    Let's travel along A Bite of China III, another journey of food and culture,{#blank#}10{#/blank#}will never let you down!

    Way back in 1674, a frog helped Antoni van Leeuwenhoek make an incredible discovery. Antoni was an amateur scientist from Holland, so fascinated by microscopes {#blank#}1{#/blank#} he'd built some of his own. One rainy day, as he went for a walk, a leaping frog {#blank#}2{#/blank#}(draw) his attention to a puddle.

    Antoni collected a drop of puddle water and put it{#blank#}3{#/blank#} his microscope. He was amazed{#blank#}4{#/blank#} (see) a whole community of creatures swimming in this one drop — tiny beings no one had ever seen before.

    These tiny beings, called microbes, are everywhere: in dirt, in food and on your kitchen table. People {#blank#}5{#/blank#} (cover) in them, too.{#blank#}6{#/blank#} you were to count all the microbes on and inside your body, you would find your body has more microbes than the world has people — over 6 billion!

    Microbes can't survive on {#blank#}7{#/blank#}(they) own. They need food. After {#blank#}8{#/blank#}(settle) into a home — you, for instance — they steal vitamins and other nutrients and leave behind dead cells and poisonous liquids called toxins. Some microbes can make you sick. People usually call these ones germs{#blank#}9{#/blank#} (lucky) for you, there are more {#blank#}10{#/blank#} (help) microbes, working together to keep you healthy, than bad ones.

    More than 700 years ago, a 17-year-old Italian youth followed his father and uncle on a journey to the East, dreaming about the mysteries of China. The three set{#blank#}1{#/blank#} on a path that might have frightened even the most ambitious travellers. The young adventurer was Marco Polo.

    Having a talent for languages，Marco Polo learned to speak Mongolian and Chinese. Later under the orders of Kublai Khan, he{#blank#}2{#/blank#}(travel) far and wide across China. Along the way, he stopped {#blank#}3{#/blank#} (record) detailed notes about the local customs, geography and values of the people, so as to report back to the Khan.

    Marco Polo returned to Venice 24 years later. With{#blank#}4{#/blank#} (count) treasures brought back from the East, he became{#blank#}5{#/blank#} wealthy man overnight.{#blank#}6{#/blank#} he witnessed in China aroused much interest among his countrymen. Marco Polo's journey to China and the contents of his{#blank#}7{#/blank#} (vivid) written book, The Travels of Marco Polo, which{#blank#}8{#/blank#} (think) to be a fairy tale in Europe at the time, triggered a wave of European interest in the Orient.

    Marco Polo's story is both one about an explorer's search riches and a Westerner{#blank#}9{#/blank#} (follow) his dream to reach China. More than 700 years later, China, the once mysterious Oriental nation，is igniting the Chinese dream of many modem Marco Polos, attracted by its rapid {#blank#}10{#/blank#}(develop) and its growing importance in the world.

    Brave and {#blank#}1{#/blank#}(intelligence), the tiny mouse from the US cartoon series Tom and Jerry is loved and remembered by fans worldwide.

    Recently, scientists from Britain and Canada have created super-clever mice by {#blank#}2{#/blank#}(change) a single gene (基因). In the study, {#blank#}3{#/blank#}(research) changed one of the mice's genes to stop the PDE4B enzyme (酶), a substance found in the human brain, {#blank#}4{#/blank#} working.

    After that, they ran several tests on the {#blank#}5{#/blank#}(behave) and found they tended to learn{#blank#}6{#/blank#}(fast), remember events for longer and {#blank#}7{#/blank#}(solution) difficult problems better than normal mice. The mice also suffered less anxiety (焦虑) and showed {#blank#}8{#/blank#} fear of cats, their natural enemy.

    A team from the UK's Leeds University is now trying developing drugs (药品){#blank#}9{#/blank#} could block the PDE4B enzyme. {#blank#}10{#/blank#}(hope), the drugs could help with treatments for brain conditions such as Alzheimer's disease (老年痴呆症).
