Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water — whether for drinking, agriculture, industry or the raising of fish will always have to be met. Given that premise（前提）, there are two basic routes we can go: more access to water or more engineering solutions (more dams, for instance).
Looking at the engineering solution first, a lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal regime of the river, or rather, the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the next century, governments will have no excuse for their ignorance. The engineers ability to control water flows has created new kinds of unpredictability. Dams in Africa have meant fewer fish, less grazing and less agriculture — none of which were expected.
The challenge for the next century is to find new means of controlling water. Although GM technology will allow us to breed better dry-land crops, there is no market stimulation for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World?
This brings us to the key issue in any discussion of water: money. In the next century, just consider the problems of water supply in Mexico City or Delhi. If you’re rich, you drink mineral water and may even have a swimming pool — yet millions in such cities can’t get safe drinking water. People talk about the coming water crisis. I believe we have one now. It is a water crisis for the poor.
Habits are a funny thing. We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine.“Not choice, but habit rules the unreflecting creatures,”William Wordsworth said in the 19th century. In the ever-changing 21st century, even the word“habit”carries a negative meaning.
So it seems contradictory to talk about habits in the same context as innovation (创新). But brain researchers have discovered that when we consciously develop new habits, we create parallel paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.
Rather than dismissing ourselves as unchangeable creatures of habit, we can instead direct our own change by consciously developing new habits. In fact, the more new things we try, the more creative we become.
But don’t bother trying to kill off old habits; once those ruts of procedure are worn into the brain, they’re there to stay. Instead, the new habits we deliberately press into ourselves create parallel pathways that can bypass those old roads.
“The first thing needed for innovation is attraction to wonder,”says Dawna Markova, author of The Open Mind.“But we are taught instead to‘decide’, just as our president calls himself‘the Decider’．”She adds, however, that“to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities.”
“All of us work through problems in ways of which we’re unaware,”she says. Researchers in the late 1960s discovered that humans are born with the ability to approach challenges in four primary ways: analytically, procedurally, collaboratively (合作地) and innovatively. At the end of adolescence, however, the brain shuts down half of that ability, preserving only those ways of thought that have seemed most valuable during the first decade or so of life.
The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us use our innovative and collaborative ways of thought.“This breaks the major rule in the American belief system—that anyone can do anything,”explains M. J. Ryan, author of the 2006 book This Year I Will…and Ms. Markova’s business partner.“That’s a lie that we have preserved, and it fosters commonness. Knowing what you’re good at and doing even more of it creates excellence.”This is where developing new habits comes in.Brain researchers have discovered that.

My House
My mother moved a lot when she was growing up on account of Grandpa being in the army. She hated having to adjust to new schools and make new friends. That’s why I thought she was joking when she put forward the idea of moving. But she was completely serious. “For just the two of us,” my mother said, “an apartment in the city will suit our needs much better.” Personally, I think she’s lost her mind. I guess I can understand why she would want to move, but what about me and what this house means to me?
I suppose if you l
ooked at my house, you might think it was just another country house. But to me it is anything but standard. I moved into this house with my parents ten years ago. I can still remember that first day like it was yesterday. The first thing I noticed was the big front yard. To me it seemed like an ocean of grass—I couldn’t wait to dive in. The backyard was full of gnarled (扭曲的, 粗糙的) and scary trees that talk on windy nights. But I grew to like them and the shadows they cast in my room. My father and I even built a small tree house, where I often go to remember all the wonderful times we had before Father’s death.
This house is special—maybe only to me—but special nevertheless. It’s the little seemingly insignificant things that make this house so special to me: the ice-cold tile floors that make me tremble on midnight snack runs; the smell of my father’s pipe that still exists; the towering bookcases of my mother; the view outside my bedroom window.
This house holds too many memories, memories which would be lost if we gave it up.Why did the author’s mother decide to move?
| A．Because she hated the countryside. |
| B．Because Grandpa was on constant move. |
| C．Because Dad’s death made her lose her mind. |
| D．Because she thought a city flat more fit for them. |
What impressed the author when she first moved into the house?
| A．The tree house. | B．The big trees. | C．The cold floors. | D．The green grass. |
How did the author let us feel that the house was special to her?
| A．By arguing whether the house was standard. |
| B．By explaining why the house suited their needs. k.&s~5*u |
| C．By describing the small things related to her house. |
| D．By comparing the differences between country and city life. |
My mother moved a lot when she
was growing up because of ________.
| A．Grandpa being in the army. | B．their family’s liking moving |
| C．the life’s need | D．Mother’s work |
In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Bad events like "serious illness of a family member" were high on the list, but so were some helpful life-changing events like marriage.
When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress －it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically (戏剧性的) affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women's magazines ran titles like "Stress causes illness".
If you want to stay physically and mentally healthy the articles said avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous , many — like the death of a loved one — are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方) for staying away from chances as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The idea that all stress makes you sick also takes no notice of a lot of what we know about people. It supposes we' re all vulnerable and not active in the face of the difficult situation. But what about human ability and creativity? Many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom and physical and mental pressure.

In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill m the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.
Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe (严格的) over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child's own happiness.
As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach (说教), their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled.
A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
