填空题

[A] The petitioners argue that repealing the tax will cost the Treasury billions of dollars in lost revenues and will result in either increased taxes in the long run or cuts to Medicare, Social Security, environmental protection and other government programs. Repealing the levy "would enrich the heirs of America’s millionaires and billionaires, while hurting families who struggle to make ends meet," the petition says.

[B] About 120 wealthy Americans had signed or supported a petition to oppose phasing out the tax. President Bush has included the repeal of the tax in his $1.6 trillion tax-cut proposal. Normally when "dozens" of Americans join in a political cause, it is not particularly noteworthy, but in this case the dozens include: George Soros, a billionaire financier; Warren Buffett, an investor listed as America’s fourth-richest person; the philanthropist David Rockefeller Jr. ; and William Gates Sr. , a Seattle lawyer and father of America’s richest man, Microsoft Corp. Chairman Bill Gates.

[C] Buffett and company cite these factors in their petition calling for opposition to the estate-tax repeal. They also discuss something that’s equally emotional and far more complex: the principle of meritocracy. The idea that everyone in America has an equal chance, that our fates are not determined by accidents of birth, is one of our core values. And nowhere is this principle more revered than in the technology economy; entrepreneurship is almost by definition an expression of meritocracy.

[D] Buffett told the Times that repealing the estate tax would be a "terrible mistake" and the equivalent of "choosing the 2020 Olympic team by picking the eldest sons of the gold medal winners in the 2000 Olympics. "

[E] An old brokerage commercial says: "He made his money the old-fashioned way: He earned it." There was a perfect parody of the ad in which the line read: "He made his money the old-fashioned way: He inherited it. " In 20 or 50 or 100 years, which of these lines will be right Buffett and Soros and friends, to their credit, want to help make the first one real. Let’s hope this is only one step in that process.

[F] It was refreshing to see Buffett and George Soros and a number of other extremely wealthy luminaries stand up in opposition to President Bush’s proposed repeal of the estate tax. While the policy has some emotional attractions—it would protect the inheritors of some small businesses from having to sell the companies to pay taxes, and it is true that most people have been taxed on their savings once already—in practice the tax repeal would mainly be a windfall for a very small number of very, very rich people.

[G] President will make his case for his $1.6 trillion tax cut plan, delivering a speech at a community center in St. Louis. The proposal would slash federal tax rates across all levels of income, eliminate the so-called marriage penalty and phase out estate taxes. Democrats complain that the plan—which would cut the top rate from 39 to 33 percent—would disproportionately benefit the wealthy and unnecessarily squander expected budget surpluses. Some of the richest Americans are urging Congress not to repeal the estate tax, The New York Times reported on Wednesday. (Feb. 14)

言葉は時代に伴って進化する。ほかの言語と同様に今まで日本語もずっと変化し続けてきたが、現在は特に猛烈なスピードで変化しているようだ。その原因のひとつとして考えられるのは、いわゆるITに関係すること、つまりパソコンや携帯電話などである。以前は専門家にしか分からなかったコンピューター用語も、今では一般の会話の中に当然のように出てくるようになった。(ア)、携帯電話やパソコンのメール、掲示板などの書き込み(跟帖)から次々と新しい言葉が生まれている。()や()のような顔文字も入り、そこでの会話はまるで宇宙人がしゃべっているように思えるくらいである。これまで多くの言葉が生まれたり消えたりしていき、残る言葉の数は限られているので、このような事態も特に驚くことではないという学者もいる。しかし、これほど新しい言葉や表現が増えると大半が消えていったとしても、かなりの数の新しい言葉が残るのではないだろうか。50年後の日本語は今とはまったく別の言葉になっているのかもしれない。というのは言い過ぎだろうか。

文中に「特に驚くことではない」とあるが、その理由はどれか()。

A.生み出された新しい言葉は思ったより多いから

B.残っていく新しい言葉の数は今までと変わらないから

C.いつの時代も若い人の会話は宇宙人の会話のようだから

D.携帯電話やパソコンの影響で新しい言葉が増えているから
