3.Sometime early in the next century,human beings will move to Mars.They will live there for about a year,and then will be replaced with another group of pioneers.Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.
We already know that Mars resembles the earth in many aspects:general size,presence of water,length of day,range of temperatures.These resemblances have caused many people to consider a centuries-long project:to terraform Mars.Terraforming means  altering a planet's surface so that Earth's life forms can survive there.This concept,previously found only in science fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple:add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth's plants and animals in the order in which they developed on Earth.But it will take at least 300years.
Some people think that such a project is too huge for humans to undertake,but there are very good reasons to make the attempt.The earth now contains some 6billion people,and no one has any idea of how many humans the earth can support.Our very existence and numbers are threatening many other species.We also have had some experience with terraforming our own planet:altering the landscape,the atmosphere and the climate.Currently terraforming earth has become a wiser activity as we try to control global warming,air and water pollution,and preserve some natural living places.
While the possibility of such a project is small,it is not impossible.Even if earth-bound societies come and go in the next 300years,the project can continue through the work of the Mars settlers without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to terraform Mars.

14.LOS ANGELES (Reuters)---Onions make you cry,add flavor to food and are talked about a lot for their medicinal benefits.Now the vegetable has another use---powering up green energy.
A new system debuts on Friday that changes onion juice into electricity at Gills Onions,the largest fresh onion processor (加工機(jī)) in the United States.
The Oxnard,California-based company expects its new onion-fueled power to reduce its electric bill by﹩700,000 a year and cut its annual greenhouse gas releasing by up to 30,000 tons.The happy ending to this green energy tale,however,generated another question:how to get rid of onion waste."When we peel an onion,35 to 40 percent of the onion comes off before we have a usable onion.That's the top,tail and skins around the onion before you get to the meat,"said Steven Gill,co-owner of the 25-year-old company.
They used to take the waste to the fields for composting (堆肥) but that became a problem as it cost too much.Ten years ago,Gill started looking at technology for a solution."We ended up destroying the skins as they c ome out of the plant and extracting all the juice,which is very high in sugars,and bacteria love it,"Gill said.
In the new system,bacteria produce methane gas(沼氣) from the juice.The gas then goes to two 300 kilowatt fuel cells,creating enough power for 460 homes.The company expects to get 35 to 40 percent of its electricity from this new system.
The company invested﹩9.5 million in the project and will receive﹩2.7 million from Southern California Gas Co.,a regulated subsidiary of Sempra Energy,as part of a state program to encourage self-contained generation by businesses.In addition to cutting its electric bill,the company will save﹩400,000 in costs of taking the waste to the fields and expects pay-back in six years.
The onion grower now has a new goal:to be a zero-waste facility by 2013.
"We wanted to follow it all the way through and make the full circle,"Gill said.

A.Onions are made use of in America now
B.US company finds a new way to reduce costs
C.Onions are widely used to produce electricity now
D.US company turns onion juice into electricity
42.According to the passage,we can learn that in the pastB.
A.onion waste was a problem for most people
B.a(chǎn) big part of an onion was wasted
C.onions were mainly used as medicine
D.onions were not liked by most people
43.In the new system,onions can be used to produce electricity mainly becauseD.
A.the skins of onions can be destroyed easily
B.the onion waste is taken to the fields
C.a(chǎn) lot of bacteria are put into onions

8.Being the boss might mean more money and challenging work but it can also cause damage to physical and mental well-being,according to a Canadian study.
For years studies have shown people in lower-status jobs generally have higher rates of heart disease and other illnesses and die earlier than those in higher-status positions while job authority has shown no relationship with workers'health.
But University of Toronto researchers,using data from 1,800US workers,found the health of people in higher positions is affected by work as they are more likely to report conflicts with co-workers and say work disturbs their home life.
However,the positive aspects of having a power position at work,such as higher status,more pay and greater independence,seemed to cancel out the negative aspects when it came to people's physical and psychological health.
These latest findings,reported in the journal Social Science & Medicine,suggest that the advantages and disadvantages authority positions basically cancel each other out,giving the general impression that job authority has no health effects.
For the study,the researchers surveyed participants about various aspects of their work,life and well-being.Job authority was judged based on whether a person managed other employees and had power over hiring,firing and pay.
Physical health complaints included problems like headaches,body aches,heartburn and tiredness.Psychological complaints included sleep problems,difficulty concentrating and feelings of sadness,worry and anxiety.
"This isn't to suggest that having authority is‘bad'-in fact,we show it has benefits…but it is important to identify the negative sides and deal with them."researcher Scott Schieman said.
Schieman said conflicts with co-workers or involvement of work into home life may destroy at physical and mental well-being by creating stress.
"These are key stressors that can tax individuals'ability to function effectively,"Schieman said.

56.Work will have a negative effect on job authority's health probably becauseD.
A.they are not fit for their work
B.they have power over hiring and pay
C.they are faced with severe competition
D.they don't get on well with their co-workers
57.Most people don't see that bosses have health effects becauseD.
A.their health problems are not serious enough to see
B.they have enough money to keep themselves healthy
C.their problems are quite different from those of workers
D.the advantages and disadvantages of their status work against each other
58.From the passage we can infer that the study aims toB.
A.warn people not to be a boss for ever
B.remind the boss to deal with the bad effects of their work
C.show that having authority is harmful to one's health
D.prove that being a boss can benefit a lot
59.The best title for this passage might beB.
A.Lower-status can affect health
B.Authority can affect health
C.Positive aspects of a power position
D.Disadvantages of being a boss.

