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.

2.What did the experts say about the system's translations?

3.Dual learning trains the system to translate _____.

C.more accurately D.the same sentence repeatedly
4.What is the main idea of the story?
