For centuries, magicians have used various ways to shock the audience. We all have seen how a   36  performer carefully steps   37  a bed of burning coals -- barefoot. Then he walks across   38  a single burn on his feet. Is it mind over matter, or is it just physics? As it turns   __39 , walking on burning coals isn’t that hot as   40 . “The coals are hot enough to   41__  you, but if you walk quickly across them you   42  being burned.” says Jonathan Hall, a physician at Penn State University in Eric Pennsylvania.
That’s because some coals are made   43   burning wood chips. Wood has two   44__   properties(特性)for fire-walking, explains Hall. First, wood is an insulator(绝缘体)--it doesn’t   __45  heat very well. “It   46 _ time for heat to travel   47  the wood to your feet.” Hall says. If the performer walked across red-hot metal   48 , that would truly be   49 , because metal conducts, or transmits, heat very well. The metal would   50  burn a performer’s feet.
Second, wood has a low specific heat-- it doesn’t take much heat to   51  its temperature. Heat is a form of   52 . Temperature is a   53  of heat, in units of degrees. So   54  the coals are hot, the value(数值)of heat energy they contain is low. Thus, a well-trained performer can   55  such an amazing result.
Still, you don’t want to walk on burning coals, do you?

试题分析:【文章大意】本文是一篇说明文。文章讲述了魔法师的表演者为什么能走过火红的煤炭。原因有两个:一、煤炭是由小木块构成的,木头是热的不良导体;二、煤炭的能量不足够高,所以温度不会太高。快速走过不受伤害是可能的。
小题1:A考查形容词词义辨析及语境理解。此处daring勇敢的; dare敢; rough粗糙的;fearful害怕的。我们都看见过一位勇敢的(daring)表演者小心地光着脚在燃烧的煤炭上走。
小题2:C考查介词的用法。此处at在……点上;over跨越……之上;on在……上面; above在……上方。我们都看见过一位勇敢的表演者小心地光着脚在燃烧的煤炭上(on)走。
小题3:C考查介词的用法。此处with拥有;within在……之内;without没有; over在……之上。他走过燃烧的煤炭但他的脚上没有(without)一点烫伤。
小题4:A考查副词的用法。此处turn out意为:结果……。结果是,在燃烧的煤炭上行走没有它被想象的那么热。
小题5:B考查非谓语动词的用法。此处相当于walking on burning coals isn’t that hot as it is imagined. 结果是,在燃烧的煤炭上行走没有它被想象的那么热。故选B。
小题6:B考查动词词义辨析及语境理解。此处fire点火;burn燃烧;light点燃;flame火焰。煤炭热的足以把你烧死(burn)。
小题7:D考查动词词义辨析。此处prevent阻止; keep保持;ignore忽视; avoid避免。如果你足够快地走过,你就会不被烧着。
小题8:B考查介词及短语的用法。 此处be made of意为:由……组成。那是因为煤炭是有燃烧的木块构成。木头有两个理想的特征能使人在上面走过。
小题9:A考查形容词词义辨析。此处ideal理想的;classic经典的; favorite  最喜欢的;standard标准的。那是因为煤炭是有燃烧的木块构成。木头有两个理想的(ideal)特征能使人在上面走过。
小题10:A考查动词词义辨析。此处transmit传导;communicate交流; bring   带来; send送递。木头是绝缘体,它不能很好地传递热量。
小题11:B考查动词词义辨析。此处gathers聚集; takes花费时间; gains获得;stands忍受。木头需要时间把热量从木头传到你的脚上。
小题12:A考查介词的用法。此处through穿过; into进入;over跨越;pass通过。木头需要时间把热量从木头传到你的脚上。
小题13:B考查形容词词义辨析。此处unhappy不高兴的;unharmed不受伤害的; unhealthy不健康的; unprepared无准备的。如果表演者走过红热的金属而不受伤害(unharmed),那是真正的魔力。因为金属导热快,金属会很快地灼伤表演者的脚。
小题14:B考查形容词词义辨析。此处charming迷人的; magical有魔力的; tricky耍把戏的; fashionable时尚的。如果表演者走过红热的金属而不受伤害,那是真正的魔力(magical)。因为金属导热快,金属会很快地灼伤表演者的脚。
小题15:A考查副词词义辨析。此处instantly迅速地; constantly不断地; frequently频繁地;lately最近。如果表演者走过红热的金属而不受伤害,那是真正的魔力。因为金属导热快,金属会很快地(instantly)灼伤表演者的脚。
小题16:B考查动词词义辨析。此处produce产生; raise提升;提高; construct建设;create创造。木头拥有特殊的热量,他不需要很多热量提高(raise)温度。
小题17:C考查名词词义辨析及常识。此处power权利,电力;source资源; energy能量; strength力量。热量是能量的一种形式。温度是热量的衡量标准以度来计量。
小题18:A考查名词词义辨析及常识。此处measure量度;rank等级;estimate估计; rate比率。热量是能量的一种形式。温度是热量的衡量标准以度来计量。
小题19:D考查状语从句的连接词。此处what if要是;however然而;as if 好像; even though即使。所以即使煤炭是热的,但它含有的热量也是低的。所以受过良好训练的表演者能实现令人惊讶的结果。
小题20:A考查动词词义辨析及语境理解。此处achieve实现;arrive到达;draw画;take拿,花费。所以即使煤炭是热的,但它含有的热量也是低的。所以受过良好训练的表演者能实现(achieve)令人惊讶的结果。

