    　　Scientists have long understood the key role that oceans play in regulating the Earth's climate．Oceans cover 70 percent of the globe and store a thousand times more heat than the atmosphere does．What's newer is the understanding of how this key component(组成)of our climate system responds to global warming．

    A brake on global warming－for now

    　　One of the ocean's most important climate functions is absorbing heat and carbon dioxide(CO2), one of the gases that cause global warming．Acting as a heat sponge(海绵), the oceans have absorbed huge amounts of heat and CO2 in the last forty years．

    　　Fujita explains that “the oceans are saving us from faster climate change－they are a big flywheel that delays rapid overheating of the earth, putting a brake on the climate system．”

    　　“That's the good news,” he adds．“The bad news is that the oceans only slow the atmospheric warming．Once the oceans come to balance with a greenhouse-gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter．” But where and how the oceans release this accumulated(积累)heat is uncertain．And as the ocean stores heat, fragile(脆弱的)underwater ecosystems are struggling．

    　　The most recent scientific report from the Intergovernmental Panel on Climate Change(IPCC)also　notes with concern that the ocean is acidifying(酸化)because of increased absorption of atmospheric CO2, and thus causing a threat for shell-forming species．Sharp increases in carbon dioxide levels will cause further acidification of the ocean．

    Currents distributing heat

    　　Another important role the oceans play is that of distributor．Oceans deliver heat and life-sustaining nutrients around the globe．Just as blood vessels bring oxygen and nutrients to cells in the human body, the ocean's currents carry oxygen, nutrients and heat throughout the Earth．The ocean distributes 25 to 50 percent of the energy the planet receives from the sun．For example, the Gulf Stream carries heat across the Atlantic．This warm current gives northwestern Europe a milder climate than it would normally have so far north．A change to the ocean's circulation(循环)patterns could throw Europe into a colder period, even as the rest of world experiences warmer temperatures．

    (1)

    We can infer from the passage that ________．

    [　　]

    A．

    the oceans cause global warming

    B．

    the oceans stop global warming

    C．

    the oceans release nutrients and heat

    D．

    the ocean ecosystems face more dangers

    (2)

    From the passage we can learn that the ocean's currents ________．

    [　　]

    A．

    produce oxygen and nutrients everywhere

    B．

    absorb 25～50％of the energy from the sun

    C．

    distribute heat and nutrients around

    D．

    change the ocean's circulation patterns

    (3)

    Which of the following is NOT the result of the ocean absorbing heat and carbon dioxide?

    [　　]

    A．

    It causes further acidification．

    B．

    It affects shell-forming species．

    C．

    It makes the atmosphere hotter．

    D．

    It regulates the Earth's climate．

    (4)

    This passage mainly talks about ________．

    [　　]

    A．

    the roles of oceans

    B．

    global warming

    C．

    阅读理解

    　　Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money．To win, they had to finish the 142-mile race in less than 10 hours．Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part－drivers．

    　　DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields．But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance．One had its brake lock up in the starting area．Another began by throwing itself onto a wall．Another got tied up by bushes near the road after 1.9 miles．

    　　One turned upside down．One took off in entirely the wrong direction and had to be disabled by remote(远距离的)control．One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock．The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire．

    　　“You get a lot of respect for natural abilities of the living things, ” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics．“Even ants(蚂蚁)can do all these tasks effortlessly．It’s very hard for us to put these abilities into our machines．”

    　　The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately．Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good．She is more advanced, even months old, than any machine humans have designed．

    (1)

    Watchers doubted if any of the vehicles could finish the race because ________．

    [　　]

    A．

    they did not have any human guidance

    B．

    the road was not familiar to the drivers

    C．

    the distance was too long for the vehicles

    D．

    the prize money was unattractive to the drivers

    (2)

    DARPA organized the race in order to ________．

    [　　]

    A．

    raise money for producing more robotic vehicles

    B．

    push the development of vehicle industry

    C．

    train more people to drive in the desert

    D．

    improve the vehicles for future wars

    (3)

    From the passage we know “robotic vehicles” are a kind of machines that ________．

    [　　]

    A．

    can do effortlessly whatever tasks living things can

    B．

    can take part in a race across 142 miles with a time limit

    C．

    can show off their ability to turn themselves upside down

    D．

    can move from place to place without being driven by human beings

    (4)

    [　　]

    A．

    about eight miles

    B．

    six miles

    C．

    almost two miles

    D．

    about one mile

    (5)

    In the last paragraph, the writer implies that there is a long way to go ________．

    [　　]

    A．

    for a robotic vehicle to finish a 142-mile race without any difficulties

    B．

    for a little child who has just learned to walk to reach the cookie on the table

    C．

    for a robotic vehicle to deal with a simple problem that a little child can solve

    D．

    　　Phone producers show us every year some really superb concept phones and even if 99％ of those phones never see the production line, they give us a small glimpse(一瞥)of what the phones will look like in the near future．We’ve made a list of what we think are the coolest concept phones presented in 2010．This is not a top, so the order is random(随机的)．Oh, and one more thing, remember, these are concept phones, which means they are not in production and are not for sale, so please don’t ask us where you can get them and what the prices are．

    　　1．LG Flutter Concept Smart-phone

    　　The LG Flutter has a face like the iPhone．The only difference is that the LG Flutter looks more like a fan or a killer’s tool which we see in sci-fi movies．

    　　4．Nokia Morph

    　　The Nokia Morph is created by Finnish company Nokia．The concept was the product of a joint study by the Nokia Research Center and the University of Cambridge’s Nanoscience Center．

    　　The phone could be bent into numerous shapes, so it can be worn around the wrist(手腕)or held up to the face．The transparent(透明)phone would allow it to be see-through yet functional．It has a self-cleaning surface that can absorb solar energy to recharge the phone battery(电池)．

    　　5．Clover Phone
