Last week, we explained that the planet Mars had passed “opposition.” It passed a point opposite the Sun. This week, we tell about the planet’s surprising motion among the stars.
For thousands of years, people have recognized that planets travel among the stars. The planets generally follow the path taken by the Sun through the sky. The Sun’s path is called the ecliptic. The groups of stars along the ecliptic are called the Zodiac(黄道带).
The motion of the planets can be confusing at times. Everyone knows the Sun rises in the east and sets in the west. But this is caused by the turning motion of the Earth. Planets generally move from west to east.
However, Mars will appear to move backward for about two months this year. This happens because the Earth is overtaking Mars on its way around the Sun. Mars began its backward, or westward, motion on May 11th. It will start moving eastward again on July 19th.
Mars’ apparent motion has been a mystery to astronomers for hundreds of years. Most early theories of tilt solar system argued that the Sun and planets turned around the Earth. But the sudden westward motion of Mars presented problem. Why would Mars move west for two months when it nears “opposition”?
In 1543, a Polish church worker named Nicolas Copernicus published a different theory. His theory said the Earth and planets moved around the Sun in perfectly circular orbits. Copernicus’ theory was simpler. But his Sun-centered system still did not explain the observed motion of Mars very well.
Finally, a German mathematician named Johannes Kepler published a complete theory of the motion of the planets in 1619. He had carefully studied the motion of Mars for many years.
Johannes Kepler discovered that the planets do not move in circular orbits around the Sun. Instead, they travel in flattened orbits called ellipses(椭圆). Mars’ elliptical orbit is the cause of its unusual brightening this year and its apparent large size.
During the next several weeks, you can see for yourself why the mysterious motion of Mars has caused so many people to wonder.

We've reached a strange-some would say unusual-point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization (WHO), more people now die from being overweight, or say, from being extremely fat, than from being underweight. It's the good life that's more likely to kill us these days.
Worse, nearly l8 million children under the age of five around the world are estimated to be overweight. What's going on?
We really don't have many excuses for our weight problems. The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through-up to a point.
In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public-health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades.
Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world's most body-conscious country.
We know what we should be doing to lose weight-but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower.
Others blame good food. They say: it's just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American-style fast food.
Some also blame their parents-their genes. But unfortunately, the parents are wronged because they're normal in shape, or rather slim.
It's a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say-not as I do.

Mothers and daughters go through so much—yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother, Sheila Solomon Klass, both gifted professional writers, prove to be ideal co-writers as they examine their decades of motherhood, daughterhood, and the wonderful ways their lives have overlapped (重叠).
Perri notes with amazement how closely her own life has mirrored her mother’s: both have full-time careers； both have published books, articles, and stories； each has three children； they both love to read. They also love to travel—in fact, they often take trips together. But in truth, the harder they look at their lives, the more they acknowledge their big differences in circumstance and basic nature.
A child of the Depression (大萧条), Sheila was raised in Brooklyn by parents who considered education a luxury for girls. Starting with her college education, she has fought for everything she’s ever accomplished. Perri, on the other hand, grew up privileged in the New Jersey suburbs of the 1960s and 1970s. For Sheila, wasting time or money is a crime, and luxury is unthinkable while Perri enjoys the occasional small luxury, but has not been successful at trying to persuade her mother into enjoying even the tiniest thing she likes.
Each writing in her own unmistakable voice, Perri and Sheila take turns exploring the joys and pains, the love and bitterness, the minor troubles and lasting respect that have always bonded them together. Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork. Perri admits that she can’t sort out all the mess in the households, even though she knows it drives her mother crazy. Together they compare thoughts on bringing up children and working, admit long-hidden sorrows, and enjoy precious memories.
Looking deep into the lives they have lived separately and together, Perri and Sheila tell their mother-daughter story with honesty, humor, enthusiasm, and admiration for each other. A written account in two voices, Every Mother Is a Daughter is a duet (二重奏) that produces a deep, strong sound with the experiences that all mothers and daughters will recognize.Why does Perri think that her own life has mirrored her mother’s?
| A．They both have gone through difficult times. |
| B．They have strong emotional ties with each other. |
| C．They have the same joys and pains, and love and bitterness. |

