16．A Nobel Prize is considered by most people one of the highest international honours a person can receive．As you know，the prizes were started by a Swede called Alfred Nobel．He was born in Stockholm，the capital of Sweden．Alfred Nobel was a great scientist．He made two important inventions，and so he became very rich．Although he was rich，Nobel was not a happy man．He never married or had children．Also，he was a sick man during his large part of life．When he died at the age of 63，he left a fund of﹩9，000，000．The money was to be used in giving prizes to those who made great achievements in physics，chemistry（化学），medicine and literature（文学），and for world peace．The first Nobel Prizes were given on December 10，1901，five years after Nobel's death．Since then many famous people from all over the world have been given Nobel Prizes for their achievements．
      Each prize has three parts．The first part is a gold medal．Second，a winner of a Nobel Prize is given a certificate saying that he has been given the prize．The third part of the prize is a large amount of money about﹩40，000．
Often a prize is given to just one person，but not always．Sometimes a prize is shared．It may be given to two or more people who have worked together．It is also sometimes true that a prize is not given at all if there is no great achievement．In 1972，for example，no Nobel Peace Prize was given．

63．When was Alfred Nobel born？B
A．In 1938．   B．In 1833．   C．In 1896．   D．In 1906．
64．When he died，Nobel left a large amount of moneyD．
A．to his wife                            B．to his children
C．for helping the poor people in Sweden   D．for setting five prizes．

3．There is an old saying in English，"Laughter is the best medicine"．Until recently，few people took the saying very seriously．Now，however，doctors have begun to study laughter and the effects （作用） it has on the human body．They have found evidence that laughter really can improve people's health．
Tests were carried out to study the effects of laughter on the body．People watched funny films while doctors checked their heart rate，blood pressure，breathing and muscles．It was found that laughter has similar effects to physical exercise．It increases blood pressure，the heart rate and the rate of breathing．It also works several groups of muscles in the face，the stomach and even the feet．If laughter exercises the body，it must be helpful．
Other tests have shown that laughter appears to make the effect of pain on the body less．In one experiment doctors produced pain in groups of students who listened to different radio programs．The group which could bear the pain for the longest time was the group which listened to a funny program．The reason why laughter can make pain less seems to be that it helps to produce endorphins （内啡肽） in the brain．These are natural chemicals which make both stress and pain less．
There is also some evidence to suggest that laughter helps the body's immune system-that is the system which fights infection （感染）．In an experiment，one group of students watched a funny video while another group served as the control group-in other words，a group with which to compare the first group．Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells-the cells which fight infection．
As a result of these discoveries，some doctors and psychiatrists （精神病专家） in the United States now hold laughter clinics，in which they try to improve their patients'condition by encouraging them to laugh．They have found that even if their patients do not really feel like laughing，making them smile is enough to produce good effects similar to those caused by laughter．

In China，cloth and knives were used as money．Elephant tusks（牙），monkey tail and salt were used in some parts of the world．Rice was also a kind of money used by the people in some islands（岛）．Some animals were used as money，too．

20．Maybe you know floods，earthquakes，sandstorms and so on．But have you heard of typhoons？
Typhoons are some of the worst storms，usually around the Pacific Ocean and the South China Sea．Most happen in July，August and September．
How does a typhoon happen？When lots of sea water gets hot in the summer sun，it evaporates （蒸发）into the air．This makes the air hotter．When the air gets warm enough，it starts to move higher up into sky．Then cooler air around it rushes in．It fills the space that is left．After the air gets warmer，it starts to move quickly，making wind．The wind goes in circles（圆圈）and it keeps moving higher in the sky．The warmer the air gets，the quicker the wind moves．And when the wind moves faster than 30metres a second，a typhoon begins．
A typhoon has two parts，one is called the"eye"．In the eye，the wind does not move so fast．The other part is the wall of clouds around the eye．Here are the strongest winds and hardest rains．
Typhoons are very dangerous．In November this year，Typhoon Haiyan killed 5500people in Philippines．More people are missing．
What to do when a typhoon hits？
•Stay inside．Close all the windows and stay away from them．
•Try to bring all of your things inside．Strong winds could even blow away your bikes!
•Listen to the radio or TV for important information．
