Traditional Ideas about MarriageAlmost every society has certain traditional ideas about
Traditional Ideas about Marriage

Almost every society has certain traditional ideas about marriage. For example,most societies expect men and women to marry. Most cultures also have traditions about the role and duties of a husband and a wife. Traditionally,the husband is expected to earn a living,and the wife is expected to keep house and raise children.

Many Americans did not follow traditional marriage patterns. For example,a large number of married couples share responsibilities that have been traditionally handled by either the husband or the wife. An increasing number of married women have paying jobs and help support their families financially. In 1940s,about 15 percent of all married women earned money. In the early 1990s,about 60 percent held a full-or part-time job. More and more husbands share responsibilities traditionally handled by women,such as cooking,doing housework,and caring for children.

On the average,men and women stay single longer than they once did. In 1950s,men married at an average age of 23,and women married at an average age of 20. By the mid-1990s,the average marriage age was about 26.5 for men and about 24.5 for women.

An increasing number of people choose not to marry. If a man and a woman wish to avoid marriage,they may decide to live together with no formal obligations to each other. This arrangement is more common among young adults,but some couples of all ages live together without marrying. (239 words)

How do young children learn to have good values? How can parents teach their children
How do young children learn to have good values? How can parents teach their children about the importance of kindness, patience, and self-discipline? At a time when more and more parents worry about the negative and violent images(暴力形象) their children see on TV, in the movies and, on the Internet, some are turning to fairy tales(童话) as a way to teach their young ones how to behave in society.

Fairy tales were not always intended for children.We know this because some of these stories have existed for hundreds of years and were passed down from generation to generation through songs and drama.They were considered entertainment for everyone, not only for young people.In these ancient stories, the heroes were extremely clever, fiercely independent, and never gave up.Over the years, some of the heroes’ qualities and story lines have been changed to fit the times. Psychologists think that fairy tales have a positive influence on children because they present the two sides of good and evil very clearly.When children hear the stories, they develop sympathetic feelings for the heroic characters.In each tale, they can see that there are many different kinds of people in the world and that we all have a choice about what kind of person we want to be.We can choose to do good actions, rather that bad ones, in our lives.

What kind of values can children learn from fairy tales? In “The Princess and the Pea,” a poorly dressed girl who insists she is a princess is given a difficult test by the Queen.When she passes the test, we learn that she is rewarded because she stayed true to herself.In “The Little Mermaid,” the mermaid(美人鱼)who lives under the sea longs to be with the humans on land.Through her experiences, we learn about the importance of living with and accepting other cultures.In “Pinocchio,” a wooden puppet(木偶)turns into a boy when he finally learns how to tell the truth. Teaching values is the reason most often given for teaching literature and encouraging reading.These old stories can indeed teach us lessons about human relationships that are universal(普遍的) enough to survive throughout the centuries.This might be the reason why they have been around for so long and are unlikely to disappear any time soon.

1.What do we learn about fairy tales from the passage? _______

It is a great truth because once we truly understand and accept it. Then life is no lo
nger difficult. Most people do not fully see this truth. Instead they complain about their problems and difficulties as if life should be easy. It seems to them that difficulties represent (代表) a special kind of suffering especially forced upon them or else upon their families, their class, or even their nation.

What makes life difficult is the process of facing and solving problems and it is a painful one. Problems, depending on their nature, cause us sadness or, loneliness or regret or anger of fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.Yet, it is in this whole process of solving problems that life has its meaning. Problems are the serious test that tells us success from failure. When we desire to encourage the growth of human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, "Those things that hurt, instruct." It is for this reason that wise people learn not to fear but to welcome the pain of problems.

Most personnel managers agree that job interviews are one of the least objective recru
itment methods.But the advantages of testing are not going to change the attraction of the interview to employers.The appeal of the interview has everything to do with the human factor.

Most people believe that they are a reasonable judge of character and trust their instinctive feelings.We might use some kind of test to aid the selection process, but we usually pick a candidate who interviews well, has good qualifications and an impressive work record.

But suppose the candidate lies or is less than completely honest.“This can be a serious problem for employers,” explains Alan Conrad, Chief Executive at Optimus Recruitment.“The most difficult liars to find are those who tell halftruths rather than complete lies.” Research shows that up to 75 percent of resumes are inaccurate on purpose.The most common practice is omission.

