An Australian man who has been donating his extremely rare kind of blood for 56 years has saved the lives of more than two million babies.
James Harrison has an antibody in his plasma that stops babies dying from Rhesus disease, a form of severe anaemia. He has enabled countless mothers to give birth to healthy babies, including his own daughter, Tracey, who had a healthy son thanks to her father's blood.
Mr. Harrison has been giving blood every few weeks since he was 18 years old and has now racked up a total of 984 donations. When he started donating, his blood was deemed so special that his life was insured for one million Australian dollars.
He was also nicknamed the “man with the golden arm” or the “man in two million”. He said: “I've never thought about stopping. Never.” He made a pledge to be a donor aged 14 after undergoing major chest surgery in which he needed 13 litres of blood. “I was in hospital for three months,” he said. “The blood I received saved my life so I made a pledge to give blood when I was 18.”
Just after he started donating he was found to have the rare and life-saving antibody in his blood. At the time, thousands of babies in Australia were dying each year of Rhesus disease. Other newborns suffered permanent brain damage because of the condition. The disease creates an incompatibility between the mother's blood and her unborn baby's blood. It stems from one having Rh-positive blood and the other Rh-negative.
His blood has since led to the development of a vaccine called Anti-D. After his blood type was discovered, Mr. Harrison volunteered to undergo a series of tests to help develop the Anti-D vaccine. “They insured me for a million dollars so I knew my wife Barbara would be taken care of,” he said. “I wasn't scared. I was glad to help. I had to sign every form going and basically sign my life away.”
Mr. Harrison is Rh-negative and was given injections of Rh-positive blood. It was found his plasma could treat the condition and since then it has been given to hundreds of thousands of women. It has also been given to babies after they are born to stop them developing the disease.
It is estimated he has helped save 2.2 million babies so far. Mr. Harrison is still donating every few weeks now.

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.

Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.

The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.

Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.

Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.

The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.

And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.

Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.

Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.

1.What does the underlined word “it” in the last but one paragraph refer to?

A. wealth                            B. hydrogen                         C. electricity                       D. fuel

2.What is the problem with using hydrogen as energy?

A. It has by-products.

B. It has to be separated from other materials.

C. It will make energy too cheap.

D. It is too far away from us.

3.Why does the author give the example in the last but one paragraph ?

A. To tell us that we produce energy while using hydrogen power.

B. To tell us that hydrogen power does not produce pollution.

C. To show hydrogen power can stop war.

D. To show hydrogen power is cheap.

4.What is the author’s attitude about the future?

A. skeptical                            B. negative              C. indifferent              D. positive

5.What is the passage mainly about?

A. war and energy                                          B. the future of hydrogen as an energy resource

C. the disadvantages of oil                        D. How to end war

Recently a Beijing father sent in a question at an Internet forum (论坛) asking what "PK" meant. "My family has been watching the 'Super Girl' singing competition TV program. My little daughter asked me what 'PK' meant, but I had no idea," explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, "PK" is short for "Player Kill", in which two players fight until one ends the life of the other.
In the case of the "Super Girl" singing competition, "PK" was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students' compositions using Internet jargons (行话) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn't understand.
"My 'GG' came back this summer from college. He told me I've grown up to be a 'PLMM'. He always took me to the 'KPM'," went one composition.
"GG" means Ge Ge (Chinese pinyin for brother). "PLMM" refers to Piao Liang Mei Mei (beautiful girl). "KPM" is short for KFC, Pizza Hut and McDonald's.
Some specialists welcome Internet jargons as a new development in language. If you do not even know what a Kong Long (dinosaur, referring to an ugly looking female) or a Qing Wa (frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!
40. By writing the article, the writer tries to ________.
A. expose some Internet language     B. suggest common Internet language
C. laugh at the Beijing father           D. draw our attention to Internet language
41. What does the writer think about the term "PK"?
A. Fathers can't possibly know it.       B. The daughter should understand it.
C. Online game players may know it.    D. "Super Girl" shouldn't have used it.
42. The examples of the Beijing father and the Tianjin teacher are used to show
that Internet jargons ________.
A. are used not only online                 B. can be understood very well
C. are welcomed by all the people        D. cause trouble to our mother tongue
43. What would be the best title for the passage?
A. A puzzled father                      B. Do you speak Internet-ish?
C. Keep away from Internet-ish       D. Kong Long or Qing Wa?

You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.
Let’s start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle (角度) to the boat. Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat. It needs to be out far enough to catch the wind, but it shouldn’t flap (摆动). It shouldn’t look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.
Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you are tacking, you must always keep the sail inside the boat.
【小题1】What should you consider first while sailing?

A.Sailors’ strength.B.Wave levels.C.Wind directions. D.Size of sails.
【小题2】What does the word “It” underlined in Paragraph 4 refer to?
A.The boat.B.The wind.C.The sail.D.The angle.
【小题3】What do you have to do when sailing against the wind?
A.Move in a straight line.B.Allow the sail to flap.
C.Lower the sail.D.Tack the boat.
【小题4】Where can you probably find the text?
A.In a popular magazine.B.In a tourist guidebook.
C.In a physics textbook.D.In an official report.

From the beginning of human history, wild animals provided food, clothing and sometimes medicine. We may not depend so much on wild animals now. But we hear about them every day. Americans use the names of animals in many ways. Automobile manufacturers (制造商) and gasoline companies especially like to use big cats to sell their products. They like lions, tigers and wildcats. When Americans say wildcat, they usually mean a lynx, an ocelot or a bobcat. All these cats attack quickly and fiercely. So wildcats represent something fast and fierce.
An early American use of the word wildcat was quite different. It was used to describe members of Congress who declared war on Britain in 1812. A magazine of that year said the wildcat congressmen went home. It said they were unable to face the responsibility of having involved their country in an unnecessary war.
Wildcat also has been used as a name for money. At that time, some states permitted banks to make their own money. One bank in the state of Michigan offered paper money with a picture of a wildcat on it. Some banks, however, did not have enough gold to support all the paper money they offered. So the money had little or no value. It was called a wildcat bill or a wildcat bank note.
The banks which offered this money were called wildcat banks. A newspaper of the time said those were the days of wildcat money. It said a man might be rich in the morning and poor by night.
Wildcat then was used for an oil well or gold mine that had almost no oil or gold in it. Dishonest developers would buy such property. Then they would sell it and leave town with the money. The buyers were left with worthless holes in the ground. Today, wildcat oil wells are in areas that are not known to have oil.
【小题1】What is the main idea of the passage?

A.Wildcats and their stories. B.Wildcats and their characters.
C.Varieties of animal species.D.Relationship between animals and humans.
【小题2】From the passage we can know that ______.
A.wildcats represent the state of Michigan.
B.the use of wildcats was not always the same
C.wildcats are the best friend of human beings
D.honest developers never buy wildcat oil wells
【小题3】The underlined words “a lynx, an ocelot or a bobcat”in Paragraph 1 may refer to ______.
A.gasoline companiesB.automobile manufacturers
C.names of wildcatsD.brands of automobile
【小题4】It can be inferred that during the days of wildcat money ______.
A.people couldn’t buy anything with the money
B.people didn’t know how to save money
C.the rich invested too much on oil wells
D.people complained and suffered a lot
