[00:08.00]READING AND VOCABULARY

[00:10.40]1 Look at the title of the reading passage below.

[00:15.09]Guess what is about.

[00:17.21]The Students Who Asked Questions

[00:20.89]In a hungry world rice is a staple 1 food

[00:25.29]and China is the world's largest producer.

[00:28.73]Rice is also grown in many other Asian countries,

[00:32.88]and in some European countries like Italy

[00:35.90]In the rice-growing world，

[00:38.61]the Chinese scientist,Yuan Longping,is a leading figure.

[00:43.34]Yuan Longping was born and bought up in China.

[00:47.61]As a boy he was educated in many schools and was given the nickname 2,

[00:52.59]"the student who asks questions".

[00:55.72]From an early age he was interested in plants.

[00:59.40]He studied agriculture in college

[01:02.22]and as a young teacher he began experiments in crop breeding.

[01:06.92]He thought that the key to feeding people was to have more rice

[01:11.43]and to produce it more quickly.

[01:14.81]He thought there was only one way to do this --

[01:17.59]by crossing different species 3 of rice plant,

[01:21.31]and then he could produce a new plant

[01:23.17]which could give a higher yield than either of the original plants.

[01:27.85]First Yuan Longping experiment with different types of rice.

[01:33.49]The results of his experiments were published in China in 1966.

[01:39.24]Then he began his search for a special type of rice plant.

[01:44.34]It had to be male.It has to be sterile 4.

[01:48.77]Finally,in 1970 a naturally sterile male rice plant was discovered.

[01:56.15]This was the breakthrough.

[01:58.40]Researchers were brought in from all over China

[02:01.41]to develop the new system.

[02:03.79]The research was supported by the government.

[02:07.48]As a result of Yuan Longping's discoveries

[02:10.60]Chinese rice production rose by 47.5 percent in the 1990's.

[02:16.39]There were other advantages too.

[02:18.96]50 thousand square kilometres of rice fields

[02:22.60]were converted 5 to growing vegetables and other cash crops.

[02:26.20]Following this,Yuan Longping's rice was exported to other countries,

[02:31.53]such as Pakistan and the Philippines.

[02:34.59]In Pakistan rice is the second most important crop after wheat

[02:40.52]and will be grown in many parts of the country.

[02:43.79]The new hybrid 6 rice has been developed

[02:46.79]by the Yuan Longping High-tech 7 Agricultural Company of China.

[02:51.34]It's yield is much greater than the yield of other types of rice

[02:55.38]grown in Pakistan.

[07:29.90]CULTURAL CORNER

[07:32.61]Read the following passage and answer the questions.

[07:36.50]1 How many rockets invented?

[07:40.84]2 What are they used for today?

[07:45.45]Rockets

[07:47.36]Today rockets are very advanced machines

[07:52.22]which we can use to send astronauts into space.

[07:55.68]They are also used in firework displays to celebrate great events,

[08:00.70]such as the end of the Olympic Games

[08:03.35]or the beginning of the new millennium 8 in the year 2000.

[08:07.65]Rockets were probably invented by accident about 2,000 years ago.

[08:13.97]The Chinese had a form of gunpowder 9

[08:17.07]which was put in bamboo tubes

[08:18.92]and thrown into fires to make explosions during festivals.

[08:23.78]Perhaps some of the tubes jumped out of the fire instead of exploding in it.

[08:29.77]The Chinese discovered that the gas escaping from the tube could

[08:33.41]lift it into the air.

[08:35.86]The idea of the rocket was born.

[08:38.68]The first military use of rockets was in 1232.

[08:44.70]The Song Dynasty was at war with the Mongols.

[08:49.38]During the battle of Kaifeng,the Song army shot "arrows of flying fire".

[08:56.09]The tubes were attached to a long stick

[08:59.31]which helped keep the rocket moving in a straight direction.

[09:03.07]Soon the Mongols learned how to make rockets themselves

[09:07.59]and it is possible that they introduced them to Europe.

[09:11.18]Between the13th and 15th centuries

[09:14.80]there were many rocket experiments in England,France and Italy.

[09:19.84]They were used for military purposes.

[09:22.98]One Italian scientist even invented a rocket

[09:27.00]which could travel over the surface of water and hit an enemy ship.

[09:31.56]But not everybody wanted to use rockets in battles.

[09:35.79]Wan 10 Hu,a Chinese government official,invented a flying chair.

[09:42.00]He attached two big kites to the chair,

[09:45.43]and 47 rockets to the kites.

[09:48.52]The rockets were lit,

[09:50.52]there was a huge explosion and clouds of thick smoke.

[09:54.59]When the smoke cleared Wan Hu and his chair had disappeared.

[10:00.06]No one knows what happened.

[10:02.50]Did Wan Hu die in the explosion?

[10:05.51]Or was he carried miles into space,

[10:08.40]becoming the world's first astronaut?

[12:51.77]READING AND VOCABULARY

[12:54.06]2 Read the passage

[12:57.50]and check the items in activity 1 which the writer talks about.

