Robots make me nervous—especially the ones which seem to think for themselves. I was embarrassed to admit this till I heard that Bill Gates, the founder of Microsoft, felt the same way.

Gates said in an interview with the social networking and news website Reddit: “I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent．That should be positive if we manage well. A few decades after that though the intelligence is strong enough to be a concern.”

Well, maybe I don’t have to worry about my computer and kitchen equipment yet. After I use them I can always pull the plug. But in the future, machines might find a way to prevent us from switching them off. There’s a terrible thought!

Maybe the problem with computers too clever for us is not that they are evil like some we’ve seen in sci-fi movies. What could put us in danger is that they might be too efficient. That’s what philosopher Nick Bostrom from Oxford University believes. He says that machines are indifferent (漠然) to humans and in pursuit of their own goals，the destruction of people might be just additional damage. Bostrom gives us an example: A machine which might have as its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you. Because it is, well, a machine, it would not take pity on you.

It’s a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics. They state that a robot may not hurt a human being or allow the human being to come to harm.

I’m glad my machines at home are “dumb”. All my cleaner wants to take over is the carpet in my living room. Let’s hope they don’t create an appliance which wants to take over the world!

1.The author quoted Bill Gates’ words in Paragraph 2 in order to make the text ________.

A. better-knownB. more persuasive

C. better-organizedD. more interesting

2.An intelligent paperclip machine would harm us because ________.

A. it is much cleverer than us

B. it would take over the world

C. it would see us just as material

D. it has the strong feeling of destroying us

3.How does the author feel about Isaac Asimov’s rules of robotics?

A. OptimisticB. SympathyC. DisappointedD. Regretful

4.What does the text mainly focus on?

A. The benefits of future robots.

B. The new applications of robots.

C. The concern for super intelligence.

D. The popularity of robots in the future.

The English language is a result of the invasions of the island of Britain over many hundreds of years. The invaders lived along the northern coast of Europe.

1. The Angles were a German tribe who crossed the English Channel. Later two more groups crossed to Britain. They were the Saxons and the Jutes. Through many years, the Saxons, Angles and Jutes mixed their different languages. The result is what is called Anglo-Saxon or old English.

The next great invasion of Britain came from the far north beginning about l,100 years ago. People called Vikings came to the coastal areas of Britain. 2. Words like "sky" , "leg" , "skull" , "egg" , "lift" and "take" are from the old languages of the far northern countries.

The next invasion of Britain took place more than 900 years ago, in 1066. 3.William the Conqueror led it.

The Normans were a French-speaking people from Normandy in the north of France. They became the new rulers of Britain. These new rulers spoke only French for several hundred years. It was the most important language in the world at that time. 4. But the common people of Britain still spoke old English.

Old English took many words from the Norman French. Some of these include "damage", "prison" and "marriage". The French language used by the Norman rulers greatly changed the way English was spoken by 800 years ago. 5. Middle English sounds like modern English. But it is very difficult to understand now. The history of the English language continues as Middle English becomes Modern English, which is spoken today.

A. History experts call this invasion the Norman Conquest.

D. Therefore most common people speak the language.

E. Few people spoke Middle English at that time.

F. Many English words used today come from these ancient Vikings.

G. The first invasions were by a people called Angles about l,500 years ago.

Last winter, my classmates and I went to London to attending a winter camp. To better understand the history and culture of a city, we scheduled a “museum trip”. In Saturday morning we got up early and studied the map carefully to work out the route. One of my classmates suggested go there by bus to enjoy the street view. It was a long ride, so that we got off the double-decker bus, we seemed to lose way. The streets looked busy and strangely, and we have had to ask a passer-by for help. She pointed out the right direction and wished us a good day. Thanks to the friendly woman, we finally got to our destination. It took us some effort, however we witnessed the real beauty of the city. The experience also abled us to practise our English. What a terrific experience!

Usually, a wedding's main focus is on the bride and groom. However, one couple were upstaged by a huge brown bear that they invited to be a part of their special day.

Denis and Nelya, both 30, from Moscow, Russia, hired 21-stone Stepan to play the role of ringbearer — and he even turned up to their ceremony wearing a black bow tie.

The bear, which stands seven-foot tall, was very involved with the ceremony, even posing for photos with both bride and groom.

At one point he even acted as the registrar and joins paws with the couple as they professed their love for each other. Standing underneath a cream fabric canopy(華蓋) and surrounded by greenery, flowers and fruit, Stepan helped the couple on their wedding day.

Denis said, “We both knew Stepan is a very kind bear but still it is a huge, unpredictable animal so we were a bit scared, but still happy to be able to make our dream come true. It was a fantastic experience to have this photo shoot with Stepan. We will absolutely remember this day forever.”

Stepan the bear first found fame in May 2016, when a series of photos of the tame animal were published. He was adopted by Russian couple Svetlana and Yuriy Panteleenko aged just three months after being discovered by hunters in the forest, having lost his mother.

Svetlana said, “Stepan likes nothing more than to cuddle up with us on the sofa at night while we're watching television. He absolutely loves people and is a really sociable bear — despite what people might think, he is not aggressive at all. We have never been bitten by Stepan.”

1.The underlined word “upstage” in paragraph 1 probably means ________.

A. attractB. over-dropC. biteD. surprise

2.What do we know about Stepan?

A. Stepan is not happy at all at the wedding ceremony.

B. Stepan was discovered by Denis and Nelya.

C. Stepan is popular since he was born.

D. Stepan caught the guests’ attention.

3.Where might the passage be taken from?
