On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save more people from several illnesses.
Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technology (技术) wasn’t limited (限制) in use.

Like many lovers of books, Mary and her husband, Richard Goldman, seldom walked past a bookstore without stopping to look inside. They often talked of opening their own store one day.
When Mary was in hospital with heart trouble in 1989, they decided it was time to get serious. Richard, who worked for a business company, wanted to work for himself, and Mary needed to slow down from her job.
They started by talking to bookstore owners and researching(调查) the industry. “We knew it had to be a specialty store because we couldn’t match the big chains dollar for dollar,” says Mary. One figure caught her attention: She’d read somewhere that roughly 20 percent of books sold were mysteries(推理小说), and many buyers spent more than $300 a year on books. She and Richard were themselves mystery readers.
On Halloween 1992, they opened the Mystery Lovers Bookshop and Café near their home. With three children in college, the couple could not spend all the family’s money to start a shop. To cover the whole $ 100, 000 cost, they drew some of their savings, borrowed from relatives and from a bank.
The store broke even in its first year, with only $ 120,000 in sales. But Mary was always coming up with new ways to attract customers. The shop had a coffee bar and it offered gifts to mystery lovers and served dinners for book clubs that met in the store. She also invited dozens of writers to discuss their stories.
Today Mystery Lovers makes sales of about $ 420,000 a year. After paying taxes, business costs and the six part-time sales clerks, Richard and Mary together earn about $ 34,000.
“The job you love may not go hand in hand with a million-dollar income,” says Richard. “This has always been about an enjoyable life for ourselves, not about making a lot of money.”

3.According to Richard, the main purpose(目的) of running the bookstore is _________.

A man came home from work late, tired, to find his 5-year-old son waiting for him at the door.
“Daddy, how much money do you make each hour?”
“If you must know, I make $20 each hour.”
“Oh,” the little boy answered, with his head down. He thought for a moment, looked up and said, “Daddy, could you lend me $10?”
The father was furious, “If you asked for the money to buy a toy or some other rubbish, then go straight to your room and think about why you are so selfish!”
The little boy went to his room with no words and shut the door. After a short while, the father calmed down, and started to think, “Maybe he really needs to buy something and he didn’t really ask for money very often.” So he went to the little boy’s room.
“Sorry！Maybe I was too hard on you just now.” said the man, “Here’s $10.”
“Oh, thank you Daddy!” he said happily. Then the boy took out some coins. When the father found that the boy already had money, he got angry again.
“Why do you want more money since you already have some?” the father shouted angrily.
“Because I didn’t have enough, but now I do.” the little boy replied, “Daddy, I have $20 now. Can I buy one hour of your time? Please come home early tomorrow. I would like to have dinner with you.”
