Question

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 soundB. fasten the bicycle tightly

C. shake the bicycle quicklyD. call the police automatically

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

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

Answer

3.C

4.D

【解析】

试题分析：文章介绍了一种防止自行车被盗的警报器，以及一些具体的发明细节。

1. 细节推理题。根据第一段The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.可知，自行车感觉到振动时会发出警报，故选A。

2. 细节推理题。根据第一段The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.和第四段“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,”可知，警报器是和自行车座位相连接的，故选B。

3. 细节推理题。根据第三段It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram / car and a serious theft.可知，A错误；根据第二段“It is low-cost, durable and easy to use.”可知，B错误；根据最后一段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.可知，C正确；根据倒数第二段Siegel chose to use RFID technology rather than Bluetooth to keep the costs down.可知，D错误。故选C。

4. 推理判断题。根据最后一段As the Bikealarm is only at development stage, Siegel hasn’t signed any agreements to put it on the market.可知，这种设备现在还是开发阶段，Siegel还没有签协议投放市场。故选D。

做好细节理解题的几点建议：

细节理解题属直接解答性问题，是阅读理解题中最简单的一种，多数属中低难度的题。但高考所占的比例大，应特别引起注意。事实和细节题的命题特点是：对文章或某一段落中的一些特定细节或文章重要事实的理解，一般包括直接理解题和语义转化题。直接理解题能在原文直接找到答案，而语义转化题则需要将题目信息与原文信息加工或整理后才能得出结论。

做细节理解题具体方法与步骤如下：

①略读材料，大概了解原文，掌握中心或主旨；

②按文章的体裁，作者写作的组织模式及有关的信息词。如for example, first, second…等预测应该到何处寻找自己所需要的事实；

③将自己精力放在寻找你所需要的细节上。快速通篇跳读，全文扫视，找到细节出处，待找到含细节句子时，放慢速度，仔细核对比较内容，直至找到答案。如第4小题根据第一段The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.可知自行车感觉到振动时会发出警报，故选A.第5小题根据第一段The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.和第四段“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,”可知警报器是和自行车座位相连接的，故选B.
