WARMING UP
Answers:
1 Archimedes, Ancient Greek (287-21
2 BC) He was a mathematician. He found that if you put an object into water the water pushes the object up. It rises and partly floats. The force of the water pushing it up is the same as the weight of the object.
2 Charles Darwin, British (1808-1882) The Origin of Species was published in 1859. It explained how plants and animals had changed over time to fit in with a changing environment. At the time it was published it was very controversial. Many people believed the Bible when it said that God made the first two people (Adam and Eve) and that all other people came from these two. Darwin’s book showed that people had developed from apes instead. So this caused a lot of argument between religious and scientific people. However Darwin’s idea became very influential and is still accepted today.
3 Thomas Newcomen, British (1663-1729) He improved the first steam pump built by Thomas Savery in 1698 and turned it into a steam engine for taking water out of mines in 1712. James Watt improved it still further in the 1770s turning it into the first modern steam engine used on the railways.
4 Gregor Mendel, Czech (1822-1884) He grew pea plants and developed ideas on heredity and inherited characteristics. He concentrated on cross-fertilising pea plants and analyzing the results. Between 1856-1863 he grew 28,000 pea plants. He examined seven kinds of seed and plant characteristics and developed some laws of inheritance. The first is that inheritance factors do not combine but are passed to the next generation intact. Second, he found that each partner gives half the inherited factors to the young. Third, some of these factors show up in the offspring (and so are dominant). The other factors are masked by the dominant ones (and so are recessive).
5 Marie Curie, Polish and French (1867-1934) She was born in Poland and came to study in France in 1891 and she lived there for the rest of her life. In 1898 she discovered radium. She received two Nobel prizes, one (with Pierre Curie) for physics (1903) and one for chemistry (1911). She is the only person to have been so honoured. On the death of her husband she took over his job at the Sorbonne in Paris. Her work on radioactivity and the discovery of radium meant that she began a new scientific area of research. She was the first woman to receive a Nobel Prize and the first woman to teach at the Sorbonne.
6 Thomas Edison, American (1847-1931) He was already an inventor of other electrical devices (phonograph, electric light bulb) when in 1882 he designed a system for providing New York with electricity from a central power station. This was a tremendous achievement, which had previously been thought impossible.
7 Leonardo da Vinci, Italian (1452-1519) He was a famous artist whose skill for showing human skin tones made his paintings seem to come alive. He used to study dead people in order to make his paintings as accurate as possibile. Some of his famous paintings include “The Adoration of the Magi” and
the “The Last Supper”. Later in his life he lived in France where he designed a submarine and a flying machine.
8 Sir Humphry Davy, British (1778-1829) He did research into different gases and discovered the medicinal value of nitrous oxide (or laughing gas) as an anaesthetic. In 1815 he developed a safety lamp for miners. Previously there had been many accidents when candles on the mi ners’ helmets had exploded when it came into contact with underground gas from the coal the miners were digging. The safety helmet made working underground very much safer.
9 Zhang Heng, Chinese (78-139) He invented the first seismograph to indicate in the direction of an earthquake. It was in the shape of a cylinder with eight dragon heads round the top, each with a ball in its mouth. Around the bottom were eight frogs directly under a dragon’s head. When an earthquake occurred, a ball fell out of the drag on’s mouth, making a noise.
10 Stephen Hawking, British (1942-) He has worked in astronomy and studied black holes in space. He has shown that black holes do not only absorb everything around them but, from time to time, throw out matter as well. This may mark the beginning of new galaxies. This is an advance on the old theory which said that black holes “eat” everything they come across. COMPREHENDING
Answer key for Exercise 1:
1 An outbreak of cholera hit London in 1854.
2 John Snow began to test two theories.
3 John Snow investigated two streets where the outbreak was very severe.
4 John Snow marked the deaths on a map.
5 He found that most of the deaths were near a water pump.
6 He had the handle removed from the water pump.
7 He announced that the water carried the disease.
8 King Cholera was defeated.
Answer key for Exercise 2:
1 John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.
2 No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.
3 Three diseases, which are similar today, are SARS, AIDS and bird flu, because they are serious, have an unknown cause and need public health care to solve them. Sample summary for Exercise 3:
John Snow wanted to find the cause of cholera. He believed that people became ill after eating infected food. He used the next outbreak of cholera to test his idea. He studied a small area of houses which got their water from the same pump. Many people in the area died. John Snow showed that this was because the water in the pump was infected. He showed that cholera could be defeated if people drank clean water.

