3 . Pret A Manger looks like any traditional London sandwich shop. It features freshly prepared sandwiches, salads and coffee. But it is not your usual restaurant; it is a food shop with a mission. The company has been giving unsold food daily to the homeless since the first shop opened in 1986. It started small with just a handful of sandwiches but has grown to over three million meals across the UK every year.

Pret A Manger also has a Rising Star Program. For those with a bad record or without a home address, it's tough to find a good job and have a fresh start. Since 2008, the program has opened the door to over 500 people, offering jobs in local Pret shops. The program takes on 40 rising stars every year and so far has helped 462 people and has an 80 percent success rate since it began.

This project is managed by The Pret Foundation, an international charity that was founded to help the homeless and is funded by private donations and the sale of the shop's products. "When we set up The Pret Foundation, we want to break the cycle of homelessness so that the homeless can live on their own and no longer lead a poor life. To do that, we believe that people need three things: food, work and a place to live, " said CEO Clive Schlee.

Now Pret is doing even more for the homeless. It has partnered the West London Mission to open a new home for the homeless. The home can hold up to 13 people at a time who will live there for 6-12 months before moving into a privately rented home. The program provides more than just a place to live, and the participants will also get expert advice to help them know how to live off the streets. Each of them will be offered guidance on necessary skills like opening a bank account, reading and writing, and computer skills.

It's estimated that two-thirds of people online have had their personal information     1    (steal).

Faced with such a range of     2    (threat), it's easy to focus on technology investment. Firewalls, anti-virus protection and every other kind of technology can be threatened as well. That's not to say that     3    (invest) in IT security isn't important. But the cybersecurity (网络安全) threat needs individuals     4    have skills, talent and experience     5    (bad). Indeed, there will be a global shortfall of 3. 5 million cybersecurity jobs by 2021.

Only with people power can we win the online security war. Here     6    (be) the main reasons and methods.

First of all, it is important to improve the security     7    (aware). Security is becoming important, with organizations starting to understand the big role that individual employees must play.

Secondly, pay attention     8    grassroots education. As we face a significant skill shortage in the future,    9    is of great importance that together we help create the next generation of cyber defenders now.

Thirdly, encouraging skilled staff also matters. Most organizations have concerns about security skills, and two-thirds have trouble     10    (encourage) the security staff they have.

5 . For 300 years, the Slims River had been flowing through Canada’s Yukon region. But last year, in only four days, the water in the big river reduced sharply, which made the river almost disappear. What happened?

After a year of careful studies, a group of scientists recently said that the sudden change of the river was caused by climate change. The Slims River used to be a big river, reaching up to 150 metres at its widest points. It carried melt water from the huge Kaskawulsh glacier(冰川) into the Kluane River, then into the Yukon River toward the Bering Sea.

But in spring 2016, there was a sharp melting of the Kaskawulsh glacier because of climate change. It made the melt water run in a different direction, and into a second river, the Alsek River, then into the Gulf of Alaska. It is thousands of kilometers away.

In geography, this is called “river piracy”. Although it was not unusual in ancient times, this is the first time it has happened under scientists’ noses in modern times. The Slims River is almost dry now, which also takes away the clean air in the region because strong wind blows up all the dust in the river bed. Fish have already swum to other rivers. And sheep from Kluane National Park are now coming down to eat the fresh plants.

Lonnie Thompson, a scientist from Ohio State University, the US, said that we could hardly feel the effects of climate change in our daily life, but the case of the Slims River shows what will happen when gradual temperature increases.

1. Why did the Slims River almost disappear?

A．Because the air pollution brought more rain to Yukon region.

B．Because the climate suddenly became hotter than before.

C．Because the human activities destroyed the banks of the river.

D．Because the Kaskawulsh glacier did not exist any longer.

2. Which of the following statements is true according to the passage?

A．The Slims River has now become part of Kluane National Park.

B．The air in the region of the Sli ms Ri ver is still clean.

C．Climate change has no effect on our daily life.

D．Global warming can bring sudden changes to the environment.

3. In which direction did the water run in 2016?
① the Kaskawulsh glacier        ② the Gulf of Alaska
③ the Yukon River              ④ the Alsek River
⑤ the Bering Sea              ⑥ the Kluane River

A．①→④→②	B．①→③→⑤
C．③→⑥→⑤	D．⑥→③→②

4. What may the underlined part “river piracy” in Paragraph 4 mean?

A．A river suddenly disappears without any reason.

B．Two rivers join together to make a bigger one.

C．The flow of a river is suddenly taken away into another.

D．The water in a river reduces sharply.

6 . Artificial intelligence (AI) （人工智能）is the ability of a computer program or a machine to think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with the name "artificial intelligence" in 1955. Many things such as learning and problem solving can be done by computers, though not in the same way as we do.

An unusual goal of AI research is to create computer programs that can learn, solve problems, and think logically（逻辑地）. At present we use the term Al for successfully understanding human speech, recognizing（识别）human faces, operating self-driving cars and competing in some game systems like Chess and AlphGo（阿尔法狗）. Some people also consider AI a danger to humans if it develops too quickly. Professor Stephen Hawking, a well-known British scientist, was not for this kind of technology.

Math is the basic language of AI. If we raise the standard in the learning of math, our students will be more likely to become successful AI designers in the future. We not only want bright students, but also need to attract average students and give them the math skills which are needed to change them into AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.

Scientists hope to create creative and emotional AI which can possibly understand human feelings or create art. Many ways and tools have been tried to discover this fascinating field.

1. From Paragraph 1, we know that_________.

A．all problems can be solved by AI	B．machines with AI can think and learn
