[单项选择]A "greenhouse effect" will raise the earth’’s temperature enough by the year 2100 to cause dramatic climate changes, increase sea levels and disrupt food production, United States scientists said this week.
The earth’’s atmosphere is heating at a rate that could mean temperature rises of two degrees centigrade by the middle of the 21st century and five degrees centigrade by the year 2100, according to a report issued by the US government’’s Environmental Protection Agency (EPA).
"Substantial increases in global warming may occur sooner than most of us would like to believe," the EPA said.
The agency said the first effects might be felt as early as 1990, because temperatures would be rising more than seven times faster each decade between now and the year 2100 than they had been for the past 100 years.
"Temperature increases are likely to be accompanied by dramatic changes in precipitation and storm patterns and a rise in global average sea level," the EPA report said.
"A

吃鱼为什么使人聪明呢这是高不饱和脂肪酸的作用。鱼的DHA含量高,特别是鱼头、鱼眼中的DHA高达40%~70%。DHA对神经细胞,特别是轴突之生长、网络之形成极其有益,因此对健脑益智有明显作用。据专家研究报告,婴儿在出生后不久脑细胞即达140亿个。此后无论脑细胞的数量及体积都不再增加。这些突起在脑神经间形成细密的网膜。而这些网膜主要由脂肪构成。人脑的脂肪占脑的60%,这就是鱼油、核桃、芝麻的不饱和脂肪酸健脑益智的道理。在脑与身体其他器官相比有共性,也有自己的特点。谈共性,即它需要各种营养素,除了高不饱和脂肪酸外也需要蛋白质、矿物质、微量元素。但它需要的脂肪酸不足,则影响智力的_________,不能从儿童的大脑转变为成人的大脑,其智力将停留在儿童的阶段。所以泡饭加咸菜的早餐既不能满足儿童对热量的要求,也不能满足儿童长身体的要求,更不能满足儿童发展智力的要求。

Charley Foley calls into the Mater Misericordia Hospital to visit his wife.
"How are you feeling" he asks, sitting at the bedside, close to Dolly who is smiling up at him, her black hair resting against the white pillows.
"I’m fine," Dolly says, quietly. She looks old and tired to Charley; she is deathly pale and has black pouches under her eyes. When she slips her fingers into Charley’s he notices two ugly brown liver spots on the back of her small hand.
"You look tired," Charley says. " Aren’t you sleeping"
"I was a bit restless last night. "
Dolly does not mention the pain: she doesn’t want to upset her husband.

[单项选择]About three-quarters of Americans, according to surveys, think the country is on the wrong track. About two-thirds of the public disapprove of the job performance of President Bush, and an even higher number disdain Congress. The media are excited about the prospect of a wealthy businessman running for President as an independent who could tap into broad public disgruntlement with the partisan politicians in Washington.
2007 Yes. But also 1992. The main difference between the two situations is that Michael Bloomberg is richer—and saner—than Ross Perot. But one similarity might be this: the American people were wrong then and may be wrong now. The widespread pessimism in the early 1990s about the course of the country turned out to be unwarranted. The rest of the decade featured impressive economic growth, a falling crime rate, successful reform of the welfare system and a reasonably peaceful world. Perhaps the problems weren’t so bad in the first place, or perhaps the political sy

Why do men die earlier than women The
latest research makes it known that the reason could be that men’s hearts go
into rapid decline when they reach middle age. The largest study
of the effects of aging on the heart has found that women’s {{U}}longevity{{/U}} may
be linked to the fact that their hearts do not lose their pumping power with
age. "We have found that the power of the male heart falls by
20—25 percent between 18 and 70 years of age," said the head of the study, David
Goldspink of Liverpool John Moores University in the UK. "Within
the heart there are millions of cells that enable it to beat. Between the age of
20 and 70, one-third of those cells die and are not replaced in men," said
Goldspink. "This is part of the aging process." What surprises
scientists is that the female heart sees very A. health B. long life C. aging D. effect
