People have always been defined by their gene...

People have always been defined by their generation. We had the baby boomers of the 1960s, followed by Generation X and then Generation Y, often referred to as millennials, and the new kids on the block are Generation Z - aged between 16 and 22. It's easy to classify these young people as all being the same, sharing the same attitudes towards life—but is that fair?

People from Generation Z, informally called "Z-ers", may be viewed by others as digital natives, incapable of real-world friendships. But they actually view themselves as hardworking, ambitious and about to change the world for the better. The previous generation, born between the mid-1980s and late 1990s - the millennials were also thought to have these characteristics. But many people view this new generation as “mini-millennials" because Z-ers are different and they have their own set of values and preferences which consumer brands need to cater for.

It's true to say that technology is playing an important part in the lives of Generation Z, particularly in the area of social media. In fact, they have not known life without it and using it to communicate, share ideas and campaign is second nature. It means they have more of a say on what we eat, drink and buy than any generation before them. These young people certainly need to be listened to by retailers （零售商） and businesses - they are the people with time on their hands and money.

But being a Z-er comes with pressure. One young person says "Many people in Generation Z have mental health issues because they're unsure what the future will bring." The future always brings uncertainties but maybe there is pressure for this generation to be the most successful ever.

1.When was a Z-er likely to be born?

A.In 1964. B.In 1975.

C.In 1987. D.In 1999.

2.What do Z-ers see themselves as?

A.Diligent and ambitious. B.Hardworking and incapable.

C.Promising and different. D.Stressed and successful.

3.What're Paragraphs 2&3 trying to argue?

A.Z-ers have known life without social media.

B.Z-ers pay too much attention to digital devices.

C.Z-ers and the millennials have the same personality.

D.Z-ers become a key driving force in the consumer market.

4.What docs the author think is the real cause of the Z-ers' pressure?

A.Their ambition to be the best.

B.Their uncertainty of the future.

C.Their addiction to digital devices.

D.Their lack of real-world friendship.

If plastic had been invented when the Pilgrims (清教徒移民) sailed from Plymouth, England, to North America and the Mayflower had been stocked with bottled water and plastic-wrapped snacks, their plastic waste would likely still be around, four centuries later. If the Pilgrims had been like many people today and had simply thrown their empty bottles and wrappers over the side, Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world’s oceans today, waiting to be eaten by unfortunate fish, and eventually perhaps by one of us.

Because plastic wasn’t invented until the late 19th century, and production really only took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a shocking 6.3 billion tons never made it to recycling facilities.

No one knows how much unrecycled plastic waste ends up in the ocean, Earth’s last sink. In 2015, Jenna Jambeck, a university of Georgia engineering professor, caught everyone’s attention with a rough estimate: between 5.3 million and 14 million tons each year just from coastal regions. Most of it isn’t thrown off ships, she and her colleagues say, but is dumped carelessly on land or in rivers, mostly in Asia. It’s then blown or washed into the sea. It’s unclear how long it will take for that plastic to completely biodegrade (降解). Estimates range from 450 years to never.

Meanwhile, ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly-strangled (勒死) by abandoned fishing nets. Many more are probably harmed invisibly. Marine species of all sizes, from fish to whale, now eat microplastics, the bits smaller than one-fifth of an inch across. On Hawaii’s Big Island, on a beach to which no paved road, I walked ankle-deep through mocroplastics. After that, I could understand why some people see ocean plastic as an approaching disaster, worth mentioning in the same breath as climate change.

And yet there’s a key difference: Ocean plastic is not as complicated as climate change. There are no mean waste deniers (否认者), at least so far. To do something about it, we have to remake our planet’s entire energy system.

“This isn’t a problem where we don’t know what the solution is,” says Jambeck. “We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle.” It’s a matter of building the necessary institutions and systems, she says--ideally before the ocean tums, for centuries to come, into a thin soup of plastic.

1.In the first paragraph the author emphasizes the fact that ______.

A.British people migrated to America four centuries ago

B.people have kept doing research in plastic for four centuries

C.there was no plastic pollution four centuries ago

D.plastic waste would remain in the ocean for four centuries

2.How are marine animals harmed invisibly by ocean plastic?

A.They eat microplastics.

B.They drown in microplastics.

C.They are coated with waste plastic bags.

D.They are struggling in abandoned plastic nets.

3.Which of the following statements is TRUE according to the passage?

A.People all agree reducing plastic production is the solution.

B.People tend to agree plastic waste has caused ocean plastic.

