放下手机!多玩手机会影响心情

Checking your mobile phone while having a drink with friends or taking a call over dinner, isn't just annoying for those around you - it could be making you unhappy.

和朋友吃饭或喝饮料时玩手机,不仅会让你的朋友感到生气,还会使你不快乐。

A study found that we spend more than a quarter of our leisure time distracted, with everything from barking dogs to road works disturbing concentration.And mobile phones were the worst offenders.

一项研究发现,我们每天三分之一的空闲时间都在开小差,例如狗叫、道路施工等情况都会分散我们的注意力。而手机是最容易让我们分心的物品。

The gadgets not only proved the biggest attention-grabber –they also seemed to affect people's happiness.

研究发现,手机不仅是最容易分散我们注意力的物品,而且还可能影响人们的幸福感。

The University College London researchers are not sure why this is but say it is possible that we feel upset that are unable to control the urge to fiddle with our phone.

伦敦大学学院的研究者们并不清楚为什么会这样。他们猜测,可能是因为无法控制拨弄手机的冲动,所以会使人因此沮丧。

In contrast, we realise we have no control over external distractions like road works and so they affect us less.

相反,我们觉得自己无法控制诸如道路施工等让人分心的情况,所以这些情况对我们影响不大。

Whatever the reason, they said that it is clear that we live in an 'age of distractions'.

但不管怎样,我们的确生活在一个“容易分心的时代”。

The survey of 2,000 people by fashion technology firm Mous, suggests almost half of our biggestirritations are technology-related.

这项研究由莫斯时尚技术公司发起,对2000人进行了调查;结果显示:令人烦恼的事情中,有将近一半都是和科技相关的。

We hope these findings will help highlight how important it is to carve out time where attention is undivided and to enjoy spending quality time together.'

我们希望这些发现能够帮助人们认识到,是时间要专心地享受高质量的生活了。

左撇子影响身心健康?!

Things You Never Knew About Being Left-Handed

关于左撇子你不知道的事

by Amanda MacMillan

——阿曼达麦克米兰

With just 10% of the population being left-handed, it can be easy for everyone else to forget we're living in a right-handed world. But aside from making it tough to cut a straight line with a pair of scissors designed for righties, being a southpaw can also have some subtle effects on our physical and mental health.

由于左撇子在人口中比例仅为10%,所以人们很容易忽略这样一个事实,即自己正生活在一个左撇子的世界。除了能够轻易地将自己同一般人区分开来之外,左撇子的习惯对个人的身体和心理健康还有着微妙的影响。

The brains and bodies of lefties may operate differently than those of right-handed people and in mixed-handed people, who may have different dominant hands for different tasks. "Handedness seems to be determined very early on in fetal development, when a lot of other things about your future are being determined as well," says Ronald Yeo, PhD, professor of psychology at the University of Texas-Austin. Here's a look at some of the most mon facts about being left-handed, and what it might really mean for your health.

习惯用右手的人,其大脑和身体的运转方式可能和左撇子有所不同对双撇子来说,不同任务中他们会习惯用不同的手。“人的许多特点在胎儿时期就已经形成了,偏手性似乎也不例外,”德克萨斯州大学奥斯汀分校的心理学教授、博士罗纳德杨说。下面我们会探讨有关左撇子的一些常识以及左撇子对健康的影响。

It's not just genetics

左撇子不一定都是遗传因素导致的。

Scientists aren't exactly sure why some people are left-handed, but they know that genes are responsible about 25% of the time, says Yeo. Left-handedness does tend to run in families, he says, "but noticeably less than other inherited traits, like height or intelligence."

科学家们并不确定为什么有些人是左撇子,但是他们确信,左撇子的遗传因素占到25%。“左撇子的确会在家族内部遗传,但与体重和智力等其他遗传特性相比,其遗传机率却要小很多。”罗纳德杨教授说。

It's linked to stress in pregnancy

左撇子与怀孕期间的压力有关。

In one British study, the fetuses of super-stressed pregnant women were more likely to touch their faces more with their left hands than their right. This could be the first signs of a left-handed child, say the researchers. Other evidence supports that theory. In one 2008 Swedish study of moms and their 5-year-old children, women who were depressed or stressed during their pregnancies were more likely to have mixed- or left-handed kids. In other studies, babies with low birth weight, or born to older mothers, were more likely to be lefties as well.

