　　A scientist who developed a way to calculate(计算) how much water is used in the produciton of anything form a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.
　　Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water(虚拟水)",a calculation method that has changed the nature of trade policy and research.
　　Allan has written seven books and published more than 100 papers.
　　The Stockholm International Water Institute said this idea is now embedded(埋藏) in the production of foods and industrial products.The institute said Allan's work had made a big effect on global trade policy and research,especially in water - scarce(缺水) regions.

    A laser (激光) is used to produce very powerful beams of light. These beams of light are so powerful that they make holes in steel very quickly. Today laser is getting wider and wider use in more and more fields.

    Why is laser so much more powerful than other kinds of light? What makes laser beam so different from other beams?

    Laser is a kind of light and also a form of energy. A laser beam is made up of very short waves. These waves all have the same wavelength. The laser beam keeps going on and off all the time, and is off much longer than it is on. As these changes are very fast, we can not see them. During the time the laser beam is off, the energy for the next burst of light is being built up, so when the beam is on again, it will be a strong burst. And the laser beam doesn’t spread, that is, it doesn’t get wider and wider as other light beams do. This is why the laser beam can keep all of its energy and is so much more powerful than other light beams.

1．The article is about ______.

[　　]

A．light B．a form of energy

C．laser D．light beam

2．Laser beam is ______ other light beams.

[　　]

A．different from B．the same as

C．almost the same as D．made up of

3．Laser ______ any other kind of light.

[　　]

A．is faster than B．is wider than

C．keeps longer than D．is more powerful than

4．Because the laser beam ______, it can keep all of its energy.

[　　]

A．isn’t like other light beams

B．can keep going on and off all the time

C．doesn’t spread

D．can change

5．Which of the following is TRUE?

[　　]

A．Laser is made up of waves of different lengths.

B．The time when the laser beam is on is much shorter than when it is off.

C．Laser is getting wider and wider at present.

D．Light can make holes in steel.

When a consumer finds that something he or she bought is faulty or in some other way does not live up to what the producer says for it, the first step is to present the warranty(保单),or any other records that might help, at the store of buying. In most cases, this action will produce results.

However, if it does not, there are various means the consumer may use to gain satisfaction.A simple and common method used by many consumers is to complain directly to the store manager. In general, the “higher up” the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favour, taking it as true that he or she has a just right.
    Consumers should complain in person whenever possible, but if they cannot get to the place of buying, it is acceptable to phone or write the complaint in a letter.
    Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example,“The left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo(立体音响) does not work.”.
    The store manager may advise the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the expected result, the consumer can go a step further. He or she can threaten to take the seller to court or report the seller to a public organization responsible for protecting consumers' rights.

A. complain personally to the manager       B. show something provable in written form to the store

61. If a consumer wants a quick settlement of his problem, it's better to complain to ____________.
A. a shop assistant            B. the producer    C. a public organization            D. a store manager
62. The most effective complaint about what was bought can be made by ________.
A. showing the fault of it to the producer     B. saying firmly it is of poor quality
C. asking politely to change it                      D. explaining exactly what is wrong with it
63. The passage tells us______.
A. how to make the complaint have a good effect   B. how to settle a consumer's complaint
