Research advances over the past decade have told us that, with a little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves!
So, we can clone things, but why would we want to?
Of all the reasons, cloning for medical purposes has the most potential to benefit large numbers of people. How might cloning be used in medicine?
1. Cloning animal models of disease
Much of what researchers learn about human disease comes from studying animal models such as mice. Often, animal models are genetically engineered to carry disease-causing mutations(變異) in their genes. Creating these transgenic(轉(zhuǎn)基因的) animals is a time-intensive process that requires trial-and-error and several generations of breeding(培育). Cloning technologies might reduce the time needed to make a transgenic animal model, and the result would be a population of genetically identical animals for study.
2.Cloning stem cells(干細(xì)胞) for the treatment of diseases
Stem cells are the body's building blocks, responsible for developing and repairing the body throughout life. As a result, they might be used to repair damaged or diseased organs and tissues. Researchers are currently looking up cloning as a way to create certain human stem cells for the research of diseases.
3. Cloning farm animals for drug production
Farm animals such as cows, sheep and goats are currently being genetically engineered to produce drugs or proteins that are useful in medicine. Just like creating animal models of disease, cloning might be a faster way to produce large herds of genetically engineered animals.
小題1:From Purpose One, we can infer that      .
A.most transgenic animals are clone
B.most animals carry engineered genes
C.most transgenic animal models are not cloned
D.most animals carry disease-causing mutations in their genes
小題2:It can be learned from Purpose Two that cloning technologies can be mainly use do    .
A.create damaged or diseased organs and tissues
B.clone genetically defined human stem cells
C.develop and maintain the body
D.repair the body throughout life
小題3:According to Purpose Three, cloning technologies can be mainly used to      .
A.speed up the producing of genetically engineered animals
B.produce drugs or proteins that are useful in medicine
C.raise genetically engineered cows, sheep and goats
D.produce large herds of animals for human beings

[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (認(rèn)知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.
  [2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生蟲引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (輸送) to the immune system to fight the infection.
  [3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.
  [4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

Science has told us too much about the moon that it is fairly easy to imagine what it would be like to get there. It is certainly not a friendly place. Since there is no air or water, there can be no life of any kind. There is not much variety of scenery either. For mile after mile there are only flat plains of dust with mountains around them. Above, the sun and stars shine in the black sky. If you step out of the mountain shadow, it means moving from the severe cold into intense (強烈的) heat. These extreme temperatures continually break rocks away from the surface of the mountains. The moon is also a very silent world, for sound waves can only travel through air. But beyond the broken horizon, you see a friendly sight. Our earth is shining more brightly than the stars. From this distance, it looks like an immense (巨大的) blue, green and brown ball.
小題1:The moon is an unfriendly place because                   .

Who’s in control of your life? Who’s pulling your strings? For the majority of us,it’s other people—society,colleagues,friends,family or our religious community.We learned this way of operating when we were very young,of course.We were brainwashed.We discovered that feeling important and feeling accepted was a nice experience and so we learned to do everything we could to make other people like us.As Oscar Wilde puts it,“Most people are other people.Their thoughts are someone else’s opinions,their lives a mimicry,their passions a quotation.”
So when people tell us how wonderful we are,it makes us feel good.We long for this good feeling like a drug—we are addicted to it and seek it out wherever we can.Therefore,we are so eager for the approval(贊同)of others that we live unhappy and limited lives,failing to do the things we really want to.Just as drug addicts and alcoholics live worsened lives to keep getting their fix(一劑毒品),we worsen our own existence to get our own constant fix of approval.
But,just as with any drug,there is a price to pay.The price of the approval drug is freedom—the freedom to be ourselves. The truth is that we cannot control what other people think.People have their own agenda,and they come with their own baggage and,in the end,they’re more
interested in themselves than in you.Furthermore,if we try to live by the opinions of others,we will build our life on sinking sand.Everyone has a different way of thinking,and people change
their opinions all the time.The person who tries to please everyone will only end up getting exhausted and probably pleasing no one in the process.
So how can we take back control? I think there’s only one way—make a conscious decision to stop caring what other people think.We should guide ourselves by means of a set of values—not values imposed from the outside by others,but innate values which come from within.If we are driven by these values and not by the changing opinions and value systems of others,we will live a more authentic,effective,purposeful and happy life.
小題1:.What Oscar Wilde says implies that        
A.we have thoughts similar to those of others
B.most people have a variety of thoughts
C.other people’s thoughts are more important
D.most people’s thoughts are controlled by others
小題2:.What does the author try to argue in the third paragraph?
A.Changing opinions may cost us our freedom.
B.We may lose ourselves to please others.
C.We need to pay for what we want to get.
D.The price of taking the drug is freedom.
小題3:.It can be concluded from the passage that         
A. it’s better to do what we like
B.we shouldn’t care what others think
C.we shouldn’t change our own opinions
D.it’s important to accept others’ opinions
小題4:.The author tries to persuade the readers to accept his arguments mainly by      
A.a(chǎn)nalyzing causes and effectsB.providing examples and facts
C.discussing questionsD.making suggestions

