Goats have more uses than you could ever imagine. Goat’s meat can be eaten and goat’s milk is becoming popular as a healthy choice to drink milk. Goat’s milk is easier to take in than cow’s milk and it is called universal milk as it can be used to bottle-feed most animals. In nutrition, it is also good. Goat’s skins are still used today to make gloves and other items of clothing. The initial reasons for domesticating (驯化) goats were to get goat’s hair, meat and milk. Goat’s skins were used up until the Middle Ages for making bottles to hold water and wine for people who were traveling or camping.
Just like sheep, goats are considered to be the first domesticated animal. The domestication process began over 10,000 years ago in a North Iranian town. A lot of people keep goats as pets nowadays.
Goats are easily trained and you can teach them to pull carts and walk on ropes. Goats are also known for escaping their pens(圈). If you have unsecured fencing, your goats will be interested in it and test it out and soon you will know where the openings are. Goats are also widely known for their ability to climb trees, although the tree generally has to be at a slight angle(角度).
If goats are raised correctly and trained from an early age, they never develop any bad habits. Goats will attack each other. However, if they’re corrected from an early age they never attack humans or other animals.

DNA is a substance（物质） that makes up genes. Everything alive has genes. Plans have genes. Animals have genes. Yo
u have genes.Genes are the basic units of heredity（遗传）. Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father.
Genes are a kind of code. A tree’s genes tell w
hat shape its leaves will be. A cat’s genes tell what color its fur will be. Your genes tell what color your eyes will be. Your genes tell what color your hair will be. Everything about you co
mes from the code in your genes.Genes line up on strands（链） called chromosomes（染色体） in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells.
Different parts of you are made of different kinds of cells. Your muscles are made of muscle celIs. Your skin is made of skin cells. The code in your genes tells your body to make different kinds of cells. The genes in each cell tell the cell how to work. They tell the cell when to make new copies of itself.
An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits（特质）， Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were later called genes.
In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases-diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by changing genes through a process called gene therapy.

For the lucky carriers of “Methuselah” genes, worries over smoking, eating unhealthily and not getting enough exercise may not be as necessary as to those of us without the special gene pattern .
The “Methuselah” genes could give extra protection against the diseases of old age such as cancer and heart disease. They could also protect people against the effects of the unhealthy lifestyles that we believe will lead us to an early death, scientists say. However, the genes are very rare.
The genes include ADIPOQ, which is found in about 10 percent of young people but in nearly 30 percent of people living past 100. They also include the CETP and the ApoC3 genes, which are found in 10 percent of young people, but in about 20 percent of people over 100 years old.
Some of those genes were discovered by a research group at the Albert Einstein College of Medicine in New York, led by Professor Nir Barzilai. The team studied the genes of over 500 people over 100 years old, and their children.
The studies show that tiny mutations (变异) in the make-up of some genes can greatly increase a person’s lifespan. Barzilai told a Royal Society conference that the discovery of such genes gave scientists clear targets for developing drugs that could prevent age-related diseases, allow people to live longer and stay healthy.
David Gems, a researcher at University College London, believes that drugs to slow ageing will become widespread.
“If we know which genes control longevity (长寿) then we can … target them with drugs. That makes it p
ossible to slow down ageing,” he told The Times. “Much of the pain and suffering in the world are caused by ageing. If we can find a way to reduce that, then we are obliged to take it.”
小题1: According to the article, which of the following is the most important if a person is to live to the age of 100?
| A．Eating healthy food every day. |
| B．Having the right types of genes. |
| C．Having a healthy lifestyle. |
| D．Taking drugs that prevent ageing. |
| A．10% | B．20% | C．30% | D．50% |
| A．The team studied the genes of over 100 people over 100 years of age. |
| B．The researchers found that mutations in certain genes lead to longer life. |
| C．The researchers found ways to develop drugs that could cure age-related diseases. |
| D．The study suggested that most people have genes that could lengthen their lives. |
| A．drugs to slow ageing will be very expensive |
| B．modern science will be able to find more longevity genes |

