The Israeli farmers who pioneered the revolutionary technology known as drip irrigation weren’t trying to solve one of the world’s most urgent problems．They were just trying to survive．They lived in the desert，and they didn’t have enough water to grow their crops．

In its simplest form，it was little more than a pipe with holes in it．But behind each hole was a hi-tech dripper that let out just the fight amount of water．Snaked along a row of crops so that the holes were positioned directly above the roots，the pipe could direct each precious drop of water directly to the plants，getting a bigger harvest while using a very small amount of the water．

Over time，the farmers improved upon the technology，perfecting the drippers that regulated the flow of water，and connecting the pipelines to computers that could determine exactly how much water each plant needed and when．

If the global population kept growing，the rest of the world would increasingly resemble their little community in the desert．So they began selling their irrigation systems in other parts of the world，eventually expanding to more than 110 countries．Netafirm，the company says it’s lifting people out of poverty and conserving water at a time when the importance of doing so has never been clearer．

The mass adoption of drip irrigation won’t save the world by itself．To avoid the coming catastrophe，nearly everybody will，in some way，have to do more with less，perhaps through accepting and using other new technologies．Otherwise，it’s going to get ugly．

1.Why is drip irrigation called“the revolutionary technology”?

A．It saves the world all by itself．

B．It is controlled by computers．

C．It makes irrigation more effective．

D．It provides deserts with water．

2.What does“one of the world’s most urgent problems”in Paragraph l refer to?

A．Lacking water． B．Lacking labor．

C．Lacking food． D．Lacking energy．

3.How does the drip irrigation help farmers with crops?

A．By drilling holes on the pipes．

B．By regulating water via drippers.

C．By snaking pipes along the crops．

D．By placing pipes just above roots.

4.Which of the following will be the best slogan for Netafirm to sell the irrigation systems?

A．Less water；More harvest．

B．New technology；New world．

C．More grain；Less starvation．

D．Water saving；World surviving．
