     With an obese (very fat) or overweight population of 66% percent of adults, teaching your kids healthy eating habits is one of the most important things you can do for them as a parent.
      Most parents and children claim that breakfast is part of their everyday routines. But for many more
than you might think, it's not. Children who eat breakfast have higher math grades, have improved reading scores and basically perform better in school. They also tend to have healthier bodies in general, with
better-controlled weight levels.
     When you take them to the grocery store with you, it's doubtless that your children will request the
most sugar-filled, fat-injected products on the shelf. But these are not the ones to have in your home－you should avoid buying them at all. Be sure your kids have healthy snacks.
      Yes, kids like white bread. But any kid can get used to the taste of whole grains. It just takes a little
practice. Look for white bread, and add other whole grains into their diet. Start toasting their sandwiches. When it's toasted, it'll be that much harder for them to tell the difference in taste.
      It's simple, it's true, and it's something you already know: kids who get plenty of exercise are healthier kids. Set limits on the amount of time your child may spend in front of the television or computer screen.
Sign them up for plenty of sports and outdoor activities. And best of all, get involved in sports and exercise with them.
     One of the best things you can do to establish healthy eating habits in your kids is to have them yourself. You can tell your kids every day to eat healthy foods, but if you don't do the same thing yourself, the
lesson will never stick.

     Tomatoes are the world's most popular fruit rich in nutrition like Vitamin A, C, fibre and lycopene
(番茄紅素). Researchers have found that consuming lycopene helps in preventing cancer. Tomato
also helps in keeping the skin healthy and young by protecting from harmful rays. Since lycopene is
present in the cellular wall of tomato, it is better to consume cooked tomato to have higher concentration
of lycopene. So tomatoes are a wonderful fruit.
     Then how to grow tomatoes? First, there should be regular and even watering in the fields where
tomatoes grow. You can also add fertilizer to have better results. Plant the tomato plants with enough
space(for example 2 to 3 inch space)between each other to lessen spreading of disease and pests and
help the fruits get enough sunlight. Provide support like pole when the plants grow up to prevent from
disease and to increase the crop product.
     In order to make your tomatoes grow well, you should take some useful tips. For example, choose
variety based on the season and soil type that you are growing. Planting site should have enough sunlight
to have more fruits. Prune(修剪)the tomato plants if necessary to maintain a manageable size. Check
tomato plants regularly for any kind of pests and diseases.
    To people's regret, tomatoes possibly suffer from some diseases during their growth. So you must try
your best to prevent them. Soil should be free from debris(殘骸)of earlier plant remains and should be
treated first before tomato plantation like solarizing(曬) to prevent from pests. It is always better to
choose resistant plant varieties and follow crop rotation(輪作)as far as possible.

     No matter what he is doing, every human being gives body heat. The usual problem is how to dispose
of it. But the designers of the Johnstown campus of the university of Pittsburg set themselves the opposite
problem-how to collect body heat. They have designed a collection system which uses not only body heat
but also the heat given off by such objects as light bulbs and refrigerators as well. The system works so
well that no conventional fuel is needed to make the campus's six buildings comfortable.
     Some parts of most modern buildings-theatres and offices as well as classrooms-are more than heated
by people and lights and sometimes must be air-conditioned even in the winter. The technique of saving
and redistributing it is called "heat recovery". A few modern buildings recover heat, but the university's
system is the first to recover heat from some buildings and reuse it in others.
     Along the way, Pitt has learned a great deal about some of its heat producers. The harder a student
studies, the more heat his body gives off. Male students emit more heat than female students, and the larger
a student, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown
campus would be a hard-working, overweight male genius.

1. The underlined words "dispose of" in the first paragraph mean _____.
A. reuse
B. collect
C. get rid of
D. place in suitable positions
2. According to the passage,the following statements are true EXCEPT _____.
A. fat,male and hard-working students give off more heat
B. six buildings are heated by the heat system on the Johnstown campus
C. the heat is supplied by human bodies, other heat-omitting objects
D. the heat from human bodies, other heat-omitting objects is only used in cold winter
3. From the passage, we can infer that _____ would produce the LEAST heat.
A. a large female who does not study hard
B. a thin male who studies hard
C. a thin female who does not study hard
D. a large male who studies hard
4. The underlined sentence is _____.
A. indifferent
B. objective
C. serious
D. humorous

     No one knows yet the accurate number of lives which have been lost in this terrible fire. But reports
suggest that it is more than one hundred.
     A wall of flames fifty feet high and at least one hundred and fifty miles wide is now racing towards
the forests and rich farmlands of southern Victoria. Towns less than one hundred miles from Melbourne
will be in danger unless the wind changes. People are rushing excitedly into the streets. The police have
warned them not to see the fire but many people are doing so.
     The cause of the fire is unknown. No rain has fallen in this part of Australia for three months, and the
hot, north-west wind from the great central desert is blowing at more than thirty miles an hour.
     The firefighters are travelling to the fire by road, rail and air. But it is not easy to get there. Flames and
fallen trees have cut off or blocked roads and railway lines. The thick smoke often prevents them from
finding the air strips (飛機跑道).
     It is said that the fire has brought the greater danger to the country since the Second World War.

     No air means death. Although we can't see it, there is air around us. So air is everything and it gives life
to every living thing. Bad air makes people ill. We must have fresh air to keep us in good health.
     In the city there are a great many people and there are too many cars running on the roads. The gas which
the cars spread out is full of poison. Every day we breathe it in again and again. This makes us feel sick.
     Besides so many cars, there are many factories too. From the chimneys of these factories, we get the
smoke usually in black and grey colour. This kind of smoke, when it mixes the air, is dangerous to our health.
It is because smoke contains many poisonous solids and gases. So in order to keep us healthy we have to go
out to the countryside to breathe more fresh air. Or we can go up hills to get more fresh air.
