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．

分析 本文主要講述了一位老師給他的學(xué)生們講了游牧民族沒(méi)有充分利用資源，沒(méi)有過(guò)著綠色環(huán)保生活的故事．老師講完故事的后，學(xué)生們都有所啟發(fā)．從此以后，他們每一個(gè)人都過(guò)著綠色環(huán)保的生活．作者寫(xiě)這篇文章是為了告訴我們要節(jié)約使用資源和能源，過(guò)綠色環(huán)保的生活．

解答 41．C 細(xì)節(jié)理解題，根據(jù)第一段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，可知在開(kāi)始的時(shí)候，人們是游牧民族；他們不會(huì)呆在同一個(gè)地方很長(zhǎng)時(shí)間．相反，他們會(huì)到處游走，尋找食物，故選C．
42．D理解推斷題，根據(jù)第二段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．可知游牧民族在學(xué)會(huì)種植和飼養(yǎng)動(dòng)物后，愿意定居下來(lái)，故選D． 
43．A細(xì)節(jié)理解題，根據(jù)第三段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；可知老師知道這個(gè)學(xué)生的想法是很正常很合理的，故選A．
44．B 推理判斷題，根據(jù)倒數(shù)第二段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．可知游牧民族的生活是不環(huán)保的．而這些學(xué)生們盡可能地循環(huán)利用資源，他們的行為是非常環(huán)保的，故選B．
45．B 推理判斷題，本文講述了游牧民族對(duì)資源的不充分利用，告訴我們要節(jié)約使用資源和能源，過(guò)綠色環(huán)保的生活，故選B．

點(diǎn)評(píng) 本文考察學(xué)生的邏輯推理能力，要求學(xué)生根據(jù)文章所述事件的邏輯關(guān)系，對(duì)未說(shuō)明的趨勢(shì)或結(jié)局作出合理的推斷；或根據(jù)作者所闡述的觀點(diǎn)理論，對(duì)文章未涉及的現(xiàn)象、事例給以解釋．學(xué)生首先要仔細(xì)閱讀短文，完整了解信息，準(zhǔn)確把握作者觀點(diǎn)．

8．When a patient calls for help at Seton Medical Center，"Hi，Mr．Rogers，can I help you？"says a nurse； it's never a problem finding the nurse．It's because they all wear locator tags that are part of a wireless system that tracks their movements on the floor．"You can even tell when they are walking down the hallway．"says James Hattori．
This system made by Hill-Rom uses infrared（紅外線的）signals to detect when nurses enter a room to answer a call．The Hill-Rom devices look like a mini computer mouse．Some hospitals are putting them in nurses'kitchens．Staff can talk and listen through a wall unit to nurses or even to patients in other rooms．"We can put the time we were spending hunting staff down，trying to find and locate them to much better use，"says a staff member from Seton．Hill-Rom says it has systems installed in more than 850 U．S．hospitals．
Some nurses worry that the devices will be used to listen in on conversations and scrutinize their movements．"I'm not wearing mine．I will still meet my patient's needs but I will not wear this badge．"Annette Bearden is among dozens of nurses at Eden Medical Center who staged an active protest two months ago and hid their badges though they were later recovered．"You know it makes me not feel like a professional．It makes me feel like that someone has to watch me to make sure I am doing my job．"
"The biggest reason we installed this technology is because our old call system is about 25 years old，"says a hospital manager．For hospitals this is a case of technology allowing，perhaps forcing people to better make use of their time．Officials at Eden don't deny they monitor how long it takes nurses to respond to calls but say their main concern is patient care．"I think it is one tool that we can use in measuring overall performance but by itself it is not a valid disciplinary tool，"says an Eden spokesperson．
Eden is expanding its system with hopes the nurse will eventually accept the new technology，but back at Seton where it's been in place for about two years，there is no uneasiness．"Once the staff actually find out how advantageous it can be for them and the patients，well，actually it became very popular．"
In Castro Valley，California，the Eden Medical Center spent almost three hundred thousand dollars to install the Hill-Rom systems on two floors．Eden hopes to get more of the systems for other floors．
 
