Crystal Ear
One day a friend asked my wife Jill if I wanted a hearing aid."He certainly does,"
replied Jill.After hearing about a remarkable new product,Jill finally got up the nerve to
ask me if I'd ever thought about getting a hearing aid."No way,"I said."It would make me
look 20 years older.""No,no,"she replied."This is entirely different.It's Crystal Ear!"
Jill was right. Crystal Ear is different一not the old-styled body worn or over-the-ear aid,
but an advanced personal sound system so small that it's like contacts（隐形眼镜）for your
ears.And Crystal Ear is super-sensitive and powerlul,too.You will hear sounds your ears
have been missing for years.Crystal Ear will make speech louder,and the sound is pure
and natural.
I couldn't believe how tiny it is.It is smaller than the tip of my little finger and it's almost
invisible when worn. There are no wires,no behind-the-ear device. Put it in your ear and
its ready-to-wear mold（形状）fits comfortably. Since it's not too loud or too tight , you
may even forget that you're wearing it!Use it at work or at play.And if your hearing
problem is worse in certain situations,use Crystal Ear only when you need it.
Hearing loss,which occurs typically prior to teenage years,progresses throughout
one's lifetime.Although hearing loss is now the world's number one health problem,nearly
90 percent of people suffering hearing loss choose to leave the problem untreated.For
many millions,treating hearing loss in a conventional way can involve numerous office
visits,expensive testing and adjustments to fit your ear. Thanks to Crystal Ear,the
"sound solution"is now convenient.Almost 90 percent of people with mild hearing loss,
and millions more with just a little hearing drop-off（下降）,can be dramatically helped with
Crystal Ear. Moreover,its superior design is energy-efficient,so batteries can last
months.Crystal Ear is now available to help these people treat their hearing loss with a
small hearing amplifier（放大器）.
Which of the following is NOT true of Crystal Ear?
A:It is highly sensitive.
B:It is powerful.
C:It is invisible.
D:It is wireless.

Weaving with Light
In the Sierra Madre mountain range of west central Mexico,the native Huichol people live much the
way their ancestors did一without electricity,That’s because it's too expensive to string power lines to the
remote mountain areas where they live.To help support themselves,the Huichol create beautiful artwork.
They sell their art in cities hundreds of miles away from their villages.And without electricity一at home or
on the road,they can only work during daylight hours?When it gets dark,they must stop whatever they're
doing.
Now，a team of scientists,designers,and architects is using new technologies to provide the Huichol
with light after the sun sets.The scientists'technique involves weaving tiny electronic crystals into fabrics
that can be made into clothes,bags,or other items.
By collecting the sun’s energy during the day,these lightweight fabrics provide bright white light at
night一 Their inventors have named the fabrics" Portable（轻便的）Lights."Portable Lights have the potential
to transform the lives of people without electricity around the world.
At the core of Portable Lights technology are devices called high-brightness light-emitting diodes（高亮
度发光二极管）,or HB LEDs. These tiny lights appear in digital clocks, televisions, and streetlights.
LEDs are completely different from the light bulbs（灯泡）.Most of those glass bulbs belong to a type
called incandescent lights（白炽灯）.Inside, electricity heats a metal coil（线圈）to about 2. 200 degrees
Celsius.At that temperature,bulbs give off light we can see.Ninety percent of energy produced by mnean-
descent lights,however,is heat一and invisible.With all that wasted energy,bulbs burn out quickly. They
are also easily broken.
LEDs,on the other hand,are like tiny pieces of rock made up of molecules（分子）that are arranged in
a crystal structure.When an electric current passes through a LED,the crystal structure produces light. Un-
like incandescent bulbs,they can produce light of various colors.Within a LED,the type of molecules and
their particular arrangement determine what color is produced.
LEDs are different from light bulbs in that__________.
A:LEDg are made up of tiny pieces of rock
B:LEDs can send out light of different colors
C:LEDs belong to incandescent lights
D:LEDs look like crystals

1. Internet use appears to cause a decline in psychological well-being,（因特网的使用使人们的心理健康度下降）according to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on（进人电脑系统）less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet,but that using the Net actually appeared to cause the bad feelings.
2.Researchers are puzzling over the results,which were completely contrary to their expectations.They expected that the Net would prove socially healthier than television,since the Net allows users to choose their information and to communicate with others.
3.The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers hypothesized（假设）.Faceless, bodiless virtual（虚拟的）communication may be less psychologically satisfying than actual conversation,and the relationships formed through it may be shallower. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.
4."But it's important to remember this is not about the technology itself;it's about how it is used,"says psychologist Christine Riley of Intel,one of the study's sponsors（发起人）."It really points to the need for considering social factors in terms of how you design applications and services for technology."

Look After Your Voice
Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the
problem by activating the saliva in your mouth.First gently bite the edges of your tongue with your teeth.Or,
press your entire tongue to the bottom of your mouth and hold it there until the saliva flow. Or you can
imagine that you are slicing a big juicy lemon and sucking the juice.
Before you begin your talk,be kind to your voice.Avoid milk or creamy drinks which coat your throat.
Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.
If you sense that you are losing your voice,stop talking completely.Save your voice for your speech.You
may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you need to
see a doctor.perhaps you can get some advice from a orofessional singer. In the meantime,do not even talk in
a low voice.
What about drinking alcohol to wet your throat?I advise you not to touch alcohol before speaking.The
problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more
confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain
and your mouth do not work together properly.Save the alcohol until after you finish speaking.
Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a
lifetime.Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,"We learn
to skate in the summer and swim in the winter."Take this message to heart and give yourself time to develop
your new habits.If you are willing to change,you will soon be able. to say that you will never forget these
techniques because they became a part of your body.
The writer suggests that you go to see a doctor when you feel you are losing your voice.
A:Right
B:Wrong

