To persevere means victory!
坚持就是胜利!
To see once is better than to hear a hundred times.
百闻不如一见。
但在很多情况下,特别是在口语中,我们常常用代词it来代替它作主语,而把它移到句子后部去,这样使句子显得比较平稳:
It is not an easy thing to master a language.
学好一种语言是不容易的。
It only took (us) a year to complete the project.
完成这项工程只花了(我们)一年时间。
如果要说明不定式表示的动作是谁做的,可以在不定式前加一个for引起的短语:
It is not hard for one to do a bit of good.
一个人做点好事并不难。
It will be a mistake for us not to help them.
我们不帮助他们是错误的。
