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 this premise (前提), there are two basic routes we can go; more equal access to water or better engineering solutions.

Look at the engineering solutions 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 changes of the river—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 near future, governments will have no excuses for their ignorance.

The engineers’ ability to control water flows has created new kinds of unpredictability, too. Dams in Africa have meant fewer fish, less grazing and less floodplain (洪泛区) agriculture, none of which were expected. And there average economic life is assumed to be thirty years. Dams don’t exist forever, but what will replace them is not clear.

The challenge for the future is to find new means of controlling water. Although GM technology(转基因) will allow us to breed better dry-land crops, there is no market 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?

1.What’s the main idea of this passage?

A．The engineering solutions to water resource and their limitation.

B．The challenge for the future.

C．The basic means of controlling water.

D．The challenge for developing crops.

2.The author suggests that governments will have no excuse for their careless ignorance in the future because _____.

A．The ecological destruction will be known to the public by researchers

B．The ecological destruction will no longer be a problem in the future

C．The future is an information age

D．Governments will face greater challenge in the future

3.Which of the following statements is NOT true for meeting our basic needs for water?

A．Water resource should be used more reasonably.

B．More dams should be built in river basins.

C．More wetlands should be protected from destruction.

D．More dry-land crops could be developed in Africa.

4.The last sentence probably implies that _____.

A．No one will invest in developing locally appropriate crops in Africa

B．Researchers have no interest in developing dry-land crops

C．Research on locally appropriate crops in the Third World may be profitable

D．There is less water resource in the Third World

Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.

Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.

The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.

Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here's where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles —making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles—so it appeared to be smaller than the real smaller orange circle.

When young children aged 4 to 6 looked at these tricky pictures, they weren't fooled—they were still able to find the bigger circle with roughly the same accuracy(准确性) as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.

As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they're more likely to fall for this kind of visual trick.

1.Doherty and his team of scientists did an experiment to evaluate_____________.

A. children's and adults' eye-sight

B. people's ability to see accurately

C. children's and adults' brains

D. the influence of people's age

2.When asked to find the larger circle,_____________.

A. children at 6 got it wrong 79 % of the time with no gray ones around

B. only adults over 18 got it right 95% of the time with gray ones around

C. children at 4 got it right about 79 % of the time with gray ones around

D. adults got it right most of the time with gray ones around

3.According to the passage, we can know that_____________.

A. a smaller orange circle appears bigger on a white background

B. an orange circle appears bigger than a gray one of the same size

C. a circle surrounded by other circles looks bigger than its real size

D. a circle surrounded by bigger ones looks smaller than its real size

4.Why are younger children not fooled?_____________.

A. Because their brain can hardly notice related things together.

B. Because older people are influenced by their experience.

C. Because people's eyes become weaker as they grow older.

D. Because they are smarter than older children and adults.
