雅思流程图作文的四项注意点

　　流程图写好的第二个关键是被动语态的使用。流程图表现的是客观的工作流程或事物发展的过程。因此，我们可以尽量避免用We should/must/need to do sth.的主动语态，改为Sth.Should/must/needs to be done这样的被动语态。被动语态和情态动词的恰当搭配，可以使文章显得更具有客观、和学术化色彩。

　　The production of cement starts in a mixer， where limestone gravel and sand are convertedinto a mixture， which is then fed into a crusher. Here the mixture is ground into cement powder， and then is passed through a rotating heater.
