     A sandstorm refers to a high amount of wind occurring in sandy areas,usually in deserts,where the wind speed is able to lift the top layer of sand from the ground,and push it in every direction. The sand involved in the sandstorm can reach heights of about 3. 05 m—15. 24 m.

It is very dangerous to experience sandstorm. Sand can get into the nose,eyes,mouth and lungs. If you happen to be caught in a sandstorm,you must protect yourself by wearing masks,scarves and so on.

If you’re driving when such a storm approaches,it ,s advised that you pull off the road,since it's difficult to continue driving. This is also important since vehicles can fail in during sandstorms and you could end up stuck on the road.

Most sandstorms occur in spring,and during the daytime. Many of the areas around the Persian Gulf and the Sahara Desert are associated with the most serious storms. Since it's a natural phenomenon,it can't be entirely controlled. In areas that are natural desert regions,you can't always prevent a sandstorm. There's much evidence that the planet Mars has dust storms,and clearly,no human intervention (介人) is responsible for such. Though it can move whole sand dunes and destroy crops,a sandstorm is not without benefit (益处) .

36. Which of the following is TRUE for a sandstorm?

   A. It occurs not only in deserts but also on the coast.

   A. In the Sahara Desert in autumn.

   B. In the Sahara Desert in spring.

   C. Around the Persian Gulf in winter.

   D. Around the Persian Gulf in summer.

39. According to the writer,a sandstorm .

    Scientists are trying to teach robots to read,so they can understand road signs and shop names to “live” for themselves. Experts believe developing literate artificial intelligence should be relatively simple because computers are already able to turn scanned books into text.

    A team of roboticists are working on a test robot— named Marge—which has been fitted with advanced Optical Character Recognition (OCR) reading software. It is hoped the fledgling technology can be used in rescue operations and work out where they are going inside buildings from signs. The early prototype version has been fitted with a dictionary and spellchecker so it can interpret text which is not clearly written.

     Doctor Ingmar Posner,a roboticist at the University of Oxford,says that a machine that can read will be a significant step forward. “By reading a label on a closed door you can sometimes get a good idea of what can be found behind it,he tells New Scientist. u Reading can help you detect things you cannot directly see. M However,the robot has had difficulties working out what is and is not writing—and still cannot read text on curved surfaces.

    Dr Posner adds, “The OCR software does not cater for the fact that it might not be seeing text. It tries its level best to force everything into text一brick walls,chimney stacks,everything. ”

    Once Marge has successfully read a word,it scans news websites like the MailOnline to look at its context and establish a meaning. It has already been able to work out that Barclays is a bank and Strada is a restaurant.

   Dr Posner is working on the scheme with Peter Corke at the Queensland University of Technology in Australia. Gregory Dudek,from McGill University in Montreal,Canada,describes teaching machines to read as ‘‘ refreshingly original I personally believe that exploiting OCR methods in a mobile robotics context makes a lot of sense, ” he says. “In fact,once you reflect on it,there is no doubt it will be highly useful. ”

46. According to the passage,robots are taught to read to

   A. let them guide the way for people

   B. help doctors to make operations

   C. develop their potential intelligence

   D. make them do things by themselves

47. According to Gregory Dudek,applying OCR to robots is.

   A. simple   B. useful

   C. creative   D. successful

48. The underlined word “detect” in Paragraph 3 can be replaced by

   A. remember   B. discover

   C. control   D. ensure

49. Which column of the newspaper is the passage probably taken from?

   A. Science. B. Education.

   C. Travel. D. Economy.
