Then he said, “Excuse me too... I wasn't 36 watching for you.” We were very polite, this stranger and I. Then we went 37 our way after saying goodbye.‎ ‎ But at 38 , a different story is told. How we treat our loved ones, young and old. Later in the kitchen, as I 39 our meal, my daughter walked up to me, very still. When I turned, I 40 knocked her down. “Get out of the way!” I shouted with a frown(皱眉). She stepped away silently, with her little heart 41 . I didn't realize how harshly(苛刻地) I had spoken.‎ That night, when I lay ‎42 in bed, God's quiet voice spoke to me and said, “While 43 with a stranger, you are calm and polite, but with those you love, you are QUICK to excite... Go look around on the kitchen floor, you'll find some flowers there by the 44 . Those are the flowers she brought for you. She 45 them herself-- pink, yellow, and your favorite blue.

A normal course load is four or five courses per term, although many students take extra courses.‎ Residences ‎ ‎ Princeton provides housing for all undergraduate students. Freshmen and second-year students are required to spend their first two years in one of five colleges. Each college has its own dining hall, common rooms and computer centers.‎ Fees and Expenses (Academic Year 2011-2012) ‎ Tuition (学费): $29,910 ‎ Room and board: $ 8,387 ‎ Other expenses (books, telephone, etc．): $ 3,083 ‎ Total: $ 41,380 ‎ ‎56．How many kinds of faculty members are there in Princeton‎ ‎University?‎ A．One B．Two C．Three D．Four ‎57．In what way is Princeton‎ ‎University different from other American universities according to the text?‎ A．It has five colleges.‎ B．Its students are mainly undergraduates.‎ ‎ C．It provides housing for all undergraduate students.‎ D．All the faculty members at Princeton are expected to teach and research.‎ ‎58．Which of the following is NOT true?‎ ‎ A．Princeton offers two undergraduate degrees.‎ ‎ B．An academic year lasts about nine months in Princeton‎ ‎University.‎ ‎ C．Undergraduates should spend their first two years in one of five colleges.‎ ‎ D．It's about an hour's train ride from Princeton University to the north of New York City.‎ B ‎ The breaking news of Mo Yan's Nobel Prize in Literature on Thursday evening soon aroused public curiosity of the 57-year-old Chinese writer: Why was he favored by the Swedish‎ ‎Academy?‎ ‎ Less than half an hour after the announcement from Stockholm, Mo's works turned to “sold out" status at China's major online book sellers．‎ ‎ One lucky buyer wrote in an online comment: "Rushed to purchase, but to my shame, I have not read any of his novels．”‎ ‎ Although Mo was entitled one of the top China's literature awards before the Nobel Prize, he is not the most popular novelist in China, in either the book market or in reputation．‎ ‎ Chinese media seemed to be shocked as some journalists were reported to be on their way overnight to Gaomi City of East China's Shandong Province, Mo's birthplace where he stayed with his family．‎ ‎ Born in 1955 into a rural family, Mo dropped out of school and became a farmer when he was a teenager． He joined the army and devoted himself to writing． Mo's novels were translated into several languages．‎ ‎ For more than a century, Nobel Prize has been regarded by the world as recognition to an individual or even a nation's cultural and scientific advances．‎ ‎ “I think the reason why I could win the prize is that my works present lives with unique Chinese characteristics, and they also tell stones from a viewpoint of common human beings, which transcends（超越）differences of nations and races," Mo said on Thursday evening to Chinese journalists．‎ ‎ Mo also said many folk arts originated from his hometown, such as paper cuts and traditional new year paintings, have inspired and influenced his novels．‎ ‎ Mo's prize may give powerful encouragement to the country's writers as the more reflective of Chinese lives their works are, the more possible they arise as world literature．‎ ‎59．From this passage we know that the news of Mo Yan's Nobel Prize in Literature was .‎ ‎ A．a shock to online booksellers ‎ B．curiosity to the ‎Swedish‎ ‎Academy ‎ C．contrary to the belief of the Chinese media ‎ D．beyond the expectation of most Chinese people ‎60．The "one lucky buyer" mentioned in the third paragraph admitted that he _ ．‎ ‎ A． had not yet read Mo Yan's novels B． had written an online comment ‎ C． regretted not reading Mo Yan's Novels D． failed to buy a copy of Mo Yan's novels ‎61．The underlined word "they" in the last paragraph refers to .‎ ‎ A． the Chinese writers B．the Chinese writers' works ‎ C． the Chinese lives D．Mo Yan's novels ‎62． What can we infer from this passage?‎ ‎ A．Mo Yan will win another Nobel Prize in the near future．‎ ‎ B．Folk arts originated from Mo Yan's hometown will also be awarded Nobel Prize． ．‎ ‎ C．Nobel Prize will no longer regarded by the world as recognition to an individual．‎ ‎ D．Mo Yan's success will encourage the Chinese writers to win more Nobel Prizes．‎ C What can you do？Here are some suggestions：‎ Switch the channel when negative thoughts appear. Self-talk（自我暗示）is not so obvious that we often don′t notice its effect on our mood and belief systems. Key things to notice are “if only” or “what if” statements：the former keeps you stuck in the past with regret, while the latter keeps you fearful of the future. There is nothing you can do about the past, and the future isn′t here yet，so stay in the present moment.‎ Recognize that actions always follow beliefs．You′ll find yourself behaving in ways that are consistent to your beliefs．So，start believing the best about yourself：act as if you believe that you′re a valuable and worthy person．‎ Develop positive self-talk rather than negative self-talk．Instead of always looking down upon yourself in your head，think of some things you actually like about ‎ yourself．What are your strengths? What are you good at? Instead of saying “I′ m a loser”，try saying，“I am capable.／I′m good at…／I accept myself the way I am．”‎ Thinking poorly about ourselves gets us nowhere and is extremely self-limiting.

They talk to you, they take care of you, and they enrich you with wisdom, humor and love. A book is a guest in my home. How could I kick it out? I repaired torn pages.

These books have many advantages. One of them is that we can find a variety of topics, such as science, culture and history. These topics, I think, are very popular with us students. What’s more, along with the texts there are many beautiful and colorful pictures, which can help us understand English better. Even the students who used to dislike English have turned out to be interested in the subject. However, some of the texts have too many new words and expressions which are hard for us. Therefore, I’d like to suggest changing them into easier ones. ‎ Best regards,‎ Li Hua ‎ 一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一
