1 . Hall of Human Life(Permanent Exhibit)

Should you have your baby’s DNA sequenced? What keeps you awake? Step inside the Hall of Human Life. the Museums new biology exhibition, and encounter such far-reaching questions on an amazing journey inside the human body. Through digital media and personal interaction, you become “part of the story”, as you contribute your own data in a process of learning and discovery.

A Birds World(Permanent Exhibit)

This exhibit features the Museums extraordinary collection of birds，displaying over 300 species in New England. Here, you can learn to interpret the bird language taking place just outside your window at home.

Test your observation skills and see if you can get past different birds without them alerting(发信号)other animals to your presence. Learn to identify birds from a distance by recognizing unique flight patterns. Practice your flying technique in the Bird Walk.

Butterfly Garden(Permanent Exhibit)

Walk among the free-flying residents of this warm conservatory. It is a wonderful opportunity to get close to a variety of living butterflies from New England and across the globe. The “Emergence Box” offers a window into the butterfly behavior. Look inside to see hanging chrysalides (蝶蛹)transform into adult butterflies. Tickets are required and visitors should reserve at least two weeks in advance.

2 . Like a tired marriage, the relationship between libraries and publishers has long been dull. E-books, however, are causing heartache. Libraries know they need digital wares, but many publishers are too cautious about piracy（盗版） and lost sales to co-operate. Among the big six, only Random House and Harper Collins license e-books with most libraries.

Publishers are wise to be nervous. Owners of e-readers（电子阅读器） are exactly the customers they need: book-lovers with money. If these people switch to borrowing e-books instead of buying them, what then? Electronic borrowing is awfully convenient. Unlike printed books, which must be checked out and returned to a physical library miles from where you live, book files can be downloaded at home. The files disappear from the device when they are due.

E-lending is not simple, however. There are lots of different and often incompatible（不兼容的）e-book formats devices and licenses. Most libraries use a company called OverDrive, which secures rights from publishers and provides e-books and audio files in every format. Yet publishers and libraries are worried by OverDrive’s global market dominance the company can control fees and conditions. Publishers were annoyed when OverDrive cooperated with Amazon, the world’s biggest online bookseller, last year. Owners of Amazon’s Kindle e-reader who want to borrow e-books from libraries are now redirected to Amazon’s website, where they must use their Amazon account to secure a loan.

According to Pew, an opinion researcher library users are a perfect for market for Amazon. Late last year Amazon introduced its Kindle Owners’ Lending Library, which lets its best customers borrow free one of thousands of popular books each month.

Library supporters argue that book borrowers are also book buyers and that libraries are vital spaces for readers to discover new work. Many were cheered by a recent Pew survey, which found that more than half of Americans with library cards say they prefer to buy their e-books.

So publishers keep adjusting their lending arrangements in search of the right balance.

Random House raised its licensing prices earlier this year, and Harper Collins limits libraries to lending its titles 26 times.

3 . Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in our life will be able to talk to each other at lightning-fast speeds with reduced delay. Objectively speaking, the fastest 4G download speeds in the US top out at an average of 19.42Mbps. But by comparison 5G promises gigabit (千兆) speeds.

“5G is one of those heralds (使者),along with artificial intelligence, of this coming data age.” said Steve Koenig, senior director of market research for the Consumer Technology Association. The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane. It could be weather information, and also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need the high speed.

And virtual reality glasses and headsets haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or even replace — smartphones.

Ericsson stated at February's Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.

But don’t get too excited. There’s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn’t concentrated only in big cities.

1. What is the first paragraph mainly about?

A．The security of 5G.	B．The present world of 5G.
C．The future of 5G.	D．The super speed of 5G.

2. Which of the following can replace the underlined word “emblem” in Paragraph 2?

A．exhibition

B．symbol

C．sponsor

D．explanation

3. What do some tech companies expect of virtual reality glasses?

A．They will be heavier than present ones.	B．They will process power on their own.
C．They will bring a big fortune to tech companies.	D．They will take the place of smartphones.

