14．She's in a hopeless situation，___________ we will keep a very close eye on．（　�。�
A．whereB．whenC．whichD．that

分析 她處在一種絕望的狀態(tài)，我們會(huì)密切關(guān)注（她的狀態(tài)）．

解答 答案：C
題干中we will keep a very close eye on是修飾situation的一個(gè)非限制性定語(yǔ)從句；從句中介詞on缺少賓語(yǔ)，要用關(guān)系代詞．故選C．

點(diǎn)評(píng) 定語(yǔ)從句是一類(lèi)比較重要的復(fù)合句．定語(yǔ)從句關(guān)系詞的選擇要根據(jù)從句的結(jié)構(gòu)來(lái)確定，從句如果缺少主語(yǔ)或賓語(yǔ)，要用關(guān)系代詞；從句結(jié)構(gòu)如果完整，要用關(guān)系副詞．學(xué)習(xí)時(shí)，要注意區(qū)分和掌握．

1．One day，Mr．Arnold was teaching a lesson，and things were going as normally as ever．He was explaining the story of mankind to his pupils．He told them that，in the beginning，men were nomads； they never stayed in the same place for very long．Instead，they would travel about，here and there，in search of food，wherever it was to be found．And when the food ran out，they would move off somewhere else．
He taught them about the invention of farming and keeping animals．This was an important discovery，because by learning to cultivate（耕作）the land，and care for animals，mankind would always have food steadily available．It also meant that people could remain living in one place，and this made it easier to set about tasks that would take a long while to complete，like building towns，cities，and all that were in them．All the children were listening attracted by this story，until Lucy jumped up：
"And if that was so important and improved everything so much，why are we nomads all over again，Mr．Arnold？"
Mr．Arnold didn't know what to say．Lucy was a very intelligent girl．He knew that she lived with her parents in a house，so she must know that her family were not nomads； so what did she mean？
"We have all become nomads again，"continued Lucy，"The other day，outside the city，they were cutting the forest down．A while ago a Gsherman told me how they fish．It's the same with everyone：when there's no more forest left the foresters go elsewhere，and when the fish run out the fishermen move on．That's what the nomads did，isn't it？9，
The teacher nodded，thoughtfully．Really，Lucy was right Mankind had turned into nomads．Instead of looking after the land in a way that we could be sure it would keep supplying our needs，we kept developing it until the land was bare．And then off we would go to the next place!The class spent the rest of the afternoon talking about what they could do to show how to be more civilized．
The next day everyone attended class wearing a green T-shirt，with a message that said"I am not a nomad!"
And，from then on，they set about showing that indeed they were not．Every time they knew they needed something，they made sure that they would get it using care and control．If they needed wood or paper，they would make sure that they got the recycled kind．They ordered their fish from fish farms，making sure that the fish they received were not too young and too small．They only used animals that were well cared for，and brought up on farms．
And so，from their little town，those children managed to give up being nomads again，just as prehistoric men had done，so many thousands of years ago．
41．Why would early humans travel about in the beginning？C
A．To experience different lifestyles．
B．To go sightseeing in different places．
C．To find what they could to feed themselves．
D．To do more exercise to build themselves up．
42．From Paragraph 2，we can know thatD•
A．people got tired of living in the same place
B．people gradually got used to living in cities
C．people spent a long time in learning to keep animals
D．people tended to settle down after learning farming
43．In the teacher's opinion，Lucy's argument wasA
A．reasonable   B．ridiculous  C．puzzling  D．shocking
44．Which of the following agrees with the message"I am not a nomad"（Paragraph 7）？B
A．People eat young fish for its delicious taste．
B．People use recycled materials as much as possible．
C．Fishermen move elsewhere when there is no fish left．
D．Foresters leave the place where wood is not available．
45．The writer tries to make us believe thatB．
A．mankind has been progressing mainly through traveling about
B．it's unwise for mankind to use the land in an uncontrolled way
C．if S quite good for students to learn more about the history of mankind．D．in the beginning men were nomads．
