听力原文： Currency options may have two kinds of value, intrinsic value and time value. If and to the extent that an option would currently be profitable to exercise, it is said to have intrinsic value. In the case of a call, if the spot price is higher than the option exercise price, the option has intrinsic value. In the case of a put, if the spot price is less than the option exercise price, the option has intrinsic value. Such options are said to bein-the-money'. If the opposite is true of either calls or puts, they have no intrinsic value and said to be out-of-the-money'.

The power of words, then, lies in their associations - the things they bring up before our minds.Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions.This charming and telling use of words is what we call literary style.Above all, the real poet is a master of words.He can convey his meaning in words which sing like music and which by their position and association can move men to tears.We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar .(239words)

What is it about a dog's gaze that makes it so charming？ A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.
The cuddle chemical has another, more scientific name: oxytocin.Oxytocin is a substance in the blood that encourages bonding.Levels of oxytocin increase, for example, when a mother feeds her newborn baby.According to Nagasawa's study, the same is true when we look deeply into the eyes of a dog.
The results of this study can tell us a lot about the history of the bond between humans and dogs.It all started somewhere tens of thousands of years ago.Scientists believe that wolves used to follow humans who were hunting large animals.The wolves would eat the food left behind by the humans.
Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.
Over time, the wolves that interacted with the humans began to change.They became more loyal to their human partners.The wolves and humans started to depend on each other and bond with each other.These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie evolved to better survive in their environment.
This process depended a great deal on the bond humans formed with them.And according to Nagasawa's study, this bond was formed with the help of oxytocin, the cuddle chemical.
11.What do we know about oxytocin？()
A.It regulates blood flow
B.It promotes bonding

D.It is good for health
12.When we look deeply into a dog's eyes, the levels of our oxytocin ____.

C.take humans for food
D.hunt large animals together
14.Over time some wolves turned into dogs ____.
A.due to their loyalty
B.due to the changing environment
C.for better survival
D.for better cooperation
15.What does Nagasawa9s study aim to do？()
A.Explore the role of human-wolf partnership
B.Show the characteristics of the cuddle chemical
C.Explain the bond between humans and dogs
D.Understand the evolution of species
I have learned something about myself since I moved from Long Island to Florida three years ago. Even though I own a home in Port St. Lucie just minutes from the ocean, an uncontrollable urge wells up to return to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse. Instead of enjoying Florida’s mild winters, I willingly endure the severe weather on Long Island, the place I called home for 65 years.
I’m like a migratory bird that has lost its sense of timing and direction, my wings flapping against season.
So what makes me fly against the tide of snowbirds？ The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display o￡ colors — first in the fall trees, and then in the limits around homes and at Rockefeller Center. Floridians decorate too, but can’t create the special feel of a New England winter.
I suppose the biggest reason why I return is to celebrate the holidays with people I haven’t seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors’ children excitedly open gifts on Christmas？ Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch (My wife and I spend winters at a retirement community in Ridge, and I’m grateful that I don’t have to shovel.)
While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can’t go home？

Take a second long piece of paper. Twist the paper once and glue the ends together. Now you have made a Mobius band(带子). For people studying maths, this band is uncommon.
This strange band was first made in the 1800s by a German man namedAugust. Mobius. Mr. Mobius studied maths. He wanted to find a way to show how this band works with maths. Understand it or not, this band has only one surface. You can find this out for yourself.
If you draw a line on the surface of the paper before you twist and glue it, the line is only on one side of the paper. The paper has two surfaces. However, if you draw a line after you make the Mobius band, you can follow the line around all sides of the paper. In other words, the Mobius band must have only one surface.
It is also very interesting to see what happens when you cut the band. If you cut the Mobius band in half once down the line you drew, you do not get two Mobius bands. Instead, after you cut the band, it turns into one large twisted ring. Then, if you cut this ring in half along the middle of the band again, you get two connected(相连的)Mobius bands.

In the United States, people greet each other with a handshake in a formal introduction. The handshake must be firm. If the handshake is weak, it is a sign of weakness or unfriendliness. Friends may place a hand on the other’s arm or shoulder. Some people, usually women, greet a friend with a hug.
Space is important to Americans. When two people talk to each other, they usually stand about two and a half feet away and at an angle, so they are not facing each other directly. Americans get uncomfortable when a person stands too close. They will move back to have their space. If Americans touch another person by accident, they say “Pardon me” or “Excuse me”.
Americans like to look the other person in the eye when they are talking. If you don’t do so, it means you are bored, hiding something, or are not interested. But when you stare at someone, it is not polite.

Examples of public goods are not as rare as one might expect.A flood control dam is a public good.Once the dam is built, all persons living in the area will benefit------irrespective of their own contribution to the construction cost of the dam.The same holds true for highway signs or aids to navigation.Once a lighthouse is built, no ship of any nationality can be effectively excluded from the utilization of the lighthouse for navigational purposes.National defense is another example.Even a person who voted against military expenditures or did not pay any taxes will benefit from the protection afforded.
It is no easy task to determine the social costs and social benefits associated with a public good.There is no practicable way of charging drivers for looking at highway signs, sailors for watching a lighthouse and citizens for the security provided to them through national defense.Because the market does not provide the necessary signals, economic analysis has to be substituted for the impersonal judgement of the marketplace.
