Asked to name their favorite city, many Amerians would select San Francisco began as a small Spanish outpost located on a magnificent bay.The town was little more than a village serving ranchers when the United States took possession of it in 1846 during the war with Mexico.
San Francisco sprang into a city overnight because of the nearby discovery of gold in 1848.A great rush to California took place.Wagon trains plodded their dangerous way across 2000 miles of prairie and mountains,while hundreds of sailing vessels made the equally hazardous trip around the Horn.The vessels disgorged thousands of passengers -- then the crews deserted teir ship and hundreds of vessels were left to rot in the bay.Within two years,California had enough population to become a state and San Francisco was for many years the hub of that newly-arrived population.
The city's present popularity is due to an excellent climate, an easy style of living ,good food,and numerous tourist attractions. The city is famous for its cable cars which \seafood stals along the wharf. Most visitors arriving from nations in the Pacific Basin spend several days getting to know the town.

Most young people enjoy some form of physical activity.It may be walking, cycling or swimming,or in winter,skating or skiing.It may be game of some kind football,hockey,golf,or tennis.It may be mountaineering.
Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment.Why are men and women willing to suffer cold and hardship,and to take risks on high mountains? This astonsihment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.
Mountaineering is a sport and not a game.There are no man-made rules,as there are for such games as golf and football.There are , of course,rules of adifferent kind which it would be dangerous to ignore,but it is this freedom from man-made rules that makes mountaineering attractive to many people.Those who climb mountains are free to use their own methods.
If we compare mountaineering and other more familiar sports,we might think that one big difference is that mountaineering is not a 'team game'. We should be mistaken in this. There are ,it is true, no 'matches' between 'teams' of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend,there is obviously teamwork.
The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport tequires high mental and physical qualities.
A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty,and most international tennis champions are in their early twenties.But it is not unusual for man of fifty or sixty to climb the highest mountains in Alps.They may take more time than younger men, but they probably climb with more skill and less waste of effort,and their certianly experience equal enjoyment.
1.Mountaineering involves____. a.cold b.hardship c.physical risk d.all of the above
2.The difference between a sport and a game has to do with the kind of _____. a.activity b.rules c.uniform d.participants
3.Mountaineering can be called a team sport because_____. a.it is an Olympic event
b.teams compete against each other
c.mountaineers depend on other while climbing d.there are 5 climbers on each team
4.Mountaineers compete against______. a.nature b.each other c.other teams
d.international standards
5.Choose the best title for the passage_______. a.mountaineering is different from golf and football b.mountaineering is more attractive than other sports c.mountaineering d.mountain climbers

第30篇
No one knows exactly how many disabled people there are in the world,but estimates suggest the figure is over 450million. The number of disabled people in India alone is probably more than double the total population of Canada.
In the united Kingdom,about one in ten people have some
disability.Disability is not just something tht happens to other people:as we get older,many of us will become less mobile,hard of hearing or have failing eyesight.
Disablement can take many forms and occur at any time of life.Some people are born with disabilities.Many others become disabled as they get older.There are many progressive disabling diseases.The longer time goes on,the worse they become.Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness.All are affected by people's attitude towards them.
Disabled people face many physical barriers.Next time you go shopping or to work or visit friends,imagine how you would manage if you could not get up steps,or on to buses and trains.How would you cope if you could not see where you were going or could not hear the traffic? But there are other
barriers:prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fuly appreciate what the severely disabled go through,so it is important to draw attention to these barriers and show that it is the individual person and their ability,not their disability,which counts.
1.The first paragraph points out that______. a.there are many disabled people in the world
b.the number of disabled people in India is the greatest c.India has much more disabled people that Canada

b.there are about 10 percent disabled persons in the UK.
c.the whole society should pay due attention to the barriers faced by the disabled people
d.there still exists prejudice against the disabled which results mainly from ignorance
5.It can be concluded from the passage that____. a.we should try our best to prevent disablement

Not all long-distance phone calls are made over phone wires.Today,phone wires are being replaced by fiber optics.Fiber optics make telephoning faster and easier than ever before.
In the past,telephone calls were made mostly over copper wires.Copper wires are heavy and bulky.Fiber optics are flexible,glass fibers.They are no thicker than a human hair.A wire cable is as thick as a man's arm.An optical fiber cable is as thick as a thumb.
Fiber optics transfer sound into light.First,a person speaks into a phone.The sound is changed into electrical impulses.A small laser changes the electrical impulses into coded bursts of light.The light is decoded hack into electrical impulses at the telephone recieving station.Finally,the electrical impulses are changed into sounds again at the receiving telephone.
Optical fibers transimit calls much faster than copper wires can.The laser pulses with light as fast as 90 million times a second.At that speed,every word in a dictionary can be sent through a single fiber in a few seconds.Optical fibers
