The world of taxi drivers is dominated by men. But there is one small taxi company in Delhi，where all the drivers and passengers are female. Women’s safety is a hot topic in India at the moment, so it's proving a very popular service.
“When I’m on the road driving our taxi I feel very proud，because this is the first taxi service only for women,” says 31yearold Shanti Sharma, who is one of eight female drivers with a taxi service called Cabs for Women by Women.
The last couple of months, since the rape and murder in the city of a college student travelling on a bus, have been particularly busy for her and her colleagues.
“After this case，our workload has increased so much,” says Sharma.“Women who used other cab services are also turning to us now.”
Most women in Delhi say they routinely face harassment(骚扰), and worse, especially on public transport.
Sharma, a single parent with three daughters, has been working as a taxi driver since 2011, when the service was first set up, and it has changed her life. This is the first time that she has earned enough—about 250 a month—to support her family.
Of course, she and the other female taxi drivers are completely outnumbered by male cabbies.“When I park somewhere there are always men there and inevitably five or six of them get together and hang out, ” she says.“I’m usually the only woman in the parking lot, so I just stay inside the car.”
It’s not much better when she is out on the road. Sharma says the male drivers give her a hard time.“As soon as they see a woman at the wheel they start honking(按喇叭) for no reason. They’ll try to overtake you. I’m always worrying about how to avoid getting hit by someone.”
The company behind Cabs for Women by Women, Sakha Consulting Wings, had a number of goals when it set up the service .It wanted to give women from poor backgrounds an opportunity to earn money. By putting women in charge of technologies, it also wanted to change people’s attitudes, and open up boundaries for women.
21、The taxi service Cabs for Women by Women _____.
A、is greatly needed at present in India

22、Why are women who used other cab services turning to Cabs for Women by Women？
A、Because it is cheap.
B、Because it is safe.
C、Because it is famous.
D、Because it is convenient.
23、What do we know about Sharma？
A、She is the first female taxi driver in Delhi.
B、She lives in harmony with her husband.
C、She has regretted becoming a taxi driver.
D、She has a better salary after becoming a taxi driver.
24、What is the main idea of the last paragraph？
A、The opportunities Cabs for Women by Women provides for women.
B、The main purposes of Cabs for Women by Women.
C、People’s attitudes towards Cabs for Women by Women.

Research findings from Norwegian and Danish scientists released in late 1997 indicate that the world's reindeer are "hot" — radioactive — and are contaminating their owners and minders.
The radiation comes as a result of the 500 atomic bomb tests carried out in the atmosphere by the nuclear nations in the 1950s and 1960s. Long-lived isotopes in the fall-out have built up in Arctic lichens which are the reindeer's staple diet. The reindeer have been found to concentrate the isotopes in their bodies. Animals are affected all over the Arctic, with the most radioactive reindeer in Canada, Alaska and Siberia's Taimyr Peninsula.
Enormous amounts of reindeer meat — some 14,000 tonnes — are eaten in the Arctic each year. Research at the Danish Riso National Laboratory has found that reindeer herders, who consume a lot of the meat, take in 300 times more radiation each year than is the average anywhere in northern Europe. Norway's Radiation Protection Authority estimates that many hundreds of herders have died of cancer as a result.
Meanwhile reindeer are emerging as one of the greatest environmental threats to the Norwegian Arctic. Over-grazing and trampling is causing more damage to the fragile tundra than pollutants from the world's worst-offending factories. Over the last 40 years the number of reindeer in the Norwegian Arctic have doubled, reaching 20 animals per square kilometre, a very high density. Research by the Norwegian and Danish geological surveys and Russia's Kola Science Centre have found that 75 percent of the moss in the Norwegian Arctic and 85 percent of lichen have been "severely damaged" by reindeer. Three-quarters of the area is suffering from soil erosion. By contrast, two of the world's most polluting factories---nickel smelters in Russia's Kola peninsula — have about 10 percent of the moss and 14 percent of the lichen in the area.
Even the Saami people, who own most of the reindeer, admit that the animals may be causing problems. Lars-Ander Baer, vice-president of their council, admitted to a conference on the Arctic environment recently: "We simply don't know how many reindeer the northern part of Norway can take."
Which of the following is NOT a cause of the problem under discussion？
A．Over-grazing.
B．Radioactive contamination.
C．Poaching.
D．Trampling.

One of the qualities that most people admire in others is the willingness to admit one's mistakes. (79) It is extremely hard some times to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that."
I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a grocery store in the neighborhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and I began to remember vaguely the incident he was de scribing.
I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular clay, I must have found my way to the dairy food department where the incident tool place.
(80) There must have been a special sale on eggs that day be cause there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together; so I went to work.
The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was culprit(罪犯). He severely scolded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not.
How old was the author when he wrote this article？
A．About 8.
B．About 18.
C．About 23.
D．About 15.

Unemployment in the state hit an all-time low of 2.1 percent this summer, the lowest in the nation. Though it has edged up a little since, it is still among the tightest labour markets in the US. And Connecticut is only the most extreme manifestation of the conditions that now prevail across America. Unemployment nationally is 4.1 percent, the lowest since 1970.
The performance of the US labour market in the late 1990s is as much a feature of the puzzlingly benign so-called New Economy.
For the past four years the US has enjoyed an average annual growth rate of 4 percent— up from an average of about 3 percent in the previous decade. Productivity improvements account for about two-thirds of that elevated output, as workers have increased their output per hour.
The rest has come from a rapid increase in the total number of workers, what economists call labour inputs. There has been a surge in new jobs—7m in the last three years—that has pushed the unemployment rate down into the uncharted territory of barely 4 percent.
Recent economic history suggests that, whenever unemployment has gone this low, the scramble for workers becomes so difficult that wages are rapidly bid up, and an inflationary spiral follows. But in the US in the past five years, wage growth has been muted. In the last year, total employee compensation in the private sector rose by just 3.3 percent, almost unchanged on the figure three years ago, when the unemployment rate was 5.4 percent.
"In some ways it's a bigger puzzle than the productivity puzzle," says Paul Krugman, professor of economics at the Massachusetts Institute of Technology. "How can we have such a low unemployment rate without an explosion of wages？"
A number of factors appear to have contributed.
In their search for workers to fill positions, companies have reached out to places they have not looked at in the past. As a result, more people are working than ever. The proportion of the population in employment reached a record high this year of more than 64 percent.
This expanded labour supply helps explain why companies have kept the lid on pay over the last few years. The availability of new sources of labour—women, retirees, college students among them—means companies may not have to give big pay rises to hire new workers. It also helps explain why the benefits of the New Economy are not always widely felt—more people seem to be working longer hours than ever.
But an expanded labour supply can only explain part of what has changed in the US in recent years. After all, unemployment—the proportion of the labour force out of work—has still declined, indicating that companies have drawn new workers not just from the pool of those not previously in the labour force, but also from the unemployed.
And yet still wage costs have remained muted.
One possible explanation is that companies have become more flexible in how they pay.
"At Newfield, we use a much broader variety of means to reward workers, including performance related pay, year-end bonuses, and extended contracts," says Mr. Ostop.
Why does Connecticut have the tightest labour market in the U. S. ？
