Although similar in appearance to hyenas(土狼), African wild dogs are nevertheless true wild canine(犬). They are a mixture of black, yellow, and white in such a wide variety of patterns that no two individuals look exactly alike. African wild dogs are widely distributed across the African plains but they do not live in jungle areas.
They are social animals, living in groups of usually from 2 to 45 individuals. A hierarchy（統(tǒng)團(tuán)） exists within the group,  but the animals are friendly to one another. The young and the infirm（體弱的） are given special privileges within the group.
African wild dogs use their sense of sight, not smell, to find their prey. They can run up to 55 km/h for several kilometers. In eastern Africa, they mostly hunt Thomson's gazelles, but they will also attack calves, warthogs, zebras, impalas, and the young of large antelopes such as the gnu.
Growing human populations have decreased or degraded the African wild dog's habitat and also diminished their available prey. Road kill and human persecution（迫害） have also had a negative impact on African wild dog populations. This species is also susceptible to a variety of diseases such as distemper, which is controlled in domestic .dogs. Conservation of the African wild dog's natural habitat must have the highest priority, as these dogs suffer in habitats modified by human intrusion（干擾）．

While small may be beautiful，tall is just plain uncomfortable it seems，particularly when it comes to staying in hotels and eating in restaurants.
The Tall Persons Club Great Britain (TPCGB)，which was formed six months ago to campaign for the needs of the tall，has turned its attention to hotels and restaurants.Beds that are too small，shower heads that are too low，and restaurant tables with hardly any leg­room all make life difficult for those of above average height，it says.
But it is not just the extra­tall whose needs are not being met.The average height of the population has been increasing yet the standard size of beds，doorways，and chairs has remained unchanged.
“The bedding industry says a bed should be six inches larger than the person using it，so even a king­size bed at 6′6″ (6 feet and 6 inches) is falling short for 25% of men，while the standard 6′3″ bed caters for less than half of the male population，” said TPCGB president Phil Heinricy，“Seven­foot beds would work fine.”
Similarly，restaurant tables can cause no end of problems.Small tables，which mean the long­legged have to sit a foot or so away from them，are enough to make tall customers go elsewhere.
Some have already taken note，however.At Queens Moat Houses’ Caledonian Hotel in Edinburgh，6′6″ beds are now put in as standard after requests for longer beds from taller visitors，particularly Americans.                                (2011·新課標(biāo)全國，B)
【小題1】What is the purpose of the TPCGB campaign?

A．To provide better services.
B．To rebuild hotels and restaurants.
C．To draw public attention to the needs of the tall.
D．To attract more people to become its members.
【小題2】Which of the following might be a bed of proper length according to Phil Heinricy?
A．7′2″. B．7′. C．6′6″. D．6′3″.
【小題3】What may happen to restaurants with small tables?
A．They may lose some customers.
B．They may start businesses elsewhere.
C．They have to find easy chairs to match the tables.
D．They have to provide enough space for the long­legged.
【小題4】What change has already been made in a hotel in Edinburgh?
A．Tall people pay more for larger beds.
B．6′6″ beds have taken the place of 6′3″ beds.
C．Special rooms are kept for Americans.
D．Guest rooms are standardized.

"If there is one thing I'm sure about, it is that m a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get  most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.
The nature of what is news may change .What basically makes news is what affects our lives - the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though .It's already happening in areas that may directly affect our lives, like genetic（基因的） engineering. In the future, I think  there will be more coverage of scientific explanations of why we feel as we do - as we develop a better understanding of how the brain operates  and what our feelings really are.
It's quite possible that in the next century newspapers will be transmitted（傳送）electronically from Fleet Street and printed out in our own home. In fact ,I'm pretty sure  how it will happen m the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read - sports and international news, etc.
I think people have got it wrong when they talk about competition between the different media（媒體）．They actually feed off each  other.  Some people once foresaw that television would kill off newspapers, but that hasn't happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet. it's never really pleasant to read something just on a screen.
【小題1】What is the best title for the passage?

