As I was reading a recent story in Slate on 20-somethings complaining about how the economy was ruining their life plans, I couldn’t help but think the 20-somethings sounded like a bunch of spoiled children who grew up expecting everything to be easy for them. As a 20-something myself, I certainly share their disappointment: my husband and I probably won’t be able to buy a house until we’re in our 40s, and we too are burdened by student loans(贷款). But why should it be any different? Being young persons in America, shouldn’t they take up all of the challenges and opportunities that this country offers?

Consider some of these views shared in the Slate story: Jennifer, 29, owner of a two-bedroom apartment with her husband, worries that she won’t be able to have children for at least a decade because they can’t afford to buy a house yet.

I read that, and I thought, what planet is she living on where you need to own a house in order to have kids? Has she ever visited a developing country, or even downtown areas in this one? Home ownership is a luxury(奢华), not a fertility requirement.

A 26-year-old in the story despairs(绝望) that he can’t afford to get a Ph.D. in literature. Well, that sounds a bit like expressing disappointment that no one will pay you to write poetry on the beach in Thailand for five years.

Yes, it’s sad that these young people feel so lost. But I think the problem is their extremely high expectations, not economic reality. Beth Kobliner, author of Get a Financial Life: Personal Finance in Your Twenties and Thirties, says that she thinks people’s expectations are slowly adjusting, but today’s 20-somethings grew up at a time when everyone’s wealth appeared to be expanding. Their parents probably saw their home values rise along with their investments. “So you have people who have grown up in an environment where people had great expectations of what living well means,” says Kobliner.

This recession(衰退) will certainly play a role in forcing those expectations into more realistic group. In the meantime, it seems a lot better for our mental health to focus on being grateful－for our one-bedroom apartments, for living in modern cities, or perhaps just for being able to eat three meals a day－than on longing for some kind of luxury life.

67．What makes the author think the 20-somethings sound like a bunch of spoiled children?

       A．They expect everything to be easy for them.

       B．They complain that the economy is spoiling their life plans.

       C．They are reluctant to face all of the challenges.

       D．They are burdened by student loans.

68．The underlined word “fertility” in Paragraph 3 probably means        .

       A．baby production         B．pleasant       

       C．baby comfort                     D．essential

69．Which of the following is not one of the complaints of the 20-somethings?

       A．They can’t have children for at least a decade to buy a house.

       B．They have only one-bedroom apartment to live in.

       C．They can’t buy a house until 40 because of student loans.

       D．They despair at not being able to afford a Ph.D. in literature.

70．What is the author’s purpose of writing this passage?

       A．To tell us what the author’s attitude towards the 20 – somethings.

       B．To explain why young people can’t afford to buy a house.

       C．To suggest what we should do when young people’s high hopes create despair.

       D．To explain what the 20 – something’s high expectations are.

As is known to all, the organization and management of wages and salaries are very complex.
Generally speaking, the Accounts Department is responsible for calculations of pay, while the Personnel Department(人事部) is interested in discussions with the employees about pay.
If a firm wants to adopt a new wage and salary structure, it is essential that the firm should decide on a method of job evaluation(估价) and ways of measuring the performance of its employees. In order to be successful, that new pay structure will need agreement between Trade Unions and employers.
In job evaluation, all the requirements of each job are defined in a detailed job description. Each of those requirements is given a value, usually in “points”, which are added together to give a total value for the job. For middle and higher management, a special method is used to evaluate managers on their knowledge of the job, their responsibility, and their ability to solve problems.
Because of the difficulty in measuring management work, however, job grades for managers are often decided without reference to an evaluation system based on points.
In attempting to design a pay system, the Personnel Department should compare the value of each job with those in the job market. It should also consider economic factors such as the cost of living and the labor supply.
It is necessary that payment for a job should vary with any differences in the way that the job is performed. Where it is simply to measure the work done, as in the work done with the hands, monetary encouragement schemes are often chosen; for indirect workers, where measurement is difficult, methods of additional payments are employed.

For many parents , raising a teenager is like fighting a long war ,but years go by without any clear winner . Like a border conflict between neighboring countries ,the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace ,but neither feels it has any power to stop the conflict . In part ,this is because neither is willing to admit .any responsibility for starting it . From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course .the  teens see it in exactly the same way , except oppositely . Both feel trapped

In this article. I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over         unimportant things . Examples include the color of the teen’s hair, the cleanliness of the bedroom ,the preferred style of clothing , the child’s failure to eat a good breakfast before school ,or his tendency to sleep until noon on the weekends .Second ,blaming , the goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong . Third , needing to be right ,It doesn’t matter what the topic is –politics. The taws of physics ,or the proper way to break an egg –the point of these arguments is to prove that you are right and the other person is wrong .for both wish to be considered an authority --- someone who actually knows something --- and  therefore to command respect. Unfortunately , as long as long as parents and teens continue to assume that they know more than the other ,they’ll continue to fight these battles forever and never make any real progress

B. Both are about where to draw the line

C. Neither has any clear winner

D. Neither can be put to an end

56. What does the underlined part in Paragraph 2 mean?

A. The teens blame their parents for starting the conflict.

B. The teens agree with their parents on the cause of the conflict

C. The  teens accuse their parents of misleading them

D. The teens tend to have a full understanding of their parents

57.Parents and teens want to be right because they want to ________.

A. give orders to the other

B. know more than the other

C. gain respect from the other

D .get the other to behave properly

58. What will the author most probably discuss in the paragraph that follows?
