6、ington, generally dont flash the same length of green twice in a row, especially at rush hour. At 9:30 am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33 am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37 am could push it down to 135. Just like
7、 the traffic itself, the timing of the signals changes. That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signal
8、s, have led to significant declines in both the trouble and cost of travels between work and home. Adaptive signals can make sure that the traffic demand that is there is being addressed, says Alex Stevanovic, a researcher at Florida Atlantic University. For all of Bellevues success, adaptive signal
9、s are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a
10、 meaningful difference. Its not going to fix everything, but adaptive signals have some benefits for smaller cities, he says. In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffi
11、c: just widen the roads, says Mark Poch, the Bellevue Transportation Departments traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.1.What does the underlined word That in Paragraph 2 refer to?A.Increased leng

14、ed by nature to create the first robotic fly. The fly has become a platform for a series of new high-tech systems. _(design) to do what a fly does naturally, the tiny machine is _ size of a fat housefly. Its mini wings allow it _(stay) in the air and perform controlled flight tasks. It is extremely
15、_(importance) for us to think of this as a whole system and not just the sum of a bunch of individual _(part), said Robert Wood, the Harvard engineering professor who _(work) on the robotic fly project for over a decade. A few years ago, his team _(get) the permission to start putting together the p
16、arts. The added difficulty with a project like this is that actually none of those parts is ready to use and so we have to develop them all _ our own, he said. They designed a series of systems to start and drive the robotic fly. The seemingly simple system _ just moves the wings has plenty of inter
17、dependency on the individual parts, said Wood. Although this first robotic fly is linked to a small, off-board power source, the goal is _(final) to equip it with a built-in power source, so that it might someday perform data-gathering work on rescue sites, in farmers fields or on the battlefield.答案

21、 switch to adaptive signals has been a lesson in the value of welcoming new approaches可推知, 从Bellevue装可调节式交通信号灯一事上不难发现, 它的成功在于积极尝试新事物, 故选A项。 四、答案:Designed; the; to stay; important; parts; has been working; got; on; which/that; finally解析:考查非谓语动词。主语the tiny machine与design之间为逻辑上的动宾关系,故用过去分词作状语。 考查冠词。the
22、 size of. = the same size as., 意为“和一样大”,故用定冠词the。 考查非谓语动词。allow sb./sth. to do sth.表示“允许某人/某物做某事”。 考查形容词。此处是It is + adj. + for sb.+to do sth.句塑,故用所给词的形容词形式。 考查名词复数。由空前的a bunch of可知,此处应用名词的复数形式。 考查时态。根据语境及时间状语for over a decade可知,此处表示一个从过去某个时间开始,延续到现在,并可能延续下去的动作,故用现在完成进行时。 考查时态。由时间状语A few years ago可知, 此处应用一般过去时。 考查介词。on ones own表示“独自地”,为固定搭配。 考查定语从句空处指代先行词system并在定语从句中作主语,故填which/that。 考查副词。分析句子结构可知,空处作状语,故应用副词finally。
