some people think machine translation is highly develpoed in today's society.therefore it is not necessary for students to learn a foregin language.

With the rapid development of computer science，Computer can help people do lot of thing。Especially with the advent of deep learning, neural networks and other technologies, we seem to see that it is possible to make machines intelligent. 2016 Li Shishi vs. AlphaGo。some people raise doubts about AI（artificial intelligence） is omnipotent.

1.machine translation is a helpful tool in one‘s study。

At first thought.it seems that the computers can really help us do everythin。in one‘s study，machine translation is helpful，When learning a foreign language, the most difficult thing is to remember the words, but this is very simple for a machine, we can use the machine to help us remember the words.It can also correct spelling mistakes.so it is useful。
