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 concluded 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 inspired (得到启发) by how we humans do things,” lead researcher Liu Tieyan said.One method is called dual learning. 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 accurate (准确的).
Another method makes use of deliberation networks. 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 revise their own writing by going through it again and again.

The way we spend our time can be divided into three groups or jars (罐子). These would be the necessary tasks jar, the voluntary tasks jar and the happiness jar.
Every day, we spend time filling the necessary tasks jar. We fill this jar with useful things, like making money, doing housework, buying food and paying bills. We then fill another jar with voluntary tasks. These are things that we do for others, but we may not enjoy them. This jar is filled with tasks like taking children to activities and cooking family meals. Those jars are very important. If we don’t fill them each day, our family won’t run properly.
However, we often forget to fill the third jar? the happiness jar. This is the jar that we fill with activities that make us happy. Is your happiness jar sometimes empty at the end of the day? We all have days like that. Between doing all the necessary and voluntary tasks, time flies by on some days, and before we know it, it is time for bed.
That is why each day we try to fill our happiness jar. Most days, I fill mine by going to the ballroom dance (社交舞) class. Between the music, the dancing and the friendship among the students, I always leave classes happier than when I entered. Playing music is another way that I fill my happiness jar. This week, I was happy to take part in an orchestra (管弦乐队) practice at my church (教堂). A small group of us met to practice Christmas music for a church service. It was a time of fun, friendship and music making. At the end of the evening, my happiness jar was full.
Consider how your time is spent. Try to find ways to achieve a balance. At the end of the day, hopefully we’ve done all we can to make sure that our happiness jar is filled.
1.How many kinds of jars are mentioned in this passage?
______________________________________________
2.What will happen if we don’t fill the necessary tasks jar and the voluntary tasks jar?
______________________________________________
3.Why do we often forget to fill the third jar?
______________________________________________
4.How does the writer fill her happiness jar?
______________________________________________
5.Do you think it important to fill the happiness jar? Why or why not?
