NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever.
The project to build a base on the moon will begin soon after 2020, with astronauts living there within four years.
The project comes after several excellent scientists and environmentalists asked humans to look beyond Earth to ensure the survival of the species (物種).
Eventually, the moon will be a base for humans to explore the solar system and one day land on Mars.
NASA began planning for the first moon landing since 1972 when George Bush, the US president, announced his new plan for space exploration four years ago.
NASA has already talked about the design of the Orion spacecraft that will replace the old space shuttle fleet in 2010.
The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years.
Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power. Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.
小題1:When was the plan to explore space first announced according to the passage?
A．In 1972.B．In 1950.C．In 1968.D．In 2020.
小題2:The reasons why NASA has begun the plan to explore space include the followings except ________.
A．to protect EarthB．to explore deep space
C．to finish Mars missionD．to show how powerful the USA is
小題3:In the future, when people fly to the moon, they will probably not bring with them too much ________
A．hydrogen B．foodC．oxygenD．water
小題4:The passage mainly talks about ________.
A．the USA’s new plan for space exploration
B．how to build a base on the moon
C．why to ensure the survival of the species
D．where to get new natural resources

小題1:C
小題2:D
小題3:D
小題4:A

Last night’s meteor (流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothschild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.
“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment.”
Astronomers—scientists who study stars and planets—have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.
There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats, frogs, snakes, etc. For example, outdoor lighting severely affects migrating (遷徙的) birds. According to the International Dark-Sky Association, “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”
Countless more animal casualties (傷亡) result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings. But some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase a person’s chances of getting cancer.
Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.
小題1:It happened last night that _____.
A．the city’s lights affected the meteor watching
B．the meteors flew past before being noticed
C．the city light show attracted many people
D．the meteor watching ended up a social outing
小題2:What do the astronomers complain about?
A．Meteor showers occur less often than before.
B．Their observation equipment is in poor repair.
C．Light pollution has remained unsolved for years.
D．Their eyesight is failing due to artificial lighting.
小題3:What is the author concerned about according to Paragraph 4?
A．Birds may take other migration paths.
B．Animals’ living habits may change suddenly
C．Varieties of animals will become sharply reduced
D．Animals’ survival is threatened by outdoor lighting.
小題4:Lighting regulations in Flagstaff, Arizona are put into effect to _____.
A．lessen the chance of getting cancer
B．create an ideal observation condition
C．ensure citizens a good sleep at night
D．enable all creatures to live in harmony
小題5:What message does the author most want to give us?
A．Saving wildlife is saving ourselves.
B．Great efforts should be made to save energy.
C．Human activities should be environmentally friendly.
D．New equipment should be introduced for space study..

The oldest and most common source(來源) of renewaBle energy known to man, Biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of Biomass materials is everywhere ---- from trees and grasses to agricultural and city ---- life wastes ----Biomass promises to play a continuing role in providing power and heat for millions of people around the world.
According to the Union of Concerned Scientists(UCS), Biomass is a kind of renewaBle energy source that produces no carBon dioxide(二氧化碳), Because the energy it contains comes from the sun. When plant matter is Burned, it gives off the sun’s energy. In this way, Biomass serves as a sort of natural Battery(電池) for storing the sun’s energy. As long as Biomass is produced continuously ----with only as much grown as is used--- the “Battery” lasts forever.
According to the Energy Information Administration, Biomass has Been one of the leading renewaBle energy sources in the United States for several years running through 2007, making up Between 0.5 and 0.9 percent of the nation’s total electricity supply. In 2008----although the numBers aren’t all in yet----wind power proBaBly took over first place Because of the rapid development of wind farms across the country.
Producing power from Biomass helps reduce some 11 million tons of carBon dioxide each year. Some homeowners also try to make their own heat By using Biomass materials. Such practice may save homeowner’s money, But it also produces a lot of pollution. So, the Best way is to encourage power plants to use it.
小題1:Why is Biomass considered as “ a sort of natural Battery”?
A．It Burns merely plant matter.B．It keeps producing electricity.
C．It stores the energy from the sun.D．It produces zero carBon dioxide.
小題2:We learn from the text that in 2008 ______.
A．Wind power would Be the leader of renewaBle energy.
B．there was a rapid growth of electricity production
C．Biomass might Become the main energy source
D．0.5~0.9 of power supply came from Biomass
小題3:Why does the author encourage power plants to use Biomass?
A．To prevent the waste of energy.B．To increase production safety.
C．To reduce pollution.D．To save money.
小題4:Where does the text proBaBly come from?
A．A research plan.B．A science magazine
C．A Book review.D．A Business report.

Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington, D.C.
And on Tuesday, August 23rd, witnesses say she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she’s not the only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelter.
“It’s very different from their normal call,” said Brandie Smith, the zookeeper. “The lemurs (monkey-like animals of Madagascar) will sound an alarm call if they see or hear something highly unusual.”
But you can’t see or hear an earthquake 15 minutes before it happens, can you? Maybe you can — if you’re an animal. “Animals can hear above and below our range of hearing,” said Brandie Smith. “That’s part of their special abilities. They’re more sensitive to the environment, which is how they survive.”
Primates weren’t the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of bird) gathered before the quake and stayed together until the shaking stopped.
So what kind of vibrations were the animals picking up in the moments before the quake? Scientist Susan Hough says earthquakes produce two types of waves — a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She said she thinks the “P” wave might be what set the animals off.
Not all the animals behaved unusually before the quake. For example, Smith says the zoo’s giant pandas didn’t jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I’m not surprised at all,” Smith said.
小題1:Why did Mandara act strangely one day?
A．Because it sensed something unusual would happen.
B．Because its daughter Kibibi was injured.
C．Because it heard an orangutan let out a loud call.
D．Because an earthquake had happened.
小題2:According to Brandie Smith, _____.
A．many animals’ hearing is sharp
B．earthquakes produce two types of waves
C．primates usually gather together before a quake
D．humans can also develop the ability to sense a quake
小題3:Which word in the passage has a close meaning to the underlined word “cover”?
A．vibrationB．shelterC．quakeD．range
小題4:Which animal seems unable to sense a quake?
A．A giant panda.B．A flamingo. C．A lemur.D．A lizard.
小題5:What is the best title for the passage?
A．How animals survive a quake. B．How animals differ from humans.
C．How animals behave before a quake.D．How animals protect their young in a quake.

Squirrels often communicate with whistles, chirps and chucks, which sound like the word “chuck”． Whistles and chirps are like the sounds that many birds make．Now scientists have translated some of their squirrel-speak．
Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls．The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍）their reponses．Some squirrels lifted their heads up and became．Alert(警惕的）．Creatures that were more frightened simply ran for their lives and dived into caves．
"In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger．' " Hare told．Discovery News．
Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems．
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too．According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms．
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害獸）. Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.
小題1:The text mainly talks about
A．the study on the language of squirrels
B．the comparison between squirrels and chickadees
C．the calling for the protection of squirrels
D．the ways for squirrels to escape from their enemies
小題2:If a squirrel is in a very dangerous situation, it would probably make ____．
A．whistles with chucksB．pure chirps
C．whistles without chucksD．repeated chucks
小題3:The underlined word “tidings” in pardgmph 6 probably means ____．
A．difficultiesB．poisesC．messagesD．languages
小題4:What can be learned from this text?
A．Squirrels communicate with cach other as humans do.
B．Some squirrels understand the recorded alarm calls.
C．Other animals also well understand the language of squirrels．
D．Birds such as chickadees don’t have their own language．