A GREAT CHINESE SCIENTIST
Father of the Chinese space programme
Yu Ping (YP) is talking to her friend Steve Smith (SS) about Qian Xuesen and his work as a rocket scientist.
Part 1
YP: What do you want to be when you grow up, Steve?
SS:I want to be an astronomer and visits stars. I wish to visit Mars one day.
YP:I think I’d like to work in the space industry too. I’d like to be a rocket scientist like Qian Xuesen.
SS:What did he have to do to become a rocket scientist?
YP:Well, he first studied at university to be
an engineer. Later he went to America to study for his doctor’s degree. It was then he began to work on rockets.
SS:So it was lucky for our space programme that he came back to China.
YP:Very much so. There was no work on space rockets in China before he began his institute to design and build rockets to go into space.
Part 2
SS:Do you think he wanted to travel into space in one of his rockets?
YP:I have no idea but I believe he looked forward to the first space flight by a Chinese astronaut.
SS:Yes. Now that China has sent satellites into space. I hope we’ll be the first to land on Mars. That would really be something special and if I were that astronaut I would put Qian Xuesen’s picture on Mars to show how much we admire his work.
YP:Indeed. He is rightfully called the father of the Chinese space programme. He is my hero and he is why I want to be a rocket scientist.
SS:Well, we’d better get on with our homework. We need good grades to get into university.
YP:Right you are. See you, then.
SS:See you.

Answer key for Exercise 2:
Students give their own answers.
Sample writing:
Dear Nicolaus Copernicus,
I am a student studying astronomy and I would very much like to read your new theory about the solar system. I hope you will publish it for several reasons.
I understand the problems with the present theory. The way the planets move is not what you would expect if the earth was the centre of the universe. It is also odd that the brightness of some stars seems to change. So I agree with you that we need a new theory.
I know your observations have been very carefully carried out over many years. Now you must have the courage to publish them. Science can never advance unless people have the courage of their beliefs. I know you worry about what will happen if you publish your new theory. No matter how people oppose it, time will show whether your ideas are right or wrong.
So I hope you will feel you can publish your new theory.
Yours sincerely,
(your name)

Question 2: It takes ten hours to fly from Beijing to London Heathrow Airport if you take a direct flight.
Question 3:It may appear to an outsider that the Queen has an important role in ruling the country. However, this is not so. Her position is ceremonial: opening Parliament, welcoming Heads from other countries, going on tours to other countries to encourage trade with Britain, etc. The Prime Minister together with his most important ministers (called the Cabinet) and his Members of Parliament (each from a different part of the country) make the important political decisions and the laws. Question 4: The counties of Britain are much smaller than provinces in China. They have local government powers for their area. Counties have several Members of Parliament depending on the size of their population. Large towns such as Reading have two MPs and the largest city in England outside London, which is Birming- ham, has ten MPs.
Question 5: The Rivers Thames and Severn are very similar in length but the River Thames is slightly longer. The River Thames is 338 km and the River Severn is 290 km. The River Avon is much shorter. COMPREHENDING

