题目内容

8.There's no way of knowing why one man makes an important discovery _____ another man,also intelligent,fails.(  )
A.sinceB.ifC.asD.while

分析 句意为:不清楚为什么一个人会有重大发现,而另外一个同样聪明的人却失败了.

解答 答案:D 本题考查从属连词和并列连词的区别.根据句意断定,该题的空格处需要填入一个并列连词.乍一看,这四个连词似乎都是从属连词,都不能填入句中.殊不知,在实际的语言运用过程中,while还具有并列连词的属性,表示"转折和对比",正好符合句式结构和语意逻辑.故答案选D.其他三个选项都没有这种属性和功能,所以可以排除.

点评 考查并列连词时,要注意区分和从属连词的区别.

Ways to save time

We all wish we had just a bit more time. Just think what you could do with an extra hour or two each day: you could finally stick to an exercise routine, or spring-clean the house, or write your novel, or learn the guitar and so on.

1.But I can help you find more hours in your day for the things that really matter.

★Get Out of Bed Earlier.

If you normally get up at 7:30 a.m. try getting up at 7:00 a.m. That half-hour might not sound like much, but it could be time that you use to exercise, to read that book you've been meaning to finish.2.

★Do the Important Tasks First.

Once you get to work, get the important ones done first (not the easy ones, or even the urgent ones). 3.If you work like this, you’ll usually save time. The urgent tasks will still get done, and you won't miss the important ones.

★Reduce Interruptions.

If colleagues have a habit of hanging around your desk to chat, or if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter.4.

5.

A few minutes chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day. If your concentration is slipping, take a proper break: go and get a glass of water, or stretch your legs a bit. And if you’re facing a difficult task, try breaking it into small steps or stages so that it’s easier to deal with.

A. Stay Focused on Your Work.

B. Take Breaks When Necessary.

C. Would you want me to make your day longer?

D. I can’t magically make all your days 25 hours long.

E. Or simply to get your day off to a calm and organized start.

F. Constant interruptions don’t just eat up time, they also break your concentration.

G. You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones.
