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 Siegel’s Bachelor’s 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 wasn’t 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 hasn’t signed any agreements to put it on the market.

1.When it senses movement, the RFID Bikealarm will _____.

A. make a warning sound

B. fasten the bicycle tightly

C. shake the bicycle quickly

D. call the police automatically

2.Which of the following shows the right position of the RFID Bikealarm on a bicycle?

A. B.

C. D.

3. What do we know about the RFID Bikealarm?

A. It can’t tell between specific events.

B. It is very difficult to use.

C. It uses a kind of battery for power.

D. It depends on Bluetooth technology.

4. It can be inferred from the last two paragraphs that ______.

A. the electronic circuit is a little larger

B. it’s very easy to make a Bikealarm

C. it costs too much at present

D. not many Bikealarms are produced

A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.

Since it has been brought into use, its creators say more than 1000 people have drunk others’ “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.

The device was built for the United Nations’ child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.

The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.

“It uses a technique called membrane distillation (膜蒸馏),” he told the BBC. “We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person’s T-shirt typically produces 10ml, about a mouthful.”

The device has been put on show at the Gothia Cup-the world’s largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agency Deportivo, said the machine had helped raise awareness for UNICEF, but in reality had its limitations.

“People haven’t produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we’ve equipped the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”

1.Which of the following is the disadvantage of the sweat machine?

A. It takes too long for the machine to produce water.

B. The amount of water the machine produces is rather limited.

C. It costs a large amount of money to build the machine.

D. The water processed by the machine is not clean enough.

2.UNICEF is mentioned in the text to ________.

A. show how the sweat machine works

B. explain why the sweat machine was invented

C. show the importance of the United Nations

D. tell us who invented the sweat machine

3.What did Mattias Ronge think of the sweat machine?

A. It could only be used in summer.

B. It did not work at all.

C. It was not worth popularizing.

D. The water it produced tasted sweet.

4.The text is written mainly to tell us that ______________.

A. a machine which turns sweat into drinking water is invented

B. 780 million people in the world lack access to clean water

C. a better solution to purifying dirty water is discovered

D. the pill which turns dirty water into clean water is produced
