I'm David．Not long after I started my college course(课程)，I began to look for some work experience．It was a busy course，but I had a free day each week．I wanted to do all I could to make myself employable(具备受雇条件的)．Like many students，I was worried about leaving college with no job to go to．And this encouraged me to go out and look for placements(实习职位)．

    I had several different placements．I decided I wouldn't let any opportunities(机会)go．I quickly realized that me way to impress possible employers

is to show them，that you are ready to work hard．Employers don't want someone who just does what they are asked and makes tea．What's more．I took every placement I was offered even if it didn't have to do with my course．

Among the things I did was to work at a radio station and at a newspaper．I think it's been more useful than just reading books．You do need to study，of course，but college doesn't teach you everything．I have much more confidence(信心)now．I'm ready to deal with anything．While I was working at the radio station，I met a lot of interesting people and they helped me a lot．Some of them may help me find work in the future．I certainly advise getting some work experience while you're in school．

    The Internet is becoming more and more popular. It brings us a lot of fun and convenience, 但它也引起一些新的问题。Children like the Internet. They would rather communicate with others online than talk with their parents.

    On the one hand, in my opinion, the Internet brings people closer. On the other hand, 如果我们花太多的时间在网络上， we will have less time with our families and friends in the real world.

    Parents are always staying with us. So why not talk to them face to face when we have problems. If so, I'm sure that we can get on well with our parents.

Have you ever imagined how people eat in space? It's not easy. In a word, it is different from that on Earth. The food that astronauts carry with them doesn't look like the food you eat.

Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed （去掉）from the food. In the space capsule （太空舱）, the astronaut puts the water back. He "shoots" hot or cold water into the food bag with a special gun （枪）. He eats the food through a small hole in the bag.

Other foods come in bite-size （一口大小的）. The astronaut puts a whole piece in his mouth each time. There can't be crumbs（食物碎屑）. Crumbs would float around the capsule and get in the way. Meat, cakes and cereal（麦片）often come in bite-size pieces.

Astronauts can't drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his month.

Do you think it difficult to eat in space? Astronauts must learn to eat this way.

A Fun Plant Experiment to Try at Home

Without water, plants would die. How does water get from roots of a plant to the other parts of the plant? The water travels through" small pipes" to all parts of the plant. And here is a scientific experiment to show it. 

What we need:

* a celery stalk(芹菜茎) with leaves

* a knife

* some red food colour from tomatoes

* a glass of water

How we do it:

1. Put a few drops of the red food colour in the glass of water. 

2. Cut the bottom(底部) of the celery stalk and place the celery in the water. 

3. Leave the celery stalk in the glass of water for a few hours. 

4. Take the celery stalk out of the water and cut it into pieces across the stem. 

What happens:

You can see red food colour in all cross parts from the bottom of the celery stalk right up to the leaves. 

Why it happens:

The water, with the red food colour, has run in the celery stalk through the small pipes in it. The experiment, therefore, shows that the small pipes in the plant allow water to reach all parts of it. The red food colour shows where the water has travelled in the celery stalk. 

 Shyness is a kind of fear. People who are shy always worry too much about what people think of them or embarrassing themselves in some way in front of others. How can we overcome shyness?

◆Have a good posture (姿势)

 The way a person holds himself/ herself says a lot about that person. People with sloped (倾斜的) shoulders don't think of themselves as important. To have a good posture, you should stand up straight, shoulders back, keep your head up, and always look at the eyes of others. By practicing a good posture, you will feel you have the ability to do things well. 

◆Increase your walking speed

 You can tell if a person is confident by the way he walks. People who walk in a slow way, and look at the ground while walking usually have no confidence in themselves. While people who have confidence in themselves walk faster. That is because they have important things to do, friends to meet, places to go, etc. So walk a little faster, head held up, and look straight ahead. 

◆Do some exercise

 Exercise increases your energy in the body. That will put you in a more positive (积极的) state of mind. By having exercise, you will feel sure of yourself. Think about it. It is better to do some exercise than just watching TV all day. 

◆Do things you enjoy

 This can be anything that you really enjoy doing, like traveling, going to the theater, listening to music, helping someone out with a problem, etc.
