Valuing water

Human beings use a little less than half the water available worldwide. Yet shortages and droughts(干旱) are causing starvation and poverty in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 51 years, many experts think we are on the edge of a widespread water crisis.

But that doesn’t have to be the result. Water shortages do not have to trouble the world—if we start valuing water more than we have in the past. Just as we began to value petrol more after the 1970s oil crisis, today we must start looking at water from a fresh economic view. We can no longer afford to consider water a nearly free resource of which we can use as much as we like in any way we want.

Instead, for all uses except the demand of the poor, governments should price water to reflect its real value. This means charging a fee for the water itself as well as for the supply costs.

Governments should also protect this source by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation(灌溉) water in the dry places is through small-scale projects, such as gathering rainfall in depressions(凹地) and pumping it to nearby cropland.

No matter what steps governments take to provide water more efficiently, they must change their ways to use water. Rather than control hundreds or even thousands of local, regional agencies that watch water use, countries should set up central authorities to manage water policy.

65. What is the real cause of the potential water crisis?

A. Only half of the world’s water can be used.

B. The world population is increasing faster and faster.

C. Half of the world’s resources have been seriously polluted.

D. Human beings have not placed sufficient value on water resources.

66.We can conclude from the passage that the water problem______.

A. is already serious in certain parts of the world

B. has been exaggerated by some experts in the field

C. poses a challenge to the technology of building reservoirs

D. is underestimated by government organizations at different levels

67.According to the author, the water price should______.

A. be reduced to the minimum

B. stimulate domestic demand

C. equal its real value

D. take into account the occurrences of droughts.

Is early childhood education really necessary? Early childhood education primarily focuses on learning through playing to develop the child’s physical, sensory, communicational and social development． Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for Kindergarten．

There are good reasons for the government to push early childhood education．Studies have shown that orphaned children who did not receive good care and education become developmentally delayed causing failure in school, and even in life．Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public help or go to jail．

There are also negative parts to putting a child in formal education programs too early．Time Magazine online explains that “the younger the child the less his chances of catching up with first-grade work．” I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school．Yet parents have been sure that the earlier the child starts school, the better off he or she is, so they push to start children earlier．

Actually while early formal education of poor children does show great gains in the early elementary years, studies also show that this head start is really a “false start”, as the gains are lost in middle and high school years．It seems that environment is a bigger factor on life’s success than early education．Head Start programs have not achieved its original goal in closing the achievement gap in poor and middle school children．Perhaps it is time to find other ways to close that gap．

The purpose of the government valuing the early childhood education is ________．

    A．to develop the children’s communication

    A．to give orphaned children good care and education

    C．to get the children prepared for the kindergarten

    D．to train the children formally and regularly

According to the studies, which of the following is True?

    A．Children with good early education may have a rich life．

    B．The orphaned children are usually unhappy in their life．

    C．Children without early education can do well at school．

    D．Head Start programs are helpful to the poor children．

The author’s attitude toward the early childhood education is _________．

    A．puzzling     B．objective   C．indifferent      D．a(chǎn)pproving

The main idea of the last passage is that __________．

    A．the early childhood education is very necessary

    B．Head Start programs have helped the children a lot

    C．environment is the most important to life’s success

    D．better ways should be found to help the poor children
