I lived in an orphanage(孤儿院）when I was 8. A gentleman came and taught us how to do woodworking projects.

I remember my first project ---a small table. I was so   41   of it that I looked upon it as if I had created a(n)   42  . It had taken me six weeks to   43  it. I could hardly wait to give it to Mother Winters as a   44  . She was the head mistress of our orphanage, who was always  45   with us.

As the tables were not dry, the man told us to wait a few days. But I was just so   46  and happy that I couldn’t wait. I dashed out like a   47  carrying my table.

When I was    48   it in the dormitory, Mother Winters entered. She walked over to the table. Running her hand    49  it, she noticed that it was still wet.

“Were you    50    to bring this home?” she asked.

“No, ma’ma,”I   51   with my head down.

She ordered me to throw the table out and so I did. After she left, I opened the door to get it back. There was   52   stuck all over. I brushed and cried.

I hid the table in my closet and never    53   it. After cleaning up, I gave the table to Mother Henderson, my houseparent(宿管员), thinking that she would   54   it away.

Thirty years later at a reunion, I   55   that Mother Henderson was living nearby, so I drove up to see her. As I was about to leave, she asked me to come down to her   56

to get something. I followed her   57   into a dark corner. She picked something up.   58   she turned around, I could see that she was holding a little table.

   Mother Henderson still kept the little table!

   Today, I look at that table with bitter-sweet memories but full of    59   to Mother Henderson, who kept it for an orphan who tried very hard to   60   himself.

I still clearly remember that day．I was on the side of the road for about four hours with my big jeep．I put signs in the windows that said, "Need a jack （千斤顶）．"

As I was about to give up, a truck stopped and a man got off．He looked at the situation, made a judgment and went back to take a jack．After about two hours, we finished the job with sweats．We were both dirty．His wife took a large bottle of water for us to wash our hands．

I tried to put $ 20 in the man's hand, but he wouldn't take it, so I went to give it to his wife as quietly as I could．I asked their little girl where they lived, thinking maybe I'd send them a gift．She said they lived in Mexico．They were in Oregon now, so Mommy and Daddy could pick cherries for the next few weeks．After that, they were going to pick peaches and then go back home．

After I said goodbye and started going back to my jeep, the girl ran to me and handed me a tamale（玉米粽子）for lunch．I thanked them again and walked back to my jeep．When I opened the tamale, what did I find inside? My $ 20! I ran to the truck and the guy rolled down his window．He started shaking his head, smiled, and with what looked like great concentration said in English, "Today you, tomorrow me." Then he drove away, with his daughter waving to me from the back．

This family, working on a seasonal basis where time is money, took a couple of hours to help a stranger while others passed by quietly．

Since then I've helped many people like the Mexican family．I didn't accept their money．Every time I was able to help, I felt as if I was putting something in the bank．

56．From the passage we can know that _______.

       A．the Mexican man couldn't speak English

       B．the author's jeep broke down on the road

       C．the Mexican family came to Oregon for a visit

       D．$ 20 was a small amount for the Mexican family

57．The author hand the money quietly to the man's wife because _______.

       A．the Mexican man had refused to accept it

       B．the Mexican man's wife needn't wash her hands

       C．the author thought the Mexican man's wife was a bit greedy

       D．the author thought the wife wanted to use the money to buy peaches

58．The Mexican man helped the author because he tended to think that _______.

       A．it was completely wrong for others to pass by quietly

       B．it was quite easy to help the author repair the jeep

       C．it was possible that everyone might get into trouble

       D．the author was a polite stranger and deserved the help

59．What can we infer from the passage?

       A．The Mexican family lived a richer life than the author．

       B．The Mexican family did seasonal work in Oregon in previous years．

       C．What made the author cry was the tamale given by the girl．

       D．The author was inspired to help others by the Mexican family．

   

Human Flesh Search—thousands of individuals working to find and make public someone’s personal information, mostly online—will be ruled as leaking personal data, which is against the law, according to China’s top court.

Internet users or network service providers who leak people’s personal information such as phone numbers, addresses, and clinical data will have to hold legal responsibility.

Network service providers will also be held responsible if they are aware that their users have violated others’ rights but have failed to take action.

The decision comes after years of arguments over whether it’s right for the public to try those who behave wrongly.

On the one hand, cyber hunting does have its positive influences. Some public officials have been removed from their positions after human flesh searches led to corruption investigations. During disasters like the Sichuan earthquake in 2008, the search method also helped many people to find their loved ones.

But many think that online cyber hunting is creating a threat to privacy. “People’s ‘unusually high enthusiasm’ makes the human flesh search engine phenomenon unique,” Xujun Eberlein, a Chinese American author and commentator, told Forbes. “Participants often ‘reach out their hands’ thoughtlessly, violating people’s rights instead of being righteous(正直).”

