阅读下面短文，从每小题所给的四个选项中，选出一个最佳答案。

　　Human beings use a little less than half the water available(可利用的) worldwide. Yet occurrences (happen) of shortages and droughts(干旱) are causing hunger and poverty (poor) in some areas, and industrial and agricultural by products are polluting water supplies. Since the world's population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis(危机).

　　But that doesn't have to be the outcome. Water shortages do not have to trouble the world－if we start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic view. We can no longer afford to consider water a actually free resource of which we can use as much as we like in any way we want.

　　Instead, far all uses except the domestic (home) demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.

　　Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small scale projects, such as gathering rainfall in depressions(凹地) and pumping it to nearby cropland.

　　No matter what steps governments take to provide water more efficiently, they must change their legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central organization to coordinate(协调) water policy.

1．What is the real cause of the possible water crisis?

[　　]

A．Only half of the world's water can be used.

B．The world population is increasing faster and faster.

C．Half of the world's water resources have been polluted.

2．According to the author, the water price should ________.

[　　]

A．be reduced

B．meet the local people's demand

C．show its real value

D．be changed according to different situation

3．The author says that in some hot and dry areas it is advisable to ________.

[　　]

A．build big lakes to store water

B．build small and cheap irrigation systems

C．construct big pumping stations

D．channel water from nearby rivers to cropland

4．In order to make full use of the water supply, measures should be taken to ________.

[　　]

A．promise full protection of the environment

B．centralize the management of water resources

C．ask governments at all levels to be responsible

D．encourage local and regional of water resources

     I remember a time I went shopping on my first visit to Macau. Coming from cold and cloudy England, I
was prepared for the sun and dressed in a T-shirt and a short skirt. Not having much chance to enjoy the sun
in the UK and having naturally fair skin, my legs are very white. In the UK this is not a fashionable (时尚的)
look at all. Most women spend every sunny day out in the sun trying to get darker skin. The darker the skin,
the better the look.
     As I walked around one shop, two shop assistants didn't take their eyes off me the whole time, talking
quietly in Chinese. I began to feel uncomfortable and asked my friend if we could leave. After we left the shop,
she asked me what was wrong. I was embarrassed that they were talking about my white skin. My friend
laughed."They weren't laughing at you. They were saying how nice your legs are. Many Chinese women want
to have white skin like yours. In fact, there are many beauty products in the shops to make skin whiter and a
lot of money is spent on them."
     It just goes to show that we always think what others have is better. The grass is always greener on the
other side. If the women of the West and East thought the same way, Western women wouldn't spend so
much money on cream that makes skin darker and women from the East wouldn't need to use cream that
makes skin whiter.

     A mobile phone service which makes your handset scream when it's been stolen has been started,
with its makers claiming it could put an end to mobile theft altogether.
     The Remote XT system uses software to link customers' mobile phones directly to a secure remote
server, which stores all their data from phone numbers to text messages and e-mails. If the owner's phone
is lost or stolen, they can dial a 24-hour call centre and have it registered. The handset is then disabled,
and cannot even be used if a new SIM card is put in. At the same time, the system sets off an alarm
sounding like a high-pitched(尖声的) scream, which can only be stopped by removing the battery.
     Existing data is also wiped off the phone but, because the information has been stored centrally,
as soon as the victim gets a news phone, the system designers said.
     "By making mobiles unusable to anyone but the rightful owner the phones become worthless and we
will see the market for stolen handsets stopped once and for all," said Mark Whiteman, managing
director of Remote XT. For the moment the system is aimed at business customers and comes with a
fee of 9.99 pounds per month, possibly available to the majority of average users within two years as
mobile technology advances.
      According to the latest UK government statistics, mobile phone theft has risen 190 percent in recent
years, with one third of all UK robberies now solely involving mobile phones.

