【小题10】The sun gives us not only light but also________(hot)
The sun is a huge, hot, bright star. It is important because without it there would be no life on Earth. The
sun gives us light and heat.
All living things need light and heat from the sun to live. Plants need light and heat to grow. They use the
light from the sun to make food. We cannot make our own food, but plants can. All the food we eat comes
from plants in a food chain (链) which starts with the sun. For example,
Animals need sunlight, too. Just like us, their food comes from a food chain which begins with the sun
and the plants.
sun→ leaf→ caterpillar (毛虫)→bird
sun→ seaweed (海藻)→small fish→ whale (鲸)
Sunlight means we can see during the day. If there was no sun, it would be dark all the time. Even when
the sky is cloudy, the sunlight is very strong and it shines through the clouds.
B. Hot.
C. Bright.
D. All above.
B. Heat and eggs.
C. Corn and light.
D. Wheat and bread.
B. Because the sun can't give us light all day long.
C. Because the sunlight can shine through the clouds.
D. Because we can't see at night.
B. a food chain; sun
C. food; sun
D. plants; star
B. It can make rivers too dry.
C. Without it there would be no life on Earth.
D. Hot sun on dry land can cause fires.
The moon moves around the earth. It makes one trip in about four weeks. The moon looks flat to us. But it is a round ball, like the earth.
People once thought the moon had fire on it. They thought the fire made it bright. Now we know the moon is like a mirror. It gets its light from the sun.
Our sunlight comes from the sun, too. What is the sun? The sun is a star. The stars we can see have their own light. There are many big stars we cannot see. Their light had burned out. Others are still bright, but they are so far away that we cannot see them. The sun looks bigger and much brighter than other stars because it is the nearest of all stars. The sun and the other stars we see are very hot, but the air around us saves us from the heat of the sun.
The sun gives us light and warmth. It makes plants grow and turns leaves green. It makes life possible on our earth. It is a life giving star.
