Most people will tell you that they can’t work without a cup of coffee in the morning. Research has shown that a cup of coffee does give a person slight excitement.
Legend said that Kaldi, an Ethiopian, found his goats happier while enjoying coffee plants. Curiously, he tasted the leaves and began to dance around. Whether the Legend was true or not, the discovery of coffee dates back to 800A. D. Soon Arabians were roasting coffee beans. Muslims were drinking coffee to stay awake by 1000 A.D. A merchant from Venice introduced coffee to Europe in 1615. By 1696, the Dutch started growing the coffee bush in Java. By 1723, coffee plants were introduced to the Americans. Today, coffee is the most popular drink in the world.
Caffeine is the major chemical in coffee. It blocks(阻止) adenosine, a chemical that makes you sleepy. People can get a pick-me-up or stimulation(刺激) from the drink. The stimulation does not last long. Caffeine poisoning can occur if more than 400 milligrams of caffeine is drunk in a short period, which is about four to five cups of coffee. Caffeine will also cause sleep difficulty, so it should not be drunk before bed.
Caffeine has many advantages. Studies have shown that it helps improve some skills in elderly women. Women who drank three cups of coffee daily scored higher on memory tests than women who drank one cup of coffee. According to newser.com, one cup of coffee a day protects the brain. Coffee also can help people keep away from many diseases according to webmd.com.
Large amounts of coffee can cause nervousness, worries and a fast heartbeat. However, if you mix coffee with milk, it’s fine. Caffeine can be addictive like any drug. The more you drink, the more you depend on it. For some people, just one cup of coffee a day is OK.

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. When did we first know why we look like other people in our family?
| A．In 1860. | B．In 1953. | C．In 1961. | D．In 2000. |
What did the two scientists first discover in 1961?
A. The “map” of DNA. B. A new illness.
C. The language of DNA. D. A message of DNA.What can we do if we understand some “words” of the language inside the body?
| A．Make people get new jobs. |
| B．Make medicine for illnesses. |
| C．Make maps of human. |
| D．Make people less attractive. |
What do people think about this work?
| A．It can cause good or bad results. |
| B．It can cause only good results. |
| C．It can cause good results but won’t work. |
| D．It can cause only bad results. |
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.” After Mary got well from her illness they began _________.
| A．to study industrial management (工业管理) |
| B．to buy and read more mystery books |
| C．to do market research on book business |
| D．to work harder to save money for the bookstore |
How did their bookstore do in the first year?
| A．They had to borrow money to keep it going. |
| B．They made just enough to cover all the costs. |
| C．They succeeded in earning a lot of money. |
| D．They failed though they worked hard. |
According to Richard, the main purpose(目的) of running the bookstore is _________.
| A．to pay for children’s education |
| B．to get to know more writers |
| C．to set up more bookstores |
| D．to do what they like to do |