     Modern inventions have speeded up people's lives amazingly. Motor cars cover a hundred miles
in lithe more than an hour,aircraft cross the world inside a day,while computers operate at lightning
speed. Indeed,this love of speed seems never ending. Every year motor cars are produced which g
o even faster and each new computer boasts(吹嘘)of saving precious seconds in handling tasks.
     All this saves time,but at a price. When we lose or gain half a day in speeding across the world in
an airplane,our bodies tell us so. We get the uncomfortable feeling known as j et lag； our bodies
feel that they have been left behind in another time zone. Again,spending too long at computers results
in painful wrists and fingers. Mobile phones also                    ,according to some scientists；too much
use may put harmful radiation into our brains,a consequence we do not like to think about.
     However,what do we do with the time we have saved? Certainly not relax,or so it seems. We are
so accustomed to constant activity that we find it difficult to sit and do nothing or even just one thing at
a time. Perhaps the days are long gone when we might listen quietly to a story on the radio,letting
imagination take us into another world.
     There was a time when some people's lives were devoted simply to the cultivation(耕耘)of the land
or the care of cattle. No multi tasking there；their lives went on at a much gentler pace,and in a familiar
pattern. There is much that we might envy about a way of life like this. Yet before we do so,we must
think of the hard tasks our ancestors faced:they farmed with bare hands,often lived close to hunger,and
had to make tools from wood and stone. Modern machinery has freed people from that primitive
existence.
1. What's the passage mainly about?(within 10 words)

2. List the difficulties our ancestors met according to the text. (within 15 words)
①
②
③
3. Fill in the blank in the 2nd paragraph with proper words or phrases.

4. Why do we make new products more and more time-saving according to Paragraph 1 of this passage?

     The Internet has opened up a whole new online world for us to meet, chat and go where we've never
been before. But just as in face-to-face communication, there are some rules of behavior that should be
followed when online.
     The basic rule is simple: treat others in the same way you would want to be treated. Imagine how
you'd feel if you were in the other person's shoes. For anything you're about to send: ask yourself, "Would
I say this to the person's face?" If the answer is "no", rewrite and reread. Repeat the process till you feel
sure that you'd feel comfortable saying the words to the person's face.
     If someone in the chat room is rude to you, your instinct (本能反应) is to fire back in the same manner.
But try not to do so. You should either ignore the person, or use your chat software to block their messages.
If it was caused by disagreement with another member, try to fix the situation by politely discussing it.
Remember to respect the beliefs and opinions of others in the chat room.
     If you do decide to tell someone in the chat room about a mistake, point it out politely. At the same time,
if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.
     It is not polite such as their age, sex, and marital status. Unless you know the person very well, and you
are both comfortable with sharing personal information, don't ask such questions.

     [1] Queuing, warm beer and afternoon tea-what do they have in common? They are all part of British life.
Or so I thought. However, the ability to queue for long periods of time, once believed to be a typical traditional
characteristic of the British, is no longer tolerated by people in the UK, according to a survey done by the
Payments Council. It would seem they are no longer prepared to wait in line.
     [2] Once upon a time, queuing was seen as normal. During the second World War, everyone had to queue
up to receive their daily ration (配给) of foods. In fact, if you didn't stand up and wait in line with all the others,
it was uncivilized (不文明).The famous English double-decker buses, with only one entrance, might also help
explain why queuing was seen as a part of life. Almost always, there is a queue to get on.
     [3] But perhaps the British are tired of being pushed by the Spanish, the Italians or the French as they
queue up to get a table at a restaurant. The people of these other European countries have more than one
entrance to their buses, which could explain their more relaxed attitude to the queue.
     [4] Two minutes is now the longest time most British are prepared to stand and wait. But could it be that
the Internet, which allows us to carry out tasks quickly, is the main reason why British people are no longer
prepared to queue? As the Internet has become more popular among shoppers, impatience with queuing has
increased.
     [5] "Used to buying without delay, customers are even abandoning purchases rather than wait their turn,"
says Stuart Neal of Barclaycard. "Shoppers are also less likely to queue for longer if the item they are buying
is of low value." Perhaps I will have to replace "queuing" with"impatience" in my list of things I associate with
the British.
