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 small and we can't see them with our eyes. Different cells have different uses. Our skin cells are special ones. The cells on the outside of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells. They 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. Outside skin cells fit together closely with no gaps between them. When you cut yourself, you can harm your skin cells. A small cut will not be harmful. 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. In this way, your skin can grow and get well itself. How amazing the small 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.The underlined word “gaps” in the passage means “______” in Chinese.

Have you ever heard an echo of your voice?
An echo is a reflected(反射)sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called “echoes”.
We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard(纸板筒).
Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear.
A megaphone(喇叭筒)works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far.
We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them.What is called “echo”?
| A．Very loud voices. |
| B．Very loud voices that are made by man. |
| C．Very loud voices that are made by animals. |
| D．The sound that is made by man or animals comes back from some place. |
We can hear our echoes if we .
| A．shout in a small room |
| B．shout in a large house full of things |
| C．shout in narrow valleys(山谷) |
| D．shout in the open air |
Which is the right order of hearing our echo in a very large, empty hall?
a. We hear the reflected sound
b. The sound returns to us
c. The sound hits the walls
d. We make a sound
| A．c, b, a, d | B．c, a, b, d | C．d, c, b, a | D．d, b, c, a |
From the text we learn that __________ .
| A．reflected sound is useful only to blind people |
| B．people haven’t made use of reflected sound yet |
| C．bats use reflected sound to fly and get food |
| D．whales don’t use reflected sound as they live in the sea |
If you haven’t got a megaphone, ____ will help you to make your voice travel farther.
| A．a long piece of wood | B．a roll of cardboard |
| C．a thin thread | D．a long piece of silk |
There are many things we need to know, but we do not learn them at school. For example, if we want to use our money wisely, we need to shop carefully. We need to know how to compare(比较) the prices of the things in different shops. We also need to know how to make the best choice when we shop.
Knowing how to make such choices is a life skill, and we need to practice it in our daily life.
