Potatoes are very popular today. But in the past this was not true. Potatoes grew in South America 5,000 years ago. But they only became popular in other places 200 years ago.
In the 16th century, the Spanish took the potato from South America to Europe. But the people
didn"t like this strange vegetable. Some people thought that their skins would look like the skin of the
plant if they ate the potato. So they only ate the leaves. This made them sick because there is poison
(毒药) in the leaves.
In the 1800s, people started to eat potatoes. Potatoes became the main food in Ireland. Then
something unlucky happened. In 1845, a disease killed all the potatoes in Ireland. Two million people
died of hunger.
Today each country has its potato dish. Germans eat potato salad, and the USA has the baked
potato. Of course, the French invented French fries.

There are some countries where people seem to be living nearly on top of each other because conditions
are overcrowded. Then there are others where it seems that hardly anybody lives. What influences this
unequal distribution of people? There are specific advantages and disadvantages of diving in a certain
area.

usual weather conditions in a region. Areas that have bad weather are generally less deal as places to live

way, but the disadvantage of the bitterly cold and windy conditions usually keeps people way. When it
comes to climate, warm conditions and a normal amount of rainfall are advantage that attract people.
Natural resources are things that we get from nature that help us survive. Each region offers different
resources, and therefore attracts different groups of people. People who enjoy the beach car make their
living by catching and selling the ocean"s many fish and other sea creatures. Those who prefer farming can

cheerful and relaxed are less likely to suffer from cold, 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(积极的) 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 positive feelings were also less likely to tell their doctors that they felt ill.
In this study, Cohen"s study 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 they felt happy during the research period , their illness was less serious and lasted for a shorter time.
Cohen believes that when people experienced positive feelings, their body may produce a chemical
that helps fight illness and disease. So if you are worried about your health, look on the bright side more

A smile will tell people around you that you are a kind and friendly person. However, many people
don"t smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn"t
have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence
because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others" teeth are damaged because
of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in
bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how
to take care of them.
Smiling can help you to feel more confident and make other people think of you as a more friendly
person. If" you want to keep healthy, you should not only smile but also laugh. An Indian doctor called
Kataria said that young children should laugh about 300 times a day, while adults should laugh between 7
