Whatever our differences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic（遗传的）structure with the simple worm.
But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome（染色体组.
To help them do this, they turned to the worm. The nematode（线虫类的）worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better.
What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up.
Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.

A lot of management training each year for Circle K Corporation, a national chain of convenience stores. Among the topics we address in our course is the retention（保护力） of quality employees-a real challenge to managers when you consider the pay scale（标准）in the service industry. During these discussions, I ask the participants（参加者）, “What has caused you to stay long enough to become a manager?” Some time back a new manager took the question and slowly, with her voice almost breaking, said, “It was a ＄19 baseball glove.”
Cynthia told the group that she originally took a Circle K clerk job as an interim（临时的） position while she looked for something better. On her second or third day behind the counter, she received a phone call from her nine-year-old son, Jessie. He needed a baseball glove for Little League. She explained that as a single mother, money was very tight, and her first check would have to go for paying bills. Perhaps she could buy his baseball glove with her second or third check. When Cynthia arrived for work the next morning, Patricia, the store manager, asked her to come to the small room in the back of the store that served as an office. Cynthia wondered if she had done something wrong or left some part of her job incomplete from the day before. She was concerned and confused.
Patricia handed her a box. “I overheard you talking to your son yesterday,” she said, “and I know that it is hard to explain things to kids. This is a baseball glove for Jessie because he may not understand how important he is, even though you have to pay bills before you can buy gloves. You know we can’t pay good people like you as much as we would like to; but we do care, and I want you to know you are important to us.”
The thoughtfulness, empathy and love of this convenience store manager demonstrates vividly that people remember more how much an employer cares than how much the employer pays. An important lesson for the price of a Little League baseball glove.

Although women lead healthier, longer lives, the cruel perception that they reach their sell-by date and become “old” sooner than men is widespread in the workplace, research shows.
A survey of more than 2,600 managers and personnel professionals showed that age discrimination is not only common in the workplace, but is full of inconsistencies(矛盾). Six in ten managers thought that they had suffered from age discrimination——usually because they were turned down for a job for being too old or too young. Yet more than a fifth admitted that they used age as a condition when they employ new workers.
Although the survey found widespread agreement that older workers were better than younger colleagues when it came to reliability, commitment, loyalty and customer service, these qualities were not necessarily considered to be worthy of advancement. More than half of respondents believed that workers between 30 and 39 were the most likely to be advanced in their company, with only 2 per cent citing (引证)50-year-olds or above.
Dianah Worman of the Chartered Institute of Personnel and Development said that there was anecdotal evidence that people were considered old at different ages in different sectors. “We heard of one man working in IT who said he was considered too old by the age of 28,”she said.“There was no evidence to suggest that older workers were less valuable to companies than younger workers, in fact the opposite was often true because older workers often brought experience.” she added.
The findings also suggested that the Government’s ideas on age in the workforce may also be out of step with reality.

A. the age when they retire

Well before the 15th century, an Anglo-Saxon custom required that a prospective bridegroom break some highly valued personal belonging. Half of the broken token was held by the father of the bride and the other half by the groom. A wealthy man was expected to split a piece of gold or silver.
The earliest engagement rings were also used as wedding rings, serving to seal an act of sale which transformed ownership of a daughter from father to husband. Such rings were usually of solid gold to prove the groom’s worth.
For Roman Catholics, the engagement ring became a required statement of Nuptial intent（结婚意向）, as decreed by Pope Nicholas I in 860 A.D. The engagement ring was to be of valued metal, preferably gold, which for the husband-to-be represented a financial sacrifice.
Signifying enduring love, and chosen for its durability, the diamond was chosen for the engagement ring. The diamond’s fire is also associated with “love’s clear flame,” given by Medieval Italians because of their belief that the diamond was created from the flames of love.
The Venetians were the first to discover that the diamond is one of the hardest, most enduring substances in nature, and fine cutting and polishing releases the brilliance. Rarity and cost limited their rapid proliferation（急增） throughout Europe but their intrinsic（内在的） appeal guaranteed them a future. By the 17th century, the diamond ring had become the most sought after statement of European engagement.

A. in the 15th century B. over 1,000 years ago
C .in the 1860s D. by the 17th century

A. Rings made of goldB. Rings made of silver

Fear and its companion pain are two of the most useful things that man and animals possess if they are used. If fire didn’t hurt when it burned, children would play with it until their hands were burned away. Similarly, if pain existed but fear didn’t, a child could burn itself again and again because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier—and some do exist—is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which man and animals might soon die out.
In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. The important thing is not to let fear rule you, but instead, to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.
In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well.
In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing into your house, and you may not want to go and live in a desert where there are no airplanes. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of the particular danger is no longer of any use to you, and you have to try to overcome it.

A. Too much fear is harmful B. Fear is always something helpful
C .Fear is something that can be avoided
D. Fear ought to be used as our guide in our life
4.The best title for this passage should be __________.
A. No Pains, No Gains B. Pain and Actions
