An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding．When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives．The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS(全球定位系统) to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone．The setup of the product does not need to be hooked(钩住) up to a car’s speedometer．In fact, it is entirely portable．It will also work with newer phones and PDAs that have built-in GPS receivers．If a driver exceeds（超过） the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product．He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding．There is also a potentially future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said．“The system even has the function to record speeding violations(违背), so parents can monitor their teenage drivers.”
The product will soon go on sale in Sydney.

Little Chad was a shy, 21 young man. One day he came home and told his mother that he’d like to make a Valentine for everyone in his class. Her heart sank. She thought, “I wish he 22 do that！” because she had 23 the children when they walked home from school. Her Chad was always 24 them. They laughed and 25 on to each other. But Chad was never 26 . However, she decided she would 27 with her son. So she bought the paper and glue and crayons(蜡笔). For three weeks, night after night, Chad painstakingly made 35 valentines.
Valentine’s Day 28 , and Chad was 29 himself with excitement. He carefully put them in a bag and walked out of the door. His mother decided to bake him his favorite cookies and 30 them nice and warm with a cool glass of milk when he came home. She just knew he would be 31 and maybe that would ease(减轻) the pain a little. It hurt her to think that he wouldn’t get many valentines-maybe 32 at all.
That afternoon she had the cookies and milk on the table. When she heard the children outside, she looked out of the window. Sure enough, 33 they came, laughing and having the 34 time. And, as 35 , there was Chad at the back. He walked a little faster than usual. She 36 expected him to burst into 37 as soon as he got inside. His arms were 38 , she noticed, and when the door opened she choked back the tears.
“Mommy has some cookies and milk for you,” she said.
But he hardly heard her words, he just 39 right on by, his face aglow(满面红光), and all he could say was, “Not a one. Not a one.”
Her heart sank.
And then he added, “I didn’t forget a one, not a 40 one!”
