We give a computer instructions 1 putting a program into it．The program is 2 a human being, and it is essential that the human does not make a mistake．If we want a computer to do different jobs, we 3 give it different programs．
Is a computer cleverer than I am?
The answer 4 this question is, for the time being,‘No’．Your brain can understand the meaning of things better and create new ideas． 5 , one day computers may be able to do most things that a human brain can do and do them better．They may be better than doctors, judges and teachers at doing their jobs．
If this is true, it 6 interesting questions．What will happen 7 us if computers can do our jobs?How will we spend our lives? Will we have nothing to do? Computers may change our lives．But will they make 8 better?
CD-ROMs
Many of today's computers have CD-ROM drives．A CD-ROM can hold over 300,000 pages of writing, and can also contain pictures and sound．Thus, 9 , you can use your computer to read about a famous person in history such as John F Kennedy, and you can see a photograph or video of him, and even listen to him speaking．Some people think that CD-ROMs will 10 be more popular than books．
There are many things you can do to improve your memory．Among them are various memorizing methods as well as taking special care of your health．
1 is important that you regularly stimulate your brain to make your memory more efficient．You 2 do this by doing activities that you do not normally do and by changing your daily habits． 3 a new skill helps your brain to develop．When trying to memorize 4 , you should focus your attention because this will lower your chances of making accurate memories．
An excellent 5 to help is to link information with pictures．These are referred to as mnemonic techniques(记忆术)．Try to see the images in your mind．Taking notes, being organized and keeping a diary will 6 be useful tools．
7 food and plenty of vitamins are essential for your memory to work properly．Drinking a lot of water also helps maintain your memory．You must allow your brain to have 8 sleep and rest．When you are asleep, your brain stores memory．Not enough sleep can, therefore, cause 9 with storing information．In addition, being tired will stop you from being able to concentrate well．Caffeine in tea and coffee are very 10 at preventing sleepiness and helping concentration, 11 they can also cause problems with memory．
