{#blank#}1{#/blank#} When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, visions of country clubs dance into view.

    The many wants of mankind might be regarded as making up several levels. {#blank#}2{#/blank#}.

    The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. {#blank#}3{#/blank#} It included such items as cars and new houses.

    By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction－the feeding, comfort, safety, and transportation of the human body－this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items(奢侈品). Among them are vacation trips, the best medical care, and entertainment. {#blank#}4{#/blank#}

    On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?

    A fifth level probably would be wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. {#blank#}5{#/blank#} In this way, we can enjoy more fully the good things on the first four levels.

 A．Then a third level appeared.

 B．Human wants seem endless.

 C．When there is money enough to satisfy one level of wants, another level appears.

 D．There are several levels of wants in one's life.

 E．At this stage, we now may seek to ensure the health, safety, and leisure.

 F．Also included here are fancy foods and the latest styles in clothing.

 G．Different people have different wants on each level 

    Hello, Listeners. Welcome to Henton Hospital Radio. Before our music program at four, I'm going to repeat some of our hospital rules.

    The hospital can sleep 800 patients. There're 8 beds in each ward (病房). The visiting hours are in the afternoon from 2:30 to 3:30 and in the evening from 7:00 to 8:00. But remember only two people can see you at the same time. Sorry about that, but you can see what would happen if we didn't have these rules.

The other rules are about our hours. We start quite early—you might not be used to that. We wake you at 6 o'clock, and breakfast is at 8 o'clock, lunch is at noon.

    There's tea at 3:30 and supper is at 6 o'clock.

    You can see the non-smoking sign –-- we don't allow smoking in the wards. I'm sure you understand why. However, if you do need to smoke, there are some smoking rooms where it is allowed.

    You will find the radio switch (开关) on the wall near your bed, with your own headphones, if you want to listen. It's our own hospital radio wishing you a quick recovery (康复).

    For years,Hagelin has studied what role scents（气味）play in wild birds' behavior.In 2010,Hagelin heard Jan Straley,a marine biologist,talk about the behavior of whales.Straley mentioned that whales often leap into the air,but nobody knew why.

    The mystery interested Hagelin.So Hagelin asked Straley whether they might leap to smell the air—maybe to locate food or look for danger.Straley replied that it was an interesting idea but there wasn't much evidence that whales have a sense of smell.To investigate the idea further,the two scientists teamed up.

    In the summer of 2011,they set up a post on the coast of southern Alaska.The researchers spent hours monitoring the direction of the whales and of the wind.The whales headed into the wind half of the time.This didn't prove that whales leap to smell,but it suggested that it is possible.

    Meanwhile,other researchers in Alaska were studying a region of the brain called the olfactory bulb（嗅觉球）in whales.Olfaction means the ability to smell.Humans also process smells in the olfactory bulb.

    In identifying a scent,you might think the nose does all of the work.However,the major role of a nose is to draw chemicals on the air and pass them across sensing cells.As chemicals come into contact,they give signals that travel directly to the bulb and then in the brain for further interpretation.

    The researchers discovered that the bulb in a whale was more complex than the one in a human.In whales,this smell-processing center takes up a share of the brain six times larger than it does in humans.

    The brain research suggested that whales probably can smell just as well as people—and possibly better than humans can.It is supposed that a good sense of smell could help them find food more easily.

    However,Hagelin is not sure of that.Now he is planning a new study that will examine whether whales do use the sense of smell to find food.

    What makes a building ugly? Everyone's got their own opinion, so it's hard to say. Now, let's take a look at some of the world's worst buildings.

    The Torre Velasca

    The Tone Velasca in Milan is in the centre of Milan (Italy). The tower, which went up in the 1950s, is about 100 metres tall. Its design is actually a modern representation of a traditional Lombard castle, where the lower parts were narrower (狭窄的）than the upper parts.

    The Mirador Building

    The Mirador Building in Madrid (Spain) was created by Dutch studio MVRDV and the Spanish architect Blanca Lleo. The building, which is a block of flats, opened in 2005. There is a large rectangular (矩形的）hole in the upper part of it, which is used by the neighbourhood as a meeting area and playground.

    The Prague TV Tower

    The Prague TV Tower is in Prague (the capital of the Czech Republic). It stands 216 metres high and looks a bit like a tall, thin space ship. Prague is famous for its architectural beauty,so when the tower was put up in 1985 by architect Vaclav Aulicky and engineer Jiri Kozak, many felt it didn't fit in.

    The Longaberger Basket Company

    The Longaberger Basket Company building is in Newark, Ohio (USA). The office block was opened in 1997 and looks like a very large basket. It，s got seven floors and two handles at the top. The handles weigh about 150 tons. It may not be the ugliest building in the world but it's certainly one of the most unusual.

It is believed that Chinese knotting, also known as zhongguojie, originated for recording information and exchanging messages {#blank#}1{#/blank#} writing was invented. Over the past thousands of years, knots {#blank#}2{#/blank#} (play) an important part in the life of Chinese. {#blank#}3{#/blank#} (initial), Chinese knots acted as good -luck charms to drive away evil spirits. Today, Chinese knots are widely used to decorate homes during festivities.

A major characteristic of Chinese knots is that they are often tied from a single continuous length of string. The knots are commonly named {#blank#}4{#/blank#} the shape it takes. Chinese knots are created in a {#blank#}5{#/blank#} (various) of colors such as gold, green, blue, or black, though the most commonly used color is red, {#blank#}6{#/blank#} symbolizes good luck and prosperity.

Crafting the Chinese knot is a three-step process {#blank#}7{#/blank#} (involve) tying knots, tightening them and adding the finishing touches. The knots {#blank#}8{#/blank#} (pull) tightly together and are strong enough to be used for binding or wrapping, making them very practical.

Today, most of such knots are often mass manufactured in factories. Skilled knot artists weave complex knots that you might see {#blank#}9{#/blank#} (sell) as souvenirs that you can take back with you. If you have time, why not try your hand at it? Perhaps these age-old charms can add {#blank#}10{#/blank#} touch of good luck to your daily life?
