One pleasant New Year morning, Edward got up and dressed himself in a hurry. He wanted to be the first to wish a happy New Year.

He looked in every room, and shouted “Happy New Year” to every one of his family. Then he ran into the street to repeat it to those he met. When he came back, his father gave him two new dollars. His face lighted up as he took them. He had wished for a long time to buy some nice books.

As he ran down the street with a light heart to the bookshop, he saw a poor German family—the father, mother and three children walking in the cold wind.

“I wish you a happy New Year,” said Edward, as he was happily passing on. The man shook his head. “You do not belong to this country?” asked Edward. The man shook his head again, because he could not understand or speak English. But he pointed to his mouth, and to the children, he seemed to say, “These little ones have had nothing to cat for a long time.”

Edward quickly understood that these people were poor and in trouble. He took out his dollars and gave one to the man, and the other to his wife. They said something in their language, which mean, “Thank you very much, and we will remember you forever.”

【题目】 What time of day do you feel most alert (清醒的)? Are you more of a morning person? Or does your brain need a few hours to get going? A lot of research suggests that we should pay attention to our body clock. It can tell us what time of day we are best able to perform, according to the Wall Street Journal (华尔街日报).

For example, many people work best later in the morning. This is because the body’s temperature takes time to go up through the day. Taking a warm shower when you wake up can help speed this up. And when the sun comes out for a few hours, it may help a lot, too.

▲ . Morning people will rise early and work better early in the day. Evening people will wake later but their brain will work better toward the end of the day.

Research shows that we’re better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it’s better to exercise later in the day.

Between noon and 4 pm, people begin to get distracted (思想不集中的). This is partly because our brain becomes less alert after we eat a big meal. Research also shows that we become sleepy around 2 pm.

Finally, it is best to eat during our active periods. This allows our body to burn calories better and stops our blood sugar levels from getting too high. So a suitable time can help us keep healthy. It’s necessary for us to know about it.

【1】Why do many people perform best later in the morning?

A.they can’t get up very earlyB.the body’s temperature needs time to rise

C.they have to take a shower firstD.that’s when the brain wakes up

【2】Which of the following is the best to fill in the blank?

A.But everyone’s body clock is differentB.And everyone’s body clock is almost the same

C.But everyone’s brain is differentD.And everyone’s brain is almost the same

【3】According to the research, which of the following is TRUE?

A.It’s better to do exercise in the afternoon.B.We perform better after eating a big meal.

C.Sleeping at 2 pm is not good for our health.D.Our body burns calories better at night.
