Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life. Many birds and animals lived beside the water, which was full of fish. But the lake water is polluted now.
How did this happen? First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past, there were forests all around Lake Ponkapog, so the rainwater was clean.
Now there are many homes around the lake. People often use chemicals(化学物品) in their gardens. There are also many factories. Factories use chemicals in their machines or shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from homes and factories and then carries them into the lake. They pollute the water and kill the animals.
Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But oil and gas from boats often get into the lake. So more bad chemicals go into the water this way.
People in Hartwell are worried. They love their lake and want to save it. Will it be possible?
A clean lake must have clean rainwater. Clean rainwater is possible only if people are more careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals on the ground. And they mustn’t use motorboats any more on the lake. All these may change people’s lives. Only then can Lake Ponkapog be a beautiful, clean lake again.
1. Which of the following can not pollute the water in Lake Ponkapog?| A．Rainwater from the forest. | B．Oil and gas from motorboats. |
| C．Chemicals in people’s gardens. | D．Chemicals from the factories. |
| A．They should use less water. | B．They should grow fewer plants in the gardens. |
| C．They should be more careful about chemicals. | D．They should use more motorboats on the lake. |
| A．Motorboats on Lake Ponkapog. | B．Many big factories in Hartwell. |
| C．Rainwater from many places. | D．Why the water is dirty in Lake Ponkapog. |

【推荐1】The Amazon rainforest covers 5.5 million square kilometers. That’s about half the size of China! However, according to a new study, the Amazon rainforest may become grassland (草原) in a few years.
The Amazon is the world’s biggest rainforest. Climate change and human activities make it “sick”. Usually, the rainforest can fix itself. But now, it feels too “tired” to get better. The trees may die and the rainforest could turn into a hot, dry grassland.
Why is the Amazon “sick”? The Amazon is one of the world’s wettest places. But since 2005, three droughts have hit the rainforest. They were caused by climate change. The trees don’t have enough water to grow. What’s worse, as they become dry, they can easily catch fire.
On the other hand, people cut down rainforest trees for wood. They burn the forest to make farmland. They clear trees to find minerals (矿产). All these activities have caused about 17 percent of the rainforest to disappear.
The Amazon is like the lungs of our planet. The rich plants there take carbon dioxide (CO₂) out of the air and make oxygen. They make more than 20 percent of the planet’s oxygen. What will happen if we lose it? If the Amazon “dies”, there will be more CO₂ and our earth will become even hotter.
Also, the Amazon is home to over 3 million animals and plants. Many of them can’t live anywhere else. They would very likely just disappear.
1. If the rainforest can’t fix itself, what will the rainforest turn into?| A．Deserts. | B．Minerals. | C．Grassland. | D．Farmland. |
| A．The trees. | B．The three droughts. | C．The rich plants. | D．The world’s wettest places. |

【推荐2】You probably see a lot of things made of plastic, like bottles and bags. What happens when the plastic was thrown away? Scientists say that much of it reaches the oceans in the end, and causes problems for ocean creatures (生物), like fish and birds.
“Plastic makes ocean creatures in danger, some of them die when they are tangled (被缠绕) in pieces of plastic, and others eat the plastic and die, too.” says Allison Schutes of the Ocean Conservancy, a group that protects oceans.
A recent study shows that lots of plastic reaches the oceans each minute. Scientists predict (预言) that by the year 2050, our oceans will have more plastic than fish.
Most scientists say taking out all the plastic that has already in the oceans is impossible. Instead, they say the best way is to stop more plastic from reaching the oceans.
Many groups are taking action. They pick up litter before it reaches the oceans. ▲ , volunteers from the Ocean Conservancy collected more than 16 million pounds of litter last year.
Experts also encourage people to use less plastic. Many cities and towns in some countries have banned plastic bags. Experts also suggest that people should use more reusable bottles and bags.
“These seem like small things,” says Schutes, “but they can help to make a big difference.”

For almost 100 years, the Winter Olympics have been a celebration of ice and snow sports around the world. It is a special event that only takes place once every four years.
Although the Winter Olympics started with just five sports across nine disciplines（分项）in France in 1924, it has grown to include seven sports across 15 different disciplines and has been hosted in 12 countries across three continents（洲）. In 2022, for the first time ever in the games’ history, Beijing became the first city to host both the Summer and Winter Olympics.
China has come a long way and achieved many goals since it took part in the Winter Olympics for the first time in 1980. In this short period of time, China’s athletes have won medals in six of the sports events. Short track speed skating（短道速滑）has been an area of expertise（专长）for China.
China’s love for winter sports has been growing. The Ministry of Education has set a goal of building 5, 000 special schools by 2025 to improve winter sports education. The government has also been encouraging primary and secondary schools to add winter sports to their courses. Many provinces and cities have already acted on this suggestion. Classes will be set up in schools in northern China to boost interest in winter sports. In southern China, schools can partner with ice rinks（溜冰场）and winter sports clubs.
Beijing has already set a good example. Nearly 840, 000 students in the city have begun taking winter sports lessons, including skating and skiing lessons, China News Agency reported.

