16．Don't you just love ice skating every winter？I am sure that since winter is approaching，your skates are set to come out，just waiting to be used．Impress your friends with your new trick on how to ice-skate backwards with the help of these tips．
Stand straight
The first thing that you need to do is，stand straight．（36）G，if you feel that you are falling backwards．Don't worry； this happens to all．
Confidence is what you need
The most important step while learning how to skate backwards，is having enough confidence in yourself and in what you are doing．How can you achieve this？By practice．One of the important ice skating tips and techniques is that if you feel that you are losing your balance，then scissor（做剪式運動）your skates．（37）C．
Maintain speed
Try sculling（滑）with one skate while rolling in a straight line with the other．（38）A．Now bring the skate which you are using to scull，and then again，repeat the same process．Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling．
Now，try the same thing using the other foot．
（39）D．
Once you are confident that you can scull with either foot，the next thing that you have to do is increase your speed．Try some of your own tricks now．Scull with either foot or with both at the same time．
Scull and be aware
While you keep one foot straight，keep sculling with the other．You can do that with both feet at the same time．（40）F，but don't get so involved that you don't see where you are going．If you are not watching your back，you might just bang against something or someone．

A．That is，keep pushing yourself backwards with an outwards stroke（滑動）
B．While going backwards，just get used to the feeling of moving backwards
C．Keep practicing this till you are confident about it
D．Increase your speed now
E．One must be brave enough to learn to ice-skate backwards
F．Concentrate on what you are doing
G．Just put your chin up and slightly bend your knees．

分析 本文提及了冬天即將來臨，提供了滑雪的幾種技巧．

解答 36-40 G C A D F
36．G 第一個建議是站直了，Just put your chin up and slightly bend your knees符合此段的大意．
37．C 第二段提到的建議是要有信心．cofidence是關鍵詞．
 38．A 根據(jù)第一句話"Try sculling（滑）with one skate while rolling in a straight line with the other"可知答案為A．
 39．D 在這段里"the next thing that you have to do is increase your speed"這句話暗示標題為提高速度．
40．F 由前句提到兩只腳都可以劃，但是要集中注意可知，下句是關于注意力集中的．

點評 做這種七選五閱讀時，首先需要快速的瀏覽全文，把握文章的主旨大意；其次要學會帶著問題到文中相應的地方，通過細節(jié)閱讀來尋找或概括答案；最后理清作者的寫作思路也非常重要．

1．Tropical fish hobbyists will tell you their tanks are a source of relaxation，but recent research suggests the fish might disagree．
Many American households contain a fish tank，whose average size is less than 10gallons．Yet a study comparing the behavior of common freshwater fish found that those kept in such small tanks were more aggressive than those in larger ones and were more likely to fight．
"If people kept dogs in these conditions，they'd be put in prison，"said the author，Ronald Oldfield．"In larger tanks，the fish were not in continuous eyesight of each other．They were swimming around，checking everything out rather than beating each other，"he added．"It's something we should think about．"
The study consisted of two experiments．In one，Dr．Oldfield tested the effects of overcrowding by keeping tank size constant（不變）while increasing the number of fish．In the other，he tested environment by placing three fish in tanks of different sizes．He then recorded their behavior at least two hours after feeding，to eliminate （排除） competitive behaviors related to food．While aggression seemed to remain constant regardless of the number of fish in a tank，it dropped off considerably once the fish were placed in a l00-gallon tank with several plants and rocks to form shelters．
The findings confirmed what he found when observing Midas in the wild．"If you go out and observe these fish swimming in a river，"he said，"they're not aggressive at all，really．"This conclusion is not news to Justin Muir，the owner of a fish tank business．"More volume of water is always better．It keeps the fish healthier，and the tank is more stable．"

41．We can conclude from the study thatC．
A．The fish in small rivers are more likely to fight than those in larger ones．
B．If you keep fish in tanks of less than 10 gallons，you'll be put into prison．
C．People haven't paid enough attention to the feeling of fish in smaller tanks．
D．The fish in the wild are more likely to fight than those kept in tanks．
42．The underline word"aggressive"probably meansB．
A．polite         
B．violent          
C．enthusiastic          
D．frightened
43．How was the first experiment performed？A
A．By putting more and more fish in the same tank．
B．By putting fish in tanks of different sizes．
C．By putting some food to test the behavior of fish．
D．By putting fish in a tank with plants and rocks．
44．The two experiments prove thatD．
A．food competition results in the aggressive behavior of fish
B．fish become more aggressive as more fish are put into a tank
C．crowding is the main cause of the aggressive behavior of fish
D．fish become less aggressive when placed in a 100-gallon tank
45．The best title for this passage might beB．
A．Animals'Right to Live at Ease
B．Picture of Relaxation Only if You're Not Inside
C．How to Keep Tropical Fish as Pets
D．How to Deal with Fish's Aggressive Behavior．

