Questions 1 ~ 10 :
Hello, everyone. Today I will introduce you the learning chains in Britain. Here the chains refer to schools linked together as part of a group. They can offer students many practical advantages.
When people are asked to name a language school, more often than not, they think of one of the large international chains of schools. Some are vast language teaching organizations with schools in many different countries and may teach just one language.
One of the main strengths of these chains is the fact that their name is
familiar to people all over the world. This can be a big advantage in the con-fusing world of language learning. Most students are bewildered by the large choice of schools and courses on offer, both at home and abroad, and so many prefer to choose a school which has a familiar name and an established reputation. Chain schools know this, and part of their success is due to effective marketing and advertising, which helps to keep their name well-known.
But chain schools should not be dismissed by serious students just be-cause they use clever marketing techniques. They have other important strengthens which can provide advantages to students. A school is only as good as its teachers and facilities, and many chains offer very high standards in both. More chains require that their teachers have internationally recognized qualifications and a maximum amount of teaching experience. It is important for chains to maintain these standards at all schools, because the reputation of the whole chain can be affected if one school performs badly.
Students also benefit from the standardized structure of chains. Most chains use the same text books in all their schools, and often they produce their own coursework materials. They also organize their courses in the same way which means that starting dates and course lengths are usually the same at all schools.
For students, one of the main advantages of this standardized structure is simplicity. If you cannot decide whether to study in the U. S. or Britain, for example, most chains allow students to start their language course at one school and continue at another, so they can experience different regions or different countries, as part of the same study trip.
Chain schools tend to be larger than single center schools, which can al-so have advantages for students. With larger numbers of students, school administrators can achieve a better mixture of nationalities in classrooms. This means that students can avoid being with other students who speak their language. This gives them the chance to meet students from other countries, and to practice their English with them.
Some chains offer students a very simple booking and enrolment procedure which is also useful. Application forms and enrolment procedures are the same for all schools, so students need only supply their details once. Students may find that they can book their course abroad through a representative of a chain school in their own town or city. Other chains offer a centralized booking facility, so students only have to contact one center to make a booking anywhere in the world.
Chain schools often operate in different locations, whereas a single school is likely to be based permanently in one building. Many chain schools operate temporary schools, particularly during the summer holidays. In Britain, they often use secondary school premises which are empty during the school holidays.
Studying English in an English-speaking country is the most effective way to learn the
language, but for many students this is only one stage of their learning career. Most students start learning English in their own country and they will probably want to continue learning once they return from their study trip. An international chain can usually offer you a continuous learning program from one country to the next.
Language school chains can offer students high standards of teaching
based on widespread experience. For students it can be a useful way of making learning more flexible.
Questions 11 - 13 :
M: Now, I' d like to say that I think that this government proposing to build more nuclear power stations in this country is really being stupid. The point about nuclear power is that we haven' t learnt to do away with the waste. We haven' t learnt to cope with the waste from it yet.
W: Well, I sometimes think that, you know, they' ve got an impossible job. I mean all the impression I get is that there is no alternative.., well, that' s the impression I get.
M: No, no, no I... I don' t agree with that at all. There are plenty of alter-natives. There' s the sun.., solar power.., that is a source that is always there, we always have it.
W: I don' t... I don' t quite see what you' re getting at actually, solar power,
what' s that?
M: Well, the heat from the sun, it can be used in solar panels on the tops of houses for heating, storing up power to heat water and to heat the houses, you know, some solar panels are in operation already and they are saving money...
W: That' s a good point actually, but is it really viable, that, I mean because
I'd...
M:Sorry it must be! And the one great advantage is that I can see, if the government set up small units to build solar panels and to install them, it would be creating employment which would improve the unemployment situation and bring terrific advantages.
W: I have heard that in England, I mean, there' s not enough sun, is there?
For, I mean, solar panels here?
M:Yes, well, that' s not quite true. I... there is quite a bit of sun.., you
may not feel the actual heat of it on some occasions.
W: No, you are right there !
M:But the light power from the sun will...
Questions 14 ~ 16 :
M : Cigarette?
W :No, thank you. I' ve given up, you know.
M:Oh.
W : It' s ten days ago. Haven' t had one.
