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.

波波熊暑假作业江西人民出版社系列答案Every time we turn on the TV or take a ride in a car, we could be adding to a problem called acid rain(酸雨). In this article, we’ll learn something important about acid rain.
The formation of acid rain
When people use fuels (燃料), such as coal and gasoline(汽油), poisonous gases are given off. When these gases come together with rain, acid rain forms. Many power stations burn fuels in order to create the electricity(电) that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they burn gasoline. When rain meets these gases, harmful things called acids form. This is acid rain.
The harm of acid rain
Acid rain destroys everything that it touches. It poisons our rivers, ponds and lakes and oceans along with the life in them. It pollutes our soils and crops, harm trees, and can even kill fish and plants. Acid rain also eats away at our buildings.
The prevention of acid rain
We need to reduce and even stop the pollution that gets into our air. Turn off lights, televisions and other electrical appliances(电器) if we are not using them. Walk and take a bike whenever possible. If we are travelling a long distance, take a bus or train to save fuel.
As research shows, acid rain harms our environment. But people everywhere can take small steps now to help protect our environment for future generations.
Whenever we use electricity or drive our cars we may add something bad to the air around us. And even worse, we may cause a terrible problem—acid rain. | |
