　　Invented in Turkey and patented by Nanopool, a German company, the spray-on liquid glass might become one of the most useful inventions in the field of nanotechnology．The product was tested at the Saarbrücken Institute for New Materials．

　　It is worth mentioning that the invention is transparent and non-poisonous．The liquid glass can protect any type of surface from damages caused by water, UV radiation, dirt, heat, and bacterial infections．Besides, it is flexible and breathable, which means that the liquid glass can be applied on plants and seeds as well．Researchers found that the spray greatly increases the resistance of plants to bacteria-caused diseases．The trials also showed that the sprayed seeds grew faster．

　　Depending on the type of surface that is to be covered, researchers can add water or ethanol to the spray．Scientists say that their latest invention has a long-lasting anti-bacterial effect．The spray produces a coating that is just 100nm thick．Trials by food processing plants in Germany have concluded that foods covered with the glass can store longer than those stored in normal condition．

　　According to Neil McClelland, UK project manager with Nanopool, due to its capabilities, the spray-on liquid glass can become one of the most useful inventions around the world, ending up being used by a lot of industries that will cover their products．At present, the invention is being used by a train company and a hotel chain in the UK, as well as a hamburger chain in Germany that are carrying out tests of the liquid glass for various uses．

　　The spray-on liquid glass was also tested in a Lancashire hospital, where it showed “very promising” results, being used to cover medical equipment and bandages．The invention could be also used on clothing, because it cannot be seen by the naked eye, thus clothes could become stain resistant．Due to its unique characteristics, the liquid glass can be used to cover bathrooms, sinks and many other surfaces in the home．According to the researchers, the spay-on glass can last for a year．It is expected to hit the DIY stores across Britain at a price of 5 pounds．

(1)

Which of the following about the liquid glass is NOT true?
[　　]
A．	We can still see an object clearly covered with the liquid．
B．	It will cause plants to have some kind of disease．
C．	Plants still have access to oxygen when covered by it．
D．	It can speed up the growth of seeds．

(2)

What does the underlined sentence in Paragraph 3 imply?
[　　]
A．	Water or ethanol must be added to the spray to produce the effect．
B．	The coating of the spray-on liquid is thick．
C．	The liquid glass can protect foods from bacteria．
D．	The long-lasting anti-bacterial effect protects the liquid glass．

(3)

According to Neil McClelland, the spray-on liquid glass _________．
[　　]
A．	are being tested by some industries
B．	are being used by various companies
C．	can be eaten together with hamburgers
D．	are widely used by train companies

(4)

The writer’s attitude towards the application of the new liquid glass is _________．
[　　]
A．	pessimistic
B．	doubtful
C．	cautious
D．	optimistic

(5)

What can be inferred from the passage?
[　　]
A．	We don’t have to wash our clothes with the new invention．
B．	The liquid glass can be used to wash yourself in the bathroom．
C．	The DIY stores will not welcome the liquid glass．
D．	The liquid glass will be widely used in many fields．

答案：1．B;2．C;3．A;4．D;5．D;
解析：

(1)	细节理解题。第二段Researchers found that the spray greatly increases the resistance of plants to bacteria-caused diseases．一句的意思是：研究人员发现这种液体可以大大增加植物对细菌性疾病的抵抗力(resistance)。因此，B项是错误的。
(2)	猜测词义题。a long-lasting anti-bacterial effect意思是“持久的抗菌效果”，anti词缀的意思为“抵抗”。
(3)	细节理解题。从Neil McClelland 所说的话…ending up being used by a lot of industries that will cover their products．At present, the invention is being used…that are carrying out tests of the liquid glass…The spray-on liquid glass was also tested in a Lancashire hospital可知，他希望最终(end up)很多企业会使用液体玻璃；而现在仅仅是在试用。
(4)	作者态度题。从最后两段对液体玻璃前景的描述可见，作者的态度非常乐观(optimistic)。
(5)	推理判断题。从最后两段，尤其是最后一句”It is expected to hit the DIY stores across Britain at a price of 5 pounds．大家估计它将以5磅的价格投入DIY商店”可知答案。

　　In Europe, men do not usually wear skirts. But the Scottish national clothing for men is a kind of skirt. It is called a kilt. The Scottish like to be different. They are also proud of their country and its history, and they feel that the kilt is part of that history. That's why the men still wear kilts at traditional (传统的) dances and on national holidays. They believe they are wearing the same clothes that Scottish men always used to wear.

　　That's what they believe. However, kilts are not really so old. Before 1730, Scottish men wore a long shirt and blanket around their shoulders. These clothes got in the way when the men started to work in factories. So, in 1730 a factory owner changed the blanket into a skirt; the kilt. That's how the first kilt was made.

　　Then, in the late 1700s Scottish soldiers in the British Army began to wear kilts. One reason for this was national sentiment ( = feelings) . The Scottish soldiers wanted to be different from the English soldiers. The British Army probably had a different reason. A Scottish soldier in a kilt was always easy to find! The Scottish soldier fought very hard and became famous. The kilt was part of the fame, and in the early 1800s men all around Scotland began to wear kilts.

　　These kilts had colorful stripes (条纹) going up and down and across. In the 1700s and early 1800s, the color of the stripes had no special meaning. Men sometimes owned kilts in several different colors. But later the colors became important to the Scottish families. By about 1850, most families had special colors for their kilts. For example, men from the Campbell family had kilts with green, yellow and blue stripes. Scottish people often believe that the colors of the kilts are part of their family history. In fact, each family just chose the color they liked best.

　　This is not the story you will hear today if you are in Scotland. Most Scottish people still believe that kilts are as old as Scotland and that the colors are as old as the Scottish families. Sometimes feelings are stronger than facts!

A．soldiers' clothes in Britain

　　Suppose we built a robot(机器人)to explore the planet Mars．We provide the robot with seeing detectors(探测器)to keep it away from danger．It is powered entirely by the sun．Should we program the robot to be equally active at all times?No．The robot would be using up energy at a time when it was not receiving any．So we would probably program it to stop its activity at night and to wake up at dawn the next morning．

　　According to the evolutionary(进化的)theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason．The theory does not deny(否认)that sleep provides some important restorative functions(恢复功能)．It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous．However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us．So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent．

　　The evolutionary theory explains the differences in sleep among creatures．Why do eats, for instance, sleep so much, while horses sleep so little?Surely cats do not need five times as much repair and restoration as horses do．But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep．Horses must spend almost all their waking hours eating, because what they eat is very low in energy value．Moreover, they cannot afford to sleep too long or too deeply, because their survival(生存)depends on their ability to run away from attackers．

(3)

According to the author, we cannot sleep well when we ________．
[　　]

[　　]
A．	need more time for restoration
B．	are unlikely to be attackers
C．	axe more active than homes when they are awake

　　Several years ago, my parents, my wife, my son and I ate at one of those restaurants where the menu is written on a blackboard．After a wonderful dinner, the waiter set the check in the middle of the table．That’s when it happened：my father did not reach for the check．

　　One day I bought a house．One day－what a day!–I became a father, and not too long after that I picked up the check for my own father．I thought then it was a milestone for me．One day, when I was a little older, I realized it was one for him, too, another milestone．
