Dear editor, I am Paul , a senior English teacher in Linchuan No. 1 Middle School in Jiang

Dear editor,
I am Paul , a senior English teacher in Linchuan No. 1 Middle School in Jiangxi Province , China. This letter is written to ask for your opinion.
The other day, I met with a multiple - choice exercise. We teachers argued heatedly with each other over its answer. Unfortunately, neither side could convince the other. The sentence is to be attached at the end of the letter. There is no doubt that the reference answer C is correct. But I don’t  think it is the only answer. Personally, I do think A is also a reasonable choice in sense as well as in grammar, if the case is treated from another aspect.                                
What puzzles me is why we should deal with so many multiple - choice exercises with not rigorous（严谨的）enough reference keys. But being a teacher, it’s very important and necessary to make it clear to students which answer is correct, which is more appropriate, and which is the best one. Regrettably, Multiple - choice test, which is a bit old - fashioned in western countries, seems to be quite popular and covers a rather high percentage in all sorts of English tests in China, especially in NMET.
Personally speaking, I don’t think multiple - choice test form making up more than 75 percent of the total scores in college entrance examination is a very good and effective testing method. Instead, more subjective testing forms depending on one’s own thinking and his ability to use the language like key words falling, question answering, paragraph or passage summarizing, English - Chinese or Chinese - English inter - translation, etc. should be applied to English proficiency tests. Through the test forms mentioned above, students’ ability to use the language will be better developed. Consequently, more advanced and outstanding English learners could be picked out. In fact, a test paper focusing on multiple - choice test influences, in a sense, students to form their own language thinking, which hinders（阻碍）the development of their language ability as well. Do you think so?
I am looking forward to your authoritative opinion. Thanks.
Yours sincerely,
Paul Liao
