Women's minds work differently from men's.At least,that is what most men are convinced of. Psychologists view the subject either as a matter of frustration or a joke.Now the biologists have moved into this minefield,and some of them have found that there are real differences between the brains of men and women.But being different,they point out hurriedly,is not the same as being better or worse.
There is,however,a definite structural variation between the male and female brain.The difference is in a part of the brain that is used in the most complex intellectual processes一the link between the two halves of the brain.
The two halves are linked by a trunk line of between 200 and 300 million nerves,the corpus callosum.Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibres than it is in men.This is the first time that a structural difference has been found between the brains of women and men and it must have some significance.The question is"What?",and,if this difference exists,are there others?Research shows that present-day women think differently and behave differently from men.Are some of these differences biological and inborn,a result of evolution?We tend to think that is the influence of society that produces these differences.But could we be wrong?
Research showed that these two halves of the brain had different functions,and that the corpus callosum enabled them to work together. For most people,the left half is used for word-handling, analytical and logical activities;the right half works on pictures,patterns and forms.We need both halves working together. And the better the connections,the more harmoniously the two halves work.And,according to research findings,women have the better connections.
But it isn't all that easy to explain the actual differences between skills of men and women on this basis.In schools throughout the world girls tend to be better than boys at"language subjects" and boys better at maths and physics.If these differences correspond with the differences in the hemispheric trunk line,there is an unalterable distinction between the sexes.
We shan't know for a while,partly because we don't know of any precise relationship between abilities in school subjects and the functioning of the two halves of the brain,and we cannot understand how the two halves interact via the corpus callosum.But this striking difference must have some effect and,because the difference is in the parts of the brain involved in intellect,we should be looking for differences in intellectual processing.
Biologists are conducting research where psychologists have given up.
A:Right
B:Wrong

Travel Across Africa
For six hours we shot through the barren(荒芜的)landscape of the Karoo desert in
South Africa. Just rocks and sand and baking sun. Knowing our journey was ending,Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth,a beautiful leather notebook I'd bought in a market in Mozambique.
Southern Africa was full of stories and visions.We were almost drunk on sensations,the roaring(咆哮)of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.
And then the other things:dogs in the streets,whole families in Soweto living in one room,a kilometre from clean water.
As we drove towards the setting sun,a quietness fell over us. The road was empty一we hadn't seen another car for hours.And as I drove,something caught my eye,something moving close enough to touch them,to smell their hot breath. I didn't know how long they had been there next to us.
I shouted to Dan:“Look!”But he was in a deep sleep,his camera lying useless by his feet. They raced the car for a few seconds,then disappeared far behind us,a memory of he- roic forms in the red landscape.
When Daniel woke up an hour later I told him what had happened.
”Wild horses?”he said.”Why didn't you wake me up,Sophia?”
”I tried. But they were gone after a few seconds.”
”Are you sure you didn't dream it?”
”You were the one who was sleeping!”
”Typical”,he said.”The best photos are the ones we never take.”
We checked into a dusty hotel and slept the sleep of the dead.
Daniel and Sophia saw a lot of wonderful things.

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).
According to the passage,hearing loss is
A:only a minor health problem.
B:the world's most common health problem.
C:merely a teenage disease.
D:an incurable disease.
The high-speed trains can have a major impact on our lives.
A:effort
B:problem
C:concern
D:influence

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(唾液)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(切片)a big juicy lemon and sucking(吮吸)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(稀释的)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 professional singer.In the meantime,do not even talk in a low voice.
What about drinking alcohol to wet your throat?I advice 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 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 sinks 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 first paragraph mentions three ways of activating the saliva in the mouth.
A:Right
B:Wrong
C:Not mentioned
I don't quite follow what she is saying.
A: observe
B: understand
C: explain
D: describe
