题型：不详难度：来源：
The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin (弹性树脂) that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris (石头碎片) or even on-purpose destruction.
The automaker admits its results vary depending on the temperature and the depth of the damage, but adds this is the only paint like it in the world, and tests prove it works.
Minor scratches, the most common type, are said to slowly fade over about a week. And once they’re gone, there is no trace that they were ever there.
The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period.
Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents.
But the complete auto-healing won’t come without scratching your wallet. The vehicle maker notes the special paint adds about $100 US to the price of a car.
It plans to use its new chemical mixture only on its X-Trail SUVs in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven’t been made yet, if it’s a hit there, you can be almost sure market forces will drive it to these shores, as well.
小题1:From the article, we can find that _________.
| A．the paint has already been used on cars by now |
| B．it beats other products of its kind in its lengthy effect |
| C．car damage is mainly caused by scratches and scrapes |
| D．marketing this paint in Europe is not under way |
| A．last 3 years before it is reapplied again |
| B．fade only in a few days |
| C．help to protect minor paint damage |
| D．reduce car scrape incidents to 20 percent |
| A．certain models of Nissan | B．name for one kind of paint |
| C．somewhere in Japan | D．a word standing for a car-dealer store |
| A．The paint was developed by Nissan Motor Company. |
| B．The paint might work better in summer than in winter. |
| C．The mark on the car could disappear as soon as the pain is applied. |
| D．The paint is very popular in Japan. |
答案
小题1:D
小题2:C
小题3:A
小题4:B
解析
小题1:从最后一段第二句“And while plans to offer the feature overseas haven’t been made yet, …”可知，D项是正确的。根据第一段和最后一段可排除A项。由第三段的this is the only paint like it in the world可知，它还没有同类产品，所以可否定B项。选项C在文中没有作出说明。
小题2:从文中第四段可找到答案。文中第五段说这种漆经过三年后是否还可以上漆并没有说明，所以A项被排除。B选项叙述错误，不是漆消退，而应是刮痕消退。D项在文中没有被提到。
小题3:第一段提到日本的Nissan汽车公司宣布下一个项目就是使用这种漆，所以最后这一段应是计划把这种漆用在这个公司的某款汽车上，即A项是正确的。
小题4:由第二段的第一句话可推断出B项是正确的。由第二段的第一句可知A项错误。由第一段的最后一句和第四段的第一句可知刮痕并不是马上消失的，所以C项错误。从最后一段as it looks for a more widespread presentation可知，这种漆并没有推广开，所以D项错误。
核心考点
试题【After years of hearing drivers complain about scratches on their cars, Japan’s N】；主要考察你对题材分类等知识点的理解。[详细]
举一反三
1.What do you do with it?
Go to a telephone box marked “Phonecard”.Put in your card,make your call and when you"ve finished,a screen tells you how much is left on your card.It costs no extra for the cards,and the calls cast 10 per unit,the same as any other payphone call.You can put them in units of 10,20,40,100 or 200.
2.Now appearing in a shop near you
Near each card phone place you"ll find a shop where you can buy one.They"re at bus,train and city tube stations.Many universities,hospitals and clubs,restaurants and gas stations on the highway and shopping centers.At airports and seaports.
3.No more broken payphones
Most broken payphones are like that they"ve been vandalized（破坏了的）.There are no coins in Cardphone to excite thieves" interest in it.So you"re not probably to find a vandalized one.Get a phonecard yourself and try it out.Or get a bigger wallet.
小题1:There are three sections in the passage.Which section do you think is about why phonecards are good?
| A．Section 1. | B．Section 2. | C．Section 3. | D．Section 1&2. |
a.Put in your phonecard.
b.Look at the screen to find out how many calls you can still make.
c.Go to a telephone box marked “Phonecard”.
d.Make your call.
| A．a,b,c,d | B．c,a,d,b | C．a,d,c,b | D．c,d,a,b |
| A．Phonecards are cheap |
| B．You cannot use all payphones |
| C．Thieves will not break card phones |
| D．People do not like carrying a lot of coins |
When cold weather comes,many birds move to warmer places to find food.Some fishes give birth in warm water and move to cold water to feed.The most famous migration（迁移）is probably the migration of fish,which is called “Salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life.When it is old,it returns to its birthplace in fresh water.Then it gives birth and dies there.In northern Europe,there is a kind of mouse.They leave their mountain homes when they become too crowded.They move down to the low land.Sometimes they move all the way to the seaside,and many of them are killed when they fall into the sea.
