When we have small cuts in the skin (皮肤), something strange may happen.The cuts are able to heal
(痊愈) themselves in a couple of days. How does this happen? Read on, and you will find out the secret.
     Every living thing on the earth is made up of cells (细胞). Cells grow and make new cells. Most cells
are very tiny and we can't see them with our eyes. Different cells have different uses. Our skin cells are
special ones.The cells on the surface (表面) of our skin are old dead cells. New skin cells are right under
the surface. These are the living skin cells. They do work for our bodies. They help protect our bodies
and heal cuts. 
     Our bodies make skin cells all the time. As the old cells fall off, new cells grow in the same place. Each
person makes about 18 kg of skin cells during his or her life.Surface skin cells fit together closely with no
gaps between them. When you cut or bum yourself, you can harm your skin cells. A small cut will not do
much harm. Your skin will quickly heal itself by making new skin cells. How do skin cells work? First, the
cells near the cut get bigger and move into the gap. Next, these bigger cells meet in the middle. They form
a new layer (层) of skin cells. Finally, new cells will grow until the gap disappears completely. In this way,
your skin can grow and get well itself.
    How amazing the tiny cells are! Next time you have a cut, don't worry about it.Maybe in a few days, you will be surprised to find it healed.

    Elephants are interesting animals with large ears, a long trunk, and short legs. They use their legs to stand and
walk. Unlike (不像) lions and tigers, an elephant cannot use its legs to jump or run fast. But elephants do have
something that most animals do not have — a trunk!
    It is difficult for an elephant to bend (弯曲) down to reach food on the ground because of its short, fat legs.
That is why an elephant has a trunk. It uses its trunk to reach food it needs. Without its trunk, an elephant would
be helpless.
    An elephant uses its trunk as a monkey might use its arms and hands. The elephant can scratch (抓) an itch
(痒), pick up a small peanut (坚果) or a piece of popcorn (爆米花), and touch objects with its trunk. An
elephant's trunk can even wrap (裹) around a tree and pull it out of the ground. An elephant's trunk also helps it
drink water. An elephant can drink as much as 50 gallons (加仑) of water into its trunk. Then the elephant
squirts (喷出) the water into its mouth and down its throat (喉咙). An elephant's trunk is very useful!

    Scientists (科学家) think that many animals cannot see colours. The world is black and white to them.
Scientists want to find out if (是否) dogs can see colours. When the scientists give the dogs food, they show
them a certain colour every time. The dogs get ready to eat when they see this colour. The scientists then show
the dogs another colour. Again the dogs get ready to eat. The colours are all the same to them.
    Colours are not all the same to monkeys. For example, if we put food in a red box, and do this every day, a
monkey will always go to the red box to get food. If we put food in a blue box, the monkey won't go to it.

     Maybe that doesn't sound interesting. But when we've joined the Internet, there are lots and lots of things
we can do. We can have a lot of interest on the World Wide Web(www). We can use the Internet instead of a
library to find all kinds of information for our homework. We can find information about our favourite sports or
