Will Mars Become a Second Earth?
In the science fiction films “Total Recall” and “Red Planet”, certain scenes show the characters taking deep breaths of Martian air as though they were on Earth.
In both films, Mars has undergone(經(jīng)歷)an artificial process of “terraformation” to transform(轉(zhuǎn)變)its atmosphere and environment and enable life forms to breathe its air.
The idea of transforming a planet such as Mars in order to make it as habitable(可居住的)as the Earth is not restricted to science fiction films and novels.It has also been proposed by some of the greatest astrophysicists(天體物理學(xué)家)and scientists of the 20th century, such as Carl Sagan.
Such a notion is highly idealistic, since current levels of technology and Mars' natural resistance to change would make it an extremely long process.Anyone hoping to play a Martian football match on a genuine grass pitch in the open air will probably have to wait about another 100 000 years!
問題導(dǎo)入:NASA(美國(guó)宇航局)is planning to make the Mars into a second earth.Is this plan practical?Some people think it a wonderful idea.But others have quite a different opinion.They believe that to make the Mars fit to live on will cost a great deal of money, time and energy.
Here comes the question.Can human make the Mars into a second earth?Debate it with your classmate in two groups.
pros:
Debater 1:In my opinion, it is practical to make the Mars into a second earth.Because lots of research finds out that there are many similar points between the earth and the Mars.And the science technology is so advanced today, I think it is practical if human devote themselves to exploring it.
Debater 2:I don't agree with him that it is not practical to make the Mars into a second earth.
Here is some evidence to show that there used to be lives on the Mars and it is possible to live there again.________________________
Debater 3:I think his evidence is some guess or prediction of some scientists that hasn't been tested.________________.
Debater 4:
In conclusion, ________ Thank you.
Cons:
Debater 1:In my opinion, it is not practical to make the Mars into a second earth.Because ________________
Debater 2:I think some of his evidence is incomplete or unilateral(片面的) _____________.
I have some evidence that it is impossible for human to live on the Mars.__________
Debater 3:I don't think your reasoning is reasonable.________________.
Debater 4:In a word, ________, Thank you.

The effects of rapid travel on the body are actually far more disturbing than we realize. Jet Lag is not a psychological consequence of having to readjust to a different time zone. It is due to changes in the body’s physiological regulatory mechanisms, specifically the hormonal systems, in a different environment.
Now that we understand what Jet Lag is, we can go some way to overcome it. A great number of the body’s events are scheduled to occur at a certain time of day. Naturally these have to be regulated, and there are two regulatory systems which interact.
One timing system comes from the evidence of our senses and stomachs, and the periodicity we experience when living in a particular time zone. The other belongs in our internal clocks (the major one of which may be physically located in a part of the brain called the suprachiasmatic nucleus) which, left alone, would tie the body to a 25-hour rhythm. Normally the two timers are in step, and the surroundings tend to regularize the internal clocks to the more convenient 24-hour period.
If, however, you move the whole body to a time zone which is four hours different, the two clocks will be out of step, like two alarm clocks which are normally set together, but which have been reset a few hours apart. Whereas the two clocks would normally sound their alarms together, now they ring at different times. Similarly, the body can be set for evening while the sun is rising.
In time the physiological system will reset itself, but it does take time. One easily monitored rhythm is palm sweating. A man flown to a time zone different by 10 hours will take eight days to readjust his palm sweat. Blood pressure, which is also rhythmical, takes four days to readjust.
What can we do about it? It is not feasible to wait four days until the body is used to the new time zone. Fortunately there is a short cut. It relies on two things-the power of the stomach to regulate the timing of other events, and the pharmacological actions of coffee. The basic assumptions are:
Coffee delays the body clock in the morning, and advances it at night. Coffee at mid-afternoon is neutral. Protein in meals stimulates wakefulness, while carbohydrates promote sleep. Putting food into an empty stomach helps synchronize the body clock.
46. What is jet lag associated with?
A. Psychological change. B. Physiological change.
C. Inexperience of rapid travel. D. Unfamiliar environment.
47. What helps us to adjust to a 24-hour rhythm?
A. Alarm clock. B. Suprachiasmatic nucleus in our brain.
C. Signals from outside of the body. D. Our senses and stomachs.
48. What do we know from the fifth paragraph?
A. A person moving to a different time zone will suffer from high blood pressure.
B. A person moving to a different time zone will sweat a lot.
C. Moving to a different time zone will affect both palm sweat and blood pressure.
D. If the rhythm of blood pressure and palm sweat are not in step, there will be jet lag.
49. What should we do if we want to stay awake?
A. To take coffee at three o’clock in the afternoon.
B. To have meals that contain lots of protein.
C. To have some carbohydrate drinks.
D. To stop putting food into our stomach.
50. How can we cure jet lag?
A. To sleep for days. B. To wait for self-recovery.
C. To drink tea. D. To get something to eat.

