Singing aloud will not just lift the spiritsits good for your physical health as well. Filling the lungs with air， increasing the heart rate and getting blood pumping round the body faster can all help our physical health.

It also brings a great amount of happiness. It is impossible to sing well with a long face because it affects your pitch(音高). ” Professor Graham Welch， who leads the International Music Education Research Centre at the University of London， has spent more than 30 years studying the effects of singing. He says that singing is a form of exercise. It means were also having a strong aerobic activity(有氧运动) when were singing， which results in increasing the feeling of pleasure while decreasing that of stress. “And communal singinglike in a singing group， a church service or even a singsong in the pubhelps improve our sense of self-respect. It increases our sense of satisfaction with ourselves， a greater sense of feeling included. ” Helen Astrid， a singing teacher， also sees the great effects that singing brings. “It lifts us up on a spiritual level， it helps our self-respect， and its great for all ages from small kids to granniesyou can have a good sing and let your hair down. ” But she warns people not to have too many beers or glasses of wine， though a glass may help them gather courage before taking to the stage during the holidays.1.Heart Research UK holds a campaign to_.A.encourage people to sing for God at ChristmasB.study the effects of singing on peopleC.get people to sing and improve their healthD.bring happiness to people during holidays2.The underlined part“let your hair down” probably means_.A.feel at ease B.protect yourselfC.dress casually D.cover your nervousness3.What can we infer from the passage?A.Singing at Christmas is good for health.B.In a low mood one is not able to sing well.C.Experts have disagreement on singing.D.Singing is the same as other aerobic activities.4.Which is the best title of the passage?A.KaraokeBest Place for SingingB.ChristmasBest Time for SingingC.SingingHealthy but DifficultD.For HealthLets SingLast weekend, 20,000 people gathered in the state of Georgia to watch students from 28 countries compete with robots they built. More than ten thousand students and more than five hundred robots took part in the competition.The students and their robots competed at the FIRST Championship at the Georgia Dome in Atlanta. FIRST is the short way of saying the organizations complete name： For Inspiration and Recognition of Science and Technology.Almost 1,700 high school teams entered a level of competition called LUNACY.In January, the organization sent supplies for robots to each team. The teams had six weeks to build robots that could compete in the LUNACY game. The playing area had six robots, three on each team. Each robot had another vehicle, or trailer(拖车)， connected to it. The robots had to pick up large balls and throw them into the trailers of opposing robots. The robots were moving on a surface where they could slide. An alliance(联盟) of teams from California， Illinois and Michigan won the LUNACY competition.A second competition involved building a robot that could travel on uneven surfaces, move objects with unusual shapes and resist physical stress.Another competition was for younger students， aged from 9 to 14.They had to design, build and program robots to explore the Earths climate.American inventor Dean Kamen started FIRST in 1989. The organization holds robot competitions around the world. It offers programs that help young people learn more about science， technology， engineering and mathematics， which build life skills. Many companies provide support to the organization.Mister Kamen says the goal is about more than building robots. He says the student competitors showed they could deal with difficult technological problems. And he says that is good news because the world needs creative thinkers to help with increasingly complex problems in the future.5.The Robot Competition was organized by_Athe state of GeorgiaBan organization named FIRSTCAmerican inventor Dean KamenDsome companies from California6.The robots in the LUNACY game are able to_Atravel on uneven surfacesBexplore the Earths climateCthrow balls into the trailers
