???? The time capsule was buried in Aspen .Colorado .in 1983, shortly after Jobs attended the International Design Conference being held in that city. Organizers called the device the Aspen Time Tube and contributed items like Rubik's cubes(魔方) and some iconic music. Jobs added his own items to the capsule ,including the " Lisa"? ( also known as an "Apple" )"mouse he used for his presentation at the conference. '

??? Younger readers may not recognize the name but the Lisa Apple mouse was one of the first commercial mice released to consumers. The mouse was specially designed for the Apple? Lisa computer. It's also the first personal computer to offer users a graphical user interface(图形用户界面)

??? Initially ,the plan was to dig up the time capsule in the year2000,but organizers forgot its exact location. Recently .they brought in researchers working with the National Geographic Channel show Diggers to find the device. Eventually they came across the 13-foot-long.1. 5-foot-diameter tube. inside they found a lot of 1980s artifacts(人工制品）that are still being catalogued.

??? “When the end came off .literally things just poured out .”noted Diggers host Tim Saylor "There must be literally thousands of things in there.”

??? “They had the foresight to put a bunch of stuff in? plastic bags." Saylor said .“I could see at least a dozen plastic bags and other items. But I know for sure there got to be photographs in there. People had hand-written things on the back of the photographs ,so there will be some really interesting things inside.”

??? Among the artifacts researchers expect to discover inside :a Steve Jobs speech in which the Apple visionary outlines his predictions? for future technologies. We should know more about the researchers ,discoveries once the Diggers program airs this fall.

Something that has always interested me about Abraham Lincoln is，not surprisingly，his sense of humor. As far as I can tell，he's the first American President to have one．

That's because the term“sense of humor” really wasn't in common usage until the eighteen-sixties and seventies．In the eighteen-forties and fifties，it was called“the sense of the ridiculous," and didn't have the positive connotations（隐含意义）that“sense of humor" has today. Back then，what was ridiculous was what invited ridicule（讥笑）．Funniness and cruelty went hand in hand．Of course，they still do a lot of arm-in-arm walking in our day as well．

Lincoln’s humor was very different because，for one thing，it was actually "humor＂as what the word meant in his time. We don't make the distinction between "wit（风趣）”and "humor”anymore; but in the nineteenth century people did．Wit was unpleasant and offensive while humor was pleasant and sympathetic．It’s the difference we note now when we distinguish between "laughing with”and“laughing at．”Lincoln was much more about "laughing with”than "laughing at．”And when“laughing at，”it was often himself he was teasing.

In the famous Lincoln-Douglas debates，when Douglas accused Lincoln of being two-faced，Lincoln replied，referencing his plain looking，“Honestly，if I were two-faced，would I be showing you this one？”And，in a way，Lincoln's face itself tells us much about his sense of humor．

You can comb through thousands of photographs of politicians，soldiers，and the like from Lincoln's time and not find a single smile．

True, the long exposures（曝光）required for photographs of that time made smiling difficult．Yet Lincoln alone，as far as I can tell，overcame that difficulty.

Interestingly, while having a sense of humor，or at least the appearance of one provided by comedy writers has become a necessary characteristic for an American President in our time，in the nineteenth century，too much humor was considered problem. And that was the case for Lincoln．A journalist covering the Lincoln-Douglas debates commented that“I could not take a real personal liking to the man，owing to an inborn weakness. . .that he was extremely, fond of jokes，anecdotes，and stories．”

1.We can infer from Paragraph 2 that＿＿

A .the American President could influence the use of English

B. the term "sense of humor”wasn't invented until the 1860s

C .what is funny to someone might be offensive to someone else

D. the concept of humor remains the same despite the passing of time

2.The underlined words“this one”in Paragraph 4 refer to＿＿．

A. Lincoln's unattractive face

B. Lincoln's sense of humor

C. the debate they were having

D.cruelty that went with funniness

3.We rarely see people from Lincoln's time wear smile in their photos because＿．

A. being humorous was considered inappropriate

B. they found it quite funny to smile before camera

C. not smiling for photographs was the fashion

D. photography technology then was not advanced

4.What might the writer think of the journalist covering the Lincoln-Douglas debates？

A. His comment accurately reflected his time

B. He created a false picture of Lincoln

C. He was prejudiced and self-centered

D. He was brave to point out Lincoln's weakness

Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.

Green tea contains antioxidant chemicals (抗氧化物) that may help stop the cell damage that can lead to disease. Researchers have been studying green tea’s effect on everything from cholesterol (胆固醇) to the risk of certain cancers, with mixed results so far.

They found those who drank the most green tea were the least likely to develop “functional disability”, or problems with daily activities or basic needs, such as dressing or bathing.

Specifically, almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day.

The study did not prove that green tea alone kept people agile as they grew older. Green-tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a lower disability risk, the researchers said.

People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.

Although it’s not clear how green tea might offer a buffer (缓冲) against disability, Tomata’s team did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.

While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could affect drugs that prevent blood clotting (凝固).

1.What can be learned from the passage?

A．Antioxidant chemicals can lead to disease.

B．Those who often drank green tea can’t develop “functional disability”.

C．“Functional disability” is related to problems with daily activities or basic needs.

D．People who drank at least five cups a day are not likely to become functionally disabled.

2.What does the fifth paragraph mainly tell us?

A．How the study was proved. B．Why green tea-lovers can keep agile.

C．What healthier diets include. D．How to lower disability risk.

3.What have the Researchers discovered?

A．Those who drank green tea can't develop “functional disability”.

B．Green tea alone kept people agile as they grew older.

C．How green tea might offer a buffer against disability.

D．Green tea extracts (提取物) seem to increase leg muscle strength in older women.
