It has a long neck, long legs and a walk like a camel. Its eyes are very large and sharp. Like the camel, the
ostrich can go for a long time without water. It lives in sandy desert, too.
Its wings are too short for flying, but they do help the ostrich to run fast. The wind gets under the wings
and lifts the bird off the ground. In this way, it can take very long steps. An ostrich can run faster than a
horse.
Ostriches are big and strong, but sometimes they do not seem very smart.
When they are afraid, they run around in circles.
Ostrich eggs are large. The shells are very strong. They are so strong that they can be used for cups and
bowls.

there will be less pollution in the air. There will also be more space for parking cars in cities, and the streets will
be less crowded. Three such cars can fit in the space now needed for one car of the usual size.
The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go
only 65 kilometers an hour.
The cars of the future will be fine for getting around a city, but they will not be useful for long trips. Little
cars will go 450 kilometers before needing to stop for more gasoline (汽油).
If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some
roads will be used for the big, fast cars and other roads will be needed for the slower small ones.

A bat has four legs. A bird has only two. Bats have teeth and birds have no. Bats have large ears but bird"s
ears only holes in the head.

better ears than men have. They can hear things which people can"t. They can feel where a thing is.

Each year, from top to bottom, a tree grows a new layer (层) of wood around itself. If you cut across a
tree trunk or branches, you would see that these layers of wood look like rings. By counting tree rings, you
can tell how old the tree is. If you count ten rings, for example, the tree is ten years old.
Looking at the picture shown above, you can see that each tree ring has a dark part and a light part. The
light part wood grows in the spring, the dark part wood in winter. Look also, that some rings in the picture
are wide and others are narrow (窄). Trees grow aide rings during the years when they get a lot of water and
sun-light. By examining tree rings, you can tell what the weather may was like many years ago.
Giant sequoia (红杉) trees, such as the one in the photo above, grow in north-western California. Some of
these sequoias have more than 3000 tree rings. Can you guess how old such a tree would be?

During the day we work and play; at night we sleep. Our bodies rest while we sleep. In the morning we
are ready to work and play again. While we are asleep our bodies grow most. Children who are tired usually
need more sleep. We can get our lessons better and we feel better too, when we have had plenty of rest.
Boys and girls who are eight or nine years old need ten hours of sleep every night. Our bodies need plenty
of air when we sleep. If we do not get enough fresh (新鲜的) air we"ll feel tired when we wake up. While
in bed we must not cover our heads. If we do, our lungs (肺) will not get enough fresh air. If we open our
windows at night we can have plenty of fresh air. Cool air is better than warm air. Boys and girls who want
to grow and be strong must get plenty of sleep.
