Many of us enjoy watching animals in the world. But do you know they can teach us?

Geese（雁）, for example, teach a very good lesson about ____. In the fall, Canada geese fly to the warm south to _____ Canada’s cold winter. They lift off in no order. Yet ____ they form a V shape, with one bird leading the group.

This V shape allows geese to ____ energy. When the front bird moves its wings up and down, the resulting force of the air lifts the next one. This continues down the line. The bird ____ has the hardest job. When it gets ____, it moves behind, and another bird moves into the lead. By sharing the role, the group can travel great distances. Geese flying in a V shape can fly 70 percent farther without ____ than birds flying alone.

During the long flying journey, geese communicate with one another. They honk（鸣叫）to ____ the birds up front to keep up the speed. They also cheer each other up ____ working toward a common goal.

What have we learned from the lovely geese's experience and skills?

____ together! Whether it is our personal lives or our jobs, we need other people. We need the spirit of teamwork!

In the eyes of many foreigners, Chinese are the best hosts（主人）and the worst guests in the world. They’re not really bad guests, but because the guest-host relationship in China is much different than in some western countries, it appears they are not nice guests. And western host sometimes look rude（粗鲁的）in the eyes of Chinese guests.

In China, guests are almost like gods. Whenever I enter a Chinese person’s home, there is always fruit on the table for me, and someone is quick to bring me a cup of tea or water. In the west, generally the guest is not a god. Acting according to the host’s way of doing things is usual behavior for a guest.

My wife’s mother, a very kind elderly Chinese lady, doesn’t smoke. When I see some of her guests smoking in her house, as a non-smoker, I feel unhappy. Usually I want to stop them directly, but I must realize that in China, to be a good host, she must not do that. In most North American homes, if you are a guest, and the hosts are not smokers, you should not smoke in their house. At the very least, you could ask. “Is it OK if I smoke?” But, don’t be surprised if they say “No, you can’t smoke.” In our culture, if you smoke in their home, you are a bad guest, but if they do not allow you to smoke in their house, they are not a rude host.

Guests in China also have special habits. Some western people may not adapt to these habits very soon. Thankfully my wife is Chinese,   so whenever we visit a Chinese family she tells me to buy them a gift. However, giving a gift to a host is not always necessary in my country. So, if you invite international guests to your house, don’t be too surprised if they don’t bring you a gift.

In China, you probably won’t need to change the guest-host relationship very much because you will probably only be the host, and Chinese are naturally very good hosts. If western hosts invite you to their house, try not to be too surprised if their style of treating you is not what you have expected.

Where does your food come from? How is it made? These days, many people worry about food safety. But food safety is not a new worry. In 1906, Upton Sinclair wrote the Jungle. The book is the story of a poor family in Chicago. It is also about the dangerous ways that food was prepared. People were so worried that the U. S. started testing food.

These days, most food in the world is safe. Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But it’s more important to make sure the rules are followed. A good food safety system（系统）keeps people safe. It also helps them eat healthy food. Labels（标签）on food give people important information. Then they can make good choices about their food.

Although food safety systems usually work, there can be problems. Sometimes mistakes are made. For example, a truck might carry eggs and then ice cream. The ice cream could make people sick when the truck isn’t cleaned before carrying it. Other problems are not mistakes. Sometimes companies break rules to make more money. When this happens, people don’t know if D their food is safe.

As we all know, food is closely related to our daily life. We should take action to make food safer.

I organized a picnic last Sunday. I got up e
35． and called some of my closest friends. First, we decided on a good p
36． to go, and then we talked about what food to bring. Everyone cooked the dishes that could be carried
37． (easy). Everything was put into a backpack and we
38． (take) it across fields. When we finally got there, we sat down eating, and enjoyed a nice day together. And I was quite sure that food tasted much
39． (good) on a picnic than anywhere else!

   Let me tell you about a young boy who made a model car all on his own. The boy is me, six years ago when I was just 11. The car was small and simple, but in my imagination it was a high-speed racing car, speeding along the race road.

It was during the school summer holidays and workmen were building a new driveway and garage(车库) beside our house. It meant to add something new to our home. When I watched the workman, I came up with an idea---I would build a car to drive into the garage in celebration of it. I told my mother and began with my plans. But I couldn't find the right things for making the car, so I gave up and sadly spent several days doing nothing. My mother noticed that I had stopped working and asked me why. I explained and she suggested that maybe I should change my plan to fit the things I had, rather than give up.

And that's just what I did. I found small pieces of wood in my father's workshop and made my car from anything that was lying around the house. When I found a small engine(发动机) from one of my old model planes, I added that. The power came from a battery I found in a box.

By the time the garage was finished, so was my car. I called my family together outside the house, started the engine and put the car on the driveway. It was fast, and I had to run to the garage to prevent it from hitting the new door. My family began to cheer and I smiled proudly. Thanks to my mother I learned the value of continuing to do things, especially something difficult. Soon I was making plans for my next project: a robot!
