    Cycling or even walking in city areas can be a little dangerous, thanks to the fact that one is sharing the road with vehicles that are increasingly getting larger and heavier. A recent study proves that of the 1.27million people that die in road traffic crashes each year, about half are walkers, motorcyclists and cyclists. Now there may be a solution that could provide at least some help to protect this helpless group---an airbag!

    If you are worried that this safety measure will involve you taking around a heavy package or worse still, wrapping yourself inside an ugly plastic bag, the bag is fitted not on the human, but on the outside of the vehicle. And, while there are several versions of the idea in the works, the one most recently unveiled by Dutch car company TNO, seems to be the most advanced and ready to go into production.

    In the works since 2011, the airbag covers only the lower part of the windshield. This will provide the much needed buffer(缓冲)between the person's head and the pane of glass he/she would otherwise meet.

    The chain of events leading to an airbag cause are quite simple---A camera fitted beneath the rear-view mirror monitors the vehicle's closeness to a walker or cyclist. Any contact with either one of them sets off the sensors in the car's bumper and quickly blows up the airbag. In addition to that the sensors also set off the car's automatic brake, reducing the chances if an even worse injury.

    In tests conducted using a model, the success of not getting injured after being hit by a car travelling at about 40km/h was about 50-50! While not perfect, it will still result in reducing the number of deaths by a huge amount.

    With TNO ready to license its technology to car makers and many more companies trying to develop similar concepts, we would not be surprised if outer airbags become a standard feature in every car pretty soon.

短文填空

    Each year {#blank#}1{#/blank#}(thousand) of tourists visit the polar regions of the Arctic and Antarctica. But the increasing number of people traveling to the ends of the Earth can have {#blank#}2{#/blank#}negative effect on fragile ecosystems. Should tourists {#blank#}3{#/blank#}(allow) to visit polar regions?

    About 40,000 tourists visit Antarctica each year. More than five million travel to the Arctic and sub-Arctic. Transporting tourists to the regions {#blank#}4{#/blank#}(increase) ship and airplane traffic, adding to the risk of pollution, oil spills, and other {#blank#}5{#/blank#}(environment) damage. Because the places where wildlife is accessible {#blank#}6{#/blank#}(be) few in number, tourist traffic can become concentrated in specific areas, {#blank#}7{#/blank#} (put)Arctic vegetation at risk.

    Others say that access {#blank#}8{#/blank#}these very special parts of the world should not be restricted to only researchers and scientists. Polar tourism allows people to develop deep  {#blank#}9{#/blank#}(person) connections with polar regions. “Those {#blank#}10{#/blank#}travel to the Arctic or Antarctica often become cheerleaders for supporting those places.” Jim Sano, vice president for travel and conservation at World Wildlife Fund, told TFK.

    Ms. Hu, I received the parcel from Scan Technology 1 piece. The scanner model they sent is correct, and the quantity is right. However, I've discovered the cables and connectors are all wrong. They are not suitable for the model 8021101.

    Can you do me a small favor and go through the product information website and see if the cables and connectors are still compatible (兼容的)with the 8021101 scanners? I have no wish to unpack the cables and connectors and try connecting them to the scanners. I believe we will have problem asking for an exchange if the cables and connectors are not compatible. If the website suggests an incompatibility, please contact Dan Richman and request an exchange for the collect model. (Refer to the invoice for his e-mail address.)

    I will only use the scanners for our project once we have resolved the exchange issue. We should not proceed unless we get confirmation (证实)on their compatibility. I am looking to resolve this in the shortest possible time as it would be disastrous to wait for this exchange without making progress on the project.
