In a great many cities, hundreds of people ride bicycles to work everyday. In New City, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bicycles to work, there would be fewer automobiles(汽车) in the downtown part of the city and so less dirty air from car engines. For several years this group has been trying to get the city government to help bicycle riders. For example. They want the city to draw special lanes(通道) for bicycles only on some of the main streets, because when bicycle riders must use the same lanes as cars, there are accidents. Bike for a Better city feels that if there were special lanes more people would use bikes.
But no bicycles lanes have been drawn. Not everyone thinks they are a good idea-----they say it will slow traffic. Some store owners on the main streets don't like the idea------they say that if there is less traffic, they will have less business.
The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park----the largest place of open ground in New York----is closed to cars, and the roads may be used by bicycles only. But Bike for a Better City says that this is not enough and keeps fighting to get bicycle lanes downtown.

C. because most people travel by train D. because Bike for a Better City is not strong enough
Mozilla has shown off a prototype(雏形) for a $25 (£15) smart phone that is aimed at the developing world.
The company, which is famed mostly for its Firefox browser(浏览器), has partnered with the Chinese low-cost chip maker Spreadtrum.
While not as powerful as more expensive models, the phone will run apps and make use of mobile internet.
It would appeal to the sorts of people who currently buy cheap “feature” phones, analysts said.
Feature phones are highly popular in the developing world as a halfway point between “dumb” phones --- just voice calls and other basic functions --- and fully-developed smart phones.
Mozilla hopes that it will take an early lead in a market that is now being targeted by mobile phone producers who see the developing world as the remaining area for massive growth.
It will face fierce competition from bigger, more popular brands, however --- with more announcements of this kind expected over the course of the next couple of days at the Mobile World Congress in Barcelona.
“These solutions expand the global accessibility of open web smart phones to first-time and entry-level smart phone buyers by reducing the time and cost required for handset makers to bring these phones to market,” said Spreadtrum in a press statement.
Mozilla said the phone “redefines”(重新定义) the entry-level phone market.
The concept of a cheap smart phone may seem likely to appeal to consumers in developed countries, particularly those who locked into long contracts in order to pay part of the cost of the likes of the Apple iPhone and Samsung Galaxy range.
But analyst Carolina Milanesi, from Kantar World panel, said it should not be seen as a competitor.Which of the following is true about the $25 smart phone?
| A．It has all the functions of an iPhone. |
| B．It is specially designed for the developed world. |
| C．It will attract the present “feature” phone users. |
| D．It is made by the Chinese low-cost chip maker Spreadtrum. |
What is the feature of a “feature” phone?
| A．Though cheap, it can completely replace the iPhone. |
| B．It is just used for voice calls and other basic functions. |
| C．It has nearly all the functions of a fully-developed smart phone. |
| D．Its functions are between those of a “dumb” phone and a fully-developed smart phone. |
We can learn from the text that at the Mobile World Congress in Barcelona ________.
| A．new cheap smart phones will beat high-end ones |
| B．the $25 smart phone coming from Mozilla will be the best seller |
| C．quite a few companies will announce their new cheap smart phones |
| D．Mozilla will be the only company to announce its new cheap smart phone |
Which of the following held a negative attitude towards the cheap smart phone?
| A．Mozilla. | B．Spreadtrum. |
| C．Samsung. | D．Carolina Milanesi. |
Elephants are able to differentiate between ethnicities(种族) and sexes, and can tell an adult from a child --- all from the sound of a human voice.
This is according to a study in which researchers played voice recordings to wild African elephants.
The animals showed more fear when they heard the voices of adult Masai men.
Livestock-herding Masai people do come into conflict with elephants, and this suggests that animals have adapted to specifically listen for and avoid them.
The study is published in Proceedings of the National Academy of Sciences.
Prof Karen McComb and Dr Graeme Shannon from the University of Sussex led the study. They explained that in previous research they had used similar playback experiments to show that elephants could tell --- from the sound of a lion’s roar --- whether the animal was a female or a more dangerous male.
Prof McComb wanted to find out if the animals used their very sharp sense of hearing to identify a potential danger from humans.
The scientists recorded Masai men, women and children saying, in their own language, “Look, look over there, a group of elephants is coming”.
They also recorded Kamba men saying this phrase.
While cattle-herding Masai people often come across free-ranging elephants, which can result in violent conflict, the Kamba people’s more agricultural lifestyle does not generally bring them into aggressive touch with the animals.
When the team played recordings of these different voices through a hidden loudspeaker, they found that elephant family groups reacted more fearfully in response to the voice of a Masai man, than to a Kamba man’s voice.
And the adult male Masai voices encouraged far more of these defensive reactions than the voices of women or boys.An elephant can tell a man from a woman by sense of ________.
| A．touch | B．sight | C．smell | D．hearing |
How did the researchers get to know the elephants’ special ability of identification?
| A．By observing the elephants in the zoo. |
| B．By playing voice recordings to them. |
| C．By recording the behaviours of elephants. |
| D．By communicating with them in a special way. |
We can learn from the passage that elephants are especially afraid of ________.
| A．Masai men | B．Masai women |
| C．Kamba men | D．Kamba women |
What is the best title for the passage?
| A．Elephants and human beings |
| B．Differences between human voices |
| C．Elephants recognise human voices |
| D．Elephants conflict with human beings |
Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激),” Edwards points out. “The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution.”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own.”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate to the robotic dog because it was metal and not furry,” Beck says. “But it's amazing how quickly we have given up that belief.”
“Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds.”The purpose of Beck and Edwards’ study is to ____.
| A．understand human-animal relationship |
| B．find the causes of old people’s loneliness |
| C．make lonely old people’s life better |
| D．promote the animal-assisted research |
In the research, the old people are asked to ____.
| A．note the activities of AIBOs |
| B．keep AIBOs at home for 12 weeks |
| C．analyze the collected information |
| D．record their feelings and activities |
What is the advantage of AIBO over live dogs?
| A．It can watch TV with its owner. |
| B．It can help the disabled people. |
| C．It responds to all the human orders. |
| D．It is easier to keep at home. |
The author seems to suggest that the future robotic dogs may ____.
| A．keep old people active | B．cure certain diseases |
| C．change people's beliefs | D．look more like real dogs |

Sam Berns wasn’t like any other boy. He was 17 and he had an aging disease known as progeria.
“Even though I have many difficulties in my life, I don’t want people to feel bad for me,” Sam said during a TED talk.
Progeria affects approximately one in every 4 million to 8 million newborns. Right now, there are only about 200 children living with it worldwide. The genetic(基因的) change tied to it causes those with the disease to produce the protein progerin, which blocks normal cell function.
His view on life is extremely inspiring. He had to face challenges no one else could even dream of. As children with progeria age rapidly, they suffer from a loss of body fat and hair and an inability to gain weight. That didn’t keep Sam down, though.
“All in all, I don’t waste energy feeling bad for myself,” Sam said. “I surround myself with people that I want to be with. And I keep moving forward.”
This boy from Boston was so amazing, famous people and athletes wanted to take him under their own. Last Saturday night could have been an amazing moment for Sam. One of his favorite teams, the New England Patriots, wanted to make him their honorary captain during a playoff game.
Instead, it just was’t meant to be. Sam passed away before he had a chance to stand next to his team, so they held a moment of silence before the game for him.
Sam’s unbelievable view on life, and his deep effect on others, is hard to forget. He was presented with so many challenges in life but he wasn’t afraid to face them. Be more like Sam, this wonderful teen. Surround yourself with positive people, love them and move forward.We can infer from the passage that Sam Berns was ________.
