1．Secret codes （密码） keep messages private．Bank，companies，and government agencies use secret code in doing business，especially when information is sent by computer．
People have used secret codes for thousands of years．（36）DCode breaking never lags（落后） behind code making．The science of decoding and reading coded messages is called cryptography．
There are three main types of cryptography．（37）EFor example，the first letters are"My elephant eats too many eels"spell out the hidden message"Meet me．"
（38）GYou might represent each letter with a number，for example，let's number the letters of the alphabet，in order，from 1 to 26．If we substitute a number for each letter，the message"Meet me"would read"1 3 5 20 13 5"．
A code uses symbols to replace words，phrases，or sentences．To read the message of a real code，you must have a code book．（39）FFor example，"bridge"might stand for"meet"and"out"might stand for"me"．The message"bridge out"would actually mean"Meet me"．（40）AHowever，it is also hard to keep a code book secret for long．So codes must be changed frequently．

A．It is very hard to break a code without the code book．
B．In any language，some letters are used more than others．
C．Only people who know the keyword can read the message．
D．As long as there have been codes，people have tried to break them．
E．You can hide a message by having the first letters of each word spell it out．
F．With a code book，you might write down words that would stand for other words．
G．Another way to hide a message is to use symbols to stand for specific letters of the alphabet．

9．It is difficult for doctors to help a person with a damaged brain．Without enough blood，the brain lives for only three to five minute．More often the doctors can't fix the damage．Sometimes they are afraid to try something to help because it is dangerous to work on the brain．The doctors might make the person worse if he operates on the brain．
Dr．Robert White，a famous professor and doctor，thinks he knows a way to help．He thinks doctors should make the brain very cold．If it is very cold，the brain can live without blood for 30 minutes．This gives the doctor a longer time to do something for the brain．
Dr．White tried his idea on 13 monkeys．First he taught them to do different jobs，then he operated on them．He made the monkeys'blood go through a machine．The machine cooled the blood．Then the machine sent the blood back to the monkeys'brains．When the brain's temperature was 10 C，Dr．White stopped the blood to the brain．After 30 minutes he turned the blood back on．He warmed the blood again．After their operations the monkeys were like they had been before．They were healthy and busy．Each one could still do the jobs the doctor had taught them．

16．How Can I Fight Laziness？Lazy people will never gain anything in life．However，laziness can be defeated once a few changes have been made in your mind．
（36）D  Many people lack sleep constantly，since they stay up too late and get up too early to prepare for work．These people have little motivation once they arrive home．Laziness works hand in hand with a lack of motivation and a tendency to put off things．By adjusting your sleep schedule to provide a few more hours of meaningful rest，you can fight laziness throughout the day．
Another way to fight laziness is to change your mind from passive to active．Some people treat their lives as if they were pushed from task to task．Others take a more positive approach，viewing each task as a challenge they must overcome alone．（37）F
Some people fight laziness by removing the temptations（诱惑） that surround them．A television in the living room may provide entertainment，but watching too much TV often contributes to laziness．（38）E  Complete a few tasks and reward yourself with what you enjoy，such as a good dinner or a film．
    Laziness can also be a lasting problem at home．Couples and children may all have different energy levels，but laziness can be spread if not dealt with immediately．（39）B   Be the first to collect and wash dishes after a meal．Others in the home may eventually follow your example and perform their own task．It is difficult to practice laziness when you are surrounded by motivated（积极的） people．