The Future of Education
David Kelly, founder of the Design School Stanford, said, “In the classroom of the future, education will be custom-made for each student. Every child will have a laptop programmed for his or her learning style and speed. At the same time, more students will go out into the community to learn from business owners. And you’ll see more retirees in the schools as teachers.”
A New Way to Pay
Turn your cell phone into a “mobile wallet” and speed through the checkout line. With a smart phone that uses the same technology as “tap and go” cards, you’ll be able to access your financial data fast. You can select a credit or debit card(借記卡)from the screen, and then tap the phone on the checkout console(操縱臺;控制臺).
High-Tech Guitar
A 26-year-old Australian designer has invented a brand-new way to be a rock star. The Misa Digital Guitar’s fret board looks like a traditional six-string’s but with no strings attached. There’s a touch pad (墊)where the sound hole normally is, and instead of plucking strings,(彈弦) you tap, drag, or brush the pad to “play” the instrument electronically.
The Future of Phones
Jason Chen, editor of the website gizmodo.com, makes his prediction. “Data connections will get even faster, and you’ll be linked to your environment by cell phone. Fcr example, when you go on vacation, you can point your phone at a monument(紀(jì)念碑) and it will give you information about what you’re looking at.’
Needle-Free Vaccines(無針接種)
Boston University researchers are working on a new method of inoculation(接種)—no injection necessary. A mild electrical charge from a small device, shaped like a gun, is used to drive the particles(粒子) into the body. The new idea beats the old needle method.
小題1:The passage mentions the following EXPECT        .
A.paymentB.medicineC.educationD.music instrument
小題2:What can we learn from the text?
A.Even a man with no music knowledge can be a rock star in the future.
B.Students should go out into the community to learn from business owners instead of staying at school to learn from books.
C.We can carry no cash while shopping in the future.
D.We can feel more pain with the method of inoculation.
小題3:In which column can we read the passage?

By 2050
Futurologists predict that life will probably be very different in 2050.
TV channels will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there is equipment that connects directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes(基因). Scientists have already produced clones(克隆) of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
小題1:
According to the passage, the following can be realized today EXCEPT __________.

Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.
The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(兩棲動物).
Who is to blame?
Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim(受害者)of habitat destruction.
Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”
In China the new reserve(保護(hù)區(qū))itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.
"The country's natural resources(資源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.
The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average(平均水平) of 11% and the rate in most developed countries.
Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment(投資) in such reserves at all levels.
小題1:What do we know about the IUCN?
A.A union for listing animals and plants on the earth
B.A group of volunteers who are interested in wildlife
C.An organization concerning the protection of rare species' survival
D.A government made up officials, scientists and experts
小題2: What can be concluded from the passage?  
A.All the protection methods can’t work.
B.The IUCN does most of the protection.
C.The efforts China makes has paid off.
D.Enough is done in wildlife protection.
小題3:Which of the following is not the cause of the disappearance of the animals?
A.Bad weatherB.Over-hunting C.Warmer oceansD.Habitat destruction
小題4:Which of the sentence is NOT true?
A.China has been paying great attention to protecting the natural resources.
B.China has set up a lot of natural reserves.
C.The natural reserves in China cover more than 15 percent of the nation's land area.
D.The rate of China's natural reserves is lower than the average of the world.

