8．Want to stay away from colds？Put on a hap py face．
Compared to unhappy people，those who are cheerful and rel axed are less likely to suffer from colds，according to a new study．It's possible that being happy helps the body fight illnesses，say the researchers from New York University．
"It seems that positive feelings may reduce the danger of illness，"said the study's chief researcher Sheldon Cohen．In an earlier study，Cohen found that people who were cheerful and lively caught coughs and colds less often．People who showed feelings were also less likely to tell their doctors that they felt ill．
In this study，Cohen's interviewed 193 adults every day for two weeks．During the interviews，the people told researchers about the happy or sad feelings they had that day．After the two weeks，the people were given colds by doctors and had to stay alone in a room for six days．
   The result showed that everyone in the study was equally likely to get ill．But for people who said th ey felt happy during the research period，their illness was less serious and lasted for a shorter time．
Cohen believes that when people experience positive feelings，their body may produce a chemical that helps fight illness and disease．So if you are worried abut your health，look on the bright side more often．

7．At first，the earth's surface layer （层） was made up of huge blocks of hard，solid rocks．Then slowly，the rocks broke up into smaller and smaller pieces．Finally stones，pebbles （卵石） and grains of sand were formed．Many sorts of plants and animals lived and died on the surface of the earth．Their remains mixed up with the stones，pebbles and formed soil．The outmost layer of the earth is soil．
There are many ways in which large pieces of rock break into smaller ones．Wind，water，heat and cold help to break up rocks．When winds blow grains of sand against a large rock for a long time，the softer layers of the rock are slowly worn away．These leave holes and cracks in the rock，which become bigger and finally the rock breaks up into smaller pieces．
The moving water of streams and rivers also helps to break up rocks．As the water moves along，it carries with it small pieces of rock．These rub the larger ones．Thus，the larger rocks are worn down to smaller pieces．
The heat of the sun is also helpful to breaking up rocks．When the sun shines，the rocks become very hot．If these rocks are suddenly cooled，they may crack．Ice also plays a part in making soil．Water in the cracks can turn into ice in cold weather．As this happens，it becomes bigger and the cracks become wider，and finally break into smaller pieces．

6．Popeye the Sailor first became a popular cartoon in the 1930s．The sailor in that cartoon ate lots of spinach to make him strong．People watched him，and they began to buy and eat a lot more spinach．Popeye helped sell 33 percent more spinach than before!Spinach became a necessary part of many people's diets．Even some children who hated the taste began to eat the vegetable．
Many people thought that the iron in spinach made Popeye strong，but thi s is not true．Spinach does not have any more iron than any other green vegetable．
People only thought spinach had a lot of iron because the people who studied the food made a mistake．In the 1890s，a group of people studied what was inside vegetables．This group said that spinach had ten times more iron than it did．The group wrote the number wrong，and everyone accepted it．
Today，we know that the little iron there is in spinach cannot make a difference in how strong a person is．However，spinach does have something else which the body needs-folic acid．It is interesting to point out that folic acid can help make a person strong．Maybe it was really the folic acid that made Popeye strong all along．
