 --- Isn’t that Ann’s husband over there ?

--- No, it _______ be him--- I’m sure he doesn’t wear glasses.

A.can’t            B. must not         C.won’t           D.may not

 

【答案】

A

【解析】

试题分析:考察情态动词用法。Can’t不可能;must not千万不能,禁止;won’t不会;may not也许不;句意:—那边的那个是Ann的丈夫吗?—不,不可能是他。我确信他不带眼镜的。Can’t是有把握的否定推测。根据句意说明A正确。

考点:考察情态动词用法

点评:英语中有不少情态动词都可以表示推测,其语气有强有弱,表示的可能性有大有小,现将它们的用法归纳如下:1. 接近100%的可能,只有must才具有这么高的可能性,它的意思是“一定”“肯定”,所作出的推测几乎接近事实。如:He must be coming by bus. 他一定是乘公共汽车来。2. 很有可能,表示可能性较大的情态动词主要有may, should, ought to,它们大致相当于汉语的“可能”“应该”“按理会”。 3. 一般性的可能,在所有表示推测的情态动词中,might和could所表示的可能性最小,由于它们的语气较委婉,较不确定,所以往往相当于汉语的“可能”“也许”“说不定”等。4. 理论上的可能性,表示理论上的可能通常是用can,且可以用于肯定句中。

In this modern world, we rush around all day, doing things, talking, sending and reading messages. We are always on, always connected, always thinking, always talking. There is no 36 for stillness.
And when we are 37 to be still because we’re in line for something, or waiting at a doctor’s appointment, or on a bus or train, we often  38 something to do. Some will play with mobile devices, other will read something. Being still isn’t something we’re 39.
This comes at a   40 : we lose that time for  41 , for observing and listening. We lose peace.
And   42 yet: sometimes too much action is worse than no action at all. You can run around crazily, but get  43 done.
Take a moment to think about  44 you spend your days. Are you constantly rushing around? Are you constantly reading and answering  45 checking on the news and the latest stream of information? Are you always  46 through your schedule?
Is this how you want to spend your  47 ? If so, peace be with you. If not, take a moment to be   48 . Don’t think about what you have to do, or what you’ve done already.   49 be in the moment.
Then after a minute or two of doing that, consider your life, and how you’d  50 it to be. See your life with less move anent, less doing, less rushing. See it with more stillness, more consideration, more  51 .
Then be that vision.
It’s pretty simple: all you have to do is sit still for a little bit each day.   52 you’re gotten used to that, try doing less each day. Breathe when you feel yourself moving too  53 . slow down. Be present. Find happiness now, in this moment, instead of   54 for it.