73．Why is it easy to find a nurse at Seton Medical Center？B
A．The nurses are on television．
B．The nurses wear locator badges．
C．Every patient has his/her own nurse．
D．Each room has a telephone．
74．How can the staff talk to their patients when they are not in the same room？C
A．With hand signals．     B．Through microphones in the pocket．
C．Through a wall unit．   D．With infrared signals on the doors．
75．According to the passage，the underlined word"scrutinize"（paragraph 3）probably meansA．
A．watch closely        B．see inside
C．scan word by word    D．make right
76．How did the nurses at Eden Medical Center react to the badges？D
A．The nurses really liked the badges．
B．They threw the locator badges away．
C．They refused to work．
D．They protested and concealed the badges．
77．According to the administrators of the hospital，Eden Medical Center，the application of the Hill-Rom devices mainly aims atD．
A．introducing modern technology 
B．a(chǎn)dding a tool for discipline 
C．replacing the old call system 
D．improving the service for patients．

15．When you're a parent to a young child，you spend a lot of time talking about feelings：about having to share，about being disappointed because you may not have a cookie instead of broccoli （綠花椰菜），about the great injustice of a parent pressing the elevator button before the child has a chance to．
And in a parenting culture that's increasingly concerned with centering children's needs above all else，mothers and fathers have become skillful at talking about their kids'feelings while masking their own．But new research suggests that parents who hide their negative emotions are doing their children，and themselves harm．
A study published this month says that when parents put on a faux-happy （假開(kāi)心） face for their kids，they do damage to their own sense of wellbeing and authenticity．
"For the average parent the findings suggest when they attempt to hide their negative emotion expression and overexpress their positive emotions with their children，it actually comes at a cost：doing so may lead parents to feel worse themselves，"researcher Dr Emily Impett，says．
It makes sense that parents often fall back on amping up （擴(kuò)大） the positivity for the sake of their children-there are a lot of things in the world we want to protect our kids from．But children are often smarter than we expect and are quite in tune with what the people closest to them-their parents-are feeling．
There was a time about a year or so ago，for example，when I received some bad news over the phone； I was home with my four-year-old and so I did my best to put on a brave face．She knew immediately something was wrong though，and was confused．
When I finally let a few tears out and explained that Mom heard something sad about a friend，she was，of course，just fine．My daughter patted my shoulder，gave me a hug，and went back to playing．She felt better that she was able to help me，and the moment made a lot more sense to her emotionally than a smiling mom holding back sobs．I was glad that I could feel sad momentarily and not have to work hard to hide that．
Relaying positive feelings to your children when you don't feel them is a move the researchers called high cost-that it may seem like the most beneficial to your child at the time but that parents should find other ways of communicating emotions that"allow them to feel true to themselves"．
But this is also about children seeing the world in a more honest way．While we will want to protect our children from things that aren't age-appropriate or harmful，it's better to raise a generation of kids who understand that moms and dads are people too．
58．What is the typical behavior of parents when they bring up their children？C
A．Allowing their children chances to do things themselves．
B．Expressing their dissatisfaction with their children．
C．Hiding their true emotions from their children．
D．Sharing their favorite food with their children．
59．If parents put on a faux-happy face，D．
A．their children will be protected
B．their children will be taken in
C．they will feel happy as a result
D．they will undergo worse feelings
60．The author mentioned the example of her daughter to illustrateB．
A．children are not so clever as parents think
B．children can often understand parents'true feelings
C．it's meaningful for parents to always look positive
D．it's necessary to expose children to harmful things
61．We can conclude from the passage thatB．
A．protecting children from age-inappropriate things is important
B．it makes sense for children to know their parents'negative feelings
C．children will admire their parents more because of being protected
D．separation from negative feelings helps children see the world honestly．

