Could we "terraform" Mars —that is, change its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could.Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers flowing into vast seas.And right here on Earth, we've learned how to warm a planet: just add greenhouse gases to its atmosphere.Much of the CO2 that once warmed Mars is probably still there, in frozen dirt and polar ice caps, and so is the water.
Most of the work in terraforming, says NASA scientist Chris Mackay, would be done by life itself. "You don't build Mars," Mackay says."You just warm it up and throw some seeds." Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere; by warming the planet, they would release the frozen CO2, which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow.Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession (系列) of ecosystems ?first bacteria and lichens (地衣), which survive in Antarctica, later mosses (苔蘚), and after one thousand years or so, redwoods.Getting breathable oxygen levels out of those forests, though, could take thousands of years.
However, Mars is in no immediate danger.Some space scientists recently recommended going to the moon or an asteroid (小行星) first, and pointed out the space agency lacks the funds to go anywhere.It didn't estimate the cost of gardening a dead planet.
72.What is the most essential to make Mars fit for living?
A.Turn ice into flowing water.          B.Clean the dirty atmosphere.
C.Make the atmosphere more suitable.    D.Go to the moon or an asteroid first.
73.What does the author think of the idea ofterraforming Mars?
A.We could do it.                            B.We couldn't do it.
C.We should do it.                           D.We shouldn't do it.
74.In the botanist's opinion, man needs to __________.
A.enable Mars to clean its atmosphere
B.build a greenhouse on Mars
C.send some people to settle on Mars
D.cultivate ecosystems from lower to higher life form
75.What is the best title for the passage?
A.Making Mars the New Earth.           B.A Good Way to Change the Universe
C.Humans' Great Power.                     D.Terrible Science and Technology.

第三部分任務(wù)型閱讀(滿分10分)
Romantic novelists rarely fail to include in their writings that special moment when two strangers look into each other's eyes across a crowded room and feel the tingle of desire. Now these writings have now been validated(證實(shí))by science, for experts have discovered that eye-to-eye contact in fact leads to a burst of activity in the reward center of the brain.
Neuroscientists at University College London asked eight female and eight male volunteers to look at photos of the faces of 40 different people who were either looking at the camera or gazing to one side.
While the volunteers looked at the pictures, they were given a scan with functional magnetic resonance imaging(磁性共振成影儀器), which measures increased blood flows to the various parts of the brain and thus provides a "map" of cerebral activity(大腦活動).
The volunteers were then asked to rate the attractiveness of each face, and their score was matched against the scan.
The result: when volunteer had direct eye contact with the face, there was an increase of activity in the ventral striatum(腹面紋狀體), a central part of the brain that anticipates reward or pleasure. But if the eyes did not meet, there was no activity in that brain area at all. The activity increase occurred regardless of the gender of the face in direct eye contact.
However, there was a bigger-than-usual increase if the person giving the eye was found to be attractive. Activity in the ventral striatum surged. But if the cute person gazed to one side, the ventral striatum remained dormant, apparently disappointed that the stranger was clearly not interested.
Interestingly, the ventral striatum also perked up if a plug-ugly person gazed to one side, rather than looked at the volunteer right in the eyes.
Origin of the experiment
Romantic novelists like to describe in their writings that two strangers look into each other's eyes across a crowded room and feel the tingle of desire in a special ____71____.
__72__ of the experiment
Investigate whether eye-to-eye contact ____73____ a burst of activity in the reward center of the brain.
 
Procedure of the experiment
◆Ask ____74____ volunteers(8 female and 8 male)to look at photos of the faces of 40 different people who were either looking at the camera or gazing to one side.
◆____75____ blood flows to the various parts of the volunteers’ brain and thus provides a "map" of cerebral activity.
◆Ask the volunteers to rate the attractiveness of all ____76____,
◆____77____ their score against the scan.
 
____78____ of the experiment
◆As long as the eyes meet ____79____, there must be activities in the brain area. On the other hand, there is no activity at all.
◆The activity of the brain is also ___80_____ with the people’s appearance closely.

