1 . If you’re looking to buy a gift for your children, why not keep up with the trend and get the best hoverboard?

What is a Hoverboard?

A hoverboard is a two-wheeled personal transportation device. It’s electrical, portable and became highly popular in 2015. Typically, this self-balancing device operates like a powered skateboard.

How Does a Hoverboard Work?

The device may have many designs, but the mechanism itself isn’t complicated. Basically, a standard hoverboard contains:

•Battery: stores the electrical power. Almost all hoverboards use a high-watt lithium-ion battery.

•Gyroscope (one for each wheel): allows riders to tilt (倾斜) the hoverboard while maintaining balance and adjusting their direction.

•Motor (one in each wheel): provides the power to the wheels to keep the rider balanced and upright.

•Logic board: functions as the hoverboard brain. It processes data—your speed, tilt, etc.—and sends information to the motors. This unit controls the power of the board so riders can adjust their speed.

All the above components work together to control the power and tilt of the hoverboards so the rider is balanced, upright and moving at a controlled speed.

Why Buy a Hoverboard?

Undoubtedly, hoverboards are cool. You’ve probably seen kids riding one around the house. They’re a phenomenon and everybody wants in. So, why deny your kids and prevent them from being part of this trend?

Where is a hoverboard legal?

Despite their wild popularity, hoverboards have yet to become “street-legal”. Currently, some places prohibit anyone under 16 from using these devices, and hoverboards are banned in academic institutions and public places, like campus buildings, parks, shopping malls and subway stations. Some places have also put speed limits on the devices and restricted their use to bike paths. However, open areas—including your yard—are free of these restrictions.

1. The logic board of a hoverboard can ______.

A．store electricity	B．power the wheels
C．send information to the riders	D．receive data and give command

2. According to the passage, you can see a hoverboard ______.

A．on campus	B．in parks
C．on bike paths	D．in shopping malls

3. What is the main purpose of this passage?

A．To evaluate a gift’s quality.

B．To suggest a gift option.

C．To compare new hoverboard models.

D．To explain functions of the latest hoverboards.

Dear teachers and classmates,

I'm glad to deliver a speech about our dream job. Different people have different ambitions. Some wishes to be teachers, while others want to be writers and so on. I am to turn doctor.

In my childhood, I was once taking to a hospital to visit a relative. Watching the patients suffering a lot, I realized that got rid of their diseases was my duty. Since then, I have decided to devote myself to the medical cause. I know what challenging a job it is. I have to spare some effort to enter into a university. Also, a strong body is must. I believe the famous saying: That there is a will, there is a way. I'm sure I will success.

That's all. Thank you.

3 . Do You Have the Time? In English，this question has two different meanings. The first one is "Do you know what time it is?" While commonly，this is less frequently used than the simpler question with the same meaning "What time is it? "The other is "Do you have the time（e.g.to do this or that）? "This is a very commonly asked question，whether in American，British，or Australian English. I think the response" I don't have the time" is most commonly used year after year.    1    

Think about how often you（and I）have used this as an explanation of why we couldn't do something，take on a new task，help someone，visit someone，etc. Sometimes it's a statement of fact，and sometimes it's just an excuse.    2    However，deep down we each have a pretty clean idea of the difference. In practical terns，the lack of available time seems to be and often is a true reason for why we cannot take something on.    3    just don't have the time" is too often an escape. Once we get to a certain age，when we are generally considered to be grown-ups，we are expected to have developed time management skills. In many instances，"I don't have the time" has the same meaning as" I am not willing to make the time". Sure，we're all busy，but in the end，it's a matter of which is more important.

    4    It doesn't grow on trees or fall from the sky like raindrops. You make the time as well as most of the related decisions about what is important.    5     If you don't decide on the use of your time，the decision will be taken away from you. It's really up to us to decide on how to balance and manage time，and that's a challenge.

A．No one gives you the time.

B．After all，it's so convenient as an excuse.

C．The key is what criteria you rely on to make decisions.

D．The distinction here between them is blurry（模糊不清的）and subjective.

E．Actually if we try to rearrange our time，or make a sacrifice，we can make it.

F．But it does mean we need to develop a clear approach to time management.

G．Be aware it's the world's most common excuse，whether you speak it out or not

5 . More and more shoppers are buying things online these days, allowing them to avoid aggressive salespeople and long lines at checkout counters. In spite of online convenience, however, there are some items—like clothes—that customers prefer to examine before buying. In light of this, two companies are Ending ways to modernize stores and bridge the gap between online and in-store retail.

Hointer, a software company that also sells designer jeans, has created a fast and painless shopping experience for its customers. Shoppers walk into a Hointer store and select one of the many pairs of jeans hanging down from bars. Then they point their smartphones at the tag and activate the Hointer app, after which they select the size and press “try on” The app then directs them to a specific dressing room. German-made robots search for the desired jeans and deliver them through a chute to the dressing room in about 30 seconds. Immediately after unwanted pairs of jeans are dropped through another chute, the “outbox”, they disappear from the list in the app.

Purchases at Hointer are made with a swipe of a credit card. And a salesperson is optional. This allows Hointer to hire fewer people and focus on their goal: developing technology that supports a retail revolution.

Men's clothing retailer Bonobos has come up with a more personalized shopping experience. Although it is in fact an online retailer, Bonobos has decided to open a handful of stores called Guide shops. Shoppers make an appointment online before arriving at a Guideship, where they receive one-on-one attention from a fitting guide. Because these shops have limited stocks, shoppers aren't able to take home the clothes they select. But guides help shoppers make online purchases before they leave, after which the items will be delivered to customers in one or two days. Following the purchase, the Bonobos customer service database keeps a record of each shopper's size, making future online purchases easier.

