Too many people want others to be their friends, but they don’t give friendship back. That is why some friendships do not last very long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend treat you. Learning to be a good friend means learning three rules. Be honest; be generous; be understanding.
Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven’t been honest you may lose your friends’ trust. Good friends always count on one another to speak and act honestly.
Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money on your clothes of course. Instead you have to learn how to share things you enjoy, like your hobbies and your interest. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them you help your friend know you better.
Sooner or later every one needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so you can understand the problem better.
No two friendships are ever exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practise honesty, generosity, and understanding.

With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds, reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete.
“The nuclear transfer of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
小題1: The aim of “Noah’s Ark” project is to _______.
A．make efforts to clone the endangered pandasB．save endangered animals from dying out
C．collect DNA of endangered animals to studyD．transfer the nuclear of one animal to another
小題2: According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A．available panda eggsB．host animalsC．qualified researchersD．enough money
小題3:The best title for the passage may be _______.
A．China’s Success in Pandas CloningB．The First Cloned Panda in the World
C．Exploring the Possibility to Clone Pandas D．China —the Native Place of Pandas Forever
小題4:From the passage we know that _______.
A．Kraemer and his team have succeeded in cloning a dog
B．scientists try to implant a panda’s egg into a rabbit
C．Kraemer will work with Chinese scientists in clone researches
D．about two thousand of species will probably die out in a century

Copywriting is the art of sending a message in writing, especially in advertisements, for the purpose(目的) of persuading someone to do something. This is especially true when writing descriptive(描述性的) copy. Why? Because customers’（顧客） senses don’t work on paper. They only work in person. That’s why copywriters have to create a sensory experience for their customers through their words.
When copywriters create descriptions, they often leave a lot to be desired. There is no interaction(互動) or experience. Descriptions should be descriptive. Successful descriptions should fill the gap of what customers would see, hear, smell, taste or feel as if they were standing before the product. Successful descriptions should also draw customers’ attention and create an actual event as if they could be right there.
Do you make cinnamon rolls(肉桂卷)？You wouldn’t want to describe them simply as “delicious” or “smell great”. Instead, you’d want to bring your customers to the experience of enjoying them. Something like this will work better: Completely NOT your grandma’s cinnamon rolls! Freshly bake them right in your own oven. As the strong pleasant smell of these excellent rolls begins to float in the air, your nose will start to feel excited and you’ll immediately know they are worth the wait.
When writing descriptive copy, choose the senses that are most proper and focus on them. If describing food, certainly you’ll think about not only what you’re tasting, but also what you smell and see. If you’re writing travel copy, you’ll focus on sights, sounds as well as feelings. Your goal is to have your readers close their eyes and imagine they are in the same experience as you are.
小題1:The purpose of copywriting is to        .
A．create a pleasant experience
B．develop customers’ five senses
C．persuade people to do things
D．give people rich imagination
小題2:The writer develops the third paragraph mainly        .
A．by cause and effect(因果)B．by order in space
C．by order in timeD．by examples
小題3: Which of the following would be the best title for the passage?
A．People’s five senses
B．Copywriting and advertisements
C．Descriptive copywriting
D．Copywriting and the five senses

The website “FarmersOnly.com” calls itself an online dating and friendship finder. The idea started in the mind of a man, Jerry Miller in Ohio. He wondered how farmers could meet new people who understand the life of a farmer. Jerry Miller is not a farmer but he represents a lot of farmers.
As he tells it, the idea for the site was planted when a farmer told him one day that she was recently divorced and would like to date. But someone would invite her to meet for coffee at nine o’clock at night, when she had to start her day at five the next morning.
So, in 2005, Jerry Miller launched his website. “You don’t have to be a farmer to be on FarmersOnly.com, but you do have to have the good old-fashioned traditional values of America’s Heartland.” 
You also have to live in the United States or Canada to be a member of the site. Some services are free, but a full membership costs fifty dollars for a year. As of last week the site listed more than 58,000 members. Many of them are farmers in the United States. Others are students or workers involved in some way with agriculture. Jerry Miller tells us about thirty marriages in the last year have resulted from his website.
Some farmers have also found love through a group, Singles in Agriculture, which was formed as a nonprofit organization in 1986. It organizes gatherings that usually end with a dance, but is not a dating service. The purpose is to support educational and social activities that offer people a chance for friendship. Its website, singlesinag.org, says there are more than 1,000 members across the nation and as far away as France.

