5G is developing, but most of us aren't really sure what it is or the reason     1     we need it. A big part of the reason is that 5G means more than one thing. If you ask different people, you     2    (provide) with different answers.

Experts believe that 4G is on     3     way out. In 2020, the U.K. is expected to use 5G. At present, it is unknown exactly what influence 5G will have on people's life but it is widely thought that 5G will     4     (definite) be faster than any generation of networks we have used previously.

Work will likely become much easier as 5G will allow quicker downloads and a better ability to work online even if there is no wi-fi connection. With the     5     (develop) of 5G, driverless cars will be able to communicate     6     other vehicles, which can reduce road accidents by about 10%, One of the most     7     (impress) things will be that people can see which seats on a train are accessible to     8     (they) when it arrives at the station.     9     (get) around the world will also be more convenient.

A number of     10     (company) are now working on bringing 5G to the market. It remains to be seen how much of the country 5G will cover and whether everyone will be able to benefit from it.

2 . Before she could even talk, Ellie Heath spent hours drawing pictures every day. When she grew older, the 15-year-old girl discovered the joy of sewing (缝纫). She said that she found it calming. She started out to make small things, like jewelry and soft toys. Over times, she began making clothing. Her love of the creative work led her to open a business.

4 . Food storing is common in members of the crow(乌鸦）family.A new study tested the birds outside this naturally occurring behaviour,which may have evolved(进化）specifically because it gives crows a survival advantage.Some crow species are known to naturally use tools to recover food.So the researchers tested whether the birds could store and recover a tool so they could get it at their food after a gap of 17 hours-something we wouldn't expect them to do naturally.But they were able to instantly select the tool out of a number of unnecessary items.

In another experiment,the researchers taught crows to select a token(礼品券）from a number of items so that they could then exchange for food.Again,the birds then showed that they could plan for the future using this new behaviour.This is different from all of the previous studies in future planning,which have focused on naturally occurring behaviour.For example,we know that chimpanzees select,transport and save appropriate tools for future needs.

These studies have shown that animals can plan for the future-but they left an important question open for debate.Are animals only able to plan to use abilities that have evolved to give them a specific advantage,or can they flexibly and intelligently apply planning behaviour across various actions? Most critics would say the former,as the animals were tested in naturally occurring behaviors.

But the new research provides the first evidence that animal species can plan for the future using behaviour that doesn't typically occur in nature.This supports the view that at least some recognitive abilities in animals don't evolve just in response to specific problems.Instead,it suggests that animals can apply these behaviors flexibly across problems in a similar way to humans.We need to investigate how flexible behaviour evolved.Then we might be able to see how crows' ability to plan for the future fits in with their broader cognitive powers.

1. What's the new finding about some crows according to Paragraph 1?

A．They can store food.

B．They can use tools to recover food.

C．They can store and recover tools.

D．They can select and store food.

2. What are crows trained by scientists to do when given a token?

A．Reject it casually.

B．Exchange it for food.

C．Save it as their food.

D．Build a nest with it.

3. What do scientists think of the studies that animals can plan for the future?

A．They are debatable.

B．They are disappointing.

C．They are contradictory.

D．They are convincing.

4. What can be inferred about recognitive abilities in animals?

A．They develop only with age.

B．It is unclear how they've evolved now.

C．No animals but crows benefit from them.

D．Planning for the future helps their evolution.

5 . What makes sports fun?

What makes organized sports fun for kids? A group at George Washington University (GW), led by Professor Amanda J. Visek, has been studying this question. The research is important because lots of kids give up playing sports around age 13 or 14.

The reason kids quit?     1     So if the group can figure out what makes sports fun, maybe more kids will play longer and develop better lifelong exercise habits.

First, the group brainstormed 81 things called "fun determinants" that can make sports fun. Then they asked the players aged 8 to 18 to assess how important each thing was to their enjoyment of playing organized sports.     2     The players ranked(排名) “winning” as only the 40th most important fun determinant. Unexpectedly, they ranked "trying your best," "exercising and being active" and “getting along with your teammates" in the top 10 most important fun determinants.

    3     They also compared younger athletes with older athletes as well as recreational athletes and kids who play on travel teams. The recent study revealed (揭露) more surprises. Some people think girls like sports because they want to be with their friends, while boys like to compete.     4     It's true boys placed slightly more importance on "improving athletic skills to play at the next level," but for the most part, the study found male and female athletes’ answers were very close.     5     Although there were some differences between the groups -younger players, for example, like "playing different positions" more than older players-the groups shared lots of the same attitudes toward what makes sports fun.

A．The result was surprising

B．They say sports aren't fun anymore.

C．Boys and girls react differently toward sports.

D．Different groups have different opinions on fun determinants.

E．The group compared males' and females' attitudes on what makes sports fun.

F．The study, however, showed girls' and boys’ attitudes were more alike than different.

G．The same was true for younger and older players as well as recreational and travel athletes.

6 . David Attenborough's Dynasties takes viewers to Antarctica to follow the emperor penguin. Why are there penguins in Antarctica and not the Arctic? The simple answer is that there are too many predators(食肉动物) in the Arctic. Animals who call the Arctic their home include the polar bear, arctic fox, grey wolf, etc. There are not many animals that could kill penguins in the Antarctic, which has allowed the species to survive there.