The gallery, at Sunderland University, England, is holding a new exhibition “If There Ever Was”. It focuses on scent rather than sight.
The innovative(创新的) idea is the brainchild of curator(馆长) Robert Blackson. His inspiration came from reading the book Fast Food Nation. The book discussed the use of artificial chemicals to flavor things such as milkshakes, making them smell and taste like strawberries, when they’re not actually made from them.
A smell can often conjure up(召唤) memories such as school dinners or a childhood holiday by the sea, but the smells on display, will allow visitors to experience smells their noses won’t have been able to pick out before.
“There’s a whole variety of diffe
rent smells, including some extinct flowers,” explains Blackson. “Some have been gone for hundreds of years.”One extraordinary fragrance(香气) is the aftermath(灾难的后果) of the first atomic bomb, dropped on Japan on August 6,1945.
There is also the smell of Clepatra’s hair, based on incense(熏香) that was popular among ancient Egyptians.
The Soviet Mir space station, which burnt up in the atmosphere in 2001, smells of charred(烧焦的) material (the space station caught fire).
Among the stranger smells is the “surface of the sun”.
“It is hard to sum up. It is an atmospheric smell, like walking into a room when the sun has been pouring i
n” says Blackson. “It gives a freshness, a sun kissed feel with a bit of metal. If you can say something smells hot, this is it.”A team of 11, including perfume designers, have been working on recreating the smells for the exhibition. James Wong, a botanist（植物学家）at Botanic Gardens Conservation International, UK, helped in the recreation of the smells of four extinct flowering plants.
He did this by closely linking the extinct flowers with the smells of existing ones. With the help of historical reports of how the extinct flowers smelled, he was able to remix the aromas(芳香).
The exhibition runs until June 6.Fourteen extinct and impossible smells are on display.

An independent college claimed to have become the first school in England to make Chinese a compulsory (强制的) subject for its pupils.
Richard Cairns, the headmaster of Brighton College, said the move aims to recognize the importance of China as the world’s fastest growing economy.
Chinese will become one of the core subjects at the 1,200-pupil college from September. At present the school has only a “handful” of native Chinese students, but it hopes to attract more in the future.
Mr Cairns, who made the announcement in his first week as head of the high-achieving college, said, “One of my key tasks is to make sure that the pupils at Brighton College are equipped for the realities of the 21st century, and one of those realities is that China has the fastest growing economy in the world.
“China has replaced Britain as the world’s fourth-largest economy. We in Britain need to face up to this challenge, see it for the trading opportunity that it is, and ensure that our nation’s children are well-placed to thrive (茁壮成长) in this new global reality.
“A better understanding of the language and culture of China will be hugely important to the advantage of the children of Brighton College.”
Mr Cairns said he hoped the Chinese children already at the college would help and encourage their fellow pupils to learn their language.
In order to lead the way, Mr Cairns, a historian from Oxford, plans to take part in the first Chinese class as a pupil. “I have agreed to join the first Chinese class as a pupil. I think it is the best way for me to show the pupils here how important I regard this new addition to our core subjects.”

| A．Chinese is a language spoken by the largest population in the world |
| B．it realizes the importance of China as the world’s fastest growing economy |
| C．Chinese is the easiest language for the students |
| D．there are many native Chinese students at the college |
| A．He sees it to be a threat. | B．He thinks of it as a danger. |
| C．He considers it to be an opportunity. | D．He regards it as an encouragement. |
| A．The Chinese students at the college have already helped their fellow students to learn Chinese. |
| B．The school is the first in England to make Chinese a compulsory subject. |
| C．Mr Cairns has just been made head of this high-achieving college. |
| D．In Mr Cairns’ opinion, learning Chinese will be a great help to his students. |
Krak krak!( Watch out, a leopard (豹)！)
Hok hok hok!( Hey, crowned eagle!)
Very good — you’ve already mastered half the basic vocabulary of the Campbell’s monkey, which lives in the forests of the Tai National Park in Ivory Coast. The adult males have six types of call, each with a specific meaning, but they can mix two or more calls together into a message with a different meaning.
Having spent months recording the monkeys’ calls in response to both natural and artificial stimuli (刺激物), a group led by Klaus Zuberbuhler of the University of St. Andrews in Scotland argues that the Campbell’s monkeys have a certain form of syntax(句法).
This is likely to be controversial because despite great effort to teach chimpanzees(大猩猩) language, they showed little or no ability to combine the sounds they learned into a sentence with a larger meaning. Syntax, basic to the structure of language, uniquely belongs to humans.
“Krak” is a call that warns of leopards in the neighborhood. The monkeys give it in response to real leopards and to leopard shouting broadcast by the researchers. The monkeys can vary the call by adding “-oo”: “Krak-oo” seems to be a general word for hunter, but one given in a special context – when monkeys hear but don’t see a hunter, or when they hear the alarm calls of another species.
The “boom-boom” call invites other monkeys to come toward the male making the sound. Two booms can be combined with a series of “krak-oos”, with a meaning entirely different to that of either of its single parts. “Boom boom krak-oo krak-oo krak-oo” is the monkey’s version of “Timber!” – it warns of falling trees.
If Zuberbuhler is correct, the Campbell’s monkeys can both vary the meaning of specific calls by adding something and combine calls to make a different meaning.

| C．fail to learn language from humans |
| D．are not related to the Campbell’s monkeys |
| A．Krak | B．Boom | C．Boom boom krak-oo krak-oo krak-oo | D．Krak-oo |
| A．Zuberbuhler has spent years in the forests |
| B．the writer isn’t sure of Zuberbuhler’s opinions |
| C．the Campbell’s monkeys are cleverer than other animals |
| D．the Campbell’s monkeys can express six meanings by calls |
