   Many people will remember the flight of the space shuttle (航天飛機(jī)) Challenger, in June, 1983.The achievement of Sally Ride, America’s first woman astronaut to fly into space, made this flight especially memorable. Students from two Camden, New Jersey, high schools, however, are probably to remember Norma rather than Sally whenever they think about the flight.

       Norma didn’t travel alone. She brought about 100 companions along with her. Norma was an ant, a queen ant who, with her subject, made up the first ant colony (群體) to travel into space. The ants were part of a science experiment designed by students to test the effects of weightlessness on insects.

       The equipment designed by the students for their colony functioned perfectly throughout the long space trip. The young scientists and their teachers were very sad to find that their insect astronauts had all died at some point before the container was returned to the school and opened. The problem didn’t occur in space, but on the ground after challenger had landed. The container remained in the desert for nearly a week before the ant colony was moved. The hot, dry desert air dried out the colony’s container and the ants died from lack of moisture (水分).

       The project was termed success because it did provide useful information. Students will continue their efforts to pinpoint (精確找到) what went wrong. They will try to prevent the same difficulties from reoccurring on future missions. They don’t want to be discouraged either by the demise of the ants or by the $10,000 shuttle fare they will have to pay to send the next colony of ants into space.

The idea of micropayments--- charging Web users tiny amounts of money for single pieces of online content--- was basically put to sleep toward the end of the dot-com boom. In December 2000, Clay Shirky, a professor in New York University’s interactive telecommunications program (電信交互程序), wrote a manifesto (宣言) that people still quote whenever someone suggests using the idea. “Micropayments will never work,” he wrote, mainly because “users hate them.”

   But wait. Without many people noticing, micropayments have arrived--- just not in the way they were originally imagined. The 99 cents you pay for a song on the Internet is a micropayment. So are the tiny amounts that some operators of small web sites can earn whenever someone clicks on the ads on their pages. Some stock-photography companies sell pictures for as little as $1 each.

   “Micropayments are here” said Benjamin M. Companie, a lecturer at Northeastern University, “they just have not developed in the way that everybody expected.”

    From the earliest days of the Web until around the time of Mr Shirky’s manifesto, the expectation was that a handful of companies would provide platforms---or perhaps a single platform--- that would enable Web users to pay a penny or a dollar for a bit of content such as a newspaper article, or a research report. Simply clicking a link would complete the transaction (轉(zhuǎn)換).

   Sellers of content--- at the time, newspaper companies---were among the most interested in the idea as they looked for tax income that didn’t depend on advertising.

69．According to the first paragraph, we can infer that ________.

       A．people once failed to charge Web users

       B．a(chǎn)ll the Internet companies can’t earn profit

       C．it’s difficult for Web users to pay online

       D．micropayment costs people too much

70．Mr. Shirky predicted that ________.

       A．companies on the Internet would earn a lot of money

       B．Web users would never pay for the websites

       C．it was impossible to visit websites for free

       D．a(chǎn)ll the companies on the Internet would go bankrupt (破產(chǎn)).

71．You will have to pay for it, if you ________.

       A．visit some famous websites                 

       B．read latest news on the internet

       C．a(chǎn)dvertise for your products on some websites

D．download your favorite songs

72．What is expected by the sellers of content on the Internet?

      A．Better attitude from Web users.

      B．Understanding from Web users.

   C．A platform to help them realize micropayment.

D．More and more Web users.

     What is in the drug that makes you sick or dead ? For example , cocaine is harmful ,but what makes it harmful?

     I can’t tell you all about drugs , but I can   41 you think about them in this   42   way. Your body is a very complicated（復(fù)雜的） machine,  43   a lot of chemical machinery, all of which is finally turned   44   it all works together . Special chemicals, which we call drugs ,can affect it in many different ways.

     Some drugs are   45   when your body has a problem, as with disease-causing bacteria. Then someone may give you aspirin to keep your temperature from going too  46    or some penicillin（青霉素）  47  it stops the growth of some kinds of bacteria.  48   , all drugs are really poison,  49  if you take too much ,so you must always use them   50  .

   Why do some people take drugs like cocaine ? For a little while they seem to make you feel better , or happier .But  51   their effects have   52  ,your body has to pay an extra  53   to get back to normal. That makes  you want to get   54   of the drug .

Drugs like cocaine have their special effects because they act as   55   for your nervous system. They cut off some of your nerve pathways and take away some of your senses and your   56  . They make you want always more . And just a little too much can even   57   nerves to your heart and stop its beating .

Many of us worry about the   58  around us and what pollution does to us .How about your internal（內(nèi)在的） environment, and what goes on   59   you ? You control that all by yourself in what you put into your   60 . Most drugs are pollutants. You would not want pollutants in the air and water around you. Why would you want pollutants in your body ?
