What affects our self-esteem(自尊)?

Puberty(青春期)and development. Some people struggle with their self-esteem and body image when they begin puberty.  36  These changes, combined with wanting to feel accepted by our friends, mean it can make us want to compare ourselves with others. The trouble with that is, not everyone grows or develops at the same time or in the same way.

Media images and other outside influences. Our early teens are a time when we become more aware of celebrities (名人) and media images as well as how other kids look and how we fit in with others.  37  All of this can affect how we feel about ourselves and our bodies even as we grow into our teens.

Families and schools. Family-life can sometimes influence our body images.  38 Family members might struggle with their own body image or criticize their kids’ looks. This can all influence a person’s self-esteem, especially if they’re sensitive to others’ comments, even their classmates.  39 Although these often come from ignorance, sometimes they can affect body images and self-esteem.

Healthy self-esteem. If you have a positive body image, you probably like and accept yourself the way you are, even if you don’t fit some media ideals. This healthy attitude allows you to explore other aspects of growing up, such as developing good friendships, becoming more independent, and challenging yourself physically and mentally.  40

A. Friendship is important to our school life.

B. It’s a time when the body goes through many changes.

C. Teens may experience many problems when growing up.

D. Some parents might be too focused on looking a certain way.

E. Developing these parts of yourself can help improve your self-esteem.

F. We might start to compare ourselves with other people or media images.

G. People may also experience negative comments about the way they look from classmates.

Movie Extras

Would you mind lying in a coffin(棺材)?Would you shave your head? Are you willing to take out your false teeth?

These are just a few of the questions Anne Marie Stewart and her staff sometimes ask the “talent” who serve as non-speaking “extras” in special films, television series, and made-for-TV movies produced in Toronto.

Of course, the majority of extra calls are for more ordinary people, and Stewart has a list of about 650 registered extras. Crowd scenes, which are common, call for everyday people of all ages, ethnic backgrounds, and sizes.

Over at Movie People, last-minute requests are not unusual. “We got a request once for an entire brass band of 30 people. They wanted it within the hour,” said manager Yvonne McCartney. Another time, the company got a last-minute request for a newborn baby. “We found a baby that was three weeks premature,” said Jonathan Aiken, an owner of the company.

Then there was the worried call from a casting director whose “Star” got doggone stubborn one day and decided to just lie down and not work. The director needed a replacement dog, fast. “We got them two in one hour,” said Aiken, “It was a matter of good connections and fast phone work.” The eight phone lines needed to make 350 to 400 calls a day are one of Movie People’s major expenses.

Phone lines are the only way to stay in touch with casting directors and extras, but the latter are a group not necessarily interested in a long-term relationship. Most extra jobs pay only 7 dollars an hour(with a minimum of six hours),while most agencies charge an annual 75 dollars)registration fee and get 10 to 15 per cent of extras’ earnings. It’s no wonder that the turnover rate is fairly high.

Some people who are between jobs do extra work as a temporary measure, said McCartney. But professionals, such as lawyers, also do the work, because it’s interesting. Others with flexible jobs have a desire to do something different. Some homemakers want to get out of the house and onto a movie set. Money’s not the motivating reason.

“One of the first things I say to people who walk in and ask about being an extra is, ‘You have to be available,’” said a person at Karen Clifton Agency. Inc. “The next thing I say is, ‘You can’t make a living at this.’”

1. What kind of people are movie extras?

A. TV series makers.                                B. Casting directors.

C. Non-professional movie actors.          D. Agents for movie stars.

2. According to the passage, movie extras should    

A. have special talents                  B. have a flexible schedule

C. make good connections          D. make hundreds of phone calls daily

3. Why do white collar workers most probably like to be movie extras?

A. They want to make more money.

B. They want to start a career in acting.

C. They think their regular job is boring.

D. They think being on the stage is enjoyable.

4. The underlined word “turnover” in the sixth paragraph probably means    

A. business profit B. the loss of staff

C. market demand                         D. operation expenses
