8.For most people,shopping is still a matter of wandering down the street or loading a cart in a shopping mall.Soon,that will change.Electronic commerce (trade) is growing fast and will soon bring people more choices.There will,however,be a cost:protecting the consumer from being cheated will be harder.Many governments therefore want to apply street regulations to the electronic world.But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation.
Consumers in rich countries have grown used to the idea that the government takes responsibility for everything from the stability of the banks to the safety of the drugs or their rights to refund when goods are faulty.But governments cannot enforce national laws on businesses whose only presence is on the screen.Even in a country where a clear right to compensation exists,the on-line customer in Tokyo,say,can hardly go to New York to get a refund (退款) for a clothes purchase.
One answer s for government to cooperate more:to recognize each other's rules.But that requires years of work and volumes of detailed rules.And plenty of countries have rules too fanciful (稀有的) for sober countries to accept.There is,however,another choice.Let the electronic businesses do the regulation themselves.They do,after all,have a self-interest in doing so.
In electronic commerce,a reputation for honest dealing will be a valuable competitive asset.Governments,too,may compete to be trusted.For instance,customers ordering medicines on-line may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA's  rules are too strict,and buy from Switzerland instead.
Customers will still need to use their judgment,but precisely because the technology is new,electronic shoppers are likely for a while to be a lot more cautious than customers of the normal sort.And the new technology will also make it easier for them to complain when a company lets them down.In this way,at least,the advent(出现) of cyberspace may argue for fewer consumer protection laws,not more.
32.In case an electronic shopper bought faulty goods from a foreign country,what could he do?D
A.Refuse to pay for the purchase.
B.Go to the seller and ask for a refund.
C.Appeal to consumer protection law.
D.Complain about it on the Internet.
33.In the author's view,businesses would place a high emphasis on honest dealingbecause in the electronic worldC.
A.international cooperation would be much more frequent
B.consumers could easily seek government protection
C.a good reputation is a great advantage in competition
D.it would be easy for consumers to complain
34.We can infer from the passage that in licensing new drugs the FDA in the United States isC.
A.very cautious     
B.very quick
C.very slow    
D.rather careless
35.According to the author,what will be the best policy for electronic commerce?C
A.Close international cooperation.
B.Strict Consumer protection laws.
C.Self-regulation by the business.
D.Government protection.

5.Vacations are important.We need to take time out from work to relax,and just be
ourselves.(56)E We should all be allowed to leave our jobs behind us-at least for a few weeks each year-and just have fun.This might be something as simple as reading a good book in front of a warm fireplace through to travelling to the most interesting places on our planet.Whatever we fancy doing is worth taking time out for.
Workplace stress is on the rise.(57)A These include disease,depression and even death.We all seem to be running from one place to the next,never finding out where we want to go in the first place.I intend to break that trend in the coming days.(58)G I will sleep late,write,watch movies,drink the occasional glass of wine,and eat to my heart's content ignoring calorie counting.My plan is to just enjoy the fleeting moments of being alive.
(59)C Spend your next vacation the way you want.Do what will restore your mental health.You're very valuable to the people who are close to you,and to those who depend on it.Like it or not,we are all interdependent in this great life of ours.
You are valuable.Just remember that the next time you look at the mirror and take a deep breath.Remind yourself that there will never be anyone like you ever on this earth again.(60)F All you have to do is just ask yourself what you want to do.

