☆TOEFL, TOEIC AND English Ability of Japanese☆

I read this book(TOEFL, TOEIC AND English Ability of Japanese), and I am interested in this book very much!! This author said many interesting and good opinions. I could learn much from the book.

First, this author said "the score of these tests can't show a person's all English ability". She said it was impossible to guess our all ability by these tests!! I was interested in this opinion, because I think we tend to think that "high-score means high-ability."Actually I tend to think the person who got high-score in TOEFL test could speak English fluently, could write English sentences well, and so on. But the author said sometimes it is not right.

Second, this author said "it is the most important to have purposes when we challenge these tests."And she also said "these tests should be used for testing the result of own English study." I think it is an interesting idea. Because, I think, There are lots of people challenge these tests for qualifications or getting some good jobs. In these cases, getting high-score is their purpose.
But the author said it is an strange thinking. She said, first we should have a purpose, next we should study for the purpose, and lastly we can check our effort by these tests. I think it is a good thinking!!