A person steps on what seems like solid ground but discovers with horror that the ground is giving way underfoot. The person struggles desperately but is trapped. There is no escape. Slowly the person sinks deeper and at last is gone. The solid ground was solid only in appearance. It was actually quicksand, which is a deep mass of fine sand mixed with water.
How is quicksand formed? Water pushes up from below the surface and is held by the sand. The grains of sand are forced apart by the water. They cannot hold any weight. The subsurface water may have come from a spring, a river, or a stream. Sometimes pools of water near beaches become filled with sand. When the soil under these pools does not allow for good drainage(排水), the sand can become stretches of quicksand.
Is it true that a person who steps into quicksand is doomed to die? No, for people have fought their way from quicksand to firm land again. It is panic(恐慌) that creates the condition that can result in death, for the more a person struggles, the worse matters become. Quick movements will make the sand yield for a time, but then it rushes back and settles solidly around the body.
People trapped in quicksand should either lie back with arms outstretched, or not move at all. When the weight of the sand around his body has displaced equals that person’s weight, the victim will stop sinking. With feet held still, and with slow movements of the arms, as in the backstroke(仰泳) in swimming, people have managed to roll to safety and reach firm ground.
小題1:Quick movements by a person trapped in quicksand will _______.
A.help the person reach firm ground
B.help prevent panic
C.make the same sand yield temporarily
D.make the sand hold the person’s weight
小題2:Quicksand is _______.
A.a(chǎn) mass of fine sand mixed with waterB.formed only along rivers
C.found below subsurface waterD.solid ground
小題3:Which statement does the article lead you to believe?
A.Stretches of quicksand are found only under the sea.
B.People should never try to escape from quicksand.
C.It is hard to keep calm if you fall into quicksand.
D.Only heavy people can be trapped in quicksand.
小題4:The passage mainly tells about _______.
A.what solid ground looks likeB.the nature of quicksand
C.stepping into quicksandD.escaping from quicksand

You know that pearls grow inside oysters(牡蠣), but would you ever think to look for diamonds inside an ostrich(鴕鳥)? Well, a hunter once shot an ostrich and discovered, to his great surprise, that the big bird had swallowed a bunch of diamonds. How could such a strange thing happen?
Like many other birds, the ostrich swallows small stones that stay inside its “gizzard”. The gizzard is a bird’s second stomach. It is where the food is ground up. The small stones help to grind up the food so it can be digested. The small stones do the chewing because birds don’t have teeth. In that case of the ostrich with the diamonds, the bird simply had expensive taste in rocks. It used the diamonds to digest its dinner.
Diamonds and stones aren’t all that an ostrich will swallow. If there are no stones around, it will eat just about anything. Sadly for ostriches in zoos, this can be a fatal habit. The tendency to swallow anything it sees has caused the death of many an ostrich. Cruel or careless people often throw things into the bird’s living space. They throw keys, coins, and even large objects such as horseshoes. The ostrich swallows them without hesitation. Coins can be the worst. Inside the ostrich they wear down to a razor-sharp edge. They will cut open the bird’s gizzard from the inside. When one young zoo ostrich died, 484 coins weighing more than eight pounds were found in its gizzard.
小題1:
Which of the following best expresses the main idea of the passage?
A.Birds often eat strange and funny things.
B.Ostriches will swallow anything to help them digest food.
C.One ostrich died with 484 coins in its gizzard.
D.Ostriches are often hurt by cruel or careless people.
小題2:
The ostrich is not smart enough to ______.
A.digest its own foodB.eat only diamonds
C.a(chǎn)void eating harmful objectsD.escape from the zoo
小題3:
The sentence “the small stones do the chewing” makes rocks seem as though they were ______.
A.importantB.a(chǎn)live
C.dangerousD.uncomfortable
小題4:
he word “fatal” in the third paragraph is another word for “______”.
A.foolishB.carelessC.deadlyD.cruel
