Since the 1950s, most of the stars of pop music have come from Britain and America. Howver, in the last ten years, when many different kinds of music have established themselves on the pop scene, more and more stars have come from other countries.

Pop music changes all the time and new stars appear and become famous. For a musician to stay popular and still produced good, original music over a long period of time, is a sign of true star.

Most stars start their careers in a simple way---- playing in unknown night clubs or dance-hall where people want to dance to the music, not listen to it. They may have continued doing this for many years untill they get a “break”---- a chance to perform in a well –known place or get a recording contract. To become a star is the aim of every singer or musician and the dream of many a pop-crazy teenager.

However a group or star makes it to the top, they can be sure that their lives will change once they are successful. Ordinary teenagers living at home with their parents may suddenly find themselves rich enough to buy their own houses. An established superstar may be able to buy several.

Despite the large amount of money that are earned, life at the top is not easy for many stars.. The pop scene is hard work and many stars need to spend a lot of time away from home. For a lot of them, this means they have no home life and their personal relationships suffer. Despite great public success, life at the top can be very lonely.

A growing number of college students are applying to take entry tests for medical and dental （牙科的） schools among increasing graduate unemployment in Korea.

“I’ve decided to apply for the test to enter a medical college to become a doctor, changing from my original plan to prepare for a lawyer qualification exam in order to get a more stable job in the future,” said a 24-year-old college graduate, Lee, who majored in business administration during his undergraduate schooling.

The new medical and dental school system is getting popularity, attracting an increasing number of students every year since its appearance in 2004, as it is open to all college graduates regardless of their previous majors.

The Education Development introduced the new medical and dental education system, in which college students with bachelor’s degrees are allowed to study medicine or dentistry by taking the Medical Education Test (MET) and Dental Education Test (DET).

Ten medical schools and six dental colleges that have used the new system have received 4,377 applications (申请) for the entrance exams.

Applicants are getting younger compared with those in their 20s representing 76.9 percent of the total. The tests might be easier for students with biology and chemistry majors, but graduates from other majors are also applying for the tests.

Under the existing medical and dental education system, students should take a two-year premedical course followed by a four-year medical course.

Students graduating under the new medical or dental education system are given master’s degrees, while those graduates who studied under the previous system have bachelor’s degrees.

1.Why do more and more Korean students apply for medical schools?

A．Because doctors are highly respected in Korea.

B．Because they want to get a more stable job.

C．Because medicine is easier to learn than other subjects.

D．Because the medical education system is reasonable.

2. Students in the old system may spend _______ years at college to get bachelor’s degrees.

A．two B．four C．six D．seven

3. We can learn from the passage that _______.

A．it takes a longer time to get the master’s degree in the old system

B．students may find it a lot easier to get a bachelor’s degree in medicine

C．graduates from other majors like history are not allowed to apply for those schools

D．the new system are not so popular as expected because of its high unemployment

4. What would be the best title for the passage?

A．New Medical and Dental School System Is Carried Out in Korea

B．Korean College Students Have a New Job Choice

C．Korean College Students Rush to Medical and Dental Schools

D．Doctors Are Becoming Popular in Korea

It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”

You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不见的) blanket.

Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.

Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

1.In most scientists’ opinion, the global warming is mainly caused by ________.

A．solar activity B．volcanic activity

C．natural factors D．human factors

2.The text is developed by ________.

A．giving typical examples

B．following the order of space

C．analyzing a theory and arguing it

D．comparing and finding differences

3.The underline word “identical” in the last paragraph probably means ________.

A．totally different B．exactly the same

C．extremely important D．partly independent

4.Which of the following is not the cause of climate change?

A．volcanic eruption

B．cycles concerning the Earth’s going around the sun

C．changes in solar

D．floods and droughts

5.Which of the following can be the best title?

A．Are All the Scientists Really Scientific?

B．Where Is Global Warming Leading Us to?

C．Are Humans Definitely Causing Global Warming?

D．What’s the Relation of Global Warming and Greenhouse Gases?

The price of milk may be going up. There was not enough rain in some parts of the country last year and the bad weather may mean that a gallon (加仑) of milk will cost 41 cents more after October 1st.

California already has high milk prices and the California court does not want the price to go any higher. High milk prices will be very hard for some people. Families with many children will have to spend more money to buy milk. The poor and older people without much money will also be hurt by higher prices.

The court said that more milk from other states should be sold in California as the price of milk from other states is not as high. Some states got enough rain so their costs did not go up. People will then be able to buy the cheaper milk, meaning that unless milk producers bring their milk prices down, their milk will not sell.

The drought (干旱) around the country has meant market forces are likely to push milk prices up by as much as 41-cent a gallon by October 1st. Experts said this decision by the Californian court could reduce (减少) the effect of the price rise here.

The 41-cent increase would add to California’s already high milk prices so California must allow more milk producers from outside the state to sell their products there. This would then lead to increased supplies (供应), which would, as a result, stop milk prices from increasing.

1.Who will be hurt by high milk prices?

A．Young people.	B．Milk producers from outside California.
C．Rich people.	D．Families with lots of children.

2.What caused milk prices in California to increase?

A．Short supplies from other states.	B．Being short of rain.
C．The California court.	D．Children’s need for milk.

3.What will California do to keep milk prices down?

A．Force milk producers to lower their price.

B．Encourage people to drink less milk.

C．Get men to produce more rain.

D．Increase the supply of milk in the state.

It takes years of school to develop math skills, but learning about numbers starts earlier than you might think. Now according to a new study, at three months, babies have already started acquiring a concept (概念) of “how much”.

Previous research had suggested that very young babies can tell when the number of objects (物体) in a group has changed. But the babies in these studies were simply reacting generally to the fact that something had changed, they suspected.

Researchers of Harvard University studied 36 babies, all three months old. During the tests, each baby wore a hat with sensors (传感器). The babies watched a series of images on a computer screen. They showed the same object, such as a cartoon character. For a while, the number of the objects in the pictures didn’t change. Then the images began to display a different object, or a different number of one of the objects the babies had previously looked at. As soon as something changed, the babies’ brains responded with a specific pattern of electrical signals, which would be recorded by sensors.

By analyzing these signals, the researchers discovered that one part of the brain (near the top on the left side) responded when the object in the image changed. A different part of the brain (lower and on the right side) responded when the number of objects in the image changed. This was not the area of the brain that is involved in attention. That suggests that the babies’ brains are doing more than just reacting to a change in what they’re seeing – they actually seem to be able to tell number changes from other types of changes.

Numbers and amounts are important concepts in our lives. Even though babies are years away from adding, subtracting (减), multiplying, and dividing, their brains seem to be preparing for a time when they finally will.

1.Why were hats with sensors used in the study?

A．To record the images on the computer screen.

B．To remind babies of the changes of numbers.

C．To record the electrical activity of each baby’s brain.

D．To help babies concentrate on the computer screen.

2.What does the underlined word “They” in the third paragraph refer to?

A．Babies involved in the study.

B．Sensors worn by the babies.

C．Numbers marked on the objects.

D．Images shown on the computer screen.

3.Which part of the brain is responsible for responding to the changes of numbers?

A．The top.

B．The left side.

C．The lower and the right side.

D．The upper and the left side.

4.The last paragraph mainly implies that .

A．babies are in fact cleverer than they are thought

B．it is impossible to understand human brain completely

C．numbers play the most important part in people’s lives

D．the ability of babies remain a mystery to scientists

5.The purpose of the study is to prove that .

A．math skills should be developed as early as possible

B．numbers are easier for babies to judge than images

C．babies really do have some sense of numbers

D．babies can react differently to what they see