[13:02.54]A Trip Along the Three Gorges

[13:06.11]In August 1996,Peter Hessler,

[13:10.81]a young American teacher of English,

[13:13.19]arrived in the town of Fuling on the Yangtze River.

[13:17.07]He and a colleague were to spend two years there

[13:21.02]teaching English at a teacher training college.

[13:24.54]They were the only foreigners in the town.

[13:27.67]The first semester finished at the end of January

[13:31.73]and they had four weeks off for the Spring Festival.

[13:34.75]They could go anywhere they wished.

[13:37.72]They decided 14 to take a boat downstream.

[13:41.31]We decided to buy tickets for the Jiangyou boat.

[13:46.65]Our colleagues said,"You shouldn't go on those ships.

[13:50.45]They are very crowded.

[13:52.31]They are mainly for goods and people trading along the river.

[13:56.02]They don't stop at the temples and there won't be any other foreigners."

[14:01.35]That sounded fine to me.

[14:03.63]We just had to show our passports and they let us get on the boat.

[14:09.05]We left the docks 15 on a beautiful afternoon.

[14:14.22]The sun was shining brightly

[14:16.37]as we sailed downstream through a hilly region.

[14:20.11]Men rode bamboo rafts along the river's edge and coal boats went past.

[14:26.59]As the sun set we docked 16 at Fengdu.

[14:30.56]We could see the sun setting behind the white pagoda 17.

[14:33.97]It was beautiful.

[14:36.04]We slept through the first gorge 12,which is called the Qutang Gorge.

[14:42.13]The gorge narrows to 350 feet

[14:45.16]as the river rushes through the two-mile-high mountains.

[14:49.77]"Oh,well," my friend said,"at least we have two more left."

[14:54.77]At Wushan we made a detour 18 up the Daning River to see some of the smaller gorges.

[15:02.50]The next day we went through the big gorges on the Yangtze River.

[15:07.13]It was a lovely morning as we went through the Wu Gorge.

[15:11.68]We passed the Xiang River home of Qu Yuan,the 3rd century BC poet.

[15:18.20]There was so much history along the Yangtze River.

[15:21.67]Every rock looked like person or animal,

[15:25.00]every stream that joined the great river carried its legends,

[15:29.28]every hill was heavy with the past.

[15:32.37]As we came out of the third gorge,the Xiling Gorge,

[15:37.49]we sailed into the construction site of the dam.

[15:40.97]All the passengers came on deck.

[15:44.11]We took pictures and pointed 19 at the site,

[15:47.20]but we weren't allowed to get off the boat.

[15:49.97]The Chinese flag was blowing in the wind.

[15:53.06]On a distant mountain was a sign 20-foot characters.

[15:58.11]"Build the Three Gorges Dam,Exploit the Yangtze River," it said.

[16:03.31]Now say why the writer enjoyed the trip.

[20:37.16]CULTURAL CORNER

[20:39.15]Read the passage and answer the questions.

[20:42.54]1 What does Mr McCorquodale like doing when he travels?

[20:48.00]2 Choose any country and imagine you are there.

[20:54.74]Write a short postcard to yourself.

[20:57.70]Postcards to Myself

[21:00.65]In 50 years of travelling

[21:04.25]Colin McCorquodale has visited every country in the world,except three.

[21:10.50]And everywhere he goes,he sends himself a postcard.

[21:15.32]He always chooses a postcard with a beautiful view,

[21:19.97]and sticks on an interesting stamp.

[21:23.10]Usually he writes just a short message to himself.

[21:27.20]His latest one, from the Malvinas islands,reads Good fishing.

[21:33.45]On a wall in his home in London there is a large map of the world.

[21:39.31]There are hundreds of little red pins stuck in it.

[21:43.13]"It's good to get a pin in the map,"says Mr McCorquodale,

[21:48.36]"but I follow the rules.

[21:49.81]I'm allowed to stick one in only if I've been in a place for more than 24 hours."

[21:55.72]Naturally,Mr McCorquodale has his favourite places.

[22:00.81]New Zealand he describes as "wonderful".

[22:04.96]In Europe,Italy is a favourite place.

[22:08.72]"There's a saying in the travel trade that all tourists are ripped 24 off.

[22:13.71]Well,at least the Italians rip 11 you off with a smile."

[22:17.64]Of China he says,

[22:20.00]"This is one country in the world which is completely different.

[22:24.69]There's no European influence.

[22:27.27]It's been around for 6,000 years,yet it's a country of the future."

[22:33.11]Wherever he goes,

[22:35.61]Mr McCorquodale takes with him a photo of his wife,

[22:38.93]a candle,a torch,a shirt with a secret pocket,

[22:43.54]and a pen for writing his postcards.

[22:46.63]So why does he do it?For the postcards or the travel?

[22:51.52]Mr McCorquodale laughs."I do it for the journey," he says.

[22:56.83]"I get a kick of travelling.And all the planning."
