Is it right?

Re: Is it right?
"Next week we will have an exam (examination) in listening to English. Some of it is in our textbook. So we have begun to read and memorize it. I do not think it is right. But what should we do?"

You should follow the lesson plan, for two very good reasons. The first is that your performance will be evaluated on that basis, whether or not you think it is "right."

The second is more subtle, and something which apparently has not occured to you. English is a lnaguage which is radically different than Chinese. It is not inflected as Chinese is, and instead, relies upon differences in the spelling and pronunciation of words to indicated time and reference. For example, you wrote "memory" instead of memorize. You cannot change the noun memory into the verb memorize by inflection, you need to alter the spelling and pronunciation. Having you read and memorize texts in English before you listen to the spoken word will aid you in recognizing the differences in pronunciation which arise from differences in spelling. This is a standard method in the teaching of English as a second language, and is far more crucial in teaching English to speakers of inflected langauges, such as Mandarin, than it is in teaching English to speakers of, for example, Romance languages.

Follow the program, whether or not you think it is "right." There is a good reason for this method, and even if it is not necessary to you, your performance will not hinge upon whether or not you think it is right--it will depend upon your cooperation with the program.
