The “babies” tend to be on or near me, or crying, or both. I spend a fair amount of time trying to get William to sleep, to get Elliott to get involved in something that will actually keep him happy for a little while, or to get William to play on the floor for 10 minutes straight so that I can get something done. But, a lot of days, it seems like I'm not succeeding in any of those efforts.

    So, yesterday, a friend of mine posted a picture on Facebook. This particular friend has a baby who is about a month younger than William. The picture was of the baby, who had made his way across the floor to the toys housed along the side of the room. I just kept looking at that picture and thinking that if only William had some different toys to play with, perhaps he would stay occupied a bit longer at a stretch. But William seems so bored with all of his toys! And I am so ready for him to be ready to play. In order to find a way to make him playing longer, I kept looking at that picture. Suddenly, I realized my sons need to play closer to me.

    So I cleared off the cubby(围起来的)shelves in the playroom, and my husband and I moved it to the living room. We found all of the toys that would be safe for William and put them in the cubbies. Then, we pulled the play kitchen in.

    William was so interested in what I was doing that he sat there and played and chewed on his toys while we moved furniture. When we were done, I moved him over closer to the cubbies and he got so excited that he didn't disturb for an hour, while I made dinner and cleaned up! Even Elliott played happily for a few hours. It was a dream come true! And I got to know that my lack of happy children was because of my desire for a toy—free living room.

    Energy independence. It has a nice ring to it. Doesn't it? If you think so, you're not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession.

    “Energy independence” and its rhetorical (修辞的) companion “energy security” are, however, slippery concepts that are rarely though through. What is it we want independence from, exactly?

    Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that oil from elsewhere.

    The first reason is that we need it to keep our economy running. Yes, there is a trickle（涓涓细流）of biofuel available, and more may become available, but most biofuels cause economic waste and environmental destruction.

    Second, Americans have basically decided that they don't really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits(禁止) to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?

    Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don't read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.

    There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices, At the same time, we derive(得到，获得) massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.

    When I was young I wanted to be a model,so when a national contest was staged,I convinced my parents to have a try.I was selected and told that I was talented and that for only $900 I could attend a weekend event which dozens of the most famous modeling agencies from around the world would attend.At 13,my hopes of fame and fortune clouded all judgment and I begged my parents to let me go.We have never been rich,but they saw my enthusiasm and agreed.

    I imagined being signed by some famous model companies.For months,any boredom or disappointment I faced was pushed aside because I knew I would soon have the chance to be a real model.I thought I would grace the covers of famous magazines!

    Of course,I wasn't signed,but what hurt the most was being told that if I grew to about 1.75metres I could be a success.I prayed for a growth spurt（冲刺）because I could not imagine giving up my dream.I made an appointment with a local modeling agency and the agent demanded $500 for classes,$500 for a photo shoot,and $300 for other expenses.My parents only agreed after hours and hours of my begging.

    The agency sent me out on a few auditions,but with every clay I didn't receive a call,I grew more depressed.The final straw came in July after I had decided to focus on commercial modeling.There was an open call in New York City.We spent hours driving and another few hours waiting,only to be told that I was too short.I was depressed.

    Years later,I realized that the trip to New York was good as it made me notice I didn't actually love modeling, just the idea of it.I wanted to be special and I was innocently determined to reach an impossible goal.The experience has made me stronger and that will help me in the future.

    Now many young people are traveling around the world on their own，not because they have no one to travel with，but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries，with no one to help you read a map，look after you if you get ill，or lend you money if your wallet is stolen，it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website，The Aussie Nomad，to document his adventures. He says he wished he had traveled alone earlier. “The people you meet，the places you visit，or the things you do，everything is up to you and it forces you to grow as a person，” said the 30-year-old man.

    Richardson describes traveling alone like "a shot in the arm"，which "makes you a more confident person that is ready to deal with anything". He said，"The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19th century explorer John Muir once said，"Only by going alone in silence can one truly get into the heart of the wilderness."

    The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or m, however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother" the real mother or the mother-substitute(母亲替代).

    During the first two weeks of its life warmth is perhaps the most important psychological(心理的)thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother substitutes one covered with cloth 4nd one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their fuvorites. Thereafter they switched and spent most of their time on the mw comfortable cloth mother.

    Why is cloth preferable to bare wire? Something that the Harlows called contact(触摸)comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire doesn't “rub" as well as does soft cloth. Prolonged(长时间的)“contact comfort" with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk.

    According to the Harlows, the basic quality of baby's love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no nutter how interesting they might be. It screams in terror and curls up into a furry little ball. If its cloth mother it now introduced into the playroom, the baby rushed to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. it then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace(拥抱)as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its “mother.”

During China's dynastic period, emperors planned the city of Beijing {#blank#}1{#/blank#} arranged the residential areas according to social classes. The term "hutong", {#blank#}2{#/blank#} (original) meaning "water well" in Mongolian, appeared first during the Yuan Dynasty.

In the Ming Dynasty, the center was the Forbidden City, {#blank#}3{#/blank#} (surround) in concentric (同心的) circles by the Inner City and Outer City. Citizens of higher social classes {#blank#}4{#/blank#} (permit) to live closer to the center of the circles. The large siheyuan of these high-ranking officials and wealthy businessmen often {#blank#}5{#/blank#} (feature) beautifully carved and painted roof beams and pillars (柱子). The hutongs they formed were orderly, lined by {#blank#}6{#/blank#} (space) homes and walled gardens. Farther from the center lived the commoners and laborers. Their siheyuan were far smaller in scale and {#blank#}7{#/blank#} (simple) in design and decoration, and the hutongs were narrower.
