A、Force ourselves to remember things. B、Practice and exercise consciously. C、Never stop learning. D、Try hard to remember things.

Many of us often complain that we cannot remember things or easily forget things, however, (32)memory, they say, is a matter of practice and exercise. If you have the wish and really make a conscious effort to remember things, then you can quite easily improve your ability to remember them. (35)But even if you are successful, there are times when your memory seems to play tricks on you. It often happens that we remember things that did not really happen. (33)One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remembered locking it carefully the night before. What’s more, memory "tricks" work the other way as well. Once in a while, we remember not doing something and then find out that we did it. One day last month, for example, I was sitting in a barber shop waiting for my turn to get a haircut, and suddenly I realized that I got a haircut two days ago at the barber shop across the street from my office. Frequently, we seem to find something funny and amusing in incidents caused by people’s forgetfulness or absent-mindedness. (34)Stories about absent-minded professors have been told for years, and we never get tired of hearing new ones. (35)Unfortunately, however, absent-mindedness is not always funny. There are times when "tricks" of our memory can cause us great trouble.
