Text 1   In an essay entitled “Making It in America”, the author Adam Davidson relates a joke from cotton about just how much a modern textile mill has been automated: The average mill only two employees today, a man and a dog. The man is there to feed the dog is there to keep the man away from the machines.”   Davidson’s article is one of a number of pieces that have recently appeared making the point that the reason we have such stubbornly high unemployment and declining middle-class incomes today is also because of the advances in both globalization and the information technology revolution, which are more rapidly than ever replacing labor with machines or foreign worker.   In the past, workers with average skills, doing an average job,could earn an average lifestyle ,But ,today ,average is officially over. Being average just won’t earn you what it used to. It can’t when so many more employers have so much more access to so much more above average cheap foreign labor, cheap robotics, cheap software, cheap automation and cheap genius.

"I promise." "I swear to you it’ll never happen again." "I give you my word." "Honestly. Believe me." Sure, I trust. Why not I teach English composition at a private college. With a certain excitement and intensity, I read my students’ essays, hoping to find the person behind the pen. As each semester progresses, plagiarism (剽窃) appears. Not only is my intelligence insulted as one assumes I won’t detect a polished piece of prose from an otherwise-average writer, but I feel a sadness that a student has resorted to buying a paper from a peer. Writers have styles like fingerprints and after several assignments, I can match a student’s work with his or her name even if it’s missing from the upper left-hand corner.
Why is learning less important than a higher grade-point average (GPA) When we’re threatened or sick, we make conditional promises. "If you let me pass math I will…" "Lord, if you get me over this before the big homecoming game I’ll…" Once the situation is behind us, so are the promises. Human nature Perhaps, but we do use that cliché(陈词滥调) to get us out of uncomfortable bargains. Divine interference during distress is asked; gratitude is unpaid. After all, few fulfill the contract, so why should anyone be the exception. Why not
Six years ago, I took a student before the dean. He had turned in an essay with the vocabulary and sentence structure of a PhD thesis. Up until that time, both his out-of-class and in-class work were borderline passing. I questioned the person regarding his essay and he swore it was his own work. I gave him the identical assignment and told him to write it in class, and that I’d understand this copy would not have the time and attention an out-of-class paper is given, but he had already a finished piece so he understood what was asked. He sat one hour, then turned in part of a page of unskilled writing and faulty logic. I confronted him with both essays. "I promise …, I’m not lying. I swear to you that I wrote the essay. I’m just nervous today."
The head of the English department agreed with my findings, and the meeting with the dean had the boy’s parents present. After an hour of discussion, touching on eight of the boy’s previous essays and his grade-point average, which indicated he was already on academic probation (留校查看), the dean agreed that the student had plagiarized. His parents protested, "He’s only. a child" and we instructors are wiser and should be compassionate. College people are not really children and most times would resent being labeled as such… except in this uncomfortable circumstance.
The phrase "borderline passing" (Line 3, Para. 3) probably means ______.

A:fairly good B:extremely poor C:above average D:below average

? ? ? ? ? ? ? ? ? {{B}}Forty May Be the New 30 As Scientists Redefine Age{{/B}}
? ?Is 40 really the new 30? In many ways people today act younger than their parents did at the same age.
? ?Scientists have defined a new age concept and believe it could explain why populations are aging, but at the same time seem to be getting younger.
? ?Instead of measuring aging by how long people have lived, the scientists have factored in how many more years people can probably still look forward to.
? ?"Using that measure, the average person can get younger in the sense that he or she can have even more years to live as time goes on," said Warren Sanderson of the University of New York in Stony Brook.
? ?He and Sergei Scherbov of the Vienna Institute of Demography (人口统计学) at the Austrian (奥地利的) Academy of Sciences, have used their method to estimate how the proportion of elderly people in Germany, Japan and the United States will change in the future.
? ?The average German was 39.9 years old in 2000 and could plan to live for another 39.2 years, according to research reported in the journal Nature on Wednesday.
? ?However, by 2050 the average German will be 51.9 years old and will be expected to live another 37.1 years. So middle age in 2050 would occur at around 52 years instead of 40 years as in 2000.
? ?"As people have more and more years to live they have to save more and plan more and they effectively are behaving as if they were younger," said Sanderson.
? ?Five years ago, the average American was 35.3 years old and could plan for 43.5 more years of life. By 2050, the researchers estimate it will increase to 41.7 years and 45.8 future years.
? ?"A lot of our skills, our education, our savings and the way we deal with our health care depend a great deal on how many years we have to live," said Sanderson.
? ?This dimension of how many years people have to live has been completely ignored in the discussion of aging so far.
The new age concept was developed out of the notion of

