               Microwaves may be great at warming up food, but what about warming people?
              Using microwaves to directly heat owners of a room would save much of the energy wasted by
           heating walls and furniture. And despite popular ideas about microwaves, this technique would be
           safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New 
          Hampshire. Low-power microwaves only penetrate (貫穿) the skin (low-power microwave
           penetration in a ham is about 0.2 inches, for example) and with no negative effects.
              To test this idea, Buffler subjected himself to microwaves in a special room using a standard 
          500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at
           about 20 milliwatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs
           between 35 and 50mw. / sq. cm. By comparison, a person standing in noonday summer sun feels 
          the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000
           mw. / sq. cm.
              In houses of the future, each room could be provided with its own magnetron, says Buffler. When 
          you stepped into the living room, for example, a motion detector (運動感應(yīng)器)would turn on the 
          magnetron, filling the room with low-power microwaves. In the same way that a microwave oven
           heats up a hamburger, but not the plate it's on, you would feel warmth from the microwaves without
           changing the temperature of your coffee table. (You could, however, make your favorite easy chair 
          even more comfortable by treating it with a radiation-absorbing chemical.)
              While it might be some time before homeowners are comfortable enough with the idea to set up
           whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜)
           farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves 
          could warm the lambs safely and quickly.
          1. Which of the following can tell the main idea of the passage?
          A. A new heating system.       
          B. A new microwave oven.
          C. A popular technique.        
          D. The magnetron.
          2. According to Paragraph 2, which of the following does not describe the characteristics of 
              a microwave heater?
          A. It directly heats people in a room.     
          B. It heats walls and furniture in a room.
          C. It is safe.                         
          D. It saves energy．
          3. The test conducted by Buffler shows that when a person feels comfortable warmth, 
              he receives about __________.
          A. 20 mw. / sq. cm.   
          B. 40 mw. / sq. cm.
          C. 60 mw. / sq. cm.   
          D. 85 mw. / sq. cm.
          4. According to Paragraph 4, which of the following fills the room with low-power microwaves?
          A. The magnetron.            
          B. The motion detector.
          C. The microwave oven.      
          D. The radiation-absorbing chemical.
          5. Which of the following statements about microwave heaters would Buffler most probably agree with?
          A. Microwave heaters will soon be widely used by homeowners.
          B. Microwave heaters sometimes make people feel uncomfortable.
          C. Perhaps microwave heaters will be first used by livestock farmers, who wish to 
               protect their lambs in winter.
          D. Microwave heaters cannot be accepted by the public because they are somewhat unsafe.

          　　You Mi, a lovely and confident 17-year-old student, is the first Chinese high school student to appear on the cover of the popular young adults’ fashion magazine Seventeen．
          

          　　“You is IN，” said Wang Lihua, Editor-in-Chief of Seventeen．“You is active and mature(成熟的)because of her knowledge on everything from academic studies，to books on art, to movies．We found she’s the very style we’re looking for to represent young people’s attitudes．”
          

          　　You also impressed Wang with her fluent English when they first met last year．As the hostess of an English broadcasting programme at the High School Affiliated to Renmin University，she is always praised for speaking English almost like a native speaker．“I’ve built up my English by watching thousands of English DVDs since I was 10,” she explained．
          

          　　But for her, watching isn’t enough．Last year，while in Senior 1, You met a talented boy who showed self-made DV movies at the English Corner in her school．
          

          　　“I thought it was so cool and I knew that I should start making my own films，” she said．So she wrote a campus(校園)story, persuaded schoolmates to star in it and then began shooting a 30-minute DV movie, all in English．“I played one of the leading roles, actually I was everything in my film．I worked on it every single day during the SARS holidays,” she recalled．The movie finally became a big hit on campus，earning You a strong reputation(名氣)as a DV movie director．
          

          　　But this is not the only field she wants to master．Despite being a science student, she likes art, literature and fashion design very much．
          

          　　“There are people who can be artists, there are people who edit books，and there are people who become film producers．But I just hope to mix all the things up!” she said．“There is an old saying I believe：Chance favours only the prepared mind．”

           Before I started school, people felt that 1 was not going to be successful．At the age of four I started speech lessons because basically I could not speak well enough for anyone to understand me．The story goes downhill from here．
           The first grade was a struggle．I not only had difficulty speaking, but also felt nervous about the fact that I was expected to learn to read and I just couldn't do it．The second grade was not much better．I still struggled with the inability to read．It was in the third grade that the school district built a new school close to my home．I remember going there with my parents and helping to get the school ready so that we could move to the new one．However, things were still not much better as far as my schooling was concerned and did not get better for the next two years．
           It was in the fifth grade．Mi-s．Wakefield was my teacher, and if ever there was a teacher that deserved a gold star, it was her．She did not make me feel defeated．On the contrary, she did her best to let me know that I could be whatever I wanted to be．And that is just what I did．
           For the past 22 years, I have been a fifth grade teacher．Because of Mrs．Wakefield's influence on my life, I am now encouraging students who have had difficulties in their lives to believe that they can overcome any difficulty and become someone．I have won numerous awards up to now, such as Teacher of the Year．I owe it all to one fifth grade teacher who believed in me and challenged me to be all that I could be．

                 閱讀下列短文，從每題所給的A、B、C、D四個選項中，選出最佳選項，并在答題卡上將該項涂黑。
            
                 Before I started school, people felt that 1 was not going to be successful．At the age of four I started speech lessons because basically I could not speak well enough for anyone to understand me．The story goes downhill from here．
            
                 The first grade was a struggle．I not only had difficulty speaking, but also felt nervous about the fact that I was expected to learn to read and I just couldn't do it．The second grade was not much better．I still struggled with the inability to read．It was in the third grade that the school district built a new school close to my home．I remember going there with my parents and helping to get the school ready so that we could move to the new one．However, things were still not much better as far as my schooling was concerned and did not get better for the next two years．
            
                 It was in the fifth grade．Mi-s．Wakefield was my teacher, and if ever there was a teacher that deserved a gold star, it was her．She did not make me feel defeated．On the contrary, she did her best to let me know that I could be whatever I wanted to be．And that is just what I did．
            
                 For the past 22 years, I have been a fifth grade teacher．Because of Mrs．Wakefield's influence on my life, I am now encouraging students who have had difficulties in their lives to believe that they can overcome any difficulty and become someone．I have won numerous awards up to now, such as Teacher of the Year．I owe it all to one fifth grade teacher who believed in me and challenged me to be all that I could be．
