We are naturally drawn to friends and colleagues with familiar voices, scientists have found. People prefer those who have a similar accent, intonation and tone of voice to themselves, they discovered.

    Previous research has focused on how male or female a voice sounds. Men with deeper voices and women with slightly higher voices were thought to sound more attractive, because they suggest a bigger or a smaller body.

    But the new study, published by a linguistics expert in Canada, suggests there is a more complex mechanism (机制) at play. Dr Molly Babel, from the University of British Columbia in Canada, said, “The voice is an amazingly flexible tool that we use to construct our identity. Very few things in our voices are changeless, so we felt that our preferences had to be about more than a person's shape and size.”

    She recorded 30 volunteers' voices and asked each to rate the others' attractiveness on a range from one to nine. Each participant was from western America, with similar accents. The people we assessed were all in the same dialect group, but they showed that dialect to different degrees.

     “We seem to like people who sound like we sound, and we like people who fit within what we know,” Dr Babel said. She also found that breathy voices in women—typified by the famous American actress Marilyn Monroe-were seen as more attractive.

    The breathy tone, caused by younger and thinner vocal cords (声带), implied youthfulness and health. A creaky (咯吱作响的) voice, suggesting a person has a cold, is tired or smokes, was seen as unattractive. The participants preferred men who spoke with a shorter average word length and deeper voices.

    Sitting is an art that isn't getting passed along. People these days feel as though they have to be doing something. If they are not working, they are jogging, or playing tennis or golf to guard against illnesses, or taking courses to improve their minds or bodies -- or they are parked in front of the TV. Sitting in front of the TV isn't sitting -- it's watching.

    People used to sit a whole lot. You would walk down the street or drive down the road, and there they would be, out on the doorsteps, sitting. You could go to the grocery to buy some garlic or some fruits and vegetables and sit on the bench out front m the summer or around the fire in the winter. You could go down to the store to buy an outer garment, an electric grill or anything else. There were sitting benches out in the town square. At the garage, there were straight-backed chairs. There among the oilcans and tires and spare parts, you could kick back and sit.

    Houses used to have sitting rooms, where the grown-ups would go after Sunday dinner. Mom and Dad, Grandpa and Aunt Ruby would gather round, sit and digest (消化) the fried chicken and talk about Aunt Ethel's illness, and how well the minister did today. They may just talk a load of garbage and even gesture with their hands when they become excited. Outside, the younger generation, the children would play on the ground, and the afternoon would pass by in a comfortable haze（ 悠闲的氛围).

    That sort of thing looks like doing nothing. A recharging battery (正充电的电池) doesn't look as if it's doing anything either. Sitting restores your soul. If you want to enjoy a truly full life, don't just do something--sit there.

    Modern day robots may not be as entertaining as R2D2 or the robot from Lost in Space, but robots are very important to space exploration and are being used in a variety of different ways for several important reasons.

    Robots make great explorers on planets, moons, and other landing areas. Aside from the earth, just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient fortunate for humans to explore. The air on most other planets is insufficient for humans to breathe, making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand. Plus there would be complications with radiation, weather, and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions.

    Robots are designed for collecting scientific data. Robots are also able to perform many tasks at one time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals, analyzing ground samples, to finding water are all performed much quicker and accurately by robots.

The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans, but also enough | food and water to keep them alive for the duration of the trip. Moreover, robots have no problems working for hours on end. Robots never complain, they don't require food or water, and they never need a bathroom break.

    Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.

    Born in Detroit, Michigan, on January 10^th, 1928. Philip Levine was formally educated in the Detroit public school system. After graduation from university, Levine worked a number of industrial jobs, including the night work in factories, reading and writing poems in his off hours. In 1953, he studied at the University of Iowa. There, Levine met Robert Lowell and John Berryman, whom Levine called his “one great guide”.

    About writing poems, Levine wrote: “I believed even then that if I could change my experience into poems I would give it the value and honor that it did not begin to have on its own. I thought too that if I could write about it, I could come to understand it: I believed that if I could understand my life——or at least the part my work played in it——I could write it with some degree of joy, something obviously missing from my life.”

    Levine published (出版) his first collection of poems. On the Edge in 1961, followed by Not This Pig in 1968. Throughout his life Levine published many books of poems, winning many prizes. A review said: “Levine writes poems about the bravery of men, physical labor, simple pleasures and strong feelings, often set in working-class Detroit or in central California, where he worked or lived.”

    He taught for many years at California State University, Fresno and served as Distinguished Poet in Residence for the Creative Writing Program at New York University. After retiring from teaching, Levine divided his time between Brooklyn, New York, and Fresno, California, until his death on February 14^th, 2015. His final poem collection, The Last Shift, as well as a collection of essays (短文) and other writings, My Lost Poets: A Life in Poetry, were published in 2016.

    Breakdancing is set to make its first debut (亮相) as an Olympic sport at Paris 2024, Tony Estanguet, head of the Paris organizing committee, said on February 21st. Skateboarding, sport climbing and surfing, which have already been added to the programme for the 2020 Tokyo Olympics, have been invited to return in Paris four years later.

    Tony Estanguet said the choices responded to a need to make the Olympics "more urban" and "more artistic". We have chosen to present the International Olympic Committee (IOC) with the four sports because they are creative, appealing to youth and completely in line with our vision. They reflect perfectly Paris 2024's identity.

    Breakdancing is an example of a sport "Which can be played anywhere and anytime in urban and other environment." It appeared at the 2018 Youth Olympics in Buenos Aires in the form of head-to-head "battles". In competitive breakdancing, "breakers" face off in "battles" against each other, either as individuals or teams. Breakdancers use a mix of physical and artistic skills combining elements from gymnastics or acrobatics (杂技).

    The IOC had announced that the number of competitors at Paris 2024 would be restricted to 10, 500, which limited the opportunity to add sports. But the organizers said the inclusion of the four sports in Paris would not necessitate the construction of permanent facilities and would involve just 248 competitors, of which 32 would he in breakdancing. The surfing events are likely to be held in established surf centres such as Biarritz or Lacanau in southwest France.

    The inclusion still need to be rubberstamped by the IOC, which is expected to decide on which sports to add in Paris after next years' Tokyo Games.

    The most important thing to keep in mind when you're going into high school is to be yourself. Besides, some high school teachers will not care about things like how much homework you have already had in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

    I think almost every kid feels both nervous and excited before their first day of high school. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!

    When I started high school, I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    I'm not going to lie. The first day is kind of frightening. But you'll get used to it. Don't be afraid of anyone; some students may pick on (故意刁难) you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week, it's really not bad at all. Don't worry.
