If you go to a fast food restaurant or a snack bar, you will probably see a lot of teenagers．Today, many teenagers are overweight(超重的）, and some of this is because of their bad eating habits．Most teenagers love food with a lot of fat, oil, salt, and sugar．People often call this type of food “junk food”．

　　But bad eating habits go beyond fast food．Many teenagers find it difficult to eat healthily．Some don’t have breakfast before they go to school．During the day, some don’t have a proper meal for lunch．In a recent survey at one school, scientists found that over two－thirds of the students didn’t follow a healthy diet．Nearly half of the students didn’t like vegetables, and many of them didn’t like to eat fruits．They preferred to eat food with a lot of salt, sugar, or fat．

　　Parents today also worry about their children’s diet．Some doctors give the following advice．

●Teenagers shouldn’t eat too much junk food．

●Teenagers shouldn’t eat food with too much salt．Salt can cause high blood pressure in the future．

●Teenagers should eat food with less fat, oil and sugar．

●Teenagers need to eat some fruits and vegetables every day．Fruits and vegetables are rich in vitamins (維生素) and have little fat．

It sells all kinds of souvenirs about pandas. There are panda toys. There are also T-shirts and hats with pandas on them. It’s the last stop for visitors in Pandasia.

Do you know any 9-year-olds who have started their own museums? When Theodore Roosevelt(羅斯福) was only nine, he and two of his cousins opened the “Roosevelt Museum of Natural History”. The museum was in Theodore's bedroom. It had a total of 12 specimens(標本). On display were a few seashells, some dead insects and some birds' nests. Young Roosevelt took great pride in his small museum.

Born in New York in 1858, Theodore Roosevelt was not always healthy. “I was a sickly, delicate boy，” he once wrote. Roosevelt had a health condition called asthma(哮喘). He often found it hard to breathe. Instead of playing, he observed(觀察) nature and then read and wrote about it. Roosevelt's interest in nature sometimes got him into trouble. Once, his mother found several dead mice in the icebox. She ordered him to throw them out. This was indeed “a loss to science”， Roosevelt said later.

Because Roosevelt was often sickly as a boy, his body was small and weak. When he was about 12, his father urged him to improve his body. Roosevelt began working out in a gym. He didn't become strong quickly. But he did decide to face life's challenges with a strong spirit. That determination stayed with Roosevelt his whole life. And finally his body did get strong. As an adult, he was an active, healthy person. He enjoyed adventures and loved outdoors. In 1900, at the age of 41, Roosevelt was elected Vice President(副總統(tǒng)). A year later, President McKinley was shot and killed. Roosevelt became the 26th president of the USA. At 42, he was the youngest leader the country had ever had.

1.What is the main idea of the first paragraph?

A. Roosevelt's museum had 12 specimens. B. Roosevelt had a small museum as a boy.

C. Roosevelt was a brave man. D. Roosevelt had two cousins.

2.Which of the following tells about Roosevelt as a boy?

A. He liked playing outdoors sports. B. He was interested in observing nature.

C. He became the President in 1901. D. He was a healthy person full of energy.

3.It can be inferred(推斷) that________．

A. Roosevelt's mother liked mice B. everyone with asthma is small and weak

C. Roosevelt followed his father's advice D. working out in a gym is a waste of time

4.In which book might you find this passage?

A. Improving Your Body. B. Living with Asthma.

C. Small Museums of Natural History. D. The Childhoods of America's Presidents.
