—No. On the contrary, I think it is very necessary.

    Tu Yoyo was honored with the Nobel Prize in Physiology or Medicine  {#blank#}1{#/blank#}Oct. 5. She was the first Chinese citizen {#blank#}2{#/blank#}(win) a Nobel Prize in science. Tu {#blank#}3{#/blank#}(share) the prize with the Irish-born William Campbell and Satoshi Omura of Japan.

    Tu is a researcher at the China Academy of Traditional Chinese Medicine now. She  {#blank#}4{#/blank#}(give) the prize for  {#blank#}5{#/blank#} (develop) artemisinin (青蒿素) , a new drug therapy against malaria( 疟疾)， {#blank#}6{#/blank#} has saved millions of lives worldwide, especially in developing countries.

    Tu and her colleagues joined a government project to find a new malaria drug in the late 1960s. They made 380 herbal extracts from two thousand recipes from traditional Chinese medical books. In 1971, after nearly two hundred  {#blank#}7{#/blank#} (fail), Tu's team  {#blank#}8{#/blank#}(final) found an extract that was 100% effective against the malaria parasites-atremisinin. In 2001, the World Health Organization made artemisinin {#blank#}9{#/blank#} (it) first choice in the treatment of malaria.

    “The discovery of artemisinin is a gift to mankind from traditional Chinese medicine. It's the achievement of the research team. Winning the prize is  {#blank#}10{#/blank#} honor for Chinese science and traditional Chinese medicine,” Tu said.

    The world's longest sea bridge {#blank#}1{#/blank#} (call) the Hong Kong-Zhuhai-Macau Bridge has opened. The bridge {#blank#}2{#/blank#} (link) Hong Kong and Macau to mainland China. {#blank#}3{#/blank#} took more than a decade to construct it. Builders had to make artificial islands in the Pearl River Delta {#blank#}4{#/blank#} (provide) the supports for the bridge. There is also a 6.7-kilometre underwater tunnel in the middle of the bridge, {#blank#}5{#/blank#} allows ships to sail through the Delta. The new bridge stretches {#blank#}6{#/blank#} (long) than 14 Golden Gate Bridges lined up end to end. The bridge will {#blank#}7{#/blank#} (great) cut the time it takes to travel from mainland China to Hong Kong and Macau.

    Chinese President Xi attended the opening ceremony of the bridge. He hopes the new crossing will help to connect 68 million people in 11 different {#blank#}8{#/blank#} (city). China's government believes that up to 29,000 cars will cross the sea link daily by the year 2030. A trade and tourism expert said, “This makes Hong Kong a lot more accessible for goods, passengers and trade, so this is a benefit {#blank#}9{#/blank#}the economic perspective.” The bridge will be open to tourists to drive across it. However, local car owners will not be able to cross the bridge {#blank#}10{#/blank#} they have a special permit. Most drivers will take a shuttle bus to make the journey.

    The Amber Room was made of several tons of amber. The amber which{#blank#}1{#/blank#}(select) had a beautiful yellow-brown colour like honey. The design of the room was in the fancy style popular in those days. It was also a treasure decorated with gold and jewels, {#blank#}2{#/blank#}took the country's best artists about ten years {#blank#}3{#/blank#} (make).

    The Amber Room was designed for the palace of Frederick I. {#blank#}4{#/blank#}, the next King of Prussia Frederick William I, to whom the Amber Room belonged, decided not to keep it. In 1716 he gave {#blank#}5{#/blank#} to Peter the Great. {#blank#}6{#/blank#} return, the Czar sent him a troop of his best soldiers. So the Amber Room became part of the Czars winter palace in St Petersburg.

    Later, Catherine II had the Amber Room {#blank#}7{#/blank#}(move)to a palace outside St Petersburg where she spent her summers. She told her artists to add more details to it. In 1770 the room was completed the way she wanted. Almost six hundred candles lit the room and its mirrors and pictures shone like gold.{#blank#}8{#/blank#}(lucky), although the Amber Room was considered one of the{#blank#}9{#/blank#} (wonder)of the world, it is now{#blank#}10{#/blank#}(miss).

    A hotel chain is employing human bed warmers to help guests get a good night's sleep. {#blank#}1{#/blank#} (dress) in special all-in-one sleeping suits, the walking electric blankets are sent to warm the beds of guests staying at the Holiday Inn {#blank#}2{#/blank#} they get under the covers.

    Dr Chris Idzikowski, {#blank#}3{#/blank#} (direct) of the Edinburgh Sleep Centre, said the idea could help people get off to sleep. He {#blank#}4{#/blank#} (explain) that "There's plenty of scientific evidence to show that sleep starts at the beginning of the night {#blank#}5{#/blank#} body temperature starts to drop. The drop occurs partly because the blood vessels (血管) {#blank#}6{#/blank#} the hands, face and feet open up and release heat." "A warm bed –approximately 20 to 24 degrees Celsuis –is {#blank#}7{#/blank#} good way to start this process while a cold bed isn't. It helps people sleep well especially as it's taking much {#blank#}8{#/blank#} (long) for them to warm up when they come in from the snow."

    Dr Chris Idzikowski and {#blank#}9{#/blank#} (he) colleague Jane Bednall said the idea was like "having a giant hot water bottle in your bed". The five-minute free bed warming sessions will be tried out in London and Manchester {#blank#}10{#/blank#} the end of next month.
