Artificial intelligence （AI， 人工智能） can help us make phone calls． It can guide us to where we want to go． It can play games． And now， AI can do even more things．
Researchers from Microsoft have created the first machine translation system that can translate news articles from Chinese to English， Business Standard reported．
According to Microsoft's official website， researchers tested the system by asking it to translate hundreds of sentences taken from news stories． Then， language experts compared the results to two translations that were done by humans． The experts said that the system's translations were as good as the human translations．
Machine translation is always challenging． This is partly because different words can be used to express the same meaning． It can be hard to say which word is more "correct"．
Experts used several methods to improve the system's translation abilities． "Much of our research is really learned from by how we humans do things，" lead researcher Liu Tieyan said．
One method is called dual learning （对偶学习）．In this method，the system translates every sentence from Chinese to English，as well as translates the sentences back from English into Chinese．This way，the system can improve itself and learn from its own mistakes． This is similar to what humans do to make sure their translations are exact．
Another method makes use of deliberation networks （推敲网络）．The researchers taught the system to repeat the process of translating the same sentence over and over．Gradually， the system can improve the quality of its translations． This is similar to how people correct their own writing by going through it again and again．

You either have it, or you don’t－a sense of direction. But why is it that some people could find their way across the Sahara without a map while others can lose themselves in the next street?
Scientists say we’re all born with a sense of direction, but it is not properly understood how it works. One theory is that people with a good sense of direction have simply worked harder at developing it. Research being carried out at Liverpool University supports this idea and suggests that if we don’t use it, we lose it.
“Children as young as seven have the ability to find their way around,” says Jim Martland, research director of the project. “However, if they are not allowed out alone or are taken everywhere by car, they never develop the skills.”
Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction. He makes the following suggestions:
If you are using a map, turn it so that it relates to(与……有联系) the way you are facing.
If you leave your bike in a strange place, put it near something like a big stone or a tree－something easy to recognize. Note landmarks on the route as you go away from your bike. When you return, go back along the same route.
Simplify(简化) the way for finding your direction by using lines such as streets in a town, streams, or wells in the countryside to guide you. Count your steps so that you know how far you have gone and note any landmarks such as towerblocks or hills which can help to find out where you are.
Now you will never get lost again!Children have the ability to find the way around when they are ______ years old.
| A．5 | B．6 | C．7 | D．8 |
Which of the following things cannot be used as landmarks?

| A．To give special importance to something. |
| B．To express thanks for somebody. |
| C．To understand or become aware of a fact. |
| D．To admire somebody. |
Scientists believe that __________.
| A．some babies are born with a sense of direction |
| B．people learn a sense of direction as they grow older |
| C．people never lose their sense of direction |
| D．everybody has a sense of direction from birth |
What may be the best title of the passage?
| A．A research on direction. |
| B．A sense of direction. |

(One day Alice runs after a strange rabbit and comes into a deep hole. She becomes smaller when she wakes up the next day. She finds herself in a wonderland with many amazing things inside.)
The Caterpillar(毛毛虫) and Alice looked at each other for some time in silence. At last the Caterpillar took the pipe out of its mouth, and said to her in a tired, sleepy voice.
“Who are YOU?” said the Caterpillar.
This opening for a talk couldn’t make Alice at ease. Alice replied, rather shyly, “I----I hardly know, sir, just at present ----at least I know who I was when I got up this morning, but I think I must have been changed several times since then.”
“What do you mean by that?” said the Caterpillar, “Explain yourself!”
“I can’t explain MYSELF. I’m afraid, sir.” said Alice, “because I’m not myself, you see.”
“I don’t see.” said the Caterpillar.
“I’m afraid I can’t put it more clearly.” Alice replied very politely, “for I can’t understand it myself. And being so many different sizes in a day is very puzzling.”
“It isn’t.” said the Caterpillar.
“Well, perhaps you haven’t found it so yet.” said Alice. “But when you have to turn into a chrysalis(蛹，茧)----you will some day, you know ----and then after that into a butterfly, I think you’ll feel it a little stranger, won’t you?”
“Not a bit.” said the Caterpillar.
“Well, perhaps your feelings may be different.” said Alice. “All I know is, it would make ME feel very strange.”
“You!” said the Caterpillar scornfully. “Who are YOU?” The question brought them back again to the beginning of the talk. Alice felt a little angry because the Caterpillar was making such VERY short sentences. She drew herself up and said very seriously, “I think you ought to tell me who YOU are first.”
“Why?” said the Caterpillar.
Here was another puzzling question. As Alice could not think out any good reason, and as the Caterpillar seemed to be very unpleasant, she turned away.
“Come back!” the Caterpillar called after her. “I’ve something important to tell you!”
This certainly gave Alice some hope. Alice turned and came back again.Where may their talk take place?
| A．In a wonderland. | B．In the field. |
| C．In the tree. | D．Outside the hole. |
Alice didn’t feel __________ during her talk with Caterpillar.
| A．shy | B．sad | C．angry | D．strange |

| B．“Don’t be angry. You think you’re changed, do you?” said the Caterpillar. |
| C．“Don’t be sad. You’ll grow bigger again.” said the Caterpillar. |
| D．“Don’t be afraid. You can go home now.” said the Caterpillar. |
Food waste has become a big problem in China.
Zhou Jinsong, a canteen(食堂) manager at Central South University, said that students produce over 12 barrels(桶) of leftovers every day — each barrel stands at one meter in height. Zhou’s canteen is just one of several on the campus.
According to Xinhua News Agency, the food wasted by Chinese people equates to about 50 million tons of grain every year, or 10 percent of the country’s total annual grain production. This food could feed another 200 million people. What students waste every year could feed over 10 million people. Students nowadays are well protected by their families and hardly know how hard farmers work to provide them with the food they eat.
“Since the 1980s, when Chinese gradually became richer, food waste has been a subject of debate. But things have hardly changed over the years,” said Yu Changjiang, a sociologist at Peking University. “It’s the Chinese way of showing respect to friends, often referred as Mianzi.”
But rather than tradition, huge public spending on government banquets(宴会) is also causing food waste, said Zhou Xiaozheng from the sociology department at Renmin University of China. “It’s the result of widespread reception meals at government levels. It is also important that everyone thinks about how they can do their best to reduce food waste.”Which of the following statements is not the reasons for food waste?
| A．Students hardly know farmers’ hard work on the farm. |
| B．The government spends a large amount of money on government banquets. |
| C．Leaving some food after a banquet is the Chinese way to show respect to guests. |
| D．The food in the college canteen is not delicious. |
Where can we probably read this passage?
| A．In a newspaper. | B．In a traffic report. |
| C．On a health website. | D．In a story book. |
