苏教小学数学一年级上册《分与合 3.练习三》教案_4

《练习三》教学设计教学内容：苏教版小学数学教科书第38页练习三1－5题。

本单元及本课时教材简析：本单元的教学内容是2－10各数的分与合，以及一些习题的编排。

在教学的过程中让学生初步感受到“分”与“合”的数学思想，了解10以内数的组成，增强学生的数感，为后续的学习20以内的数及加减法做好铺垫。

基于整个单元结构的安排框架中，练习三的内容是2－7分与合的综合练习。

通过形式丰富、多种层次的练习协助学生进一步体悟分与合的思想,熟练掌握2－7各数的分与合的内容，并逐步能强化有序思考，达到提升学生数学思维水平的目的。

学情现状分析：在幼儿园阶段绝大部分学生学习过10以内的加法，在生活中也有机会应用10以内数的分解组合，所以这方面的知识准备得比较好。

但需要看到的是，学生在数感方面的发展是不平衡的，少数学生对数的组成和意义理解有一定困难。

此外，学生的思维水平尚处于认知的初步阶段，绝大部分学生在数学学习过程中要借助实物来协助思维，且对数学思考的顺序性、严密性缺乏关照。

所以，对于练习三中“2－7分与合的综合练习”这部分知识教学，仍然要注意将意义理解与思维训练相结合，增强学生的生活经验的积累和对学习对象的直接感知。

设置大量有趣又有数学价值的数学活动，让学生充分感知、操作、理解、记忆2－7各数的分与合，体悟“分”与“合”的基本数学思想方法，为后续学习提供保障。

教学目标：1.通过练习,让学生进一步加深对2-7各数的分与合的理解与记忆。

2.在解决问题的过程中,进一步体会有条理思考问题的重要性,掌握有序分合的基本方法。

3.培养学生的语言表达水平和小组合作的意识，激发其发现规律、应用规律的积极主动性。

教学重难点及解决措施：1.教学重、难点：5－7各数分与合过程中有序思考的习惯培养2.解决措施：有序思考指按一定的逻辑思维顺序来思考并解决问题。

对于小学阶段的学生来说，这属于重要的数学思维水平，对于后续的学习有着重要的意义。

基于学生已经理解的10以内数，在教学本节课中，要特别注意引导学生分的时候，按分成的左边的数从小到大、右边的数从大到小的顺序来说一说，记一记。

For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark your answer on the Answer Sheet.Passage 1Have you ever noticed advertisements which say, “Learn a foreign language in 6 weeks, or your money back! From the firstday your pronunciation will be e xcellent. Just send …” and so on. Of course it never happens quite like that. The only language that is easy to learn is the mother tongue. And think how much practice that gets. Before the Second World War people usually learnt a foreign language in order to read the literature of the country. Now speaking the foreign language is what most people want. Every year many millions of people start learning one. How do they do it?Some people try at home with books and records or tapes; some use radio or television programs; others go to evening classes. If they use the language only 2 or 3 times a week, learning it will take a long time, like language learning at school.A few people try to learn a language fast by studying for 6 or more hours a day. It is clearly easier to learn the language in the country where it is spoken. However, most people cannot afford this, and for many it is not necessary. They need the language in order to do their work better. For example, scientists and doctors need to be able to read books and reports in the foreign language. Whether the language is learnt quickly or slowly, it is hard work. Machines and good books will help but they cannot do the student?s work for him.36.What do the advertisements mean?A. Y ou will learn a lot on the first day.B. Pronunciation is most important in language learning.C. Anyone can learn a foreign language without much money.D. It is possible to learn a language in less than 2 months.37.After the Second World War many people ______.A. found their mother tongue easy to learnB. learn to speak a foreign languageC. don?t learn to read in a foreign la nguageD. only learn to read in a foreign language38.Which, according to the writer, is the best place to learn a foreign language?A. Home.B. Evening classes.C. The country where the language is used.D. Places where people work.39.The writer of the passage thinks that ______.A. it?s difficult to learn a foreign languageB. it?s not necessary for many people to learn a foreign languageC. it?s not important whether a language is learned quickly or slowlyD. it?s much easier to learn a language toda y than in the past40.According to the passage, which statement is true?A. The mother tongue is easy to learn because it is an easy language.B. It is necessary for many of us to go abroad to learn a foreign language.C. Scientists and doctors want to speak an excellent foreign language, so they learn it.D. Though you have good machines and good books to help you learn a foreign language,you must work hard at it.Passage 2During the summer holiday there will be a different schedule for services for the university community. Specific changes for intercampus bus services, cafeteria (自助餐厅) summer hours for the school, hospital and recreational (娱乐的) and athletic (运动的) facilities (设施) will be posted on the bulletin board outside of thecafeteria. Weekly movie and concert schedules which are in the process of being arranged will be posted each Wednesday outside of the cafeteria.Intercampus buses will leave the main hall every hour on the half hour and make all of the regular stops on their route around the campus. The cafeteria will serve breakfast, lunch, and early dinner from 7 a.m. to 7 p.m. during the week and from noon to 7 p.m. on weekends. The library will maintain regular hours during the week, but shorter hours on Saturdays and Sundays. The weekend hours are from noon to 7 p.m..All students who want to use the library borrowing services and the recreational, athletic, and entertainment facilities must have a valid (有效的)summer identification card. This announcement will also appear in the next issue of the student newspaper.41.Specific schedule changes for which of the following facilities are listed in thisannouncement?A.

