You and your family are planning a picnic for tomorrow. But you want to 11 the weather forecast(预报) first to see whether there will be rain or not. Your father turns on the television and the family listens to the 12 make the weather report.
“It will be partly cloudy tomorrow morning, 13 clearing by early afternoon. The high tomorrow will be 35.”
As there will be no rain, the whole family feels 14 . Without the weather forecast, you would not know this, and you would just have to take your chances. But now you can plan your picnic 15 worrying whether it will rain or not.

Congress(国会) became 19 in Abbe's weather reports. They made Abbe a meteorologist (someone who studies weather conditions), and he 20 issuing (公布) forecasts three times a day.

Artificial intelligence(AI)(人工智能) is the ability of a computer program or a machine. The computer or the machine with AI can think and learn. It is also a field of study that tries to make computers “smart”. John McCarthy, a scientist, came up with(提出) the name “artificial intelligence” over 60 years ago. Many things such as learning and problem solving can be done by computers, though not in the same way as people do.
An unusual goal of AI research is to create special computer programs. They can learn, solve problems and think logically(逻辑地). At present, AI can successfully understand human speech, recognize(辨别出) human faces, operate self-driving cars and compete in some game systems like playing chess. However, some people consider(认为) AI a danger to humans if it develops too quickly. A famous British scientist also was not for this kind of technology.
Math is the basic language of AI. If students are good at math, they will be more likely to become successful AI designers(设计者) in the future. We need not only bright students but also average(普通的) students. As for(对于) average students, if they get enough math skills, they can also become successful AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.
Scientists hope to create creative(有创造力的) and emotional(有情感的) AI. The AI can possibly understand human feelings or create art. Many ways and tools have been tried to discover this wide and exciting field.
21. From Paragraph 1, we know that .( )
A. all problems can be solved by computers

A. math and art
B. art and technology
C. math and computer science
D. art and computer science
25. Paragraph 4 mainly tells us the scientists' about AI. ( )

Once a king got two nice falcons(猎鹰) from his son. He had never seen such beautiful falcons before. He loved them so much and he ordered the best falconer to train them to fly.
After several months, the king came to see how the training was going on. He found that one falcon had already been able to fly high in the sky, while the other one was staying on the branch(树枝) of a tree quietly without moving.
The king called all his falconers together and ordered them to try every way they could to make it fly. But none of them succeeded. One day, while the king was taking a walk in the forest, an idea came to him. He decided to find someone who knew the natural environment well to solve the problem. Then he sent for a farmer who lived in the forest into his palace to train it at once.
The next morning, the king saw the other falcon flying above in the sky freely. “It is unbelievable!” shouted the king. “How could you make it happen?”
The farmer replied, “It's very easy. I just cut off the branch where the falcon rested.”
It is always the same to humans. We all have “two flying wings” in our hearts as well, but we often seem not to notice them and stay where we feel safe and comfortable. We won't realize we can fly so high and freely until the “branch” we are resting on breaks.
26.Who was ordered to train the two falcons to fly at first? (不超过5个词)
27.Why did the king ask the farmer to train the falcon? (不超过15个词)
28.What did the farmer do to make the other falcon fly?(不超过10个词)
29. She s (建议) staying here for another day, and we all agreed.
30. To ask your friends d (直接的) questions is all right when they know you well.
31. It's i (不礼貌的) to speak loudly in the reading room.
32. Susan didn't tell me her a (地址), so I can't go to visit her now.
33. The mobile phone has a great i (影响) on our life.
