People in the western state of California who are in the United States illegally can now request a driver's license. The law went into effect on January l. California is not the first American state with such a law, but it has the largest number of illegal immigrants. More than a million people began to request licenses shortly after the new state law went into effect. Among them was Christian Alvarado. Mr. Alvarado entered the United States from El Salvador eight years ago without permission from the U.S. government. Some call such people "illegal immigrants." Others call them "undocumented immigrants".

Mr. Alvarado thinks it so exciting, for he has been waiting for the license for a long time. But some are worried that their personal information will be used to find them and deport them. Armando Botello is a spokesman for the California Department of Motor Vehicles, or DMV. He says people should not be afraid, for such information will not be shared.

The new licenses are the same as licenses given to citizens except that they have the words "Federal Limits Apply". That means the license cannot be used to travel on an airplane or enter a federal building. Ana Garcia, working at the Central American Resource Center, says some illegal immigrants fear those words will be used to abuse them. Civil rights groups say the police and others will not.

Dan Schnur, a political scientist at the University of Southern California, said that the main argument against the new law is that it rewards illegal behavior. But Professor Schnur argued that young, white Americans generally support immigration reform, including giving driver's licenses to illegal immigrants

"It's simply because they grew up in a much more multicultural society than their parents or their grandparents did." Professor Schnur says he believes the changes in beliefs about illegal immigrants that have taken place in California will spread throughout the United States.

1.Why did the new law make Mr. Alvarado excited?

A. Because he can request a driver's license.

B. Because he became a legal immigrant of California.

C. Because he got his driving license as an illegal immigrant.

D. Because a law went into effect for the new immigrants.

2.What is the difference of the new licenses compared to those given to citizens'?

A. The words “Federal Limits Apply” will abuse illegal immigrants

B. They can't be used to travel on an airplane or enter a federal building.

C. They can be used to act against the police and other people.

D. With the words "Federal Limits Apply", immigrants can enjoy special rights.

3.What’s the public's attitude towards the new law released on January l in California?

A. supportive B. negative

C. neutral D. controversial

However wealthy we may be, we can never find enough hours in the day to do everything we want. Economics deals with this problem through the concept of opportunity cost, which simply refers to whether someone’s time or money could be better spent on something else.

Every hour of our time has a value. For every hour we work at one job we could quite easily be doing another, or be sleeping or watching a film. Each of these options has a different opportunity cost—namely, what they cost us in missed opportunities.

Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium. Why not, you might reason, watch the game from home and use the leftover money and time to have dinner with friends? This—the alternative use of your cash and time—is the opportunity cost.

For economists, every decision is made by knowledge of what one must forgo—in terms of money and enjoyment—in order to take it up. By knowing precisely what you are receiving and what you are missing out on, you ought to be able to make better-informed, more reasonable decisions. Consider that most famous economic rule of all: there’s no such thing as a free lunch. Even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities.

Some people find the idea of opportunity cost extremely discouraging: imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable. Yet, in a sense it’s human nature to do precisely that we assess the advantages and disadvantages of decisions all the time.

In the business world, a popular phrase is “value for money.” People want their cash to go as far as possible. However, another is fast obtaining an advantage: “value for time.” The biggest restriction on our resources is the number of hours we can devote to something, so we look to maximize the return we get on our investment of time. By reading this passage you are giving over a bit of your time which could be spent doing other activities, such as sleeping and eating. In return, however, this passage will help you to think like an economist, closely considering the opportunity cost of each of your decisions.

1.According to the passage, the concept of “opportunity cost” is applied to ________.

A. weighing the choice of opportunities

B. reducing missed opportunities

C. making more money

D. taking more opportunities

2.The “leftover ... time” in Paragraph 3 probably refers to the time ________.

A. taken to have dinner with friends

B. spared for watching the match at home

C. saved from not going to watch the match

D. spent on the way to and from the match

3.What are forgone opportunities?

A. Opportunities you make up for.

B. Opportunities you forget in decision-making.

C. Opportunities you give up for better ones.

D. Opportunities you miss accidentally.

4.What is the author’s attitude towards the concept of “opportunity cost”?

A. Indifferent B. Negative

C. Subjective D. Objective

Teamwork is all about working together to achieve a common goal or purpose. Is teamwork out of date? Why is it so hard to effectively conduct teamwork in those things?

One way we employ teamwork in everyday lives is by becoming a parent. It is a parent's job to teach their children and the basic skills and give them the knowledge they need to be successful in life. For example, the mother teaches her children manners and good health skills, while the father teaches them how to catch a ball or drive a car. However, in today's society, we find that more and more parents are experiencing that the teamwork is a one-sided thing. According to a report, there are 13.7 million single parents raising their children in the US and this could be due to the fact that parents don't take responsibility for their children, so they leave one parent to do it alone. This is a sad fact, but it reflects that effective teamwork is losing ground in the parenting aspect of our everyday lives.

Another place where teamwork affects us greatly is in our jobs. It doesn't matter if you are a small or large company; if you have at least one employee and yourself, then teamwork will be present. I have noticed that with the current economic recession（衰退期）, people are racing to grab jobs but the quality of people's work has gone down greatly. It just appears to me that people do not take pride in their work any more. They want to get to work as fast as they can, just to receive the paycheck, but their quality standards fly right out the window. So I think teamwork is losing its ground in the workforce. There are too many people who want to work independently and forget they are a part of a team.

As you can see, we run into the aspects of teamwork in just about everything we do. Do you believe teamwork is really losing ground in today's society? I think it is.

1.Why does teamwork disappear in the parenting aspect of our daily life?

A. Parents have no time to spare with their children.

B. Parents have no chances to teach their children about it.

C. Many children are often brought up by a single parent.

D. Many children are independent to deal with their matters.

2.Teamwork is losing ground in workforce mainly because -

A. workers don't like to work together with others

B. workers' sense is affected by economic recession

C. workers want to prove they are more capable

D. fewer workers are employed to save money

3.The author wants us to believe his opinion by_ _．

A. listing some data

B. giving some examples

C. asking some questions

D. analyzing some cases

4.The underlined phrase "fly right out the window" in Paragraph 3 means_______ .

A. disappear B. improve

C. increase D. matter
