Though “nanometer” is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.

Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?

Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation  of the application of nano technology into medicine.

Ji(director Institute of Nanomedicine):

A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body.

Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away.

The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them more abrasion resistant,much easier to be cleaned,or oil repelling or moth proof.

Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not changed its property and function as a cup.It is not a magical medicine for curing and health care.

Which of the following shows the right relationship?

A.nanometer<millimeter<micrometer<meter

B.nanometer<micrometer<millimeter<meter

C.micrometer<millimeter<nanometer<meter

D.millimeter<micrometer<nanometer<meter

The underlined part in the last second paragraph but one is about_________.

A.the strong points of nano cups                        B.the shortcomings of nano cups

C.the uses of nano cups                                     D.the wonders of nano cups

C.Nano cups are much easier to be cleaned.

D.Nano cups are hard to produce.

When you take a taxi in the United States, if you sit in the front seat, the driver will be pleased and talk with you all the way. If you sit in the back seat, however, the driver may be unhappy and unwilling to speak.
At first, I thought that this had something to do with different characters (性格) of the drivers. Later, after I’d had more experiences with taxis, I found that it happened very often. Only when I arrived in San Francisco did I ____________.
I went to see Sonia in San Francisco. One day, Sonia drove the car while her husband, Ji An, sat beside her, and I sat behind Ji An. Later, Ji An got out of the car and suggested that I sit where he had been sitting. It’s not a long way, so I told him that it didn’t matter, but Ji An insisted. I had to move, feeling a little strange.
“Do you know why Ji An asked you to sit here?” Sonia asked me. I shook my head. “If you sit in the front, it means that you and I are friends. If you sit in the back, it seems that I’m just your driver and our relationship is of employer and employee.”
With those words, I understood at once why taxi drivers were so pleased when people sat in the front. On the face of it, the only issue was where one sat. As a matter of fact, where to sit also reflected (反映) the degree of one’s respect for the driver.
Although it is true that the relationship between driver and passenger is a business relationship, people still place an emphasis (强调) on respect and friendship beyond any monetary (金钱的) relationship.
