7.The federal school lunch program for 30 million low-income children was created more than half a century ago to combat malnutrition(营养不良).A breakfast program was added during the 1960s,and both attempted to improve the nutritional value of food served at school.
More must be done to fight the childhood obesity(肥胖) epidemic,which has caused a frightening peak in weight-related disorders like diabetes,high-blood pressure and heart disease among young people.The place to start is schools,where junk food sold outside the federal meals program-through snack bars and vending machines-has pretty much canceled out the benefits of all those efforts.
Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years.Until new regulations are written,children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium(钠) snacks elsewhere in school.
Many states'school districts have taken positive steps,but others are likely to resist,especially districts that sell junk food to finance athletic program extracurricular activities,and even copier expenses.
Those districts should take note of a study released in 2009 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice,milk,and water were very little.Even if the switch costs money,so be it.The school should not be trading their students'health to buy office supplies.
Over the last five decades,the obesity rates for adolescents have tripled.Unless there is decisive action,weight and inactivity-related disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death.

32.According to this passage,Bare to blame for the childhood obesity.
   A.weight-related disorders               B.high calorie snacks

   A.Federal governments deserve high praise for their school lunch program.
   B.New regulations are badly in need of updating.
   C.Children should be forbidden to buy snacks in school.
   D.Federal rules encourage snacks outside the school program.
34.The passage is concerned mainly withC.
   A.Malnutrition in low-income children
   B.The federal school lunch program
   C.obesity at school
   D.the nutritional value of food served at school
35.The tone of this passage isA.
   A.negative          B.indifferent          C.optimistic         D.ironic.

20.Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem:It seemed impossible to get the thread to run around the needle without any problems.
Though he was tired,Howe slept badlyHe turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practised sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Brone also drew in her dreams in writing Jane Eyre.
To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious(无意识的),but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious par acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called"secret messages to us".

21.The problem Howe was trying to solve wasD.
A.what kind of thread to use
B.how to design a needle which would not break
C.where to put the needle
D.how to stop the thread from getting caught around the needle
22.Thomas Edison is spokenof becauseB.
A.he also tried to invent a sewing machine  
B.he got some of his ideas from dreams
C.he was one of Howe's best friends        
D.he also had difficulty in falling asleep
23.Dreams are sometimes called"secret messages to ourselves"becauseA.
A.strange images are used to communicate ideas
B.images which have no meaning are used
C.we can never understand the real meaning
D.only specially trained people can understand them.