Different types of penguins can be found in Argentina, Australia, Chile, New Zealand, and South Africa. The only species of penguin that lives north of the equator is the Galapagos Penguin.

Penguins have lived in the South Pole for thousands of years but once actually lived in the Arctic. According to Aurora Expeditions: "During the 19th century, several research groups tried to introduce penguins into the Arctic environment. However, because of the predators, the penguins couldn’t protect the eggs in their nest and the entire population died out after a couple of years.”

A now extinct flightless bird called the great auk was the only modern species in the genus (属) Pinguinus and its natural habitat was the North Pole. Although not closely related to penguins, the great auk shared many similarities such as a physical resemblance and being flightless. The species became extinct in the middle of the 19th century due to predation by polar bears and they were also prized by hunters for their feathers and eggs.

The documentary was filmed at Atka Bay in Antarctica. 11, 000 birds gather on the newly frozen sea ice in Atka Bay every year to face the Antarctic winter. Director Miles Barton said: "I think the film will be a surprise. I don't think anyone has shown just what a huge struggle it is for emperor penguins to bring up their chicks in what must be the worst condition on earth.”

1. What can we learn about penguins?

A．They are nearly extinct in the Arctic.

B．They have no enemies in the Antarctic.

C．Some of them live in the hottest part of the earth

D．Many of them can easily adapt to climate change.

2. What's one reason for the extinction of the great auk according to the text?

A．Hunting.	B．Lack of food.
C．Climate change.	D．Losing their natural habitat.

3. What can be inferred from Miles Barton's words?

A．Atka Bay is the perfect habitat for emperor penguins.

B．Emperor penguins are more aggressive than other penguins.

C．The film focuses on the efforts to protect emperor penguins.

D．It is a challenge for emperor penguins to survive in the Antarctic.

4. What does the text mainly talk about?

A．The protection of the Antarctic.

B．How a film about penguins is created

C．Why there are no penguins in the Arctic.

D．The introduction of different kinds of penguins.

8 . Why Is Exercise Cool?

•Exercise Strengthens Muscles

Did you ever do a push-up or swing across the monkey bars at the playground?    1    By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.

•    2    

Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion”, which means you can move your arms and legs freely without feeling tightness or pain.

•Exercise Keeps the Balance

    3    Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic things.    4    If you’re not very active, your body won’t need as many calories. Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.

•Exercise Makes You Feel good

It feels good to have a strong, flexible body that can do all the activities you enjoy—like running, jumping and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.

But you may not know that exercising can actually put you in a better mood.    5    It’s just another reason why exercise is cool!

A．Exercise Makes You Flexible

B．Exercise Makes Your Heart Happy

C．Those are exercises that can build strength.

D．So you want to do some aerobic (有氧的) exercise right now?

E．But if you’re active, your body needs an extra measure of calories or energy.

F．Food gives your body fuel in the form of calories, which are a kind of energy.

G．When you exercise, your brain releases a chemical which may make you feel happier.

9 . In her 17 years on this earth, Shreyaa Venkat has done more to help the planet and the people living on it than many adults. The non-profit organization she founded, NEST4US, has helped tens of thousands of people in the United States. Through it, it’s served over 12,000 homeless people in the Washington, D.C. area by providing food and other supplies.

Venkat’s passion for helping others started as soon as she could walk, as her parents, active volunteers themselves, brought her along on their various projects, like some creative ways to volunteer. By fifth grade, she’d developed such enthusiasm for it that she started organizing her own service projects in her community.

NEST4US was born when she realized how much food waste there is, how many hungry people there are, and how simple it would be to use the former to help the latter. “There was a homeless man standing on a corner in D.C. and he was holding a sign that said ‘Hungry Need Food’,” she recalls. “So I gave him my lunch and his whole face just lit up. It was so easy, it only took me 30 seconds, and it really helped him.”

As NEST4US took off, with hundreds of volunteers helping to feed thousands of hungry people, Venkat decided to branch out with her volunteer efforts, starting three other branches of NEST4US. Serving others had become such a way of life for her that she even celebrated her 13th birthday at a homeless shelter, bringing the party to them instead of expecting gifts for herself.

As much as she has helped others, they’ve helped her too. Not only does she get a lot of joy and personal satisfaction from her volunteer work but running NEST4US has taught her important life skills like time management, public speaking, writing, and leadership. “What it’s really given me is this opinion of putting other people first,” she says.

1. What can we infer about NEST4US from the first paragraph?

A．Its main aim is to make money.	B．It offers people cheap supplies.
C．It takes in all homeless people.	D．It is a charity organization.

2. What caused Venkat to set up NEST4US?

A．Her parents’ constant suggestion.	B．The memory of her hard childhood.
C．Her experience of helping a hungry man.	D．Volunteers’ great influence on her.

3. Why did Venkat spend her 13th birthday at a homeless shelter?

A．She held a grand party for many people.

B．She could receive many nice gifts there.

C．She got much personal satisfaction from it.

D．She saw helping others as part of her life.

4. Which of the following best describes Shreyaa Venkat?

A．Caring.	B．Ambitious.
C．Humorous.	D．Demanding.
