请熟悉以下一些字句，不要因搞不清意思而答错问题
must usually certainly can/may only absolutely essential
can should necessary to need to should not (shouldn't)
will won't unnecessary to need not (needn't) it is optional
may might have to sometimes it is possible
yet always cannot (can't) not required to strictly prohibited
never could often ought to don't have to
but however an exception is on the other hand must not (mustn't)
有时候，您认为最有把握听得出来的答案往往有错。如您不小心听清楚的话，只差一两个字意思便会刚刚相反，有时候，讲者讲出来的跟答案完全一样，但要是您不留心还是会出错，请看以下例子：
问题：The Macintosh computer network can only be used A I N by second and third year students.
声带内容：“The Macintosh computer network is reserved for second and third year students only ...” 考生听到这里为止会认为答案是对的，但句子的后部是：“... unless you are a first year student of the Graphic Design course.”因此作答时要小心，不要分神。
