In our daily life, we have developed a lot of habits, such as, eating habit, study habit, reading habit, etc. However, taking the time to develop a sleep habit is probably the last thing on your mind and some sleep advice simply can't be forgotten. {#blank#}1{#/blank#}.

Watching TV until you fall asleep

    It has nothing to do with what you watch —TV news isn't a better pre-sleep choice than TV series. {#blank#}2{#/blank#}. The bright light keeps you awake all the night. So even if you nod off (in front of the TV, for example), you probably won't stay asleep for long.

Sleeping with pets

    {#blank#}3{#/blank#}. They get comfortable, and then they move. This goes on all night, and whether you admit it or not, it interrupts your ability to get the level of sleep needed to feel rested.

Eating fatty, heavy foods too close to bedtime

    Heartburn (烧心，胃痛) strikes anyone of any age, but it's the most common GI disorder (胃肠失调) in older adults. If you've ever tried to go to sleep after eating a fatty meal, you've probably found the discomfort of stomach preventing you from falling asleep or staying asleep.

    Remember how poorly you sleep when you have a fever—turning over and over again, never really feeling rested? Well, heavy exercise too close to bedtime has the same effect — it raises your body temperature so that your sleep is disturbed until your body temperature drops to normal, which may take several hours.

Accepting snoring (打呼噜) as normal sleep behavior

    Snoring may seem as common as breathing, but it's considered the biggest sleep killer, and it's linked to several causes: sleeping on your back, being overweight, having a cold, drinking, or taking drugs. {#blank#}5{#/blank#}. For the snorer, it disturbs sleep by awakening him/her every so often in order to breathe normally. For the partner, the noise can be unbearable.

    When the residents of Buenos Aires want to change the pesos they do not trust into the dollars they do, they go to an office that acts as a front for thriving illegal exchange market.

    As the couriers carry their bundles of pesos around Buenos Aires, they pass grand buildings like the Teatro Colon, an opera house that opened in 1908, and the Retiro railway station, completed in 1915. In the 43 years leading up to 1914, GDP had grown at an annual rate of 6%, the fastest recorded in the world. In 1914 half of Buenos Aires's population was foreign-born. Its income per head was 92% of the average of 16 rich economies.

    It never got better than this. Its income per head is now 43% of those same 16 rich economies; it trails Chile and Uruguay in its own backyard.

    The country's dramatic decline has long puzzled economists. “If a guy has been hit___shots it's hard to work out which one of them killed him.” says Rafael di Tella. But three deep-lying explanations help to throw light on the country's decline. Firstly, Argentina may have been rich 100 years ago but it was not modern. The second theory stresses the role of trade policy. Thirdly, when it needed to change, Argentina lacked the institutions to create successful policies.

    Argentina was rich in 1914 because of commodities; its industrial base was only weakly developed. The landowners who made Argentina rich were not so bothered about educating it: cheap labor was what counted.

    Without a good education system, Argentina struggled to create competitive industries. It had benefited from technology in its Belle Epoque period, but Argentina mainly consumed technology from abroad rather than inventing its own.

    Argentina had become rich by making a triple bet on agriculture, open market and Britain, its biggest trading partner. If that bet turned sour, it would require a severe adjustment. The First World War delivered the initial blow to trade. Next came the Depression, which crushed the open trading system on which Argentina depended. Dependence on Britain, another country in decline, backfired(失败) as Argentina's favored export market signed preferential deals with Commonwealth countries.

    After the Second World War, when the rich world began its slow return to free trade with the negotiation of the General Agreement on Tariffs and Trade in 1947, Argentina had become a more closed economy. An institution to control foreign trade was created in 1946; the share of trade as a percentage of GDP continued to fall. High food prices meant big profits for farmers but empty stomachs for ordinary Argentines. Open borders increased farmers' taking but sharpened competition from abroad for domestic industry. Heavy export taxes on crops allow the state to top up its decreasing foreign-exchange reserves; limits on wheat exports create surpluses(过剩) that drive down local prices. But they also dissuade farmers from planting more land, enabling other countries to steal market shares.

    Here are some of the smartest animals in the world.

Pigs

    Pigs are actually very smart animals. Pigs are one of the cleanest if they are given a choice. If you provide them with enough space, they will make sure they separate their dining area from their living space. Studies have also shown that they can actually be good at video games. To get food, they will follow other pigs and then steal it from right under their noses. The victimized(受害的)pigs will then come out wiser from this. They will change their behavior next time to prevent other pigs from stealing from them.

Crows

    They are smart and creative, with the highest IQ among all birds. Crows have been known to throw nuts and shells on a road so that cars will drive over and open them. They also have the ability to make knives to cut leaves and grass.

