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 (華爾街日?qǐng)?bào)).

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 early B.the body’s temperature needs time to rise

C.they have to take a shower first D.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 different B.And everyone’s body clock is almost the same

C.But everyone’s brain is different D.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.

4.What would be the best title for the story?

A.Research about time B.The best time to do things

C.Brain performance D.Different periods of a day

I will never forget my first English class. The teacher told us that his English name was Jason. It means a man who knows a lot. Then he asked all of us to think of an English name for ourselves. I thought about it for a long time. Then I got an idea-why didn’t I call myself Apple? I loved the fruit. I wrote the name on a piece of paper and gave it to Jason. Later, when Jason called “Apple”, three girls stood up at the same time.

The class laughed(大笑). Jason stopped them and said, “Girls, I’m sorry to say Apple is not really an English name. Would you like me to give you one?”

“BANG!” the door caused a big noise. It was just standing there, with Father standing on one side, and I on the other side.

We were both in great anger. “Never set foot in this house again!” stormed Father. With tears in my eyes, I rushed out of the flat and ran along the street.

The street lights were shining, causing rather sad-feeling. I walked aimlessly.

A young father who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree.

But now ... I don’t know whether it is because I have grown up or because Dad is getting old. We differ in our ways of thinking. He always puts his opinions and rules of behaviour on me. Whenever I do something wrong, he never allows it. We are just like two people coming from two different worlds. It feels like there is an iron door between us that can never be opened.

I walked in the streets, without a place in mind. My heart was frozen on this hot summer night. As I walked on, there were fewer and fewer people on the streets, until I had only the street lights to accompany me. When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.

I thought to myself: “Is Father waiting for me, or is he still angry with me?”

In fact, it was nothing. Perhaps, Dad was throwing away some of his old stamps. Perhaps he thought they were useless. I never had the courage to tell him that I liked collecting stamps. I can’t stand his words: “I can’t throw you away, let alone these old papers?”

All the lights were off except Father’s.

Dad was always like this. Maybe he didn’t know how to express himself. After shouting at me, he never showed any pity or any moments of feeling sorry. After an argument he has the habit of appearing silently in my sleep and then helping me under the covers.

This was how he always was. He has been a leader for so long that telling everyone else what to do has become his second nature.

The light was still on. “Am I wrong?” I whispered, maybe ... With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door, tears ran down my face. I suddenly realized that the iron door that I had imagined between us did not exist(存在) at all. Love — is second to none.

1.Which is the best order of the following according to what happened in the passage?

a. I opened the door and entered the house.

b. Sadly I ran out into the street.

c. I reached the place where I lived and saw my house still brightly lit.

d. I thought of my father’s kindness towards me.

e. I walked about in the street without any aim.

A.b—e—d—c—a B.b—e—c—d—a C.b—e—a—c—d D.b—e—c—a—d

2.What can we learn from the passage?

A.The father treats his son in an unfair way. B.The father is actually kind to his son.

C.The father is neither kind nor rude to his son. D.The father is always finding his son wrong.

3.This passage is mainly about ___________.

A.how the boy understand his father’s love B.where the boy went

C.what made a father angry D.why the boy left home
