题目:

在指定文件夹下打开文档WTL.DOG,其内容如下:【文档开始】为什么铁在月球上不生锈众所周知,铁有一个致命的缺点:容易生锈,空气中的氧气会使坚硬的铁变成一堆松散的铁锈。为此科学家费了不少心思,一直在寻找让铁不生锈的方法。可是没想到,月亮给我们带了了曙光。月球探测器带回来的一系列月球铁粒样品,在地球上呆了好几年,却居然毫无氧化生锈的痕迹。这是怎么回事呢于是,科学家模拟月球实验环境做实验,并且进行X射线光谱分析,终于发现了其中的奥秘。原来月球缺乏地球外围的防护大气层,在受到太阳风冲击时,各种物质层的氧均被"掠夺"走了,长此以往,这些物质便对氧产生了"免疫性",以至它们来到地球以后也不会生锈。这件事使科学家得到启示:要是用人工离子流模拟太阳风,冲击金属表面,从而形成一层防氧化"铠甲",这样不就可以使地球上的铁像"月球铁"那样不生锈了吗【文档结束】

将正文各段文字("众所周知……不生锈了吗")设置为五号仿宋_GB2312;各段落左右各缩进0.6厘米,段后间距设置为12磅;各段落首字下沉2行、距正文0.1厘米。

幼儿园开学了,小(三)班的一名小朋友上课时不是坐不住,就是随便说话,乱动别的小朋友;午休时,别的小朋友都睡觉了,就他自己怎么也不去睡,非要去玩玩具,这样一来,别的小朋友也不想睡觉,也想去玩玩具。王老师看到这一情况后,就对所有小朋友说:“谁能先躺倒床上睡10分钟,谁就可以先玩玩具,谁今天中午不睡觉,下午谁就不能玩玩具。”这时,小朋友都迅速的跑道自己的床上安静的躺下了。

这是在幼儿园教学中经常遇见的问题,试结合行为主义学习理论对这位幼儿教师的做法进行分析。

For a commuter rushing to catch a train, a minute can mean the difference between dinner with the family and leftovers (剩饭) in the microwave. What most passengers don’t realize is that their minute is already there.

Every commuter train that departs from New York City — about 900 a day — leaves a minute later than scheduled. If the timetable says 8:14, the train will actually leave at 8:15. In other words, if you think you have only a minute to get that train — well, relax. You have two.

The courtesy (礼貌) minute, in place for decades and published only in private timetables for employees, is meant as a grace period(宽限期)for those who need the extra time to get off the platform and onto the train.

“If everyone knows they get an extra minute, they’re going to waste time doing unimportant things,” explained Marjorie Anders, a spokeswoman for the Metro-North Railroad. Told of this article, Ms. Anders laughed. “Dont blow our cover!” she said.

Entirely hidden from the riding public, the secret minute is an odd departure from the railroad culture of down-to-the-second accuracy. The railroad industry helped invent the concept of standard time, and time zones were established in the United States in the 1880s, 35 years before they were written into law. And most commuters know their train by the precise minute it departs. The trains quickly make up the minute: at all other stops, the public timetable prevails. The phantom minute does not exist at commuter railroads in Chicago, Los Angeles, Philadelphia, or San Francisco. But in New York, the secret minute dates back decades.

“That’s been done forever, from my knowledge,” said Jack Swanberg, 70, an unofficial historian of Metro-North. “I was the trainmaster starting in 1970 and I’m sure it’s been the case since 1870 for all I know.”

小题1:The courtesy minute was hidden from the public to _____.

A.prevent the passengers’ idleness

A.Don’t publish the timetable

B.Don’t blame commuter trains

C.Don’t make it known by the public

D.Don’t forget our chances of catching trains小题3:What can we conclude from the passage?

A.The courtesy minute exists in many cities in the US.

B.One minute means a lot for most of the commuters.

C.The courtesy minute has been in place for about ten years.

D.Most railroad staff in New York have no idea of the courtesy minute.小题4: The passage mainly talks about _____.

A.the railroads in the US

B.the secret New York minute
