AIt is hard to say the first day of school in the United States because when the first day of school is and what happens on the first day of school are usually different by districts.The first day of school for many school districts in different states is on the day after the first Monday in September. In some other school districts, schools begin in mid- to- late August. For example, the Denver, Colorado schools go back in mid -August and schools in Cleveland, Ohio sometimes I like usually one week before the first Monday in September. The Boston, Chicago, New York city and San Diego schools start back on the Tuesday or Wednesday after the first Monday in September.Schools in Cleveland, Ohio used to start the school year on the day after the first Monday in September, but in the 1976 --- 1977 and 1977 --- 1978 academic years, the school year was affected by several bad snowstorms. In the 1978 --- 1979 school year, the Ohio Department of Education moved the start of the year to late August, one week before the first Monday in September. This went into effect in the 1980 --- 1981school year.In most school districts in Utah, the school year starts between August 25 and August 30, and goes until the last week of May or the first week in June next year.In American high schools, the freshmen class usually goes back one or two days before the rest of the school body for an orientation period. An orientation period helps the freshmen get familiar with the new school, its rules and surroundings.In some schools, freshmen classes have their photographs taken for identification purposes. Some high schools have tried to make the first week of school fun for incoming freshmen.1. According to the passage, which schools start their school year the earliest.A. Schools in Denver.B. Schools in Cleveland.C. Schools in New York City.D. Schools in Boston.2. Why did the Ohio Department of Education change the start of the school year?A. Because of some political events.B. Because of the entrance examinations.C. Because of the increasing number of students.D. Because of the extreme weather.3. How many months does the school year last in schools in Utah?A. About seven months.B. About eight months.C. About nine months.D. About ten months.BIf you want to become a fluent English speaker you should take some advice. There are four skills in learning English. They are reading, listening, speaking and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills you should first master the skills of reading and listening.Read as much as you can. But your reading must be active. It means that you must think about the meaning of sentences, the meaning of unfamiliar words etc. There is no need for you to pay much attention to grammar or try to understand all the unfamiliar words you come across, but the fact that you see them for the first time and recognize them whenever you see them, for example, in other passages or books, is enough. It would be better to prepare a notebook for yourself so you can write down the important words or sentences in it.As for listening, there are two choices: besides reading, you can listen every day for about 30 minutes. You can only pay attention to yourreading and become skilful at your reading, and then you can catch up on your listening. Since you have lots of inputs in your mind, you can easily guess what the speaker is going to say. This never means that you should not practice listening.For listening you can listen to cartoons or some movies that are specially made for children. Their languages are easy. Or, if you are good at listening you can listen to VOA or BBC programs every day. Again the thing to remember is being active in listening and preferably taking some notes.If you follow this pieces of advice you are speaking and writing will improve automatically, and you can be sure that with a little effort, they will become perfect.4. According to the author, which should you improve first amount the four skills.A. Reading and listening.B. Reading and writing.C. Writing and speaking.D. Speaking and listening.5. To improve your reading, when you read you should .A. look up all new words in the dictionary.B. spend more time studying grammar.C.think about what you are reading actively.D. copy as many words and sentences as possible.6. The author seems to agree with the view that .A. everyone should listen to VOA or BBC programs every day.B. you needn't practice listening if you keep on reading every day.C. being good at reading is helpful in improving your listening.D. you should take notes of whatever you are hearing.7. The passage is mainly about how toA. choose suitable listening materials.B. deal with new words in reading.C. improve your English as quickly as possible.D. become good at English reading and listening.C.When you study abroad in France, you can expect to be treated the same as your native classmates, whether in a lecture or a discussion class.Well, you can study abroad in France and focus on nearly any subject, it's the students with a passion for the arts, architecture and history that rush to the country in the largest numbers.

France is also a main destination for architecture students, as you will see architecture in nearly every style:The Gothic Chateau de Chambord, built in the 1500s;Place Dauphine built in 1607 in Baroque style;The post modern housing development, Marne-la-Vallee.History students will find that France has been where the action is for quite some time. Over the course of the centuries, it has been the stage for the most important developments in the history of mankind, including the French Revolution, the rise of Napoleon and the rise of the Fifth Republic under President Charles de Gaulle. It was also the sight of the D-Day invasion(诺曼底登陆) of World War two.As a possible study abroad location France has a lot to offer because the combination of educational institutions(教育机构), arts and culture, and national history is second to none.8. What can we learn about studying abroad in France from the text?A. Few students choose to study in France.B. There are many lectures and discussion classes.C. Students from foreign countries are usually treated badly.D. France is the best place for students who love the arts.9. What can art students do on weekends?A. Enjoy V oltaire's music.B.

The text is most likely taken fromA. a study abroad websiteB. an architecture advertisementC. a history bookD. a fashion magazine11. According to the text, you can see many kinds of architecture in France, such as① the post- modern housing development②Baroque style buildings③ The Big Ben④Gothic architectureA. ①②③B. ①③④C.①②④D.Most Chinese people these days know what it is like to have an "English" teacher, since almost all pupils study English from their third year. Usually that first English teacher will be a young and lovely lady in primary school. But my first English teacher is no other than my father. Looking back, I can see that, when I was only a little girl, he created an English environment by providing me with flash cards, fun English- language toys and even toys which could sing English songs! The interest in English had certainly been awakened (唤起)when I began to learn English at school. Just imagine, he went a step further and asked me to learn new concept English by myself! I was confused and had much anger.I could not understand why a father could be so strict with his little girl. All the same, he never gave up and had gently insisted that I follow through with his ideas.At first I read stories with tears in my eyes and I actually hated them because they were too difficult for me. In the end, I became to love the funny stories and, to be honest, my father was always there with a helping hand. I'm sure that my English would never have got so far without his support. And that's why my father is not only my first English teacher but also my lifelong teacher. He is the one who awoke my interest, who gave me confidence and who offered me much needed help.1. Which of the following wasn't used by the father to create an English environment?A. Flash cardsB. Fun English language toysC. Dolls singing English songsD. English books2.

