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

Fashion, a term that is related to clothes, accessories(配饰), hairstyles and so on, is like a wind and is changing rapidly. From school-aged kids to working adults, everybody wants to look best. Fashion is promoted mostly by TV advertisements and celebrities. Many people define their fashion statement as comfort. They wear whatever they feel comfortable. 1.You can't wear a jogging suit to attend a wedding, and similarly you won't wear a dress to jog.
Nowadays, fashion has become one common language for people all over the world. It helps to connect people internationally, because it travels from one city to another. Sometimes, fashion can be an inspiration for many to discover their hidden potential. 2.In other words, fashion inspires some people to extend their knowledge and creativity to turn their hobby into a career. And therefore, fashion offers employment opportunities to those who dream of being part of the fashion industry.
Besides, following your own fashion statement makes you a more independent thinker. If you think you have the ability to wear fashion clothes, then it gives you a great deal of confidence. It also helps you make new friends easily. If you share the same interest with other people, then communicating with them won't be difficult. 3.

Those who are concerned that robots are taking over the world can rest easy—for now. Though the androids have proved useful at performing ordinary tasks, they are not ready for the greatest time. At least that appears to be the case at Japan’s Henn-na Hotel chain where over half of the robot staff are being replaced by humans.
The first location of the unique hotel opened in July 2015 was at Nagasaki’s Huis Ten Bosch Theme Park. The hotel’s owner, Hideo Sawada, promised the hotel to be managed primarily by robots. Guests were greeted and checked-in by a dinosaur robot, while a cute android called Churi, placed inside each room, provided information about attractions. Not surprisingly, the lodging, recognized in 2016 as the world’s first robot-staffed hotel by Guinness World Records, drew in curious visitors from all around the world.
But as the years have passed, the hotel’s main draw is becoming less novel and more unsatisfactory. Also as the robots are “aging”, they are costing more to repair. Among the 283 androids being replaced are the chain’s two dinosaur receptionists. In addition to scaring young guests, they are also unable to photocopy guests’ passports, forcing human employees to step in each time. Also out are the cute Churi robots, which annoyed guests by interrupting their conversations. For example, one guest told The Wall Street Journal that Churi mistook his snoring for a command and kept asking him to repeat his request all night.
Sawada told The Wall Street Journal, “When you actually use robots you realize there are places where they aren’t needed—or just annoy people.” While Sawada may be cutting back on his use of androids, the recently-opened Smart LYZ Hotel and the Fly Zoo Hotel in China, are run entirely by robots, with not a human in sight. Whether the employees have more competence than those “hired” by the Henn-na Hotel chain remains to be seen.
1.What makes Japan’s Henn-na Hotel unique?
A.Its robot employees. B.Its advanced equipment.
C.Its convenient location. D.Its successful management.
2.What is the author’s purpose with the example in paragraph 3?
A.To entertain readers. B.To prove Churi’s drawback.
C.To introduce Churi’s functions. D.To persuade people not to book the hotel.
3.What does the owner of Japan’s Henn-na Hotel think of his robot staff now?
A.Attractive. B.Costly.
C.Pioneering. D.Disappointing.
4.What is the best title for the text?
A.Robots Are Taking Over the World.
B.The Boom of Robots-staffed Hotel.
C.Robot Staff Are Fired For No Competence.
D.The First Robots-staffed Hotel Won Guinness World Record.
