[填空题]The world health watchdogs are looking in the wrong places for the next dangerous epidemics, according to an analysis of global trends in emerging disease outbreaks over the past few decades.
The study gives a fresh perspective on global disease by tracking the history, from 1940 to 2004, of the emergence and spread of 335 infectious diseases. The extensive work helps to quantify the effect of well-known risk factors, such as population density, on the probability of a disease taking hold in a given area.
Although the data haven’t yet been used to map out specific future hotspots for disease, they do suggest that watchdog groups should invest more in monitoring regions such as tropical Africa, Latin America and Asia. These areas have the greatest threats of newly emerging epidemics, say the survey’s authors, but they have traditionally received the least surveillance.
A globally coordinated strategy is required to spot and stop outbreaks before they can spread acro

[不定项选择题]共用题干
Intelligence:a Changed View 1. Intelligence was believed to be a fixed entity,some faculty of the mind that we all possess and which determines in some way the extent of our achievements.Its value therefore,was as a predic-tor of children's future learning. If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently and the need for different types of school and even different ability groups within school was obvious.Intelligence tests could be used for streaming children according to ability at an early age;and at 11 these tests were superior to measures of attainment for selecting children for different types of secondary education. 2. Today,we are beginning to think differently. In the last few years,research has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence it-self. There is considerable evidence now which shows the great influence of environment both on a-chievement and intelligence.Children with poor home backgrounds not only do less well in their school work and intelligence tests but their performance tends to deteriorate gradually compared with that of their more fortunate classmates. 3 .There are evidences that support the view that we have to distinguish between genetic intelli- gence and observed intelligence.Any deficiency in the appropriate genes will restrict development no matter how stimulating the environment. We cannot observe and measure innate intelligence, whereas we can measure the effects of the interaction of whatever is inherited with whatever stimu-lation has been received from the environment. Researches have been investigation what happens in this interaction. 4. Two major findings have emerged from these researches.Firstly,the greater part of the devel-opment of observed intelligence occurs in the earliest years of life.It is estimated that 50 per cent of measurable intelligence at age 17 is already predictable by the age of four. Secondly,the most important factors in the environment are language and psychological aspects of the parent-child re- lationship.Much of the difference in measured intelligence between“privileged”and“disadvan- taged”children may be due to the latter's lack of appropriate verbal stimulation and the poverty of their perceptual experiences. 5. These research findings have led to a revision in our understanding of the nature of intelli- gence.Instead of it being some largely inherited fixed power of the mind,we now see it as a set of developed skills which a person copes with any environment. These skills have to be learned and, indeed,one of them is learning how to learn. 6 .The modern ideas concerning the nature of intelligence are bound to have some effect on our school system.In one respect a change is already occurring.With the move toward comprehensive education and the development of unstreamed classes,fewer children will be given the label “low IQ”which must inevitably condemn a child in his own,if not society's eyes.The idea that we can teach children to be intelligent in the same way that we can teach them reading or arithmetic is ac-cepted by more and more people.
It was once believed_______,and thus we can tell how successful he/she will be in the fu-ture according to his/her intelligence.
A.born to be more intelligent or less intelligent
B.have a better chance to develop his intelligence
C.taught to be more intelligent
D.that intelligence was something a baby was born with
E.and because of the lack of communication with his classmates
F.and partly has to do with a child's living environment
