Why is pink or purple a color for girls and blue or brown for boys?
The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils.
People’s choice of colors is also influenced by their bodies' reactions toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomach aches.
Red can cause a person’s blood pressure to rise and increase people’s appetites(食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person’s eye.
Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.
The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.Muslims regard green as a symbol of heaven mainly because of their .

Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming. Countless recent reports from the world’s leading scientific bodies have said the same thing. For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity.”
The idea that humans could change the planet’s climate may be counter-intuitive, but the basic science is well understood. Each year, human activity causes billions of tons of greenhouse gases to be released into the atmosphere. As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.
Of course, the planet’s climate has always been changing thanks to “natural” factors such as changes in solar or volcanic activity, or cycles relating the Earth’s going around the sun. According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question. As Robert Henson puts it in The Rough Guide to Climate Change, “If some newly discovered factor can account for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths –one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty. In most scientists’ opinion, the global warming is mainly caused by ________.
A.solar activity |
B.volcanic activity |
C.the Earth’s going around the sun |
D.human activity |

London has become a cycle friendly zone after the launch of a new bike hire scheme.It has been designed to encourage more people to cycle in and around central London.
So how does it work?First you have to sign up to the scheme to be sent a key.The key will unlock one of the bikes,which are kept at docking stations in and around central London.You have to pay an access fee for the key and then you pay as you go,for the length of time you use the bike.
Transport for London, which runs the scheme,are hoping to have 6,000 bikes and 400 docking stations in place by the end of the year.The new hire system is hoping to ease congestion in London and is expected to generate up to 40,000 extra cycle trips a day into the city centre. London Mayor Boris Johnston launched the scheme and said London had been “filled with thousands of gleaming machines that will transform the look and feel of our streets and become as common place on our roads as black cabs and red buses”.
However,there have been a few problems since the scheme was launched last Friday.On the first day some people found they couldn’t dock their bike properly and their usage of the bike had not registered.Transport for London did admit they had been expecting a few “teething problems” and have said they wouldn’t charge for the first day as a“gesture of goodwill”.Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.
Despite the comments,the green-thinking London Mayor still seems very positive about things,saying,“My campaign for the capital to become the greatest big cycling city in the world has taken a gigantic pedal-powered push forwards.”Which is the correct order of a bike hire?
a.pay a usage charge according to the time b.pay for the key
c.cycle in and around central London d.sign up as a member to get a key
A.b-d-c-a | B.b-c-a-d | C.d-c-b-a | D.d-b-c-a |
.Which of the following is NOT the “teething problems” of the scheme?
A.People were unable to lock properly. |
B.People could not dock the bikes properly. |
C.People had no enthusiasm about the scheme. |
D.It’s too expensive for some people to hire a bike. |
.From the passage we know __________.

C.all the citizens in London are in favor of the scheme |
D.the London Mayor has great confidence in the scheme |
Global warming is causing more than 300,000 deaths and about $125 billion in economic losses each year, according to a report by the Global Humanitarian Forum, an organization led by Annan, the former United Nations secretary general.
The report, to be released Friday, analyzed data and existing studies of health, disaster, population and economic trends. It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition (营养不良) and heat-related health problems.
But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions.
Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries, were being seriously affected by climate change. It projected that the number would double by 2030.
Roger Pielke Jr., a political scientist at the University of Colorado, Boulder, who studies disaster trends, said the Forum’s report was “a methodological embarrassment” because there was no way to distinguish deaths or economic losses related to human-driven global warming amid the much larger losses resulting from the growth in populations and economic development in vulnerable (易受伤害的) regions. Dr. Pielke said that “climate change is an important problem requiring our utmost (极度的) attention.” But the report, he said, “will harm the cause for action on both climate change and disasters because it is so deeply flawed (有瑕疵的).”
However, Soren Andreasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.
In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability(弱点) to climate hazards(危害)while still curbing (限制) the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report.What is the finding of the Global Humanitarian Forum?
A.Global temperatures affect the rate of economic development. |
B.Rates of death from illnesses have risen due to global warming. |
C.Malnutrition has caused serious health problems in poor countries. |
D.Economic trends have to do with population and natural disasters. |

A.It was challenged by some climate and risk experts. |
B.It aroused a lot of interest in the scientific circles. |
C.It was warmly received by environmentalists. |
D.It caused a big stir in developing countries. |
What does Dr. Pielke say about the Forum’s report?
A.Its statistics look embarrassing. |
B.It is invalid in terms of methodology. |
C.It deserves our closest attention. |
D.Its conclusion is purposely exaggerated. |
What is Soren Andreasen’s view of the report?
A.Its conclusions are based on carefully collected data. |
B.It is vulnerable to criticism if the statistics are closely examined. |
C.It will give rise to heated discussions at the Copenhagen conference. |
D.Its rough estimates are meant to draw the attention of world leaders. |
What does Kofi Annan say should be the focus of the Copenhagen conference?
A.How rich and poor regions can share responsibility in curbing global warming. |
B.How human and economic losses from climate change can be reduced. |
C.How emissions of heat-trapping gases can be reduced on a global scale. |
D.How rich countries can better help poor regions reduce climate hazards. |
You never see him, but they’re with you every time you fly. They record where you are going, how fast you’re traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They’re known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device’s homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots’ conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft’s final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand(抵挡)massive force and temperatures up to 2,000℉. When submerged(潜入水中), they’re also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they’re still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane’s black boxes were never recovered.What does the author say about the black box?
A.It ensures the normal functioning of an airplane. |
B.The idea for its design comes from a comic book. |
C.Its ability to ward off disasters is incredible. |
D.It is an indispensable device on an airplane. |

A.New materials became available by that time. |
B.Too much space was needed for its installation. |
C.The early models often got damaged in the crash. |
D.The early models didn’t provide the needed data. |

A.There is still a good chance of their being recovered. |
B.There is an urgent need for them to be reconstructed. |