英国一项研究显示,压力较大的孕妇生出的孩子更倾向于用左手摸脸。这可能是左撇子在婴幼儿时期的第一个征兆。而其他研究结果也证实了这一结论。2008年,瑞典的一项研究显示,孕期较为压抑或压力较大的妇女,她们的宝宝成为左撇子或双撇子的可能性更大。其他研究还显示,出生时体重较低的婴儿或高龄产妇生产的婴儿成为左撇子的机率更大。

英语科普文章选——2004年十大科学发现

不久前,著名的《科学》杂志评选出2004年最重要的十大科学发现。这些发现中既有人类对神秘宇宙太空的探索,也有对身边熟悉事物的新发现。无论是何种的科学探索和发现,人类求知的愿望和动力永远都在推动社会的发展和进步。

Water and robots on Mars chosen as tops in 2004 by 'Science'

WASHINGTON — The conclusive discovery by a pair of wheeled robots that Mars once had vast pools of water and possibly could have harbored life was chosen by the editors of the journal Science as the most important scientific achievement of 2004.

Scientists announced in March that the Mars once played host to salty seas. This Mars Express image indicates water erosion.

NASA's two Mars rovers(漫游者)Opportunity and Spirit, landed on the Red Planet early in 2004 and have since found clear and conclusive evidence that Mars was drenched with(浸透) water at some time in its history.

The editors of Science, one of the world's leading publishers of peer-reviewed, original research, judged the robotic accomplishment as the top scientific "Breakthrough of the Year."

"Inanimate, wheeled, one-armed boxes roaming another planet have done something no human has ever managed," Science reported in this week's edition. "They have discovered another place in the universe where life could once have existed."

Nine other scientific achievements, including discovery of another species of human, were selected as runners-up, but Science editor-in-chief Donald Kennedy said "there wasn't much doubt about this year's winner."

Opportunity and Spirit found unmistakable proof of Martian water: rippled sediments(沉积物) that were once at the bottom of a shallow sea, and rock that once was so water-soaked that "it had rotted," the journal said.

"Their finds mark a milestone in humankind's search for life elsewhere in the universe," Science said.

Kennedy said one of the most important messages from the remote exploration is "the extraordinary efficiency of these robot missions."

He said it is clear that the National Aeronautics and Space Administration must not abandon its robotic exploration while gearing up for President Bush's program to send humans to the moon and later to Mars.

"To do one at the expense of the other would be a mistake," Kennedy said. "It remains to be demonstrated what a human exploration could do that we can't do now or couldn't do in the next 10 years with robotic technology."

The first runner-up for breakthrough of the year was the discovery on the Indonesian island of Flores of fossils from a species of tiny humans who stood about 3 feet tall and had a brain less than a third the size of modern humans. Yet, the diminutive(小的) hominid(原始人) lived about 18,000 years ago. This suggests that Homo floresiensis shared the Earth with Homo sapiens(人类), or modern people. Science said some described the find as "the biggest discovery in half a century of anthropological research."

Third on Science's list of 2004 breakthroughs was the cloning of human embryos by South Korean researcher Woo San Hwang and his colleagues. The work was not an attempt to genetically duplicate a human. Instead, the researchers hoped to make embryonic stem cells for research purposes. Although many other mammals have been cloned, the work was the first to demonstrate that cloning techniques would work with human cells.

Following are the rest of Science's 2004 selections.

4. U.S. and Austrian scientists created a new form of condensate(冷凝物), an ultracold gas that slips into a quantum state where a group of atoms act as a single superatom. The achievement was notable because it used fermions(费米子), a class of atoms with a nuclear structure that makes it difficult to create a condensate.

5. Scientists discovered that "junk DNA," the base pairs between known genes in the human genetic structure, play an important role. Several research teams have found that DNA between genes helps determine how vigorously and often the genes are activated and shapes the coding for protein production.

6. Astronomers discovered a pair of neutron stars(中子星) locked in orbit of each other and spewing out beams of radiation. Both objects are pulsars(脉冲星), rapidly flickering on and off with pulses of energy. One object is pulsing at the rate of 44 times a second. By studying the radiation, astronomers hope for the first time to learn about the density of matter within a neutron star.

7. Naturalists tracking the fate of wild species worldwide reported bad news. A survey of amphibians(两栖动物) found that of 5,700 known species, about 30% were at risk of extinction. A survey in the United Kingdom found that butterflies, songbirds and native plant species are all losing ground in the battle for species survival.

8. It is one of the most common and universally known substances, but researchers are still learning more about water. Several teams of researchers made new discoveries about how water molecules(分子) bind together and how electrons(电子) and protons(质子) dissolve in water. Some of the findings are questioned and Science noted: "Water still gives researchers much to scratch their heads about."

