The Antarctic Icecap is the largest supply of fresh water,representing nearly 2%of the world’s total of fresh and salt water. As can be seen from the table below, the amount of water in our atmosphere is over 10 times as much as the water in all the rivers taken together. The fresh water actually available for human use in lakes and rivers and the accessible ground water amount to only about one-third of 1%of the world’s total water supply.

Since the 1990s, education has been required for all South Africans from age seven to fifteen. Last December, the government announced that 70% of students passed their final examination to finish high school. In 2008, the pass rate was about 63%. There have been increases each year since then.
Professor Shireen Motala says basic education is no longer a problem in South Africa. Most children stay in school until they are about sixteen. The problem is that large numbers of them leave without completing high school.
Students take an examination known as the “matric”(高考) in Grade Twelve. Professor Motala says, “Less than half of the children who started school in 2000 sat for the matric last year. Many dropped out of school, so only around 45% took the matric. And the worry is where those students actually go.” Those who drop out have to compete with better educated people for jobs.
Educational researchers also point to another problem. South African schools do not produce enough students with the skills for higher education in maths and science. Many schools are not well-equipped. Children do not see laboratories, and, as a result, their science marks are not very good. They do not have libraries at school. Also, many teachers do not have the skills or training to do their jobs.
In South Africa, a number of teachers were poorly trained before. Secondly, teachers have been confused by the many educational reform efforts in the last fifteen years. Finally, language differences in the classroom have not got as much attention as they should, which is a huge problem. Subjects such as maths and science are taught in English starting at about the age of ten. But South Africa has eleven official languages.
South Africa’s minister of basic education promises a number of improvements. Angie Motshega says teacher development efforts will focus on subject and content knowledge, making sure that the correct teachers are in the correct jobs.
小題1:From the first paragraph we can learn that ______.
A.South Africans are badly in need of education
B.South African teenagers do very well at school
C.the South African government takes education seriously
D.South African teenagers have become more clever
小題2:What is the real concern of Shireen Motala?
A.Something is wrong with the country’s basic education system.
B.Most children have to find a job at an early age.
C.The final exam is too difficult for most children.
D.Most children cannot complete high school until they are 16.
小題3:South African students perform poorly in science for all of the following reasons, EXCEPT ______.
A.they don’t work hard enough
B.their schools do not have laboratories
C.they cannot get help from libraries
D.there are not enough skilled teachers
小題4:With which of the following would Shireen Motala most probably agree?
A.Schools should focus more on maths and science than any other subject.
B.More educational reforms should be carried out in South African schools.
C.The more teachers teach maths and science, the better marks students may get.
D.More attention should be paid to language differences in maths and science classes.

In the computer age, most of us take a broadband(寬帶)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(chǎn) rare challengeB.a(chǎn) desirable planC.a(chǎn)n efficient deviceD.a(chǎn) 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(農(nóng)村的)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.

Throughout seafaring history, ships and sailors have been lost to storms, accidents and war. Until recently, most of these ships were weak wooden sailing vessel (船只), their skeletons(骨架) quickly eaten away by sea creatures. Now, large vessels made of steel float on the seas. Thousands of these huge ships have been lost in times of war and in times of peace.
The bones of great metal ships, unlike the wooden vessels of old, survive the destruction of the sea long enough to become home and harbor for underwater life of all kinds. Shipwrecks(殘骸) often provide the only hard surface and structure at the sandy bottom of the sea, something many sea creatures need.
The ship has been underwater for only five days. Its surface is still clean. Six weeks later, the wreck is covered with a slimy layer of algae(海藻), but it is still recognizable as a ship. Soon, animals that need to attach themselves to a hard surface, like the feather duster worms, make the wreck their home.
In warm waters, coral polyps(珊瑚蟲) settle on the wreck and begin the process of building a rock-like crust on the ship. Small fish are attracted on all of these creatures. Larger fish come to feed on these small fish that hide in the wreckage. Eventually, the largest animals are attracted to the rich life on the shipwreck.
Shipwrecks give us valuable information about how sea plants and animals develop. We know exactly how long this wreck has been under water and how long sea life has been growing on it. Yet even the strongest steel shipwreck will finally be destroyed by the flows of water. But long after this wreck has been broken apart, it will still act as a reef (礁石). Layer upon layer of sea life has formed a structure that is now more natural than artificial, and will remain an island of life under the sea.
小題1:Which of the following is NOT TRUE about shipwrecks?
A.Most ships in ancient times sank easily and become shipwrecks.
B.Shipwrecks, for scientists, are worth researching to get valuable information.
C.The skeletons of old wooden shipwrecks will exist for quite a long time.
D.Some sea animals tend to seek food on the shipwrecks.
小題2:The writer’s purpose in writing the article is to tell us_____.
A.the differences between the ancient vessels and the modern ones
B.how the ships become shipwrecks at sea
C.how coral polyps live on the wreck in warm waters
D.the value of studying shipwrecks at the bottom of the sea
小題3:Which of the following is closer to the underlined “crust”?
A.a(chǎn) hard outer coveringB.the skin of a rock
C.a(chǎn) hole in a shipD.a(chǎn) small house
小題4:What will happen to shipwrecks in the end?
A.They will be pulled out of the sea for research.
B.They are likely to disappear and form reefs.
C.They will become an island under the sea.
D.They will be like works of art.

