    【题目】日本、比利时、荷兰等国家的土地、矿产资源严重不足，而且人口密度很高，从人口合理容量来看，下列说法不正确的是

    A．一个国家或地区的现实人口是自然、社会、经济、历史共同作用的结果

    B．这些国家现存的人口数量就是人口合理容量

    C．地域的开放可以使得人口合理容量变大

    D．科学技术、生产力水平的提高有助于提高人口合理容量

    【答案】B

    【解析】

    试题分析：通过定义可知人口容量就是指在一定的自然资源和社会经济条件下一个国家或者地区所能容纳的最高人口数量。人口合理容量指有效和持续地利用资源。环境并获得最大的经济效益的情况下，一定地区所能容纳的人口数量。人口合理容量是一个理论指标。故B错误。地区开放程度能够较强区域间各种要素交流所以能够使得人口容量变大。故C项正确。科学技术、生产力水平的提高同样可以提高人口合理容量。故D 项正确。

    【题目】D

    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
