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）and emotional (有感情的）AI.

But today we tell about an invention called the soccket, that is a real soccer ball of energy. Julia Silverman explains that in fact the soccket is a portable generator (便携式发电机).Julin Silverman and Jessica Matthews developed the soccket as part of a group project for an engineering class at Harvard University.There are mechanisms (装置) in a soccket. When you kick, hit or throw it, energy is then kept in it by these mechanisms instead of disappearing into the environment.Then the user can put something directly into the ball, like a lamp, or a mobile phone charger (充电器) so that they can get energy from it.For every fifteen minutes of the game play, the soccket can provide enough electricity(电) for an LED lamp for three hours, and the ball can store(储藏) up to 24 hours electricity.The International Energy Association reported last year that nearly one and a half billion people in the world had no electricity to use, and most of them live in Africa, India and other countries in Asia.Julia Silverman and Jessica Matthews both had experiences in developing countries before they began the project. They knew that power shortages are a serious problem in really areas.Theres an energy crisis in the world. One out of every five people in the world dont have any electricity. And besides that, there are a lot of health problems because what people use instead of the electricity are harmful choices like kerosene(煤油) lamps, which produce a lot of smoke.Julia Silverman says the soccket ball is one small solution to a big problem.Jessica Matthews and Julia Silverman hope their soccket ball will shine more light on the problem of power shortages. It offers people a chance to put their energy into the worlds most popular sport and get some energy in return.22 .

The best title for the passage should be _.AThe only way to produce electricityBThe best way to solve energy crisisCA soccer ball that gives energyDAn invention changing the world三、根据首字母、中文提示填空根据句意及汉语提示完成下列句子，每空一词26 .
