For people, it's not surprising that we can open a door, lift a heavy box and control ourselves while walking in the snow. But can a robot do this? Well, Google's new robot, Atlas, can not only do these things, but it can also stand up if it falls down. Although the robot may be slow and clumsy, it was created mainly to work in dangerous places for humans.

Now, robots are much smarter than you might imagine. On March 9 this year, AlphaGo, an artificial intelligence (AI, 人工智能) program made by Google's DeepMind, challenged top professional Go player Lee Se­dol from South Korea. And AlphaGo beat Lee at last.

AI is when computers or computer software is able to have intelligent behavior, such as thinking or acting like a human. In our daily lives, we already use AI in many ways, like Apple's Siri and search engines like Baidu and Google.

Some people may worry whether computers are now smart enough to beat us at everything. But experts say that is not the case. Real life problems can be more difficult than the Go game. For example, humans can watch a person throw down a cup of coffee and know that the result will be a mess on the floor. A computer program would have to know the size of the cup, the height of the cup from the floor and many other things to find out the result. But we never know what will happen in the future.

Cats and dogs are the most popular pets in America. So it is not surprising that we can find different sentences (句子)about cats in a language book when we learn English.

Unlike dogs, it is difficult to teach cats to do something. Cats are not like sheep or cows that can be moved in a group. So we say a difficult or impossible job is like “herding(放牧) cats”.

Everybody knows cats and mice are “good friends”. Sometimes, a cat likes to play with a small animal it catches, such as a mouse. So if your daughter offers something sweet to her little brother and then takes it away when he reaches for it, you can use "play cat and mouse". What will children do in a classroom when their teacher leaves for a few minutes? They are sure to make as much noise as possible."When the cat's away, the mice will play" has the same meaning.

There are a lot more sayings about cats. Americans might say "the cat's miaow" to describe（描述） something that is the best or finest. “A fat car" means a person with lo of money. If you tell about something secret（秘密）, we say you “let the cat out of the bag”. If you are not able to speak or answer a question, someone might think 'the cat has got your tongue(舌头)". Also, you may often hear the sentence “Curiosity(好奇) killed the cat.” That means caring too much about things that are not your business(与你无关之事) might lead to serious problems.

1.What may you say if you want someone to keep the secret for you?

A. Curiosity killed the cat. B. Has the cat got your tongue.

C. Don’t let the cat out of the bag. D. Let’s play cat and mouse.

2.Which of the following can we use “Curiosity killed the cat” to describe?

A. Someone always asked a lady her age or weight and it made her angry.

B. Someone made a big noise as soon as the teacher left the classroom.

C. Someone won the first in the final test and he felt very excited.

D. Someone got the newest iPhone as a present from his parents.

3.What can we learn from the article?

A. We can use “A fat cat” to describe a fat man or a person who eats too much.

B. There are more sentences about cats than those about dogs.

C. It’s more difficult to keep sheep or cows than cats.

D. “Play cat and mouse” usually means “play tricks on sb”.

4.Where can you find the article?

A. In a science report about cats.

B. On a website telling people how to keep cats.

C. In a magazine telling different jokes and funny stories.

D. In a language book that teaches students how to use saying about cats.
