   A recent study shows that gossip(流言蜚语)is more powerful than truth.It suggests people believe what they hear through the grapevine(小道消息)__36__they have evidence to the contrary.

   Researchers, __37__students using a computer game, also found gossip played an important role when people __38__ decisions."We show that gossip has a strong __39__, even when people have __40__ to the original information as well as gossip about the same information.Thus, it is __41__ that gossip has a strong controlling potential," said Ralf Sommerfeld, who led the study.

   In the study, the researchers __42__ the students money and allowed them to give it to others in a series of rounds.The students also wrote __43__ about how others played the game that everyone could review.Students tended to give __44__ money to people described as “scrooges (吝啬鬼)” and more to those described as “__45__ players”.“People only believed the gossip, not the past decisions," Sommerfeld said in a telephone interview.

   The researchers then took the game a step_46_and showed the students the actual decisions people had made.But they also supplied false gossip that contradicted that __47_.In these cases, the students_48_ their decisions to award money on the gossip, __49__ the hard evidence.

   “If you know what the people did, you should care, but they still __50__ what others said,” Sommerfeld said.Researchers have __51__ used similar games to study how people cooperate and the __52__ of gossip in groups.Scientists define gossip __53__ social information spread about a person who is not __54__.In evolutionary terms, gossip can be an important tool for people to __55__ information about others' reputations or find the way through social networks at work and in their everyday lives.

    Though “nanometer”(纳米) 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(粒子)or crystallites(晶体) 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.

A water molecule(分子) is composed of 2 hydrogen atoms and 1 oxygen atom.It can be changed only by special manipulation of the atoms. The material constituting the cup can have ananometer particles . 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.

Professor Ji who worked in the Instiute of Nanomedicine told the reporter, so far, the investigation of nano materials is still limited in the laboratory. No commercial micro products can be produced yet. With the present level of science and technology, the time of everyday goods made of nanometer materials is still years away.

The products 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(耐磨), much easier to be cleaned, or oil resisting or moth proof(防蛀).

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

72.Which of the following shows the right relationship?

       A.nanometer<millimeter<micrometer<meter

       B.micrometer<millimeter<nanometer<meter

       C.nanometer<micrometer<millimeter<meter

       D.millimeter<micrometer<nanometer<meter

73.It can be inferred from the passage that       .

       A.nano materials have been put into use in daily goods

       B.real nano products haven’t become available for people

       C.the nano cup is very effective in curing and health care

       D.real nano products are being produced by some companies

74.The underlined word “properties” in the fourth paragraph probably means        .

       A.possessions      B.qualities    C.reactions   D.symbols

75.What would be the best title for the passage?

       A.High-tech Products  B.Nano Cups

       C.Nano Materials        D.High-teach Research