Summer school is something a kid will never forget. For some, it's a way to advance past their classmates. For most, summer school is a requirement in order to graduate with their classmates. I can remember being forced into taking a summer school course. It was not the school that forced me into this awkward situation, it was my mother.
I was a 16-year-old kid in a new school. My school did not offer summer courses so I had to take my course at an alternative school in the city. It was an experience I will never forget. I was not concerned with making friends. I was there to get credit(学分)for a course that I should have received for the previous semester. It was my doing that landed me in the situation and it was important that I understood this.
The fees were the lowest but the experience was amazing. I enjoyed I didn’t miss the day. The course was from Monday to Friday for an entire month. I passed the course with an A. I was thrown into an awkward situation but actually enjoyed it. My friends didn't even know I took the course. Most of them were still sleeping by the time my course ended each day.
Awkward situations are so important for personal growth. This situation made me feel more independent. I made friends. I finally understood what sacrifice and hard work were all about. While attending college, I remembered how much I enjoyed summer school and I chose to take summer school in my first three years of college. Some kids get pushed too much but some don't get pushed enough. I was never pushed enough.
Enable your children to struggle for success. If your child needs summer school you explain to them why it's important. Some parents are surprised by the situation and may want to be more involved in their children’s education. Follow through and follow up.
小题1:Most students go to the summer school in order to ____.

If you're networking (建立人际关系) and nothing is happening, you might need to evaluate how you're doing it. Maybe you show up at each event and still feel challenged by the process. You aggressively talk to people, give out your cards, call endlessly to schedule an appointment but have no real success from your efforts. To help you gain a different future, here are ten habits you should avoid.
Ineffective networkers:
1. Lack patience. They expect immediate results and want business now, not tomorrow.
2. Constantly “selling” something. They see dollar signs every time they shake hands with someone.
3. Too many choices. If they offer a variety of products, they might try too hard to tell about all of them. Offering too much information sends a confusing message making it difficult for people to send referral (指点). Opportunities are all around us but when you're networking, only focus on one.
4. Change positions too often. If they move from company to company or do something totally different, it might be difficult for people to keep up with them.
5. Lack manners and respect. They interrupt others, talk with food in their mouth, aren't very polite and appear unprofessional. They call people during dinner or on the weekends without thinking whether the occasion is suitable.
6. Distribute too many cards and sales literature. They come while loading with brochures, flyers (传单), catalogues and samples.
7. Focus on themselves. Too much self­ promotion can leave the other person to feel unappreciated. Every sentence begins with “I” and is all about their business.
8. “Talking” instead of “giving”. They don't realize what other people sense when they are being very selfish. Others may think that they are being taken advantage of.
9. Lack authenticity (可靠性) and personal values. They may create unrealistic expectations and not deliver on their promises. Sometimes doing things without integrity (诚实) possibly twists the truth.
10. Poor communication and interpersonal skills. They have trouble speaking effectively, building relationships and following up.
Networking is a process that is an investment of time and money. If you find you're doing any of these habits, consider learning how to improve on these and maximize your results while networking. You'll start to get better at connecting with people and obtain more referrals.
小题1:This passage is meant for people who ______.
A.want to do more businesses
B.often take instead of giving
C.have poor communication and interpersonal skills
D.want to improve their interpersonal relationship
小题2:According to the second habit, we shouldn't ______ when we are networking.
A.sell thingsB.talk about dollars
C.pay attention to money onlyD.shake hands with everyone
小题3:When talking with others, you should ______.
A.give out your cards and brochures every now and then
B.talk about the quality of your product as much as possible
C.interrupt others when they make a mistake
D.let other people express themselves completely
小题4:Which of the following is NOT correct about a salesman's behavior?
A.He offers too much self­promotion during the conversation.
B.He considers carefully when he can get what he expects.
C.He only focuses on one opportunity when networking.
D.He keeps his promises and doesn't expect too much from others.

There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
小题1:What problem should be settled now in London?
A.How to protect the city’s property
B.Where to build its flood defences
C.How to use the Thames Barrier to protect the city
D.How to improve the function of the old flood defences
小题2:Which of the following measures can’t solve the heat wave disaster in Paris?
A.Putting up new types of buildings with a covering of bamboo
B.Having air-conditioners installed in elderly care homes
C.Forbidding the city to build“Flower Tower”
D.Encouraging architects to design new types of buildings
小题3:The major threats to Shanghai are          
A.increasing population and coal-fired power stations
B.rising sea levels and typhoons
C.extremely high temperature and rising sea levels
D.extra demands on energy consumption and typhoons
小题4:The purpose of the passage is      
A.to tell us how to protect the big cities
B.to give advice on how to defend natural disasters
C.to explain what causes flood and heat waves
D.to warn us of the increasing natural disasters in big cities
小题5:Which of the following would be the best title for the passage?
A.Big Cities Facing Big Disasters
B.Big Disasters in the Future
C.The Increase of Natural Disasters
D.Solutions to Natural Disasters

