It’s 2035. You have a job, a family and you’re more than 40 years old. Welcome to your future life.
Getting ready for work, you pause in front of the mirror, “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics(智能电子元件) are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe that you are 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You’re not even middle-aged.
As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear: “To lose weight, you shouldn’t eat that,” from your shoes. They read the tiny electronic code(电子源码) on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible food appears on the counter as kitchen checks its food supplies.
“Ready for your trip to space?” You ask your son and daughter. In 2005 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trips or longer vacation. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical advances, vaccination shots(防疫针) are a thing of past. Ordinary foods contain specific vaccines. With the berries in their mouths, the kids head for the front door.
It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office, Autopilot,” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.
1. What changes the color of your shirt? ____.
A. The mirror B. The shirt itself
C. The counter D. The medicine
2. How do the shoes know that you shouldn’t eat the breakfast cereal?
____.
A. By pouring the breakfast into a bowl
B. By listening to the doctor’s advice
C. By testing the food supplies in the kitchen
D. By checking the nutrition details of the food
3. The strawberries the children eat serve as ____.
A. breakfast B. lunch C. vaccine D. nutrition

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruit and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provision to supply the missing vitamins.
An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”, which used to make large numbers of Eastern peoples who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted(传播) by a germ(病菌). He was working in a Japanese hospital, where the patients were fed on polished rice which had the outer coverings removed from the grain. It was thought this would be easier for weak and sick people to digest.
Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’ plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coveringseven though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice(糙米) somehow prevented or cured beri-beri—even that a lack of some ingredients (成分) in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards isolated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

A. is suitable for losing weight
B. should be only fruits and vegetables

Science Daily (Apr. 27, 2008) —Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean(地下的) and aboveground herbivorous(食草的) insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. This way, aboveground insects are warned that the plant is already “occupied”.
Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant, which warn the aboveground insects about their presence. This messaging makes it possible for spatially-separated insects to avoid each other, so that they do not compete for the same plant.
In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean residents and vice versa(反之亦然). It seems that a system has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. This avoids unnecessary competition.
Through the “green telephone lines”, subterranean insects can also communicate with a third party, namely the natural enemy of caterpillars(毛虫). Parasitic wasps lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more insects for their eggs. The communication between subterranean and aboveground insects has only been studied in a few systems. It is still not clear how widespread this phenomenon is.
This research was carried out at the Netherlands Institute for Ecology (NIOO-KNAW) by Roxina Soler, Jeffrey Harvey, Martijn Bezemer, Wim van der Putten and Louise Vet. The PhD project, in which this study was carried out, was funded by the Free Competition of NWO Earth and Life Sciences.

A. send out warning signals B. choose to leave the plant
C. compete for the same plant D. fight with the root-eating insects

A. have more green leaves
B. have more subterranean leaves
C. are often visited by parasitic wasps
D. are not occupied by root-eating insects

What happens when human beings are not allowed to sleep for long periods of time? To answer this question, a New Yorker, offered to stay awake for 200 hours. During that time, Tripp was observed by a group of doctors, who reported on his progress.
After three days of staying awake, he began to show signs of his mental breakdown. He laughed at things that were not funny, and wept at things that were not sad. Complaining of pressure caused by a hat on his head, he tried repeatedly to take it off. Tripp, of course, was not wearing a hat.
On the fifth day he cried out that a doctor’s jacket looked like crawling worms. Then he imagined he was in another city; he tried to run away from the building, insisting it was on fire; he thought the 200 hours without sleep, Tripp, told the doctors, was“suffering from mental illness”. He was nearly mad.
Barely able to stand, Tripp was helped to cross the street to a room in a hotel. There, after being awake for 201 hours and thirteen minutes, he fell asleep. The doctors predicted he would sleep for twenty or thirty hours. “Peter Tripp will sleep the deepest sleep in history,” said the doctors. Tripp slept all right for nine hours and eleven minutes. When he awoke, his first words were:“I feel fine”. After a medical check, his greatly surprised watchers pronounced him fit.
1. The best title for this passage is ____.
A. Adjusting to Sleeplessness
B. Threat and Danger to Health
C. Test of the Strength to Health of Body and Mind

