[单项选择]When European Union (EU) leaders took delivery of Europe’s first draft of a constitution at a summit in Greece last June, it was with almost universal praise.
There was wide agreement that the text could save the EU from paralysis once it expands from 15 to 25 members next year. It would give Europe a more stable leadership and greater clout on the world stage, said the chairman of the Convention which drafted the agreement, former French President Valery Giscard d’Estaing.

Reebok executives do not
like to hear their stylish athletic shoes called" footwear for yuppies
(雅皮士，少壮高薪职业人士)". They contend that Reebok shoes appeal to diverse market
segments, especially now that the company offers basketball and children’s shoes

[填空题]
[A] After a host of experiments and years of testing they have found out: That it your vocabulary is limited your chances of success are limited. That one of the easiest and quickest ways to get a- head is by consciously building up your knowledge of words. That the vocabulary of the average person almost stops growing by the middle twenties. And that from then on it is necessary to have an intelligent plan if progress is to be made. No haphazard hit-or-miss methods will do.

Terman, of Stanford University, that a vocabulary test is as accurate a measure of intelligence as any three units of the standard and accepted Stanford-Binet I. Q. tests. The study of words is not merely something that has to do with literature. Words are your tools of thought. You can’t even think at all without them. Try it. If you are planning to go down town this afternoon you will find that you are saying to your- self: "I think I