Some years ago, writing in my diary used to be a usual activity. I would return from school and spend the expected half hour recording the day’s events, feelings, and impressions in my little blue diary. I did not really need to express my emotions by way of words, but I gained a certain satisfaction from seeing my experiences forever recorded on paper. After all, isn’t accumulating memories a way of preserving the past?
When I was thirteen years old, I went on a long journey on foot in a great valley, well-equipped with pens, a diary, and a camera. During the trip, I was busy recording every incident, name and place I came across. I felt proud to be spending my time productively, dutifully preserving for future generations a detailed description of my travels. On my last night there, I wandered out of my tent, diary in hand. The sky was clear and lit by the glare of the moon, and the walls of the valley looked threatening behind their screen of shadows. I automatically took out my pen…
At that point, I understood that nothing I wrote could ever match or replace the few seconds I allowed myself to experience the dramatic beauty of the valley. All I remembered of the previous few days were the dull characterizations I had set down in my diary.
Now, I only write in my diary when I need to write down a special thought or feeling. I still love to record ideas and quotations that strike me in books, or observations that are particularly meaningful. I take pictures, but not very often—only of objects I find really beautiful. I’m no longer blindly satisfied with having something to remember when I grow old. I realize that life will simply pass me by if I stay behind the camera, busy preserving the present so as to live it in the future.
I don’t want to wake up one day and have nothing but a pile of pictures and notes. Maybe I won’t have as many exact representations of people and places； maybe I’ll forget certain facts, but at least the experiences will always remain inside me. I don’t live to make memories—I just live, and the memories form themselves.Before the age of thirteen, the author regarded keeping a diary as a way of ______.
| A．observing her school routine | B．expressing her satisfaction |

About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled(注册) my son in kindergarten. Several weeks later, my son’s teacher asked me to meet him at his office.
In the teacher’s office, and exchange of greetings was followed by his questions: “Is your son mentally retarded(弱智的)？Does he suffer from any kind of mental disability?”
Was he talking about my wonderful Scola? NO, no, it can’t be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.
My son could not follow the teacher’s directions, he told me, and thus, Scola was disrupting the class, Didn’t he know my son did not speak English yet?
He was angry; “Why hasn’t your son been taught to speak English? Don’t you speak English at home?”
No, I didn’t speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn't want him to forget his native language. Well, wrong answer! What kind of person would not speak in English to her son at home and at all time? “Are you one of those people who come to this country to save dollars and send them back to their country, never wanting to be a part of this society?”
Needless to say, I tried to tell him I was not one of “those people.” Then he told me the meeting was over, and I left.
As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual(双语的)。
Speaking more than one language allows people to communicate with others;it teaches people about other cultures and other places—something very basic and obviously lacking in the “educator” I met in New Jersey.The teacher asked the author to his office__________.
| A．to discuss Scola’s in-class performance |
| B．to get Scola enrolled in kindergarten |

The author’s attitude towards being bilingual may best be described as__________.
| A．critical | B．casual | C．positive | D．passive |
This text is likely to be selected from a book of _________.
| A．medicine | B．education | C．geography | D．history |
According to sociologists(社会学家), every modern industrial society has some form of social stratification(阶层). Class, power and status are important in deciding people’s rank in society.
Class means a person’s economic position in society. A commonly used classification is lower class, middle class and upper class. While sociologists disagree on how these terms should be exactly defined, they do describe societies like the United States quite well. One study shows that 53% of Americans belong to the lower class, 46% the middle class, and 1% the upper class. Interestingly, a surgeon earning ＄500,000 a year and a bus driver earning ＄50,000 a year both regard themselves as the middle class!
Power refers to the amount of control a person has over other people. Obviously, people in positions of great power (such as governors) exercise(行使)big power, but people who take orders from others have less power. Power and class do not always go hand in hand, however. For example, the governor of a state has great power, but he or she may not belong to a corresponding (相应的)economic class. Generally, however, there is a relationship between power and class.
To our knowledge, there aren’t too many people who aren’t millionaires in the U.S. Senate!
Status is the honor or respect attached to a person’s position in society. It can also be affected by power and class, but not necessarily so. For example, a university professor may have a high status but not belong to a high social class or have a lot of power over others.What can we learn about “the middle class” from Paragraph 2?
| A．People earning ＄50,000 a year belong to the middle class. |
| B．Nearly half Americans belong to the middle class. |
| C．People generally consider bus drivers as the middle class. |
| D．Sociologists have a clear definition of the middle class. |
According to the text, we know that _____.
| A．power and class do not always correspond with each other |
| B．status refers to a person’s economic position in society |
| C．people with high status have a lot of control over others |
| D．class is less important in deciding a person’s social rank |
