1 . During the winter vacation,I was involved in an image-processing project. My task was to extract（提取）the shape of every cell from a(n)__ of microscope images. It seemed quite straightforward at first,but it turned out to be __.

Since I did not have any experience in image processing,I studied some basic ___on my own and started to use a very popular function library(函数库）called OpenCV. As the time was __,I just learnt to apply techniques without going into the mathematical rationale(原理）。As a result,I didn't complete the task in an efficient way and____lots of time.

Through this project,I got a good __ of the importance of studying the basic knowledge. I will probably ___to spend more time studying the theory before I ___another project. By learning their underlying mechanisms(机制），I will be able to ___the tools to suit my own needs. In this way,1 may achieve___ results.

Another challenge I met was about the brightness setting. When I sketched(勾勒）the __ of the cell by the computer,I first set the brightness value to 50,___that the computer could delete the dark places and extract the shape of the cell___. But it turned out that the standard didn't fit for every image. So 1____the brightness value to 30,but that didn't __ either. It was very hard to find a value that worked for all ____

From this,I began to appreciate human eyes. Our eyes ___the amount of light entering them automatically through a feedback system to achieve the best image representation,but computers are not that __. There is still so much that we don't know about the human body.

In summary,I think it is good for students to be involved in real projects___ they can begin to learn about various fundamental ___and get themselves ready for the future.

6 . “Are personal sad stories a must to win talent shows?” “Shouldn’t talent be judged on the basis of itself without needing a sad story of struggle to win?” These are questions Sanya Malhotra posed on a recent Facebook post.

This morning I came across this interesting post by Sanya Malhotra. She revealed that she loved dancing and dreamt of becoming an actress, but got defeated in “Dance India Dance” because her background story wasn’t sad and inspiring enough. That’s when she started doubting her artistic gift.

This really set me thinking. Why are people attracted to sob stories? Why do we always appreciate only those people who have achieved something after going through a lot of hardships?   Why does the headline of a newspaper “Taxi-driver’s Son Stands First In UPSC Exam” find more readers? I think it is because most people, who are in a similar situation, find it comforting that someone has succeeded with so many hardships. I know it is really very difficult for people with financial, health, or family problems to overcome obstacles and succeed. I really feel proud of them and I am often touched and inspired by their stories.

Now come back to what Sanya has said. I think this is a talent show rather than a story-telling competition. When it comes to a competition of singing or dancing or any fine arts, all the competitors should be judged without any bias (偏见). No one should lose because they don’t have a sad story of struggle to tell. It’s very unfair. They can be given opportunities otherwise, but should not be judged because of their stories.

Maybe, the TV channels do it to attract more viewers, because the most important element of any reality show is these touching stories. But as Sanya has said, it’s unfair to those who haven't such a story and are equally talented.

1. What do we know about Sanya Malhotra?

A．She entered a talent show.	B．She won “Dance India Dance”.
C．She had a sad story to tell.	D．She was rejected in a film.

2. From the second paragraph, we can infer that Sanya Malhotra________.

A．experienced many hardships	B．is a famous actress in Indian
C．has a great gift for gymnastics	D．used to be confident in her artistic talent

3. Which of the following headlines appeals to the readers most according to the passage?

A．A Millionaire Donated Money To Harvard University.

B．A Gifted Indian Teenager Won “Dance India Dance”.

C．An Armless Girl Was Admitted To Harvard University.

D．A Freshman Paid Off Loans By Getting A Part-time Job.

4. Which of the following is the best title of the passage?

A．Winners Should Be Determined By Public Judges

B．Sanya Malhotra Displayed A Great Artistic Gift

C．Competitors Should Not Be Judged By Sob Stories

D．Talent Shows Competitors Can Tell Their Stories

7 . The daughter of a friend of mine recently left university and entered into the world of work, taking on a temporary office job.At the end of her first week at work,she phoned home in tears.

＂It's horrible,"she complained to her mother,"there's no time to do anything else,I'm so tired. when I get home in the evenings that all I can do is watching TV.And then I have to get up early the next morning and do it all again!If this is what work is like,I don't want to spend my whole life doing it!"

