1. (2022八下·深圳期末) 阅读下列短文，从下面每题的A、B、C、D四个选项中选出最佳选项。

Everybody has a brain, but not many people know how the brain works. Some people believe that the brain is like the hard disk of a computer. We use it to store files—pictures, words, text, sounds and so on. Others compare the brain to a huge cupboard with lots of shelves and boxes in it. We put information into these boxes and hope to find it again later. However, the brain is not a computer disk, and it is not a cupboard, either.

Look at the picture here. It looks a bit like weeds (杂草) in a garden, doesn't it? The picture actually shows a child's neocortex一a part of the brain that controls sight and hearing. You can guess what happens—more “weeds" grow as the child gets older. Scientists call these neuronal networks (神经网络). The networks grow around our neurons. What makes them grow? Learning! "Leaning causes brain change, " says Professor James Zull from Case Western Reserve University in Cleveland, Ohio, USA. " Without learning, nothing changes in the brain. For every new word you learn in your English lesson, every problem you solve in maths, and every new song you learn to sing, a neuronal network grows in your brain and the brain changes. '

The more neuronal networks we have, the better we can think and the better we can remember tings. You may wonder if there is anything you can do to make the networks in your brain grow better. Professor Zull says, "Yes there is" He says that brain change is the strongest when you are interested in and like what you are learning. You are in control of what you learn and you get a challenging task that makes you feel good and develops your brain. So you can become cleverer as you learn more.
