be wind, water or ice. And it usually takes a very long time to form different landforms. It could be hundreds or thousands of years or even longer. For example, you may see many valleys. It used to be a high hill, but with time going by, water and wind wear down high land into a plain, and then create valleys. Many landforms are formed by water.
There are some main landforms: mountains, valleys(峡谷), plateaus(高原) and plains(平原). There is no standard geological(地质学的) meaning for mountains. But it is usually thought as a landform that rises above anything around it. Often, mountains in the deep ocean are higher and greater in size compared to the mountains standing on the land. Valleys lie between hills or with many high mountains around. And there is usually a river at the bottom of the valleys. The lowest parts of the valleys are lands where good crops or plants can grow well. Most of the valleys on land are made up of running streams and rivers. Plateaus can be seen in every continent and cover almost one third of the earth. The Qinghai-Xizang Plateau, located in central Asia is the highest and the largest plateau in the world. Low plateaus make up good farming places whereas high plateaus are considered great for animal farming. Plains are the most important landforms found on the earth. They are lower than the land around them and can be found both inland and along the coast. A quite large parts of plains are covered by grasslands with deep and good soil. That is why plains are called as the “food baskets of the world”.

保护水足迹
We need fresh water to live. But most of the Earth’s water is undrinkable. Only a small part of the planet’s water is fresh. But most of that is undrinkable, too. Some is polluted and less clean than before. Some is in ice caps. Some is stuck in the atmosphere (大气层). Tabitha Kho cares about saving water. And once he interviewed an expert, Rick Hogeboom, about this topic.
“We simply shouldn’t use more water than we need for living,” Rick Hogeboom says. He leads the Water Footprint (足迹) Network. “Unluckily, the water is running out. In many places, people are using much more water than they need. The problem needs to be solved quickly. We must find a good way before the problem becomes more serious. Everyone should have the responsibility to do something they can do.
However, there is a piece of good news. We can help protect the water. One way is to pay attention to our water footprint.
What’s water footprint It means how much water people use. It helps us understand how our limited freshwater resources are being wasted and polluted. It includes both direct and indirect use. Direct water is water that comes out of our taps. We might use it to wash our hands, take a shower or do the dishes. What’s more, we drink it. While direct water is only a small part of what we use. In fact, we use most water indirectly to produce goods and services. Food makes up the biggest part of our water footprint. In the United States, clothes shopping can also make up a large part of our water footprint. A single pair of jeans takes almost 2,000 gallons (加仑) of water to produce.
We must think carefully about our water footprint. In that way, we can make sure all people can get fresh water.
Passage 4
As time goes by, climate change(气候) is becoming more and more serious. It leads to many natural disasters, like floods(洪水), too hot or too cold weather, sea level rise and so on. All of these make animals and human in great danger. Let’s look at how birds are influenced by climate change.
It is known to all that climate change has greatly influence on the birds’ living environment. Take Poyang Lake as an example. As an important habitat(栖息地) for seriously endangered birds, Poyang Lake has experienced unusual rises and falls.
“In some years, the lake experiences floods, while in other years, it experiences a shortage of rain. Under these situations, what birds can eat in their habitat become less and less,” Qian Fawen, a leader from the National Bird Center of China told China Daily.
To solve such problems about the birds’ habitats, China has tried its best to take actions. It has named 1,140 places these years as important living and wintering places in wetlands. To protect China's wetlands, a law was also made in 2022 to control human activities at important national wetlands and stop harmful activities. According to the law, people can't overuse the wetlands. What’s more, they can’t pour(倒) waste water into the wetlands. Of course, the travel to these places are also controlled. There is only a short time when they can be visited. Some key protected wetlands won’t open to the public.
Since these methods worked well, more birds have been seen wintering in the nation’s wetlands. In February, Hunan Province reported that 72 kinds of waterbirds had spent the past winter at Dongting Lake, and that one endangered kind of bird had become more and more—from 300 in the1980s to over 5,000 now. All of these cases show a better future.

Passage 5
The population of India has become larger than that of China in 2023, making it the most populous country in the world. Earth is getting more crowded as the world’s population is still growing. However, the growth may not last forever.
While the world’s population is still growing, its growth rate(率) is at its slowest since 1950 because of fewer babies, said the report. Fertility(人口生育) has greatly reduced in recent years for many countries. Today, two-thirds of the world’s population live in a country or area where lifetime fertility is below 2.1 births for each woman. A population with this kind of birth rate and low mortality(死亡率) would not change over time. It would stay about the same.
A low birth rate means fewer young people to care for the growing aging population worldwide. By 2025, the world should expect to see far more people with gray hair living longer. The share of the world’s population aged 65 or above is expected to rise from 10 percent in 2022 to 16 percent in 2050. Life expectancy(寿命) could go up to 77.2 years in 2050 from 72.8 years in 2019 throughout the world. However, where you’re born can decide your life expectancy. In 2021, life expectancy for the least developed countries is 7 years less than the world average.
By comparison, eight countries should see more than half of the world’s population growth up to 2050. These include the Democratic Republic of Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania.
Liu Zhenmin, an official from UN, warned that the fast population growth in these areas makes it more difficult to end the problems of being poor and fighting hunger and poor condition of health caused by a lack of food.
话题四 传统文化
Passage6
Tai Chi has always been a symbol of Chinese culture and is becoming popular around the world. According to Xinhua, this ancient martial art is practiced by over 100 million people in more than 150 countries. It was recently added to UNESCO’s Intangible Cultural Heritage List(非物质文化遗产名录).
One thing that makes Tai Chi popular is its health benefits. As you move, you breathe deeply and naturally, focusing your attention, just as in some kinds of meditation(冥想), on your body. This helps you relax and find peace in your heart.
According to Harvard Health, Tai Chi is suitable for almost anyone. This is because its movements are never forced—the muscles are relaxed rather than tensed, and the joints(关节)are never fully bent(弯曲的). It is all gain and no pain.
What makes Tai Chi even more interesting might be the philosophical(哲学的)ideas behind it. The term“Tai Chi” comes from Taoism,which states that inaction(无为), as opposed to action, is the solution to problems. That’s why Tai Chi movements are slow and soft. It is not used to fight an enemy—it is used to protect yourself. That doesn’t mean it is weak though. The principle(原则)of Tai Chi is to use softness to beat hardness.
Tai Chi also focuses on harmony between yin and yang. For example, if you work too hard and feel tired, you have too much“yang”. So it’s time for you to calm down and get more “yin”. This idea of keeping a healthy balance can be applied to almost everything in life. It makes Tai Chi far more than just another martial art.

