   Monique Udell,a researcher with Oregon State University,got the help of ten domesticated(驯养的) dogs,ten dogs that live in shelters,and ten wolves raised by humans. Each of the animals was presented with a tasty sausage which they could smell,but not eat. The sausage was then placed inside a plastic container with a cover connected to a short length of rope. In order to open the container and eat the sausage,they had to pull on the rope while holding down the container,a task considered fairly simple for dogs and wolves. The experiment was conducted in two ways,one in which the animals were alone,and the other one in which they were with their owners.

   Surprisingly,none of the pet dogs was able to complete the task,and only one of the shelter dogs did so. However,eight out of ten wolves succeeded.

   The presence of a human made no difference. When the owner offered encouragements,four of the shelter dogs were able to access the sausage,but still only one pet managed to do it.

   Udell also made an interesting note: pet dogs have lived alongside humans for a long time,and therefore,when feeling confused about a new situation,they tend to look at their owners for help. The dogs were asking for help,while the wolves didn't give up and tried to solve the problem themselves.

   This experiment seems to show that something about being pets made dogs lose a big part of their motivation and this affects their problem-solving ability. Perhaps even more interesting is the fact that shelter dogs did somewhat better than house dogs — which indicates that being a pet makes dogs “softer” and less motivated to solve problems. However,things are not as simple as saying that wolves are “smarter” or “more creative” than dogs.

28. The sausages used in the experiment.

   A. had a disgusting smell

   B. came from some shelters

   C. were directly tied to a rope

   D. could be reached with very little effort

29. As for the pet dogs in the experiment,the presence of their owners .

   A. produced a negative result

   B. made them totally confused

   C. had little effect on their performance

   D. gave them the greatest encouragement

30. What does the underlined part “do it” in Paragraph 2 probably refer to?

   A. Pull on the rope. B. Smell the sausage.

   C. Open the container. D. Make a difference.

31. The experiment shows that .

   A. dogs hate being kept as pets

   B. pets have lost part of their wild nature

   C. shelter dogs seldom turn to others for help

   D. wolves are smarter and more creative than dogs

The United States of America is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a “traffic jam”.

While many cities in the United States have traffic problems,some of the worst are in Los Angeles,California,which is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around.

Experts say one possible solution to the traffic problems in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier,faster,less costly and more dependable than driving a car.

One suggestion is to reduce the cost of taking the bus. Also,Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car.

Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges,or tolls,would be for the most crowded roads. The tolls would be in effect during the times of a day when most people drive to work and home. These times in the morning and late afternoon are called “rush hour”. People would try to avoid driving on these roads,which would decrease the amount of traffic. Also,the money collected from these tolls could be used to improve the roads and public transportation system.

36. What does the passage mainly discuss?

   A. Money charged when driving cars.

   B. Causes of the heavy traffic jams.

   D. Solutions to solving traffic problems.

37. Why does Los Angeles have some of the worst traffic problems?

   A. Because it is a very big city with a large population.

   B. Because most people like to get around by car.

   C. Because public transportation is very popular there.

   D. Because there are not enough roads there.

38. From the passage we can infer that .

   A. driving their own cars cost less than taking buses

   B. taking buses is faster than driving cars in downtown area

   C. public buses usually come to the stop on time

   D. it is much easier to take buses than to drive cars

39. By marking out more special lanes on the freeways,they hope .

   A. buses can travel to more places in the city

   B. private cars can run much faster on them

   C. buses seldom get stuck in the traffic jams

   D. passengers can get on and off the buses easily

40. If people are charged on the most crowded roads during “rush hour”, .

   A. less air pollution would be produced

   B. there would be no traffic jam

   C. the freeways would be more crowded

   D. the number of cars on them would be smaller