about the history of the Tower of London from a guide (G).
Part 1
G:The Tower was the home of the King but also a prison. Many important people were kept there.
ZP:I beg your pardon? Can you speak more slowly, please?
G:Of course. Have you heard of “The Princes in the Tower”?
ZP:No, I’m afraid not.
G:These two princes were brothers, called Edward and Richard and they lived six hundred years ago. They came to London, for the older boy to become Edward Ⅴ, after his father, King Edward Ⅳ, died. ZP:I see. How old was he?
G:He was only thirteen years old. His cruel uncle, also called Richard, was supposed to look after them both, but instead he had them killed while they were asleep.
ZP:What do you mean? He killed them himself?
G:No. He sent his men to kill them because he wanted to become King Richard Ⅲ. There is a story that on a dark night you can sometimes hear those princes crying.
ZP:You can hear them crying? Really? I thought you said they were killed many years ago.
G:Yes, but it’s only a story!
Part 2
ZP:Who else came to the Tower as a prisoner?
G:A future queen. In the 1550s Queen Mary sent her sister, Princess Elizabeth, to the Tower as a prisoner.
ZP:Strange! Why did she do that?
G:She thought Elizabeth was a traitor. So she sent Elizabeth through a special gate called “Traitors’ Gate”. That only happen- ed to very bad people.
ZP:I’m sorry I don’t understand. How did Elizabeth become Queen if she was a prisoner?
G:Easy. Her brother and sister both died without children so Elizabeth became Queen Elizabeth Ⅰ. She tried not to be unfair to others when she was queen.
ZP:I’m glad to hear that.

S2:The Emperor came to pray for good crops and a good harvest for the country. He made offerings to the God and asked him for help.
S1:Please can you speak more slowly? I’m afraid I can’t follow you.
S2:I’m sorry. I’ll speak more slowly. This is
the Hall where the Emperor made his sacrifices to the Gods. You may not go in but just look through the door.
S1:What did you mean by making sacrifices? S2:He killed many animals after making prayers. He was also dressed in special clothes.
S1:I beg your pardon? Special clothes! I thought his clothes were always special! What were they?
S2:They were clothes kept just for this occasion. He changed in a special yellow room and came out to go to pray to the Gods.
S1:I see. When did this stop?
S2:When the Emperors stopped ruling China.

LISTENING TEXT
CAN PEOPLE REALLY LIVE ON MARS
LI Qiang(LQ) is interviewing Walker
Hiller(WH) on the space station about his idea for building a new town called “Wonderworld” on Mars.
LQ: Well, Mr Hiller Why did you think of building a new town on Mars?
WH: It sounds astonishing, doesn’t it? I imagine that it’ll be difficult and the atmosphere, gravity, and climate will have to be just like the earth or nobody will travel there.
LQ: Can you imagine how that’ll be achieved?
WH: Yes, I think so. The atmosphere’s too hot and has no oxygen. So people couldn’t breathe Mars’air and live. We’ll make a covered area for people to live in with a special air supply.
LQ: Is it likely you can find and use water to keep the climate similar to that on the earth?
WH: Perhaps. We hope there’s water under the planet’s surface. People will have to collect all the used water so it can be cleaned and recycled as rain. Then it can be used again to water plants and crops and provide clean drinking water.
LQ: Yes. I suppose everyone will have to put their dirty water in special tanks. Even animals will have to be trained to go to the toilet in special places.
WH: Yes, I suppose so.
LQ: So is it likely that bacteria will clean the water?
WH: Well, that’s a possibility.
LQ: I wonder if the houses can be made strong enough against the gravity on Mars? WH: Yes, they can. The robots will provide special building material.
LQ: Still life sounds quite uncomfortable. So what’s the advantage of going to live on Mars?
WH: There will be opportunities for scien- tific work and to look for gold or other metals. So people may become rich or famous.
LQ: How healthy will the people be, I wonder?
Answer key for Exercise 1:
Ticks for: living on another planet, atmos- phere and gravity, how to get water on Mars, houses in a town on Mars
Suggested answers to Exercise 2:
1 “Wonderworld” will provide a covered area for people to live in with a special air supply.
2 “Wonderworld” will make sure there is enough water by collecting some from under the planet’s surface. After use, this water will be cleaned and recycled so that it can be used as rain to water drops and provide clean drinking water. Everyone will put their dirty water in special tanks and animals will have to go to the toilet in special places. Bacteria will clean this dirty water so it can be used again.
3 People may become rich or famous.
4 I think the people will be quite healthy as they have a satisfactory climate, enough water and sufficient accommodation to live comfortably.