空气污染物测量方法空气污染物又称大气污染物，通常指以气态形式进入近地面或低层大气环境的外来物质。

2012年2月，国家环境保护部发布了新标准——《环境空气质量标准》(GB3095—2012)其中大气中目标检测污染物为SO2、TSP、PM2.5、PM10、NO2、CO、铅(Pb)、苯并[a] 芘、氟化物(F)、03。

其中TSP，total suspended particulate的缩写，称总悬浮颗粒物，指用标准大容量颗粒采集器在滤膜上收集到的颗粒物的总质量。

粒径小于100μm的称为TSP，即总悬浮物颗粒；粒径小于10μm的称为PM10，即可吸入颗粒；粒径小于2.5μm的称为PM2.5[1]。

空气污染物对居民的健康影响日益突出，其主要污染成分已经发现了与居民的心血管类疾病、呼吸道疾病等息息相关。

2012年室外空气污染成为我国疾病负担的第四名[2]。

目前世界上的此类研究中对空气污染物的测量方法各类，大致可分为估计法和模型法和仪器监测法三大类。

1、估计法此类研究方法是研究中的最常用的也是最直接的方法，一般是依靠一定的客观检测数据如空气质量指数和如研究者所处的距离主干道路距离等作为人群的暴露水平的参数。

具体的可以分为固定站点检测法和距离接近法两种。

1.1 固定站点检测法固定站点是指国家对空气中的常规污染因子和气象参数进行24小时连续在线的监测，将分析出的数据提供给环保局作为空气质量好坏参考，并辅助环保决策的国家空气质量监测站。

空气监测站在城市区域中均匀分布，是进行空气质量检测和分析的基础平台。

截至2012年9月底，我国74个城市的496个国控监测站点中，已有138个站点开展监测并发布数据，195个站点完成仪器安装调试并试运行，70个站点完成仪器招投标。

并完善了空气质量监测网络和信息发布制度[3]。

主要城市的站点资料可以从中国空气质量在线监测分析平台获取。

目前有关空气污染物的研究中使用最多的便是此类方法[4]。

You can do it after school or lunchtime. There are also chances to teach in school. Many schools now need LCF teachers because they know LCF provides excellent training and supplies LCF teachers with the best resources (资源). Come on and try it yourself at our local club near your home!21. In LCF clubs, children can_________.A. join fun painting and gym clubsB. get education at school clubs onlyC. learn with songs, games and cookingD. learn with stories, games and movement22. If you want to join an LCF club, you’d better NOT_________.A. post a letterB. send an emailC. go to the local clubD. make a phone call23. From the passage above, we can know_________.A. LCF is a language and science school in CanadaB. LCF has language clubs and music & gym clubsC. LCF music & gym clubs can be found just onlineD. LCF provides excellent training, teachers and doctorsB Some parents said that they had difficulty in getting along with their children. I heard many parents complaining that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are holding firmly at one another’s hands for reassurance. They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up crowded round listening to the same record. Their reason for thinking or acting in thus-and-such a way is that the crowd is doing it. They have come out of their cocoon (蚕茧) into a larger cocoon. It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly carved out a teenage market.These days every teenager can learn from the advertisements what a teenager should have and be. And many of today’s parents have come to award high marks for the popularity of their children. All this adds up to a great barrier for the teenager who wants to find his or her own path. But the barrier is worth climbing over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don’t care to share at once with your classmates. Well, go to it. Find yourself. Be yourself. Popularity will come — with the people who respect you for who you are. That is the only kind of popularity that really counts.24. In this passage, the author wants to tell_________.A. teenagers how to learn to decide things for themselvesB. readers how to be popular with people aroundC. parents how to control and guide their childrenD. people how to understand and respect each other25. According to the author, many teenagers think they are brave enough to act on their own, but in fact, most of them_________.A. have much difficulty understanding each otherB. lack confidenceC. dare not cope with problems single-handedD. are much afraid of getting lost26. What does the author think of advertisements?A. Convincing.B. Influential.C. Instructive.D. Authoritative(权威的).27. During the teenage years, one should learn to_________.A. differ from others in as many ways as possibleB. get into the right reason and become popularC. find one’s real selfD. rebel against parents and the popularity waveCAs you grow rapidly through your teenage years, you willexperience a lot of changes. The changes may seem difficult and theymay seem to happen quickly. Don’t panic! You will deal successfullywith them! You are a young adult now! With more responsibility, you will find more freedom to make your own choices. This is a time to be well informed about your choices so that you can make healthy balanced decisions that will help shape your future. You may already know your career path or you may have no idea at all what you want to do. Both situations are fine! Work hard and the right opportunity will present itself to you. Young adulthood means greater freedom and more choices. You will probably want to be independent. But try not to shut your family out of your life. You should learn to think of others even though you are old enough to look after yourself. Your family have been with you since you came into this world. It is also perfectly natural in this time for you to spend more time with your friends than your family. Choose your friends wisely. A true friend will stand by you no matter what happens. This period is part of the life cycle. There are some people who will be with you throughout life’s journey and there will be some people with whom you part and go separate ways. Leaving school can be hard. The reality is that you may not ever see all of your classmates again. You are a young adult. It is your life. No one can live it for you. The choices that you make from now on will be your choices. So making the right choices will be important to you. Life is for living. Enjoy your life wisely!28.