C.It has been scheduled to reverse the trend of climate change.

D.It has been scheduled to reverse the trend of ocean plastic.

People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. 1.　 This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.

Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. 2.　 They take up less space in the bottles.

After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. 3.　 The bottles are placed in a large container filled with warm water that is then brought to a boil.

The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. 4.　 In other words, a vacuum （真空）is created.

When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between 4℃ and 21℃.

5. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.

A.The process of canning is much more recent.

B.This makes a strong barrier to keep the air out.

C.One popular method of canning uses a water bath.

D.Firmer fruits and most vegetables are usually cooked.

E.Canning uses heat to kill bacteria that cause poisons to form in food.

F.Then covers are placed on the bottles, but they are not turned all the way.

G.Canning allows your family to enjoy foods that might not come fresh throughout the year.

The way individuals collectively remember, forget, and recall event, people, places, etc, has been an important topic of research on collective memory. 1. He developed the concept of collective memory, arguing that individual memories are only understood within the context of a group through time and space. In all cases, most research on memory studies relies on long procedures 2. They include theoretical concepts, the study of historical sources, oral histories, case studies, interviews, and surveys. For example, one group of researchers carried out several interviews to investigate younger and older American adults for three wars, namely, the Civil War, World War Ⅱ, and the Iraq War. 3. Both younger and older adults recalled the bombings of Hiroshima and Nagasaki; however, they differed in how they rated the bombings.

More recently, memory study scholars tend to stress the significance of the media in shaping collective memories: “Culture and individuals’ memory are constantly produced through the technologies of memory.” Under this perspective, research often involves content analysis of news and the use of surveys or interviews for analyzing the public memory. 4.

During a conversation with someone, you've probably had to compete for their attention with a technological device and lost. Maybe the person in front of you diverted their attention to their latest ''urgent" notifications. They' ve probably even interrupted your conversation to answer a call, answer a text message, or check their social media.

Clinical psychologist and sociologist Sherry Turkle has conducted extensive research on the subject that she shared in her book Reclaiming Conversation: The Power of Talk in a Digital Age(2015). In this book, she stated that teenagers have reduced their empathetic capacity by 40%，as well as their ability to engage in deep conversation, and that cell phones are to blame.

Nowadays, a large part of social and work related interactions occur through electronic means, such as computers, phones, and tablets. Face- to-face conversations have been relegated to the background, and some people even see them as a waste of time. If you have to solve a business problem, you send an email. If you want to ask for forgiveness, you write a text message.

Since facing conflict or emotional situations can generate anxiety, new technologies offer the possibility of reducing some of it. Young people justify using new forms of communication as an easier and faster way to express their thoughts. They say that mobile devices allow them to rewrite what they want to say, correct mistakes, or avoid tense situations that they wouldn't know how to solve in person.

The problem is that screens don't allow us to enjoy one of the most enriching part of conversation: non-verbal language. We miss out on gestures, intonation, looks, and real emotions. This is quite worrying because, according to experts, 70% of communication is non-verbal.

Human interaction has been replaced with “memes" or emoticons. It's even hard for people to maintain deep conversations for extended periods of time. As a result, humans now have a lot of difficulties in managing their emotions, facing difficulties, and carrying out responsibilities. If you don't share content on the Internet, it's like you don't exist. If you don't share your vacation on social media, people may believe that you didn't actually take it or that you didn't enjoy it, Therefore, what you share is a reflection of who you claim to be, but not who you really are.

Under these circumstances, it's harder to empathize with others and put yourself in their shoes to try to understand their emotions and thoughts. The world is becoming purely visual and superficial.

People build and reinforce their connections during face to-face conversations. This is because you can see how the other person feels and listen to their ideas and concerns. You can empathize with them because you can see their joy or suffering with your own eyes.

Deep, personal conversations awaken emotions inside you. They give you a space to open up and vent, to be heard and respected.

1.We can infer from Para.2 that the book.

A.stresses the importance of face to-face conversation

B.explains teenagers' ability to engage in deep conversation

C.analyzes the reasons for competing for others' attention

D.regards face to-face conversation as a waste of time

2.The underlined word ''non—verbal" in Para. 5 probably means

A.foreign B.spoken C.written D.sign

3.The author would agree that social media platforms.

A.promote deep personal conversations

B.help to put yourself in others' shoes

C.don't necessarily show people's true emotions

D.build connections because you can see joys and sorrows of others

Have you ever wondered why there are so many skin colors in the world? Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this.