4. What will the author tell us in the next paragraph?

A．How to fully expand 5G coverage.	B．How to effectively reduce 5G trials.
C．How to nicely operate 5G hardware.	D．How to widely construct 5G big cities.

4 . At some point when you were a child,a trusted adult likely told you that if you held a seashell up to your ear, you'd hear the ocean.    1    Seashells are not special capsules that have stored the sounds of their native homes.

But what exactly is that rushing sound you're hearing?    2     “The sound of an empty shell held up to the ear is created by echoes(回声）from sounds made in the environment.”Geerat J. Vermeil, a distinguished professor of Earth and Planetary Sciences at the University of California,told us.

    3    Other structures with openings, like empty bowls or bottles, can produce similar sounds. “When the noise around us hits the internal surface of this hard seashell, multiple reflection occurs,” said Vermeil. “Whether you hold a seashell or the mouth of an empty bowl around your ear, you experience the ocean-like sound quality as a result of a phenomenon called “resonance.”

    4     It says that you're hearing the sound of your own rushing blood in your body. But scientists also clarify that it doesn't change with variation of pulse or blood pressure. “All this is perhaps a bit unimportant, but a more interesting question is what controls the frequencies of echoes" Vermeil added,indicating that there's a need for further research into shape, volume and shell thickness in relation to pitch.     5     Actually, if you put a shell to your ear on the beach, the sounds you hear will include partly some ocean noises.

A．The same goes for shells.

B．The answer is less mystical.

C．This effect is not limited to shells.

D．Now you probably know that this is not true.

E．Scientists are working hard to find the answer.

F．Maybe the original myth is not completely false.

G．There's another explanation for the rushing sound in a seashell.

5 . If Confucius(孔子)were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.

While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually include Chinese art, history and

philosophy(哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks(缺陷)of Western philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

So the old thinker's ideas are still alive and well.

Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

1. The opening paragraph is mainly intended to______________.

A．provide some key facts about Confucius

B．attract the readers' interest in the subject

C．show great respect for the ancient thinker

D．prove the popularity of modern birthday celebrations

2. We can learn from Paragraph 4 that American students___________.

A．have a great interest in studying Chinese

B．take an active part in Chinese competitions

C．try to get high scores in Chinese exams

D．fight for a chance to learn Chinese

3. What is the best title for the passage?

A．Forgotten Wisdom in America

B．Huge Fans of the Chinese Language

C．Chinese Culture for Westerners

D．Old Thinker with a Big Future

4. The passage is likely to appear in__________.

A．a personal biography	B．a history paper
C．a cultural newspaper	D．a philosophy textbook

6 . Anyone who commutes(通勤)by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential backups.

Ants also commute—between their nest and sources of food. The survival of their habitats depends on doing this efficiently.

When humans commute, there’s a point at which cars become dense(稠密) enough to slow down the flow of traffic, causing jam. Researchers wanted to know if ants on the move could also get stuck. So they regulated traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food. Then they waited and watched, trying to find out at what point they are going to have a traffic jam.

But it appears that that never happened. They always managed to avoid traffic jam. The flow of ants did increase at the beginning as ants started to fill the bridge and then levelled off at high densities. But it never slowed down or stopped, even when the bridge was nearly filled with ants.

The researchers then took a closer look at how the behaviour of individual ants impacted traffic as a whole. And they found that when ants sense overcrowding, they adjust their speeds and avoid entering high-density areas, which prevents jams. These behaviors may be promoted by pheromones, chemicals that tell other ants where a trail is. The ants also manage to avoid colliding(碰撞) with each other at high densities, which could really slow them down.

Can ants help us solve our own traffic problems? Not likely. That’s because when it comes to getting from point A to point B as fast as possible, human drivers put their own goals first. Individual ants have to be more cooperative in order to feed the colony. But the research could be useful in improving traffic flow for self-driving cars, which can be designed to be less like selfish humans—and more like ants.

