Sometimes we cry because we are sad and sometimes because we are extremely happy.An irritant(刺激物),such as onion(洋葱) smell or grains of sand in the eye,can also make cry.In this case tears perform an obvious role in getting rid of substances that might harm the surface of the eye.
Dr.William Frey of the Dry Eye and Tear Research Center at St.Paul in Minnesota,USA,believes that tears from emotional causes may perform a similar role.He thinks that crying could get rid of emotional stress by washing away a chemical in the blood caused by strong emotions. To prove his theory, he hopes first to identify this chemical and then see if it is found in tears of sadness or happiness.
So far, Dr.Frey has failed to find out the difference between emotional tears and tears caused by an irritant in the eye.This may be because these substances themselves cause a degree of stress and emotion.What he has identified in all tears is a variety of biochemicals(生化物)which are one of the causes of stress.A more detailed study may help us understand why sufferers from stress-related disorders cry less often than healthy people.Dr.Frey is also very interested to see if there are any physiological(生理学的)explanations for why women,in general,cry five times more often than men,on average.

I decided to go back to school in the fall of 2008 after not being happy with my current job and financial status. I obtained my Associate’s Degree in May 2002 in Commercial Arts. After graduation, I had trouble obtaining a job in that field. For years, I was going from one job to another feeling unfilled, and I was not satisfied with the instability.
I decided to go back to school for either International Business or Psychology. I weighed the pros and cons of both professions and Psychology won. I like helping my friends and family, when they go through hard situations in their life by giving them sound advice and being honest with them. Also, I was interested in “the mind”.
I was searching for online schools because my work schedule at my current job would not allow me to attend a regular class. I was nervous about starting online classes because I heard mixed stories from other friends who were taking online classes. I decided to do it anyway to experience something different. I wanted to find an online school that was affordable and reputable. Through my search, I discovered Walden University, which is specially for working adults who want to obtain a bachelor’s degree or higher. The process of getting accepted was easy, which included writing an essay on why I wanted to attend their school, transferring my previous credits, etc.
I am currently enrolled in the Bachelors program for psychology, and I am paying for college via financial-aid loans and grants. This experience has been interesting yet trying as sometimes it was difficult to balance work, school and home life. I learned a lot about psychology and myself. For example, I like writing about current events, relationships and traveling. I thought my English composition was ordinary, but after taking a few classes at Walden University, I improved my English composition and it made me feel confident enough to start writing professionally so I became a freelance (自由撰稿) writer. Currently, I am only three classes away from obtaining my Bachelor’s Degree in Psychology! It was one of the best decisions I made in my life.What did the author study originally when he was in college?

