Can Buildings Be Designed to Resist Terrorist Attack?
In the aftermath of the terrorist attack on the World Trade Center,structural engineers are trying hard to
solve a question that a month ago would have been completely unthinkable:Can buildings be designed to
withstand catastrophic blasts inflicted by terrorists?
Ten days after the terrorist attacks on the twin towers,structural engineers from the University at Buffalo
and the Multidisciplinary Center for Earthquake Engineering Research(MCEER)headquartered at UB
traveled to ground zero as part of a project funded by the National Science Foundation.Visiting the site as
part of an MCEER reconnaissance visit,they spent two days beginning the task of formulating ideas about
how to design such structures arid to search for clues on how to do so in buildings that were damaged but still
are standing.
"Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade
Center,those buildings that are still standing,but that sustained damage,"said M.Bruneau,Ph.D."Our im-
mediate hope is that we can develop a better understanding as to why those buildings remain standing,while
our long-term goal is to see whether earthquake engineering technologies can be married to existing technolo-
gies to achieve enhanced performance of buildings in the event of terrorist attacks,"he added.
Photographs taken by the investigators demonstrate in startling detail the monumental damage inflicteed
on the World Trade Center towers and buildings in the vicinity.One building a block away from the towers
remains standing,but was badly damaged."This building is many meters away from the World Trade Center
and yet we see a column there that used to be part of that building,"explained A.Whittaker,Ph.D."The
column became a missile that shot across the road,through the window arid through the floor."
The visit to the area also revealed some surprises,according to the engineers.For example,the floor
framing system in one of the adjacent buildings was quite rugged,allowing floors that were pierced by tons of
falling debris to remain intact. " Highly redundant ductile（有延展性的）framing systems may provide a sim-
pie,but robust strategy for blast resistance,"he added.Other strategies may include providing alternate paths
for gravity loads in the event that a load一bearing column fails."We also need a better understanding of the
mechanism of collapse,"said A.Whittaker."We need to find out what causes a building to collapse and how
you can predict it."
A.Reinhorn,Ph.D.noted that"Earthquake shaking has led to the collapse of many buildings in the
past.It induces dynamic response and extremely high stresses and deformations in structural components.So-
lutions developed for earthquake-resistant design may be directly applicable to blast engineering and
terrorist-resistant design.Part of our mission now at UB is to transfer these solutions and to develop new ones
where none exist at present."
A surprising discovery made by the investigators during their visit to ground zero is that________.
A:floors in the adjacent building remain undamaged
B:some floor framing systems demonstrate resistance to explosion
C:simple floor framing systems are more blast resistant
D:floors in one of the adjacent buildings were pierced by tons of debris

Chimpanzees
1 Chimpanzees（黑猩猩）will soon be extinct（灭绝）.If the present rate of hunting and habitat（栖息地）destruction continues, then within 20 years, there will be no chimpanzees living in the wild. But this is more than an environmental or moral tragedy（悲剧）.Chimpan-zee extinction may also have profound implications（含意）for the survival of their distant relatives一human beings.
2 In 1975 the biologist Marie-Claire King and Allan Wilson discovered that the human and chimpanzee genomes（基因组）match by over 98%. Compare this to the mouse, used as model for human disease in lab tests,which shares only 60% of its DNA with us.In fact, chimpanzees are far more similar to humans than they are to any other species of monkey. As well as resembling us genetically,chimps are highly intelligent and able to use tools.These facts alone should be enough to make protection of chimps an urgent priority（优先）.But there is another,more selfish reason to preserve the chimp.
3 The chimpanzees' trump card（王牌）comes in the field of medical research. Chimpan-zees are so similar to humans that veterinarians（兽医）often refer to human medical text-books when treating them. Yet chimpanzees do show differences in several key areas.In parti-cular,chimps are much more resistant to a number of major diseases.It is this ability that is so interesting.
4 For example,chimps seem to show a much higher resistance than humans to HIV,the virus that causes AIDS. Indeed,their use as experimental animals in AIDS research has de-clined because they are so resistant.
5 By sequencing the chimp genome and pinpointing（找到）the place where the chimpan-zee DNA sequence differs from that of humans,scientists hope to be able to discover which part of the genetic code gives chimps their increased resistance to some diseases. This,they hope,will allow them to develop new and more effective treatments for the human forms of these diseases. Such treatments could include the production of new drugs or even the altera-tion（改变）of the human genetic sequence. The recently completed human genome sequen-cing project has shown that such an effort is now well within our reach.

More Than 8 Hours Sleep Too Much of a Good Thing
1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling re-freshed after a night's sleep than 8-hour sleepers.
3 These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine,demonstrate that people who want to get a good night's rest may not need to set aside more than 8 hours a night.He added that“it might be a good idea” for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cau-tioned that more research is needed to confirm this.
4 Previous studies have shown the potential dangers of chronic shortages of sleep一for instance,one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
5 For the current report,Kripke reviewed the responses of 1,004 adults to sleep ques-tionaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.
6 Kripke found that people who slept between 9 and 10 hours each night were more like-ly to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake.”he said.

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.
The maltreated children often bear all the following characteristics except________according to the passage.
A:they frequently and easily cry
B:they are in infant's or in adolescent period
C:they are often neglected by their parents or friends
D:they often try their best to meet the requirements from their parents