Interviewer should therefore concentrate on areas of uncertainty such as gaps between periods of employment and job descriptions that seem strange.“Focusing on these areas will force candidates to tell the truth or become increasingly dishonest.This is usually when people show their anxiety by their body language.Sweat on the upper lip, false smiles and nervous hand movements all indicate discomfort.”

Conrad does not suggest an aggressive policystyle. interview technique, but insists that close inspection of a resume is absolutely essential.Only by asking the right questions can you confirm the suitability of the candidate or put pressure on those who are being less than completely honest.

1.The best title of this passage can be ______.

A.Disadvantages of Job Interviews

B.Advantages of Job Interviews

C.How to Catch Out the Dishonest Candidate

D.How to Find a Job by Tricks

2.The liars hard to recognize are those who tell ______.

A.partial truths

B.mainly truths

C.complete truths

D.complete lies

3.How were the job applicants able to lie without being detected?

A.By using their body language

B.By telling some unbelievable lies

C.By leaving out some necessary information

D.By providing more information than needed

4.In order to pick up a qualified and an honest candidate, Conrad suggests that we ______.

A.correct the resumes intentionally

B.compare one’s resume with others

C.examine the resumes carefully

D.inspect the candidates aggressively

5.What is the author’s attitude towards job interviews?

Robert had just moved into the street and he felt strange that he was not wanted. He k
new that perhaps the other boys were trying to get an idea of what kind of a boy he was. This did not help him to make himself less lonely. He was new and he had to be tested. Still, proving himself would not be all that easy. He did not want to run with the boys or get into something against the law to prove that he was strong. No! He must show what he was made of in a more helpful way. That’s when he got the idea.

The next day was Saturday. He knew that most of the boys would be down on the playground and choose up sides for the Saturday game. Robert knew he could play well and that just might be enough to prove he was strong, and to make friends with them. He arrived early and did his step exercises. He shot the ball several times and did some other exercises—the most difficult and most wonderful in basketball. Then the boys came. Robert went through what he had done before the game and showed what he could do. No one said a word. The boys just looked at each other and thought about it. In the end, when it was all over, the biggest of the group just smiled and shook his head. Robert knew he had made it.

1. What does “This did not help to make him less lonely” mean?()

A、Robert felt more lonely because the other boys wanted to test him.

B、Robert did not want himself to be less lonely.

C、Robert felt as lonely as before when the other boys tried to find out what kind of a boy he was.

D、The other boys did not want to make Robert feel less lonely.

Peter, a high school student, was pretty busy with school, and he was on the soccer team
. High school was hard,because everyone wanted to have nice clothes, hang out,drive cars, and all these cost money. Peter’s father was the sort of guy that believed you had to earn whatever you got,so he wasn’t just about to hand over lots of money for Peter to use to have fun. So,he had to get a job.

During his freshman year summer vacation, his classmate got him a job working on a hay (干草) farm. He threw hay up into wagons as the tractor drove around fields, and then they stacked (剁起) it in the hot barn. It was a hot,low­paying job.

He once worked a few nights a week at a grocery store. He put things on the shelf. It was a lot of lifting and carrying,and his arms were strong from this and the previous job. It was dull and didn’t pay much.

He took some time off when soccer got serious,but the following summer he tried working at a lumber yard. It was hot outside, but he got a lot of exercise lifting and carrying things like boards and drywall. He also learned a lot about building supplies. It still didn’t pay well.

From there, he spent a year doing some tutoring for a friend of the family, but that was piecemeal. His first real job came the last year at school, when he fixed registers and worked on computers at a big box store. It was his favorite job yet, but it still didn’t pay well.

What Peter realized with all of these jobs was that he needed a better paying job! The only way to get that was to get trained or educated. He could go to school and get a 2­year degree in an office or technical position. His other choices were going to a 4­year college or joining the army. He wasn’t sure what he was going to do yet, but he knew he had to do something. Jobs were a lot of work, money was hard to earn,but he liked staying busy and being able to buy things. Peter wanted the most out of life, and that meant education.

25.All the jobs Peter had taken had one thing in common:_____.

A、They didn’t pay well

B、They were dull and tiresome

C、They needed hard labor

D、They were done during his vacation

26._____was the most important for Peter if he wanted a good job.

A、Confidence

B、Education

C、Opportunity

D、Wisdom

27.We can learn from the text that_____.

A、Peter knew what to do with his future

B、Peter’s father didn’t care about him

C、It was very hard for Peter to make his choices

D、Peter was determined to do whatever he liked
