Perhaps one of the most important differences is that human beings have the ability to think, to make new ideas. Humans can do this because we have a welldeveloped brain. The brain allows us to think, to invent an idea, and to remember it. The brain has three main parts. Each part does a different task, so each part is equally important. The cerebrum（大腦） is where you think, decide, remember, and feel. This is the large part on top of your brain. Under the cerebrum is the cerebellum (小腦 ). This part controls your muscles, so this part dictates your body movements. The third part, called the medulla（髓質(zhì)） , which controls a very important group of nerves. It is through these nerves that messages pass from your brain to your body. The medulla does not help you think. It tells the muscles in your body to work. For example, the medulla keeps you breathing, it makes your heart continue to beat, and it tells your stomach to digest the food that just ate. The human brain is a very plicated an. Each of three parts does different jobs, but actually no one knows for certain how the brain works. 1. A best title for this passage is ______________________ . A. Three Ways for Thinking B.
