　　[2015·甘肃兰州双基考]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 lead­footed_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 (车队)．

　　The product,

　　called Speed Alert,

　　links real­time location

　　data and speed obtained with the help of GPS 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 up to a car's speedometer (速度计).

　　In fact,

　　it is

　　entirely portable. It will also work with newer phones and

　　PDAs that have built­in 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

　　“an

　　intelligent speed alert”.

　　Other research, according to Paine,

　　shows that 40 percent of all traffic deaths involve speeding.

　　There is also a potentially controversial 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 capability to record speeding violations, so parents can

　　monitor their teenage drivers.”

　　[2015·河北邢台摸底考]When Sabrina Vega was 5 years old, a friend invited her

　　to a party held at a gym where Sabrina discovered that she

　　loved doing gymnastics.

　　A few nights after the party, Sabrina had a dream. She

　　told her mother, Jahira, about the dream. Jahira said, “Sabrina said that in her dream she went to the Olympics. She describedeverything at this international competition. At first I did not take her story seriously.”

　　But Sabrina kept talking about her dream. She told it to

　　her father, David. So Jahira and David decided to pay for Sabrina to learn gymnastics. So Sabrina started to train at a special and competitive gym. Though only 7 years old, she was already training to compete at a high level. The years passed quickly. Sabrina got better and better. By the time she was 12 years old, Sabrina was training so many hours each day that she did not have time to do things that many other Americans of the same age did.

　　When Sabrina was 13, she had a chance to compete in a

　　national gymnastics event. If she did well, the event would

　　give her the chance to join the national team－the team that

　　trains for the Olympics.

　　But the family was out of money. Jahira had to tell

　　Sabrina that she could not go.

　　Jahira said, “Tears came to her

　　eyes, and she said,

　　‘I understand.’”

　　A week or two later, a rich family came to visit Sabrina's

　　gym unexpectedly. They watched Sabrina train. Then they

　　asked to talk to her mother. The rich family offered Jahira all

　　the money they needed!

　　Eventually，

　　Sabrina Vega competed at the 2017 Olympic

　　trials. She finished 10th in the all rounds.