This information is not available.44.According to the announcement, a valid identification card is required to ______.A. ride on intercampus busesB. read announcements in cafeteriaC. make use of the school hospitalD. check books out of the library45.The main purpose of this announcement is to help members of the university to ______.A. make better use of intercampus busesB. secure faster service in the cafeteriaC. make more effective use of campus facilitiesD. obtain extensions on overdue library booksPassage 3Vitamins are chemicals that are necessary to keep us alive. Each type of food contains at least one useful vitamin. For example, fresh fruit contains a lot of vitamin C.Many years ago, people didn?t know about vitamins. When somebody was sick because of lack of vitamins, the doctors didn?t know what to do. For example, they didn?t know a child with rickets (软骨病) needed foods containing vitamin D, e.g. milk, eggs and oily fish.Doctors found out about vitamins by accident. One day a girl aged 4 was ill. The doctors tried to cure her by taking blood from her body but this didn?t succeed. Other doctors put hot c oals on her forehead and used other harmful methods. All these …cures?failed. The girl became worse and worse.One day the girl?s mother was peeling (削皮) apples in the kitchen. The girl came in and ate some of the peel. The next day, her condition was better. The mother thought about the peel and gave her some more. After some days, the girl was much better. The girl?s mother told doctors what had happened. They investigated the chemicals in apple-peel. The results were very interesting, so the doctors started to investigate other food. They discovered the girl had been ill with scurry (坏血病), caused by a lack of vitamin C. In previous centuries, this disease had killed thousands of sailors. When the doctors found out about vitamins, they advised people to eat a variety of different kinds of food.Now, we know this advice is good. Each person needs to eat such things as rice, meat, fish, vegetables and fruit. Milk and butter are good, too.46.which of the following statements is right?A. None of food contains one useful vitamin.B. All of food doesn?t contain one useful vitamin.C. There is n o food which doesn?t contain any useful vitamin.D. All food contains many useful vitamins.47.Before the vitamins were discovered, if a child was sick with rickets, the doctors ______.A. let him/her eat milk, eggs and oily fishB. let him/her take some medicineC. let him/her drink much water and take a restD. didn?t know what to do48.The girl became worse and worse because ______.A. the doctor took blood from her bodyB. the doctor didn?t find a correct way to cure herC. the disease couldn?t be curedD. the doctor only used a common medicine49.According to the girl?s story, we can see ______.A. the peel of the apple can cure lots of diseasesB. as long as we often eat apples, we can?t suffer from diseasesC. vitamin C can cure scurryD. people can cure their own diseases without doctors50.Each person needs to eat a variety of different kinds of food ______.A. because they contain a lot of vitamins and can build up his healthB. in order to raise his living standardC. because of their different kinds of sweet smellD. though he is poor nowPassage 4Mr. Richards was quite good at shooting with a rifle, and he had taken part in several competitions in his small town. He had never actually won a prize, but each time he had done well, and once he had come fourth.Then he had to go to a big city on business for a month, and as he had nothing much to do in the evenings there, he joined the local rifle club, and spent several pleasant evenings shooting there.The rifle club had a very good team, which used to take part in a lot of important shooting competitions. One of these took place while Mr. Richards was with them, and of course he went to see it. But one of the members of the club?s team suddenly fell ill just before the match, and the captain had to choose somebody else to take his place in a hurry. He had heard that Mr. Richards had taken part in several competitions already, and hehad seen for himself at the club that, although he was not really up to the standard of the club?s first team, he was quite a good shot. He therefore invited him to take the sick?s place.Mr. Richards felt greatly honored to be asked to shoot for such a good team, but he also felt very nervous, because he was afraid of making a fool of himself and letting down his team.In fact, he was so nervous that he could not keep his hands from trembling while he was shooting, with the result that he did very badly in the competition. When he took his score card to his captain, he said, “After seeing my score, I feel like going outside and shooting myself.”The captain looked at the card for a few seconds and then said, “Well, you had better take two bullets with you if you do that.”51.Which of the following statements is true?A. Mr. Richards was not very skillful at shooting.B. Mr. Richards had won a prize once in a shooting competition.C. Mr. Richards had taken part in quite a few shooting competitions.D. Some of the team members in the club are not good at shooting, either.52.Why did Mr. Richards join the local rifle club when he went to a big city on business?A. Because he wanted to win a prize in shooting competitions.B. Because he didn?t have much to do in the evenings.C. Because he liked meeting people.D. Because he wanted to share his experiences with others.53.Why was Mr. Richards chosen to take the sick?s place?A. Because he had won shooting prizes.B. Because he had taken some competitions and was not a bad shot.C. Because he was as good a shot as any member of the club?s first team.D. Because the captain was sure that Mr. Richards would do well in the competition.54.Which of the following is true about Mr. Richards? shooting?A. He was nervous, but he managed to shoot well.B. He missed his target.C. He did badly because he was sick.D. His hands were trembling, so he couldn?t shoot w ell.55.What did the captain mean by saying “you had better take two bullets with you if you dothat??A. He was giving Mr. Richards suggestions.B. He was not that disappointed at Mr. Richards? score.C. He was very angry at seeing Mr. Richards? score.D. He was trying to make Mr. Richards less uneasy.Part III ClozeDirections: There are 20 blanks in each of the following passages. For each blank there are four choices marked A, B, C, and D.

