Imagine the situation. You are driving in a village or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car doesn’t work. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is used for finding your position(位置) with the help of satellites (卫星). A GPS can’t start your car, but at least you will know where you are.

? GPS, which means Global Positioning System(全球定位系统), is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find a GPS in cars, planes, or boats. Some of them have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

? There are three parts to GPS. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites going around the Earth. The receiver communicates with at least four of the satellites and calculates its position. The third part of the system is a network of ground stations all over the world. They control (控制) the satellites and make sure they are working well.

? Some people think that in the future the GPS will be as common as the mobile. They are becoming better and cheaper. There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

One of sweetest memories as a child is of going down to the river and sitting comfortably on the bank. There I would enjoy the peace and quiet, watch the water rush downstream and listen to songs of birds. I would also watch the bamboo trees bend under the pressure from the wind and watch them return gracefully to their original state after the wind had died down.

When I think about the bamboo tree’s ability to bend and move back, the word “resilience” comes to my mind. When it is used for a person, this word means the ability to readily recover(恢复) from shock, sadness or any other suffering. Have you ever felt like you were going to snap? Have you ever felt like you were at your breaking point? Thankfully, you have survived to talk about it.

Life is a mixture(混合) of good times and bad times, happy moments and unhappy moments. The next time you are experiencing one of those bad times or unhappy moments that take you close to your breaking point, bend, but don’t break. Try your best not to let the situation get the best of you.

An amount of hope will take you through the unpleasant suffering. With hope for a better tomorrow or a better situation, things may not be as bad as they seem. The unpleasant suffering may be easier to deal with if the end result is worth having.

If things get tough and you are at your breaking point, show resilience. Like the bamboo trees, bend, but don’t break!

1.What does the word “snap” in the second paragraph most probably mean?

A. break                                B. change

C. win                                  D. Complain

2.What can help people get through sufferings according to the writer?

A. Holding peace and quiet in mind.          B. Waiting until sufferings disappear.

C. Experiencing more bad times.             D. Hoping for a better tomorrow.

3.What would be the best title of this passage?

A. Memories of Bamboo                    B. Be Like Bamboo

C. Enjoying Bamboo                       D. Characteristics of Bamboo

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!

Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.

"We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."

British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.

But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It's hard to get a clear result.

Will there be a better indicator than litmus paper? The three kids decided to try and find out!

How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.

The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best color change. They decided it was the litmus paper!

"It's our first scientific journey, Huang said, "But it makes me want to try harder."

C. Robert Boyle

It is said that another acre of the world’s forest will be destroyed forever. Why is this happening? There are two reasons — land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don’t know that in most places the trees won’t be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The  forest becomes a desert. Then more land will be needed, and more trees will be cut down.

When the forest is destroyed, it isn’t only the trees that are lost — the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger — fish,reptiles, birds, mammals, insects, and shellfish — as well as thousands of plants.

Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world’s population is now six billion. Of course, it’s very easy to blame the local people. We don’t cut down trees. They do. But the products are bought by people like you and me — wood houses, beds, tables, chairs, paper… Why are the forests being destroyed? Just look around. You are probably using it right now.

1.People cut down large areas of trees in order to _________.

    A. grow crops        B. keep animals    C. build houses   D. get land and wood

2. In most places, __________after trees are cut down.

A. new trees can grow better                  B. forests will become deserts      

C. most animals can live there                 D.people build new house there

3. According to the passage, we should  _________________ to protect the forest.

A. use fewer wood products            B. plant more trees      

C. blame the local people              D. protect the soil