C
How has smoking been controlled in recent years?
People were asked to stop smoking in a range of public places—such as doctors’ surgeries, cinemas, theatres and churches—over the second half of the 20th century but it was after the King’s Cross Underground fire on November 18, 1987, caused by a cigarette end which resulted in 31 deaths, that restrictions on smoking in public places gained rapid and widespread acceptance.
How did a ban on smoking in public places come into place?
In 1998 the Smoking Kills White Paper set out a national strategy to reduce smoking prevalence (流行) and passive smoking, including in public places. The measures were voluntary and poorly carried out. After a public conference in England in 2004, the Government decided to choose for lawmaking. Scotland went first, with a ban in 2006, followed by the other nations a year later.
What is the current law?
Any person who smokes in enclosed public places, including pubs, offices, on public transport and work vehicles, is breaking the law. It does not extend to private houses. It is also an offence for people in charge of premises (營(yíng)業(yè)場(chǎng)所) to permit others to smoke in them.
How was it received?
It was welcomed by most organizations—except for some pub owners and restaurateurs. Many workplaces in the UK had already introduced smoke-free policies consistent with the legislation (法律,法規(guī)) before it was carried out, while others have gone beyond its basic requirements.
All railway facilities, including platforms, footbridges and other areas—whether or not fitting the definition of an enclosed public space—are covered, as are all football grounds and some cricket and athletics stadiums. School grounds are not required to be smoke-free under the legislation, but the majority now are.
How has it been forced?
Compliance (服從) in public premises has been high, with inspections suggesting that 99 per cent of places were sticking to the rules. The number of people charged for smoking in cars has been very low, which was due to the problems defining and identifying “work” vehicles. They said that a total ban on smoking in vehicles would end this confusion.
Has it improved health?
Studies in early adopters of the law, including in Scotland, suggest a reduction in hospital admissions for heart disease, which has been shown to be linked to passive smoking. There is also strong evidence of improved rates of smoking end and a drop in the number of cigarettes consumed by those who continue to smoke.
63. When did the first law come out to ban smoking in public places?
A. 1987. B. 1998. C. 2004. D. 2006.
64. Which of the following behaviors may NOT be against the law?
A. Jack often smokes in the office when he is alone.
B. A taxi driver is smoking with a lady in his car.
C. Tom smokes while thinking of his future at home.
D. Max smokes for relaxation during time-out in the stadium.
65. Who might feel unhappy about the law according to the article?
A. A restaurant owner. B. A company manager. C. A car owner. D. A policy maker.
66. What can you infer from the article?
A. Most heart diseases have been proved to be linked to passive smoking.
B. A new law will soon come out with a total ban on smoking in vehicles.
C. The 1987 fire has convinced more people that smoking is bad for health.
D. Most of the school grounds are not smoke-free, as it is not banned in the law.

As the price of a college degree continues to rise, there's growing evidence that the monetary(貨幣的) payoff isn't quite as big as often advertised. The best estimate now is that a college degree is worth about $300,000 in today's dollars--nowhere near the million figure that is often quoted.
"That million number has driven me crazy!" says Sandy Baum, a Skidmore economist who studied the value of a college degree for the College Board last year.
Baum's research showed that college graduates earn, on average, about $20,000 a year more than those who finished their educations at high school. Add that up over a 40-year working life and the total differential is about $800,000, she figures. But since much of that bonus is earned many years from now, taking away the impact of inflation means that$800,000 in future dollars is worth only about $450,000 in today's dollars.
Then, if you remove the cost of a college degree--about ,$30,000 in tuition and books for students who get no aid and attend public in-state universities--and the money a student could have earned at a job instead of attending school, the real net value in today's dollars is somewhere in the $300,000 range, a number confirmed by other studies.
But, especially these days, that still makes a college degree one of the most lucrative investments a person can make, Baum notes.
Better yet, college graduates can go on to earn advanced degrees, which return even bigger payoffs. The average holder of a bachelor's degree earns about$51,000 a year, Baum calculates. But those who've gone on to earn MBAs, law degrees, or other professional degrees earn about $100,000 a year.
In addition, Baum found that there are plenty of other rewards for a degree. The quality of the jobs college graduates get is far better, for example. College graduates are more likely to get jobs with health insurance. And it is easier for them to find and hold jobs. The unemployment rate for college graduates was just 2.2 percent last year, half the unemployment level of those with only high school diplomas.
There are lots of other nonmonetary benefits as well. College graduates are healthier, contribute more to their communities, and raise kids who are better prepared academically, studies show.
Other researchers have found that the payoff of a degree is especially lucrative for students from low-income families, since the education and degrees give them a chance to break out of low-paying careers.
【小題1】What can be inferred from Para 1 ?
A.The payoff of a college degree is still big enough to match the advertised. |
B.It’s more and more difficult to get a college degree. |
C.The return of a college degree is less than often quoted. |
D.A college degree is worth about one million dollars. |
A.a(chǎn)ttractive | B.worthless | C.a(chǎn)pproachable | D.balanced |
A.By getting jobs with health insurance immediately. |
B.By going on for higher degrees. |
C.By breaking out of low-paying jobs. |
D.By contributing more to his or her community. |
A. According to Baum's research, high school graduates earn more than those who have college degrees. |
B. College education is enough to ensure you a good life. |
C. Nonmonetary benefits from the degree attract students more than monetary ones. |
D.Students from low-income families still think degrees are profitable to change their life. |