《GPS定位原理与应用》练习3

第三章卫星运动基础及GPS 卫星星历 1、何为卫星的轨道参数？卫星在空间运行的轨迹称为卫星轨道。

描述卫星轨道状态和位置的参数称为轨道参数。

2、作用在卫星轨道上的力分为哪两类，相应的卫星运动轨道为何？第一类，地球质心引力（中心引力）——卫星的无摄运动——二体问题的运动轨道第二类，摄动力（非中心引力）——卫星的受摄运动——摄动轨道（或瞬时轨道）3、研究卫星运行轨道的基本方法分为哪两个步骤？第一，忽略所有的摄动力，仅考虑地球质心引力研究卫星相对于地球的运动，在天体力学中，称之为二体问题。

第二，二体问题下地卫星运动虽然是一种近似描述，但能得到卫星运动的严密分析解，从而可以在此基础上再加上摄动力来推求卫星受摄运动的轨道。

4、何为开普勒三定律？其意义是什么？也叫“行星运动定律”，是指行星在宇宙空间绕太阳公转所遵循的定律。

开普勒第一定律（椭圆定律或轨道定律）：每个行星都沿各自的椭圆轨道环绕太阳运行，而太阳位于椭圆的一个焦点上。

开普勒第二定律（面积定律）：太阳和行星的连线（向量半径）在相等时间内所扫过的面积相等。

开普勒第三定律（调和定律或周期定律）：各个行星绕太阳运行的轨道长半轴的立方与公转周期的平方的比值为一常数，即K=T a 23=π24GM意义： ①开普勒定律在科学思想上表现出无比勇敢的创造精神； ②开普勒定律彻底摧毁了托勒密的本轮系，把哥白尼体系从本轮的桎梏下解放出来，为它带来充分的完整与严谨。

③开普勒定律使人们对行星运动的认识得到明晰概念。

它证明行星世界是一个均匀的（即开普勒所说的“和谐”）系统。

（这个系统的中心天体是太阳，太阳位于每个行星轨道的焦点之一。

行星公转周期决定于各个行星与太阳的距离，与质量无关）5、试绘图描述无摄卫星轨道，并阐明各参数的含义。

如图3-1，即为卫星无摄运动轨道。

a ——椭圆的长半径e ——椭圆的偏心率（对于GPS 卫星来说e ≈0.01）V ——真近点角（即在轨道平面上卫星与近地点之间的地心角距）Ω——升交点赤径（即在地球赤道平面上，升交点N 与春分点r之间的地心夹角）i ——轨道面倾角（即卫星轨道平面与地球赤道面之间的夹角）ω——近地点角距（即在轨道平面上近地点A 与升交点N 之间的地心角距）含义： a 、e 和V ，唯一确定了卫星轨道的形状、大小以及卫星在轨道上的瞬时位置；Ω、i ，唯一确定了卫星轨道平面与地球体之间的相对定向；ω，确定了开普勒椭圆在轨道平面上的定向。
