分析 既然航班因?yàn)樘鞖獠缓靡呀?jīng)被取消了，那么我們不妨坐火車(chē)去吧．

解答 答案：C
句意表達(dá)的是原因，引導(dǎo)原因狀語(yǔ)從句；after之后，although盡管，now that既然，由于，as soon as一…就…；根據(jù)句意，故選C．

點(diǎn)評(píng) 從屬連詞是連詞的一種，用來(lái)引導(dǎo)名詞性從句和狀語(yǔ)從句．大致可分為三大類(lèi)：that（無(wú)詞義，不做成分）if，whether （表達(dá)是否的意義，但不做句子成分）； 連接代詞：who，whom，whose，what，which，whatever，whoever，whichever（有詞義，在句子中可作主語(yǔ)、表語(yǔ)、賓語(yǔ)）；連接副詞：when，where，why，how，how many，how long，how far，however，whenever，wherever （有詞義，作從句的狀語(yǔ)）．學(xué)習(xí)時(shí)，要注意區(qū)分和掌握．

6．In the United States，30 percent of the people have a"weight problem"．To many people the cause is obvious （明顯的）：they eat too much．But scientific evidence （證據(jù)） does little to support this idea．Going back to America of 1910，we find that people were thinner than today，yet they ate more food．In those days people worked harder physically，walked more，used machines much less，and didn't watch television．
Several modern studies，moreover，have shown that fatter people don't eat more on average than thinner people．A 1979 study of 3，545 London office workers showed that fat people eat less than slim （苗條的） people．
Studies also show that slim people are more active than fat people．A study by a research group at Stanford University found the following interesting facts：
The more the man ran，the greater loss of the body fat．
The more they ran，the greater increase in food intake．
Thus，those who ran the most ate the most，yet lost the greatest amount of body fat．
29．Nowadays many Americans have the problem thatC．
A．they are too slim              
B．they work too hard
C．they are too fat           
D．they lose too much body fat
30．According to the passage，how many people in 900 Americans have a"weight problem"？D
A.150．B.300．C.600．D.270．
31．Is there any scientific evidence to support the idea that eating too much is the cause of a"weight problem"？C
A．Yes，there is plenty of evidence．
B．Of course，there is some evidence to support this．
C．There is hardly any scientific evidence to support this．
D．We are not sure．
32．The Americans in 1910A．
A．a(chǎn)te more food and had more physical activities
B．a(chǎn)te less food but had more physical activities
C．a(chǎn)te less food and had less physical activities
D．had more problems．

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．
