     You are not given false information first that sounds as if it could be the answer to the question. An
instance(例证) of this may be that the information given matches one of the answers, but does not meet
the criterion(标准) given in the question-the person could be talking about last week when the question
asks about next week. The correct information usually, if not always, comes afterwards.
      Nearly right is not the same thing as right; examinations often give information that sounds more or
less correct, but is in some way unsatisfactory. Adverbs and modals(情态动词) are often used to send
you the wrong way; the listening text might use “ She may well be late” - and the question “ She will be
late” this is not an exact match and consequently(结果) could easily be the wrong answer. It has to be
________.
     In longer listening passages, they often try to lend you to lose concentration by having quite long
sections where no information relevant(有关的) to the exercise is given. But then out of the blue
(unexpectedly) they hit you with a couple of answers in quick turns.
     Although most longer listening passages begin with an introduction that lets you get into the flow
before they start testing you, you can not depend on this; the first word could in theory(理论) be the
answer to the first question.
     Examiners will often place a word directly from the passage in a wrong answer and use a synonym
(同义词) in the correct answer. Check the meaning and do not rely on word recognition to get the right
answer.