Empathy(同情心) lets us feel another person’s pain and drives us to help. Do any other animals feel empathy? Scientists recently found that rats(老鼠) do, too.
Most people don’t like rats. In many people’s eyes, rats are only bad. But Jean Decety and his partners at the University of Chicago did an experiment. It showed that rats are kind, warm-hearted animals. They can feel each other’s pain.
Scientists placed pairs of rats in plastic cages(笼子) for two weeks. During this time they got to know each other. Then they put one of the rats from each pair into a small container(容器) in the cages. The small container had a door. It was so designed as to fall to the side when the free rat touched it. Many of the trapped(困住的) rats squeaked(吱吱叫) to show their discomfort. The other rats of the pairs could see their suffering(受苦的) friends clearly.
In most pairs, the free rats would become very worried about their friends. They kept trying to save their friends again and again throughout the month. Scientists put the rats’ favorite chocolate in the cages, but the rats didn’t eat it until they had saved their friends successfully. Scientists also found that female rats seemed to act more empathetic than male rats.
“The results are the first to show that rats take action in response to another’s trouble,” Decety said. “Monkeys and chimpanzees have similar behavior. But unlike those animals, rats can be ready used in laboratory studies. They will help us to learn which parts of the brain lead to empathy and helping behavior and whether empathy is natural.”
小题1:A person with empathy is often _____.
A.kind-heartedB.cleverC.activeD.strong
小题2:Why didn’t the free rats eat the chocolate at first?
A.Because they were not hungry at that time.
B.Because chocolate was not their favorite food.
C.Because they wanted to save the trapped rats first.
D.Because they were afraid that the chocolate was bad.
小题3:Which of the following animals were NOT mentioned in the passage?
A.Monkeys.B.Chimpanzees.C.Rats.D.Cats.
小题4:What does the passage mainly tell us?
A.Rats can feel other animals’ pain.
B.Chocolate is rats’ favorite food.
C.Rats are empathetic and can feel each other’s pain.
D.Female rats are more empathetic than male rats.

Children, especially at young ages, are very creative. And creativity can be a glorious(极好的) thing. Look at all the amazing artists and architects that have created glorious pieces of history. Look at all the authors with the award winning books. Now I am not saying everyone is going to end up this way but creativity is an important part of growing up and becoming who you are. This should be encouraged in young children as well as the older children.
Young children grow up playing with make-believe. And so many people try to make their young child see that their invisible friend isn’t real or that talking when someone is not in the room is weird. To adults it is, but for small children it is them being creative. May it be them playing house, or chef, or playing with stuffed animals, it is their creative part coming out. Some kids can have fun playing with rocks and sticks and it’s because of their creativeness that they can do this. The invisible friend part is another part of being imaginative, and is not a bad thing since they will grow out of that phase(阶段). So encourage this and play along with them, play house, or stuffed animals or whatever they want to play. Help keep their imagination running. You can even make up games, like treasure hunts, or dinosaurs, super heroes; there is just so much you can choose from.
All this can help your children’s minds stay creative. The arts and music, even thoughts are an important part of life and important in our society. If we didn’t have and encourage creative thinking, we wouldn’t have had inventors, or philosophers, or as I said before, artists.
小题1:The underlined word “weird” is close in meaning to            .
A.familiarB.strangeC.commonD.natural
小题2:According to the author, if a child talks alone in a room, we should          .
A.let him be
B.stop him from doing so
C.give him some advice
D.know that he is suffering from loneliness
小题3:What is mainly talked about in the passage?
A.How creative artists and architects are born.
B.How to help children grow up in a healthy way.
C.What kind of activities children like.
D.How to help children to be creative.
小题4:The author of the passage would agree that          .
A.every child can become creative artists or inventors

Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes  in permanent teeth are also known as caries.
"Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too."
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
"It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation."
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.
小题1:From the passage, we know that Wagner Marcenes ______.
A.works as the leader of the Institute of Dentistry at Queen Mary, University of London.
B.and his researchers accumulate some studies to find out some ways to cure all major disease.
C.is in charge of the activity to estimate the infection rate with the collected and examined studies about all major studies.
D.thinks that the most serious problem caused by tooth decay is cancer that will last for a long time.
小题2:Caries is a disease that ______.
A.is listed in the most common of all 291 major diseases and injuries which will last for a long time..
B.is closely related to industrialized diet which calls for people to eat slowly.
C.increases in Africa now because developing countries are becoming developed countries.
D.will cause phychological disorder which will affect people’s communication.
小题3:The writer wrote this passage in order to ______.
A.arouse people’s concern about caries and take measures to deal with it.
B.tell the result of the Global Burden of Disease 2010 study.
C.warn people in Africa to adjust their diet to prevent caries.
D.tell doctors that caries affects a person’s quality of life.
小题4:What is the writer’s attitude towards tooth decay?
A.indifferentB.concernedC.angryD.negative
