Top 2. Because the language doesn't have the common sense to use an alphabet.
The English is so easy because of the skills needed to master the writing system are 26 letters and they are written from left to right ,horizontally, across the page, with spaces to indicate word boundaries. In comparison, Chinese has nothing that corresponds to an alphabet, though there are recurring components that make up the characters. It can be said that the components of Chinese characters are arrayed in two dimensions, rather than in the neat one-dimensional rows of alphabetic writing.

原因二：汉语是不能用通俗意义上的字母排列来表意的。
英语之所以好学，就是因为掌握英语书写方法所需要的技能也就是26个字母而已，而且只要沿水平方向、从左到右、从页面的一边写到另一边就可以了。相比之下，尽管中文也有组成汉字的那些共用的偏旁部首，却没有相应的字母。可以说，组成汉字的偏旁部首是按照两个方向来排列的，而不象字母那样只按一个方向排列，看起来很整洁。
