More than half of rich Americans have not shown their full wealth to their children，a new survey showed last Tuesday.

The survey，published by the Bank of America，studied the rich with $3 million or more in assets.It found that “surprisingly few of those surveyed have welldeveloped plans to preserve and pass on their assets to their children”．

The majority of the 457 people surveyed are selfmade，firstgeneration rich.Fiftytwo percent of parents have chosen not to tell their children just how wealthy they are，and 15 percent have given away nothing about the family wealth.One in three parents said they had never thought to do it.

They are worried that their children would become lazy，spend money freely，make bad decisions and even become a target for gold diggers.

Only 34 percent strongly agreed that their children would be able to handle any inheritance (遗产) they plan to leave them.

“There is an expectation about the wealthy parents that they have a responsibility to pass down their fortune to the next generation，” said Sallie Krawcheck，president of the Global Wealth and Investment Management of the Bank of America.“Our research，however，uncovered changing views of what one generation owes the next.”

The trend is led by the world’s richest man Bill Gates，who promised in 2008 that he would leave his $58 billion fortune to the charity started by him and his wife，the Bill and Malinda Gates Foundation (基金会)，and not to his children.

“We want to give it back to society in the way that it will have the most positive impact，” he said.

Of his plans for his children，Gates said：“I will give the kids some money but not a meaningful percentage...they will need to work but they will feel reasonably taken care of.”

【1】We can learn from the passage that________.

A．rich parents may not know how to manage their inheritance

B．rich parents don’t equal rich kids，at least in the US

C．American children don’t get to inherit their parents’ wealth

D．poor children don’t expect themselves to be as rich as their parents

【2】According to the survey，most rich Americans________.

A．think they owe their children nothing

B．think it best to give their money back to society

C．doubt their children’s ability to handle wealth

D．are confident of their children’s ability to handle wealth

【3】The underlined word “they” in Paragraph 6 refers to________.

A．responsible children B．Bill Gates and his wife

C．firstgeneration rich D．rich parents

【4】From the last paragraph，we can see that Bill Gates wants to show________.

A．the trend of leaving no inheritance to children

B．the positive impact of charity on society

C．the way of giving back to society

D．the importance of independence for children

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

It is a great truth that once we truly understand and accept it, life is no longer difficult. Most people do not fully see this truth. 1 It seems to them that their difficulties represent a special kind of suffering especially forced upon them or their families, their class, or even their nation.

2 Problems, depending on their nature, cause us sadness or loneliness or regret or anger or 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.

4 When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. 5 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.

A. Problems are the serious test that tells success from failure.

B. Life is not a trap set for us by God so that he can condemn us for failing.

C. It is through the pain of meeting and working out problems that we learn.

D. Yet, it is in this whole process of solving problems that we understand the meaning of life.

E. Instead they complain about their problems and difficulties as if we understand the meaning of life.

F. We can participate in problem-solving collaboration(合作) groups.

G. What makes life difficult is that the process of facing and solving problems is a painful one.

【题目】B

My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t get any channels showing all-night movies or I would never have gotten to bed.

Then I started developing a problem with the set that involved static(静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.

When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether. My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.

A. He got an older model than he had expected.

B. He couldn’t return it when it was broken.

【2】Which of the following can best replace the phrase ＂signed off＂ in Paragraph 1?

A. ended all their programs B. provided fewer channels

C. changed to commercials D. showed all-night movies

【3】How did the author finally get his TV set working again?

A. By shaking and hitting it. B. By turning it on and off.

C. By switching channels. D. By having it repaired.
