Child maltreatment is a global problem with serious life long consequences.There are no reliable global estimates for the prevalence of child maltreatment. Data for many countries,especially low and middle income countries,are lacking.
Child maltreatment is complex and difficult to study. Current estimates vary widely depending on the country and the method of research used.Nonetheless,international studies reveal that approximately 20% of women and 5%一10% of men report being sexually abused as children.While 25%一50%of all children report being physically abused. Additionally,many children are subject to emotional abuse(sometimes referred to as psychological abuse).
Every year,there are an estimated 31 ,000 homicide（他杀）deaths in children under 15. This number underestimates the true extent of the problem,as a significant proportion of deaths due to child maltreatment are incorrectly attributed to（归因于）falls, burns and drowning.
Child maltreatment causes suffering to children and families and can have long-term consequences.Maltreatment causes stress that is associated with disruption in early brain development. Extreme stress can impair the development of the nervous and immune systems.Consequently,as adults,maltreated children are at increased risk for behavioural,physical and mental health problems.Via the behavioural and mental health consequences,maltreatment can contribute to heart disease,cancer,suicide and sexually transmitted infections.
Beyond the health consequences of child maltreatment,there is an economic impact,including :ost of hospitalization,mental health treatment,child welfare,and longer-term health cost.
A number of risk factor for child maltreatment has been identified.These risk factors are not present in all social and cultural contexts,but provide an overview when attempting to understand the causes of child maltreatment.
It is important to emphasize that children are the victims and are never to blame（责怪）for maltreatment.A number of characteristics of an individual child may increase the likelihood of being maltreated,such as being either under four years old or an adolescent,being unwanted,or failing to fulfill the expectations of parents and having special need,crying persistently or having abnormal physical features.

Many homicide deaths in children under 15 are wrongly categorized into the following types except_______according to the passage.
A:drowning in swimming
B:diarrhea

资料：Up to 80 per cent of the world’s middle classes will live in developing countries by 2030 thanks to surprising recent gains in poverty reduction, according to a United Nations report published on Thursday.
“Never in history have the living conditions and prospects of so many people changed so dramatically and so fast.” concludes the UN’s latest Development Report. “The world is witnessing an epochal ‘global rebalancing’.”
Underpinning the improvements in the human development index（HDI） was rapid growth in countries such as China, India and Brazil, with China and India having doubled per capita economic output in less than 20 years. But the study stressed that growth and improvements in HDI spread far beyond the four Bric countries of Brazil, Russia, India and China, and included at least 40 countries that had accompanied greater economic dynamism with effective poverty-reduction policies.
Afghanistan, Sierra Leone, Ethiopia, Rwanda and Angola were among 14 countries that have recorded gains in HDI of more than 2 per cent a year since 2000. Partly as a result, the report found that worldwide extreme income poverty has plunged from 43 per cent in 1990 to just 22 per cent in 2008, including more than 500m being lifted out of poverty in China alone. The report stated that such gains had already helped the world achieve the main poverty eradication goal of the so-called Millennium Development Goals, which called for the share of people living on less than $1.25 a day to be cut by half from 1990 to 2015.
Underpinning this poverty reduction was developing countries’ increasing share of global trade, which grew from 25 per cent to 47 per cent between 1980 and 2010. “The south as a whole is driving global economic growth and societal change for the first time in centuries,” says the report.
The report found that trade among developing countries was the biggest factor in that expansion, increasing from less than 10 per cent of total global trade to more than 30 per cent. “Trade between countries in the south will overtake that between developed nations,” the report said.

All of the following are factors for poverty reduction except ______.

A.greater economic dynamism
B.aid from developed countries
C.changes of developing countries
D.trade among developing countries

The______goal of the project is to expand the scientific knowledge relevant to improving health outcomes for women and children in low income countries.

A.entire
B.total
C.target
D.overall

Goal of American Education

Education is an enormous and expensive part of American life.Its size is matched by its variety.
Differences in American schools compared with those found in the majority of other countries lie in the
fact that education here has long been intended for everyone一not just for a privileged elite.Schools are ex-
pected to meet the needs of every child,regardless of ability,and also the needs of society itself. This means
that public schools offer more than academic subjects.It surprises many people when they come here to find
high schools offering such courses as typing,sewing,radio repair,computer programming or driver training,
along with traditional academic subjects such as mathematics,history,and languages.Students choose their
curricula depending on their interests,future goals,and level of ability. The underlying goal of American edu-
cation is to develop every child to the utmost of his or her own possibilities,and to give each one a sense of
civic and community consciousness.
Schools have traditionally played an important role in creating national unity and"Americanizing"the
millions of immigrants who have poured into this country from many different backgrounds and origins.
Schools still play a large role in the community,especially in the small towns.
The approach to teaching may seem unfamiliar to many,not only because it is informal,but also
because there is not much emphasis on learning facts.Instead,Americans try to teach their children to think
for themselves and to develop their own intellectual and creative abilities.Students spend much time,learning
how to use resource materials,libraries,statistics and computers.Americans believe that if children are
taught to reason well and to research well,they will be able to find whatever facts they need throughout the
rest of their lives.Knowing how to solve problems is considered more important than the accumulation of
facts.
This is America's answer to the searching question that thoughtful parents all over the world are asking
themselves in the fast-moving time:"How can one prepare today's child for a tomorrow that one can neither
predict nor understand?"

