this和that都可代表前面提到过的事情,若出现两个名词,指代前面的用that指代较后面的用this;但若指下文将要叙述事情,则只能用this，不能用that。此外，还可用于代替上文中出现过个单数或不可数名词，且后面带有of短语修饰。Health is above wealth; this cannot give so much happiness as that.健康胜于财富;财富不会像健康那样带来那么多幸福(句中this=wealth;that=health)They cant afford it.That/this is their problem.What I want you to remember is this :English is of great use.(此句中this不能用that替换)The popula tion of Shanghai is larger than that of Suzhou. 而你给出的考题中，Partly that reflects the greater specialization~~~~这个句子仍然是与上文a few of the procedures or methods相关所要陈述的内容。这就运用了：若指下文将要叙述事情,则只能用this，不能用that。
this 在这里指代前文中说的“Even with a training "form" of degree, only a few of the procedures or methods practiced in your studies are likely to be continuously relevant in your work”的整个内容哦。this 和 that 的主要区别就是离说话者远近的问题，所指代的内容刚刚说过，并且是作者说的，作者为说话者，我们为听众，所以从作者的角度来看应该是this ，希望你能明白。