【写作内容】

1. 以约30个词概括短文大意；

2. 以约120个词就“Human Flesh Search（人肉搜索）”这一主题谈谈你的看法，内容包括：

1）你是否赞同文章提及的“禁止人肉搜索”的法案，请说明你的理由；

2）“网络时代，个人隐私如何才能得到保障？”请就此问题，提出你的建议（至少两点）。

【写作要求】

1. 可以参照阅读材料内容，但不得直接引用原文中的句子；

2. 作文中不能出现真实姓名和学校名称。

在国外不少地方垃圾桶上都用中文写着“请不要乱扔垃圾”，央视以此为背景特别制作了一则公益广告“中文应该被这样使用吗？”要做到中文不被这样使用，需要每个公民(　　)

C.将个人命运与国家前途结合起来           D.坚持法律面前一律平等的原则

下图是番茄植株进行光合作用的示意图，其中PSⅡ和PSⅠ是吸收、传递、转化光能的光系统。请回答下列问题：

（1） PSⅡ中的色素吸收光能后，将H₂O分解为H⁺和____。前者通过____的协助进行转运，促使ADP完成磷酸化;后者若进入同一细胞中被利用至少需要经过____层生物膜。

（2） 某研究者测得番茄植株在CK条件（适宜温度和适宜光照）和HH条件（亚高温高光）下，培养5天后的相关指标数据如下表。

组别	温度 /℃	光照强度/ （μmol·m-2·s-1）	净光合速率/ （μmol·m-2·s-1）	气孔导度/ （mmol·m-2·s-1）	胞间CO2 浓度/ppm	Rubisco活性 /（U·mL-1）
CK	25	500	12．1	114．2	308	189
HH	35	1000	1．8	31．2	448	61

注：两组实验，除温度和光照有差异外，其余条件相同且适宜。

由表中数据可以推知，HH条件下番茄净光合速率的下降并不是由于____导致光合作用缺乏原料CO₂造成的，而是由于____下降影响了②过程的速率，进而引起光能的转化效率降低。此条件下的光反应产物NADPH（）和ATP在叶绿体中的含量____（选填“增加”“降低”或“不变”），番茄所吸收的光能已经是过剩光能了。

（3） D1蛋白是PSⅡ复合物的组成部分，对维持PSⅡ的结构和功能起重要作用，且过剩的光能可使D₁蛋白失活。某研究者利用番茄植株进行了三组实验，①组的处理同（2）中的CK，②组的处理为____，③组用适量的SM（SM可抑制D₁蛋白的合成）处理番茄植株并在亚高温高光（HH）下培养，定期测定各组植株的净光合速率（Pn），实验结果如右图。根据实验结果分析，番茄缓解亚高温高光对光合作用抑制的机制是_______。

“My work is done.” Those words were some of the last penned by George Eastman. He included them in his suicide note. They mark an ignoble end to a noble life, the leave taking of a truly great man. The same words could now be said for the company he left behind. Actually, the Eastman Kodak Company is through. It has been mismanaged financially, technologically and competitively. For 20 years, its leaders have foolishly spent down the patrimony of a century’s prosperity. One of America’s bedrock brands is about to disappear, the Kodak moment has passed.

  But George Eastman is not how he died, and the Eastman Kodak Company is not how it is being killed. Though the ends be needless and premature, they must not be allowed to overshadow the greatness that came before. Few companies have done so much good for so many people, or defined and lifted so profoundly the spirit of a nation and perhaps the world. It is impossible to understand the 20th Century without recognizing the role of the Eastman Kodak Company.

  Kodak served mankind through entertainment, science, national defense and the stockpiling of family memories. Kodak took us to the top of Mount Suribachi and to the Sea of Tranquility. It introduced us to the merry old Land of Oz and to stars from Charlie Chaplin to John Wayne, and Elizabeth Taylor to Tom Hanks. It showed us the shot that killed President Kennedy, and his brother bleeding out on a kitchen floor, and a fallen Martin Luther King Jr. on the hard balcony of a Memphis motel.   When that sailor kissed the nurse, and when the spy planes saw missiles in Cuba, Kodak was the eyes of a nation. From the deck of the Missouri to the grandeur of Monument Valley, Kodak took us there. Virtually every significant image of the 20th Century is a gift to posterity（繁荣） from the Eastman Kodak Company.

  In an era of easy digital photography, when we can take a picture of anything at any time, we cannot imagine what life was like before George Eastman brought photography to people. Yes, there were photographers, and for ly large sums of money they would take stilted（不自然的） pictures in studios and formal settings. But most people couldn’t afford photographs, and so all they had to remember distant loved ones, or earlier times of their lives, was memory. Children could not know what their parents had looked like as young people, grandparents far away might never learn what their grandchildren looked like. Eastman Kodak allowed memory to move from the uncertainty of recollection, to the permanence of a photograph. But it wasn’t just people whose features were savable; it was events, the sacred and precious times that families cherish. The Kodak moment, was humanity’s moment.

  And it wasn’t just people whose features were savable; it was events, the precious times that families cherish. Kodak let the fleeting moments of birthdays and weddings, picnics and parties, be preserved and saved. It allowed for the creation of the most egalitarian art form. Lovers could take one another’s pictures, children were photographed walking out the door on the first day of school, the person releasing the shutter decided what was worth recording, and hundreds of millions of such decisions were made. And for centuries to come, those long dead will smile and dance and communicate to their unborn progeny（子孙）. Family history will be not only names on paper, but smiles on faces.

  The cash flow not just provided thousands of people with job, but also allowed the company’s founder to engage in some of the most generous charity in America’s history. Not just in Kodak’s home city of Rochester, New York, but in Tuskegee and London, and at the Massachusetts Institute of Technology. He bankrolled（资助） two historically black colleges, fixed the teeth of Europe’s poor, and quietly did good wherever he could. While doing good, Kodak did very well. Over all the years, all the Kodakers over all the years are essential parts of that monumental legacy. They prospered a great company, but they – with that company – blessed the world.

  That is what we should remember about the Eastman Kodak Company. Like its founder, we should remember how it lived, not how it died. History will forget the small men who have scuttled this company. But history will never forget Kodak.
