Perhaps you have complained about it because you thought it took you much playtime. But now you’d better thank your parents for their time and money spent on your musical training. A recent study suggests music lessons can make children have better memories than their peers (同龄人).‎ The Canadian study showed that after one year of musical training, children did better on a memory test than those who didn’t take music lessons.‎ The researchers made the children aged between 4 and 6 into two groups — one group of children took music lessons outside school, and the other didn’t take any musical training. In one year, they took four tests in different times. The results showed brain (大脑) development changes at least every four months.‎ The children taking music lessons not only did better in musical listening but also made faster progress in other ways, such as reading, writing, math and IQ.‎ People say music is the good medicine (良药) for a broken heart. Now it seems music can also help us to improve our memories. We are sure to find more and more in the wonderful world of music.‎ 根据材料内容选择最佳答案,并将其标号填入题前括号内。‎ ‎( )6.

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.”‎ 根据材料内容选择最佳答案,并将其标号填入题前括号内。‎ ‎( )11.