D
The recent, apparently successful, prediction by mathematical models of an appearance of El Nino—the warm ocean How that periodically develops along the Pacific coast of South America has excited researchers.Jacob Bjerknes pointed out years ago how winds might create either abnormally warm or abnormally cold water in the eastern equatorial (赤道附近的) Pacific.Nevertheless, before the creation of the models, no one could explain why conditions should regularly change between appearances of the warm El Nino and the so-called anti-El Nino.The answer, at least if the current model that links the behavior of the ocean to that of the atmosphere is correct, is to be found in the ocean.
It has long been known that during an El Nino, two conditions exist: unusually warm water extends along the eastern Pacific and winds blow from the west into the warmer air rising over the warm water in the east.The contribution of the model is to show that the winds of an El Nino, which raise sea level in the east, send a signal to the west lowering sea level at the same time.According to the model, that signal is created as a negative (負(fù)的) Rossby wave, a wave of lower sea level, that moves westward parallel to the equator at 25 to 85 kilometers per day.Taking months to move across the Pacific, Rossby waves march to the western boundary of the Pacific basin, which is modeled as a smootli wall but in reality consists of quite irregular island chains.
When the waves meet the western boundary, they are reflected, and the model predicts that Rossby waves will be broken into many coastal Kelvin waves carrying the same negative sea-level signal.These eventually shoot toward the equator, and then head eastward along the equator drove by the earth at a.speed of about.250 kilometers per day.When enough Kelvin waves of adequate amplitude (振幅) arrive from the western Pacific, their negative sea-level signal overcomes the feedback mechanism, raising the sea level, and they begin to drive the system into the opposite cold mode.This produces a gradual change in winds, one that will eventually send positive sea-level Rossby waves westward, waves that will eventually return as cold cycle—ending positive Kelvin waves beginning another warming cycle.
67.What is the passage mainly about?
A.How Rossby waves are found.
B.Where El Nino is formed.
C.What the models predict.
D.How the models work.
68.Where does El Nino often appear?
A.Along the western coast of the USA .
B.In the Pacific in the south, of the equator.
C.In the Pacific in the north of the equator.
D.Along the southern coast of South America.
69.What is right according to the passage?
A.Rossby waves and Kelvin waves move in opposite directions along the equator.
B.People could explain El Nino before the creation of the mathematical models.
C.Adequate sea-level waves can produce westward positive cold cycle.
D.The speed of Rossby waves is faster than that of Kelvin waves.
70.What does the underlined word "waves" in Paragraph 3 refer to?
A.Kelvin waves.       B.Sea-level signals.   C.Coastal waves.   D.Rossby waves.

It doesn't take a rocket scientist long time to figure out that there are better things you could do for your health than take deep breaths on a smoggy(煙霧的)day. A growing pile of research suggests that even relatively low levels of air pollution may be more harmful than previously realized, to both heart and lungs(肺). The latest articles from researchers, published this week in the New England Journal of Medicine, focuses on how particulate (微粒) matter from air pollution affects lung function.
“The effect of low levels of particulate pollution found in many urban areas is not unlike secondhand smoke,” experts say. Studies show that short-term effects from particulates include diminished(減少) lung function, coughing, wheezing, and heart attacks. Long-term exposure can also slow normal lung growth, damage lung airways, and increase the risk of dying from lung cancer.
Certain populations, such as the very old and the very young, are the most vulnerable to air pollution. However, even the most alarming studies conducted in the most polluted areas suggest that the average person's individual risk from exposure (暴露) is very slight. Relative risk numbers often seem more frightening than they actually are. For example, an earlier study published in the New England Journal of Medicine found that short-term exposure to traffic fumes tripled ( 成為3倍) the risk of heart attacks in heart-attack survivors.
Short of moving to the countryside or at least away from busy roads, shielding yourself from the effects of air pollution is not easy. Masks won't work. “At the very least,” suggests Murray Mittleman, a cardiologist at Harvard University, “people who regularly exercise outdoors near highways may want to consider remapping their route.”
66. What does the underlined sentence in the first paragraph mean?
A. Rocket scientists are making researches on people’s health.
B. It's obvious that air pollution has a bad effect on people’s health.
C. People aren't sure whether taking deep breaths on a smoggy day is bad.
D. People often have a hard time when taking deep breaths on a smoggy day.
67. The word "vulnerable" in Paragraph 3 probably means _________.
A. easy to be hurt            B. easy to be protected
C. easy to be used            D. easy to be saved
68. The main idea of Paragraph 3  is _________.
A. that even small risk from particulate causes big problems
B. that air pollution often leads to heart attack
C. who are most likely to get affected
D. that we shouldn't worry about the average low risk
69. In order to be healthier, you'd better _________.
A. take deep breaths         B. wear a mask   
C. live in a countryside       D. clean the busy road
70. The passage is written in a(n) _________ tone.
A. subjective         B. humorous     C. doubtful      D. objective

