问题     The European Union had approved a number of
genetically modified crops until late 1998. But grow public             【S1】______
concern over their supposed environmental and health risks led
several EU country to demand a moratorium (暂时禁止)                    【S2】______
on imports of any new GM produce (转基因农产品).
For late 1999 there were enough such countries to block any             【S3】______
new approvals of GM produce. Last year, America filed a complaint
at the WTO about the moratorium, without arguing that                   【S4】______
it was an illegal trade barrier because there is no scientific
base for it. As more studies have been completed on the                 【S5】______
effects of GM crops, the greens’ case for them has weakened.            【S6】______
Much evidence has emerged of health risks from eating them.             【S7】______
And, overall, the studies have shown that the environmental
effects on modified crops are not always as serious as the              【S8】______
greens claim. Nevertheless, environmentalists continue to find
fault of such studies and argue that they are inconclusive.             【S9】______
    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           【S10】______
the attitude which , since there remains the slightest
possibility of adverse consequences and since it is clear
how they, as consumers, benefit from GM crops, they
would rather not run the risk. [br] 【S5】
选项
答案 base→basis
解析 易混词错误。本句意为：“因为没有科学根据支持暂停(进口)”，it指the moratorium；base“基础，基地，根据地”；basis(for)“基础，基本，根据”；科学根据只能说scientific basis。有人把base后面的for改为on，应该是受到了base on这个短语的影响。