Recently,scientists have studied the migration of a kind of lobster（龙虾）.Every year,when the season of bad weather arrives,the lobsters get into a long time and start to walk across the floor of the ocean.Nobody knows why they do this,and nobody knows where they go.
So,sometimes we know why humans and animals move from one place to another,but at other times we don’t.Maybe living things just like to travel.
小题1:Most animals move from one place to another at a certain time to _________.
| A．give birth | B．enjoy warmer water |
| C．find food more easily | D．find beautiful places |
| A．they give birth | B．the weather is bad |
| C．the place gets too crowded | D．they haven’t enough food |
| A．to the fresh water | B．to the deeper sea |
| C．at a certain time | D．to find more food |
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.
小题1: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 |
| 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 |
| A．Nano cups can’t make people healthier. |
| B．Nano cups are made of a different material. |
| C．Nano cups are much easier to be cleaned. |
| D．Nano cups are hard to produce. |
| A．only traditional products |
| B．ordinary cups covered with a little nanometer material on the surface |
| C．cups made of a nano material |
| D．cups made of a mixed material |
A heavy snow can kill pests and this means a good harvest next year.This will bring as well as trouble to urbanites.
On Nov.16,2003,a cold air current brought a heavy snow to Beijing.To prevent traffic jams,related government departments mobilized people to clear off snow on streets.
One of the most effective ways to clear off snow on roads is to scatter snow-melting agent on the roads.The major component of the snow-melting agent is salt.The snow-melting agent can make snow stop from freezing,make it easier to clear off the road,and allow traffic to flow smoothly.But it also brings about some hidden dangers.In the spring of 2003,over 300 000 trees in Beijing urban districts died.After analyzing soil around these trees,experts discovered that the salt content of these soils was 392 times higher than normal.Where did the excessive salt come from?After investigating,forestry experts found that when clearing snow in the winter,people usually heap snow containing snow-melting agent at trees’ roots,and that when the snow melts,this agent penetrates the soil and increases its salt content.The snow-melting agent indirectly killed the trees.
Statistics show that during a heavy snow in 2002,over 1000 tons of snow-melting agent was scatterred on streets in Beijing.Snow water containing a large amount of snow-melting agent got into the soil through sewers.
In addition,salt in the snow-melting agent can expedite the corrosion of steel bars in concrete buildings and cause the concrete to crack and peel,shortening the life of roads.
Scientists and government officials are required to solve traffic problems caused by heavy snows as soon as possible and at the same time try to reduce the negative effects of the snow-melting agent.This is a difficult problem placed before them.Related authorities have framed some local criteria to regulate the production and use of snow-melting agents.
Now,more harmless snow-melting agents are being developed.Now that even snow-melting agents that meet today’s criteria must still be used carefully,we have to rely more on our manpower and machines to clear off snow.
This year,in addition to using snow-melting agents,Beijing will use a large number of snow vehicles to clear snow on roads.In more places,citizens are mobilized to clear snow with their hands.This may be a test of a city’s civilization level.
小题1:Salt is a snow-melting agent while _________ is a cleaning agent.
| A．water | B．soap | C．a washing-machine | D．a housewife |
| A．the side effect of snow-melting agent |
| B．a case of damage to trees caused by snow-melting agent |
| C．the results of using snow-melting agent |
| D．the uses of snow-melting agent |
| A．use snow-melting agent as much as possible |
| B．only use more harmless snow-melting agent |
| C．encourage people to clear snow with their hands |
| D．use more snow vehicles |
| A．a newspaper | B．a magazine on latest findings |
| C．a book on salt | D．a magazine on environmental protection |
小题1:The diagram is mainly about ______.
| A．the food chain of the animal | B．the system of energy flowing |
| C．how to get food for man | D．the growth of the energy |
| A．Oxygen is released into the air. | B．Food is provided for animals. |