B
A mosquito is an insect that is found all over the world.There are thousands of different kinds of mosquitoes in many different sizes and colors.The female mosquito needs blood from vertebrates (脊椎動物)to lay eggs and produce more mosquitoes.She has a special part of her mouth that she uses to suck blood,and her saliva(spit)thins the blood so she can drink it.In fact.It’s the mosquito’s saliva that makes the bites itch(癢)!
A person who gets bitten by a mosquito will notice a wheal,which is a bump around the bite.
The wheal will be round,with pink or red around the edge and white in the middle.The wheal will
itch a lot.Soon the wheal will disappear, but the itch will stay.
If you’ve been bitten by a mosquito,wash the bite with soap and water.Put on some calamine lotion to help stop the itching,or an adult can find an anti-itch cream at the drugstore for you.Placing an ice pack on the bite may also help.Tell an adult you’ve been bitten by a mosquito,especially if you live in the eastern United States.But if you develop an allergic reaction and feel dizzy or sick,tell a doctor immediately.He can treat allergic reactions with sole medicine.
The best way to avoid mosquito bites is to wear an insect repellent.Repellents that include one of these ingredients are best:BEET and lemon eucalyptus.Ask a parent to help you apply them.
Since mosquitoes lay their eggs in water,it’s also a good idea to empty out buckets,flower pots,toys and other things in your yard that may have collected water during a rainstorm.And when it’s possible,you’d better wear long-sleeved shirts and long pants to keep mosquitoes away from your skin.
60.What makes you itch after the mosquitoes’bites?
A.A bump around the bite.          B.The mosquito’s saliva.
C.Some calamine lotion.             D.An antic-itch cream.
61.The underlined word“wheal”(Paragraph 2)is closest in meaning to________.
A.a(chǎn) small mouth that can prevent an insect
B.a(chǎn) small mark after an insect bite that usually itches
C.a(chǎn)n illness after an insect bite that always spreads nearby   
D.a(chǎn)n illness from mosquitoes’ bites and other pollution diseases
62.Which of the following is TRUE according to this passage?
A.There are thousands of mosquitoes in the same sizes and colors.
B.The wheal will never disappear forever but the itch will disappear soon.
C.Ask a doctor for some medicine if you develop an allergic reaction for the bite.
D.Ask a parent for an insect repellent if you see mosquitoes laying their eggs in water.

C
Zanzibar,Tanzania--Hundreds of dead dolphins were washed up on Friday along the shore of a popular tourist place on Tanzania’s northern coast.Scientists have ruled out poisoning.
It was not immediately clear what killed the 400 dolphins,whose dead bodies lied along a 4-kilometer coast of Nungwi,said Narriman Jidawi,a marine biologist at the Institute of Marine Science in Zanzibar.But the bottleneck dolphins,which live in deep offshore waters,had empty stomachs,meaning they could have got lost and had been swimming for some time to reorient themselves.They did not die of hunger and were not poisoned,Jidawi said.
In the US,experts were looking into the possibility that sonar(聲吶)from the US submarine could have caused a similar incident in Marothon,F(xiàn)lorida,where 68 deep-water dolphins stranded(擱淺)themselves in March 2005.
The deaths are a blow to the tourism industry in Zanzibar,where thousands of visitors go to watch and swim with dolphins.Villagers,fishermen and hotel residents found the dead bodies and told officials.Mussa Aboud,Zanzibar’s director of fisheries,went on state radio to warn the public against eating the dolphins’meat,saying the cause of death had not been found.
The Indo-Pacific bottlenose,commonly known as dolphins,are the most common species in Zanzibar’s coastal waters,with bottlenose and humpback dolphins often found in mixed-species groups.
63.According to the passage,the bottleneck dolphins            
A.a(chǎn)re often attacked by submarine in deep water
B.find it hard to find enough food near the coast
C.often fall ill along the shore of a tourist place
D.1ike living in the deep waters near the coast
64.The underlined word“reorient”means           
A.lose their way                   B.find their way
C.look for food                        D.fight against enemies
65.What can we infer from the passage?
A.The dolphins died because of the sonar from US submarines.
B.The dead dolphins can not be eaten as they are poisonous.
C.The US experts are researching sonar at present.
D.The ability of locating is extremely important for dolphins.
66.What would be the best title for the passage?
A.400 dolphins died along the coast of Nungwi.
B.Dolphins are facing increased risk of death.
C.It’s necessary for us to protect dolphins.
D.Nungwi is famous for many dolphins there.