More Rural Research is Needed
Agricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer,crop scientist,said demand was growing at 2 .5%per year but with modern tech-nologies and the development of new ones,the world should be able to stay ahead.
“The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition（营养不良）and poverty.” he said.
Research is needed to solve food production,land degradation（贫瘠化）and environmental problems. Secure local food supplies led to economic growth which in turn,slowed population growth .Dr. Fischer painted a picture of the world's ability to feed itself in the first 25 years, when the world's population is expected to rise from 5 .8 to 8 billion people.He said that things will probably hold or improve but there'll still be a lot of hungry people.The biggest concentration of poor and hungry people would be in sub-Saharan Africa and southern Asia in 2020,similar to the current pattern. if there is any change,a slight improvement will be seen in southern Asia, but not in sub-Saharan Africa. The major improvement will be in East Asia,South America and South-East Asia.
The developing world was investing about 0 .5%,or$8 billion a year,of its agricultural gross domestic product(GDP)on research and developed world was spending 2 .5%of its GDP. Dr. Fischer said more was needed from all countries.
He said crop research could produce technologies that spread across many countries,such as wheat production research having spin-offs（有用的副产品）for Mexico, China or India.
“Technologies still need to be refined for the local conditions but a lot of the strategic re- search can have global application,so that money can be used very efficiently.”Dr. Fischer said.
Yields of rice, wheat ad maize（玉米）have grown impressively in the past 30 years, espe- cially in developing countries.For example,maize production rose from 2 to 8 tones per hectare between 1950 and 1995.But technologies driving this growth such as high-yield varieties,fertiliz-ers,and irrigation,were becoming exhausted.“If you want to save the land for non-agricultural activities,for forests and wildlife,you're going to have to increase yield.”Dr. Fischer said.
What is the picture of Asia's food supplies in the first 25 years?
A: Food shortage will not be a problem.
B: There will be more hungry people in southern Asia.
C: Population growth will result in more hungry people.
D: There will be fewer hungry people in East Asia.

Early Ideas about the Universe
1 Early man got his ideas about the universe by looking at the stars as you do.He
observed carefully,and learned many things about the sun,the moon,and the stars.
2 Suppose you were asked to collect evidence about the sun as early man did.You might
go out morning after morning and see it come up in the east.Even on cloudy mornings,you
would observe that the darkness goes away and the world becomes light.You might not see
the sun but would be sure it is there,because you notice that the earth warms up.As you
continued,the sun climbs higher in the sky each day during part of the year. It stays in the
sky longer. The earth gets warmer. Things begin to grow. It is spring and then summer.
3 After a while the sun stays in the sky for shorter and shorter periods.Many plants begin
to die.Leaves fall.Winter comes.Year after year this is repeated and you cannot tell
exactly why it happens.But you realize that the sun seems to make the difference.
Primitive（原始的）man felt that since the sun was so powerful it must be a god. It may
seem silly to us now to worship（崇拜）a sun-god, but primitive man was right about the
importance of the sun to life on earth.
4 You have been told that the world is round.But suppose no one had ever taught you
that the world was like a huge ball.Would you have ever thought of it yourself?You cannot
see the curve（曲线）of the earth at once. You would have no idea of how big it was.
That's why early man believed that the earth was small and flat.Such ideas appeared from
the evidence they had.
5 If you watch the stars night after night,you will see them rise and set.As you look at
the sky,it is not difficult to imagine that you are in the center of a vast collection of twinkling
（闪烁）lights. Some early astronomers（天文学家）believed the sky was a crystal shell or
series of crystal shells,one inside the other. They believed this because that is what the
night sky looked like.For many centuries,men believed that the earth was the center of
the universe and that the sun,the moon,and the stars circled around it.

observed carefully,and learned many things about the sun,the moon,and the stars.
2 Suppose you were asked to collect evidence about the sun as early man did.You might
go out morning after morning and see it come up in the east.Even on cloudy mornings,you
would observe that the darkness goes away and the world becomes light.You might not see
the sun but would be sure it is there,because you notice that the earth warms up.As you
continued,the sun climbs higher in the sky each day during part of the year. It stays in the
sky longer. The earth gets warmer. Things begin to grow. It is spring and then summer.
3 After a while the sun stays in the sky for shorter and shorter periods.Many plants begin
to die.Leaves fall.Winter comes.Year after year this is repeated and you cannot tell
exactly why it happens.But you realize that the sun seems to make the difference.
Primitive（原始的）man felt that since the sun was so powerful it must be a god. It may
seem silly to us now to worship（崇拜）a sun-god, but primitive man was right about the
importance of the sun to life on earth.
4 You have been told that the world is round.But suppose no one had ever taught you
that the world was like a huge ball.Would you have ever thought of it yourself?You cannot
see the curve（曲线）of the earth at once. You would have no idea of how big it was.
That's why early man believed that the earth was small and flat.Such ideas appeared from
the evidence they had.
5 If you watch the stars night after night,you will see them rise and set.As you look at
the sky,it is not difficult to imagine that you are in the center of a vast collection of twinkling
（闪烁）lights. Some early astronomers（天文学家）believed the sky was a crystal shell or
series of crystal shells,one inside the other. They believed this because that is what the
night sky looked like.For many centuries,men believed that the earth was the center of
the universe and that the sun,the moon,and the stars circled around it.
