下面幾個人分別就父親對自己的影響表達了看法。閱讀下面所給的五個選項（A、B、C、D、E），選出符合各自看法的最佳選項。選項中有一項是多余選項。

1.Kitty: Dad encouraged me to keep great determination to do anything.

2.Kelly: Dad gave me a new life which is full of love and happiness.

3.Aidan: Dad is the person who introduced me to my sports career (生涯).

4.Bruce: Dad taught me to share housework and take family responsibility.

A．Dear Daddy, you stepped into my life years ago, and became my dad, a man who raised three fatherless kids and adopted (收養(yǎng)) another. You did everything for us, and you managed to have taken care of Mom, who has been sick, and the grandkids as well. Lessons learned are love, and kindness. We love you dearly.

B．My dad taught me how to play basketball. Now I am a professional player at basketball. Although I sometimes didn’t play well, my dad always encouraged me not to lose heart. Now I have a dream of being able to play basketball on the Celtics. I love my dad!

C．The most important thing that my dad ever taught me was “Never do anything halfway”. He always told me to do my best to show my ability and character. “It shows what kind of person you are,” my dad would say. “People will remember and respect you for that.”

D．My dad has taught me love, hope, respect and the value of hard work. He has taught me never to be afraid; he has taught me the value of a job well done; he has taught me how to ride a bike, then to drive a car. He always tells me that he believes in me and that I can manage to deal with the things around me.

E. My dad and I have a funny company called “Priority”. He has taught me how to take care of the pool (Priority Pool), how to plan family birthday parties (Priority Parties), and how to clean the computer (Priority Computers). The list goes on. I’m proud of my dad and grateful for my time with him. We have a lot of fun doing daily housework together.

 —Ouch! You hurt me!

—I am sorry. But I   any harm. I      to drive a rat out.

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 kilowatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and 50 mw. / 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.

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.