M : Well, you don' t mind if I had one.
W: Well, all right, then... Oh my goodness ! That' s a terrible cough.
M: No, no, it' s not. It' s only... I only get it first thing in the morning.
W: That' s going to make you very unfit, you know.
M : No, it' s all right. It goes in a minute.
W:Why don't you try and give up?
M : Oh, no. I ought to, but I can' t. It relaxes me, smoking.
W: Really?
M : It does.
W:Well, have you ever thought of just cutting down?
M : Oh, no, that' s all very well but... I wouldn' t enjoy it. I depend a bit
on my smoking. I must say.
W:You should do it gradually. I mean.., well, if you tried.., have you
thought of just giving up one day?
M:Yes, oh well, yes, that is quite a good idea.
W:It is.
M : But I think I' d lose count or something.
W: Oh dear ! Well, it might be an idea if you started eating sweets.
M : Oh no, I couldn' t do that. I couldn' t possibly...
W:Why?
M:Well, it makes you fat.
W:Well, do you think that matters? Don' t you think it is better to be fat
than to be unhealthy?
M : No, I don' t. I' d rather be fat... Well, I' d rather be thin than fat, certainly.
W : Oh dear. Well. Hey ! I' ve got a good idea !
M:What' s that?
W:Why don't you go to a hypnotist? My sister did!
M : Oh, look, you don' t seem to realize that I like smoking. If I gave it up,
if I didn' t smoke at all, I' d probably end up attacking people !
W : Oh, don' t be so silly ! Of course you wouldn' t !
Questions 17 ~ 20 :
Farmers usually use plows to prepare their fields for planting crops. Plows cut into the ground, and lift up weeds, and other unwanted plants. However, plowing is blamed for causing severe damage to top soil by removing the plants that protect soil from being blown or washed away. Many farmers in South Asia are now trying a process called Low Till Fanning. Low Till Farming limits the use of plows. In this method of farming, seeds and fertilizer are put into the soil through small cuts made in the surface of the ground. Low Till Agriculture leaves much or all the soil and remains of plants on the ground. They serve as a natural fertilizer and help support the roots of future crops. They take in rain and allow it to flow into the soil in-stead of running off. It has been proved that Low Till Fanning increases har-vests and reduces water use, and this method reduces the need for chemical products because there are fewer unwanted plants. Scientists say Low Till Farming is becoming popular in South Asia, which is facing a severe water shortage. They say the area will become dependent on imported food unless water is saved through methods like Low Till Farming. Currently, more than150 million people in South Asia depend on local rice and wheat crops. Farmers grow rice during wet weather. During the dry season they grow wheat in the same fields. Farmers are using the Low Till Farming method to plant wheat after harvesting rice. Scientists say Low Till Agriculture is one of the best examples in the w0fld of technologies working for both people and the environment.
Questions 21 ~ 30 :
Today we take it for granted that the mail will be delivered daily at our door. But many years ago it might have been placed in a tree trunk or underneath a rock. In the early days of the mail no one could be sure about where or when it would arrive.
At the southern tip of Africa there was once a post office under a rock. In the old days the route from England to India was around the Cape of Good Hope. The journey was stormy and dangerous. It took six long months. Sailors often wished to send mail home, but they seldom met ships bound back to England. So at the cape the sailors would go .ashore. They headed for a certain large stone. On the stone were scratched the words "Look here-under for letters. " They would leave their letters there, knowing that the
next homeward-bound ship would stop and pick them up.
There was another post office like this at the southern tip of South America. During the gold rush days, boats sailed around Cape Horn to California. At Cape Horn was a keg nailed to a post. Boats coming from the east coast would send a small boat ashore to this post office. They picked up any letters in the keg. At the same time they mailed letters home that boats sailing east could pick up.
In the state of Washington stands the stump of a huge cedar. It, too, was once a post office. Settlers needed a place for the mail carders to leave their letters. Their houses were so widely scattered that the mail carrier could not reach all of them, and the post office was far away over rough roads. So the settlers found a tree that stood where several trails crossed. They cut the tree down ten feet from the ground, hollowed it out, and covered it with a roof. Inside, they nailed a row of wooden boxes. Each box was marked with a family' s name. The mail carder could leave letters there for everyone for miles around.
