As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.
Experts on dyslexia say that the problem is not a disease.They say that persons with dyslexia use information in a different way.One of the world's great thinkers and scientists,Albert Einstein was dyslexic.Einstein said that he never thought in words the way that most people do.He said that he thought in pictures instead.The American inventor Thomas Edison was also dyslexic.Dyslexia first was recognized in Europe and the United States more than 80 years ago.Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled.The doctors found that the brains of persons with dyslexia are different.In most people,the left side of the brain一 the part that controls language is larger than the right side.In persons with dyslexia,the right side of the brain is bigger. Doctors are not sure what causes this difference.However,research has shown that dyslexia is more common in males than in females,and it is found more often in persons who are left handed.No one knows the cause of dyslexia,but some scientists believe that it may result from chemical changes in a baby's body long before it is born.They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help.After they have solved their problems with language,they often show themselves to be especially intelligent or creative.
Many great thinkers and scientists in the world are dyslexic.

  Cooking Oil Fumes Cause Tumor
  The leading cause of lung cancer among women in the city was cooking oil fumes while men are more likely to develop the disease from smoking,said medical experts after a five-year research study.
  Doctors announced the results yesterday with analysis on some new tendencies in lung cancer. They said patients are younger,especially women.
  According to the Shanghai Tumor research Institute,more local residents die of lung cancer in the city than anything else.Following breast cancer,it has the second-highest incidence rate.
  “An unhealthy lifestyle is a very important reason for lung cancer,”said Dr He Yumin from Shanghai Minshen Traditional Chinese Medicine Tumor Diagnosis and Treatment Center.
  He followed 2,276 lung cancer patients for five years.Among them,1,483 were male.
  Smoking causes 70 percent of cases among men while only 18 percent of female patients developed cancer from smoking or inhaling second-hand smoke,according to the report.
  However,more than 60 percent of women with the disease had long term,close contact with strong oil fumes from cooking and complained about irritated eyes and throat.
  About 32 percent of women fried foods in boiling oil in unventilated kitchens and about 25 percent of women's bedrooms were adjacent to the kitchen.
  However,local women were surprised to learn cooking oil fumes could lead to cancer.
  Some claimed they may change food preparation methods.
  “Unless my family and I don't eat at home every day,I must stay in the kitchen to cook,”said Xu Li,a 45-year-old local woman. “I know the fumes are bad for the skin,but it is the first time I heard that it can result in lung cancer. I have already started frying less.”
  Doctors said women's lung cancer had few links to personal health and physical condition,but was closely related to family cancer history,unhealthy dietary habits and weak immune systems.
  Other experts agreed with him.
  “Smoking is by far the biggest cause of lung cancer for men,”said Dr Tan Binyong, honorary president of the Respiratory Disease Institute at Fudan University's Medical College.“It's true that second-hand smoke and cooking fumes are the main causes among women.”
  His research also warned people not to stand near of stalls selling fried foods due to the poor quality of oils used.
  The chance of catching lung cancer is three times higher if exposed to the fume for a long time,6 experts said.
  What a new tendency in lung cancer is concluded by the researchers?
  A: Men are more likely to develop lung cancer than women.
  B: Women are more likely to develop lung cancer than men.
  C: Patients with lung cancer become older,especially males.
  D: Patients with lung cancer become younger,especially females.

  1. Icebergs are among nature's most spectacular（壮观的）creations , and yet most people have never seen one.A vague air of mystery envelops them.They come into being somewhere in faraway, frigid waters,amid thunderous noise and splashing turbulence,which in most case no one hears or sees. They exist only a short time and then slowly waste away（消融）just as unnoticed.
  2. Objects of sheerest（最纯粹的）beauty they have been called. Appearing in an endless vaniety of shapes,they may be dazzlingly white,or they may be glassy blue,green or purple,tinted faintly on in darker hues.They are graceful, stately,inspiring in calm,sunlight seas.
  3.But they are also called frightening and dangerous,and that they are一in the night,in the fog,and in storms.Even in clear weather one is wise to stay a safe distance away from them.Most of their bulk is hidden below the water,so their underwater parts may extend out far beyond the visible top.Also,they may roll over unexpectedly,churning the waters around them.
  4.Icebergs are parts of glaciers that break off,drift into the water,float about awhile,and finally melt.Icebergs afloat today are made of snowflakes that have fallen over long ages of time.They embody snows that drifted down hundreds,or many thousands,or in some cases maybe a million years ago.The snows fell in polar region and on cold mountains,where they melted only a little or not at all,and so collected to great depths over the years and centuries.As each year's snow accumulation lay on the surface,evaporation and melting caused the snowflakes slowly to lose their feathery points and become tiny grains of ice.When new snow fell on top of the old,it too turned to icy grains.So blankets of snow and ice grains mounted layer upon layer and were of such great thickness that the weight of the upper layers compressed the lower ones.With time and pressure from above, the many small ice grains joined and changed to larger crystals,and eventually the deeper crystals merged into a solid mass of ice.
  Paragraph 4___________
  A:Formation of iceberg
  B:Iceberg is beautiful
  C:Color of iceberg
  D:Iceberg is dangerous
  E:Iceberg is mysterious
  F:Classification of iceberg

  Tiny Invaders
  The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
  and to move from place to place.In fact,the human body does its work so well that most people don't think
  about it very much-until they get sick.
  The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
  They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
  are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
  live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
  creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
  good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
  How can you stop these tiny invaders from making you sick?Your skin is the first defense against
  germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
  body through small cuts in the skin or through the mouth,eyes,and nose.
  Once germs are inside your body , your immune（免疫的）system tries to protect you. It looks for and
  destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
  Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
  germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
  germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
  That way you will not get the same illness twice.
  You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune systerm
  strong. You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are
  medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.
  Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your
  antibodies attack it.
  Vaccines can make you sick.
  A:Right
  B:Wrong
  C:Not mentioned