Looking out of the window, my son saw a tree whose branches were strongly swaying back and forth. “How does the tree move its branches like that?” He asked.
Without rising from my chair, nor looking up from my book, I started to answer, “The tree is not moving the branches, son. The wind is…” But before the words were out, I caught myself. Instead I rose from my chair and moved to the window to join my son. I looked at the tree. From inside our room, from behind the window, I could neither feel nor hear the wind. I saw instead a tree with its branches silently moving and thought to myself, from inside this room, how could I possibly be sure that the branches were moving because of the wind rather than from the tree’s own willing?
As I stood there with my son watching the tree, I became struck by the movement of the branches, the shimmer of the leaves. My mind quieted and I became less sure myself of what was causing the branches to move. Was it the wind, or was it some expressive, independent movement of the tree? “I see what you mean,” I said to my son. “The movement of the tree is very beautiful.”
“Do you think the tree is dancing?” asked my son. “Why would it be dancing?” I asked. “Maybe it is happy because the sun is shining,” he said. “Perhaps,” I said. “Or because it’s spring,” he added, “and it’s not cold any more.” “Perhaps,” I said.
As we continued to watch the tree together, I, too, began to appreciate the dance of the tree. I enjoyed the movement and sway of the branches, seeing little nuances(微妙之处) that I hadn’t noticed before. There seemed to be a rhythm to the movement, first strong and forceful, then light and gentle, then more vigorous, sometimes nearly violent.
“Are trees alive?” my son asked. “Yes, they are alive. Why do you ask?” “Because this tree looks happy,” he answered. “Can a tree be happy or sad?” “What do you mean?” I asked.
“In the winter, trees seem sad,” he said. “Their branches hang down, and they look cold and lonely. But now with the leaves on the tree and the sun shining and the birds flying, it looks happy.”What is the meaning of the underlined word “caught” in Para 2?
A.stopped | B.grasped | C.seized | D.held |
What on earth caused the tree to move?
A.The tree itself felt happy and was dancing. |
B.The tree was too sad to sway as if to get rid of all trouble. |
C.It was the warm spring. |
D.The wind did so. |
What do you think of the boy?
A.Naughty. | B.Imaginative. | C.Clever. | D.Foolish. |
Informal conversation is an important part of any business relationship.Before you start a discussion,however,make sure you understand which topics are suitable and which are considered taboo(禁忌)in a particular culture. Latin Americans enjoy sharing information about their local history, art and customs.You may expect questions about your family,and be sure to show pictures of your children.You may feel free to ask similar questions of your Latin American friends.The French think of conversation as an art form,and they enjoy the value of lively discussions as well as disagreements. For them,arguments can be interesting and they can cover pretty much or any topic ---- as long as they occur in are respectful and intelligent manner.
In the United States,business people like to discuss a wide range of topics,including opinions about work,family,hobbies,and politics. In Japan,China,and Korea,however,people are much more private.They do not share much about their thoughts,feelings,or emotions because they feel that doing so might take away from the harmonious business relationship they’re trying to build.Middle Easterners are also private about their personal lives and family matters.It is considered rude,for example,to ask a businessman from Saudi Arabia about his wife or children.
As a general rule,it’s best not to talk about politics or religion with your business friends.This can get you into trouble,even in the United States,where people hold different religious views.In addition,discussing one’s salary is usually considered unsuitable.Sports is typically a friendly subject in most parts of the world,although be careful not to criticize national sport.Instead,be friendly and praise your host’s team.The author considers politics and religion ___________.

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affect sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels(分贝)measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.According to the passage, which of the following is increasingly dangerous to sea creatures?
A.The man-made noises. |
B.The noises made by themselves. |
C.The sound of earthquakes. |
D.The sound of the ice-breaking. |
As to the influence of noises on whales, which of the following statements is true?
A.They are deaf to noises. |
B.Noises at a certain level may hurt them. |
C.They are easily confused by noises. |
D.Noises will limit their ability to reproduce. |
We can know from the passage that many scientists think that the noise limit of one hundred twenty decibels would______.
A.prevent them from doing their research work |
B.benefit them a lot in their research work |
C.do good to their health |
D.increase the industrial output |
According to the passage, what will scientists most probably do in the future?
A.They will try their best to decrease noise. |
B.They will work hard to cut down noise pollution. |
C.They will study the effect of different noises. |
D.They will protect animals from harmful noises. |
Many a young person tells me he wants to be a writer. I always encourage such people,but I also explain that there's a big difference between “being a writer” and writing.In most cases these people are dreaming of wealth and fame, not the long hours alone at a typewriter. “You've got to want to write, ”I say to them, “not want to be a writer”.
The reality is that writing is a lonely, private and poor-paying affair. For every writer kissed by fortune there are thousands more whose longing is never rewarded. When I left a 20-year career in the U.S. Coat Guard to become a freelance writer, I had no hope at all.What I did have was a friend who found me a room in a New York apartment building.It didn't even matter that it was cold and had no bathroom.I immediately bought a used typewriter and felt like a real writer.
After a year or so.However, I still hadn't gotten a break and began to doubt myself.It was so hard to sell a story that I hardly made enough to eat.But I knew I wanted to write,l had dreamed about it for years.I wasn't going to be one of those people who die wondering, what if? I would keep putting my dream to the test—even though it meant living with uncertainty and fear of failure.This is the shadow land of hope,and anyone with a dream must learn to live there.The purpose of the passage is to.
A.warn young people of the hardships that a successful writer has to experience |
B.advise young people to give up their idea of becoming a professional writer |
C.show young people it's unrealistic for a writer to seek wealth and fame |
