(共15小题; 每小题2.5分, 满分37.5分）
阅读下列短文,从每题所给的A,B,C,D四个选项中选出最佳选项。
A
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.
1.What des the underlined wrd "That" in Paragraph 2 refer t?
A.Increased length f green lights.B.The shrtened traffic signal cycle.
C.Flexible timing f traffic signals.D.Smth traffic flw n the rad.
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.
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.

Space is where ur future is—trips t the Mn, Mars and beynd. Mst peple wuld think that aside frm cmets(彗星) and stars, there is little else ut there. But, since ur space jurney started we have left s much trash (垃圾) there that scientists are nw cncerned that if we dn't clean it up, we may all be in mrtal(致命的) danger.
The first piece f space junk was created in 1964, when the American satellite Vanguard I stpped perating and lst its cnnectin with the grund center. Hwever, since it kept rbiting arund the Earth withut any cnsequences, scientists became increasingly cmfrtable abandning things that served n useful purpse in space.
It is estimated (估计) that there are nw ver 500,000 pieces f man-made trash rbiting the Earth at the speed f up t 17,500 miles per hur. The junk varies frm tiny pieces f paint chipped ff rckets t cameras, huge fuel tanks, and even dd items like the millin-dllar tl kit that astrnaut Heidemarie Stefanyshyn Piper lst during a spacewalk.
The majr prblem with the space trash is that it may hit wrking satellites and damage traveling spacecraft (飞船). Mrever ,pieces f junk may cllide (碰撞) with each ther and break int pieces which fall back t the Earth. T avid this, scientists have invented several ways fr clearing the sky. Grund statins have been built t mnitr larger pieces f space trash t prevent them frm crashing int wrking satellites r space shuttles. Future plans include a cperative effrt amng many natins t stp littering in space and t clean up the trash already there.

The baby is just ne day ld and has nt yet left hspital. She is quiet but alert. Twenty centimeters frm her face researchers have placed a white card with tw black spts n it. She stares at it carefully. A researcher remves the card and replaces it by anther, this time with the spts differently spaced. As the cards change frm ne t the ther, her gaze starts t lse its fcus—until a third, with three black spts, is presented. Her gaze returns: she lks at it fr twice as lng as she did at the previus card. Can she tell that the number tw is different frm three, just 24 hurs after cming int the wrld?
Or d newbrns simply prefer mre t fewer? The same experiment, but with three spts shwn befre tw, shws the same return f interest when the number f spts changes. Perhaps it is just the newness? When slightly lder babies were shwn cards with pictures f bjects (a cmb, a key, an range and s n), changing the number f bjects was different frm changing the bjects themselves in effect. Culd it be the pattern that tw things make, as ppsed t three? N again. Babies paid mre attentin t squares mving randmly n a screen when their number changed frm tw t three, r three t tw. The effect even crsses between senses. Babies wh were repeatedly shwn tw spts became mre excited when they then heard three drumbeats than when they heard just tw; likewise when the researchers started with drumbeats and mved t spts.

Radar is an electrnic device that detects planes, ships, castlines, landmarks, and even strm cluds. The name radar cmes frm the first letters f the wrds "radi directin and ranging". As the human eye uses light waves t see, radar "sees" with radi waves. Withut radar, planes culd nt land safely in bad weather and ships culd nt mve safely in thick fg. ①_________
In the 1800s it was discvered that radi waves culd be reflected frm bjects. But scientists did nt make great advances in radar research until the 1930s, when the wrld was threatened by war. ②__________ It has been used widely in almst every cnflict(冲突) since then.
Eches make it pssible fr radar t wrk. When a beam f radi waves is sent ut, it strikes an bject and returns an ech. This ech is picked up by radar and recrded n a screen similar t televisin screens. On the screen an bserver sees a flash and that can shw the directin and distance f the bject. ③___________
Airprt cntrl twers use radar t guide planes in fr safe landings. Almst all large ships depend n radar t prevent cllisins with icebergs r ther ships. ④___________ Weather frecasters "see" the size, directin, and speed f strms n radar screens. Astrnmers can even use radar t measure accurately the distance frm the earth t the mn. Thus, the device has helped achieve majr advancements.
⑤___________It guards us against pssible enemy attacks. We have ballistic missile(弹道导弹) warning systems that can warn us against attacks when missiles are mre than 1,000 miles away. Other radar systems can als warn us against enemy aircraft and even spying space satellites.
A.The measurement is nw highly accurate.
B.Plice track speeders in radar-equipped cars.
C.The device can be used in a wide range f fields.

