听力原文： As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents. The power of the school has been replaced by the home. Studies have shown that factors like child's understanding of language, his learning patterns, and his curiosity are well established before the child enters school at the age of six. Studies have also shown that even after school begins, children's achievements have been far more influenced by parents than by teachers. This is particularly true about language learning.
However, it's sad to see that so many parents are not making the most of their child's intelligence. Until recently parents had been intimidated by educators who asked them not to educate their children. But many teachers now realize that children cannot be educated only at school and parents are being asked to contribute both before and after the child enters school.
Parents have been particularly afraid to teach reading at home. Of course, children shouldn't be pushed to read by their parents, but educators have discovered that reading is best taught individually and the easiest place to do this is at home. Many four-or five-year-old children, who have been shown a few letters and taught their sounds, will spontaneously make up single words of their own with these letters even before they have been taught to read.

A．It depends on inheritance.
B．School education plays a major role.
C．It's influenced more by environment than by genes.
D．The power of parents proves to be a greater contribution.

The European Union had approved a number of genetically
modified crops until late 1998. But growing public concern
over its supposed environmental and health risks led several 【M1】______
EU countries to demand a moratorium (暂时禁止) on imports
of any new GM produce. By late 1999 there were enough such
country to block any new approvals of GM produce. 【M2】______
Last year, America filed a complaint at the WTO about the
moratorium, arguing that it was an illegal trade barrier
because there was no scientific base for it. 【M3】______
As more studies have been completed on the effects
of GM crops, the greens' case for them has weakened. 【M4】______
Much evidence has emerged of health risks from eating 【M5】______
them. And, overall, the studies have shown that the
environmental effects on modified crops are, not always 【M6】______
as serious as the greens claim. Nevertheless, environmentalists
continue to find fault of such studies and argue that 【M7】______
they are inconclusive.
While Americans seem happy enough to consume food made
from GM crops, opinion polls continue to show that European
consumers dislike the idea. Europeans seem be taking the attitude 【M8】______
which, since there remains the slightest possibility of adverse 【M9】______
consequences and since it is clear how they, as consumers, benefit 【M10】______
from GM crops, they would rather not run the risk.
【M1】

听力原文： Windbreaks are barriers formed by trees and other plants. Farmers plant these barriers around their fields to protect their land.
Windbreaks stop the wind from blowing soil away (33) . They also keep the wind from destroying or damaging crops. They are very important for protecting grain crops.
There have been studies done on windbreaks in parts of West Africa, for example. These found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection (33) .
But windbreaks seem to work best when they allow some winds to pass through them (341. If the wall of trees and plants blocks the wind completely, then violent air motions will take place close to the ground. These motions will lift soil into the air where it will be blown away.
There should be at least two lines in each windbreak. one line should be large treas. The second line, right next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are best for windbreaks.
If the quality of the land is not very good, studies have shown that one kind of tree that can grow well is the white pine (35) .
Windbreaks not only protect land and crops from the wind. Surplus trees can be cut down and used to provide wood (33) .
(34)
A．They can prevent soil from being blown away.
B．They can improve the yield of crops.
C．They can provide wood when cut down.
D．They can protect crops from the strong sunshine.
