You might like to try one of these four experiences. Crocodile watching Do you fancy getting up close to some of the most terrifying animals on earth? Crocosaurus Cove, in Darwin (Australia) has the “Cage of Death”. Its an enclosure thats lowered into a pool. This gives you a 360 degree view of a crocodile as its being fed. The cable broke once and the cage sank to the bottom, but theyve fixed it since then. EdgeWalk How about walking along the edge of a building several hundred meters up in the air? If that sounds like fun, head off to the CN Tower in Toronto (Ontario, Canada). Built in 1976, the tower is 553.33 meters tall. The EdgeWalk consists of a 20-30 minute stroll along a 1.5 meter wide platform that runs around the towers restaurant roof. During the walk, youre encouraged to lean forwards as you look over Torontos skyline (轮廓线). Plastic ball rolling Do you fancy rolling down a hill in a plastic ball? Plastic ball rolling is popular all over the world, but the place to give it a go is in Rotorua (New Zealand). Brother David and Andrew Akers came up with the idea in 1994. A typical orb (球) is about 3 meters in diameter, with an inner orb size of about 2 meters. Theres no brake or steering mechanism, but the inner layer of the plastic ball helps absorb the shock. Volcano bungee jumping If youre looking for the adventure of a lifetime, how about going bungee jumping off a helicopter into the crater of a live volcano? As part of the jumping, a helicopter ride takes you to the Villarrica volcano, one of the most active in Chile. Once youre at the drop zone, you leap off the helicopter and fall into the volcano. Finally, you enjoy the ride back to the airport flying at 130kph. Attracted by the above? If so, please contact us.

It can be inferred that all the four experiences are _.A. interesting sports B. exciting and extremeC. held on high places D. fit for middle to old peopleB If you want a little extra security against thieves stealing your bicycle, designer Dennis Siegel has designed a solution. The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement. “The RFID Bikealarm is meant to be a useful add-on to mechanical bicycle locks because it greatly extends the range of protection with only a few components,” Siegel explains on his website. “It is low-cost, durable and easy to use.” The Bikealarm was designed as part of Siegels Bachelors degree thesis at the University of the Arts Bremen in Germany. The device will scare off any would-be thieves the moment they begin to steal the bicycle to which it is attached. It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram / car and a serious theft. Siegel created a working model of an alarm that would sound when it sensed movement, but wasnt initially sure how it would be best attached to a bicycle. “I decided to mount it to the rails of the seat because it allows for comfortable interaction and the position is less obvious as it looks like a small repair kit,” he says. Siegel chose to use RFID technology rather than Bluetooth to keep the costs down. Siegel explains that the most difficult aspect of creating the alarm was to get the electronic circuit down to a small enough size. The device runs off a kind of battery that can be charged by USB within 2 hours and lasts for a few days with normal use. As the Bikealarm is only at development stage, Siegel hasnt signed any agreements to put it on the market.4. When it senses movement, the RFID Bikealarm will _.A. make a warning sound B. fasten the bicycle tightlyC. shake the bicycle quickly D. call the police automatically5. Which of the following shows the right position of the RFID Bikealarm on a bicycle?6. What do we know about the RFID Bikealarm?A. It cant tell between specific events. B. It is very difficult to use.C. It uses a kind of battery for power. D. It depends