A.With it come many health problems.
B.When you finally get home you'll be greatly refreshed.
C.I challenge each one of you to do the same.
D.Draw up a detailed plan so you can see more.
E.Life is not all about work,or at least it shouldn't be.
F.And only you know how to vacation your way.
G.For my next holiday,I will do all the things that I love doing.
4.Many of us dream about getting a good job,but you can never predict for sure which questions you'll be asked in a job interview.However,some are so commonly asked that you should expect to hear them,and more importantly,spend time preparing your responses to them instead of leaving them to chance.
1."Why are you leaving your current job?"
Interviewers ask this,because sometimes the question produces relevant information.They may learn if you were fired for poor performance,if you can't get along with your boss or if you are actually out of job.Most interviewers won't care too much about the details.Whatever answer you'd give,keep in mind that your answer needs to be truthful,and employers may check the facts.
2."What salary range are you looking for?"
It's essential to prepare an answer for this question ahead of time.You need to research the market rate.Employers who ask for your salary history want to figure out how much you should be earning now.One option is to respond with your salary expectations based on reality,for example,depending on benefits.
3."Why do you think you are good at this job?"
To get an offer,you need to show not just that you're qualified to do the job,but that you'd be good at it.That means you need to talk about"evidence"in your past that shows your success in each of the key qualifications(合格).Get well prepared for questions like"Give me an example of a challenge you faced and how you solved it."
4."What are your weaknesses?"
Interviewers ask this question because they want to make sure your weaknesses won't get in the way of you doing the job well.Be prepared to honestly discuss your weak spots.What have you struggled with in the past?What have managers encouraged you to do differently?This type of answer will help you have an honest dialogue with the employer to figure out if this role is the right fit for you.
53.By asking the first question,the interviewers intend toA.
A.get some related information about the interviewee
B.judge what kind of person the interviewee actually is
C.learn if the interviewee was fired by the boss
D.confirm whether the interviewee is honest or not
54.To get a job offer,the interviewee needs toC.
A.be realistic and truthful  
B.demand a suitable sum of money
C.give evidence of qualifications        
D.tell about how you'll do the job properly
55.What is the best way to talk about your weaknesses in a job interview?B
A.Trying to avoid talking about your past.
B.Honestly discussing your weaknesses.
C.Talking about your plan to avoid them.
D.Claiming they won't affect the work.
3.The news that Zhou Hao chose to drop out from Beijing University and transfer to a technical college raised a heated discussion among high school students.The following are some of the students'views.
Fan Xianjie:I support Zhou's choice.Zhou went to Beijing University because of the pressure from his parents and teachers,who ignored his interests.Now he has made his own choice to drop out and do what he really wants to do.His bravery deserves our respect and understanding.
Dan Jinyu:I do respect Zhou's decision.But If I were him,I would definitely have followed my heart at the very beginning,because dropping out and then learning something new wastes a lot of time.Zhou has now got what he wanted.But not everyone is as brave as him.So we should think twice and try our best to reach our goals when making decisions.
Luo Jiayin:Zhou's surprising choice is mostly because of his parents'ignorance toward his interests in the first place.Parents should give their kids more freedom to choose what their kids really want instead of what they think is right.
Luo Zhouhai:Zhou is brave to pursue his dream and has the right to choose a major that he is really interested in.Nowadays,there are still many people who value famous universities'diplomas more than a person's actual skills.As our society develops,this situation will change and more and more Zhou Haos will appear.
Zhao Chengyi:This incident should make all the universities in China reflect on themselves.Why did Zhou choose to transfer to a technical college?Apart from his own personal reasons,Beijing University's lack of options in its subjects also contributed to the drop-out.To prevent such things from happening in future,universities should pay more attention to students'voices.
Tao Ruyi:I think Zhou Hao might not have made a sensible decision.He must have made great efforts to get admitted to Beijing University.It was a pity that he dropped out.
49.How many students totally supported Zhou's dropping out?A
A.Two.
B.Four          
C.Five       
D.Six
50.What can we infer from Zhao Chengyi's words?C
A.It was Zhou Hao's parents that were to blame for the incident.
B.It was wrong for Zhou Hao to drop out from Beijing University.
C.Universities should think of more options in their subjects for their students.
D.Beijing University should try to bring out students'potential to learn more.
51.The author's attitude towards Zhou's incident isD.
A.supportive 
B.negative      
C.critical      
D.unmentioned
52.What do you think is the best title for this passage?B
A.Kids'interests should be greatly valued
B.Different opinions about Zhou's incident
C.Zhou's incident shocked the college students
D.Zhou's bravery deserves respect and understanding.
2.On Christmas Day in 2003,Nancy Brown went to see the film Cheaper by the Dozen at an AMC movie theater.The theater was (21)C.When the film was over,Brown,then 63,followed the large audience through the hall toward the (22)A.As she passed the Concession Stand(小卖部),she (23)D tripped and fell to the ground.

20.Winners of the third Healthy Lunchtime Challenge came to the White House on Friday,July 18,for a Kids'State Dinner hosted by First Lady Michelle Obama.They all came from America for a meal that featured a selection of kid-created recipes (食谱).
       Mrs.Obama told the winners and their parents that they set a strong example.The First Lady advised winners to"pay it forward"like last year's winner from Delaware,10-year-old Braeden Mannering.He helped the homeless get food and clean water.
President Barack Obama made a surprise appearance at the event.He spoke about the First Family's favorite food."You guys are leaders in your schools,"the president told the kids,"and you're helping to teach people the importance of good nutrition (营养),the importance of putting good food in your bodies so that you're living healthy,active lives."
The Healthy Lunchtime Challenge was open to young people between the ages of 8 and 12 and their parents.The competition received about 1,500 recipes.They were judged in the first round on nutritional value,taste,creativity and affordability,and the story behind the recipe.Chefs then prepared the recipes in a second round of judging.The winners were chosen by a group of judges that included great chefs and nutritionists,etc.
Before heading for the White House,the winners and their families visited the National Museum of American History to see the Food exhibit and received healthy breakfast bags from the Walmart Foundation.After the dinner,the group headed for a tour of the White House Kitchen Garden.They all had a wonderful time.

19.We experience different forms of the Sun's energy every day.We can see its light and feel its warmth.The Sun is the major source of energy for our planet.It causes the evaporation (蒸发) of water from the oceans and lakes.Sunlight also provides the energy used by green plants to ma ke their own food.These green plants then provide food for all organisms (生物) on the Earth.
    Much of the energy that comes from the Sun never reaches the Earth's surface.It is either reflected or absorbed by the gases in the upper atmosphere.Of the energy that reaches the lower atmosphere,30% is reflected by clouds or the Earth's surface.The remaining 70% warms the surface of the planet,causes water to evaporate,and provides energy for the water cycle and weather.Only a tiny part,approximately 0.023%,is actually used by green plants to produce food.
    Many gases found in the atmosphere actually reflect heat energy escaping from the Earth's surface back to the Earth.These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving.They are therefore called greenhouse gases.
    When sunlight strikes an object,some of the energy is absorbed and some is reflected.The amount reflected depends on the surface.For example,you've probably noticed how bright snow is when sunlight falls on it.Snow reflects most of the energy from the Sun,so it contributes to the low temperatures of winter.Dark-coloured surfaces,such as dark soil or forest,absorb more energy and help warm the surrounding air.
24.According to the passage,the root cause for weather changes on the Earth isC.
A.the atmosphere surrounding the Earth         
B.water from oceans and lakes
C.energy from the Sun                          
D.greenhouse gases in the sky
25.Only a small part of the Sun's energy reaches the Earth's surface because most of it isC.
A.absorbed by the clouds in the lower atmosphere
B.reflected by the gases in the upper atmosphere
C.lost in the upper and lower atmosphere
D.used to evaporate water from the oceans and lakes
26.We learn from the passage thatA.
A.all living things on the Earth depend on the Sun for their food
B.a forest looks dark in winter because it absorbs solar energy
C.only 0.023% of the energy from the Sun is made use of on the Earth
D.greenhouse gases allow heat energy to escape from the Earth's surface.
