Alex is reading a book about AI, artificial intelligence(人工智能) . He finds the book a little difficult but very interesting. Though the word AI is very popular now, he enjoys reading it very much. He has learned a new idea about AI from the book.
When people ask AI a question,, it answers the question in a very short time. So people may feel that AI can think and answer questions as human beings do. Before Alex read this book, he believed this, too. However, this book says it will never happen. Actually, AI only uses a lot of information to get the best answer. So when it has more information, the answer will be much closer to the perfect one. AI technologies will be clever tools for human beings to use. This book also says almost half of our jobs will be done by AI technologies in the near future. People will soon find more AI technologies in our lives, such as checking the tickets, the price, people’s faces and fingers.
So, we believe that we will have much happier lives with these AI technologies around us.

9 . Imagine the situation. You are driving alone on a mountain. You have no, idea where you are. You passed the last house two hours ago. Then your car breaks down. 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 device（装置）may be able to help you. It uses satellites to find the users' position. It can find your position within 20 metres. A GPS cannot start your car, but at least you will know where you are.
The GPS (the Global Positioning System) is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put it in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes or boats. Some of these devices have electronic maps, so you know where you are. For example, they can tell you the name of the street in a city.
There are three parts of the Global Positioning System. The first part is the receiver. You can hold it in your hand or fix it into your car, plane, etc. The second part is a group of satellites orbiting （绕……轨道运行）the Earth. The third part of the system is a network of ground stations. They are all over the world. They control 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 phone. They are becoming cheaper and better. 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.

| B．the GPS can't be put in a boat or a plane |
| C．the GPS will be more and more expensive |
| D．the GPS includes a group of satellites |
| A．systems | B．ground stations | C．satellites | D．receivers |
| A．the history of the GPS | B．the shape of the GPS |

10 . Fresh green grass. Hundreds of colorful wild flowers. Water running into little pools. Birds making their homes in boxes. The 9, 500-square-metre Augustenborg Botanical Garden may look just like any other well-organized park but there’s a difference. It lies on the roofs(屋顶) of industrial and office buildings in the city of Malmo in Sweden.
Green roofs are not a new invention. And now they are getting popular again. The common roofs of a modern city have endless black surfaces with no life or water. Perhaps that's why a garden on a roof becomes such a perfect choice for more and more people.
Green roofs are not just pretty. They also help to moderate the city temperature. The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot. What is more, they play a part in making the cities hotter than the countryside around them, causing the "urban heat-island effect". On a green roof, however, with its plants and water, temperatures change only a little, as they do in a park. This can greatly cut the costs of heating and cooling in the building below.
Also, a green roof takes in rain water, and protects the city drainage(排水) system. ________. And small animals and birds can make their homes on it. Thanks to this, the city may become part of nature, rather than something completely separate from it.
While the cost of building such a roof can still be higher, it can be cheaper in the long term as a result of energy savings. And wouldn't it be wonderful to be able to walk out into a garden high above the city's noise and traffic, whether you're at school or in an office or just at home in a ten-floor block.