For the first few years after the English colonists came to America, there was no regular postal service. People gave their letters to any traveler who happened to be going in the right direction. Often they gave them to a peddler or a traveling shoemaker. When the traveler reached the town where the letter was going, he might stop at an inn. He would leave the letters there. But there they stayed until the .person they were addressed to happened to come by and stopped at the inn.
What about places like Virginia where there were very few inns? People who wished to send letters would leave them at one of the large plantations. The owners of the plantation would then send the letters on to a neighbor. The neighbor would do the same. It was a slow mall system.
After many years, regular mail carriers on horseback were hired. They went from one big town to another. Between New York and Boston, for ex-ample, there was one "postrider" a month. He traveled only by day and took two weeks for the trip. often the postrider left all the mail for a whole town at a crossroads store. It still took many weeks for a letter to reach the person it was addressed to.
Finally, about two hundred years ago, Benjamin Franklin was made postmaster for all the colonies. His first act was to make a long journey to find out the best routes for carrying the mail. Then he set up a line of post station between the northern and southern colonies. He ordered his postriders to travel by night as well as by day.
Franklin' s postriders could carry more letters in a shorter time from one colony to another. The letter service helped the young American colonies learn more about each other. They learned that they were all interested in the same things. This gave them the feeling of unity that later helped them win their independence.
In time, the nation set up its own government. But there were still only seventy five post offices in the whole country. Between cities along the coast, mail was sent in sailing boats. But most letters were carried from one post office to another in stagecoaches. Trips were three times a
week in summer and twice a week in winter. The stage stopped in all towns. Large and small. It stopped fifteen minutes in a small town and two hours in a larger one. But still the people of the town might reach the post office too late tocatch the stagecoach. Sometimes, too, the drivers forgot the mall or even
lost it. It still took a week for news to go from Washington D. C. to New York.
Today an airmail letter can travel across the world in much less time than that, let alone the e-mail through computers. A modern post office handles more mall in a day than the colonial carders handled in a whole year. You know that the letter you send will go anywhere you want it to go, and whenever.

笔试模拟题（一） 听力原文 Listening Directions: In this section, you will hear five short sentences. Each sentence will be spoken twice. At the end of each sentence there will be a pause. During the pause, you are required to fill in the corresponding blank according to what you’ve heard. Then write your answer on the Answer Sheet. Example: You’ll hear: Mr. White is leaving at 1:30 and won’t be back until 5:00, so you can call him after that. You’ll read: Mr. White will not be back before _________. From the sentence we learn that Mr. White will not be back before 5:00. Therefore you should write 5:00 in the corresponding blank on your Answer Sheet. Now the test will begin. 1.They have ordered 8,000 dozen Pure Cotton Bed Sheet at US$220 per dozen, CIF New York. 2.If you increase your order to 1,000 sets, we’ll reduce our price by 3%. 3.Sode is a company with over 50 years of experience of multi-service in over 70 countries. 4.Bill Mason, M-a-s-o-n, applies for Operations Manager, and Tom Hans, H-a-n-s, applies for Sales Administrator. 5.The gross weight is 128,934 kilograms, while the net is 123,467 kilograms. Section B Directions: In this section, you will hear ten short conversations. At the end of each conversation, a question will be asked about what was said. Both the conversation and the question will be spoken only once. After each question, there will be a pause.

