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

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another product out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.

“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors(投资人) happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time, and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.

While it’s probable that Apple is surely in a testing stage for its next smartphone, consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.

“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.

When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored products when it revamped (更新，翻新）its iPod line last fall, so it is understood that it would want the new change with its smartphone, as well”.

“I wouldn’t be surprised if the new iPhone becomes available in some new colors,’’ he said. “That could be done pretty cheaply, and it would give Apple a new marketing angle.”

1.According to Ramon Llamas, Apple always ______.

A. tries to please its investors

B. rushes to put new products to market

C. ignores the fierce market competition

D. does things as planned

2.As for the next iPhone, Colin Gibbs didn’t mention ______.

A. the stage of its being tested

B. the rough time of its being released

C. the function to be improved

D. the wide variety of its color

3.What’s Colin Gibbs’ attitude towards the next iPhone?

A. Disapproving.    B. Indifferent (漠不关心的).      C. Doubtful.     D. Objective.

4.This passage is presented in the form of ______.

A. stories            B. comments           C. advertisements         D. debates
