  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. Buffler of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) 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 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 would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwaves 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 farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.

“What’s in a name?”According to Shakespeare’s Romeo and Juliet,there is not too much.“That which we call a rose by any other name would smell as sweet.”But Shakespeare may have been wrong.In most cultures,names matter a great deal.
Americans choose names for their children with care.Parents usually think about the impression a name gives,not its meaning.Most Americans would consider a“Jennifer”more attractive than a “Bertha”，for example.The last name,or,surname,must also be considered when choosing a first and middle name.A name like Lester Chester Hester would sound poetic,but odd.Parents would avoid names that remind them of people they don’t like.On the other hand,people might name their children after a respected elderly relative or even a famous person.The popularity of certain names can change with each new generation.Names that were once common,like Fanny or Elmer,sound old-fashioned today.But other names—like John and David,Mary and Sarah—have stood the test of time and continue to be favorites.
People in Ameica don’t always call their friends and relatives by their given names.Instead,they often use nicknames.Sometimes nicknames are short forms of a longer name.For instance,a girl named Elizabeth may be called Lisa,Beth or Betsy.As children grow up,they may decide for themselves which nickname they wish to be called.Some people just go by the initials of their first and middle names,like B.J.or R.C.And of course,people may call their children or their sweethearts other special nicknames.Often they have a “sweet” flavor,like Honey or Sugar.What’s in a name? A world of significance.So if you’re choosing an English name for yourself,take care to choose a good one.Amade-up name could sound strange to native English speakers.And a translation of your Chinese name may not make an appropriate name,either.But a good name can leave a positive and lasting impression.As an American politician once said,“In real life,unlike in Shakespeare,the sweetness of the rose depends upon the name it bears.”
1.What does the underlined sentence in paragraph 2 mean?
A.People change names in order to be popular with the new generation.
B.Names will change by themselves in order to be popular.
C.Some names may no longer be popular among the new generation.

A.the impression a name gives is more important than its meaning
B.you can name after a well-known person
C.surname should be paid attention to
D.you can create a name that is special

A.nickname            B.the first letter        C.short form        D.title
4.The author will name a newly born baby girl             .
A.Bertha               B.Fanny             C.Yunyun          D.Elizabeth
5.What is the main idea of this passage?
A.Names have great significance to Americans.    
B.Names change when time goes by.
C.Chinese people should be careful when choosing their English names.
D.Roses smell sweet by any other name.

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 (贯穿) 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 (运动感应器)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.