A．The Best Way to Get NewsB．The Changes of Media
C．Make Your Own NewspaperD．The Future of Newspaper
【小題2】In the writer's opinion, in the future, _______.
A．more big political affairs, wars and disasters will make news
B．newspapers will not be printed in publishing houses any longer
C．newspapers will cover more scientific research
D．more and more people will watch TV
【小題3】What will probably be on in the newspaper made by yourself?
A．Sports and international news.B．A menu of important news.
C．The most Important news.D．what you are interested in.
【小題4】From the passage, we can infer ________.
A．newspapers will win the competition among the different meclia
B．newspapers will stay with us together with other media
C．television will take the place of newspaper
D．the writer believe some media will die out
【小題5】The phrase "feed off" in the last paragraph means ________ .

Today’s youth seem content to take the easy route and enjoy the ride of life. When tough situations arise, they often get annoyed and complain. How you live your teen years will have a profound influence on the rest of your life.
You must learn to use your time wisely. You may not see it now, but developing leadership characteristics at a young age is very important. As we get older, it becomes harder to overcome bad habits and replace them with good ones. Possessing leadership    qualities is essential, both in this life and in the world to come. There are certain qualities that one needs to develop in order to become a leader: justice, judgment, dependability, initiative, decisiveness, tact, integrity, enthusiasm, poise, unselfishness, courage, knowledge and loyalty. You may recognize these as good qualities to have, without realizing how they apply to leadership. The more these qualities are part of your nature, the more productive and enjoyable your life will be. All of these are qualities that one must possess to one degree or another.
Contrary to popular opinion, leadership is something   that is learned. No one is born a leader. We are all capable of exhibiting the   leadership qualities mentioned above — some just choose not to. Of course, not  veryone can be the “top dog”, let alone all the time. However, everyone does have the capacity to lead in some way — but action is required! Understand that learning is a fact of life—learning to ride a bike, learning to drive, learning to type, learning mathematics, etc. All of these activities require action. While we are born with many different abilities, if we do not use and develop them, those abilities will never come to fruition. Youth is an excellent time to start developing leadership characteristics. Take the time to study each one in detail. Put them into practice as you interact with other people. Determine which areas you are weak in, striving to always improve. Observe the leaders, and how     they handle situations and  carry themselves. Also, study the lives of great leaders. The results will serve you in this life — and beyond!
【小題1】The purpose of the second paragraph is to show that    .

A．one must overcome bad habits at first
B．a(chǎn)ll leaders have the mentioned leadership characteristics
C．the earlier and the more you develop leadership characteristics, the better it is
D．one must know how to apply the mentioned leadership characteristics first
【小題2】Not everyone can be a leader because______.
A．they are lazyB．they don’t learn
C．they don’t have the qualities mentionedD．they don’t develop their abilities
【小題3】What does the underlined sentence mean?
A．Everyone can be a leader all the time.
B．Everyone can not be a leader all the time.
C．Nobody can be a top leader all the time.
D．Nobody can not be a leader all the time.
【小題4】What is the best title for this passage?
A．Learn to be a leader.B．Everyone can be a leader.
C．Leadership characteristics.D．Leadership is something that is learned.

Is it necessary for a young man to have an apartment as a prerequisite（先決條件） for marriage? Housing has become a major obstacle（障礙） for Chinese young men hoping to start a family. China may breed a new group of bachelors, men caught in the trap of unaffordable houses.
Since early 2009, the housing market has once again become a hot pot at boiling point. Even with allowance（津貼） and special government policies, home prices in China's first-tier cities such as Beijing and Shanghai are riding the crest（波峰）of a rising wave. According to the "2010 China Marital Status Report" released on Dec 15, 2010, about 70 percent of women interviewed said that housing, a stable income and some savings were the main requirements for marriage.
From the report, we can see that housing is given top priority（優(yōu)先權(quán)） and that women see an apartment as essential(必不可少的) to show that the man is responsible and can provide for his family.
Personality and morals lay outside the top three matrimonial （婚姻的）requirements. Some women and their families hold the traditional position and take it for granted that the home issue should be the man's responsibility, which doesn’t agree with the contemporary independent spirit of women and gender equality. These marriage values reflect the fact that many women consider marriage another form of "social welfare".
Things may be different overseas. Social housing, provided by European authorities, offer the less wealthy people their own piece of real estate. Such housing is usually apartments in tall buildings with 10 or more floors on the outskirts of town, whose main advantage is the low rents.
For many Americans, houses don't pose an obstacle to getting married. They often buy a house after the wedding, because more and more people are reconsidering their real estate worship, and going back to a more rational(理性的) mode of consumption.
In Japan, renting is the custom for newly married young couples. Few young couples can afford to purchase property. Up to 67.1 percent of young couples choose to rent. Generally speaking, renters account for most people younger than 40 in Japan.
Young people should be free to enjoy being young, without the huge pressure of trying to buy property. Society should help create an environment for them to grow up. Don't let the poor bachelor group become a suffering layer（層） of our society.
【小題1】Which of the following is Not True according to the text?

