Do you play a musical instrument? If so, you may be getting smarter. A recent study shows that taking music lessons can raise a person’s IQ.
Scientists studied 132 children in Canadian schools. At the beginning of the school year, these children took an IQ test. Then they were divided into four groups. One group took singing lessons. Another group took weekly piano lessons. The third group took classes in drams(戏剧). And the last group did no special activities at all.
At the end of the school year, the 132 children took an IQ test again. In all four groups, the average score went up. However, the piano players’IQs went up 7.0 points on average. The average increase for the other three groups was only 4.3 points.
The researchers say that the difference is small and it may not result in better grades for the piano players. However, they still consider the results important. Learning an instrument helps kids becomes better at concentrating and at memorizing things. Therefore, the researchers say, it may be good for brain development in young people.
If you have a chance to learn to play a musical instrument, never miss it. Remember it can make you smarter.

Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such as Star Wars (星球大战) . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made “brain”. Leading the robot revolution (革命)are industrial(企业) robots that work in factories. Industrial(工业) robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren’t as friendly and bright as those you saw in  Star Wars. But, their makers say, today’s home robots “walk”, sense objects(感知物体) in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect.
We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths(波长) of light, and hear certain sounds. That’s because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can’t. To understand what their sensing devices(传感器) pick up is a hard job. Remember, man—made brains handle(处理)information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like—using only zeroes and ones.
【小题1】 From the passage, we can see that factory robots _________.
A.help to improve other types of robots
B.are most active in industrial revolution
C.are playing a more important role than other types of robots
D.are the tallest type among robots
【小题2】 It seems that home robots are __________________.
A.more widely used than factory robots
B.less common than factory robots
C.capable of doing any kind of housework
D.free from making mistakes while performing(执行) duties
【小题3】 Robots may deal with information that humans can’t. Which of the following is not one of the reasons?
A.They do not have so many limits as humans do.
B.They have man-made brains.
C.They may be equipped with a special kind of sensing device.
D.They handle information by using zeroes and ones.
【小题4】The development of robots suggests that _________.
A.science and technology are developing fast
B.people are interested in new inventions
C.machines are more capable than humans
D.robots can be very interesting
