閱讀理解：

　　A device that stops drivers from falling asleep at fine wheel is about to undergo 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．

　　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(方向盤)．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 1aboatories for testing．If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year．

推理題。從第二段的第一句話可知。

(2)

猜詞題。第三段中指出這種裝置在旅途中每4分鐘發(fā)出一種聲音，在每個(gè)聲音過后司機(jī)必須通過擠壓方向盤來做出回應(yīng)。

(3)

細(xì)節(jié)題。從第四段的第二句可知。

(4)

細(xì)節(jié)題。從第五段的大意可知。即：如果司機(jī)的回復(fù)繼續(xù)減慢，此裝置會(huì)更頻繁地提示，直到司機(jī)盡快地停車。


提示：

本文介紹的是一種叫Driver Alert的裝置正處在檢測(cè)階段并將在一年內(nèi)投入市場(chǎng)。這種裝置的目的是減少司機(jī)在駕車過程中由疲勞所引起的交通事故。其方法是：通過車輛在行駛時(shí)每4分鐘發(fā)出一種聲音而使司機(jī)必須及時(shí)做出反應(yīng)的方法來阻止司機(jī)睡著。如果沒有及時(shí)得到司機(jī)所做出的回應(yīng)，它將會(huì)更頻繁更大聲的提示，直到司機(jī)打開窗戶或停下來休息。

閱讀理解:閱讀下列短文, 從所給的四個(gè)選項(xiàng)中, 選出最佳答案。 

    Animals seem to have the sense to eat when they are hungry and　　 they do not eat more than their bodies need. It has been demonstrated　　 (證實(shí)) that rats will, when given a choice over a period of time,　　 prefer water with vitamins (維生素) to water without vitamins, even　　 though there is no difference in taste or smell between the two water　　 bottles. When a fragrant flavor (香味) was added to the　　 vitamin—enriched liquid, the rats did seem to develop a taste for it　　 and kept drinking it, even after the vitamins were switched (轉(zhuǎn)) to　　 the clear water. In time, however, they broke the habit and went back　　 to where the necessary vitamins were.

　　

　　    In an experiment, babies of 6 to 12 months old were placed in a　　 cafeteria (自助食堂) with a wide selection of baby food before them.　　 They were given whatever food they pointed to or appeared interested　　 in. We are told that at first they showed some unusual eating　　 patterns, but over a period of time they managed to select a well　　 balanced diet (飲食).

　　

　　     So, in selecting food, rats and babies do seem to know and act on　　 what's best for them. Clearly, there is a kind of "body wisdom" which　　 humans soon lose. Most of us do not eat as wisely as we could. Many　　 of our food preferences are culturally determined and influenced (影　　 響) by long-established habits. Some people eat fox, dog and　　 blackbirds, while we eat cows and pigs. So what people eat and how　　 much they eat seems to be greatly influenced by what is going on　　 around them.　　

　　

(1)In the experiment on rats, a fragrant flavor was added to the　　 rat's drinking water to ________.

[　　]

A. encourage rats to drink it　　 　　

B. find out what kind of flavor rats prefer　　 　　

C. test whether rats know which drink is with fragrant flavor　　 　　

D. demonstrate that vitamins are tasteless　　 　　

(2)The expression "the habit" in the first paragraph refers to　　 drinking water which __________.　　　　　　　　　　

[　　]

A. has no smell　　 B. is tasteless

C. has vitamins　　 D. is flavored　　 　　

(3)As far as their eating habits are concerned, babies and rats　　 are similar (相似) because ___________.　　　　　　

　　

[　　]

A. both have the wisdom to choose a balanced diet　　 　　

B. both prefer flavored food and drink　　 　　

C. both have the same eating patterns　　 　　

D. both develop a taste for the same kinds of flavors　　 　　

(4)In the experiment mentioned in the second paragraph, babies　　 were _________.

A. given many choices of drinks　　 　　

B. provided with various kinds of baby food　　 　　

C. placed and fed in a cafeteria　　 　　

D. trained to select a balanced diet　　 　　

(5)According to the passage, adults' (成年人) eating habits differ　　 from those of babies because ____________.　　　　

　　

[　　]

A. adults know better than babies what kinds of food are good for their health　　 　　

B. adults usually cannot resist the temptation of various delicious foods　　 　　

C. adults' eating habits are closely related to the social and cultural customs　　 　　

D. adults have more choices of food than babies in eating patterns
