When you think of the Arctic (北极), you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on the earth. We have polluted the deepest oceans with plastic rubbish. And now 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 1,800 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 things made of plastic 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. What can we learn about the Arctic from Paragraph 1?
A.It is an icy land of pure white snow.B.It is a beautiful icy land with clean air.
C.It has been polluted by plastic rubbish.D.It is the last really clean place left on earth.
2. What does the underlined word “contribute” mean in Chinese?
A.增加B.捐献C.造成D.降低
3. How does the writer end this text?
A.By advising us to drink clean water.B.By asking people not to eat sea animals.
C.By showing the beauty of the Arctic.D.By telling the seriousness of plastic pollution.

【推荐1】How do you feel about nature? After spending hours indoors, do you feel better when you visit your local park? I believe the answer must be “YES”.

Most people think that nature is good for our bodies and brains. However, humans are spending more time inside and less time outside. For example, the number of visitors to Canada’s national parks is getting smaller every year. And in countries such as the USA, only 10% of teenagers spend time outside every day. Many doctors feel thatthisis a problem in the twenty —first century.

Therefore, some doctors are studying the connection between nature and health: one example is the work of Dr. Matilda in Sweden. The doctor gave people a math test. During the test, their heart rates (心率) were fast. After the test, one group of people sat in a 3D-virtual-reality (虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than people’s in the other group. The virtual touch with nature helped them feel more relaxed. The natural world allows our brains to rest and slow down, and can leave us feeling happier and less stressed. Another example from Canada also shows nature is good for health. In Toronto, researchers studied 31,000 people living in the city. In general, they found that healthier people lived near parks.

Because of studies like these, some countries and cities want people to enjoy nature in their everyday life. In Dubai, people plan to build a new shopping mall with a large garden, so shoppers can relax outside with trees, plants and water. And South Korea has new forests near its cities and around 13 million people visit these forests every year. Getting close to nature has been thought to be necessary for brain development in children. In Switzerland, “forest schools” are popular. School children study their subjects in the forests and exercise a lot outside. So after building cities for so long, perhaps it’s now time to start rebuilding nature.

In a word, nature holds a special kind of energy: it is clean, wild and spirit —renewing, which makes us grow stronger. ________

1. What does the underlined word “this” in Paragraph 2 refer to?
A.People think nature is good for our bodies.B.People spend more time inside than outside.
C.Only teenagers spend time outside every day.D.The number of people to parks is changing every day.

A.People s heart rates increase in a 3D-virtual-reality room.

3. To help people enjoy nature, countries do the following except ________.

文章大意:本文是一篇说明文。文章主要讲述了利用大数据工作的原理及大数据使用的领域和利弊。

【推荐2】Many of us have had the same “pleasant surprise”. After you mark a song as a favorite on a music app (程序), it suggests songs of the same kind to listen to.     1    

Big data (数据) is a lot of sets of information that are put together so they can be used by a computer program. It can have different kinds of information from many sources (来源), such as information that comes from schools, social media sites, companies, and governments.     2     Another set can have what they like, where they go to school, and how much time they spend on the computer.

    3     The government uses it to understand how many people travel on buses or trains. The information is then used to make bus or train systems better. Companies use big data,too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream.

Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby so he or she does not get sick.     4     It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong.

    5     It is because the computer programs used to look at big data and understand it are written by people. People think a certain way. Because they think a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people.
