Warford is an optometrist (验光师) in Florida. He has seen an increase in “computer vision syndrome(电脑视力综合症)”in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried，” he says.
Dr. Watford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or whatever taken away，” he explains.
He says another part of the problem is that people blink(眨眼)less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And that can result in the front part of the eye drying and not staying protected like normal.”
Eye doctors offer suggestions like the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.
Other suggestions include using good lighting and spending less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, for instance, says, “While it is possible to develop fatigue looking at screens for a long time, there’s certainly no proof that it actually causes any damage to the eyes.”
1.Which of the following is true according to the passage?
A. Dr. Warford thinks using computers causes nearsightedness.
B. People keep their eyes protected against drying by blinking normally.
C. The 20/20/20 rule doesn’t apply to all the devices you are using.
D. Children under two can watch TV for less than two hours a day.
2.The syndrome in children is more likely serious than in adults because ________.
A. adults are cleverer than children
B. adults ignore taking care of children
C. children always overlook early warning signs
D. children always forget their parents’ words
3.What does the underlined word “fatigue” mean in the last paragraph?
A. interest. B. ability. C. difficulty. D. tiredness.
4.What can be the best title for the passage?
A. Looking at Screen: Two Hours or More
B. How Can Children Use Their Eyes Properly
C. Using Digital Devices: Advantages and Disadvantages
D. How Much Screen Time Is Proper for Children

Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobilizer (发动机防盗系统), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again.
The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle’s engine management system and prevent the engine being restarted.
In the UK, a set of technical fixes is already making life harder for car thieves. “The pattern of vehicle crime has changed,” says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools, but only if the car is more than ten years old. Modern cars are far tougher to steal, as their engine management computer won’t allow them to start unless they receive a unique ID code beamed out by the ignition key (汽车等的点火开关).
In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner’s keys .And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle’s movements via the car’s GPS unit.
1.What’s the function of the remote immobilizer fitted to a car?
A. To allow the car to lock automatically when stolen
B. To prevent the car thief from restarting it once it stops
C. To help the police make a surprise attack on the car thief
D. To prevent car theft by sending a radio signal to the car owner
2.By saying “The pattern of vehicle crime has changed” (Lines1-2,Para.3) Martyn Randall suggests that _____.
A. Self-prepared tools are no longer enough for car theft
B. the thief has to make use of computer technology
C. it takes a longer time for the car thief to do the stealing
D. the thief has lost interest in stealing cars over 10 years old
3.What is essential in making a modern car tougher to steal?
A. A GPS satellite positioning receiver
B. A unique ID card
C. A special cellphone
D. A code ignition key
4.Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?
A. To give the driver time to contact the operation centre
B. To allow for possible errors in the GPS system
C. To keep police informed of the car’s movements
D. To leave time for the operations centre to give an alarm

The latest study by the University of Florida has found that eating from smaller, less beautiful, and even paper plates will help prevent overeating. Eating with a fork instead of a spoon can help you lose weight, the researchers say. Much to their surprise, they find that putting mirrors in the dining room will also help reduce weight.
The researchers asked 185 college students to choose a chocolate cake or a fruit salad, and evaluated the taste. Those who ate in a room with a mirror scored the taste of junk food much lower than those in a room without a mirror. But the taste of fruit salad remained the same in any case.
Lead scientist, Dr. Ata Jami, says that a glance in the mirror tells people more than just about their physical appearance. It enables them to view themselves objectively and helps them to judge themselves and their behavior in the same way that they judge other people.
The mirrors were found to push people to compare and match their own behavior with accepted social standards. The researchers believe it proves that people don’t want to look in the mirror when they feel they are following the social standards. When they look in the mirror with mouths full of junk food, feelings of discomfort and failure can be increased. Therefore, the presence of the mirror lowers the taste of unhealthy food.
However, researchers say this is only the case if people select the food they are eating, because they are responsible for that choice. The researchers suggest that mirrors be placed in dining rooms and other eating spaces, so that people will start eating more healthily.
1.Researchers are amazed to find that ______.
A. paper plates make food look nicer
B. people using a fork will eat more
C. mirrors can help people lose weight
D. people will eat more in front of a mirror
2.What can be inferred from the study?
A. Some teenagers got involved in it.
B. People were required to eat with a spoon.
C. People preferred a chocolate cake to a fruit salad.
D. The mirror may not affect the taste of healthy food.
3.According to Dr. Ata Jami, the mirror ______.
A. makes people judge others correctly
B. makes people well judge themselves
C. is a necessary part of people’s daily life
D. can only show the appearance of a person
4.How does the mirror affect the taste of junk food?
A. By making people hungry.
B. By showing the social standards.
C. By attracting people to healthy food.
D. By causing a feeling of discomfort.
