Raising chickens seems a difficult task for teenagers. Gracie Goodpasture, from Virginia, US, not only raises them, but also tries to breed (喂养) the “perfect chicken”. And she even won an award for her love of science.
Gracie started breeding chickens in her third grade at Steward School. At first, she worked on some farms for her school project. But later, the 14-year-old started to have some ideas of her own.
“Some have thicker eggshells (蛋壳), and they’re hearty (健壮的) throughout the winter,” said Grade.
Since then, the young science lover started to try to find the healthiest free-range (散养) chickens. And she ended up breeding a type that now bears her name.
The National Science Teachers Association (NSTA) gave the 2015 Angela Award to Gracie Goodpasture. Her interests don’t end with chickens and eggs. She is also into building robots and testing preservatives (防腐剂) in fast foods. In her words, she wants to go to Virginia Tech for poultry (家禽) sciences in the future.

The days are getting shorter and shorter, and temperatures are dropping. Winter is coming and it is easy for people to catch flu. Many people have started taking vitamin C pills as a precautionary(预防的)way. But a research has shown that vitamin C pills do not provide as much protection as they think. They are even not as good as other ways, like often washing your hands. Some German scientists have given people information and a test on the subject helping to stop incorrect ways.
Whether it is caused by cold or flu(流行性感冒), a runny nose and sore throat are signs of catching a cold. Many people overestimate(高估) the advantages of vitamin C and other pills. For years it was believed that taking vitamin C pills not only provided protection against colds but also against cancers, helping people to live longer. But the result of the research showed disagreement on these beliefs(看法). The result has now come out on the website wwww.informedhealthonline.org. “Some pills may not help people live longer. Some pills may even lead to earlier death,” says Professor Peter Sawicki. Scientists also say that the best way to get vitamins is through food instead of having vitamin pills. That is to say, we disagree with the way of taking vitamin C pills.
There are many simple but useful ways to lower the risk of catching a cold. These include often washing your hands with normal soap(肥皂) and water and not touching your face with your hands. People who have already had a cold can stop it from spreading by throwing away tissues(纸巾) at once after using them and not shaking hands with other people.

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.
| A．突起 | B．条纹 | C．缝隙 | D．代沟 |

| B．Different cells have different uses in our bodies. |
| C．The skin cells have little work to do in the body. |
| D．Every living thing on the earth is made up of skin cells |
The best title for this passage should be______.
| A．How Skin Cells Heal Cuts |
| B．The Importance of Skin |

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.