9. A new form of research and aid is creating "a revolution in public health," said Science. The partnership of public and private organizations worldwide is changing the way drugs are developed, tested and distributed to the poorest nations on Earth, the journal said. Researchers tallied at least 92 public-private partnerships worldwide attacking such diseases as malaria, tuberculosis and HIV.

10. Researchers have developed techniques to identify genes in ocean water or in specimens recovered from deep underground. Thousands of new genes have been found. By sequencing these genes, researchers hope to identify news species and, perhaps, learn how organisms survive in harsh and forbidding locations on Earth.

泰哥,我给你找了几个,必须采纳啊! To Pull up the Seedlings to Help Them Grow “拔苗助长”

Once upon a time, there was an old farmer who planted a plot of rice. After he planted the seedlings, every day he went to the field to watch the seedlings grow. He saw the young shoots break through the soil and grow taller each day, but still, he thought they were growing too slowly. Eventually he got impatient with the young plants and suddenly he hit upon an idea that one by one, he pulled up the young plants by half an inch. The next early morning, the young man couldn’t wait to check his “achievement”, but he was heart-broken to see all the pulled-up young plants dying.

从前,有个农夫,种了稻苗(seedlings)后,便希望能早早收成。每天他到稻田时,都发觉那些稻苗长得非常慢。他等得很不耐烦。想了又想,他终于想到一个“最佳方法”,他将稻苗全都拔高了几分。第二天,一早起身,他迫不及待地去稻田看他的“成果”。 哪知,却看到所有的稻苗都枯萎了。

Plugging One’s Ears While Stealing a Bell “掩耳盗铃”

Once upon a time, there was a man who wanted to steal his neighbor’s doorbell. However, he knew clearly that the bell would ring and catch the other people’s attention as long as he touched the bell. So he thought hard and suddenly hit on a clever “idea”. He plugged his ears with something, thinking that everything would go well when he stole the bell. Unfortunately to his disappointment, the bell still rang loudly and he was caught on the spot as a thief.

从前,有一个人想偷邻居门上的铃,但是他知道一碰到铃,铃就会响起来,被人发现。他想啊想,终于他想出一个“妙极”,他把自己的耳朵用东西塞起来,就听不见铃声了。但是当他去偷铃时,铃声仍旧响起来,他被别人当场抓住

The Fox and the Crow “狐狸和乌鸦”

One day a crow stood on a branch near his nest and felt very happy with the meat in his mouth. At that time, a fox saw the crow with the meat, so he swallowed and eagerly thought of a plan to get the meat. However, whatever the fox said to the crow, the crow just kept silent. Until the fox thought highly of the crow’s beautiful voice, the crow felt flattered and opened his mouth to sing. As soon as the meat fell down to the ground, the fox took the meat and went into his hole.

有一天,一只乌鸦站在窝旁的树枝上嘴里叼着一片肉,心里非常高兴。这时候,一只狐狸看见了乌鸦,馋得直流口水,非常想得到那片肉。但是,无论狐狸说什么,乌鸦就是不理睬狐狸。最后,狐狸赞美乌鸦的嗓音最优美,并要求乌鸦唱几句让他欣赏欣赏。乌鸦听了狐狸赞美的话,得意极了,就唱起歌来。没想到,肉一掉下来,狐狸就叼起肉,钻回了洞

Draw a Snake and Add Feet to It “画蛇添足”

Long long ago, several people had a jar of wine among them and all of them wanted to drink it by himself. So they set a rule that every one would draw a snake on the ground and the man who finished first would have the wine. One man finished his snake very soon and he was about to drink the wine when he saw the others were still busy drawing, so he decided to draw the feet to the snake. However, before he could finish the feet, another man finished and grabbed the jar from him, saying, "Who has ever seen a snake with feet?” The story of "Draw a snake and add feet to It.” tells us going too far is as bad as not going far enough.

古时几个人分一壶酒。他们都想独自喝完那壶酒,所以就定了一个规矩:每人在地上画一条蛇,谁画得最快,这壶酒就归谁。有一个人很快就把蛇画好了。他正打算喝这壶酒时,看见别人都还在忙着画,就决定给蛇再画上几只脚。结果,他的蛇脚还没加完,另一个人已经把蛇画好了。那人一下把酒壶夺了过去,说:“有谁见过长脚的蛇?”。这个故事告诉我们这样的道理:做得过分和做得不够都是不对的