1．Surfing the net when you should be finishing a work report，changing clothes when you have a train to catch，or perhaps even lying in bed when you've promised yourself you'll work out．Sound familiar？You aren't alone．We all procrastinate （拖延） sometimes，especially when it comes to things we aren't really fond of．And while the number of activities we delay doing in any given week varies from person to person，it's fair to say that none of us is super-efficient 100percent of the time．
A study revealed that we spend about 218minutes procrastinating every day，which amounts to 55days of lost time each year．We might not think these figures particularly worthy of worry，but when we look at the overall impact of procrastination on our lives，it's a different story．Not only does this cost financial loss，it also affects peace of mind．And procrastination isn't just a money thief--it steals time too．In general，people who continually put things off are unhappier，as well as being less wealthy and healthy．
So why do we do it？"When we avoid taking action，we're really avoiding pain，"explains psychiatrist （精神病學(xué)家） Phil Stutz．For most of us，pain avoidance isn't limited to one situation．It applies to almost anything that's painful．Most of us try our best never to leave a comfort zone．That's why we sacrifice something much more valuable：time．"Our time on earth is limited，"Stutz adds．"Every moment is an opportunity we'll never have again．Procrastinators act as if they have all the time in the world．But deep down，they know they're wasting parts of their life．The trouble is，most of them don't know how to free themselves．"
One way he says we can reach this level of freedom is by overcoming the pain of avoidance using daily visualization （想象）．"Picture the pain you're avoiding as a black cloud in front of you，"Stutz says．"Notice how you're fed up with the ways this pain has held you back in life，and tell yourself that you're determined to conquer it．Then it's time to get through the cloud and to the other side-where you're free．"It is obvious that this tool works when we want to procrastinate．We then get into the habit of moving"towards"pain instead of away from it．
In addition to the fact that procrastinators suffer more health problems，procrastination also destroys teamwork and personal relationships because it shifts the burden of responsibilities onto others．So next time you think about putting something off，remember the impact it will have．Experts insist：procrastinators can change their behavior，it takes a lot of self-work but in the end，it's worth the effort．And start today，not tomorrow．

41．The writer begins the passage byC．
A．presenting abnormal things
B．a(chǎn)sking related questions
C．mentioning habitual activities
D．comparing different opinions

A．leads to different results for different persons
B．is likely to have bad effects on people's life
C．may not be particularly worthy of concern
D．tends to cause unhappiness among people
43．According to the passage，people procrastinate because theyB．
A．get accustomed to taking action
B．prefer to stay in the comfort zone
C．don't know how to free themselves
D．a(chǎn)re not aware of the limited time

A．overcome it mentally
B．a(chǎn)void the pain
C．take some self-work    
D．reach the freedom
45．What's the writing purpose of the passageD？

8．Sports can help you keep fit and get in touch with nature．However，whether you are on the mountains，in the waves，or on the grassland，you should be aware that your sport of choice might have great influence on the environment．
Some sports are resource-hungry．Golf，as you may know，eats up not only large areas of countryside，but also tons of water．Besides，all sorts of chemicals and huge amounts of energy are used to keep its courses（球場(chǎng)）in good condition．This causes major environmental effects．For example，in the dry regions of Portugal and Spain，golf is often held responsible for serious water shortage in some local areas．
There are many environment-friendly sports．Power walking is one of them that you could take up today．You don't need any special equipment except a good pair of shoes；and you don't have to worry about resources and your purse．Simple and free，power walking can also keep you fit．If you walk regularly，it will be good for your heart and bones．Experts say that 20minutes of power walking daily can make you feel less anxious，sleep well and have better weight control．
Whatever sport you take up，you can make it greener by using environment-friendly equipment and buying products made from recycled materials．But the final goal should be"green gyms"．They RYe better replacements for traditional health clubs and modern sports centers．Members of green gyms play sports outdoors，in the countryside or other open spaces．There is no special requirement for you to start your membership．And best of all，it's free．

32．Which of the following is the author most probably in favor of？A
A．Cycling around a lake．    
B．Motor racing in the desert．
C．Playing basketball in a gym．
D．Swimming in a sports center．
33．What do we know about golf from the passage？D
A．It produces chemicals and wastes．
B．It is popular in Portugal and Spain．
C．It causes water shortages around the world．
D．It needs water and electricity to keep its courses green．
34．The author uses power walking as an example mainly becauseC．
A．it is an outdoor sport    
B．it improves our health
C．it uses fewer resources 
D．it is recommended by experts
35．The author writes the passage toB．
A．show us the function of major sports
B．encourage us to go in for green sports
C．discuss the major influence of popular sports
D．introduce different types of environment-friendly sports．
