Brighton is the{#blank#}1{#/blank#} (health)city in Britain with the highest level of personal trainers, yoga clubs and health food stores, according to a survey related on Friday.

    The survey, {#blank#}2{#/blank#} looks at 19 statistics covering health, {#blank#}3{#/blank#} （fit）and environment, says Brighton has the highest number of residents {#blank#}4{#/blank#} (eat) at least five kinds of fruit and vegetables a day.

    The survey, {#blank#}5{#/blank#} (conduct) for the Sky Travel channel, has compared 15 cities across the UK. It says Brighton residents live {#blank#}6{#/blank#} an average age of 78 years old. They are twice as likely {#blank#}7{#/blank#} (walk) or cycle to work as the people living in other parts of Britain.

    In {#blank#}8{#/blank#} （compare）with the national average, Brighton has nearly a third more health food stores and personal trainers than{#blank#}9{#/blank#} in any other city in Britain. It has twice many yoga clubs, and the level of fat residents is below the national average.

    Meanwhile, {#blank#}10{#/blank#} survey also finds that Brighton residents have the best levels of cholesterol (胆固醇) and blood pressure in Britain.

    Paul Lucas can often be seen walking around the city of San Francisco. Sometimes people are {#blank#}1{#/blank#} (surprise) to see him walking without any shoes or socks,{#blank#}2{#/blank#} Lucas doesn't mind at all. He likes to walk barefoot, and {#blank#}3{#/blank#} do 640 other members of Dirty Sole Society, the club that Lucas {#blank#}4{#/blank#} (start) years ago. Lucas' idea for this is to encourage others to live {#blank#}5{#/blank#} (free)－free of shoes.

    According to Lucas, the barefoot life has many {#blank#}6{#/blank#} (advantage). The most important is simply that it feels good. He also says that walking barefoot allows you to experience the world directly by {#blank#}7{#/blank#} (touch) it with your feet. In addition, the feet do not smell so much {#blank#}8{#/blank#} they stay dry,{#blank#}9{#/blank#} (make) it hard for bacteria(细菌)  to grow. And, of course, walking barefoot keeps your feet in good shape, so it's actually {#blank#}10{#/blank#} (healthy) than wearing shoes.

    In 1969, Armstrong {#blank#}1{#/blank#}(successful) set foot on the Moon. This was {#blank#}2{#/blank#} first time anyone had walked on the surface of another world. More astronauts（宇航员）reached the Moon later, but nobody {#blank#}3{#/blank#}(visit) it since 1972. Do you think it's time we went back?

    {#blank#}4{#/blank#}(explore) of the Moon did continue after the astronauts left, but by robots instead {#blank#}5{#/blank#} people. Satellites have helped us learn more about our neighbour and shown that there {#blank#}6{#/blank#}(be) even more exploring to do, but astronauts would be needed!

    The problem is that sending humans to the Moon is very expensive. Even with all the new technology since Armstrong's time, it would cost so much for people {#blank#}7{#/blank#}(return) to the Moon.

    ESA (European Space Agency) wants to change that. ESA's idea isn't just to make the spaceships {#blank#}8{#/blank#}(they), but also to work with businesses here on Earth. ESA also wants to help businesses on Earth develop tools and technology {#blank#}9{#/blank#} will allow people to live on the Moon. If we can use resources（资源）on the Moon, then journeys there will be much {#blank#}10{#/blank#}(cheap). For example, what if we could get to water hidden deep within Moon rocks?

    After four years of living here, I have a better {#blank#}1{#/blank#}(understand) of northern China's food.  

    Northern China's hearty food is {#blank#}2{#/blank#}(general) more acceptable to Westerners. They can enjoy Beijing roast duck, beef and dairy from Inner Mongolia, and Korean dishes in the northeast. Northern China experiences cold and dry winters, and hot summers, {#blank#}3{#/blank#}(make) calories and salt replacement more important. As a result, northern dishes have strong flavors, compared with the south {#blank#}4{#/blank#} dishes are lighter in flavor.  

    Wheat is the main crop of northern China, and you will find a variety of wheat-flour {#blank#}5{#/blank#}(product). Rice is also eaten in the north, but it is certainly secondary to wheat. Dumplings are very popular in the north, {#blank#}6{#/blank#}(serve) with vinegar for dipping.  

    Northerners tend to eat more meat and dairy for the purpose {#blank#}7{#/blank#} fighting against the cold weather. Most meat dishes {#blank#}8{#/blank#}(base) on mutton, pork, beef,  chicken,  and fish.  

    {#blank#}9{#/blank#} are less fresh vegetables available because of the cold weather. Fruit is traditionally limited to a few hard seasonal varieties like apples, so it doesn't feature much in the cuisine, although the northwest is famous for {#blank#}10{#/blank#}(it) dried fruit and wine.  

    Miners have dangerous jobs because occasionally the earth sinks or falls apart. When this happens, miners are {#blank#}1{#/blank#}(trap) underground. They are buried {#blank#}2{#/blank#} they don't have air to breathe, food to eat, and water to drink, they will die. They {#blank#}3{#/blank#} not go without any of these things for long, but the first is the most important. {#blank#}4{#/blank#}is difficult to figure out where miners are and reach them in time. Trapped miners dream of {#blank#}5{#/blank#} (be) free and don't give up.

    In August 2010, 33 miners{#blank#}6{#/blank#} (go) to work in a mine in Chile, All of a sudden, a wall broke apart and rocks and dirt filled {#blank#}7{#/blank#} mine's exit. At first, people thought all the miners died. {#blank#}8{#/blank#} , after working for 17 days, people at the surface learned the miners were still alive. {#blank#}9{#/blank#}, people on the surface figured out where the miners were and dug a {#blank#}10{#/blank#}to send them food and water.

    Why do many of us find {#blank#}1{#/blank#} difficult or impossible to fall asleep in a bed other than our own? Is it because the bed is {#blank#}2{#/blank#} (comfort)? According to a new study published in Current Biology, a significant reason is {#blank#}3{#/blank#} the scientists call "first night effect". They believe that one side of the brain acts as a "night watch" to warn us about potential dangers. It forces us {#blank#}4{#/blank#} (stay) awake on the first night in a new environment.

    For the study, 35 young volunteers {#blank#}5{#/blank#} (ask) to sleep in a sleep lab for several days. Meanwhile, researchers watched their brain activities.

    According to the researchers, on their first night, the left brains were {#blank#}6{#/blank#} (active) than the right brains and people had a hard time sleeping. However, left-brain activity decreased as days went by, {#blank#}7{#/blank#} (fall) even to the point of complete calm. In this process, the participants got an increasingly better sleep experience.

    The {#blank#}8{#/blank#} (finding) suggest that the different rhythms of the sides of the brain affect our sleep. When the two sides work {#blank#}9{#/blank#} (different), the balance between them is broken. Thus, the brain can't relax and is sensitive to anything strange in the surroundings, just {#blank#}10{#/blank#} it is in the daytime.