A．Home prices have been extremely high since early 2009.
B．In the modern society, women don’t want to be independent.
C．Chinese government has already done something to control home prices.
D．Lots of Chinese young men couldn’t get married because of their economic capability.
【小題2】What does the underlined word “outskirts” probably mean?
A．urban areasB．rural areas（鄉(xiāng)下）
C．suburbsD．downtown areas
【小題3】Why do many women take housing as one of the main requirements for marriage?
A．Because they can’t afford a house.
B．Because they enjoy their social welfare.
C．Because their families want them to marry men with houses.
D．Because they think it’s a symbol of the men’s sense of responsibility.
【小題4】The author uses the examples of European countries, America and Japan to show that __________?
A．new couples in those countries like to rent houses
B．the situation is different in some foreign countries
C．it’s better to live in those countries than live in China
D．their governments have done more than Chinese government
【小題5】The last paragraph is mainly about the author’s hope that __________?
A．the society can develop rapidly
B．young people can lead a happy life
C．a(chǎn)ll the young people can afford houses
D．the poor bachelors can become rich and enjoy their life

Honesty comes in many forms. First there’s self-honesty. Is what people see the real article or do you appear through smoke and mirrors? I find that if I try to be something I’m not, I feel unsure of myself and take out a part from my PBA(personal bank account). I love how singer Judy Garland put it , “Always be a first-class version of yourself,instead of a second-class version of somebody else.”
Then there’s honesty in our actions. Are you honest at school, with your parents, and with your boss? If you’ve ever been dishonest, I think we all have, try being honest, and notice how whole it makes you feel. Remember, you can’t to wrong and feel right. This story by Jeff is a good example of that:
In my second year of study, there were three kids in my math class who didn’t do well.
I was really good at it. I would charge them three dollars for each test that I helped them pass. I’d write on a little piece of paper all the right answers, and hand them off.
At first I felt like I was making money, kind of a nice job. I wasn’t thinking about how it could hurt all of us. After a while I realized I shouldn’t do that anymore, because I wasn’t really helping them They weren’t learning anything, and it would only get harder down the road. Cheating certainly wasn’t helping me.
It takes courage to be honest when people all around you are getting away with cheating on tests, lying to their parents, and stealing at work. But, remember, every act of honesty is a deposit(儲(chǔ)蓄)into your PBA and will build strength.
【小題1】The underlined part “appear through smoke and mirrors” in the first paragraph means “     ”.

A．to be honest
B．to be unreal
C．to become clear
D．to come from an imagined world
【小題2】Which of the following can best explain Judy Garland’s words?
A．Be your true self rather than follow others.
B．Don’t copy others or you can’t be the first class.
C．Make efforts to be the first instead of the second.
D．Don’t learn from others unless they’re excellent.
【小題3】What does the author expect to show by Jeff’s story?
A．Honesty can be of great help.
B．A bad thing can be turned into a good one.
C．Helping others cheat can do good to nobody.
D．One should realize the wrong in his bad deeds.
【小題4】In the last paragraph the author mainly wants to express             .
A．one must be brave to be honest
B．it’s difficult to be honest when others are not
C．one should be honest when making a deposit
D．honestly in one’s actions can help him in the future

It is not unusual to see your desk-mate yawn (打呵欠) as he complains that he didn't have a good sleep the night before. Many teens don't get enough sleep because they have too much homework, which keeps them up at night. Some teens cannot sleep at night even when they want to.
Studies show that during your teenage years, the body's biological clock is reset, telling you to sleep later at night and wake up later in the morning.
But changes in the body clock aren't the only reason teens lose sleep. Lots of people have insomnia (失眠). The most common cause of insomnia is stress. But all sorts of things can lead to insomnia. These include physical discomfort, emotional troubles and even sleeping environment. It's common for everyone to have insomnia from time to time. But if it lasts for a month or more go and see a doctor.
Some people have a condition that causes stomach acid (酸) to move backward towards the chest. This produces the uncomfortable, burning feeling called heartburn. So even if the person doesn't notice the feelings of heartburn because he is sleeping, he may feel tired the next day.
Most teens have nightmares sometimes. But, if they are frequent, a person's sleep pattern can be seriously affected. The most common cause of nightmares is emotional problems, such as stress (壓力) or anxiety. If you have them a lot, it's a good idea to talk to a doctor.

