This could end the worries of many parents fearful for their children’s safety on the roads. Until now the local government have been prepared to provide bus services for children living more than three miles from their school, or sometimes less if special reasons existed. Now it has been decided that if a group of parents ask for help in organizing transport they will be prepared to go ahead, as long as the arrangement will not lose money and children taking part will be attending their nearest school. The new plan is to be fired out this term for children living at Milton who attend Impington School. The children live just within the three-mile limit and the local government said in the past that they would not undertake to provide free transport to the school. But now they have agreed to offer a sum of money for a bus service from Milton to Impington School and back, a plan which has the support of the school’s headmaster. Between 50 and 60 parents have said they would like their children to take part. Final calculations have still to be carried out, but a government official has said the cost to parents should be less than £20 a term. They have been able to arrange the service at a low cost because there is already an agreement with the bus company for a bus to take children who live further away to Impington. The same bus would now just make one more journey to pick up the Milton children. The official said they would get in touch with other groups of parents who in the past had asked if transport could be provided for their children, to see if they would like to take part in the new plan. 50. What is the aim of the plan? A. To prevent the students’ road accident. B. To relieve the traffic pressure. C. To save time for the parents and students. D. To help the parents save money 51. How can the local government arrange the new bus service at a low cost? A. By letting the bus run in the morning only. B. By limiting the number of the students. C. By getting the support from the headmaster. D. By linking(连接) the new bus service with the existing one. 52. Which of the following is possible if the plan is carried out? A. The bus company will make much more money. B. The children can choose whatever school they like. C. The parents can get rid of their worries. D. The students in Impington school can have free bus rides. 53. This passage is most probably ______. A. a personal letter B. an advertisement C. a headmaster’s report D. a newspaper article C Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding? To see whether babies know objects are solid, T.Bower designed a method for projecting an optical illusion(视觉影像)of a hanging ball. His plan was to first give babies a real ball, one they could reach out and touch, and then to show them the illusion. If they knew that objects are solid, and they show surprise in their faces and reach out for the illusion and found empty air, they could be expected movements. All the 16-to 24-week-old babies tested were surprised when they reached for the illusion and found that the ball was not there. Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear or go to never-never land? Experiments done by bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to reappear. If the experimenter took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted(替换) a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But 16-week-old babies did not seem to notice the switch(更换). Thus, the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object. 54. The passage is mainly about ______. A. babies’ sense of sight B. effects of experiments on babies C. babies’ understanding of objects D. different tests on babies’ feelings 55. In Paragraph 3, “object permanence” means that when out of sight, an object ______. A. still exists B. keeps its shape C. still stays solid D. is beyond reach 56. What did Bower use in his experiment? A. A chair B. A screen C. A film D. A box 57. Which of the following statements is true? A. The babies didn’t have a sense of direction. B. The older babies preferred toy trains to balls C. The younger babies liked looking for missing objects. D. The babies couldn’t tell a ball from its optical illusion.