1. What does the underlined word “this” in paragraph 2 refer to?

A．Surviving.

B．Commuting.

C．Finding food.

D．Avoiding jams.

2. How did the researchers control the traffic density of the commuting ants?

A．Through closer observation.	B．By regulating their numbers.
C．By finding out the dense points.	D．By controlling the widths of their path.

3. How can ants avoid traffic jam according to the research?

A．They follow a special route.

B．They level off at high densities.

C．They never stop or slow down on the way.

D．They depend on their natural chemicals to adjust their speeds.

4. Which of the following can be the best title for the text?

A．Traffic jams	B．Survival of an ant colony
C．Unavoidable? Not for ants!	D．Differences between human and ants

7 . One theory is that kissing all began when cavemen began licking (舔) their neighbours’ faces for the salt on them. But whatever it might have been for, the fact remains that, in one form or another, kissing has been widespread, though it developed mostly in the West.

Ancient Greek and Roman parents kissed their children, and lovers or married people kissed each other, as did friends. In the Middle Ages (the period in European history between about 1100 and 1500 AD) knights kissed before doing battle. Early Christians were often kissed to express respect.

Kissing is very much a cultural practice, and rules and attitudes vary across the globe. The French, who have had quite a lot of kissing practice, have turned kissing into a fine social art, although these days, even they are not sure when or how to do it. Many French kiss one another three, or even more, times. It can sometimes go on for a long time. Italians are enthusiastic kissers at all times, and they have been for centuries. Arabic men greet one another with kisses, as do Arabic women. Russian men too are often seen greeting one another with kisses, and it is especially noticeable in the world of Russia, where the three-kiss greeting has become a social behavior. The British, though, remain shy about social kissing. The Japanese, along with many Asian peoples, consider kissing, at least in public, as a Western custom and sometimes even offensive (冒犯的). Kissing has, however, become more commonplace in some Asian countries in the past few years.

But kissing does seem to be on the increase. We kiss people we used to hug, we hug people we used to shake hands with, and we shake hands with those we used to nod to.

1. What is Paragraph 2 mainly about?

A．The importance of kissing.	B．Kissing in the Middle Ages.
C．Different reasons for kissing.	D．The early development of kissing.

2. What can we learn about kissing in France?

A．It influences other countries.	B．It seems a bit confusing.
C．It always changes.	D．It takes less time.

3. Where is social kissing least popular?

A．In Britain.

B．In Russia.

C．In France.

D．In Italy.

4. What does the underlined sentence try to say?

A．Kisses are more welcome than hugs.	B．People’s manners are getting friendlier.
C．Kissing is a better way to show respect.	D．There are many different forms of greeting.

8 . “A blue whale's heart is as big as a Volkswagen Beetle(大众甲壳虫),” I told a group of wide-eyed, open-mouthed second-graders. “It is so big that you could walk around inside of it.” Then I asked a big question-“Why does a blue whale have such a big heart?”—and let the adventure begin.

I was bringing SOLE to my classroom-the Self-Organized Learning Environment.

My students began their investigations and, after 40 minutes, they shared their discoveries.

“Blue whales can call to each other over almost a thousand miles.” said Heavenly. “They need a big heart to talk to each other.”

“They swim all over the world,” said Ki'ara. “So they need a big heart to be their motor.”

“They swim together in pairs.” said Amare. “So they need huge hearts to care for each other.”

“Yeah,” said Isaac. “That's true. It takes a huge heart to care for somebody.”

“Hmmm,” I said. “How can we have big hearts for each other instead of small hearts?”

Then the students made a list of it.

I was teaching compassion—to model ways we can care for each other and other living things. This SOLE lesson took a beautiful turn when Amaze connected the heart of the blue whale to community and to caring.

