单选题 {{B}}Passage Two{{/B}}

According to the United States government, people are classified as homeless if they have no place to
stay and no expectation of finding a place for the next thirty days. Although technically accurate, that is an impersonal assessment of an enormous and very human problem.
The homeless population represents all of us Americans. It includes men and women, the elderly, children, and infants. Its members are from all ethnic(种族的) groups. What they have in common is poverty.
Currently in the U. S. , thirty-nine million people live in poverty. When money is really tight, paying the rent or buying food often becomes a choice. Government assistance in the form of food stamps does help but, as one homeless man explains, you can't pay the rent with food stamps.
With no money for rent, the streets and homeless shelters become the alternative. Although men constitute the largest group within the homeless population, homeless women with children are rapidly joining them. In fact, one quarter of the homeless people in the U. S. are teenagers and young children.
People may become homeless for numerous reasons. However, there are certain factors that many of these individuals have in common. They include a lack of adequate education and job skills. A majority of the teenagers and adults have not completed high school.
The abuse of alcohol and drugs is also a common factor One third of the adult homeless population abuses alcohol, while one quarter of the same group uses drugs.
Some members of this population suffer mental health problems. Within the past several years many institutions for the mentally ill have been closed and their patients sent "home". Unfortunately, a number of those people have no home to go to and they are unable to adequately look after themselves.
Job loss in today's economy has also become a real factor in the loss of people's homes. The breakup of families through abandonment and divorce are also contributing factors, particularly when there are children involved. The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads.

【正确答案】 D

【答案解析】[解析] 从"there are certain factors that many of these individuals have in common．They include a lack of adequate education and job skills．(有很多原因造成这样的情况，包括投有足够的教育背景和工作技能。)可以判断A不正确。从“The abuse of alcohol and drugs is also a common factor．(滥用酒精和药物也是原因之一。)”可以判断B不正确。从“Some members of this population suffer mental health problems，Within the past several years many institutions for the mentally ill have been closed and their patients sent‘home’．Unforumately，a number of those people have no home to go(有些人是因为精神问题。随着近年来许多这类机构的关门，很多精神病人被遣送回家，但是实际上他们无家可归)，”可以判断 C不正确。

单选题 The breakup of families is likely to lead to homelessness because a parent with kids may ______.

【正确答案】 C

【答案解析】[解析] 参见文章最后一句话：The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads．被分到需要照顾孩子的父母一方如果没有足够的收入只有依靠收容站了。问题实际是把原文的最后一句换了一种说法，把forcelo换成 lead to，把inadequate income换成not have enough income。
