Understanding Autism

1 Autism（孤独症）is a life-long developmental disability that prevents individuals from
properly understanding what they see,hear and other senses.This results in severe
problems of social relationships,communication and behavior. Individuals with autism have
to painstakingly（费力地）learn normal patterns of speech and communication, and
appropriate ways to relate to people,objects and events,in a similar manner to those who
have had a stroke.
2 The cause of autism is still unknown.Some research suggests a physical problem
affecting those parts of the brain that process language and information coming in from the
senses. There may be some imbalance of certain chemicals in the brain. Genetic（遗传的）
factors may sometimes be involved.Autism may indeed result from a combination of several
"causes".
3 Most people with mental retardation（智力迟钝）show relatively even skill development.
Individuals with autism,however,typically show uneven skill development,with deficits（欠
缺）in certain areas一most frequently in their ability to communicate and relate to others一
and distinct skills in other areas.It is important to distinguish autism from mental retardation
or other disorders , since diagnostic（诊断的）confusion may lead to inappropriate and
ineffective treatment techniques.
4 In general,individuals with autism perlorm best at jobs which are structured and involve
a degree of repetition.Some people who have autism are working as artists,piano tuners,
painters,farm workers,office workers,computer operators,dishwashers,assembly line
workers,or employees of sheltered workshops or other sheltered work settings.

A typical feature of people with autism is their uneven_______.
A:different techniques
B:social relationships and communication
C:language and information
D:several causes working together
E:a degree of repetition
F:skill development

Human and the Earth

In terms of the evolution of life on Earth,human beings have just arrived.Despite their shori time on Earth,however,people have brought about enormous changes to the surface of the planet一changes far out of proportion to the interval of time they have occupied it.
People have more control over their surroundings than any other species on Earth.With the combination of intelligence and manual skill(allowing us to make and use tools),people have found ways to use plant and animal resources,mineral ores,fuels,and many other materials and resources from the Earth.
As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.
As the human population grows,people consume more.Clearly,some locations on Earth already have too many people;in many of these areas,future increases will surely bring about more poverty and suffering. Yet people in rich nations use proportionally far more of the available resources than people in poorer nations.As they consume these resources without restraint,they also waste large amounts of them.
People are only a very small fraction of all the living things on the planet.Yet their numbers create a drain on resources that can't be renewed.For example,the amount of water on Earth is limited,this water is cleaned through natural processes.However,the natural processes for filtering water can clean only a certain amount of water by removing the pollution.Likewise,a limited amount of petroleum can be found under the Earth's surface.Petroleum is a valuable resource.Should people use it up to manufacture petrol for automobiles?As people work to control the planet and make life comfortable,are they using up resources that are needed for their survival?

Why have people more control over their surroundings than any other species on Earth?
A:Because of their intelligence and manual skill.
B:Because they can use plant and animal resources,mineral ores and fuels.
C:Because they are cleverer than any other animals on Earth.
D:Both A and B.

Prolonging Human Life

1.Prolonging human life has increased the size of the human population.Many people alive today would have died of childhood diseases if they had been born 100 years ago.Because more people live longer,there are more people around at any given time.In fact,it is a decrease in death rates,not an increase in birthrates,that has led to the population explosion.
2.Prolonging human life has also increased the dependency load.In all societies,people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures,old people who could not keep up might be left behind to die.In times of famine,infants might be allowed to die because they could not survive if their parents starved,whereas if the parents survived they could have another child.
3.In most contemporary societies,people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work.We also have rules which require people to retire at a certain age.Unless these people were able to save money for their retirement,somebody else must support them.In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people.Unless they have wealth or private or government insurance,they must often"go on welfare"if they have a serious illness.
4.When older people become senile or too weak and ill to care for themselves,they create grave problems for their families.In the past and in some traditional cultures,they would be cared for at home until they died.Today,with most members of a household working or in school,there is often no one at home who can care for a sick or weak person.To meet this need,a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups.While a few of these institutions are good,most of them are simply"dumping grounds"for the dying in which"care"is given by poorly paid,overworked,and under-skilled personnel.

Paragraph 4________
A:The old people are heavy load for the society.
B:Prolonging human life may lead to population explosion.
C:How to prolong human life.
D:Dependency load caused by prolonging human life.
E:Increased birthrate helps prolong human life.
F: How the old people are cared for when they are getting weak in contemporary society.

根据下列内容，回答196-200题。
If the population of the earth goes on increasing at its present rate, there will eventually notbe enough resources left to sustain life on the planet. By the middle of the 21st century, if presenttrends continue, we will have used up all the oil that drives our cars, for example. Even if scien-tists develop new ways of feeding the human race, the crowded conditions on earth will make itnecessary for us to look for open space somewhere else. But none of the other planets in our solarsystem are capable of supporting life at present. One possible solution to the problem, however,
has recently been suggested by an American scientist, Professor Carl Sagan.
Sagan believes that before the earth's resources are completely exhausted it will be possible tochange the atmosphere of Venus and so create a new world almost as large as earth itself. The dif-ficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.
Sagan proposes that algae organisms, which can live in extremely hot or cold atmospheres andat the same time produce oxygen, should be bred in conditions similar to those on Venus. As soonas this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venusand fire the rockets into the atmosphere. In a fairly short time, the algae will break down the car-bon dioxide into oxygen and carbon.
When the algae have done their work, the atmosphere will become cooler, but before mancan set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planetwill still be too hot for men to land on it but the rain will eventually fall and in a few years some-thing like earth will be reproduced on Venus.
In the long run, the most difficult problem caused by population growth on earth willprobably be the lack of __________.

A.food
B.oil
C.space
D.resources
