Next year, at last, the first set of printed tables should emerge from a calculating "difference engine" built to Babbage's design. Babbage will have been vindicated. But the realization of his dream will also underscore the extent to which he was a man born ahead of his time.
The effort to prove that Babbage's designs were logically and practically sound began in 1985, when a team of researchers at the Science Museum in London set out to build a difference engine in time for the 200th anniversary of Babbage's birth in 1992. The team, led by the museum's curator of computing, Doron Swade, constructed a monstrous device of bronze, iron and steel. It was 11 feet long, seven feet tall, weighed three tons, cost around $500 000 and took a year to piece together. And it worked perfectly, cranking out successive values of seventh-order polynomial equations to 31 significant figures. But it was incomplete. To save money, an entire section of the machine, the printer, was omitted.
To Babbage, the printer was a vital part of design. Even if the engine produced the correct answers, there was still the risk that a transcription or typesetting error would result in the finished mathematical tables being inaccurate. The only way to guarantee error-free tables was to automate the printing process as well. So his plans included specifications for a printer almost as complicated as the calculating engine itself, with adjustable margins, two separate fonts, and the ability to print in two, three or four columns.
In January, after years of searching for a sponsor for the printer, the Science Museum announced that a backer had been found. Nathan Myhrvold, the chief technology officer at Microsoft, agreed to pay for its construction (which is expected to cost $373,000 with one proviso: that the Science Museum team would build him an identical calculating engine and printer to decorate his new home on Lake Washington, near Seattle). Construction of the printer will begin—in full view of the public—at the Science Museum later this month. The full machine will be completed next year.
It is a nice irony that Babbage's plans should be realized only thanks to an infusion of cash from a man who got rich in the computer revolution that Babbage helped to foment. More striking still, even using 20th-century manufacturing technology the engine will have cost over $830 000 to build. Allowing for inflation, this is roughly a third of what it might have cost to build in Babbage's day-in contrast to the cost of electronic-computer technology, which halves in price every 18 months. That suggests that, even had Babbage succeeded, a Victorian computer revolution based on mechanical technology would not necessarily have followed.
Babbage wished to build a mechanical engine because______.
A．he was very disappointed at the mathematical tables available at the time
B．he wanted to be the first man to invent a computing machine
C．he intended to make the mathematical tables flawless
D．he thought he was doing a significant work

James then asked the woman to consider a poor black mother on welfare. She already has four children and an alcoholic husband who has all but abandoned the family. Now she discovers another child is on the way. "How would you counsel that woman？" asked James.
"Have an abortion," the woman responded. "That child would have a very poor quality of life."
"I have a vested interest in your answer," James said. "The woman I described was my mother. I was the fifth of six children born into poverty. And, in case you're interested, the quality of my life is just fine!"
Kay James ______.
A．is not a black
B．is a poor black mother
C．has five brothers and sisters
D．has a hard life

When families gather for Christmas dinner, some will stick to formal traditions dating back to Grandma's generation. Their tables will be set with the good dishes and silver, and the dress code will be Sunday-best.
But in many other homes, this china-and-silver elegance has given way to a stoneware-and-stainless in formality, with dresses assumig an equally casual-Friday look. For hosts and guests, the change means greater simplicity and comfort. For makers of fine china in Britain, it spells economic hard times.
Last week Royal Doulton, the largest employer in Stoke-on-Trent, announced that it is 'eliminating 1,000 jobs--one-fifth of its total workforce. That brings to more than 4,000 the number of positions lost in 18 months in the pottery region. Wedgwood and other pottery factories made cuts earlier.
Although a strong pound and weak markets in Asia play a role in the downsizing, the layoffs in Stoke have their roots in earthshaking social shifts. A spokesman for Royal Doulton admitted that the company "has been somewhat slow in catching up with the trend" toward casual dining. Families eat together less often, he explained, and more people eat alone, either because they are single or they eat in front of television.
Even dinner parties, if they happen at all, have gone casual. In a time of long work hours and demanding family schedules, busy hosts insist, rightly, that it' s better to share a takeout pizza on paper plates in the family room than to wait for the perfect moment or a "real" dinner party. Too often, the perfect moment new ex comes. Iron a fine-patterned tablecloth？ Forget it. Polish the silver？ Who has time？
Yet the loss of formality has its down side. The fine points of etiquette that children might once have learned at the table by observation or instruction from parents and grandparents (" Chew with your mouth dosed." "Keep your elbows off the table.") must be picked up elsewhere. Some companies now offer etiquette seminars for employees who may be competent professionally but clueless socially.
The trend toward casual dining has resulted in （）．
A.bankruptcy of fine china manufacturers
B.shrinking of the pottery industry
C.restructuring of large enterprises
D.economic recession in Great Britain

阅读理解：阅读下面的短文，根据文章内容进行判断，正确写“T”错误写“F”。
QUESTIONNAIRESA、ADVANTAGES & DISADVANTAGES
Every coin has two sides and questionnaires are no different. With questionnaires, the advantages outweigh the disadvantages.
ADVANTAGES OF QUESTIONNAIRES
Compared to face-to-face interviews, questionnaires are cheaper for
collecting data from a large number of respondents. Also, questionnaires are easy to analyze, and computer software can easily complete data entry and make tables for nearly all surveys. Questionnaires are familiar to most people as nearly everyone has had some experience completing one. Questionnaires reduce bias when there are no clues to affect the respondents.
DISADVANTAGES OF QUESTIONNAIRES
One main disadvantage of questionnaires is the possibility of low response rates which reduces our confidence in the results. Another disadvantage is they provide little flexibility for the respondents. What’s more, many times the respondent is not the same person you sent the
questionnaire to. Finally, questionnaires are not suitable for some people. For example, a survey to a group of poorly educated people might not work because of reading problems.
1. The advantages of questionnaire are more than disadvantages.{T、F}
2. Questionnaire is the cheapest way for collecting data from respondents.{T、F}
3. Questionnaires have the advantage of being analyzed easily through the computer software.{T、F}
4. Questionnaire is suitable for everyone.{T、F}
5. The respondent is usually the same person you sent the questionnaire to.{T、F}
