A device that stops drivers from falling asleep at the 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 piloterror 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.
(1)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
(2)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.
(3)We can learn from the text that the driver needs to stop for a break when his response time ______.
[ ]
A．about 400 milliseconds
B．below 500 milliseconds
C．over 500 milliseconds
D．about 4 minutes
(4)When the driver gets sleepy while driving, Driver Alert _____.

Early in the development of agriculture men discovered how to make alcoholic (酒精的) drinks from grapes and com. The ancient Egyptians drank both wine and beer, and the Greeks carried on a lively trade in wine throughout the Mediter ranean.The vines of grapes are all of a single species (物种). Vitis vinifera, although there are hundreds of varieties adapted to different soils and climates.
Wine is the fermented (发酵的) juice of fresh grapes. The juice of the wine grape contains sugar, and growths of yeast (酵母) form on the outside of the grape skins. In wine making, the grapes are crushed in a wine press and the yeast converts (改变)the sugar to alcohol, when there is no air present, by a process(处理)called fermentation. Red wine is made from dark grapes, and white wine from white grapes or from dark grapes whose skins have been removed from the wine press at an early stage. The most famous wine-growing countries are France, Germany and Italy. Wine was made in England in the Middle Ages, but the climate is not really suitable for grapevines. Wines must be drunk quickly once they are opened, otherwise bacteria (细菌) will use the air to convert the alcohol to vinegar. The bacteria are killed by a higher alcohol content than is found in wine and that is why sherry and port, the specialties (特制品) of Spain and Portugal, are fortified (加度) by the addition of spirits to make them last longer.
Beer is made from barley (大麦) grains which is fermented with yeast to produce alcohol; hops are added for flavour (特别的味道) .Ale, the most common drink in England in the Middle Ages, was also made from barley, but without hops, the ale of today is merely a type of beer. In Japan beer is made from rice.
Spirits have a higher alcoholic content than beer and wine and are made by distillation (蒸馏) from a base or grain or some other vegetables. Gin and vodka can be distilled from avariety of ingredients (原料), including potatoes; Scotch whisky is obtained from a base of fermented barley, and brandy form the distillation of wine. Cider is made from apples. South American Indians make alcoholic drinks from cactus leaves and the shoots of certain palm trees.
1．The “press” ( Sentence 3, Para. 2) is most probably ________.
[ ]
A．a machine for making wine
B．a container for changing the sugar to alcohol
C．a device for crushing grapes
D．a process called fermentation
2．From the second paragraph, we learn that ________.
[ ]
A．red wine and white wine are made from grapes with skins
B．wine was first made in England in the Middle Ages
C．wines must be drunk quickly once they were opened because they are made by fermentation
D．wines can last longer by adding strong alcohol because bacteria are killed
3．According to the author, spirits ________.
[ ]
A．are made by fermentation
B．are all made from grains, potatoes and apples
C．are strong alcoholic drinks
D．are getting popular in South America.
4．Which of the following statements is true?
[ ]
A．All vines of grapes belong to one species.
B．The most famous wine-growing countries are France, Germany and England.
C．Ale is the most common drink in England today.
D．All kinds of whisky is made from barley.
5．The best title for the passage would be“________”.
[ ]
A．Wine, Beer and Spirits
B．Drinks from Fruits and Grains
C．The Development of Drinks
D．The History of Drinks

科目：高中英语 来源： 题型：阅读理解
A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what’s happening in their brains.
When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons(神经元) are responsible for this processing.
The fMRI (functional Magnetic Resonance Imaging功能性磁共振造影) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.
Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize which parts of the brain receive more oxygen- rich blood--and therefore, which parts are working to process information.
An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.
The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.
In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly, related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.
51. What is responsible for processing the information sent by your eyes?
A A small region of the brain.
B The central part of the brain.
C Neurons in the brain.
D Oxygen-rich blood.
52. Which of the following statements is NOT meant by the writer?
A Cells in your brain are called neurons.
B The more oxygen a neuron consumes, the more blood it needs.
C fMRI helps scientists to discover which parts of the brain process information.
D fMRI helps scientists to discover how the brain develops intelligently.
53. "Highlighting the areas of the brain at work" means
A "marking the parts of the brain that are processing information"
B "giving light to the parts of the brain that are processing information"
C "putting the parts of the brain to work"
D "stopping the parts of the brain from working"
54. What did the researchers experiment on?
A Animals, objects, and fruits.
B Two volunteers.
C fMRI machines.
D Thousands of pictures.
55.What is the best title for the passage?
A Mind-reading Machine
B A Technological Dream
C Device that can Help You Calculate
