第2题
The world of taxi drivers is dominated by men. But there is one small taxi company in De
lhi,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

B、causes a hot debate in India

C、was set up in 2012

D、is free of charge for women

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.

D、The background information of Cabs for Women by Women.
