The doctors in Children's Hospital are asking for money for children's toys. Some children in the hospital must stay in bed for many weeks. Toys are needed to keep the sick children happy and quiet. Money for them can be sent to the hospital. After Mrs. Weeks read the story，she said，"This story gave me an idea." "You want us to bring some money for the toys." "We could bring some of our own toys for the children in the hospital, "said the boys and the girls one after another. "Well, your ideas would be nice, "Mrs. Weeks said，"but mine is different." "We could make some toys, "shouted one of them. Mrs. Weeks smiled. "Do you think you could make toys?" she asked. "Yes, yes, "the whole class answered. "Great! Let's begin to make toys tomorrow, "said Mrs. Weeks. On Saturday afternoon，Mrs. Weeks took the children to the hospital with the toys made by her students. The children in the hospital felt very happy to see the toys. So did the children in the class. A few days later，Mrs. Weeks read another newspaper story to the class: Some school pupils brought toys to Children's Hospital last week. The toys were made by the pupils of Grade Three in Green Street School. The doctors said，"We have never had so many wonderful toys. Our children are very happy with them. They say，'THANK YOU，GRADE THREE.'" (1)、The first newspaper story was mainly about sick children in children's Hospital. T A：T B：F (2)、Let the class make some toys and give them to the children in the hospital was in Mrs. Weeks' mind. T A：T B：F (3)、At first，the doctors in Children's Hospital wanted to get some money to buy toys for the sick children. T A：T B：F (4)、From the passage we can learn that what Mrs. Weeks really wanted to do is to ask her class to save money for toys. F A：T B：F (5)、The author's tone in this passage is enthusiastic. T A：T B：F 2、Places to stay in Britain are as varied as the places you visit. 在英国，住的地方随着你游览地点的不同而有所区别。Whatever your budget is the choice -from basic barn to small hotel, from tiny cottage to grand castle - is all part of fun. Hostels Cheap, good-value hostels are aimed at all types of like-minded travelers, who prefer value over luxury and you don't have to be young or single to use them. Britain's independent hostels and backpackers hostels also offer a great welcome. Facilities and prices vary, especially in rural areas, where some hostels are a little more than a bunkhouse (临时住房) while others are remarkably comfortable －almost like bargain hotels. Youth Hotels Founded many years ago to "help all, especially young people of limited means, to a greater knowledge, love and care of the countryside", the Youth Hotels Association is still going strong in the 21st century. The network of 230 hotels is a perfect gateway for exploring Britain's towns and countryside. B&Bs The B&B (bed and breakfast) is a Great British institution, In essence you get a room in somebody's house, and small B&Bs may only have one guest room, so you'll really feel like part of the family. Larger B&Bs may have four or five rooms and more facilities, but just as warm as a welcome. In country areas your B&B might be in a village or an isolated farm surrounded by fields. Prices reflect facilities: and usually run from around ￡12 to ￡20 per person. City B&Bs charge about ￡25 to ￡30 per person, although they're often cheaper as you go further out to the suburbs.

如何画根轨迹： In theory , the entire s-plane should be searched in order to find points satisfying the magnitude and angle condition . This however is unnecessary since the proper interpretation of the magnitude and angle condition yields several rules that facilitate the rapid construction of the root loci plot . Although this plot is approximate , it suffices for purpose of a preliminary study . The following rules are therefore to be considered as aids for an approximate root loci: 1.The root loci begin at the open loop poles. 2.The root loci end at the open loop zeros . 3.The number of separate loci is equal to the open loop poles. 4.The loci are symmetrical about the real axis. 5.Asymptotes of the root locus . 6.Root loci on the real axis. 7.The angle of arrival and departure . 8.Breakaway point on real axis. 9.Intersection of the root loci with the imaginary axis.