A:"future years". B:"average years". C:"past years". D:"school years".

? ?Last week, US White House spokesman Tony Snow sent journalists digging for their dictionaries. He called recent criticism by the former President Bill Clinton ."chutzpah" (大胆放肆). With just one sentence, Snow managed to make headlines, a joke and a defense of President George W. Bush. Interestingly, this is how battles are fought and won in US politics - with carefully-worded one-liners (一行字幕新闻) made for TV which often lack substance and clarity (清晰度).
? ?"The amount of information that candidates attempt to communicate to people is actually getting smaller and smaller," said Mark Smith, a political science professor at Cedarville University. This has been accompanied by a changing media environment, Smith said. In 1968, the average TV or radio soundbite (演讲中的句子或短语) was 48 seconds, according to Smith. In 1996, the average soundbite had shrunk to 8 seconds. Thus, politicians wanting publicity try to make their public communication as quotable as possible.
? ?Campaigning politicians also use 30-second TV ads and clever campaign slogans to boost their messages. Republican presidential candidate John McCain rides to campaign stops in a bus named the "Straight-Talk Express". McCain hopes the name will convince voters he plans to tell people the truth - whether it’s in fashion or not. Democratic presidential candidate Hillary Clinton, on the other hand, has chosen the campaign slogan "Let the conversation begin". She hopes it will help her appear open-minded and friendly.
? ?But one-liners, TV ads and campaign slogans all have a single key ingredient: something commonly called political "spin". Brooks Jackson, a former journalist and the currant director of the non-partisan (无党派的) website FactCheck.org, calls spin "just a polite word for deception (欺骗)."

Political Spins
Last week, US White House spokesman Tony Snow sent journalists digging for their dictionaries. He called recent criticism by the former President Bill Clinton "chutzpah" (大胆放肆). With just one sentence, Snow managed to make headlines, a joke and a defense of President George W. Bush. Interestingly. this is how battles are fought and won in US politics - with carefully-worded one-liners (一行字幕新闻) made for TV which often lack substance and clarity (清晰度).
"The amount of information that candidates attempt to communicate to people is actually getting smaller and smaller," said Mark Smith, a political science professor al Cedarville University. This has been accompanied by a changing media environment, Smith said. In 1968, the average TV or radio soundbite (演讲中的句子或短语) was 48 seconds, according to Smith. In 1996, the average soundbite had shrunk (缩短) to 8 seconds. Thus, politicians wanting publicity try to make their public communication as quotable as possible.
Campaigning politicians als0 use 30-second TV ads and clever campaign slogans (口号) to boost their messages. Republican presidential candidate John McCain rides to campaign stops in a bus named the "Straight-Talk Express". McCain hopes the name will convince voters he plans to tell people the truth - whether it’s in fashion or not. Democratic presidential candidate Hillary Clinton, on the other hand, has chosen the campaign slogan "Let the conversation begin". She hopes it will help her appear open-minded and friendly.
But one-liners, TV ads and campaign slogans all have a single key ingredient: something commonly called political "spin". Brooks Jackson, a former journalist and the current director of the non-partisan (无党派的) website FactCheck.org, calls spin "just a polite word for deception (欺骗)."
"I do believe that very often politicians believe their own spin," said Jackson.
"Strong partisans suffer from a universal human tendency: They ignore the evidence that would force them into the uncomfortable position of having to change their minds and admit that they were wrong."
