• The first one flew on April 12, 1981. A space shuttle has four main parts. They are the orbiter, the fuel tank, and two rocket boosters.
• In two minutes, the rockets run out of fuel and fall off. Parachutes slow their drop to the a. Then boats tow them to the shore. Rockets can be ud as many as 20 times. The big tank runs out of fuel in eight minutes.
• In 1999, a shuttle went up to fix the Hubble telescope. The Hubble is as big as a bus. The shuttle caught it. The telescope was held in the cargo bay. That’s an open place like the back of a pickup truck. The crew worked out in space to make repairs. They wore space suits.
太空梭是在地球与太空之间来回穿梭的机器。太空梭第一次试用是在1981年4月12日。太空梭由四部分组成：轨道飞行器，一个燃料箱和两个火箭助推器。
轨道飞行器看上去像一架飞机，它运载着工作人员。巨大的燃料箱携带着飞行器发动机所需的燃料，并与飞行器相连。火箭助推器的功用是促进起飞，它们连接在燃料箱的两侧。火箭在两分钟内用尽燃料，
就从高空掉下，降落装置让它缓慢坠入大海，然后由船只把它们拖回海岸。火箭能够这样重复使用二十次左右。巨大的燃料箱在八分钟后也会用尽燃料，它也会从高空坠落，支离破碎地坠入大海。而此时，飞行器则顺利进入了轨道。
飞行器最多能运载七名工作人员，他们的工作就是做测验，或许也会发射人造卫星。1999年，一架太空梭被派往太空去修复哈勃天文望远镜。哈勃望远镜大小如同一辆公交车。飞行梭首先扣住哈勃望远镜，随后把它固定在货物仓里。货物仓是一片空地，如同小型敞篷载货卡车的身体。工作人员在太空修理哈勃望远镜，他们身穿太空服，身后用一条长长的绳与梭体相连。修理完后，机械手把哈勃望远镜放回到轨道上。
当飞行器从太空返回时，要点燃飞行器的发动机，以此减慢梭体的速度，使其脱离轨道进入地球大气层。这时，梭体外部的特制陶片可以保护梭体免受梭体与地球大气层摩擦产生的高温。最后，梭体就像飞机一样，滑翔着降落在跑道。

导游词开场白
•What a job would you have had if you had lived in England in 1540? Chances are you would have been a farmer. Most people were. It took many people to rai enough food. Now just 2 out of 100 people in England farm. The rest work in towns and cities. This pattern is true in many parts of the w

orld.
•By rotating the crop grown in each field every year, the soil remained rich. Grasslands that could not be ud before could now be farmed. This rotation system allowed farmers to rai much more food, both for themlves and their animals.
•The invention of new farm tools also led to great change. Around 1700, the ed drill was invented. Before that time eds were scattered by hand. The ed drill dug trenches in the dirt and planted the eds. This tool was the first modern farm machine.
•如果生活在1540年的英国，你会从事什么工作呢？你很可能会成为大多数农民中的一员。当时种植日常所需的食物耗费很大的人力。而现在的英国100人当中只有2人留守农场，其他人则在城镇工作。现在世界各地都是这种模式。是什么原因促使人们离开农场呢？
•一些发现和发明让这一变化成为现实。轮耕制（或者叫变换农作物）就是其中之一。很
久以前，农民们已经认识到年复一年在同一块土地上种植同一种农作物，会让土壤变得贫瘠。因此，他们在耕种时总会空出一些田地来。
•18世纪早期，查理·汤孙德发现了这种在同一块土地上轮流耕种四种农作物的方法。有了这种方法，
田地就可以常年累月地持续使用。比如说，有四块地用来种小麦、苜蓿、大麦和芫青，通过每年种植不同的作物，土壤可以持续保持肥沃。以前闲置的草地现在也用来种植了。这种轮耕制让农民们为自己和他人的牲畜生产出更多的食物。
•罗伯特·贝克威尔是18世纪晚期的农场主，他想养殖优良的牲畜，于是就培养出优良的马匹、牛群和羊群。他培育出的一种绵羊不仅供应肉食还提供羊毛。
•农场新工具的发明引起了更大的变革。1700年前后，人们发明了条播机，它可以自行在土壤里挖坑播种。在此之前，播种都是人工进行的。条播机是第一台现代农机设备。作物轮耕、优良牲畜的养殖、新发明的农具使得用很少的人力生产出大量食物成为可能。
于是，成千上万的家庭就从农场迁往城市去了。

