Researchers frm Gergia Tech say that they have cme up with a lw-cst device(装置)that gets arund this prblem: a smart keybard. This smart keybard precisely measures the cadence(节奏)with which ne types and the pressure fingers apply t each key. The keybard culd ffer a strng layer f security by analyzing things like the frce f a user’s typing and the time between key presses. These patterns are unique t each persn.

The traffic signals alng Factria Bulevard in Bellevue, Washingtn, generally dn’t flash the same length f green twice in a rw, especially at rush hur. At 9: 30 am, the full red/yellw/green signal cycle might be 140 secnds. By 9: 33 am, a burst f additinal traffic might push it t 145 secnds. Less traffic at 9: 37 am culd push it dwn t 135. Just like the traffic itself, the timing f the signals changes.
That is by design. Bellevue, a fast-grwing city just east f Seattle, uses a system that is gaining ppularity arund the US: intersectin (十字路口) signals that can adjust in real time t traffic cnditins. These lights, knwn as adaptive signals, have led t significant declines in bth the truble and cst f travels between wrk and hme.
“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanvic, a researcher at Flrida Atlantic University.
Fr all f Bellevue’s success, adaptive signals are nt a cure-all fr jammed radways. Kevin Balke, a research engineer at the Texas A&M University Transprtatin Institute, says that while smart lights can be particularly beneficial fr sme cities, thers are s jammed that nly a sharp reductin in the number f cars n the rad will make a meaningful difference. “It’s nt ging t fix everything, but adaptive signals have sme benefits fr smaller cities, ” he says.
In Bellevue, the switch t adaptive signals has been a lessn in the value f welcming new appraches. In the past, there was ften an autmatic reactin t increased traffic: just widen the rads, says Mark Pch, the Bellevue Transprtatin Department’s traffic engineering manager. Nw he hpes that ther cities will cnsider making their streets run smarter instead f just making them bigger.
【文章大意】美国华盛顿州贝尔维尤市的交通信号灯可以根据交通流量变化时间。
1. What des the underlined wrd “That” in Paragraph 2 refer t?
A. Increased length f green lights.
B. Shrtened traffic signal cycle.
C. Flexible timing f traffic signals.
D. Smth traffic flw n the rad.
【解析】选C。推理判断题。That指的是第一段中提到的交通信号灯的时间可以调节变换这件事。故选C。
2. What des Kevin Balke say abut adaptive signals?
A. They wrk better n brad rads.
B. They shuld be used in ther cities.
C. They have greatly reduced traffic n the rad.
D. They are less helpful in cities seriusly jammed.
【解析】选D。细节理解题。根据第四段Kevin Balke的话可知, 他认为, 虽然智能信号灯对于一些城市, 尤其是小城市有帮助, 但对于非常堵塞的城市来说, 作用不是很大, 他认为这些过度堵塞的城市需要的是路上车辆的锐减。故选D。
3. What can we learn frm Bellevue’s success?
A. It is rewarding t try new things.
B. The ld methds still wrk tday.
C. It pays t put thery int practice.
D. The simplest way is the best way.
【解析】选A。推理判断题。根据最后一段的In Bellevue, the switch t adaptive signals has been a lessn in the value f welcming new appraches. 可知, 转换为可调节的信号灯在获得新方法的价值方面给我们上了一堂课。由此可知, 尝试新事物是值得的。故选A。
【难句剖析】
Adaptive signals can make sure that the traffic demand that is there is being addressed.
分析: make sure后面是that引导的宾语从句, 在宾语从句中that is there是定语从句修饰the traffic demand。
翻译: 变化的信号灯能确保那里现有的交通需求得到满足。