4. 细节理解题。由最后一段第四句可知科学家们已经建立地面观测站来监控大型的太空垃圾，所以选C。科学家们建立地面观测站来监控大型太空垃圾，而不是存放太空垃圾，所以A项错误。由最后一段最后一句可知科学家们希望未来许多国家合作停止对太空的污染并且清除掉已经在那儿的垃圾，所以B项和D项错误。
D.答案：1-4 BACD
解析：1.细节理解题。通过阅读第一段的内容可知，研究人员在婴儿眼前摆放带有不同数目黑点的卡片，以测试婴儿对数量的视觉反应。因此本段是对孩子的视觉实验，故选B。
2.细节理解题。根据第二段倒数第三句可知，当屏幕上方块的数量从2变成3，或从3变成2时，婴儿会更注意屏幕上随机移动的方块。因此，婴儿对物品的数量变化更敏感，故选A。
3.细节理解题。根据第二段倒数第一、二句可知，这种效果甚至在不同的感官之间转换。那些被反复展示两个点的婴儿在听到三个鼓点时比只听到两个鼓点时更兴奋。因此，研究者在进一步做实验，故选C。
4.推理判断题。纵观文章，文章主要讲述了对刚出生一天的婴儿做实验，通过变化纸上的黑点及鼓的敲打次数对婴儿的视觉、听觉进行的一个实验，所以这篇文章最有可能出自一篇科学报告，而非科幻小说、儿童文学或广告，故选D。

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.
1.What des the underlined wrd "That" in Paragraph 2 refer t?
A.Increased length f green lights.B.The shrtened traffic signal cycle.
C.Flexible timing f traffic signals.D.Smth traffic flw n the rad.
2.What des Kevin Balke say abut adaptive signals?
A.They wrk better n brad rads.B.They shuld be used in ther cities.

Space is where ur future is—trips t the Mn, Mars and beynd. Mst peple wuld think that aside frm cmets(彗星) and stars, there is little else ut there. But, since ur space jurney started we have left s much trash (垃圾) there that scientists are nw cncerned that if we dn't clean it up, we may all be in mrtal(致命的) danger.
The first piece f space junk was created in 1964, when the American satellite Vanguard I stpped perating and lst its cnnectin with the grund center. Hwever, since it kept rbiting arund the Earth withut any cnsequences, scientists became increasingly cmfrtable abandning things that served n useful purpse in space.
It is estimated (估计) that there are nw ver 500,000 pieces f man-made trash rbiting the Earth at the speed f up t 17,500 miles per hur. The junk varies frm tiny pieces f paint chipped ff rckets t cameras, huge fuel tanks, and even dd items like the millin-dllar tl kit that astrnaut Heidemarie Stefanyshyn Piper lst during a spacewalk.
The majr prblem with the space trash is that it may hit wrking satellites and damage traveling spacecraft (飞船). Mrever ,pieces f junk may cllide (碰撞) with each ther and break int pieces which fall back t the Earth. T avid this, scientists have invented several ways fr clearing the sky. Grund statins have been built t mnitr larger pieces f space trash t prevent them frm crashing int wrking satellites r space shuttles. Future plans include a cperative effrt amng many natins t stp littering in space and t clean up the trash already there.

As the cards change frm ne t the ther, her gaze starts t lse its fcus—until a third, with three black spts, is presented. Her gaze returns: she lks at it fr twice as lng as she did at the previus card. Can she tell that the number tw is different frm three, just 24 hurs after cming int the wrld?
Or d newbrns simply prefer mre t fewer? The same experiment, but with three spts shwn befre tw, shws the same return f interest when the number f spts changes. Perhaps it is just the newness? When slightly lder babies were shwn cards with pictures f bjects (a cmb, a key, an range and s n), changing the number f bjects was different frm changing the bjects themselves in effect. Culd it be the pattern that tw things make, as ppsed t three? N again. Babies paid mre attentin t squares mving randmly n a screen when their number changed frm tw t three, r three t tw. The effect even crsses between senses.

Radar is an electrnic device that detects planes, ships, castlines, landmarks, and even strm cluds. The name radar cmes frm the first letters f the wrds "radi directin and ranging". As the human eye uses light waves t see, radar "sees" with radi waves. Withut radar, planes culd nt land safely in bad weather and ships culd nt mve safely in thick fg. ①_________
In the 1800s it was discvered that radi waves culd be reflected frm bjects. But scientists did nt make great advances in radar research until the 1930s, when the wrld was threatened by war. ②__________ It has been used widely in almst every cnflict(冲突) since then.
Eches make it pssible fr radar t wrk. When a beam f radi waves is sent ut, it strikes an bject and returns an ech. This ech is picked up by radar and recrded n a screen similar t televisin screens. On the screen an bserver sees a flash and that can shw the directin and distance f the bject. ③___________
Airprt cntrl twers use radar t guide planes in fr safe landings. Almst all large ships depend n radar t prevent cllisins with icebergs r ther ships. ④___________ Weather frecasters "see" the size, directin, and speed f strms n radar screens. Astrnmers can even use radar t measure accurately the distance frm the earth t the mn. Thus, the device has helped achieve majr advancements.
⑤___________It guards us against pssible enemy attacks. We have ballistic missile(弹道导弹) warning systems that can warn us against attacks when missiles are mre than 1,000 miles away. Other radar systems can als warn us against enemy aircraft and even spying space satellites.