Skin contains something called melanin, which determines a person’s skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a person’s body will produce less melanin, making the skin lighter.

Skin color is also affected by another source ---- vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark—skinned person will produce less vitamin D than a light—skinned person when they received the same amount of sunlight.

The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.

Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.

The British people have just discovered a new country. It’s called the UK! More and more people are choosing to take their holidays in their own country rather than travel abroad.

In the late 1970s, air travel became affordable for the average family in the UK, and more and more British people started travelling abroad for their summer holidays (July-August). After all, the British weather isn’t very good, even in summer, so a lot of Britons leave the UK for a vacation. Particularly popular with families on a budget is the “package holiday”, where the cost of flights and accommodation are offered as one discounted price by travel agents.

In the 1980s and 1990s, young people in the UK became more wealthy. As a result, the Club 18-30 holiday became popular. Young people started to go abroad in groups, to places such as Spain and Greece. Once at their destination, they socialised with other groups of young people and had one long party.

British holidaying habits have begun to change, however. Climate change means that the UK now has a warmer climate than before, so people don’t always feel they need to go overseas to find good weather. Also, the world seems a less certain place as interconnected economies rise and fall, which means that the cost of foreign holidays is less predictable than it used to be. As a result, more and more Britons are choosing to spend their summer holidays in the UK.

In recent years, British hotels in areas such as the English Lake District have seen a large increase in bookings. That rise is mainly owing to the British staying in their own country for their holidays. In addition, for some foreign tourists, the UK is a cheaper place to visit than previously because of changes in the value of the British pound.

The UK has always been famous for its international explorers, but now it is starting to discover itself.

1.What is the feature of the Club 18-30 holiday?

A.Young people went abroad with their family.

B.Young people got lots of money from their family.

C.Young people took part in social activities abroad.

D.Travel agents offered a better discount to young people.

2.Why do British people prefer domestic holidays now?

A.They are wealthier and more social.

B.The global weather is becoming predictable.

C.The UK is famous for its beautiful scenery.

D.The expense on foreign holidays is unsteady.

3.How is the text mainly organized?

A.In order of frequency. B.In order of time.

C.In order of space. D.In order of importance.

4.What is the best title for the text?

A.Holidays and Habits B.Weather and Scenery

C.Travels and Economies D.Package Holiday and Culture

If, for some reason, you had 2,010 empty plastic bottles, what would you do? You’d probably sell them cheaply, right? But Xia Yu collected 2,010 bottles and built a boat with them. As you read this, Xia is, in fact, on a river somewhere in Anhui, slowly going towards his destination: the Expo Garden in Shanghai. 2,010 plastic bottles were to celebrate Expo (世博会) 2010 Shanghai. On the opening day of the Expo, Xia, together with five friends, went on a 1, 500km journey from Xiangtan to the Expo Garden, in spite of the doubt whether they’ll make it. After all, the boat they are on can hardly be called a boat. It cost only 2,000 yuan to build in a month.

What’s keeping Xia going is a major cause behind the trip. “We are examining water pollution through our journey and trying to promote a low-carbon (低碳) lifestyle. Before we started, no one believed we could sail the boat to the Dongting Lake. But we made it.” But as they expected, the journey has not always been smooth. Of the six from Xiangtan, four gave up. As of the press time (到发稿时), only Xia and his friend Huang Ying were on the boat. Huang suffered from a disease when they reached Jiujiang, Jiangxi province, Xia said, “There are so many things that can stop us from making it to Shanghai, like the weather, health, and sometimes swift river water”.

The boat was produced in a factory according to our design, and perhaps it’s not in a very good condition. But, Xia said, “we are wearing life jackets. Some boats passing by offered help”. What is more of a reward for Xia and Huang is that the Yangtze River turned out much cleaner than they had expected. Although Xia and Huang are uncertain about the journey ahead, they are quite happy with what they have already achieved. After all, it’s not the destination that counts. It’s always the course that matters the most.

1.Xia Yu doubts the success of the journey because of 　　.

A.such a long journey on the river

B.the poor boat and the bad weather

C.few people taking part in the journey

D.the seriously polluted river in some parts

2.Which of the following is NOT the purpose of the journey?

A.To examine water pollution.

B.To celebrate Expo 2010 Shanghai.

C.To win a race on the water.

D.To promote a low-carbon lifestyle.

3.From the text we know that　　.

A.they stay on the boat at night

B.three people gave up due to their bad health

C.Xia Yu and his mate have arrived in Shanghai

D.Huang suffered from a disease on the journey
