【推荐2】Human activity is changing the surface and temperature of our planet. But new research shows it is also changing the sound of oceans and seas. Scientists say these changes may have an effect on many sea animals—from very small fish to huge whales.

Sound travels very far underwater. For fish, sound is a better way to sense their environment than light. They use sounds to communicate with each other. Sounds also help some ocean animals find food and avoid their hunters. Sounds help fish and other sea animals survive.

However, increased noise from humans is making it harder for these animals to hear each other. The noise comes from shipping traffic, underwater oil and gas exploration and other noisy human activities. For many sea animals, their efforts to communicate are being masked by sounds that humans have made. Experts explain the term masking, which happens when one or more noises in the water block sound that is important to an ocean animal’s life.

Experts say that effects of noise on sea animals are not well understood. However, some studies suggest that noise may cause hearing loss. The stress from human noise might also affect the immune (免疫) system. Many sea animals are showing higher levels of stress because of noise. Also, the overall number of sea animals has gone down by about half since 1970. In some parts of the ocean, scientists now record fewer animals singing and calling than in the past.

When people think of threats (威胁) facing the ocean, we often think of climate change, plastics and overfishing. But noise pollution is another necessary thing we need to consider. When it comes to something humans can do for the ocean, we need to think about how to make it quieter. Sound pollution may be easier to deal with than other ocean threats. You can reduce or turn off sound at once. It’s not like plastics or climate change, which are much harder to undo (消除).

【推荐1】When you think of the Arctic, you imagine an icy land of pure white snow. Others imagine it was the last really clean place left on earth. We have polluted the deepest oceans with plastic rubbish. “And now”, CNN says, “It’s the Arctic’s turn.”

German scientists have recently found microplastics in Arctic snow. Microplastics are pieces of plastic smaller than 5 millimeters. Sadly, the scientists found 1800 pieces of microplastics per liter of (每升) snow.

How is plastic pollution reaching the Arctic? According to scientists, “It’s clear that most of the microplastics in the snow come from the air.” They fall off the plastic objects and are moved by the wind, just like dust. They mix with ice in the air and fall to the ground as snow. Finding these plastics in Arctic snow means that we may breathe them in.

Are they bad for us? Scientists cannot answer this question for now, according to the WHO. We do know that our bodies cannot take in “large” pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, which can be bad for our health. What’s more, earlier studies have shown that microplastics may contribute to lung cancer risk.

Microplastics have also been found in rivers and oceans around the world. Earlier research has found that they flow over long distances and into our oceans, hurting ecosystems along the way. They start in our wastewater, then flow into rivers and out to the sea, where they are eaten by sea animals. If people then eat these animals, it means that we’re eating the plastic as well.

1. We can learn from Paragraph 1 that________.

A．the Arctic is the last really clean place left on earth	B．the Arctic is an icy land of pure white snow
C．the Arctic is a beautiful icy land with clean air	D．the Arctic has been polluted by plastic rubbish

2. The underlined word “contribute” means “_______” in Chinese.

C．From wind.

D．From food.

4. Which of the following NOT true?

A．We may breathe microplastics in Arctic.	B．Microplastics may cause lung cancer.
C．We don’t have to mind microplastics right now.	D．Microplastics have hurt ecosystems.

5. How does the writer end this passage?

A．By advising us to drink clean water.	B．By asking people not to eat sea animals.
C．By telling the seriousness of plastic pollution.	D．By showing the beauty of Arctic.

【推荐3】The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth.

Water Pollution

A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many rivers and lakes are now dead.

Air Pollution

In big cities, factories, as well as cars, trucks and buses are the main causes of air pollution. Many people in cities now have serious health problems. For example, Mexico city used to be a beautiful sunny capital, but today it is always covered by thick brown clouds.

Soil Pollution

In order to have a good harvest, most of the farmers use chemicals too much in their fields. That’s bad for the soil. But this kind of pollution is difficult to stop.

【推荐1】What are you holding in your hand while you are taking the examination? Right. A pen.

Though it is small, the pen has changed the history, improved the trade of countries, recorded events, carried news, and done far more work for human beings than all other tools.

Without it, progress(社会的进步) would have been almost impossible. The invention of the wheel, the introduction of the steam engine (蒸汽机)，the use of electricity, all these have changed the lives of millions of people, but the pen has done more. It has taken away mountains, and it has prepared the way for all progress and development of society.

In the past the pen did all the work if you wanted to keep any writing for some time. The lawyers(律师) took up their pens and wrote the law of the country from the days when papyrus (纸莎草纸) was first used. The most famous letters in the world were written with a pen. It was with a pen that the greatest thinkers of all time wrote down their thoughts.

The pen is very utilitarian. We cannot sign a bill or write 2 letters or buy a house without our pen. An agreement is worthless till our name is written with a pen. The writers encourage the world with it. The students take their examinations with it as well.

Our coming into the world is recorded with a pen. Before we have been at school, our name is written on the name list with a pen. We cannot be married until we have signed. A pen records the important events in our lives.

Let's remember that we hold in our hands the most powerful instrument which man owns. The pen is a magic tool. Whenever you use it, enjoy it.

【推荐2】How nice are you? Do you give money to homeless people? Do you offer your seat to someone in need on a bus?

Many people believe that confident people think more highly of themselves, while those who have low self-esteem（自尊）think less of their good qualities. However, a new study says it might not be true, reported The Guardian.

The study was done by Jonathan Freeman, a psychology professor from the University of London, UK. He found that 98 percent of British people consider themselves to be among the nicest 50 percent of the population. In the study, Freeman first asked some people to rate（评级）their own niceness. Then he got people to answer questions like “Do you give directions to strangers?” and “Have you ever donated blood?”. The results showed that people are not as nice as they think they are. Two thirds of them seldom helped others carry heavy shopping bags, and only a quarter of them donated blood.

In another study by psychologists from universities in Chicago and Virginia, US, some people were shown pictures of themselves. Some pictures had been more or less changed to make them appear more attractive. When asked to pick the unchanged pictures, people usually chose the more attractive ones.

So, why do we think we’re nicer than we actually are? There are many theories（理论）. A popular one says we cheat ourselves unknowingly, so that we can get confidence without lying to ourselves knowingly.

How can we solve it? Other studies show that there is a simple way: feedback（反馈）. Compare others’ opinion toward yourself with your own and you will see a clearer picture.

【推荐2】Boyan Slat has been dreaming of cleaning up the world’s oceans（海洋）ever since he was a child.

In 2010, the 16-year-old boy went on a vacation in Greece. “I saw more plastic bags than fish in the water.” he said. He realized there are more and more ocean pollution these years.

In 2013, Slat decided to clean up ocean rubbish. Now the 25-year-old designed and set up the world’s first ocean cleanup system with his team.

Every year, over 8 million tons of plastics were thrown into oceans, and it needs at least 500 years to reduce the plastic pollution. In 2018, the World anomic Forum said that the weight of ocean plastics will match that of all the fish in our oceans by 2050.

Sea animals can even die if they eat the plastic in the ocean. Smaller plastic pieces car also enter the food chain（食物链）and end up in our bodies.

Slat’s plan was to create a friendly, large system to move away plastic from the ocean. After trying seven years, hundreds of models and many failures, on Oct 2. 2019, a machine called System 001/B came out. It successfully caught and collected much more plastic in the ocean.

Slat and his team are working to improve system 001/B. Their dream is to clean up 90 percent of all plastic by 2040. “In a few years we will have a full scale-fleet（舰队）out there…” he said in public.
