WARNING: Holding a cell phone against your ear or putting it in your pocket may be bad for your health.   

This sentence is a warning that you’d better not put it close to you when a new phone is bought. Apple company, for example, doesn't want IPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's producer, recommends 2.5 centimeters.

(1)If cell phone use can        health problems, the         will be very serious. Americans spend 2.26 trillion minutes chatting on cell phones every year, which brings $109 billion for the wireless businessmen.

Devra Davis, an epidemiologist(皮肤病专家) who has worked for the University of Pittsburgh, has published a book about mobile phone radiation（辐射）"Disconnect." Davis studies how often brain cancer happens during different age groups. She finds a big increase in brain cancer in the 20-to-29 age group and a drop for the older people.

Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.

Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency（电波频率）radiation had destroyed DNA in their brains.

Ms. Davis recommends using wired earphones（有线耳机）or the phone's speaker. (2)Children should send text messages rather than call, she said, and pregnant（怀孕的） women should keep phones away from their bodies.

Have you ever suddenly felt that someone you know was in trouble—and he was? Have you ever dreamed something that came true later? Maybe you have ESP.
ESP stands for（代表） Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here is an example: A woman was doing washing. Suddenly she screamed, “My father is dead!” I saw him sitting in the chair!” Just then. a telegram came. The woman’s father had died of a heart attack. He died sitting in a chair.
There are thousands of stories like this on record. Scientists are studying them to find out what is behind these strange mental messages. Here’s another example—one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, “There’s room for one more.” The man felt the driver was dead, so he ran away. The next day the man was getting on a crowded bus. The bus driver said, “There’s room for one more.” Then the man saw the driver’s face was the same face he had seen in the dream. He wouldn’t get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are lies or coincidences. Others, including some scientists say that ESP is true. From studies of  ESP, we may some day learn more about the human mind.
【小题1】People with ESP may know about ____________

A．someone’s trouble	B．events before they happen

【小题2】 From the passage it can be inferred that ____________.

A．all people have ESP	B．some women or men have ESP

In the West, some people believe that personality can be predicted according to the time of the year the person was bor. From China comes the belief that the year of birth influences one’s personality. In the past century, a new belief ahs arisen: the idea that personality is related to one’s ABO blood type. People with blood type A, for example, are considered more likely to be serious, hard-working, and quiet, while people with blood type O are likely to be popular and outgoing, yet often unable to finish what they start. Though this belief continues to be strong, some people question whether it is true.

The blood-type personality theory(理论) started in Japan in 1927 when Furukawa Takehi noticed personality similarities and differences among his workers. This idea soon went out of fashion, but was brought back by a Japanese television host named Toshitaka Nomi in the 1970s. The belief is still strong in Japan and is increasingly popular in neighboring countries. Some young Koreans have taken to the theory. A recent study showed 76 percent of Koreans aged between13 and 64 believing in the blood-type personality connection. Though most Asians might believe in the blood-type theory, for many it seems harmless and not something to be taken too seriously.

         Is the belief true? The scientists in Asia largely think the belief as a modern-day superstition(迷信). Most studies have failed to find any strong connection between blood and personality. Generally, scientists are against making predictions or important decisions based on this questionable theory.

3.Which of the following is true according to the passage?

         A. Most scientists in Asia don’t believe in the theory.

         B. The blood-type theory began in Japan in the 1970s.

         C. The blood-type personality theory is about blood type.

         D. People don’t change their personality to match the theory.

D. Is it in you mind?

 

Oriole’s Nest
Picky, Picky
Scientists have no idea exactly why birds choose certain objects to build their nests. But scientists know that the main reason birds build nests is to keep their babies safe, warm and healthy.
Baby birds grow faster and are healthier when they are warm. They also learn to fly and leave the nests sooner than birds without warm homes.
What A Yarn (纱)
Yarn is big on an oriole’s shopping list during nest building. Scientists are still trying to work out why so many birds choose white yarn over other colors for nest building.
Scientists think that the white objects remind birds of cotton fluff (绒毛) they find in the wild.
Do It Naturally  
Even though birds can help us recycle some of our junk by using it to build nests, they also need to use lots of natural things. Long grass, dried sticks, spider’s silk and mud are some of the natural ingredients that are good for nests, too.
You can make a collection box of things to leave for birds so they can help themselves. Hang a small plastic box with holes on a tree branch. Fill the box freely with nest building goodies. Hang the box on a tree and watch birds climb on board to pick through the junk to find their treasures.
Warning: Don’t let the birds turn into a tasty treat. Keep your bird station away from places where cats hang out.
For The Birds!
Stop! Don’t throw all that garbage out! Give some to the birds. Look and see how your old junk can help beautify and warm a bird’s new home.
【小题1】The baby birds with warm homes are able to _____.

A．choose right objects	B．leave the nests sooner
C．build good nests	D．learn to fly higher

【小题2】 What can people make for birds to build nests?

A．Holes on the tree.	B．Food out of the rubbish.
C．A warning board.	D．A collection box of things.

【小题3】What can we learn from the passage?

A．Birds build nests to store things.

B．Birds regard white objects as cotton.

C． Birds and humans can help each other.

D．Birds and cats fight against each other.

Even though global warming may have made the weather more mild, many animals are still hibernating（冬眠）. It’s too bad that humans can’t hibernate. In fact we almost did.
Apparently, at times in the past, farmers in France liked a semi-state of human hibernation. So writes Graham Robb, a British scholar who has studied the sleeping habits of the French farmers. As soon as the weather turned cold, people all over the France shut themselves away and practiced the forgotten art of doing nothing at all for months.
In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sleep has changed since the invention of lighting.
When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though. Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours’ continuous sleep is a modern invention.
In the past, without the artificial light, humans went to sleep when it became dark and then woke themselves up around midnight. The late night period was known as “The Watch”. It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighbors.
According to some sleep researchers, a short of insomnia（失眠）at midnight is not a disorder. It is normal. Humans can experience another state of consciousness（清醒状态）around their sleeping, which happens in the brief period before we fall asleep or wake ourselves in the morning. This period can be a creative time for some people.
Playing with your sleep rhythms（节奏）can be dangerous, as worry may set in. Medical science doesn’t help much in this case. It offers us medicines for a full night’s continuous sleep, which sounds natural; however, according to Warren’s theory, it is really the opposite of what we need.
【小题1】The late night was called “The Watch” because it was a time for people ______.

A．to set time to catch animals

B．to remind others of the time

C．to guard against possible dangers

D．to wake up their family and neighbors

【小题2】We can infer from the last paragraph that people should ______.

A．sleep in the way animals do

B．follow their natural sleep rhythms

C．keep to the eight-hour sleeping way

D．ask doctors for help if they can’t sleep

【小题3】What is the writer’s purpose in writing the passage?

A．To throw new light on human sleep.

B．To encourage people to sleep less.

C．To give some suggestions on insomnia.

D．To find out people’s hibernating history.
