Music is in the comers of everyday life. It is said to be {#blank#}1{#/blank#}(benefit) to us both physically and mentally.

    There are many ways to make music. For example, if you blow into bamboos or shells, {#blank#}2{#/blank#}(permit) air to come in, they can produce pleasant music. A recent discovery suggests that music is played much earlier than we think. In 1995, deep in {#blank#}3{#/blank#}cave in Slovenia occupied 45,000 years ago by Neanderthals, a leg bone of a bear with four finger holes was found, {#blank#}4{#/blank#} suggested that flutes（笛子）had come into {#blank#}5{#/blank#}(exist) at that time. Later, many other {#blank#}6{#/blank#}(tradition) musical instruments like drums were unearthed. Ancient people even {#blank#}7{#/blank#}(seek) a way to make music out of a bow that {#blank#}8{#/blank#}(intend) for hunting, so we have to admit that they did have a great gift {#blank#}9{#/blank#}music. But if accurately dated, the Neanderthal flute is by far the {#blank#}10{#/blank#}(early) known example of music.

    Now music can be found in every known culture, and even the most isolated（孤立的）groups have a certain form of music.

    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.  

    Have you ever awakened and felt like you couldn't move? If so, it {#blank#}1{#/blank#} (probable) scared you. You may have thought something terrible had happened to you. Actually, many people have this experience on a regular basis. It {#blank#}2{#/blank#} (call) sleep paralysis(瘫痪). {#blank#}3{#/blank#} it sounds scary, it is normal.

    Sleep paralysis happens when a person is falling asleep or waking up. As the person falls asleep, his or her body slows down. Usually the person's mind {#blank#}4{#/blank#}(relax) at the same time, but occasionally the mind stays awake{#blank#}5{#/blank#}(long) than the body. As a result, the person can be conscious, or aware, but have trouble moving or {#blank#}6{#/blank#}(speak). Sleep paralysis can also occur as you wake up. Fortunately, the condition rarely lasts for more than a few seconds. {#blank#}7{#/blank#}(move) and speech soon return to normal.

    Some people report unusual experiences during sleep paralysis. They may hear, see or feel things {#blank#}8{#/blank#}don't exist. At one time, people {#blank#}9{#/blank#}(think) that ghosts or monsters had entered the room and were holding them down，keeping them from moving. Science has helped us understand that such visions are actually part of sleep paralysis. Now we know that getting too little sleep, taking certain medications(药物), and changing your sleep schedule can cause sleep paralysis. This condition can be scary, but it's just a trick that you mind is playing {#blank#}10{#/blank#} your body.
