  • 第1题:

    There was a profound silence after his remark.

    A:short
    B:deep
    C:proud
    D:sudden

    答案:B
    解析:
    本句意思:他讲完后紧接着的是一阵意味深长的沉默。profound“意义深远的”,与deep 意思相近。short“短暂的”;proud“骄傲的”;sudden“突然的”。

  • 第2题:

    There is a real possibility that these animals could be frightened,( )a sudden loud noise.

    A.being there
    B.should there be
    C.there was
    D.there having been

    答案:B
    解析:
    考查虚拟语气。句中that引导的从句these animals could be frightened,a sudden loud noise是possibility的同位语,其中包括一个表示与将来事实相反的虚拟语气句,条件从句中没有if,应用部分倒装,将助动词should移至句首。故本题选B。句意:万一突然有巨响,这些动物 就会受到惊吓,这确实 是可能的。

  • 第13题:

    Life gets noisier every day and very few people can free from noise of some sort or another.It doesn′t matter where you live--in the middle of a modem city,or a faraway village--the chances that you will be disturbed by jet aero planes,transistor radios,oil powered engines,etc.,are almost everywhere.We seem to be getting used to noise,too.Some people feel quite lonely without background music while they are working.
    Scientific tests have shown that total silence can be very frightening experience for human beings.However,some people enjoy listening to pop music which is very loud,and this can do harm to their eardrums(耳鼓).The noise level in some disco is far above the usual safety level for heavy industrial areas.
    One recent report about noise and concentration(专心)suggested that although a lot of people say that any noise disturbs their concentration,what really affects their ability to concentrate is a change in the level of noise.It goes on to say that a background noise,which doesn′t change too much(music,for example)may even help people to concentrate.

    "Background music"in the passage means

    A.music played in the concert
    B.a kind of noise coming into your ears
    C.music which helps people to concentrate
    D.music played while people are working

    答案:D
    解析:
    考情点拨:词义猜测题。应试指导:从第一段最后一句可知,background music是人们工作时听的音乐。
