What should we do to keep healthy? One important rule is to exercise 1 . The Fang family try to exercise
every day. Mr Fang 2 exercise in the morning because he must get to work at exactly seven o"clock. But he
runs every evening. He walks a lot, 3 . He walks to school every day, and after school he 4 different
sports with his friends. Mr Fang goes to a yoga (瑜加功) class 5 .
But it wasn"t 6 this way. Last year Mr and Mrs Fang used to (过去常常) 7 everywhere in their car,
even to the drugstore (药店) two blocks (街区) away. They thought they had to use the car all the time. They
wouldn"t walk.
The Fangs all 8 better now. They believe they shouldn"t be lazy. We 9 exercise every day, but we
should try our 10 to exercise as often as possible.
On December 7-18, 2009, there was a meeting about climate change in Copenhagen (哥本哈根),
Denmark (丹麦). 1 A warmer earth does a lot of harm to our lives and the environment. Spring is
arriving earlier. There are more and more droughts (干旱). Because of these, many kinds of animals
and plants may disappear. 2 Many plants will stop growing. Lots of people and animals will not
have enough food.
People are cutting more and more trees. 3 If we want to have a better future, what should we
do then? Walk to school. 4 If your school is far away from your house, take a bus. Use air
conditioning (空调) as little as you can. You can wear more clothes in winter and use a fan in summer.
5 Use energy-saving lights.