We take it for granted that work must be a major part of our lives-in fact,for many people, it's the primary aspect of our lives.We define ourselves,and other people,by our job roles-"So what do you do?"-and measure our happiness in terms of how successful we are in these roles. Forty hours a week,48 weeks a year,for up to 50 years-not including traveling time,and the time we spend resting and recovering from the efforts of our working lives.

Of course,if you're lucky,you might have a job which is satisfying,which suits your interests and skills,and which you find challenging and thrilling.In that case,your job may provide you with what psychologists call"flow"-a state of intense(强烈的）absorption,which makes you feel busy and alive.Perhaps the majority of people aren't so lucky and do jobs which are repetitive and boring.But I would argue that,even if your job does provide you with"flow",work should just be an aspect of our lives.Working 40 hours a week makes our lives become constricted,so that we lose sight of whole vista(前景）of possibility.There's so much to learn in life,so many different ways to develop,so many activities to enjoy (including doing nothing),but while we spend so much time working it's difficult to find time and energy for these.

1. Why does the writer mention the daughter of his friend?

A．To introduce the topic.

B．To show his sympathy.

C．To confirm his opinion.

D．To raise the readers' interest.

2. What did the daughter of the writer's friend complain about?

A．The demanding boss,

B．The tiring work routine.

C．The unfriendly workmates.

D．The challenging goals.

3. Which of the following can best replace the underlined word"constricted"?

A．steady

B．complete

C．careful

D．narrow

4. Which of the following about"flow”will the writer agree with?

A．Most of the people have jobs that provide"flow",

B．People may work nervously even with"flow"in jobs.

C．People are encouraged to work actively because of"flow".

D．People are required to work harder once provided with"flow".

8 . I had been living with Dino and his family for ten days or so, who lived and worked in the rainforest. They were the “bad guys”, burning much of the western Amazon to tun it into cattle farms. They were also some of the nicest and warmest hosts. They are a family trying to survive in a very tough environment through hard work. Their view and understanding of the problems the Amazon faces are different from mine. I see the Amazon as an extraordinary valuable life that should be treasured and protected at all costs-the world needs it, and we all need it. However, the Dinos see the Amazon as a vast, lasting resource that feeds them. After talking extent win them, I realized their respect for it was as deep as my own: they just saw it very differently.

Cattle farming in the Amazon is perhaps mainly responsible for the fires we are seeing now. It is an industry of cutting forest, burning it and turning it to cattle farms. Fires spread throughout the Amazon every year as a result of that practice. Putting cattle on the land means replacing trees with animals that produce damaging levels of greenhouse gases. This is just about the most stupid thing humans can do.

One morning after a fire, I returned to the land. I felt as though I had seen the blue smoke from those blackened tree trunks that remained upright, which are memorials to human stupidity.

The problems the Amazon faces are perhaps more complex now than ever before, but they are curable. We need to decide where and how we appoint and apply values based on sensible economic models that favor both the farmer and the forest. One of the issues facing the Brazilian Amazon now is a loosening of rules by the current administration which has opened up more land for deforestation(毁林) and burning. This could be disastrous, both for the Amazon and the rest of the world.

1. What does Paragraph 2 mainly talk about？

A．The consequences of cattle farming.	B．The main cause of forest fires.
C．The causes of greenhouse gases.	D．The importance of cattle farming.

2. How did the author feel when returning to the land after a fire?

A．It helped the author recall his memory about the land.

B．It reminded us of our foolishness of destroying the land.

C．It's not surprising to see the land destroyed by the fire.

D．It's amazing to see the trees keep straight after the fire.

3. Which of the following statements is true?

A．The writer and Dino respected the Amazon equally in different ways.

B．Cattle farming is not to blame for the fires happening in the Amazon.

C．The problems the Amazon faces are more complex and can't be solved.

D．The Dinos are considered to be bad for burning the forest to make a fortune.

4. What should the Brazilian government do to solve the Amazon problems？

A．Prevent the deeds of burning.	B．Offer more land.
C．Take stricter measures.	D．Appoint economic models.

9 . My nephew came for a visit one hot,July weekend. I persuaded him to stay inside by joining him in a Nintendo game. After being mercilessly defeated by a more experienced player,I suggested that we relax for a while. He slipped out of the room and I caught a few moments of peace and quiet.

