Researchers from Microsoft have created the first machine translation system that can translate news articles from Chinese to English.

The researchers tested the system by asking it to translate hundreds of sentences taken from news stories. Then, language experts compared the results to the translation that were done by humans. The experts said that the system's translations were as good as the human translations.

Experts used several methods to improve the system's translation abilities. “Much of our research is really learned from 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(质量) of its translations. This is similar to how people correct their own writing by going through it again and again.

七、阅读填空 先通读下面的短文,然后根据短文内容,在文章后表格的空格内填入一个最恰当的单词。所填单词必须写在答题卷对应题号的横线上。每个空格只能填一个单词。

When a disaster happens, you might find yourself without water, gas and electricity. You might even need to leave your home with little warning. But disasters don’t have to surprise you. Plan before something bad happens.

Hold a family meeting. Discuss the types of disasters that could happen. Then plan a way to make your family be with each other if they get away. Choose two places for everyone to go to if it isn’t safe to return home. The first should be near your house. You can go there in a very dangerous situation like a fire. The second meeting place should be outside your neighborhood. This will give your family a place to come together if you must evacuate(疏散撤离).

Next, choose a contact (联络) person outside your area. After a disaster, it is often easier to exchange information or talk with other people over a long-distance call than a local one. A contact person can pass messages between family members if they can’t meet or get in touch with each other.

Then create a family disaster work-box. It should include everything your family needs to survive for at least three days. Place your tools in a bag, so you can carry it if you need to evacuate. When getting ready for it, remember that different people have different needs, including special items necessary for not only elderly but young members of your family.
