5 在隧道工程以及矿山爆破作业中，部分未发火的炸药残留在爆破孔内，很容易发生人员伤亡事故。为此，科学家制造了一种专门的磁性炸药，在磁性炸药制造过程中掺入了10％的磁性材料——钡铁氧体，然后放入磁化机磁化。使用磁性炸药一旦爆炸，即可安全消磁，而遇到不发火的情况可用磁性探测器测出未发火的炸药。已知掺入的钡铁氧体的消磁温度约为400℃，炸药的爆炸温度约2240℃～3100℃，一般炸药引爆温度最高为140℃左右。以上材料表明 [ ] A．磁性材料在低温下容易被磁化 B．磁性材料在高温下容易被磁化 C．磁性材料在低温下容易被消磁 D．磁性材料在高温下容易被消磁
6 阅读理解。 SOUTHPORT, ENGLAND-A British teaching union famous for strange ideas has supported proposal to employ dogs as classroom assistants. At the annual conference of the Professional Association of teachers in Southport, northwest of England, one person suggested properly trained dogs be able to keep order in primary schools. They can round up lost children and protect those who experience unfortunate"accidents". Wendy Dyble, a Sheetland Islands woman who teaches children up to age seven, made it clear to her fellow friends that she was not "barking mad". They obviously believed her, supporting her idea by 16 votes to 13, with a total of 63 abstentions. He said big dogs could help round up children, keep them in line, lick up the milk they spill on the floor and provide the extra eyes that a teacher needs to keep order."A big dog would also be helpful for breaking up fights and look for lost property, like gym shoes or dolls," Dyble said at the conference."The dog will also be useful in sniffing out smells that children do not own up to," she added. "It would be nice for the teacher not to have to go round sniffing each child to find the culprit." The idea was greeted by the Dog Defense League but less so by bigger teaching unions. A spokesman for Education Secretary David Blunkett, who is blind, said his guide dog was always popular with pupils when he visited schools. The Professional Association of Teachers, with around 35,000 members, is the smallest teaching union in Britain. It has an honour for occasional strange ideas. Earlier this week, its annual conference here suggested stopping exams because they lead to stress and introducing selection at the age of 12 based on physical coordination and manual skill in the use of hand. 1. According to the writer"s opinion, to employ dogs as classroom assistants _____. A. is a wonderful idea B. can improve the relation between children and animals C. is beyond ordinary people"s minds D. can make some teachers lose jobs 2. What Dyble said at the conference _____. A. gained some support from the members B. frightened everyone at the conference C. interested everyone at the conference D. caused some trouble to trained dogs 3. A spokesman for Education Secretary _____. A. once used a dog as classroom assistant B. sang high praise for Dyble"s idea C. would employ dogs as teachers D. benefited from dogs more than others 4. The last paragraph of this passage _____. A. has nothing to do with the topic of this passage B. shows there are too many exams in British school C. provides further facts about the teaching union D. shows the writer"s anger to the union
