About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green － a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【小题1】The passage is mainly about _____________.

Five thousand years ago, people thought that illnesses were the result of evil living in human bodies. They also believed that gods and superior spirits were punishing people through diseases. The practice of magic and witchcraft (巫术) was popular among many tribes, and charms (符咒) and images of gods to drive away the evil spirits were often used.

People also started using herbal(草药的) medicine and by trial and error (反复试验，不断摸索) learned how to cure stomachaches and fevers. They had a witch doctor in the community. He would treat people with simple herbal medicine and magic. Early medicine was practiced the way north tribal Indians did hundreds of years ago and the way some tribes practice it today.

The ancient Chinese believed that the body was ruled by two forces, which they called “yin” and “yang”. The body would become ill if one force overcame the other and the balance between them was changed. Acupuncture (针刺疗法) was the way to bring back the balance between the two.

Also sand painting was an important part of Navaho medicine. The medicine man paints loosely upon the floor of an earth-covered house, where the ceremony takes place, or on a buckskin (鹿皮) or a piece of cloth, by letting the colored sands flow through his fingers with control and skill.

Ancient Mesopotamians believed that diseases come either from an evil spirit or a physical problem, such as worms. The doctor would decide from which source the illness has come from and send the patient either to a herbalist or to a witch doctor.

Egyptians had a very advanced medicine. They would sometimes rely on the god’s power to receive healing, but they also treated illnesses and operated on minor health problems like snake bites. They sucked the blood from the wound and bound the affected limb to stop the poison from spreading.

It’s great fun to explore(探索) new places—it feels like an adventure,even when you know you’re not the first to have been there.But make sure not to get lost or waste time going round in circles.

●Do the map reading if you’re being driven somewhere.It’ll be easier if you keep turning the map so it follows the direction you’re traveling in.Keep looking ahead so that you can give the driver lots of warning before having to make a turn,or you’ll have to move to the back seat.

●Get a group of friends together and go exploring.You’ll need a good map,a compass(指南针),a raincoat,a cell phone to call for help in case you get lost,and a bit of spare cash for emergencies(应急现金).Tell someone where you’re going before you set out and let them know what time you expect to be back.The test is in not getting lost,not in seeing how fast you can go,so always stick together,waiting for slower friends to catch up.

He has lived through various dangers but time may be running out for the Palestinian leader, Yasser Arafat.
On September 11, Israel announced its decision to remove him, following several Palestinian suicide bomb attacks on Israel. “He should be punished for the killings,” an Israeli official said, “He has done nothing to stop the terrorist groups.”
But the decision has angered many other countries. China said that Arafat is the true leader, elected by the Palestinian people, and removing him would harm the peace in the Middle East. Other governments share this idea.
Arafat himself said: “They can kill me, but never get me out of my country.” He has spent most of his life in danger as the most important aim of Israel. But, just like a cat with nine lives, Arafat escaped every time.
For years he has made a practice of sleeping in a different bed each night, thinking a moving person is harder to hit. In 1985, Israel sent fighter planes to kill Arafat. The wild bombing destroyed his office in Tunis but Arafat himself was unhurt. In 1992, the aircraft in which he was flying over North Africa broke in two during a crash landing. The pilot was killed but he managed to remain alive.
What is so unbelievable is that he always remains calm in great danger. Israeli tanks and planes attacked his office building in Ram Allah in December 2001. When they saw the attackers coming, Arafat’s bodyguards took no notice of his orders to stay still and carried him to safety underground. Seconds later, several bombs were dropped nearby. Though safe, his bodyguards were so frightened that they were wet in sweat.
But, Arafat, with Israeli tanks only 200 meters away, showed no fear at all. He stayed in the damaged office, talking by phone with foreign leaders in hope of preventing further attacks from Israel.
All these experiences have made him a beloved leader to his people and an enemy to some others.
But has he used up the last of his nine lives? Only time will tell.
【小题1】.   According to the passage, which statement is true?

A．Arafat is as clever as a cat.

B．Arafat can live as long as a cat.

C．Arafat can stay alive after accidents or disasters as if he has nine lives.

D．Arafat should have died for at least 8 times.

Pop stars today enjoy what once only belonged to the royalty(皇室)．Wherever they go，people turn out in their thousands to greet them.The crowds go wild trying to catch a brief glimpse of their smiling，colorfully dressed idols.The stars are transported in their chauffeur driven Rolls Royces，private helicopters or executive aeroplanes.They are surrounded by a permanent entourage(随从)of managers，press agents and bodyguards.Photographs of them appear regularly in the press and all their comings and goings are reported，for，like royalty，pop stars are news.If they enjoy many of the privileges of royalty，they certainly share many of the inconveniences as well.It is dangerous for them to make unscheduled appearances in public.They must be constantly shielded from the adoring crowds who idolize them.They are no longer private individuals，but public property.The financial rewards they receive for this sacrifice cannot be calculated，for their rates of pay are great.

And why not？Society has always rewarded its top entertainers lavishly.The great days of Hollywood have become legendary：famous stars enjoyed fame，wealth and adulation(奉承)on an all time scale.By today's standards，the excesses of Hollywood do not seem quite so spectacular.A single gramopphone record nowadays may earn much more in royalties than the films of the past ever did.The competition for the title“Top of the Pops”is fierce，but the rewards are truly huge.

It is only right that the stars should be paid in this way.Don't the top men in industry earn enormous salaries for the service they perform to their companies and their countries？Pop stars earn vast sums in foreign currency—often more than large industrial companies—and the taxman can only be grateful for their massive annual contributions to the exchequer(国库)．So who would begrudge them their rewards?

It's all very well for people in boring jobs to complain about the successes and rewards of others.People who make envious remarks should remember that the most famous stars represent only the tip of the iceberg.For every famous star，there are hundreds of others struggling to earn a living.A man working in a steady job and looking forward to a pension at the end of it has no right to expect very high rewards.He has chosen security and peace of mind，so there will always be a limit to what he can earn.But a map who attempts to become a star is taking enormous risks.He knows at the outset that only a handful of competitors ever get to the very top.He knows that years of concentrated effort may be rewarded with complete failure.But he knows，too，that the rewards for success are very high indeed：they are the payback for the huge risks involved and once he makes it，he will certainly earn them.That's the essence of private enterprise.