They say that the real marathon begins at 35 kilometers — the rest is just a warm up. And sure enough, in 2009, at around the 36 kilometer point of the Beijing Marathon I experienced what runners call “hitting the wall”. I had been doing well until that point, but suddenly I felt a sharp pain in my leg. My pace slowed down dramatically and every brain cell in my head seemed to be screaming “stop!!!”
The last 5 kilometers were not fun; in fact, they were really hard work. Keeping motivated to run those last few kilometers was one of the hardest things I had ever done. But that is what makes running a marathon such a rewarding experience — if it were easy everyone would do it.
I have to admit it is sometimes not even easy to find the motivation to get out of bed, pull on your running shoes and head out into the morning to go for another run. These last two weeks of training for the Muztagata climb have been a little tough. I have been following my training plan for about three months but now I find that my original enthusiasm (熱情) has all been used up. Day after day of going to the gym is beginning to wear me down and there still seems so much longer to keep this up. I have begun to doubt that I am actually making any progress or getting any fitter and even thought that I might be going backwards!
These are all very common experiences for people who are working towards challenging, longer term goals and I have learned to recognize these “highs” and “l(fā)ows” in my energy and enthusiasm. Over the years I have learned a number of tricks that help me to deal with the days when my early motivation seems to have abandoned me for good.
【小題1】Many runners say that the real marathon begins at 35 kilometers because it is at this point that __________.

A．runners begin to enjoy running the marathon race
B．runners are worn out as if they are breaking down
C．the rest part is just the preparation for the race
D．the race is a rewarding experience for runners
【小題2】When people are working extremely hard towards challenging, _________.
A．they can keep themselves motivated all the time
B．they will never hesitate to continue carrying out their plan
C．they sometimes feel as if they stop making progress
D．they will fail to keep their spirits up
【小題3】What is the author going to talk about in the following passage?
A．How to get trained.
B．Tips for becoming a marathon runner.
C．How to meet challenges.
D．Tips for keeping motivation high.

Advertising gives useful information about which products to buy. But modern advertising does more than gives news about products and services. Today’s advertisements, or ads, try to get consumers to buy certain brands. Writers of advertising are so skillful that they can, sometimes persuade a consumer to wear a certain kind of clothing, eat a special kind of cereal, or see a movie. Consumers might never even want a product if they did not see or hear advertisements for it.
　　For example, you probab1y do not need the newest cereal in the supermarket. There are probably many cereal brands on your kitchen shelves. You may not have space on a shelf for another. But if you see ads about a new cereal that is your extra-tasty and has a free prize in the box, you may want it.
Advertising must get attention. To be effective, it must be exciting, entertaining, or provide some pleasure. The secret of writing good advertising copy is to offer a good idea as well as a product. The idea is what the ad is really selling. One example is an ad that says eating a certain cereal will make a person do well in sports. That cereal brand may sell better if consumers think it offers strength and energy.
【小題1】What is discussed in this passage?

A．The content of modern advertising.　　
B．The skills of modern advertising.
C．The results of modern advertising.　　
D．The writing of modern advertising.
【小題2】According to the passage, a good advertisement should     ____________.
A．be both persuasive and effective　
B．give people useful information
C．show people a product　　
D．show people a new idea of a product
【小題3】From the passage, we know that ___________________ .
A．modern advertising has less effect on customers 　　
B．once customers see ads about a new cerea1, they are sure to buy it
C．cereal can make people strong
D．cereal is a kind of food which is popular among people
【小題4】 What can we infer from the passage?
A．Customers can easily be persuaded by advertisements.
B．Customers should be persuaded by advertisements.
C．It’s impossible for customers to buy a product without advertisements.
