Machine Translation and Human Translation
In recent years, all kinds of electronic dictionaries and translation software have been developed. With the development of technology,these electronic dictionaries and software translate not only words even sentences and paragraphs. So some people come to the conclusion that machine translation will replace traditional human translation. However,I couldn't agree with this argument.
Admittedly,translation machines and software bring much convenience for our study and work. With them,we needn't bother to live through the heavy dictionaries. However,machine translation has its disadvantages. First,generally speaking, translation software direct translation, which is sometimes not in accordance with the original articles in logic and meaning. Second,some people depend on electronic dictionaries and software too much, which is unfavorable to their improvement in language ability.
Considering the above mentioned, I think that machine translation cannot replace human translation, but it is a good complementary to human translation. Therefore,we should combine machine translation with human translation effectively.
