Some people can stay up all night and still get work done the next day. I’m not one of them. After a night without enough sleep, I feel sleepy. I have trouble remembering things. And all I want to do is to go back to bed and sleep.
How do you feel after you’ve stayed up late to finish schoolwork? Or the day after a slumber(睡眠) party? Scientists now say that your answers to these questions may depend on your genes, which tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms.
A new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.
The period3 gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.
Scientists studied 24 people who had to stay awake for 40 hours straight. Then they took tests that measured how well they could remember lists of numbers.
Results showed that the people with the short form of period3 performed much better than those with the long form did. In both groups, people performed worst in the early morning. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off(瞌睡).
People with long period3 gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form period3. What about you?

A. the size of your brain         B. the kind of genes you have
C. your health                 D. your will

Florence Nightingale(南丁格尔) was born in a rich family. When she was young she took lessons in music and drawing, and read great books. She also traveled a great deal with her mother and father.
As a child she felt that visiting sick people was both a duty and a pleasure. She enjoyed helping them.
At last mind was made up. “I’m going to be a nurse,” she decided.
“Nursing isn’t the right work for a lady,” her father told her.
“Then I will make it so ”, she smiled. And she went to learn nursing in Germany and France.
When she returned to England, Florence started a nursing home . During the Crimean War in 1854 she went with a group of thirty eight nurses to the front hospitals. What they saw there was terrible. Dirt and death were everywhere to be seen — and smelled. The officer there did not want any woman to tell him how to run a hospital, either. But the brave nurse went to work.
Florence used her own money and some from friends to buy clothes, beds, medicine and food for the men. Her only pay was in smiles from the lips of dying soldiers. But they were more than enough for this kind woman.
After she returned to England, she was honored for her services by Queen Victoria. But Florence said that her work had just begun. She raised money to build the Nightingale Home for Nurses in London. She also wrote a book on public health, which was printed in several countries.

In most languages, a greeting is usually followed by “small talk”. Small talk means the little things we talk about at the start of a conversation. In English-speaking countries people often make small talk about the weather. “Nice day, isn’t it?” “Terrible weather, isn’t it?” But there is something special about small talk. It must be about something which both people have the same opinion about. The purpose of small talk is to let both people agree on something. This makes meeting people easier and more comfortable. People usually agree about the weather, so it is a safe topic for small talk. But people often disagree about religion(宗教) or politics(政治) so these are not suitable topics for small talk. The topics for small talk also depend on where the conversation is taking place. At football matches, people make small talk about the game they are watching. “Great game, isn’t it?” At bus-stops, people may comment on the transport system. “The bus service is terrible, isn’t it?”
Small talk is ________.

A.a kind of conversation with short words

I have a neighbor we call “Happy”. I have never seen her angry at anything and never heard her say a harsh (苛刻) word to anyone or about anyone.
Happy and her husband Ben, 70, have a huge garden. They spent many happy hours together working on it. Most of the neighbors watched interestingly as Ben doubled the size of their garden. As the cost of food climbed faster than Ben’s beans, we all wished we also had such a large garden. As the rest of us spent our dollars at the market, Happy could be seen picking beans in her back yard.
Last month, Happy and Ben invited most of the neighborhood over for an “all-day food feast”. We were told to bring gloves and arrive very early in the morning. We didn’t know what was about to take place.
By 9:00 am, there were nine of us in the garden picking tomatoes, beans, okra, and squash. By 10:00 am, there was lots of laughter. We shared a lot of stories. By five o’clock, everyone was a little drunk from the wine and beer. After dinner, we played games. As we were leaving, Happy and Ben handed each of us a shopping bag filled with the bounty(收成)of the day, already packaged and frozen. What a delightful gift!
Well, the point wasn’t so much about the food. The true gift was a day of friends enjoying one another’s company(陪伴). None of it would have happened if it had been for Happy and Ben’s garden. Now they have a blog about gardening in case we decided to plant a garden. And I am so proud of my tomato plants!

A.don’t like spending time with others
B.sometimes quarrel with each other

D.are a generous and warm-hearted couple

“BANG!” the door caused a reverberation (回声). 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 welling up in my eyes, I rushed out of the flat and ran along the street.
The street lights were shining, causing rather sad-feeling. I wandered 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 put his opinions and codes of behavior on me. Whenever I do something wrong, he never admits 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 wandered the streets, without a destination in mind. My heart was frozen on this hot summer night. As I walked on there were fewer and fewer people on th e streets, until I had only the street lights to keep me company. 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 outrageous(蛮横的)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 mercy or any moments of regret. After an argument he has the habit of creeping up in my sleep and then tucking me underneath 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 cheeks. I suddenly realized that the iron door that I had imagined between us did not exist(存在) at all. Love—it second to none.
Decide 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.

We often hear people talking about a generation gap (代沟). The name is new, but the idea is old. Young people and their parents don’t understand each other. The world has always kept changing. During the second century after Christ a wise man said, “Bury me on my face because in a little while everything will be turned upside down.”
There has always been a gap between generations, but more people talk about it now. Old Mr. Ellis thinks he understands what has happened.
“When I was a boy, I thought the world was a beautiful place. My life was very pleasant. But when I was older, I learned about people who were treated badly and people who didn’t have enough to eat. I wanted to help them, and I married a girl who wanted to help them, too. We went to meetings and talked a lot, but it didn’t seem to make much difference. ”
“Our children grew up in a world at war. They didn’t know when the fighting would stop. They wanted their children to have nice clothes and toys. They didn’t want to think about the future. They thought nothing could be done about it.”
“Now I have grandchildren, and they have their own ideas. They are trying to make the world better. They are trying to help other people. They’re making people listen to them. I am proud of their generation.”
