Last but not least, computer programs are designed and written by human beings. People can’t design an efficient translation programs if they do not know the knowledge of foreign languages and translation.
Admittedly ,in some case, computer takes some advantages to us. Some translation computer programs can give us an immediate explanation of some difficult words when we read some foreign articles. It can save us a lot of time.
In conclusion ,from my point of view, it is still necessary to learn foreign languages. For the existing computer technology, computer can’t replace the process of language study.
