That will be difficult: translation software must be trained with a lot of parallel text that has already been translated by humans.

翻译软件必须通过大量已经被人类翻译过的平行文本进行训练。

Besides manual input of vocabulary list, the new machine translation software can learn through the comparison of parallel texts -two texts about the same topic but in two different languages.

除了人工输入词汇表，新的机器翻译软件还可以通过平行文本的比较学习，即两个关于相同主题，但两种不同语言的文本。
