16．Life for Ron and Joanne Wickham used to be full of soccer games，birthday parties，school plays，and parent-teacher conferences．For most of the past 20 years，they spent their evenings reminding their children to do homework and helping them complete it．Now the evenings are empty except for TV，and the weekends seem to last forever．The children whose activities used to fill their time have moved away and have left empty spaces．The Wickham parents have what is usually called Empty-Nests Syndrome．
Ron and Joanne both work for the Heritage Insurance Company in Ukiah，California．In their mid-50s，they have two children，Anne and Josh．Anne just graduated from California State University-Fullerton and is looking for a banking job in the Bay Area．Josh is still a junior at Claremont McKenna College near Los Angeles，but he can only rarely make the 460-mile trip home to visit his parents．Back in Ukiah，Ron and Joanne often feel the house is too big．"It doesn't really echo，"says Ron，"but it feels like it should．Where is everybody？"
Empty-nesters everywhere know the feeling．They are entering a new stage of life，but they remain tied to their former stage．They are typically between the ages of 48 and 60-still working，still involved in their communities，still rooted．This means they aren't free to travel for entertainment or to pull up stakes and move elsewhere．Generally，they live in the homes where they raised their children．Their daily routines may still echo their full-nest days，with wake-up times meant for driving kids to school or meals that include the children's favorite foods．Therapists point out that Empty-Nest Syndrome doesn't last forever．"Eventually，a so-called empty nest starts to feel normal and new routines develop，"says UCLA psychology professor Jaswant Singh．"Most parents complete this journey just fine，but it usually feels pretty lonely．"

3．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 110countries．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．

32．Why is drip irrigation called"the revolutionary technology"？C
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．
33．What does"one of the world's most urgent problems"in Paragraph l refer to？A
A．Lacking water．  B．Lacking labor．    
C．Lacking food．   D．Lacking energy．
34．How does the drip irrigation help farmers with crops？B
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．
35．Which of the following will be the best slogan for Netafirm to sell the irrigation systems？A
A．Less water；More harvest．    
B．New technology；New world．
C．More grain；Less starvation．
D．Water saving；World surviving．