xx语文全真模拟试题3 (四)阅读散文，回答20～26题神奇的丝瓜作者：季羡林（1）今年春天，孩子们在房前空地上，斩草挖土，开辟出来了一个一丈见方的小花园。周围用竹竿扎了一个篱笆，移来了一棵玉兰花树，栽上了几株月季花，又在竹篱下面随意种上了几颗扁豆和两颗丝瓜。土壤并不肥沃，虽然也铺上了一层河泥，但估计不会起很大的作用，大家不过是玩玩而已。 （2）过了不久，丝瓜竟然长了出来，而且日益茁壮、长大。这当然增加了我们的兴趣。但是我们也并没有过高的期望。我自己每天早晨工作疲倦了，常到屋旁的小土山上走一走，站一站，看看墙外马路上的车水马龙和亚运会招展的彩旗，顾而乐之，只不过顺便看一看丝瓜罢了。 （3）丝瓜是普通的植物，我也并没想到会有什么神奇之处。可是忽然有一天，我发现丝瓜秧爬出了篱笆，爬上了楼墙。以后，每天看丝瓜，总比前一天向楼上爬了一大段；最后竟从一楼爬上了二楼，又从二楼爬上了三楼。说它每天长出半尺，决非夸大之词。丝瓜的秧不过像细绳一般粗，如不注意，连它的根在什么地方，都找不到。这样细的一根秧竟能在一夜之间输送这样多的水分和养料，供应前方，使得上面的叶子长得又肥又绿，爬在灰白的墙上，，一片浓绿，给土墙增添了无量活力与生机。 （4）这当然让我感到很惊奇，我的兴趣随之大大的提高。每天早晨看丝瓜成了我的主要任务，爬小山反而成为次要的了。 我往往注视着细细的瓜秧和浓绿的瓜叶，陷入沉思，想得很远、很远……（5）又过了几天，丝瓜开出了黄花。再过几天，有的黄花就变成了小小的绿色的瓜。瓜越长越长，越长越长，重量当然也越来越增加，最初长出的那一个小瓜竟把瓜秧坠下来了一点，直挺挺的悬垂在空中，随风摇摆。我真替它担心，生怕他经不住这一份重量，会整个地从楼上坠下来落到地上。 （6）然而不久就证明了，我这种担心是多余的。最初长出来的瓜不再长大，仿佛得到命令停止了生长。在上面，在三楼一位一百零二岁的老太太的窗外窗台上，却长出来两个瓜。这两个瓜后来居上，发疯似地猛长，不久就长成了小孩胳膊一般粗了。这两个瓜加起来恐怕有五六斤重，那一根细秧怎么能承
听力材料： Questions 1 ~ 10 : Hello, everyone. Today I will introduce you the learning chains in Britain. Here the chains refer to schools linked together as part of a group. They can offer students many practical advantages. When people are asked to name a language school, more often than not, they think of one of the large international chains of schools. Some are vast language teaching organizations with schools in many different countries and may teach just one language. One of the main strengths of these chains is the fact that their name is familiar to people all over the world. This can be a big advantage in the con-fusing world of language learning. Most students are bewildered by the large choice of schools and courses on offer, both at home and abroad, and so many prefer to choose a school which has a familiar name and an established reputation. Chain schools know this, and part of their success is due to effective marketing and advertising, which helps to keep their name well-known. But chain schools should not be dismissed by serious students just be-cause they use clever marketing techniques. They have other important strengthens which can provide advantages to students. A school is only as good as its teachers and facilities, and many chains offer very high standards in both. More chains require that their teachers have internationally recognized qualifications and a maximum amount of teaching experience. It is important for chains to maintain these standards at all schools, because the reputation of the whole chain can be affected if one school performs badly. Students also benefit from the standardized structure of chains. Most chains use the same text books in all their schools, and often they produce their own coursework materials. They also organize their courses in the same way which means that starting dates and course lengths are usually the same at all schools. For students, one of the main advantages of this standardized structure is simplicity. If you cannot decide whether to study in the U. S. or Britain, for example, most chains allow students to start their language course at one school and continue at another, so they can experience different regions or different countries, as part of the same study trip. Chain schools tend to be larger than single center schools, which can al-so have advantages for students. With larger numbers of students, school administrators can achieve a better mixture of nationalities in classrooms. This means that students can avoid being with other students who speak their language. This gives them the chance to meet students from other countries, and to practice their English with them. Some chains offer students a very simple booking and enrolment procedure which is also useful. Application forms and enrolment procedures are the same for all schools, so students need only supply their details once. Students may find that they can book their course abroad through a representative of a chain school in their own town or city. Other chains offer a centralized booking facility, so students only have to contact one center to make a booking anywhere in the world. Chain schools often operate in different locations, whereas a single school is likely to be based permanently in one building. Many chain schools operate temporary schools, particularly during the summer holidays. In Britain, they often use secondary school premises which are empty during the school holidays. Studying English in an English-speaking country is the most effective way to learn the
