7．London started its first major bike hire scheme （方案） on July 30th．Transport For London （TFL），the agency responsible for moving people around England's capital，put 5，000bicycles in 400different places around the city．
The idea is to cut traffic，reduce pollution and provide a greener way of getting around London's streets．The scheme had a few small problems on its first day as people could not lock the bikes properly once they had finished riding them．As a gesture of goodwill，London Mayor Boris Johnson announced all rentals （租金） on the first day would be free of charge．The bikes are available for free for the first 30minutes but costs go up sharply since then．Renters have to pay﹩1.60for the first hour and﹩78for 24hours．The bikes are clearly designed for very short trips．
TFL says it sees a"cycle revolution"happening in London．It predicts there will be around 40，000new cycle journeys every day on the rental bikes．Mr．Johnson says he wants to see a return to the turn of the 20th century，when 20per cent of journeys in London were made by bicycle．The scheme has received a lot of positive feedback （反馈） in the first two days．
Many Londoners believe it is a great alternative （替代品） to London's overcrowded and overpriced trains and buses．One person，Andy Clark，told the Reuters news agency，"It's a great idea．I've seen it operating in Paris and Barcelona and thought why don't we have one？"The Londonist Blog said the bikes were very strong and were"designed to bear a beating from both careless cyclists and drunken people"．

2．Humans not only enjoy eating ice cream，but they enjoy feeding it to their pets as well．Market studies show two thirds of all dog owners give ice cream to their dogs．Unfortunately，says William Tyznik，an expert on animal nutrition at Ohio State University，ice cream is not good for dogs．"It has milk sugar in it，"he says，"which dogs cannot digest very well．
Bothered by that knowledge but aware of the desire of dog owners to please their companions，Tyznik invented a new frozen treat for dogs that，he says，is more nutritious than ice cream-and as much fun to eat．The product，called Frosty Paws，is made of a liquid byproduct of cheese and milk with the sugar removed．Frosty Paws also contains refined soy flourwater，vegetable oil，vitamins and minerals．It took Tyznic，who has also invented a horse feed （called Tizwhiz） and another dog food （named Tizbits ），three years to perfect the Frosty Paws formula （配方），and two attempts to commercialize it．After losing $ 25，000trying to market the invention himself，Tyznik sold the rights to Associated Ice Cream of Weatervile，Ohio，which makes the product and packages it in cups．
Tyznik claims that Frosty Paws has been tested extensively and that"dogs love it"．Of 1，400dogs that have been offered the product，he says，89percent took it on the first try．Three out of four preferred it to milk，bone or sausages．The product，which will be available in the ice-cream section of supermarkets，comes in packs of three or four cups，costing between    1.39and    1.79．
What would happen if a human should mistake Frosty Paws for real ice cream？Nothing，says Tyznik．It's harmless，but frankly，he says，it won't taste very good．
