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(果蠅), as they share many genes(基因)with humans. The fruit flies were either fed normally or had an apple extract(濃縮物) 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(抗氧化劑) in the apple extract helped clean up dangerous chemicals(化學物質) 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(遺傳密碼) 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.
T
he 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.
【小題1】Why were fruit flies used for the research?
| A．Because they have a similar diet to humans. |
| B．Because they have a history as long as apples. |
| C．Because they share a lot of genes with humans. |
| D．Because they feed on nothing but apple extract. |
A．Apples produce chemicals that can change hu man 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. |
| A．Their genes stopped their development as the environment got worse. |
| B．Their genes became twice in number but they finally died off like dinosaurs. |
| C．They experienced a great genetic change making them used to worse conditions. |
| D．They went through a similar development to peaches, strawberries and other related fruits. |
| A．Eating apples may bring us more advantages than we might believe before. |
| B．People who have the habit of eating apples don’t need to see a doctor. |
| C．Apples that kill the desire to eat are already available in supermarkets now. |
| D．People will eat apples instead of peaches and strawberries from now on. |
If the rose can be said to be a special flower, then the apple can be said to be a special fruit. It is very important in American culture. American stories speak of Johnny Appleseed, who went throughout America collecting apple seeds and planting apple trees. He had a great love for nature and went through fields and farms adding richness and beauty to the country.
One of the first sayings taught to school children is, “An apple a day keeps the doctor away.” This short saying encourages children to eat fresh fruit to keep healthy. If someone always says good words to a person, people will call him an “apple polisher”. This, however, is not a good name. If someone is very dear to us, we say that he or she is the “apple of our eye”.
Most people believe that the fruit which Eve gave to Adam was an apple, even though the Bible(圣經) never says so. The apple, therefore, is a deep part of the language and stories of America.
An apple is also delicious. Apples can be cooked in many ways, used as a dessert, and made into sweet juice.
In many parts of the country during the harvest season, a popular activity is to go into an apple garden to pick apples. Washington, D. C. and New York are both famous for their apples.
Finally, when it’s time to take a vacation to American cities, one can always visit New York, which is “the biggest apple” of all the American cities.
【小題1】What does the underlined phrase “apple polisher” mean?
| A．Something for cutting apples. |
| B．A person who likes to please others. |
| C．A person who is dealing with fruits. |
| D．A machine for cleaning apples quickly. |
| A．Apples are medicine. |
| B．Apples are the most important food. |
| C．New York is famous for its big apples. |
| D．The Bible says Adam was given an apple. |
| A．stories about the apple |
