Eat like a king in the morning, a prince at noon, and a peasant at night. This saying is all about the importance of breakfast. And now scientists can tell us just why it’s so important. According to a study carried out at Imperial College London, UK, skipping the first meal of the day not only means you eat more at lunch, but also that your brain wants to find more unhealthy foods.

The study suggests that there is a special part of our brain called the orbitofrontal cortex (眶额皮层), which plays an important part in making choices about what we eat. It is used for identifying the taste of food, especially when skipping breakfast. It is more likely to target high-calorie foods when you’re on an empty stomach.

Scientists did an experiment on this. Dr Tony Goldstone from Imperial College London, scanned (扫描) the brains of 21 men and women, around the age of 25. On the first day, these people skipped breakfast before the scans. On the second day, they had cereal (谷物), bread and jam as breakfast. After the scan on both days, they had their lunch.

When the volunteers had skipped breakfast, they ate around 20 percent more at lunch, compared with days when they had eaten breakfast. Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods. “We believe that bit identifies the value of foods – how pleasant, how delicious something is,” Goldstone told The Guardian.

1.From Paragraph 1, we learn that _____.

A. scientists found out why eating breakfast is important

B. it’s easy to lose weight without breakfast

C. there’s no need to have good food for supper

D. eating breakfast makes your brain smarter

2.Which is the correct order for the experiment on the first day?

① The volunteers skipped breakfast.

② The volunteers had lunch.

③ The volunteers had a brain scan.

A.①②③ B.③②① C.①③② D.③①②

3.Which of the following is NOT true about the orbitofrontal cortex?

A. It is part of our brain.

B. It tells people to eat breakfast.

C. It decides which food we like.

D. It is active toward high-calorie foods.

4.Which of the following can be the title for this passage?

A. Breakfast still most important

B. Three meals a day

C. Experiments on breakfast

D. Researches on lunch

Doctor Seuss was the name used by Theodor Seuss Geisel, who was famous because of the books he wrote for children. They combine funny words, funny pictures, and social opinion.

Theodor Geisel was born in Springfield, Massachusetts in 1904. After graduating from Dartmouth College in 1924, he spent a year studying literature(文学) at Oxford University in England. When he returned to the United States in 1927, he hoped to become a writer of serious literature. But the economic depression(经济萧条) in the United States delayed his dreams of becoming a serious writer. In 1937, he wrote his first book for children, which is called “And To Think I Saw It on Mulberry Street.” However, a number of publishers refused to accept it. They said it was too different from ordinary books. A friend finally published it. Soon other successful books followed. Over the years he wrote more than forty children’s books, which were fun to read. Yet his books sometimes dealt with serious subjects including equality, responsibility and protecting the environment.

Doctor Seuss had a strong desire to help children. In 1954, Life magazine published a report about school children who could not read. The report said many children’s books were not interesting. Reading the report, Doctor Seuss decided to write books that were interesting and easy to read. To make his book easy to read, he used words with the same ending sound, like fish and wish.

In 1957, Dr. Seuss wrote “The Cat in the Hat”, in which he used less than two hundred twenty-five words. This was the number of words a six-year-old should be able to read. The book was an immediate success. Children loved it. Their parents loved it, too. Today many adults say it is still one of the stories they like best. The success of the book made him want to write more books for children. He started a series called Beginner Books, which remain well liked among children today.

In 1984, Mr. Geisel won a Pulitzer Prize for children’s literature. At that time he had been writing children’s books for almost fifty years. He was honored for the education and enjoyment his books provided American children and their parents, and his influence remains through the books he wrote. Experts say his books helped change the way American children learned to read.

1.What was Theodor Geisel’s dream when he returned from England?

2.What did Theodor Geisel decide to do after he read the report published in Life magazine?

3.Why did Theodor Geisel finally set his simple writing style?
