A device that stops drivers from falling asleep at the wheel is about to undergo(接受) testing at Department of Transport laboratories and could go on sale within 12 months.

The system, called driver Alert, aims to reduce deadly road accidents by 20%--40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue（疲劳）.

Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel(方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.

Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.

In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.

The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

小题1:How should a driver respond to the sounds from Driver Alert?

A．By sounding a warning.

B．By touching the wristband.

C．By checking the driving time.

D．By pressing the steering wheel.小题2:We can learn from the text that the driver needs to stop for a break when his response time is ________

A．about 400 milliseconds

B．below 500 milliseconds

C．over 500 milliseconds

D．about 4 minutes小题3:When the driver gets sleepy while driving, Driver Alert ______.

A．moves more regularly

B．stops working properly

C．opens the window for the driver

D．sounds more frequently and loudly小题4:According to the text, Driver Alert ______.

A．aims to reduce tiredness-related accidents

B．has gone through testing at laboratories

C．aims to prevent drivers from sleeping

D．has been on sale for 12 months

判断正误。  

①《次北固山下》这首诗以第二联驰誉当时，传诵后世。(　 )   

②“潮平两岸阔”，“阔”是表现“潮平”的结果。春潮涌涨，江水浩渺，放眼望去，江面似乎与岸平了，船上的人视野也因之开阔。“风正一帆悬”，“悬”是端端直直高挂的样子。诗人不用“风顺” ，而用“风正”，因为有时风顺，却很猛，那帆就鼓成弧形了。只有顺风，又是和风，帆才能够“悬”，一个“正”字包含为“顺”与“和”的内容，表现了风平浪静的景色。(     )   

③“海日生残夜，江春入旧年”都表现了时序的交替，而且是那样匆匆不可待，这怎不叫身在“客路”的诗人生思乡之情呢？( 　)   

④“乡书何处达。归雁洛阳边”紧承三联而来，与首联遥相呼应，使全篇笼罩着一层淡淡的乡思愁绪。( 　)

一展览厅的圆弧形静定三铰拱，其跨度l=25m，矢高f=4m（见下图），在C、D、E处均作用着两个集中荷载P_gk及P_qk，即一是由永久荷载标准值产生的拱顶集中荷载P_gk=100kN，另一是由拱面活荷载标准值产生的拱顶集中荷载P_qk=50kN，由此算得该拱底部拉杆的轴向拉力设计值N_A=（）kN。三铰拱的计算简图

A.495.8

B.560.55
