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.

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．”

My mother is a geneticist, and from her I learned that despite our differences in size, shape and color, we humans are 99.9 percent the same. It is in our 36 to see differences: skin, hair and eye color, height, language. But also in our nature, way down in the DNA that 37 us human, we are almost the 38 .
I believe there is more that unites us than 39 us.
My mother came to the US from India. She is 40 enough that she got her service 41 in a diner in 1960s Dallas. My father is a white boy from Indiana whose 42 came from Germany in the mid-1800s.
It seems 43 to admit now, but I never 44 that my parents were different colors. One day, I watched my parents walk 45 the street of our church together. They were 46 in the service that day, and as they walked, I saw their hands 47 together in unison(一致地). I noticed for the first time how dark my mother was, and how white my father was. I knew them as my parents 48 I realized their skin color. I'm sorry to say that now when I see a mixed-race 49 walking down the street, I see the "mixed race" first and the "couple" second.
When my parents married in 1966, there were 50 places in this country that had laws 51 mixed marriage. 52 , my white grandfather, 53 father had been a typical racist, was not against their marriage.
Some of us are men, some are women. Some are young, some old. Some of us are short and others 54 . Some right-handed, some left-handed. We have lots of differences; we are all 55 . But deep down inside us, down in our DNA, we are 99.9 percent the same. And I believe we need to remember that.

In modern society, competition is everywhere. No wonder a English philosopher considers competition the source of a series of problem such as frustration and anxiety. Therefore, if we stress cooperation too much, there would be no progress. In my opinion, all are important and necessary.
Let's take the competition at school for example. Even a gifted student won't make a remarkable progress if he is in a class without competition. That's because competition, and rather, challenge is a driving force made him go forward. On the other hand, if we don't cooperate with each other, it's impossible for us learn from each other. And that's why most of the great discoveries or inventions in the modern world are the result of cooperation.
To conclude, those who laugh last are the people who can successful cope with the relationship between competition and cooperation.