Researchers in the United States say dust clouds from dry African deserts may be a threat (威胁) to the environment and human health. They say the dust may contain many small organisms that could be dangerous to some people.
Each year, huge dust storms form in the Sahara and Sahel deserts of northern Africa. Winds carry the dust across the Atlantic Ocean. The movement of dust across the Atlantic Ocean has been increasing in recent years because of longer periods without rain in Africa.
From February to April, the dust settles in South America. From June to October, the winds change and transport the dust to North America, Central America and the Caribbean. The dust clouds travel several thousand meters above sea level. It takes five to seven days for the dust to cross the Atlantic Ocean.
Researchers have long known that the dust clouds could travel long distances. But they thought few microorganisms could survive the trip because of damaging ultraviolet radiation(紫外线) from the sun. Researchers now believe that the dust clouds block enough of the light to protect viruses, bacteria, and fungi (真菌) in the dust.
Researchers say these microorganisms may be a health risk to some people. About half of the bacteria and fungi that survive the trip from Africa are known to cause disease in people or plants.
More than half of the dust that reaches the United States settles in the state of Florida. For many years, it has caused the skies there to turn red. Now researchers say there may be a link between the dust storms and increased health risks in Florida. They believe the dust causes higher rates of asthma (哮喘), allergies (过敏) and other breathing problems in people there. The dust also has been linked to a large increase in lung problems in at least one Caribbean nation.
Last year. American scientists published a study showing that the African dust is causing coral reef (珊瑚礁) damage in the Caribbean. They recognized the organisms in the dust particles(微粒) causing coral diseases.
1. Which statement about African dust storms is TRUE? ____.
A They form in the north of Africa and move eastwards
B. They form in the north of Africa and move westwards
C. They settle in South Africa from February to April
D. It takes over a week for them to cross the Atlantic Ocean
2. What does the underlined word “microorganism” mean? ____.
A. Germ
B. Microscope
C. Animal
D. A living creature too tiny to be seen
3. The worst thing about African dust storms is ____.
A. the heat they give off B. the distance they cover
C. the microorganisms they contain D. the time they last
4. The best title for this text is ____.
A. How African Dust Storms Form
B. Dust and Environment
C. Dust and Health
D. African Dust Storms Threatening Human Beings

Science Daily (Apr. 27, 2008) —Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean(地下的) and aboveground herbivorous(食草的) insects can communicate with each other by using plants as telephones.

Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects.

What happens when human beings are not allowed to sleep for long periods of time? To answer this question, a New Yorker, offered to stay awake for 200 hours. During that time, Tripp was observed by a group of doctors, who reported on his progress.
After three days of staying awake, he began to show signs of his mental breakdown. He laughed at things that were not funny, and wept at things that were not sad. Complaining of pressure caused by a hat on his head, he tried repeatedly to take it off. Tripp, of course, was not wearing a hat.
On the fifth day he cried out that a doctor’s jacket looked like crawling worms. Then he imagined he was in another city; he tried to run away from the building, insisting it was on fire; he thought the 200 hours without sleep, Tripp, told the doctors, was“suffering from mental illness”. He was nearly mad.
Barely able to stand, Tripp was helped to cross the street to a room in a hotel. There, after being awake for 201 hours and thirteen minutes, he fell asleep. The doctors predicted he would sleep for twenty or thirty hours. “Peter Tripp will sleep the deepest sleep in history,” said the doctors. Tripp slept all right for nine hours and eleven minutes. When he awoke, his first words were:“I feel fine”. After a medical check, his greatly surprised watchers pronounced him fit.

Researchers in the United States say dust clouds from dry African deserts may be a threat (威胁) to the environment and human health. They say the dust may contain many small organisms that could be dangerous to some people.
Each year, huge dust storms form in the Sahara and Sahel deserts of northern Africa. Winds carry the dust across the Atlantic Ocean. The movement of dust across the Atlantic Ocean has been increasing in recent years because of longer periods without rain in Africa.
From February to April, the dust settles in South America. From June to October, the winds change and transport the dust to North America, Central America and the Caribbean. The dust clouds travel several thousand meters above sea level. It takes five to seven days for the dust to cross the Atlantic Ocean.
Researchers have long known that the dust clouds could travel long distances. But they thought few microorganisms could survive the trip because of damaging ultraviolet radiation(紫外线) from the sun. Researchers now believe that the dust clouds block enough of the light to protect viruses, bacteria, and fungi (真菌) in the dust.
Researchers say these microorganisms may be a health risk to some people. About half of the bacteria and fungi that survive the trip from Africa are known to cause disease in people or plants.
More than half of the dust that reaches the United States settles in the state of Florida. For many years, it has caused the skies there to turn red. Now researchers say there may be a link between the dust storms and increased health risks in Florida. They believe the dust causes higher rates of asthma (哮喘), allergies (过敏) and other breathing problems in people there. The dust also has been linked to a large increase in lung problems in at least one Caribbean nation.
Last year. American scientists published a study showing that the African dust is causing coral reef (珊瑚礁) damage in the Caribbean. They recognized the organisms in the dust particles(微粒) causing coral diseases.
1. Which statement about African dust storms is TRUE? ____.
A They form in the north of Africa and move eastwards
B. They form in the north of Africa and move westwards
C. They settle in South Africa from February to April
D. It takes over a week for them to cross the Atlantic Ocean
2. What does the underlined word “microorganism” mean? ____.
A. Germ
B. Microscope
C. Animal
D. A living creature too tiny to be seen
3. The worst thing about African dust storms is ____.
A. the heat they give off B. the distance they cover
C. the microorganisms they contain D. the time they last
4. The best title for this text is ____.
A. How African Dust Storms Form
B. Dust and Environment
C. Dust and Health
D. African Dust Storms Threatening Human Beings