Howling is a behaviour commonly observed among a wolf pack. As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There are different explanations of a wolf’s howl and it appears that there may be more to discover.
One theory is that wolves howl to bond better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behaviour.
Indeed, there have been times when wolves have been seen one moment howling in a chorus, and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be “punished” for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status among its members? —Why do wolves howl for sure?
What is clear, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering.
Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of “roll call” where wolves all howl together to report their presence.
小題1:What is the possible similarity between wolves’ howling together and humans’ singing in chorus?
A．The act of calling each other.B．The sense of accomplishment.
C．The act of hunting for something.D．The sense of belonging to a group.
小題2:Why does Harrington think the “social bond” theory may be wrong?
A．Wolves separate from each other after howling.
B．Wolves tend to protect their hunting grounds.
C．Wolves sometimes have quarrels after howling together.
D．Wolves of low rank are encouraged to join in the chorus.
小題3:Researchers are sure that wolves often howl to ______.
A．show their ranks B．find their companions
C．report the missing onesD．express their loneliness
小題4:“Howling… is a contagious behaviour” (in the last paragraph) means _______.
A．howling is a signal for hunting
B．howling is a way of communication
C．howling often occurs in the morning
D．howling spreads from one to another

As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets sage. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.
Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attracted meteor shower(流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn’t be able to see the meteor shower as well, and I would surely be run over by a car.
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you’ve ever taken a flight at night, the view is beautiful, but you must remember that all the light you see is wasted electricity. The crew of the space shuttles see an even bigger picture of how extensive the wasted electricity is worldwide.
Additionally, electricity needs to be generated, and the generation of electricity creates pollution by giving off greenhouse gases. This affects the air we breathe and our quality of life.
Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny sea turtle hatchlings become lost and follow lights on the shore instead of heading towards the sea.
Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution. 
小題1:The author tells the story in the second paragraph mainly to _________.
A．remember the past beauty of the town.
B．stress the advantages of less pollution
C．show the great changes of the town
D．prove the bad effects of light pollution
小題2:In the passage the author advises people _________.
A．to try to reduce unnecessary light.
B．not to ignore the beauty around.
C．to set proper light for animals
D．not to destroy the animal’s living conditions.
小題3:What can be inferred from the passage?
A．Light pollution is difficult to deal with.
B．Light pollution is a threat to some animals.
C．Light pollution has nothing to do with global warming
D．Astronauts can’t see clearly in space due to light pollution.
小題4:What is most likely to be discussed in the paragraph which follows the last paragraph?
A．The author’s contribution to light pollution
B．Other sources of light pollution
C．Ways of reducing light pollution
D．More bad effects of light pollution

In the computer age, most of us take a broadband Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course. You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “l(fā)ast mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely(稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere. Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables(光纖電纜) promise to bring extremely fast Internet connections to more users.
Still, the “l(fā)ast mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication(跡象), it may not be too long before an Internet connection simply follows you wherever you go.
小題1:The underlined part “ a catch” (in Paragraph 2) probably means “________”.
A．a rare challengeB．a desirable plan
C．an efficient deviceD．a hidden problem
小題2:What can we know from the third paragraph?
A．Internet connection has not been popular in most cities.
B．Internet service providers care about rural customers.
C．Computer is popular in developing countries.
D．It is hard to bring Internet access to users in remote areas.
小題3: Paragraph 4 mainly tells us that technological advancements ________.
A．make TV and telephone available everywhere
B．bring great change to people’s everyday life
C．make it possible for more people to use the Internet
D．bring faster Internet connections to users
小題4:What may eventually settle the “l(fā)ast mile” problem?
A．The broadband connection’s getting faster.
B．More and more Internet users.
C．More and more Internet connections.
D．The rapid progress in cell phone technology.

There are hundreds of things that your parents controlled for you when you were a child．And it’s a good thing, too — kids need this kind of protection and assistance, because they aren’t mature enough to take care of themselves and make careful decisions on their own．
But eventually, kids grow up and become teens．It’s totally normal for teens to create their own opinions, thoughts, and values about life; it’s what prepares them for adulthood．But as you change and grow into this new person who makes his or her own decisions, your parents may have a difficult time adjusting themselves to it．
In most families, it’s this adjustment that can cause a lot of fighting between teens and parents．Teens get angry because they feel parents don’t respect them and aren’t giving them space to do what they like, and parents get angry because they aren’t used to not being in control or they disagree with the teens’ decisions．
It’s easy for feelings to get very hurt when there are conflicts like these．And more complicated issues can cause even bigger arguments, because your parents will always be intent on protecting you and keeping you safe, no matter how old you are．
The good news about fighting with your parents is that in many families the arguing will lessen as parents get more comfortable with the idea that their teens have a right to certain opinions．It can take several years for parents and teens to adjust to their new roles, though．In the meantime, concentrate on communicating with your parents as best you can．
Sometimes this can feel impossible — like they just don’t see your point of view and never will．But talking and expressing your opinions can help you gain more respect from your parents, and you may be able to reach a compromise that makes everyone happy．Keep in mind, too, that your parents were teens once and that in most cases, they can relate to what you’re going through．
小題1:Why do parents always want to control their children?
A．They are afraid to lose their children．
B．They want to protect their children．
C．They don’t believe the ability of their children．
D．They can’t accept their children are growing．
小題2:The author suggested that teenagers ________．
A．fight with their parents bravely for their rights
B．obey their parents without any doubt
C．communicate with their parents actively
D．persuade their parents in as many ways as possible
小題3:It can be inferred from the passage that ________．
A．most parents will give in while fighting with their children
B．the conflict between parents and teenagers can be solved
C．the only way for teens to get freedom is to leave home
D．only few parents do well in facing the growth of their children