入乡随俗
Tasting international food in different countries is one of the greatest things of traveling. But as a visitor to a new country, you may worry that you don’t know table manners when you eat out. Let’s look at common restaurant customs in the following countries, which will be helpful to you.
France
In France, it’s important to be on time for your restaurant booking. Call the waiter politely: never shout loudly to get his or her attention, and use “please” in every sentence. You should order your own main dish, as it’s considered impolite to share one dish with others.
Italy
At an Italian restaurant, a waiter will seat you. It’s fine to share food, but don’t make any special requirements when ordering a dish, like asking to add no sugar. However, if you happen to have any dietary restrictions(饮食限制), you can tell them. They are sure to make you satisfied about your meals. Try to finish all your food and do not ask to take leftovers(剩余物)home. So you’d better avoid ordering too much food at a time.
Thailand
At a formal(正式的)meal, it’s certain that you’ll be told where to sit. Get your waiters’ attention by waving your hand. Like Italian restaurants, sharing food is perfectly great. If you’re with a group, the elder women usually order dishes for the table.
When you go to these countries, keep in mind this knowledge. Then your trip will be full of delicious food and good table manners.

Passage 8
外文素材改编自Reader's Digest
凡人之性成于习
Did you fail an exam because you played video-games and did not get ready for it Did you eat ice cream when you try to lose weight As you see, a bad habit is not simply about smoking or drinking. It is about all actions bringing bad results. If you realize the bad influences, start getting rid of the bad habits now.
Make it clear why you have bad habits. It is a fact that you can’t truly break bad habits unless you know what makes you do it. Find out under what conditions you start overeating or drinking a lot. When you realize what forces you to do these actions, take pains to prevent it.
Make your goal visualized(使形象化的). For example, if you want to be thin and healthy, use a software for modifying(修饰)the picture to create a perfect photo of yourself, which may encourage you to insist. Every time you want to eat a cake, look at the picture and you will give it up.
It is helpful to replace a habit with a better one. For example, if you drink soda all the time, replace it with water. It will be a great way to help you break bad habits. Meanwhile, it can also help you find a new field that you may love.
Do not fight against bad habits alone. It is so easy to smoke when nobody knows about your decision to give up and nobody supports you. You can ask your friends to watch your progress. For example, if you fail, you have to pay them or meet their wishes. It will help you get rid of bad habits.
Passage 9
外文素材改编自THiNK
Ask an adult, “What do teenagers do in their free time ” Most adults’ answers will probably include playing video games, watching movies or TV and hanging out with friends. They probably won’t include reading.
Most of these answers are wrong. Fewer teenagers watch TV or movies these days. They even hang out with friends less often than before. Usually when they are playing their mobile phones or watching some websites on the Internet, parents often think they are playing games or chatting with their friends. But in fact, they are reading in the way they like. They don’t read often. They read all the time. Even they read more often than their parents did. And they aren’t only reading books.
Teenagers read e mails and messages. They read articles on websites and posts on social media (媒体). They get a lot of reading practice. Parents are afraid of that it’s not the right kind of reading practice, though. They believe that books are better.
Any kind of reading is good for teenagers. It helps them develop skills that they will need later. Their memories will become stronger and their vocabularies will increase. Online, they can search for many different things to read. They can find the latest information fast.
However, books are still better. They are easier to focus (集中) on. Teenagers understand and remember more from them. Also, reading books helps teenagers avoid social media. Using social media too much causes stress and depression (沮丧)．
Parents can help their kids read books more often. First, they should put the books in the places that can be easily seen and gotten around the house. Then, they should read to their kids or give them time to read. Finally, they should read books of themselves. Kids will learn the habits what they see.
话题六 生活百科
Passage 10
Without the sun, no living things can live on the Earth, including humans. The sun makes plants grow and produce food. At the same time, it can help your body get vitamin D, which makes you stronger, especially good for your bones. However, after spending long hours in the sun, you may feel tired. Then, why does this lifegiving star also make you feel tired
There are a few reasons to explain this thing. The first one is that your body does not want to heat up, so it has to use a lot of energy to cool itself down and remain its common temperature 37℃. If you feel too tired in the sun, it’s a sign that it is time for you to take a break and cool down.
On the other hand, the second reason is short of water. When you stay under the sun for some time, you will sweat(出汗) a lot, and your body will lose much water. As a result, your blood becomes thicker, which makes it harder for your heart to send blood. And it means that less O2 will be sent to your body. If your body doesn’t have much O2 inside, you will feel even more tired. This is also why people should drink water after doing sports.
Next, the third reason is sunburn, which is your skin’s reaction(反应) to the UV(紫外线) in sunlight. As a form of protection, your skin turns red, but this is also tiring for your body.
As you can see, the sun is not only your enemy but also your friend. Warming rays are good for you, but tiredness is your body’s way of telling you that it has enough sunlight in the day. So you should have a good rest.
