Rapidly warming climate is likely to seriously change crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave half the world's population facing serious food shortages, according to a study to be published on Friday in Science Magazine．
The population of this equatorial(赤道的)belt is among the poorest on Earth and is growing faster than anywhere else, the study said．
''The stresses on global food production from temperature alone are going to be huge, and that doesn't take into account water supplies stressed by the higher temperatures,” David Battisti, lead author of the study, said．
Battisti, a professor at the University of Washington, cooperated with Rosamond Naylor, director of Stanford University's Program on Food Security and the Environment, to examine the influence of climate change on the world's food security．
By combining direct observations with data from 23 global climate models that contributed to a Nobel Prize－winning research in 2007, Battisti and Naylor determined that there is greater than a 90 percent probability that by 2100 the lowest growing-season temperatures in the tropics and subtropics will be higher than any temperatures recorded there to date．
In the tropics, the higher temperatures can be expected to cut yields of the primary food crops, maize(玉米)and rice by 20 to 40 percent, the researchers said．
The serious climate issues will not be limited to the tropics, the scientists conclude．As an example, they cite record temperatures that struck Western Europe in June, July and August of 2003．The summer-long heat wave in France and Italy cut wheat yields and fodder(饲料)production by one-third．

His teacher thought he was dumb(愚笨的)．Talent spotters(星探)thought he was ugly．But Jay Chou, 24, is now one of Asia’s hottest pop stars．
Last week he had the honour of being the first Asian male singer to make the cover of Time, a popular magazine based in the US．He has won more than 30 entertainment awards over the past two years．
Chou released(发行)his first album Jay in November 2000,and with two follow up albums－Fantasy and Eight Dimensions－ his music has come to rule the Asian pop world．
The entertainment industry has nicknamed him “a small heavenly king”．But Chou says, he is not a king, at least he wasn’t before he shot to stardom．As a boy, he was called “stupid”．His high school English teacher said young Chou had a learning disability．“He had very few facial expressions(面部表情)．I thought he was dumb．”
Chou did poorly at maths, science and English．But his mother noticed the quiet, shy boy was sensitive to music：when he heard western pop music, he seemed to vibrate(摇摆)．So she took Chou to a piano school at four years old．He practiced all the time, focusing on the keys the way other children focus on ice-cream．At the end of the high school, he failed his exams and didn’t go to university．
In a show he was seen playing the piano by a major Taiwanese entertainer, Jacky Wu．The 18-year-old Chou became a contract(签约)song writer for Wu’s music studio．There he spent one and a half years writing songs for famed artists such as a Valen Hsu and Coco Lee．
He proved that he could be more than a songwriter．His catchy tunes have mainstreamed(成为主流)rap and R&B in the Mando-pop world(华语音乐)．And his success proves that the music still matters more than looks and image．

Every five minutes my children ask me for the “latest thing”．They tell me that all their friends have it already and they can’t live without it．Our house is full of Games Boys, Play Station CDs and a million other “latest things”．
But, the one “latest thing” we have refused to buy is a mobile phone．Our twelve-year-old son wants one, and we’ve said “no”．He says he’ll only use it for texting and he really needs it for emergencies．
We don’t want him to have a mobile phone, because it may be bad for children’s health．Unfortunately, when I say, “ As your father, I don't want you to have a mobile phone, because you might get a brain tumour(肿瘤), ” he tells me that he doesn’t mind．
Why do twelve-year-old boys only want things that are bad for them? We’ve already told him that he can’t listen to rap music－the words are disgusting(使人反感的)．And I’ve said no to beer with his meals．Right now, I’m saying no to everything．
Then a few weeks ago he asked for something called a BB gun．He says everybody’s got one．Of course they have．He shows me a website full of them and tells me it only fires plastic pellets(小子弹)．Finally, I say yes．I can’t believe I’ve said no to phones and yes to guns．
In October, our son becomes a teenager, and I pray that research will find that mobile phones are safe…even better, that young people may become less moody－and more interested in personal hygiene(卫生)．
Until then, I’m saying no．(281words)

If you are above the age of 40 then there are chances you would not know much about Snap Music．But if that is the case, then ask your daughter or son, and perhaps, they’d even perform it for you．Indeed, Snap Music is one of the cool hip hop rap styles that support hip hop music．In simple words, Snap Music is the music to which you “snap(捻着手指发劈啪声)your fingers and move with the rhythm．This may seem relatively easy, but sure enough, it has its share of uniqueness which makes it stand apart．
The theoretical and technical characteristics of Snap Music are slow-paced beats, regular and timed snapping of fingers, which created pleasing rhythms．Often as rappers rap, they get the audience clapping or snapping along with them．
Snap Music was from Atlanta．It gradually made its way to the other parts of America．It is generally believed that Snap was inspired by Crunk Music and it is Atlanta’s Crunk style．But they are quite different．While Crunk has high energy, Snap has an unhurried feel to it．An occasional whistle or a polyrhythmic(多节奏的)combination can he heard; this is done to improve the feeling of the music．It is also said that the music was made for the club-crowd and at first was meant for dance lovers; but as the form developed, it turned out to be rather slow．
There is a wide audience for this type of music．Here, this type of hip hop music is often simple with not much depth or story．But then again, how many rap songs have depths and story these days? So, if you are a teenager or a young adult, you might just enjoy the change that Snap offers．
