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.

54. 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.

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

A. B. C. D.

Try and see inside your mind a wide open blue sky and a wide green sea far away. Breathe in as you circle your hands high above your head, then bend back a little. Breathe out as you circle your arms back down to your sides..."
Following the yoga teacher's gentle instructions, Bai Yunuo,15, from the High School attached to Beijing Normal University tried to get each of her poses correct.
Bai's school offered 24 elective courses (选修课) for Senor 1 students this term and she chose two. It was her first yoga class.
"I'm happy that I can learn yoga at school. I love dancing but I had some injuries on my knees when I was a kid. So I decide to try something soft. Simply stretching into different poses makes me feel free and quiet. And the music is quite comforting. The class is relaxing after a whole day's work," Bai said.
Liu Zehao,15, found his interest was Junior Achievement (企业经营模拟). The course brought students into the real world of business. In their first class, Liu and his group members named their company "Vision". Liu was elected as CEO of the company.
"Here we learn to think like an adult. We have to make our company get more money. It's new and different from other courses," he said.
Liu and Bai take their elective courses twice a week with students from other classes who share the same interest. The students will get two credits (学分) from each course at the end of this term. They have to achieve eight credit points from electives to graduate from high school.

【小题4】Where can you possibly find this passage?

Home to me means a sense of familiarity and nostalgia(怀旧). It's fun to come home. It looks the same. It smells the same. You'll realize what's changed is you. Home is where we ran remember pain, live, and some other experiences; We parted here; My parents met here; I won three championships here.
If I close my eyes, I can still have a clear picture in mind of my first home. I walk in the door and see a brown sofa surrounding a low glass-top wooden table. To the right of the living room is my first bedroom. It's empty, but it's where my earliest memories are.
There is the dining room table where I celebrated birthdays, and where I cried on Halloween-when I didn't want to wear the skirt my mother made for me. I always liked standing on that table because it made me feel tall and strong. If I sit at this table, I can see my favorite room in the house, my parents' room. It is simple: a brown wooden dresser lines the right side of the wall next to a television and a couple of photos of my grandparents on each side. Their bed is my safe zone. I can jump on it anytime - waking up my parents if I am scared or if I have an important announcement that cannot wait until the morning.
I'm lucky because I know my first home still exists. It exists in my mind and heart, on a physical property(住宅) on West 64th street on the western edge of Los Angeles. It is proof I lived, I grew and I learned.
Sometimes when I feel lost, I lie down and shut my eyes, and I go home. I know it's where I'll find my family, my dogs, and my belongings. I purposely leave the window open at night because I know I'll be blamed by Mom. But I don't mind, because I want to hear her say my name, which reminds me I'm home.

Researchers at San Diego Zoo have been studying what has been described as the “secret language” of elephants. They have been monitoring（监测） communications between animals that cannot be heard by human ears.
The elephant’s call will be familiar to most people, but the animals also give out growls (低吼). Their growls, however, are only partly audible (听得见的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”
The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation (妊娠期) of over two years, in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,” said Dr Anderson.
The researchers believe that this also warns the elephants to look out for coming danger. “You may think that a baby calf of about 300 pounds would not be as open to predation (捕食) as other species,” he says. “But packs of hyenas (袋狼) are a big threat in the wild.”
Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.
【小题1】Why some elephants’ call is called “secret language”?

A．Because it can’t be heard by human ears.

B．Because it can only be heard by female elephants.

C．Because people don’t know its meanings.

D．Because people haven’t studied it completely.

【小题2】By using a sensitive microphone and a GPS tracking system, the researchers wanted to find out .

A．where the elephants usually go

B．what the elephants’ growls really mean

C．how mother elephants raise baby calves

D．how elephants protect their babies.

【小题3】A pregnant elephant uses inaudible growls to .

A．show the location where she is staying

B．ask for help when she losses her way