15.If you're a male and you're reading this,congratulations!You're a survivor.According to statistics,you're more than twice as likely to die of skin cancer than a woman,and nine times more likely to die of AIDS.Assuming you make it to the end of your natural term,about 78 years for men in Australia,you'll die on average five years before a woman.
There're many reasons for this--typically,men take more risks than women and are more likely to drink and smoke but perhaps more importantly,men don't go to the doctor.
"Men aren't seeing doctors as often as they should,"says Dr.Gullotta."This is particularly so
for the over-40s,when diseases tend to strike.According to a recent survey,95%of women aged between 15 and early 49s see a doctor once a year,compared to 70%of men in the same age group.
"A lot of men think they're unbeatable,"Gullotta says."They only come in when a friend drops dead on the golf course and they think,Geez,if it could happen to him …"
Then there's the ostrich(鴕鳥(niǎo))approach."Some men are scared of what might be there and would rather not know,"says Dr.Ross Cartmill.
 
"Most men get their cars serviced more regularly than they service their bodies,"Cartmill says.He believes most diseases that commonly affect men could be addressed by preventive check-ups.
"Prevention is cheaper in the long run than having to treat the diseases.Besides,the final cost is far greater,it's called premature death."
 
64.Why does the author congratulate male readers at the beginning of the passage?C
A.They can live longer than they expected.
B.They are sure to enjoy a longer and happier life.
C.They have lived long enough to read this article.
D.They are more likely to survive serious diseases now.
65.Which of the author's statements is the most important reason that men die five years earlier on average than women according to the passage?B
A.Men drink and smoke much more than women.
B.Men don't seek medical care as often as women.
C.Men are more likely to suffer from deadly diseases.
D.Men aren't as cautious as women in face of danger.
66.Which of the following best completes the underlined sentence"Geez,if it could happen to him…"(in Para 4)?A
A.it could happen to me,too.
B.it would be a big misfortune.
C.I should avoid playing golf.
D.I should consider myself lucky.
67.What does Dr.Ross Cartmill mean by"the ostrich approach"(in Para 5)?D
A.A casual attitude towards one's health conditions.
B.A new treatment for certain psychological problems.
C.Refusal to get medical treatment for fear of the pain involved.
D.Unwillingness to find out about one's disease because of fear.

12.Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a common parasite that can be caught from cat litter,a study has found.
Researchers found women infected with the Toxoplasma gondii (T.gondii) parasite(剛地弓形蟲(chóng)),which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables,are at increased risk of attempting suicide.
The study involved more than 45,000women in Denmark.About a third of the world's population is infected with the parasite,which hides in cells in the brain and muscles,often without producing symptoms.
The infection,which is called toxoplasmosis(弓形蟲(chóng)。,has been linked to mental illness,such as schizophrenia(精神分裂癥),and changes in behavior.
The study's senior author Doctor Teodor Postolache,an associate professor of psychiatry(精神病學(xué)) at the University of Maryland School of Medicine in the United States,said,"We can't say with certainty that T.gondii caused the women to try to kill themselves,but we did find a predictive association between the infection and suicide attempts later in life that deserves additional studies."
Doctor Albert Reece,vice president of medical affairs at the University of Maryland,said,"T.gondii infection is a major public health problem around the world,and many people don't realize they're infected.
"Dr Postolache is a leading expert on suicide neuroimmunology(神經(jīng)免疫學(xué)).Suicide is a critically important mental health issue.About one million people commit suicide and another 10million attempt suicide worldwide each year.We hope that this type of research will one day help us find ways to save many lives that now end too early in suicide."
Dr.Postolache's research team at the University of Maryland was the first to report a connection between T.gondii and suicidal behavior in 2009.He is cooperating with researchers in Denmark,Germany and Sweden to confirm and investigate the way leading to this association.
The T.gondii parasite thrives in the intestines of cats,and it is spread through their waste.All warm-blooded animals can become infected through contact with it.Humans can become infected by changing their infected cats'litter boxes,eating unwashed vegetables,drinking water from a polluted source,or by eating undercooked or raw meat.
Not washing kitchen knives after preparing raw meat before handling another food item also can lead to infection.Pregnant women can pass the parasite directly to their unborn babies and are advised not to change cat litter boxes to avoid possible infection.
Babies don't produce antibodies to T.gondii for three months after they are born,so the antibodies present in their blood represented infection in the mothers.The scientists studied Danish health patients to determine if any of these women later attempted suicide,including cases of violent suicide attempts which may have involved guns,sharp instruments and jumping from high places.
The study found that women infected with T.gondii were one and a half times more likely to attempt suicide compared to those who were not infected,and the risk seemed to rise with increasing levels of the T.gondii antibodies.
Dr Postolache noted limitations to the study,such as the inability to determine the cause of the suicidal behavior.
The findings were published online in the Archives of General Psychiatry.
50.The objects of the research are women fromA.
A.Demark B.the USA C.Germany D.Sweden

C.to pass the infection to her unborn baby during a woman's pregnancy
D.to reuse kitchen tools which have been used to cut raw meat
52.What is the consequence if a woman is infected with the parasite in the passage?B
A.Having a high fever.
B.Doing deliberate self-harm.
C.Keeping a depressed mood.
D.Becoming bad tempered.
53.What can be inferred from the passage?C
