  After the end of the Second World War, the Russians became very interested in the possibility of travelling into space, and they launched (發(fā)射) several rockets which went round the Earth high above the air. To go higher, it is necessary to use a rocket, which will work excellently even when moving in outer space. The first rockets sent up into space carried no crew [(艦船、飛機(jī)等上的)乘務(wù)員]but only scientific instruments (儀器); the next carried animals and when these were brought back safely to earth the Russian scientists were ready to send up a man. They chose Major Yuri Gagarin to be the first pilot.

  Flying a spaceship is not the same as flying an ordinary aircraft. Instead of sitting at the controls, the pilot lies flat upon a couch; and the take-off is mainly automatic (自動(dòng)的), however, the pilot must always be ready in case anything goes wrong. Fortunately, all went well; the Vostok was launched by its powerful motors, and before long it was more than 100 miles up, travelling at a speed of 5 miles a second or 18,000 m.p.h.-faster than any man had travelled before. Gagarin did not feel any sensation of speed, but he could look through the porthole (舷窗) of his pressurized cabin and see the Earth far below, looking like a vast globe instead of a flat plain. He could make out coastlines, rivers, forests, and clouds; he passed over Siberia, and then on to South America.

  Gagarin was busy all the time making scientific measurements. Also, as the Vostok was equipped with radio, he was able to give the scientists on the ground a running commentary (實(shí)況報(bào)道) on everything he saw. Before long the spaceship passed into the Earth’s shadow; when it came out of the shadow again, the horizon (地平線) glowed (發(fā)出光和熱)a brilliant orange colour.

  When Gagarin had been in space for over an hour, he had nearly completed a journey right round the Earth, and it was time to prepare for the landing. This was perhaps the most dangerous part of the whole trip. If he came into the air too quickly, his ship would rub against the air particles, and the ‘friction (摩擦)would make the ship so hot that it would burn up. The speed of the Vostok had to be checked gradually (逐漸地). Again, all went well. The Vostok steadily (平穩(wěn)地)dropped closer and closer to the ground until, when not far from the ground, Gagarin’s cabin was separated from the rest of the rocket. A huge parachute (降落傘) opened, and the cabin, with Gagarin in it, floated (飄,飄浮) gently down to a safe landing.

  To extinguish(熄)different kinds of fires, several types of fire extinguishers(滅火器)have been invented.They must be ready for immediate use when fire breaks out.Most portable(手提式的)kinds operate for less than a minute, so they are useful only on small fires.The law requires ships, trains, buses and planes to carry extinguishers.

  Since fuel, oxygen(氧氣)and heat must be present for fire to exist, one or more of these things must be removed or reduced to extinguish a fire.If the heat is reduced by cooling the material below a certain temperature, the fire goes out.Water is the best cooling material because it is low in cost and easy to get.

  Another method of extinguishing fire is by cutting off the oxygen.This is usually done by covering the fire with sand, steam or some other things.A blanket(毯子)may be used to cover a small fire.

  A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.

  The method that is used to put out a fire depends on the type of fire.Fires have been divided into three classes.Fires in wood, paper, cloth and the like are called C1ass A fires.These materials usually help keep the fire on.Such fires can be stopped most easily by cooling with water.

(1)

If a fire breaks out on a bus, which of the following should be ready there for you to use?

[  ]

Water

[  ]

A.

separating the fire

B.

reducing the heat

C.

removing the fuel

D.

cutting off the oxygen

(3)

In choosing how to put out a fire, we should first be clear about ________

[  ]

A.

when it breaks out

B.

how it comes about

C.

what kind it is

D.

where it takes place

(4)

What would the writer probably discuss in the next paragraph?
