苏教版四年级语文教案——练习三教学目标：认识并理解“双音节词”和“三音节词”的定义，能够准确分辨它们。
通过游戏的方式激发学生的学习兴趣，让学生轻松愉快地掌握知识。
引导学生主动思考问题，培养其自主学习的意识。
教学重难点：重点：让学生掌握“双音节词”和“三音节词”的特点和定义。
难点：让学生通过游戏的方式准确地分辨“双音节词”和“三音节词”。
教学过程：一、导入（5分钟）1、课堂前期教师可以播放一些包含双音节词和三音节词的短句，让学生试着分辨其中的差异。
2、教师可举例子让学生分辨何为双音节词和三音节词，如：小鸟、小草、书包等都是双音节词，而电视机、天空、四合院是三音节词。
二、探究（25分钟）组织学生分组进行游戏，游戏规则如下：1、把单词卡片打乱放在桌子上，让学生一个个拿起来读单词。
如果读出的单词是双音节词，就放在一边；读出的单词是三音节词，就放在另一边。
2、在规定时间内完成任务，选出最多的队伍为赢家。
3、同时给予获胜队伍小礼品激励。
三、巩固（10分钟）组织学生小组合作，通过问答的方式进行检查，以检测学生是否已经掌握了双音节词和三音节词的特点和定义。
四、拓展（10分钟）学生以自己感兴趣的事物为主题，尝试创作一篇有关双音节词或三音节词的文章或故事绘本。
五、总结（5分钟）教师进行总结，强调双音节词和三音节词的定义。
同时，鼓励学生积极思考及自主学习的意识。
教学反思：本节课教师通过游戏的方式，让学生轻松、愉快地学习了双音节词和三音节词的定义及特点，并通过问答和创作来加深学生对知识的理解和掌握。
同时，也激发学生的学习兴趣和自主学习的意识。
在教学过程中，教师应该注意控制时间，保证学生能够充分参与到游戏中，并尽可能贯彻“以学生为本”的教学理念，让学生处于教学中心，发掘他们的学习潜力，助力他们发展成为自律、有创造力的人才。

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. Athletic and recreational.B. Food and transportation.C. Bookstore and post office.D. Medical and audio-visual.42.Times for movies and concerts are not listed in this announcement because ______.A. a film or concert occurs every Wednesday at 7 p.m.B. the full list would be too longC. films and concerts cannot be announced publiclyD. the full list is not ready yet43.According to the announcement, which of the following is true of special hours for thelibrary?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.