2．They say there are three ways to experience the Grand Canyon（科羅拉多大峽谷）：on foot，on mules （騾子） or by air．We chose the first．Up early，my husband and I and our three children couldn't wait to get started．We decided to walk along a lovely path named Bright Angel Trail．
As we set out，I was shocked at how narrow the path was．And I couldn't help noticing that the other tourists weren't like us．They had heavy backpacks，water bottles，and hats．But as usual we were dressed．As the sun rose higher，Arizona's famous heat seemed to roast （烘烤） us．There was no shade and our legs were aching．We decided to go back，with the girl on my back and the boys far behind．By the time we finally got back，we were weak．
The next day，after we'd had a long rest and a good breakfast，we were ready for another view of the Canyon by air．After our last walk，this would be the easiest thing in the world．
We called to each other excitedly as the plane took off and circled around the Canyon．But the smiles on our faces disappeared as the pilot tossed （翻轉(zhuǎn)） the plane around，pretending he was going to hit the ground．I shouted，"STOP，TAKE US BACK!"When we finally arrived back on land，once again our legs were like jelly（果凍）．We hardly spoke as we drove back．
As I said，there are three ways to view the Grand Canyon．We never tried the mules，but personally I'd suggest a fourth：buy yourself a good magazine like National Geographic．That way，you can see the Canyon，without fear or tiredness．
51．How many ways did the author and her family try to experience the Grand Canyon？B
A.1         
B.2         
C.3            
D.4
52．How did the author and her family feel before they first experienced the Grand Canyon on foot？A
A．Excited．      
B．Tired       
C．Bored        
D．Relaxed．
53．Which of the following is NOT the reason why the author and her family gave up their first trip？D
A．They didn't prepare well before the trip．
B．It was too hot in Arizona．
C．There were no shade and their legs wore out．
D．They wanted to make a trip by air．
54．What did the author think of the trip by air？C
A．Comfortable          
B．Relaxing．  
C．Frightening         
D．Interesting．

11．How was it that an American ship came to be sunk by American mines in a port held by American forces？
Built in1931，the luxury liner SS President Coolidge was a 10-year veteran（退伍軍人） of the Pacific before she was pressed into service by the military and converted to carry troops．
On October 26，1942，towards the end of her first year of World War II service，the Coolidge hit an American mine in the east entrance of the Segond Channel on Espiritu Santo，one of the islands of the New Herbrides（now Vanuatu），and sank in 36meters of water．
Though all but two of the 5000officers and men aboard were saved，the loss of the ship was a military scandal．She had escaped the Japanese during the worst part of the war in the Pacific，only to be lost because of a series of disastrous American mistakes．
The master of the Coolidge，Henry Nelson，claimed he hadn't been warned that the harbor was mined．Worse，in terms of wartime security，neither of the two US destroyers the Coolidge had encountered had challenged her．Nor had they relayed the vital information about the mines．"The first warning was from a signal station further in the harbor telling me to stop，that we were approaching danger，"he wrote．
‘I，in turn，stopped the engines and backed the engines，but with the speed we were moving，we still went too far and we struck two mines．I immediately，with the speed we had left，headed the ship to the beach，and ordered"abandon ship"，which was done and completed in 45minutes．'‘No one mentioned to me，no one informed me，that there was a mine field in Espiritu Santo．Had there been some knowledge of mines，I never would have approached anywhere visible．'
Captain Nelson was exonerated（免罪） by a court of inquiry but those responsible did not escape blame．The port director's office at Noumea and the inefficiency of an experienced commanding officer of a navy patrol（巡邏隊） and pilot boat were blamed．
Today，the Coolidge is one of the world's best wreck dives．Much of her original luxury decoration remains，including The Lady，perhaps the most photographed underwater icon in the world．Military equipment she was transporting can also still be seen．

（Note：Answer the questions or complete the statements in NO MORE THAN TEN WORDS．）

78．The ship was"pressed into service by the military"suggests that it wasforced into becoming a military ship/pressed into service by the military．．
79．What caused the sinking of the ship？American mines that navy patrol failed to inform the captain about
80．Why did the ship still hit the mines after the captain stopped the engines？Because the speed of the ship made it impossible
81．Why was the sinking of this ship a"scandal"？Because she sank for hitting her own navy's mines/Because she sank for a series of disastrous American mistakes．/Because she sank for American mistakes not for the war．．

