【题目】In Los Angeles, drivers spend sixty-one hours every year stuck in traffic. These drivers know all too well how bad the traffic can be. “There’re too many cars, and you can’t move around a lot.”

Professor Cyrus Shahabi also knows about traffic jams. He lives more than 65 kilometers from his office at the University of Southern California, in Los Angeles. He is always late even with the help of a navigation (导航) system.

He decided to develop a program called ClearPath for that. He says his program uses historical data to predict traffic conditions even before the driver leaves the house. “What’s unique (独特的) is that we use a lot of data that’s currently become available including traffic data, weather data, and we analyze that so that we can predict what’s going to happen in front of you when leave home.”

Professor Shahabi says his system does more than just answer current traffic conditions. With ClearPath, he says, a driver can decide what time he wants to leave, and ClearPath will give the fastest route. It looks at the entire road network, including surface streets as well as highways, before the driver hits the road. Professor Shahabi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.

“I always thought that Los Angeles had the worst traffic, but now I know that Shanghai, Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can immediately use this.”Professor Shahabi hopes to share this new technology with companies that already have navigation systems, such as Google and Apple.

【题目】The twentieth century saw greater changes than any century before: changes for the better, changes for the worse; changes that brought a lot of benefits to human beings, changes that p1man in danger. Many things caused the changes, b2, in my opinion, the most important was the progress in science.

Scientific research in physics and biology has vastly broadened our views. It has given us a deeper k3 of the structure of matter and of the universe; it has brought us a better understanding of the nature of life a4 of its continuous development. Technology in the application of science has made big advances that have benefited us in n5 every part of life.

The continuation (持续) of such activities in the twenty-first century will result i6 even greater advantages to human beings: in pure science — a wider and deeper knowledge in all fields of learning; in applied science — a m7 reasonable sharing of material benefits, and better protection of the environment.

Sadly, however, there is another side to the picture. The creativity of science has b8 (employ) in doing damage to mankind. The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet.

William Shakespeare said, “The web of our life is of a mingled yarn (纱线), good and ill together.” The above brief review of the application of only one part of human activities — science seems t9 ( prove ) what Shakespeare said. But does it have to be so? Must the ill always go together with the g10? Are we biologically programmed for war?
