【答案与解析】 数字秒表可能会产生高达0.11秒的舍入误差，这足以改变势 均力敌的比赛的结果。尽管设备记录时间非常准确，但它们在将 原始数据转换为人类可读值时经常出错。 21.A 根据第2段最后一句可知，浮点表示法广泛应用于数码设备。 22.D根据第3段第1、2句可知，数字秒表的误差是在浮点表示 法的数据转换成秒表显示屏可见的数字时发生的。 23.C根据第4段画线词所在句与上一句的转折关系可知，当被 记录的时间用类似于秒表显示屏显示数字的算法传递时，他们 又看到了（第3段提到的）不精确的数字。 24.D根据倒数第2段第1句可知，为了避免秒表的舍入误差， Faux建议将石英晶振的次数直接用更大的秒表显示屏显示，而 非用算法来转换摆动次数。

the screens of stopwatches,they once again saw a skewed num ber. Faux says that the obvious solution is for stopwatches to have large data tables for transforming the numbers of oscilla- tions into the time in seconds,rather than using an algorithm. The researchers now hope to investigate whether the errors are found at large sporting events. New Scientist asked the International Olympic Committee if timing at the Olympic Games could be affected by this phenome non.The IOC passed the request for comment to Omega,the of- ficial timekeeper of the Games,which didn't respond.

第二部分阅读理解（共4小题；每小题7.5分，满分30分） 阅读下面短文，从每题所给的A、B、C和D四个选项中，选出 最佳选项。 Digital stopwatches can make rounding(四舍五入的) errors of up to 0.11 seconds,which could be enough to change the win ner of close races.Although the devices record time extremely accurately,they often make errors when changing that raw data to human-readable numbers. Most digital stopwatches measure time by counting the pre- dictable oscillations (of a quartz crystal.The crystal will pulse many thousands of times a second and the final count is transformed into seconds in a format known as a floating-point representation that is commonly used by digital devices.

good introduction to the course,and it will probably cover a lot of useful information about the upcoming semester. W:Maybe you're right.It's just that I hate being in large groups.I'm not going to know anyone there. M:You'll know me,though.Besides,I think it will be a good chance to meet people,and there will probably be times when we will have to work together in groups. W:Our course outline seems to have all the information we need. I can't see there is anything new to discuss. M:I heard there will be a former graduate there to provide details about what kind of job opportunities are out there after we graduate.It could be more helpful than you think. W:I don't know.

W:Well,I've got something quite different from that this time. No singing at all.Though it's got some great music,it's an adventure in space.I'm sure you'll enjoy that more than a comedy we saw last time. M:Great!Let's watch that then. (Text 7) W:Happy New Year！ M:Happy New Year!Kate,do you have any wishes for the new year? W:Of course.I hope I can get a good score in the college en- trance examination in June this year,and I can visit Beijing during the summer holiday. M:Which is the most important?

解析：区域发展过程中，产业结构一般经历第一产业、第二产 业、第三产业→第二产业、第一产业、第三产业→第二产业、第三产 业、第一产业的过程，就业结构也将逐渐实现这个过程。因此就业 结构的变化顺序应为由以第一产业为主转变为以第二、三产业为 主，并且第三产业超过第二产业，顺序应为③④②①。 答案：B

老二说：“大哥，您是不是想请人挖掘一下，宣传我们袁家的祖 先？” 老三说：“拍成电影，咱袁桥火了，咱袁家也就一下子出名了。” “当年咱的祖先是为了名声吗？”大哥说罢，长出一口气，似乎 有点失望。 “大哥，您的意思—”老二疑惑地问道。老三的眼睛里也藏 满了问号。 大哥答非所问，继续说道：“清咸丰年间，太平天国运动爆发， 登封县境内乱军滋扰，为保护乡民，袁家十六世袁梦松出资修建了 土寨墙。抗日战争时期，为躲避日伪军的骚扰和破坏，登封第一次 党代会就是在袁家十九世袁毅家召开的…” 老二终于忍不住了，说：“大哥，您越扯越远了。您究竞要干 啥？直说嘛。只要决策正确，我和老三都不会拦您。” “大哥，您是不是有什么难处？常言道：‘上阵父子兵，打虎亲 兄弟。’有我和二哥，怕什么？！”老三附和道。