Which of the following best states the feature of American education that makes it different from education in other countries?
A:The large number of its schools.
B:The variety of the courses offered in its schools.
C:Its special consideration given to immigrants.
D:Its underlying goal to develop every child's abilities to the fullest extent.

Preventing Child Maltreatment

Child maltreatment is a global problem with serious life-long consequences.There are no reliable global
estimates for the prevalence of child maltreatment.Data for many countries,especially low and middle income
countries,are lacking.
Child maltreatment is complex and difficult to study.Current estimates vary widely depending on the
country and the method of research used.Nonetheless,international studies reveal that approximately 20% of
women and 5-10% of men report being sexually abused as children,while 25-50% of all children report
being physically abused.Additionally,many children are subject to emotional abuse(sometimes referred to as
psychological abuse).
Every year,there are an estimated 31 ,000 homicide deaths in children under 15.This number underestimates
the true extent of the problem,as a significant proportion of deaths due to child maltreatment are incorrectly
attributed to falls,bums and drowning.
Child maltreatment causes suffering to children and families and can have long-term consequences.
Maltreatment causes stress that is associated with disruption in early brain development. Extreme stress can
impair the development of the nervous and immune systems.Consequently,as adults,maltreated children are at
increased risk for behavioural,physical and mental health problems.Via the behavioural and mental health
consequences,maltreatment can contribute to heart disease,cancer,suicide,and sexually transmitted infections.
Beyond the health consequences of child maltreatment,there is an economic impact,including costs of
hospitalization,mental health treatment,child welfare,and longer-term health costs.
A number of risk factors for child maltreatment have been identified.These risk factors are not present
in all social and cultural contexts,but provide an overview when attempting to understand the causes of child
maltreatment.
It is important to emphasize that children are the victims and are never to blame for maltreatment. A
number of characteristics of an individual child may increase the likelihood of being maltreated,such as being
either under four years old or an adolescent,being unwanted,or failing to fulfill the expectations of parents
and having special needs,crying persistently or having abnormal physical features.

Child maltreatment can bring all the following consequences EXCEPT__________.
A:stress
B:suicide
C:heart disease
D:poor memory

Global Cancer Rates to Rise by 50% by 2020

The number of new cancer cases worldwide is expected to increase by 50%by the year
2020.But a new report suggests that as many as a third of new cancers could be avoided
by adopting healthier lifestyles and through public health action.
The World Cancer Report,released by the International Agency for Research on
Cancer,shows that cancer has now emerged as a major public health threat in developing
countries as well as rich ones.
Overall,cancer was responsible for 12%of all deaths in 2000.But in many countries
more than a quarter of all deaths are caused by cancer.
The report shows that 1 0 million new cancers were diagnosed globally in 2000,and that
number is expected to rise to 15 million by 2020.Researchers say most of that increase will
mainly be due to steadily aging populations in both developed and developing countries and
current trends in smoking and other unhealthy habits.
"Cancer has emerged as a major public health problem in developing countries for the
first time, matching its effect in industrialized（工业化的）countries , " said researcher Paul
Kleihues,MD,director of IARC,in a news release."Once considered a'Western'
disease,the Report highlights that more than 50 percent of the world's cancer burden,in
terms of both numbers of cases and deaths,already occurs in developing countries."
The risk of being diagnosed with cancer in developed countries is double that in less-
developed ones.However,the risk of dying from cancer is much higher in developing
countries , where 80% of cancer patients already have late-stage incurable tumors（肿瘤）
at the time of diagnosis.
Researchers say cancer rates have traditionally been higher in developed countries due
to greater exposure to tobacco,occupational carcinogens（致癌物）,and an unhealthy
Western diet and lifestyle.As less-developed countries become industrialized and more
prosperous,they tend to adopt the high-fat diet and low physical activity levels typically seen
in the West,which increase cancer rates.

Which of the following statements is NOT correct?
A:There were 1 0 million cancer patients worldwide in 2000.
B:Generally,cancer accounted for 12% of all deaths in 2000.
C:Cancer is the cause of over 25%of all deaths in many countries.
D:It is expected that global cancer rates will go up by 50%by 2020.