While Hointer focuses on convenience, Bonobos Guide shops focus on customer service. But both efforts have one thing in common: giving clothing retailers a new look for the 21st century.

1. The two companies are finding ways to modernize their stores because ______.

A．online shopping is losing its popularity

B．in-store retail makes higher profits

C．people's demand for in-store shopping still exists

D．store sales keep declining without high technology

2. What do we know about Hointer?

A．It's a software company as well as a jean producer.

B．Shoppers can turn to a salesperson when necessary in Hointer.

C．The Hointer app makes clothes shopping more time-consuming.

D．Shoppers are welcomed by German-made robots in Hointer.

3. If a man wants to buy clothes in Bonobos, it is incorrect that ______.

A．he needs to make an appointment online in advance

B．he has to make online purchases in the store

C．he should help create the customer service database

D．he can receive one-on-one attention from a guide

4. Which might be the best title for this passage?

A．High Technology in Stores	B．Advantages of In-store Shopping
C．Competition between Two Companies	D．New Experience of Shopping for Clothes

6 . The baobab tree is sometimes called “the Tree of Life." Baobabs grow in Africa and Australia. They are the most famous trees in Africa. Baobabs have very thick, wide trunks （树干）.Often the trunks have large empty spaces inside.

In South Africa, one famous tree had a hole so large that someone built a bar inside it. People could sit inside and order drinks. That tree was known as the Sunland Baobab. It was more than 1,000 years old. It was the biggest baobab in Africa. But in 2017 it fell down. In 2016, another famous baobab fell down and died. It was called the Chapman tree in Botswana.

A recent study shows that the problem is widespread. Adrian Patrut and his team started studying the baobabs in 2005.The team found bad news. In the past 12 years, “nine of the thirteen oldest and five of the six largest have died,” the report found. Sometimes parts of the tree didn't die. But the “oldest parts” did.

Experts aren't sure what is causing the baobabs to die. They think it may be related to climate change. But more research is needed to prove it.

The largest trees need more water and food than smaller baobabs. Patrut thinks that is what puts them at greater danger. More heat and less rainfall could have a big influence on the trees.

In Zimbabwe a fungus（真菌）turns baobabs black before they die. But Patrut's study didn't find signs of a widespread disease. No matter the cause, the loss is huge.

Baobabs are amazing. They are a major food source for people. The trees grow white flowers that open at night. Bats spread the pollen（花粉）and help the trees grow fruit. Their white fruit is called monkey bread. People use it as food and to make cool drinks. People make paper, cloth, and even drugs from baobab bark（树皮）.

1. What do we know about the Sunland Baobab?

A．It was the biggest baobab in Australia.

B．It was the oldest tree in the world.

C．It fell down in 2016 in Botswana.

D．It once had a bar inside it

2. What did Patrut's study find?

A．More baobabs are dying,

B．Old baobabs are going to disappear.

C．Trees worldwide have common problems.

D．Trees' living environment is getting worse.

3. As for what's killing baobabs, experts ______

A．are certain human activities put them in danger

B．are sure it is because of climate change

C．have proved disease is the main cause

D．need to carry out more studies

4. What is the main idea of the last paragraph?

A．The great uses of baobab trees

B．The danger of losing baobab trees.

C．How baobab trees help other plants

D．The importance of protecting the environment.

7 . Yesterday, the head of the US federal public health agency said it's on its highest warning level of the outbreak of Ebola in West Africa. More than 930 people are thought to have died from the virus so far in Sierra Leone, Liberia, Guinea and Nigeria.

Ebola can be deadly in up to 90% of cases, depending on the type. The virus is spread through direct contact with body fluids from an infected person. There is currently no known cure or vaccine for the virus.

The reason why the market hasn't produced a drug to battle Ebola is that there are not many people who die from this disease. In the history of this disease, there have been probably fewer than 3,000 known deaths since 1976, among which only one was not in Africa. Besides, most drug companies are interested in drugs that will treat millions of people since it costs hundreds of millions of dollars to develop a drug. However, the U.S. government got interested in this because of its concerns about whether Ebola could actually end up as a terrorist agent. The government think it would be better if they develop some drugs in their back pocket, should somebody try to use this virus to attack people.

Although there hasn't been an effective cure for Ebola, at present there are three different methods to treating this disease. The first is very similar to other anti-viral drugs that are already at the market and this approach is being developed by a company called BioCryst Pharmaceuticals. The second one uses a completely different method, and it uses genetic material that can actually block the viruses’ own genetic material. This is a kind of far out idea and it's being developed by a Canadian company called Tekmira. And the third is a cocktail treatment of antibodies. This was the drug given to the two sick Americans. And it now also has been given to a Spanish minister who got sick while in West Africa.

At the current trend, within another few weeks, there will have been more cases in this outbreak than in all previous recognized outbreaks of Ebola put together. The governments in several countries have now introduced a number of measures aimed at preventing the spread of the virus.

1. Why is American government interested in developing a cure for Ebola?

A．Because they believe it can bring good profits.

B．Because they foresee Ebola may spread in the U. S.

C．Because they think it can help millions of people.

D．Because they find Ebola might be used as a terrorist tool.

2. Which of the following ways probably spreads Ebola virus?

A．Hugging.	B．Kissing on the face.
C．Talking to a patient.	D．Sharing injection needles.

3. The technology of genetic project is applied in ______.

A．the treatment of Tekmira	B．the new vaccine for the virus
C．the cocktail treatment of antibodies	D．the drugs produced by BioCryst Pharmaceuticals

4. What will the author probably present in the following paragraph?

A．The cases of former Ebola outbreaks.	B．The importance of preventing Ebola.
C．The action taken by some governments.	D．More examples of future outbreaks.
