  Some animals and insects(昆虫)use camouflage that is, they change color so that it is the same as the color of the tree or plant on which they are sitting. Others have developed a color thousands of years which is like the color of their living place.

  One of the second kind is the Peppered Moth, which is found in England. It is light brown in color, and likes to rest on trees which are also light brown. This makes the moth difficult to be seen. It means that birds are less likely to see it and eat it.

  But, about sixty years ago, smoke from factories began to reach some of the trees where the moth rested. It made the trees blacker. This meant that the moth become easier to see.

       ●Greenwich Park is a beautiful large park located a few kilometers away from the centre of London. Attractions in Greenwich include the Cutty Sark, the Gypsy Moth and the Old Royal Observatory. A painted line at the observatory indicates zero degrees of longitude(经度).

       Many visitors to Greenwich enjoy having their photos taken with one leg in the western hemisphere(半球)and the other in the eastern hemisphere. Greenwich is the place where time was officially tracked – “Greenwich Mean Time” or “GMT”.

       Greenwich is located in London SE10.

       ●The Eurostar high – speed train service provides fast connections between London and Paris and London and Brussels. The Eurostar trains pass through the 32 – mile Channel Tunnel under the English Channel. The tunnel is also known as the “Euro Tunnel” or “Chunnel”. The Channel Tunnel is considered to be one of the world’s great engineering wonders.

       Trains leave form the Waterloo Rail Station which is located in south London.

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
