A smart diet, a healthy life
No matter how old your kids are, you can take steps to improve a healthy diet and to encourage good eating habits.
Tip One: Family Meals
Family meals are nice for both parents and kids. Children like to guess what they are going to have and parents get the chance to introduce new foods to children. Parents can also use the mealtime as a chance to talk with their kids about their life.
Tip Two: Healthy Snacks(零食)
Kids, especially younger ones, will eat mostly what can get at home. That’s why it’s important to have enough healthy snacks, such as fruits, vegetables, nuts, yogurt and whole-grain biscuits.
Tip Three: Being a Good Example
The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the
lead of the adults they see every day. By eating fruits and vegetables and avoiding fast food and sweet drinks, you are sending the right message.
Tip Four: No Shouts about Food
Parents might find themselves shouting at children to get them to have healthy foods in front of them. This in fact can make children dislike what they are asked to eat. You need to work a bit on different cooking methods(方式，方法).
Tip Five: Get Kids Included(参与)
Most kids will enjoy making the decision about food. Talk to them about making choices and planning a healthy meal. It can help them to make good decisions on their own about the foods they want to eat.

Geography is the study of Earth and its climates. Scientists use it to study global warming and track the weather. Governments use it to learn where people live and work and to plan what to do with the land. It is now easier than ever to use geography because of a science called space technology.

The United States launched its first satellite in 1958. Some space missions that followed were geographical studies. In fact, earth science is a big part of the work of the National Aeronautics and Space Administration (NASA).

Astronauts looked out of the space shuttle. They decided to take photographs of Earth from their vantage point. Over the years, picture quality improved. Shuttle photography now shows land features, such as rivers. It can even show the streets of large cities. Photos of the same places at different times show how the land is changing.

NASA does not use just photographs, though. In 1958 it launched TIROS (the Television Infrared Observation Satellite). This first use of a satellite to study Earth was effective in giving weather forecasts. It led to the creation of new space tools to use in geography.

The Landsat Program began in 1972. This satellite sent detailed views of Earth from space. The pictures were so precise that scientists could count the number and kinds of crops in a field. Landsat showed where Earth’s surface had faults along which earthquakes might happen. This information helped in the planning of new cities and factories. Landsat also made discoveries. In Antarctica it located ranges of unknown mountains. It pinpointed small lakes in Virginia that were no ton maps. Landsat, now more advanced, still flies today.

Another space tool is Earth Observing-1 (EO-1). This spacecraft flies right behind Landsat. It takes pictures of the same sites. The two sets of pictures, viewed together, show how cities grow and how other places, such as rain forests, become smaller over time. This helps scientists learn how people affect geography.

One of the newest space tools is the Geographical Information Systems (GIS). GIS is computer software that helps scientists to study Earth. GIS is different from earlier space tools. Businesses, schools, and even average people — not just the government —can use it to show them how changes in the planet might affect them.

1.Why do governments study geography according to the passage?

A. To improve the environment.

B. To make the land use plan.

C. To make new discoveries.

A. The U.S. satellite program began in 1972.

B. Landsat was able to take pictures of other planets.

3.EO-1 takes photographs of the same places as Landsat because __________.

A. the two groups of pictures can show the changes of Earth

B. EO-1 is practicing for future photography missions

C. Landsat is out of date and new pictures are needed

D. Landsat can’t send detailed views of Earth from space

4.From the passage, we can infer that ___________.

A. GIS is the newest computer to study Earth

B. NASA only depends on photos to study Earth

C. satellite pictures can give more detailed information
