    On October 31st, 2009, Chinese famous scientist Qian Xuesen, died in Beijing when he was 98 years old. He is famous as “the country's father of space technology and king of rocketry”.

    Qian was born in 1911 in Hangzhou. He left for the United States after winning a scholarship to graduate school in 1936. He studied at the Massachusetts Institute of Technology and later at the California Institute of Technology.

    Qian began his career in the US and was regarded as one of the brightest minds in the new field of aeronautics（航空学) before returning to China in 1955.

    After he returned, Qian set up the first missile（导弹）and rocket research institute（学院) of China. The institute later helped start Chinese space program. He led the development of China's first nuclear-armed ballistic missile (弹道导弹) and worked on its first satellite.

    He retired in the year before Chinese manned space program was launched in 1992. But his research formed the basis（形成基础）for the Long March CZ -2F rocket that carried astronaut Yang Liwei into orbit in 2003.

    In August, 2009, Chinese Premier Wen Jiabao visited Qian and praised him for devoting his life to Chinese defense technologies. Qian told him, “I'm trying to live to be 100 years old”.

    Scientists are using robots to study the health of waters in and around Venice, Italy. The robots are designed to act like fish, other underwater creatures and plants. The scientists are working with several universities and research centers as part of a group called subCULTron. The European Union gives money to the project as part of its Horizon 2020 program whose aim is to take great ideas from the lab to the market and support science and innovation (创新) in Europe. The scientists want to use the artificial intelligence of the robots to help humans understand what is happening under the water of the Venice lagoon (潟湖).

    SubCULTron, a collective artificial intelligence project, plans to create the biggest shoal (鱼群) of robot fish in the world. The project's aim is to improve knowledge of the seabed and try to turn human abilities into hi-tech items.

    Alexandre Campo, a computer scientist, says the scientists have looked at the way animals learn to work in groups to understand how robots can learn to work together. The subCULTron project wants its robots to learn to work together so they can watch out for changes and new problems in the water.

    One problem the researchers had in the beginning was how the robots would communicate with each other. Wi-Fi and GPS equipment don't work underwater. Instead，the robots can use sonar (声呐) and an electric field.

    Another problem was charging batteries. The robots come up to the water's surface and stay near a boat or a power station to charge without any electrical cables. Besides, how to be water- proof, especially for some key pads of the robots, was really tough. Fortunately, a special mixture has been created to be pinned on the robot, which successfully stands the test of water.

    The health state of the lagoon is pretty good. There are no industrial polluters, and the city now has a modem sewer (污水管) system. It's not like before when all the waste flushed directly into the water. The robots in Venice will continue their work until 2019. The subCULTron project hopes they develop into “an artificial society underneath the water surface” that serves “a human society above the water”.

    We were high in the mountains of Xishuangbanna, as far south as you can get in Yunnan, skirting the borders of Myanmar and Laos. The drive was typical, textbook beauty: mountains thick with rubber tree forests, pu'er tea plantations and banana palms and tiny Dai villages. Hidden among the fields of green, I spotted an odd collection of wooden boxes near a tent on the side of the road{#blank#}1{#/blank#}

    We had run into the current home of Wei Dajing, a 17-year-old apprentice (学徒) beekeeper who was manning his hives. Wei was fresh to the beekeeping life, and had been on the job for just two months and was here to learn from a master beekeeper. Their tent and hive set-up is always temporary{#blank#}2{#/blank#}This particular spot was stationed at a sunny patch of yellow flowers. Once these flowers die, the rubber trees will be flowering, so we will move toward them,” he told Sam.

    Like thieves in the night, the beekeepers will stealthily pack up their hives in the dark once the bees go to sleep. “They are most active around midday when they are collecting their nectar (花蜜){#blank#}3{#/blank#}Wei explained.

    The hives were humming, and bees were invasively buzzing around Wei as he spoke to us. Pieces of fruit lay drying among the hives, used to feed the bees and give them an extra boost of energy once Wei bottles up their hard-earned honey. Sam, who also has a couple of his own small hives in his backyard, tells us you must always leave a little bit of honey in the hive{#blank#}4{#/blank#}

    We waved goodbye to Wei. Back at Sam's house, he gave us a bowlful of local honey{#blank#}5{#/blank#}Lacking the usual sweetness of honey but instead rich with a more savory, spiced flavor, it tasted just like China.

A. It was smooth, thin and runny.

B. Wei skillfully collected honey from the hives.

C. Otherwise the bees get fed up and abandon you.

D. Maybe it is the flowers that give such unique taste to the honey.

E. By 10 pm they are asleep in their hives, which is when we move.

F. I asked our excellent guide and new best friend, Sam, to pull over.

G. Wei and his master move their camp as the flowers bloom and die.

                                          How to Care for Your Ears?

    Ears not only let us hear, but they also play a role in maintaining our balance, which is vital to our ability to function in daily life. Yet, we ignore them. We can't even see our ears, except in a mirror. We take it for granted what they do for us day in and day out—until we notice something wrong, such as when an earache strikes or when we start having to ask people to repeat what they say.{#blank#}1{#/blank#}

    ◆Clean your ear with a washcloth—covered finger only.

     Never put anything inside your ear canal, including cotton swabs(药签).{#blank#}2{#/blank#}

    ◆Leave earwax（耳垢）alone.

    Wax is your ear's way of eliminating（消除）anything foreign that gets into the ear canal.{#blank#}3{#/blank#}If you find you have too much earwax, use a few drops of earwax remover in the canal. After a few minutes, wash the ear with warm water.

    ◆Avoid noisy places.

    Rock concerts and construction sites are just a few places that frequently have noise levels that can damage hearing. Any place where you have to shout to be heard should be avoided.

    ◆{#blank#}4{#/blank#}

    Be careful not to play MP3 too loud, especially if using earphone.

    ◆Be careful with illness and medications.

    Respiratory（呼吸的）illnesses should be treated to avoid their spread to the ears. Certain medications can damage hearing, so follow the directions carefully before taking them.

    See your doctor if you suffer from sudden hearing loss or hear noises in your head.{#blank#}5{#/blank#}

    You may not have heard of it before, but solid rain (固体雨)has been helping Mexican farmers fight droughts(干旱) for over ten years. The magic solid rain looks like sugar and it can take in water up to 500 times as its own size and keep it in the ground for up to a year.

    The story of solid rain began in 1970, when American scientists developed a product used to take in water and help keep babies' bottoms dry. However, a Mexican chemical engineer saw this magic product as an opportunity to fight the drought. He developed a different kind of the product, which could be mixed with soil and slowly feed water to crops over a long period of time. His company, Solid Rain, has been quietly selling the product to Mexican farmers for over 10 years.

    Solid rain seems to be working wonders in Mexico. However, it has not come into use around the world. Well, that's mainly because a lot of people still don't know about it. The Mexican company has invested (投资) almost nothing into marketing, relying instead on word of mouth between Mexican farmers. However, recently, they have gotten requests from other dry countries like India and Australia.

    Solid rain has received the Ecology and Environment Award, but it has also received some negative views. Dr. Linda Scott says that the product is hardly new and that there is no scientific evidence that it can hold water for a year or last in the ground for ten years. Besides, solid rain can cause more harm than good in certain conditions.

    However, real-life use seems to show that solid rain is actually of great use to their farms. Frank Torres, a former green bean farmer used to rely on it even though drought wasn't such a big issue. He said that the production had increased by 50%.