1．There has been a dramatic increase in the number of natural disasters over the past few years，and it is assumed that global warming and climate change could cause even more disasters in the future．Some of the world's leading cities are facing disasters like floods and heat waves．
Lcmdoii
 London's flood defenses are getting older．Since 1982，the Thames Barrier has protected the city from the threat of flooding，but it was only designed to last until 2030 and close once every two or three years．About 26 years later the barrier now closes five or six times a year，and according to Environment Agency predictions，by 2050 the barrier will be closed on almost every tide if the problem is not addressed．
 There are 26 underground stations，400 schools，16 hospitals，an airport and 80 billion worth of property in London's flood risk area，so large scale flooding would be disastrous．
 Paris
 Over a six-week period in July and August，2003'，more than 11，400mainly elderly people-died in France from dehydration （脫水）and extremely high body temperature in a deadly heat wave．Heat waves of similar intensity （強度）are expected every seven years by 2050，so what can be done to make sure such a disaster does not happen again？
 One solution is to have air conditioners installed in elderly care homes．But this is considered a short-term solution，as the increase in demand for electricity also increases carbon emissions （排放）．
 In Paris the local authorities are encouraging architects to design new types of buildings such as the building"Flower Tower"，which uses a covering of bamboo to aet as a natural air conditioner．Shan^im Shanghai is the fastest growing city on Earth．It has a population of 18 million and is only 4 meters above sea level．Sea level is predicted to rise by 20cm within the next century．
 An estimated 250，000 people move to Shanghai every year hunting for jobs，placing extra demands on energy consumption．China relies heavily on coal-fired power stations，but these emissions increase temperature and，in turn，Waraieii seas increase the risk of typhoons．
72．What problem should be settled now in London？D
 A．How to protect the city's property．
 B．Where to build its flood defenses．
 C．How to use the Thames Barrier to protect the city．
 D．How to improve the function of its flood defenses．
73．Which of the following can NOT solve the heat wave disaster in Paris according to the passage？C
 A．Limiting the amount of carbon emissions from factories or cars．
 B．Having air conditioners installed in elderly care homes．
 C．Forbidding the city to build"Flower Tower"．
 D．Encouraging architercts to design new types of buildings．
74．The major threat to Shanghai is  according to the passage．B
 A．the increasing population and the need for jobs
 B．rising sea level and typhoons
 C．extremely high temperature and rising sea level
 D．extra demands on energy consumption and typhoons
75．The purpose of the passage is to．D
 A．tell us how to protect the big cities
 B．give advice on how to defend against natural disasters
 C．explain what causes flood and heat waves
 D．warn us of the increasing natural disasters in big cities．

5．Everywhere man is altering the balance of nature．He is facilitating the spread of plants and animals into new regions，sometimes deliberately，sometimes unconsciously．He is covering huge areas with new kinds of plants，or with houses，factories，slag-heaps and other products of his civilization．He exterminates some species on a large scale，but favors the multiplication of others．In brief，he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million．
Many of these changes which he has brought about have had unforeseen consequences．Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade，or that the provision of pot cacti for lonely settlers'wives would have led to Eastern Australian being overrun with forests of Prickly Pear？Who would have prophesied that the cutting down of forests on the Adriatic coasts，or in parts of Central Africa，could have reduced the land to a semi desert，with the very soil washed away from the bare rock？Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa，measles into Oceania，very possibly malaria into ancient Greece？
These are spectacular examples； but examples on a smaller scale are everywhere to be found．We make a nature sanctuary for rare birds，prescribing absolute security for all species； and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested．We see，owing to some little change brought about by civilization，the starling spread over the English country-side in hordes．We improve the yielding capacities of our cattle； and find that now they exhaust the pastures which sufficed for less exigent stock．

31．The following examples exceptD reflect man altering the balance of nature．
A．man is covering huge areas with new kinds of plants
B．man is facilitating the spread of animals into new regions．
C．man is killing some species on a large scale
D．man is getting to know the importance of keeping the balance of nature．
32．What had a piece of Canadian waterweed cause？B
A．Eastern Australian was overrun with forests．
B．Half the waterways of Britain blocked for a decade．
C．In parts of central Africa，the land reduced to a semi desert．
D．Disease-sleeping has been caused．
33．What have spread diseases？C
A．Disease-sleeping sickness．      B．Measles．
C．Improved communications．        D．Malaria．
34．We make a nature sanctuary for rare birds butA．
A．some common and hardy kind of bird multiplies
B．rare kinds multiply
C．a(chǎn)ll bird multiply
D．no bird multiply
35．The main idea of the passage isD．
A．that man is deliberately destroying the balance of nature
B．that man has foreseen the consequences of altering the balance old nature
C．that improved communications have changed history
D．that man is altering the balance of nature．
