          Even plants can run a fever, especially when they're under attack by insects or disease. But unlike
    human, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago,
    adopting the infrared(红外线)scanning technology developed for military purposes and other satellites,
    physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which
    ones are under stress. The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than
    rain poison on a whole field, which invariably includes plants that don't have pest problems.
         Even better, Paley's Remote Scanning Services Company could detect crop problems before they
    became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured
    the heat emitted by crops. The data were transformed into a colourcoded map showing where plants
    were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they
    otherwise would.
          The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted
    the new technology and longterm backers were hard to find. But with the renewed concern about
    pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation.
    Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of
    agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade.  But only if Paley finds the financial backing which he failed to obtain 10 years ago.

    1. Plants will send out an increased amount of heat when they are________.
    A. facing an infrared scanner
    B. sprayed with pesticides
    C. in poor physical condition
    D. exposed to excessive sun rays

    2. In order to apply pesticide spraying precisely, we can use infrared scanning to________.
    A. estimate the damage to the crops
    B. draw a colourcoded map
    C. measure the size of the affected area
    D. locate the problem area

    3. Farmers can save a considerable amount of pesticide by________.
    A. resorting to spotspraying
    B. transforming poisoned rain
    C. consulting infrared scanning experts
    D. detecting crop problems at an early stage

    　　Halloween is a festival (节日) celebrated on October 31st. The name of the holiday means“hallowed”or“holy evening”because it happens the day before All Saints Day (万圣节) . It is said that Halloween is the children's New Year's Eve. They dress up with special costumes(服装), they eat too much, and stay up too late celebrating.

    　　Children go around the neighborhood wearing make-up, and dress in masks(面具) and colorful costumes. The most common costumes are witches, ghosts, skeletons (骷髅) , and popular TV, movie, and storybook characters. Some costumes are homemade; others are bought in stores. The children go from door to door saying“trick or treat”. People give them candy, cookies, fruit or money. Sometimes money is collected to help UNICEF, United Nations International Children's Emergency Fund.

    　　Homes, stores, and classrooms are decorated (装饰) in the traditional Halloween colours, orange and black. Usual decorations are witches, ghosts, skeletons, and jack-o-lanterns. Jack-o-lanterns are pumpkins (南瓜) that are carved (雕刻) to look like faces. They are placed on doorway entrances and in windows. Horror movies and ghost stories are shown on TV on this day.

    　　Adults and older children also celebrate Halloween with parades (游行), festivals, and costume parties. Some people create their costumes; other people rent them. Contests are held, where the best costume receives a prize. One of the party events popular with children is dunking (浸泡) for apples. Apples are put in tubs filled with water.

    阅读下列短文，从每题所给的四个选项（A、B、C 和D）中，选出最佳选项。
    Having divorced (离婚) my dad, my mom had to move frequently in order to find a job that would provide her with enough money to support the big family. For three years, we lived in the town of Parkersburg. On the first Christmas there, my brothers and I had been well prepared for a holiday without presents. But we had a surprise on Christmas Eve.
    At midnight, we were woken up by someone shouting at our front door, “Ho, ho, ho! Merry Christmas!” We jumped up and ran to the door to find no one there, but several boxes and bags! Not only were there gifts, which were our favorite, but there were also clothes and food. Each of us kids, as well as Mom, had gifts with our names on them. And the clothes all fit us!
    Another year went by and on Christmas Eve, we again got boxes and bags full of goodies. The next year we moved. We were in the same town but across the other side. Mom was beginning to get on her feet. Since we had moved and Mom had a better job, we were quite certain that “Santa” wouldn’t visit us that year. But we were wrong!
    Those “Santa” visits restored in me the belief in the goodness of mankind, though to this day we don’t know who our helper was.
    When we grew up, Mom moved to Virginia. She had some extra money one Christmas. She sent it to me and let us know her decision. We then took action. My husband and children had so much fun buying and wrapping presents for the needy family we had chosen. On Christmas Eve, we allowed the excited kids to stay up late to be part of our secret “Santa” project.
    Such satisfaction there was in being able to pass on the gift of love to others who needed it. And the gift goes on!

    On Christmas morning，we were excited for Almie to open the little heart-shaped package with the beautiful red and white clay bike and the note．Finally，she opened it and read the note aloud．“Does this mean that I trade in this bike that Daddy made me for a real one?”Beaming，I said，“Yes．”Almie had tears in her eyes when she replied．“I could never trade in this beautiful bicycle that Daddy made me．I’d rather keep this than get a real bike．”At that moment，we would have moved heaven and earth to buy her every bicycle on the planet!

    第三部分：阅读理解(共20小题；每小题2分，满分40分)

       When my first wartime Christmas came, I was in basic training in New Jersey and not sure if I could make it home for the holidays. Only on the afternoon of December 23 was the list of men who would have three-day passes posted. I was one of the lucky soldiers. It was Christmas Eve when I arrived home, and a light snow had fallen. Mother opened the front door. I could see beyond her, into the corner of the living room where the tree had always stood. There were lights, all colors, and ornaments shining against the green of a pine. "Where did it come from?" I asked.

        "I asked the Gates boy to cut it," my mother said. "I wouldn't have had one just for myself, but-such a rush! He just brought it in this afternoon…" The pine reached to the proper height, almost to the ceiling, and the Tree Top Krystal Star was its place. A few green branches reached about a little awkwardly at the side, I thought, and there was a bit of bare trunk showing in the middle. But the, tree filled the room with warm light and the whole house with the pleasant smell of Christmas.  "It's not like the one you used to find." my mother went on. "Yours were always in good shape. I suppose the Gates boy didn't know where to look. But I couldn't be fussy(挑剔的)."

        "Don't worry," I told her. "It's perfect." It wasn't, of course, but at the moment I realized something for the first time: all Christmas trees are perfect.

    3. "All Christmas trees are perfect", because they can remind you of        .

       A. the wartime                    B. the green of a pine

       C. the pleasant moment             D. the sweet home

    4. The best title for this passage would be "        ".
