谁会这道题:阅读理解.  A
  About 21,000 young people in 17 American states do not attend classes in school buildings.  Instead,they receive their elementary and high school education by working at home on computers.The center for Education Reform says the United States has 67 public “cyberschools(网络学校)” and that is about twice as many as two years ago.  The money for students to go to a cyberschool comes from the governments of the states where they live.Some educators say cyberschools receive money that should support traditional public schools.They also say it is difficult to know if students are learning well.  Other educators praise this new form of education for letting students work at their own speed.These people say cyberschools help student
s who were unhappy or unsuccessful in traditional schools.They say learning at home by computer ends long bus rides for children who live far from school.  Whatever the judgment of cyberschools,they are getting more and more popular.For example,a new cyberschools called Commonwealth Connections Academy will take in students this fall.It will serve children in the state of Pennsylvania from ages five through thirteen.  Children get free equipment for their online education.This includes a computer,a printer,books and technical services.Parents and students talk with teachers by telephone or by sending emails through their computers when necessary.  Students at cyberschools usually do not know one another.But 56 such students finished studies at Western Pennsylvania Cyber Charter School recently met for the first time.They were guests of honor at their graduation.

不少大人都算不出“标准答案”,引发质疑。中新网5月11日电 据外媒报道,近日,外国一份小学二年级的数学题在社交网络上引起网友的热议,不少大人都算不出“标准答案”,引发质疑。这道题的题目很简单:一架载客火上,19人在第一个站下车,17人上车,现在火车上有63人。究竟火车上,开始时有几多人呢?不少人都认为答案是:63-17+19=65人。但上传这道数学题的网友却说:“要是你以为答案是65,那就错了!”她声称标准答案是46,令不少网民满头问号。她解释,“19人在第一个站下车”这一段,其实是用来混淆视听,计算时可以不去理会,故答案是:63-17=46,换言之,是要计算现在车上有多少乘客是从一开始坐到现在。不过,很多网民都难以接受,并坚称答案就是65,不少人都批评问题的措辞语意不清。