"Look,Alice," he said enthusiastically as he ran over to the chair where I was recovering." I found a kite. Could we go outside and fly it?"

Glancing out of a nearby window,I noticed there was not a breeze(微风). "T' m sorry, Tripper," I said, sad to see his disappointed eyes, but thankful for the short period of rest from more activities. "The wind is not blowing today.The kite won't fly."

The determined 10-year-old replied. "I think it's windy enough.I can get it to fly," he answered,as he hurried out through the back door.I peeked(窥视)through the curtains to watch determination in action.Up and down the yard he ran, pulling the kite attached to a small length of string.The plastic kite, proudly displaying a picture of Batman, remained about shoulder level. He ran back and forth, as hard as his ten-year-old legs would carry him, looking back hopefully at the kite trailing behind. After about ten minutes of unsuccessful determination, he came back in.

I asked, "How did it go?" "Fine, "he said," I got it to fly some." As he walked past me to return the kite to the closet shelf, I heard him say under his breath, "I guess I'll have to wait for the wind.”

At that moment I heard another voice speak to my heart. "Alice, sometimes you are just like that. You want to do it your way instead of waiting for the wind." And the voice was right. We usually want to use our own efforts to accomplish what we want to do. We wait for the wind only after we have done all we can and have exhausted our own strength. We must learn how to rely on Him in the first place!

1. Why did the writer refuse to fly the kite with his nephew that day?

A．Because he preferred to relax himself.

B．Because he was not good at flying kites.

C．Because he wanted to stay peaceful and quiet.

D．Because he found the weather was not suitable.

2. What can we infer from Paragraph 5?

A．Tripper was unwilling to admit defeat.

B．Tripper felt unhappy and hopeless.

C．Tripper was hesitant to try it again.

D．Tripper lost interest in flying the kite.

3. Which words can best describe Tripper?

A．Naughty and active.

B．Determined and insistent.

C．Brave and bright.

D．Weak and sensitive.

4. What is the best title for the text?

A．Fly a Kite in Life

B．Try Your Best

C．Wait for the Wind

D．Determine to Succeed

10 . I was driving down the road the other day, listening to sweet music coming out of my car radio. My heart felt peaceful, my mind was clear, and my soul was full of love. Even with all its problems: life seemed good. Then the music stopped and the news came on. There was talk of another famous millionaire in drug rehab (康复) after an incident with the police. There was news on the murder of a poor man whose life was supposed to be changed after winning the lottery. There was even a discussion on how much greed and excess (放肆) had damaged our world.

Every story seemed to point once again to the old saying that money can't buy happiness. Hearing them made me think of a movie I saw many years ago on Mother Teresa's home for the dying in India. What struck me most when I watched it wasn't the unbearable poverty there. It wasn't the sickness and suffering that the people there were going through. It was rather the peaceful smiles of love, kindness, and happiness that they shared with the Sisters and with each other. These people had nothing. Many were struggling at the end of death. Yet, they knew the simple truth that so many of us here are still learning: Joy is Free.

We can have joy and spread joy every day of our life here. Don't love or admire dollar signs and think that money will bring you happiness then. Joy can't be purchased. It can't be owned. It can only be chosen and then given freely to others. In the eyes of eternity (永恒), money is only worthless paper. The only thing that matters is the love within you and the love that you give to the world. Make that your legacy (遗产) and your life will forever be rich in joy.

1. According to the first paragraph, we can know that______.

A．the author was very lighthearted that day

B．the poor man's life was improved greatly due to the lottery

C．the author has a habit of driving while listening to music

D．the millionaire was put in prison for taking drugs

A．it was about Mother Teresa's contributions

B．it left the author a deep impression

C．people in it were very kind and happy

D．people in it were extremely poor and suffering

3. By saying "Make that your legacy", the author means "______".

A．Give your fortune to your coming generations

B．Treat your fortune as very valuable things

C．Pass your joy on to your coming generations

D．Have joy and spread joy to people around you

4. Which section of a newspaper is this passage most probably taken from?

A．Business.	B．Culture.
C．Life.	D．Entertainment.