Elephants

    They have extremely large brains, even bigger than humans'. They bury(埋葬)their dead families and friends properly, the only other animal to do this besides humans. They also know which leaves are medicinal and will eat specific plants depending on the sickness they are feeling. They also have the ability to recognize themselves in the mirror.

Bottlenose Dolphins

    They actually have the ability to watch television on the their own because of their ability to process acoustic and visual(视觉和听觉)information at the same time. They can also recognize themselves in the mirror, which they use to inspect their own bodies. Their comprehension skills are very high. Studies have shown that they even have the ability to choose the “I don't know” option during difficult tests.

    Are you the type of person who always says “yes”? I've come to learn that it is very important to learn to say NO! It's okay. People are still going to like you. They may even respect you more because they know you are honest.

    I'm not saying to say “no" to someone who really needs your help. I'm talking about refusing that meeting that you really do not want to attend or that birthday party that you don't want to be a guest at.

    Think for a moment how you feel when you say YES to something that you really don't want to do. If you're like I once was，you can't sleep at night and you think about it too much. It weighs on your mind. You try to find ways out. Whatever you're saying to yourself, if you really wanted to go, you wouldn't have all of these thoughts.

    So, why not just say NO from the beginning? Maybe you feel like if you don't show up at the meeting (by the way, it is not one you must attend) your boss isn't going to like you or your co-workers won't respect you. Maybe you feel as if your mom, dad or sisters won't love you as much if you don't do everything for them that they ask every occasion.

    If these people are your true friends, family members, or a good boss, they will like or love you the same no matter what. People treat you the way you usually use, and if you're someone who always says “yes” then that's what they're expecting.

You need to do what is right for you. Of course we do have real responsibilities in life to do, but we do not have to do everything others want us to do.

    My daughter Kelly is a cautious person. She needs to warm up to situations, and is hesitant to try new things. When with close friends, she becomes a leader who laughs loudly and chants, "Girls rule, boys drool." But when that comfort zone is not around her, she is shy and nervous.

    This has been challenging for me at times. "Shy" is not a word that I think has ever been used to describe me. But this has been a year of firsts for my girl that has filled her with a new sense of confidence. This year she moved to lap lane in swimming where she was preparing for a swim team. This year she learned to ride a bike without training wheels. And this year she completed her first kids' triathlon(三项全能).

    On Saturday, with a thunderstorm coming soon and my son's birthday party later in the day, we all went out in the dark of the morning for Kelly to participate in her first triathlon. We practiced transitions from swim to bike to run with her, we got all the equipment she'd need, and we kept talking about the race. But as we waited the two hours for the older kids to finish before her turn, she held my leg a little harder and told me she loved me a few too many times. She was nervous but trying to keep it together.

    And then it was her turn. From the second she jumped into the water, my heart soared. My daughter transformed into the most confident human being I had ever seen. She dominated that swim, crushed that bike ride and ran to the finish with the biggest smile on her face.

    I can honestly say that I never felt so proud of someone in my entire life. It wasn't because she did a sport or anything like that. It was because she was afraid of something and conquered that fear with confidence and a fire I hadn't seen before.

    All day I would find myself just looking over at her and smiling. She might be wearing the finalist medal but I felt like I won that day. I won the chance to see my girl shine.

    Shine on, sweet baby.

Beijing is the capital city of China. It {#blank#}1{#/blank#} (cover) an area of around 17, 000 square kilometers, in which there are different kinds of bird habitats (栖息地), {#blank#}2{#/blank#} (include) grassland, scrubland (灌木丛林地), wetland, and also agricultural land. Researchers call these areas "service stations," where migrating (迁徙) birds stop {#blank#}3{#/blank#} (rest) and feed. But the birds ‘"service stations" re {#blank#}4{#/blank#} (rapid) closing in Beijing, as the city considers scrubland, grassland and old agricultural land to be "dirty" and "ugly". 

The loss of grassland and scrubland is already having a major influence {#blank#}5{#/blank#} Beijing's bird life. In the north of Beijing, the land around Miyun used to be visited by thousands of cranes (鹤). Now, much of that land is covered with man-made forest and {#blank#}6{#/blank#} number of cranes there has greatly fallen. 

"Cranes are rare and valuable animals in China. At Miyun, a festival {#blank#}7{#/blank#} (hold) to celebrate the migration of cranes every year," one researcher, Townshend, says. "Because it is Beijing, we can attract many people—both local people {#blank#}8{#/blank#} visitors."

"More cooperation (合作) between {#blank#}9{#/blank#} (country) is needed," Townshend adds. "Migratory birds are a shared natural heritage (遗产), and with this comes a common {#blank#}10{#/blank#} (responsible) to protect them and the places they need," he says.
