[简答题]It is just one example of the growing concern over the increasing power consumption and environmental impact of computers. A study found that the power consumption of data centers doubled between 2000 and 2005, and now accounts for 1.2% of American electricity consumption, though other estimates put the figure at 4%. Companies now spend as much as 10% of their technology budgets on energy, says Rakesh Kumar of Gartner, a consultancy.
Power consumption has increased because of the rise of the internet, of course, but also because of way in which computers have historically been designed: to maximize performance at all costs. Between 1996 and 2006, the number of servers in use went from 6 million to 28 million and the average power consumption of each server grew from 150 watts to 400 watts. But things are now starting to change and the computer industry has been seized with enthusiasm for "green computing".

[单项选择]Just over 10 years ago, Ingmar Bergman announced that the widely acclaimed Fanny and Alexander would mark his last hurrah as a filmmaker. Although some critics had written him off as earnest but ponderous, others were saddened by the departure of an artist who had explored cinematic moods -- from high tragedy to low comedy -- during his four-decade career.
What nobody foresaw was that Bergman would find a variety of ways to circumvent his own retirement -- directing television movies, staging theater productions, and writing screenplays for other filmmakers to direct. His latest enterprise as a screenwriter, Sunday’s Children, completes a trilogy of family-oriented movies that began with Fanny and Alexander and continued with The Best Intentions written by Bergman and directed by Danish filmmaker Bille August.
Besides dealing with members of Bergman’s family in bygone times--it begins a few years after The Best Intentions leaves off--the new picture was directed by Daniel Ber

[单项选择]Just over three years old and about four-feet tall. Methuselah is growing well. "It’s lovely." Dr. Sarah Sallon said of the date palm，whose parents may have provided food for the besieged Jews at Masada some 2 000 years ago. The little tree was sprouted in 2005 from a seed recovered from Masada, where rebelling Jews committed suicide rather than surrender to Roman attackers.
Radiocarbon dating of seed fragments clinging to its root, as well as other seeds found with it that didn’t sprout, indicate they were about 2 000 years old—the oldest seed known to have been sprouted and grown.
Sallon, director of the Louis L. Borick Natural Medicine Research Center at Hadassah Medical Organization in Israel, updates the saga of Methuselah in Friday’s edition of the journal Science.
One thing they don’t know yet is whether it’s a boy or girl. Date palms differ by sex, but experts can’t tell the difference until the tree is six or seven years old, Sallon said.
She hopes t
A. is an ancient tree about 2 000 years old

C. had already become extinct 2 000 years ago
D. has been the food source since 2 000 years ago

[单项选择]Dear Sir,
Just over six months ago, I saw an advertisement in a morning newspaper for a set of the complete works (全集) of William Shakespeare: Your company offered this set at a low price: 15 pounds and 50 pence. I had wanted a set of Shakespeare’s plays and poems for some time, so I sent for them.
Two weeks later, the books arrived, together with a set of the works of Charles Dickens which I had not wanted. So I returned the Dickens’ books to you. Two more weeks passed. Then there arrived a second set of the works of Shakespeare, the same set of Dickens’ books and a set of the plays of Moliere in French. I do not read French, and they were not useful at all, so I wrote to you. You did not answer that letter. Instead you sent me a bill for 42 pounds and a set of the plays of Schiller in German. I have no room for any more books, and I have no time to read them all.
Please send no more books, no more bills and no more angry letters for payment. Just send one large t
A. 15 pounds and 50 pence.
B. 42 pounds.
C. 57 pounds and 50 pence.
