A.五十万分之一

B.1∶1500000

C.1∶3500000

D.三百万分之一

答案

答案:A

本题考查对比例尺大小的掌握情况。比例尺有三种表示方式,在解答此类问题时,如果我们把每个选项所给的比例尺都变为数字式,即变为分式,再来比较它们的大小就显得容易多了。因为这四个分式的分子均为1,分母愈大,分式的值就愈小;反之,分母愈小,分式的值就愈大。  A.五十万分之一,可变为1/500000    B.1∶1500000,可变为1/1500000

C.1∶3500000,可变为1/3500000     D.三百万分之一,可变为1/3000000显而易见,四个分式中,A的分母最小,其分式的值(即比例尺)也最大。

As you are probably aware, the latest job markets news isn’t good: Unemployment is still more than 9 percent, and new job growth has fallen close to zero. That’s bad for the economy, of course. And it may be especially discouraging if you happen to be looking for a job or hoping to change careers right now. But it actually shouldn’t matter to you nearly as much as you think.

That’s because job growth numbers don’t matter to job hunters as much as job turnover(人员更替) data. After all, existing jobs open up every day due to promotions, resignations, terminations(解雇), and retirements. (Yes, people are retiring even in this economy.) In both good times and bad, turnover creates more openings than economic growth does. Even in June of 2007, when the economy was still moving ahead, job growth was only 132,000, while turnover was 4.7 million!

And as it turns out, even today — with job growth near zero — over 4 million job hunters are being hired every month.

I don’t mean to imply that overall job growth doesn’t have an impact on one’s ability to land a job. It’s true that if total employment were higher, it would mean more jobs for all of us to choose from (and compete for). And it’s true that there are currently more people applying for each available job opening, regardless of whether it’s a new one or not.

But what often distinguishes those who land jobs from those who don’t is their ability to stay motivated. They’re willing to do the hard work of identifying their valuable skills; be creative about where and how to look; learn how to present themselves to potential employers; and keep going, even after repeated rejections. The Bureau of Labor Statistics data shows that 2.7 million people who wanted and were available for work hadn’t looked within the last four weeks and were no longer even classified as unemployed.

So don’t let the headlines fool you into giving up. Four million people get hired every month in the U.S. You can be one of them.
