Sometimes,  people are not clear about what kind of food is healthy and what kind of food may do
 harm to our health. The USDA has prepared a food guide to help people learn about which kind of food 
is the  healthiest to eat.  The food guide describes six main food groups: meat  (like fish and chicken), 
dairy (like milk and cheese), grains (like bread and rice), fruit, and vegetables. The last group is fats and  
sweets.  The USDA also suggests how much of each food group is healthy   to eat daily. Though this 
guide was prepared by the US government, it  is very useful for people all over the world.       
     (1) As a result of years of study, we know that too much animal  fat is bad for our health.  For
 example,  Americans eat a lot of meat and  only a small amount (量) of grains, fruit and vegetables. 
 Because of  the way they eat, they have a high rate (率) of cancer and heart disease.  In Japan,  
people eat large amounts of grains and very little meat.  The Japanese also have a very low rate of 
cancer and heart disease.  The  Japanese live longer than anyone else in the world.  However,  when 
Japanese people move to the US, the rate of heart disease and cancer goes  up as their eating habit 
changes. And as hamburgers, ice creams and  other high-fat foods become popular in Japan, the rate
 of heart disease  and cancer is going up there as well.   (2)  People are also eating more  meat and 
dairy food in other countries. In those countries the disease  rate is going up with the change of people's 
eating habit.  Doctors everywhere suggest people eat more grains, fruit and vegetables and less meat  
and dairy food.      
     (3) Eating healthily is important for children as well as their parents. When parents have poor eating 
habits, their children usually do, too. After all, children eat the same way as their parents. When parents 
eat healthy food,  the children will learn to enjoy it,  too.  Then they will develop good eating habits.  
Doctors suggest parents give their children healthier food such as fruit, vegetables and juice.        
     Everyone wants to live a long,  healthy life.  We know that the food we eat affects (影響) us in 
different ways.  For example, doctors believe that fruit and vegetables can really protect people from 
many different diseases.  On the other hand, animal fat can cause (引起) diseases. We can change our 
eating habits now and enjoy many years of healthy living.

     There has been a new trend in food recently-people are becoming not interested in fast food and
beginning taking an interest in eating "slow food".
    For many years, the pace of life has been increasing for most people. Buying, preparing and cleaning
up after a meal was becoming a big trouble for those busy people. Luckily , there were smart business
people who took the opportunity to provide "instant" solutions to the problem. They opened fast food
restaurants. Almost overnight, you could go to the fast food restaurant, order your food and within 2
minutes it will be handed over to your hands.
    The problem is health. Fast food has much oil, salt and more calories and far fewer vitamins than
food freshly cooked at home. And so , since people have always wanted to live longer and healthier, a
small but growing population is choosing not only fresh food, but also organic food (有機(jī)食品) —food
that hasn't been grown with chemical fertilizers (化學(xué)肥料).
     Another reason for changes in eating habits is the society. Over the centuries,meal times have been
used to visit, laugh and learn. That doesn't fit with today's busy life and many people are looking for ways
to restore (恢復(fù)) that. Goodbye McDonald's.    
     Finally, there's something special about planning your meal, buying just the right ingredient (配料)
and seeing something on your table that looks just like the picture inyour recipe book (食譜書). So if
you're too busy, maybe it's time for you to slow down and enjoy ameal with a friend.

     Our world has been for many year and throughout all those years we have used the sun for energy
needs. So why not use the energy to our homes or our cars?Many scientists have changed forms of
energy called "Green Energy". Green power is the solution to creating a cleaner,sustainable energy
system. Renewable (可重復(fù)的)energy—from the sun,wind ,plants and moving water—is a natural way
to meet our energy needs and protect the environment.
    Solar (太陽(yáng)的) energy is a very useful resource today. 80% of the energy we use comes from fossil
fuels (化石燃料) and about 1 % comes from solar energy. Fossil fuels are nonrenewable,that means
that they are used up faster than they could be replaced. Also fossil fuels are limited and cause pollution.
They are the primary cause for air pollution that causes acid rain (酸雨) and global warming. The good
thing about solar energy is that it is renewable because it is always replaced. Also solar energy does not
pollute the environment.
     The energy problem is an important problem in the United States. Solar energy can help solve this
problem. But the cost is far too great.

1. The underlined word "natural"  means _______ in Chinese.

A. 有用的
B. 有趣的

A. Solar energy is a very useful energy.
B. Solar energy is renewable and replaced.
C. Solar energy can pollute the environment.
D. Solar energy can help solve energy problem in America.

5. Which is the best title for the passage?

A. Solar Energy
B. Fossil Fuels
C. Our World's Energy

      What will happen if you don't eat your breakfast? A short time ago,a test was given in the United
States.People of different ages,from 12 to 83,were asked to have a test.During the test,these people
were given all kinds of breakfast and sometimes they got no breakfast at all.Scientists wanted to see
how well their bodies worked when they had had different kinds of breakfasts.
     The results show that if a person eats a right breakfast,he or she will work better than if he or
she has no breakfast.If a student has fruit,eggs,bread and milk before going to school,he will learn
more quickly and listen more carefully in class.

people become so hungry at noon that they eat too much for lunch.So they will gain weight instead
of losing weight.

　　The Great Lakes between the US and Canada are the largest bodies of fresh
water in the world. For a long time, people lived happily beside the Lakes until
the countries began to build factories along the shores. Pollution was killing the
Lakes, pretty soon, the Lakes' ecosystem (生態(tài)系統(tǒng))was not right any more.
Scientists knew something had to be done.So did the government(政府). They
learnt it was important to keep the ecosystem of the Lakes healthy and strong. If
the Lakes dried up, the whole world would feel it.
Many areas would become deserts and many animals would lose their homes and
maybe die out. As a result, they set up a lab called the Great Lakes
Environmental Research Laboratory to solve(解決)the problem.
