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.

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.

1. Most historians hold that the Chinese invented fireworks in the 9^th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.

2. In May of 1886, a law led John Pemberton, a pharmacist(药剂师), to rewrite the formula(配方) for “Pemberton’s French Wine Coca”, his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated(碳酸) water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world-wide drink came into being.

3. During World WarⅡ, scientists at the University of Birmingham invented the magnetron(磁控管)—an important heat-producing part of the microwave oven. While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels(仁), and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.
【小题1】The right time order of the three inventions should be ________.

You have probably heard it before, most likely from your English teacher. If you want to become a good writer, read good writing. Unluckily, you may not have understood what did good to you and even what you were supposed to get from that experience.
As you start reading a book, poem, or story, do so with no thought at all and the experience will improve your writing. you may not have understood what did good to you and even what you were supposed to get from that experience.
or to learn. As you progress through the work, think about whether it is “easy” reading or not. Do you become so interested in the subject and flow of the writing that you completely forget the person who wrote it, or does the composition sometimes call too much attention to itself through words and phrases that seem out of place or unexpected? The second situation is a chance to learn from the writer’s mistakes. In fact, the reader should not have to worry about how a writer does “his thing” ... he should be able to just enjoy and learn. Every time a word strikes you as poorly chosen, stop to consider why it has this effect. Also, do not spend a lot of time analyzing (分析) the passage but put more efforts in enjoying it from the whole.
Another thing I do, particularly with nonfiction (非小说) books, is to select a part to read as if it is a completely separate work. Once again, read as a common reader rather than a critic (批评家). For learning how words and phrases work together on the most basic level, however, nothing is more suitable than devoting yourself to reading poems. A poet is often trying to put a book’s worth of meaning and feelings into lines, and every side of the work shows a very close attention to craft (工艺).
As you can see, there is no simple way of reading to improve your writing. The key is not to make it boring. Select writers you admire or like most, and enjoy their works as anyone else would. As long as you are reading, you are improving yourself as a writer.
