和大学六级相当，不过还是有区别的 首先从听力上说,专四比六级多了一个听写部分,占15分,这个部分,如果你听力好的话是个送分的项目,但如果你听力不好的话这就会是个要命的题.另外,专四听力部分的coversation,passage,news三个部分的题量是30题,比六级的题量要大,而且多了新闻,但是我个人认为专四的passage和conversation部分比六级要简单多了. 然后是词汇,六级的话词汇量稍微大些,但专四考的词汇一般是比较生僻的词意. 接首是阅读部分,这个的话,六级的阅读偏理一些,科普之类的文章多,但是专四的话他的阅读就偏文,科普之类的文章很难遇到. 最后是写作部分,专四有两篇,一篇大作文,一篇便条.六级只有一篇 从大的来说,专四考试的时间相对于六级来说要紧些,题量也大些.