A. 夜晚眺望星空需要想象力。喜欢眺望星空的人们往往把星星看作是画图游戏中闪亮的圈圈点点。他们想象群星间有线条相连组成星座。星座就是看上去像人、动物或物体的一组星星。
D. 众所周知，猎户星座看上去像个猎人，他源于希腊神话中的一个英雄。要找到猎户星座，你首先得找到北斗七星。北斗七星看上去像一只有着长长把手的大杯子。当你找到北斗七星时，一转头，你就
看见了猎户星座！它由四颗亮星组成两个三角形。三角形的顶端看上去连接在一起，在它们相连接的地方，有三颗更亮的星星，它们组成猎户星的腰带。悬挂在腰带上的一些稍微暗淡的星星是猎户的宝剑。
E. 猎户星座由不同种类的星星组成。ß星组成猎户座明亮的肩膀。Betelgeu在阿拉伯语中的意思是“巨人的肩膀”。ß星本身巨大，它的直径是太阳直径的400倍，被称为超巨型星。然而ß星却是冷恒星，它的温度没有太阳的温度高。

C. 参宿七星组成猎户星的左脚，Rigel在阿拉伯语中是“脚”的意思。参宿七星看上去比ß星亮是因为它的温度很高，是太阳温度的三倍。然而就大小而言，参宿星和ß星相比则如同婴儿。
B. 在猎户座的宝剑旁边，有一个巨大的被雾笼罩的区域被称为星云，它是发光的气体和灰尘的混合物。这些气体飞快旋转着移动，可能还会形成新的星体。当新生成的星星闪烁的时候，猎户星会比现在更明更亮。

没有人知道风筝最初是什么时候制作的。
有关风筝的最早记载是在2000多年前的中国。当时有一个将军叫韩信，他是起义军的首领，他想推翻残暴的国王，但苦于手下兵力不足，于是决定挖隧道攻入王宫。他通过放风筝
来测量隧道长短。负责挖隧道的人随身携带着风筝线，当抵达线尽头时，他们就知道已经抵达王宫了。最后他们进入王宫庭院，击败了国王。
放风筝在日本已经有几百年的历史了。早在18世纪，人们在秋天放风筝，并在风筝上绑上大米杆，以示对大丰收的感谢。当一对夫妇生第一个儿子时，人们常常用放风筝的形式以示对婴儿的美好祝愿。
现如今日本在某些庆典活动上经常放风筝，比如新年伊始。风筝形式各异、大小不一，有的像动物，有的像英雄或神像。风筝节是日本很多地区每年一度的大型庆典活动。
bottle的音标
在西方国家，风筝用于科研领域。很多人都听说过本杰明·富兰克林和他的风筝。当时富兰克林研究电，他认为闪电也是电的一种形式，但却不明确。1752年，他试图查出真相，就在暴风雨天气放风筝，并在风筝上绑了一把钥匙。钥匙上闪现的火花，证明了他的想法是正确的。拜拜的英文>玄奥的意思
19世纪90年代，劳伦斯·哈格雷夫发明了箱形风筝。他用这种风筝去测试有关飞行的想法。1898年至1933年期间，美国气象局曾用箱形风筝来收集气象数据。怀特兄弟也曾用风筝做实验。正是从风筝上得到的启示帮助他们在1903年制造出了世界上第一架飞机。

Cell phone has altered human relations. There is usually a note on the door of a conference room, which reads “turn off your cell phone”. However, the rings are still resounding in the room. We are all common people with few urgencies to do. Still, we are reluctant to turn off the
phone. Turning on the cell phone symbolizes our connection with the world. Cell phone reflects our “thirst for socialization”. We are most familiar with the scene when a person suddenly stops his steps to edit short message, with his eyes glued to the phone screen, disregarding his location, be it in the middle of a road or beside a restroom.
