7．He is not wealthy； on the contrary，he has been in heavydebt（債）．

分析 他不富有，相反，他負(fù)債累累．

解答 debt 考查固定短語．根據(jù)句意：他不富有，相反，他負(fù)債累累．be in debt是英語的固定短語"負(fù)債累累"，所以答案填debt．

點評 英語中的固定短語，既不能添詞，也不能少詞，是固定的，要求同學(xué)們在平時記憶準(zhǔn)確，然后根據(jù)句意找出記憶中的固定搭配，做出正確的答案．

17．One day，Mr．Arnold was teaching a lesson，and things were going as normally as ever．He was explaining the story of human being to his pupils．He told them that，in the beginning，men were nomads （游牧）； 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．It also meant that people could reain living in one place，and this made it easier to set about tasks that would take a long while to finish，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 clever 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 fisherman 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？
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 o the afternoon talking about what they could do to show how to be more civilized （文明的）．
The next day everyone attended class wearing a green T-shirt，with a message that said"am not a nomad！"
And，from then on，they set about showing that indeed they were not．Every time they knew they needed someting，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 farm．
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．

27．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．
28．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 and keeping animals
29．The teacher thought Lucy's argument wasA
A．reasonable             B．unbelievable
C．puzzling               D．shocking
30．Which of the following agrees with the message"I am not a nomad"（Paragraph 7）？B

B．People use recycled materials as much as possible．
C．Fishermen move elsewhere when there is no fish left．

19．In a little-known part of the counter-terrorism （反恐怖主義） world，one of the most effective detection systems is a 600-pound animal that works for about 20pounds of fish a day．
Since the 1960s，the United States and a handful of other countries have trained dolphins and sea lions to detect sea mines and swimmers，and to recover worn--out torpedoes （魚雷） and testing objects used in naval （海軍的） exercises．
The U．S．Navy kept its Marine Mammal Program a secret until the 1990s，and this spring CNN became one of the first members of the media to witness firsthand how the program works．
The program trains about 75Pacific bottlenose dolphins，with natural biosonar （生物聲納） that tracks better than any manmade device； and 35California sea lions，with very good underwater eyesight．
Not only do these trained marine mammals track and save millions of dollars in U．S．military equipment，they are also helping to save lives．The Navy won't reveal whether the dolphins and sea lions have effectively stopped terrorists attempting to do harm to the U．S．
A key part of the training program is teaching these mammals how to stop potentially unfriendly swimmers．The program is also positioned to defend against swimmer terrorist attacks as well．
In the digital age，it seems that there should be more advanced approaches to guard the Navy's most expensive things．But according to Rothe，the program director，nothing in today's high-technology world can compete with these mammals'biosonar abilities．"I hope that one day there is a robot or a UUV （un-manned underwater vehicle） that makes the mammal program out of date，"he said．"But right now this is the best thing out there．"
25．The U．S．Marine Mammal Program trained marine mammals toA．
A．stop dangerous swimmers
B．catch 20pounds of fish a day
C．destroy sea mines
D．fire torpedoes
26．What can we learn from the last paragraph？A
A．The trained dolphins are the best way of protection available to the U．S．Navy．
B．There will be dolphin-like robots in the future according to Rothe．
C．The mammal program will become useless soon．
D．Rothe has no faith in today's high technology．
27．Which of the following is TRUE according to the text？D
A．Many countries have trained sea animals for counter-terrorism．
B．The Marine Mammal Program was a secret until the 1960s．
C．The trained sea animals have already stopped some terrorists．
D．The U．S．Navy has trained both dolphins and sea lions．
