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.”

1. 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

2. 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.

3.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

【小题1】 After Mary got well from her illness they began _________.

You are probably familiar with the saying：An apple a day keeps the doctor away. A recent research carried out by the Chinese University of Hong Kong may change the saying:
An apple a day may keep aging away.
The research chose fruit flies(果蝇), as they share many genes(基因)with humans. The fruit flies were either fed normally or had an apple extract(浓缩物) added to their diet.
It turned out that those fruit flies that were given apple extract lived about 55 days—five days longer than the flies that were normally fed. The research group also found it easier for the flies to walk，climb and move about as they aged.
According to the result, the researchers believed that the antioxidants(抗氧化剂) in the apple extract helped clean up dangerous chemicals(化学物质) that cause illnesses，as well as aging.
In another study，researchers examined diets of thousands of women. They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke.
The apples’ genetic code(遗传密码) was discovered recently. It allows scientists to develop nicer and healthier fruits. Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer.
Apples that kill the desire(欲望) to eat could also be produced, with the first“extra-healthy’’apples on supermarket shelves within just four or five years.
The team that keeps studying apple DNA includes 100 scientists from five countries. Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant，which would finally become today’s apple tree, experienced a great genetic change. The number of many of its genes doubled. The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches，strawberries and other related fruits.
【小题1】Why were fruit flies used for the research?

A．Apples produce chemicals that can change human genes.

B．Apples have antioxidants that kill chemicals that cause aging.

C．Apples are rich in vitamins that are needed in humans’bodies.

D．Apples produce chemicals that make apples taste more delicious.
