  Google and Toyota have worked together to create a new smart car. It can run on the road without a driver. It drives itself. The self-driving car hasn’t been on sale to the public, so we don’t know how much it costs. Another thing most people want to know is whether it will be safe enough to run on the road.

  The self-driving car uses electricity as its power, and it can’t drive very quickly—the top speed would be 25 miles per hour. It is actually controlled by a computer system (系统) on the car. The system keeps on collecting information by some video cameras inside the car and a LIDAR sensor (激光雷达传感器) on top of it. A computer processes the information and decides what to do. “The self-driving car has only buttons (按钮) for go and stop, so it’s very easy to use,” an engineer of Google says. “And what’s more, it will make car accidents less and make the world a safer place.” The self-driving car has driven hundreds of thousands of miles in California, and it has only gotten into two accidents by human mistake.

  According to CNN, self-driving cars will also help to reduce (减少) the number of cars in big cities. “Self-driving cars would be able to send you to the workplace and then pick up another person instead of stopping in a parking lot.”

  Kenya, a country in East Africa, is known for its amazing wildlife, especially lions. However, over the last decade (十年) the number of lions has decreased from 10,000 to over 2,000. Most of them were killed by the local people because they had to do so to protect their cows.

  As well as the cows, wild animals should be protected. Now because of a creative idea thought of by a young boy, this problem can be solved peacefully.

  At the age of 11, Richard Turere was put in charge of the family’s cows. The local people think this job is an honor since cows are considered the family fortune.

  The only problem was that their land was next to Nairobi National Park, home to the largest number of lions in the world. As a result, the cows were often eaten by the hungry lions.

  Richard noticed that when he walked around the cows with a flashlight, the lions kept away because they were afraid of humans and the flashlight. So he decided to create an automated (自动的) flashlight. Richard tied some bulbs (灯泡) from broken flashlights around the cow stockade (栅栏). Under an automated lighting system, the bulbs flashed one by one, just like someone walking around with a flashlight that could keep lions away. 

  Since Richard’s invention was put to use, none of Richard’s cows has lost. As it only costs $10 to make this simple device, it can be widely used in Kenya in the future.

  ( )33. How many lions died during the last decade?

  A. About 2,000. B. About 8,000.

  C. About 10,000. D. About 1,200.

  ( )34. Richard wanted to make an automated flashlight because     .

  A. he wanted to became famous

  B. he had lots of broken flashlights

  C. he found lions were afraid of humans and flashlights

  D. he wanted to make the night as bright as the day

  ( )35. How did the automated flashlight drive lions away?

  A. By making loud noise.

  B. By producing strong light that could kill lions.

  C. All the bulbs flashed at the same time.

  D. Its bulbs flashed one by one.