Every year, British newspapers report on the stranger questions asked in Oxbridge (Oxford & Cambridge) interviews. Often, though, these questions are not as strange as they first seem. And they are all designed to give applicants (申請者) a chance to think.
Arriving for her first Oxford interview, my sister Jen saw that there was only one chair in the waiting room. On the chair was a large fork. Jen had heard about the strange things in Oxbridge interviews, and believed that this was a test. “What if they’re watching me?” she thought. “If I move the fork, it will show initiative (主動(dòng)性); if I don’t move it, it will show that I can easily fit into new situations.” In the end, she sat uncomfortably on the edge of the chair!
Applicants must be prepared for the unexpected. Now it was Jen’s turn. She was handed a monkey skull (顱骨) and asked to talk about it. At first, this seemed unfair --- what could she say? But she soon calmed down, started thinking, and found that there was plenty to talk about.
Oxbridge interviews are designed to find out how you think, not just what you think. And there are no wrong answers. Jen learnt that, and she passed the interview. What advice does she give? “ Don’t be nervous, and be prepared for the unexpected!”
小題1:According to British newspapers, questions for Oxbridge applicants are very _____. 
A.unfairB.normalC.easyD.strange

When your toothbrush is at the end of its days, don’t just throw it away, as a survey has revealed many other uses for an old toothbrush.
The survey was carried out by the Dental Health Foundation to promote National Smile Month and more than 1, 000 people participated in the survey. It found that more than four in every five people re-use their toothbrush for another purpose.
Four in ten people use an old toothbrush to brush bathroom tiles (瓷磚), and almost a third use it to clean kitchen appliances. More than a quarter of those questioned use old toothbrushes to clean jewellery, and roughly one in every five use them for shining shoes. Some other uses for toothbrushes include cleaning bikes, computer keyboards, toilet seats, fish tanks and finger nails.
The survey also found that the age of the owner can determine what happens to a toothbrush after it is not suitable to be used to brush teeth any more. People over 75 are three times more likely to re-use their toothbrush for a different purpose than those between the ages of 16 and 34 and twice more likely than those between 35 and 44.
Additionally,           to reuse their toothbrush for chores (日,嵤) and other uses than their male counterparts. Some women admitted to using their toothbrush to apply hair dye (染料)while some men said they used an old toothbrush to clean their dog’s teeth.
Chief Executive of the British Dental Health Foundation, Dr Nigel Carter, said, “We all should get through around four toothbrushes every year if we are to keep our oral health in great condition. Generally people don’t change their toothbrushes often enough, but there are still plenty of toothbrushes
lying around the house. Our survey has shown that people have realized that a toothbrush is of great value and has a role to play beyond its normal use.”

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag may feel extremely tired for several days. They may also have problems thinking clearly and remembering.
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.
The researcher took some saliva from the women”s mouths to measure levels of a hormone(荷爾蒙) that increases during stress(緊張). He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain”s temporal lobes(腦葉).
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently (永久性的) affect memory.
小題1:According to the text, jet lag .
  1. can cause difficulties in speaking
  2. can make people feel tired for a few weeks
  3. can be only found in flight attendants
  4. can be caused by flying over several time zones
小題2:It can be inferred from the text that .
  1. the conclusion is refused by many scientists
  2. scientists fear that this research is not done properly
  3. the scientific conclusion needs the support from many tests
  4. every women who were examined in the research were mot healthy
小題3:From the result of the research we can see that .
  1. the women who have longer rest at home show better memory
  2. the women who fly in short time have smaller right temporal lobes
  3. the women who have longer flights fail the memory test
  4. the women who rest more than 14 days produce less hormones
小題4:What is the subject discussed in the text?
  1. The cause of jet lag.
  2. A story of a group of flight attendants.
  3. The importance of having enough rest after flights.
  4. A research about the effects of jet lag on the brain.
