Take a look at the label(標(biāo)簽) on almost any bottle of milk and you may see the word PASTEURIZED. What does that mean? Let’s find out by meeting Louis Pasteur.

Louis Pasteur was born in 1822 in a little town in France. As he grew up, he loved to paint. He loved to look at the world around him. When he went to college in Paris, he showed interest in looking through a microscope. A microscope makes things look a lot bigger; it lets you see things you can’t see just with your eyes. Looking through a microscope, Pasteur found a living world in a drop of water. He saw and drew pictures of the small living things -- he called them “microbes” or “germs”-- that crowded in a drop of water.

One day a winemaker came into the lab, hoping that someone could help him with his problem. “Sometimes my wine tastes delicious, but sometimes terrible,” he said to Pasteur. “Can you help me find out why?”

Pasteur put some drops of the wine under the microscope. He noticed that the terrible wine had some unusual germs. If he killed these germs, maybe he could keep the wine from turning terrible. He tried with different ways to kill the germs. In the end he found heating (加熱) the wine seemed to work best. The winemaker tried it, and every bottle of wine tasted good.

Pasteur’s idea worked for other people, too. When farmers heated milk, it didn’t turn bad so quickly. When breweries heated beer, it tasted better. People called it “pasteurization” ---heating a liquid to kill bad germs. Aren’t you glad that the milk you drink has been pasteurized?

A couple of years ago, I went to Australia for a meeting with my friend, Chris. We decided to drive across country to Brisbane after the meeting ended. The drive was going to take four days and most of it was across the desert,    81   
The first day was a lot of fun as we were excited and laughing at each other's stupid jokes. By the third day of driving in the seemingly endless desert, we began to get bored. We had been quiet for a few hours when in the distance Chris found some kangaroos. We were both excited and decided to get a closer look.   82  We got closer and closer, and Chris was doing 110 kilometers per hour. We were very close to the kangaroos—too close—when we heard a loud BANG!
Chris stopped the car and we got out. Behind the car was a larger kangaroo lying completely still on the ground.    83  He took off his sunglasses and put them on the kangaroo and did the same with his jacket. Then, he put his arm around the kangaroo and told me to take a photo of them together.   84  While I was focusing the camera, I saw the kangaroo move. It suddenly woke up, looked at Chris, and jumped away into the distance before we could do anything.
I started laughing but Chris looked very serious.   85   I started laughing even harder. I stopped laughing, however, when he said that our car keys were also in the jacket!

A．Chris speeded up to catch up with the kangaroos. B．He said his wallet and passport were in the jacket. C．In order to get there in three days, we drove very fast. D．so we had to take food, water, and extra gas with us. E. Chris went over to the kangaroo and put his baseball cap on its head. F. I was still surprised, but I took out my camera.

Look into the mirror and what do you see? You see yourself. But when you move. you do everything backward(相反地)in the mirror! If you wave your left hand, your right hand waves in the mirror. If you wink your right eye, your left eye, your left eye winks(眨). Try to read a page in the mirror .The words will be backwards.

Mirrors have been used for thousands of years. The earliest were round pieces of shiny metal. Glass mirrors came late. The ancients thought that a mirror was magic. They did not understand how it worked. They thought they saw their spirits in a mirror and breaking a mirror brought bad luck.
Today mirrors have many uses .For example, they can make rooms look bigger and prettier. They also show us if our hair is combed(梳理) well and our faces are clean. On cars, buses and trucks, mirrors help drivers see traffic behind them. Mirrors are also used in telescopes(望遠(yuǎn)鏡)and searchlights(探照燈).

For as long as I can remember, Grandma’s plentiful tomato garden has been a sign of summer’s end. Each September, just as the decreased heat of the sun suggests cooler days, Grandma requests (ask for something) my help in her tomato garden. I’m sure that she cannot pick tomatoes without my youthful eyes and quick mind. She says we need to examine each tomato and agree on its readiness for picking. While Grandma’s request for my help in the tomato garden is always the same, her desire for my help seems to increase each year.
　　Grandma has eyes for finding even the tomatoes hidden by undergrowth and other tomatoes. I, however, just turn circles looking for the ones I think Grandma will like. I spot what looks like a ripe（成熟的）tomato, head in its direction, and then get sidetracked by another that appears to be equally ripe. I usually end up watching Grandma and trying to stay out of her way, which seems the only way my eyes and mind are useful.
　　There we are, lost in the tomato vines（藤）. Grandma’s eyes are always knowing, and they are no different in the vegetable garden. From afar she spots (notice) what looks like a ripe tomato. As she walks toward the garden, she evaluates the tomato for a second time, but from a different angle. I already know it will end up in the basket with the pile of others Grandma has carefully chosen. However, Grandma acts as if she needs a final look to be sure. She calls me to her side, kneels beside the vine while enjoying the warmth of the fading sunlight on her face, and grasps the tomato in her hand. She turns each round, red ball toward the sunlight before disconnecting it from the vine with a half-hearted smile.
　　She then looks at me. I nod my head and smile. Grandma assumes I smile in agreement with her tomato selection. I know I smile, instead, at her.
