Joyce wanted to have a feature about memory in the school newspaper. She and her editors all agreed to write short articles on this topic.
I read in a book that we have a short-term memory and a long-term memory. When people get old, their short-term memory becomes weaker, but they can still remember things that happened a long time ago.
My grandad told me a joke about memory. He said, ‘When you get old, three things start to
go wrong. First, you start to lose your memory. And I can’t remember what the other two things are!’
Memory is essential for life. I saw a programme on television about a man who had had an accident and injured his brain. Afterwards, he could not remember anything for longer than a few minutes.
His wife visited him in hospital every day, but he forgot her visits a few minutes after she left. He was often angry with her because he thought that she never visited him. It was very sad.
One basic way of improving your memory is to use the link method. If you want to memorize something, you should make a picture in your mind. If the picture is silly, strange and colourful, you will remember it better. For example, I am
In the Guinness Book of Records, we can find some amazing stories about memory. For example, Gou Yanling from Harbin in China has memorized more than 15,000 telephone numbers. And Dave Farrow from America remembered the correct order of 2,704 playing cards, after seeing them just once.
Memory is connected with our feelings. For example,
if someone says ‘This is a spider’, and then puts a large spider on your hand, you will probably remember the word ‘spider’! When something dramatic happens, we usually remember it well, and we also remember where we were and what we were doing. For example, most people in China can remember where they were when the opening ceremony of the 29th Olympic Games was held in Beijing in 2008.

if sentences: actions with possible results
We also use if sentences to talk about results that will probably happen. In these sentences, the verb tenses are different. The verb in the if clause (first clause) is in the simple present tense. The verb in the second clause is in the simple future tense.
If I invent a kind of special brain food, everybody will buy it.
The if clause talks about the possible action.
The second clause talks about the result that will probably happen.