Perri Klass, in a brief essay for the New York Times titled “Understanding How Children Develop Compassion”, writes about the importance of modeling compassion to children so those things are part of their experience long before they know the word.

Around my school, however, nine out of 10 families live in a destructive poverty that makes it difficult to model compassion, to nurture community and caring. My students often come to school knowing more about the survival of the fittest than the survival of the kindest. Yet here were my 7 and 8-year-olds working together in a community, talking about caring for each other and exploring ways we can have big hearts instead of small hearts for each other.

On that day, the blue whale and the second-graders modeled compassion for all of us. This SOLE lesson brought heart to my classroom.

1. How did the students get the answer in the SOLE class?

A．By looking at a blue whale.	B．By finding the answer themselves.
C．By questioning each other.	D．By taking a dangerous a trip.

2. What was the list made by the students about?

A．The ways to care for each other.	B．The ways to learn from each other.
C．The disadvantages of having small hearts.	D．The importance of having big hearts.

3. What does the underlined part “the survival of the fittest” imply?

A．The students were used to SOLE lessons.	B．The students were mostly from poor families.
C．The students had too much to do at school.	D．The students were fond of working together.

4. Which of the following can be the best title for the text?

A．SOLE Lessons-a Way to Care for Each Other

B．Discoveries about a Blue Whale's Heart

C．How Blue Whales Taught Children about Compassion

D．How Children Learned Science in SOLE Lessons

9 . 3rd Walk the Talk: The Health for All Challenge 2020

JOIN US VIRTUALLY

World Health Organization(WHO)is taking the 3rd Walk the Talk: The Health for All Challenge virtually this year. In the context of COVID-19, WHO, through several online platforms, will host exercise moments, information sessions, and live chats with experts on topics from physical and mental health to nutrition and healthy ageing.

10 . On a bright early summer morning, many young swimmers gather at a local swimming pool in the state of Maryland. They are members of a competitive summer swim team, and that’s a regular part of their daily life. As they train and cut seconds off their times, which makes them closer to the championship in the following large-scale (大规模的) competitions, they are getting lots of physical exercise and vitamin D from the sun. However, the benefits of belonging to a sports team are not just honor or health related. You can learn useful life skills.

Paul Waas, coach of the swim team, explains, “The discipline (自制力) comes into play when you’re talking about concentrating on the details that your coaches are saying as it makes you faster rather than going up and down the pool the same way you have every time. When you focus on what you’re doing right and what you can do better, then you’ll see the improvement.”

Besides, there is also responsibility, goals and workings within a group. Again, here is Coach Waas. “It’s really great! It’s so fun to watch from year to year. I’ve had kids who as 7-year-olds on the team could barely pay attention in practice and were only interested in who was going first. Now they’ve come back as 8-year-olds, having set some goals and having things that they want to achieve. These skills can help them a lot.”

But playing the sports is not without harm. Some can be hard on the body. Young athletes suffer serious injuries that follow them into adulthood. Coach Waas says that in fact, swimming is different from most others. First, it poses a lower risk of injury. The second one relates to how swim teams are structured. Actually, children are not the only ones who can benefit. Adults can also benefit from team sports.

1. Why do the swimmers gather at a swimming pool in the early morning?

A．To obtain vitamin D from the sun.	B．To build practical skills for future.
C．To join in a large-scale competitive.	D．To carry out their routine practice.

2. What do Paul Waas’ words imply in paragraph 2?

A．Swimmers should concentrate on details.

B．Members get disciplined and focused in the team.

C．Coaches play a key role in layers’ improvement.

D．Most swimmers enjoy sinning in the same way.

3. What happens to the kids after a year’s training?

A．They are more aware of what to do.	B．They pay less attention to training.
C．They devote more time to practice.	D．They care more about who goes first.

4. What does the author want to convey in the text?

A．Exercise benefits everyone.	B．Swimming is better than other sports.
C．Team sports teach life lessons.	D．Physical exercise should be a habit.
