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 (眶額皮層), 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 (掃描) 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

① The volunteers skipped breakfast.

② The volunteers had lunch.

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?

C. Experiments on breakfast

D. Researches on lunch

EUROPE is home to a variety of cultural treasures. Lonely Planet has offered pairs of cities for culture-hungry but time-poor travelers.

London and Paris

It takes you about two hours to travel from London to Paris by Eurostar, a high-speed railway service. The two capital cities have been competing in fashion, art and nightlife for decades—but each secretly looks up to the other.

No one can doubt the grand and impressive beauty of Paris’ Louvre Museum, but if you want to save money, you cannot skip the British Museum free to visit. Compared with London, Paris has more outdoor attractions, such as the beautiful green walkway La Promenade Plantee.

In Paris, you’ll see diners linger (逗留) over red wine. While in London, you can try some afternoon tea, eat fish and chips or salted cake.

Vienna and Bratislava

Austrian capital Vienna and Slovakia city Bratislava are an hour apart by train. But since they are linked by the Danube River, the best way to travel is by ship. A tour of the two cities is the perfect way to experience everything from 17th century’s Habsburg dynasty splendor to sci-fi restaurants.

Vienna is famous for Mozart and imperial palaces. You can appreciate the perfect blending of architecture and nature in the grand Scholoss Schonbrunn Palace, and reward yourself with a cup of Vienna coffee, which has made its way to the world’s cultural heritage list.

Bratislava is best known for its fine dining—the remarkable UFO restaurant. You can enjoy a meat–laden dinner here in an amazing setting.

1.What’s the relationship between London and Paris according to the text?

A. They help each other.

B. They admire each other.

C. They attack each other.

D. They don’t like each other.

Dear Manager，

I am an exchange student from the UK. Yesterday, I went to your cinema to see a film. The film was very well, but I did not enjoy it because there were some problem in the cinema.

First, the film was delayed as there were so much advertisements at the beginning. It was rather annoyed. Second, the sound of the film was too loud that I could hardly bear. The EXIT sign could not be seen clearly, which presented lots of potential safety dangers. If something terribly should happen, it will be difficult for people to get out quickly.

As a visitor to your city, I'm disappointed with my experience in your cinema. I am writing a letter in the hope that you can consider about these problems and make some improvement.

Yours faithfully，

Jack

Our house was directly across the street from the clinic entrance of John Hopkins Hospital in Baltimore. We lived downstairs and rented the upstairs rooms to the patients at the clinic.

One evening as I was fixing supper, there was a knock at the door. I opened it to see a truly awful-looking man. He’s hardly taller than my eight-year-old son. “Good evening. I’ve come to see if you’ve a room. I came for a treatment this morning from the eastern shore, and there’s no bus till morning.” He told me he’d been hunting for a room since noon but with no success. “I guess it’s my face…I know it looks terrible, but my doctor says with a few more treatments…” For a moment I hesitated, but his next words convinced me: “I could sleep in this chair on the porch. My bus leaves early in the morning.”

I told him we would find him a bed. When I had finished the dishes, I talked with him. He told me he fished for a living to support his five children, and his wife, who was hopelessly crippled (殘疾的) from a back injury. He didn’t tell it by way of complaint. Next morning, just before he left, as if asking a great favor, he said, “Could I come back and stay the next time?” He added, “Your children made me feel at home.”

On his next trip he arrived a little after seven in the morning. As a gift, he brought a big fish and the largest oysters (牡蠣) I had ever seen. I knew his bus left at 4:00 a.m. and I wondered what time he had to get up in order to do this for us.

In the years he came to stay overnight with us and there was never a time that he did not bring us vegetables from his garden. I know our family always will be grateful to have known him; from him we learned how to accept the bad without complaint when facing the misfortune.

1.Why did the author agree to let the man spend the night in his house at last?

A. Because the man said others refused to accommodate him.

B. Because the man said he would not cause much inconvenience.

C. Because the man said he had come from the eastern shore.

D. Because the man said he had been hunting for a room since noon.

2.How long would it take the man to travel from his home to Baltimore by bus?

A. About 1 hour. B. About 2 hours.

C. About 3 hours. D. About 4 hours.

3.From the text we can know that __________.

A. the author’s children were kind and friendly to the man

B. the man was fed up with his hard-work and his family

C. John Hopkins Hospital provided rooms for the patients to live in

D. the author and his family were thought highly of by his neighbors

4.The author’s family were grateful to know the man because __________.

A. he often brought them fish and vegetables from his garden

B. he paid them money for his staying

C. he taught them how to accept the bad without complaint

D. he stayed only overnight with the writer’s family
