Topic: Writing only the body part of the letter to the parents of your student to persuade them to establish a class library.

Whole-person education can largely be realized through exploring many books. Unlike the traditional concept of education, we are now devoted to delivering whole-person education that fosters spiritual, intellectual, humane, social and physical development of our students. There center lies experience, with its effect intact even it is indirect one. All of the indirect experience from books enables students to develop creativity through envisioning the written text, acquire necessary knowledge, establish a sound set of values and there is much more left. All these positive results contribute to whole-person education which is why a library is necessary for our class.
Setting up a class library also helps improve reading related skills that are a must for our students to take the college entrance exam in a few years. The items in the exam require students first to understand the question and then figure out the answer that best suits to the question. The ability to understand the question and figure out the key point stems from abundant exposure to written texts. Students will benefit much if they are to be exposed to the reading materials in classroom where they can spare effort to find books.