【推荐2】The lion dance, a form of traditional dance in China, can date back to the Three Kingdom Period (220—280). It was very popular during the Tang Dynasty (618—907). The lions looked powerful and a little scary. Chinese people believe that lions can drive away bad luck and bring good luck. Many also think that the animal is a symbol (象征) of China. That’s why lots of people, including overseas Chinese, love this dance so much.
There are different lion dances in different places. It’s called Xingshi in Guangdong. In 2006, Xingshi was added to China’s list of national intangible cultural heritage (国家级非物质文化遗产).
Wang Rentao has been performing the lion dance for 28 years. He is now head of a lion dance team in Guangdong. Last year, the team took part in the celebration of the 74th birthday of New China at Tian’anmen Square. It is famous for dancing on quincuncial piles (梅花桩), one of the most difficult lion dance skills. Dancers jump from one pile to another at a height of about 2.5 meters. The piles are l.8 meters away from each other. “The training is really hard. All dancers can play Kung Fu. Even with that, they may fall from the pile and get hurt,” Wang said. “It can take many years to learn the skill. But that’s also the amazing part of lion dance, the part that makes it valuable heritage.”

【推荐2】Everybody knows that Earth spins from west to east. That is to say, it appears to be spinning counterclockwise(逆时针)when viewed from above the North Pole.
But what if Earth started spinning the other way?
Scientists from Germany have made a computer simulation(模拟)in which Earth spins in the opposite direction-clockwise when viewed from above the North Pole. This showed them some interesting things about the weather and topography(地形地貌)on Earth, live Science reported.
As Earth spins in a counterclockwise direction, it shapes ocean currents(洋流).The direction of the spin, together with wind, produces different weather around the globe(全球).
But a backwards spin changes the ocean currents and winds. Therefore, the climate(气候)is different. Western areas of continents(大陆)on Earth cool down as the eastern parts warm up. Winters become even colder in northwestern Europe, while eastern Russia becomes warmer than before. Rain no longer falls on the planet's wettest places.
Another result of a backward spin is that Earth becomes greener. Scientists found that global desert(沙漠)areas reduce from 42 million square kilometers to 3l. million square kilometers. This may have something to do with the changing climate.
Therefore, you can see rich green landscapes from Central Africa to the Middle East, which are mostly covered by deserts now. More surprisingly, the Sahara Desert becomes an oasis(绿洲).
_______ . They just appear in some places that they never appeared in before. Deserts would cover North America, where countries like the United States and Canada lie. Sand dunes(沙丘)would replace the Amazon rainforest in South America.
A backward spin would keep the major characteristics of Earth's topography, such as the size, shapes and positions of continents and oceans. But it would also change the interactions between circulating(环流)air, ocean and topography, lead scientist Florian Ziemen told Live Science.
1. Why would the climate be different if Earth spins backwards?| A．Because there won't be any more large oceans. |
| B．Because the ocean currents and winds will be changed. |
| C．Because it will change the amount of sunlight that Earth can receive. |
| D．Because Earth will become greener without deserts. |
| A．Winters will become colder. | B．No rain will fall in summer. |
| C．Eastern Russia will become warmer. | D．The Sahara Desert will become smaller. |
| A．Earth used to spin in the opposite direction |
| B．a backwards spin would cause interesting changes on Earth |
| C．global desert areas have become smaller |
| D．a backwards spin would change Earth's topography completely |
| A．Sadly, deserts would cover North America. | B．Luckily, deserts would disappear(消失). |
| C．Anyway, deserts would replace the Amazon rainforest. | D．However, deserts don't disappear. |
【推荐3】Beijing Opera is the most representative of all Chinese traditional dramatic art forms and the largest Chinese opera form. Having a history of about 200 years, it is developed from absorbing(吸收)many other dramatforms, mostly from the local drama 'Huiban', which was popular in South China during the 18th century. It is a scenic（戏剧的）art integrating music, performance, literature, aria, and face painting.
Theatrical art forms in many other countries do not present singing, dancing and spoken parts in one single drama. An opera singer, for example, neither dances nor speaks on stage; there are no singing or dancing parts in a modern play; in a dance drama, the dancer has no speaking role and does not sing either. Traditional Chinese drama, including Beijing Opera, is a kind of entertainment which includes spoken parts, singing, dancing and acrobatics.
In addition to its presence in China, Beijing Opera has spread to many other places. Mer Lanfang, one of the most famous performers(表演者)of all time, was the first to introduce Beijing Opera to foreigners and made highly successful tours to foreign countries.
“You will be puzzled(困惑)all the way through and a little bored from time to time; but you will be charmed and interested. You will be strongly attracted to Beijing Opera even if you know nothing of the dramatic background. "This is how one American traveller described his first experience in watching Beijing Opera.
Beijing Opera is China’s national opera and it is full of Chinese cultural traditions. Welcome to China and enjoy Beijing Opera!
