【題目】A healthy mind

The brain is the most fascinating part of our body. Even though there has been all medical research, n______ really understands everything about it. Like the rest of our body, our brain needs to be cared for. The ways that we keep our mind healthy can be quite s______. Getting a good night’s sleep, eating a balanced diet and taking deep breaths are all important methods of looking after both your body and your brain.

Many people think their brain will slow down with age and their memory will get worse as a result. The t______ is, just like your body, you can also improve your mind. I’ve found I can improve my memory by i_____ what I need to remember. For example, if I’m going shopping and I need bread, milk and a birthday card for my brother, I form pictures of a loaf of bread, a carton of milk with a cow on the front and a birthday card with a football on it.

The same kind of method can be used with important dates. If you have a picture in your mind of a particular event, it’s much e______ to remember than just a number on a calendar.

Another way of improving your mind is to make sure you r______ visit new places and have new experiences. Traveling more often has much more long-term benefits than you would have ever expected. Personally I find learning English is a great way to keep the brain working, but communication with others in any language is important. Having a c______ is much better for your brain than staring at a computer screen or at other people talking on TV.
