New research has revealed that which song drivers listen to can influence how safe they are on the roads.Among the top ten safest songs to drive to are Come Away With Me by Norah Jones，I Don't Want to Miss a Thing by Aerosmith and Tiny Dancer by Elton John.Each of the songs has an optimum tempo(最佳节奏) for safe driving，imitating the human heartbeat at around 60 to 80 beats per minute.The Scientist by Coldplay and Justin Timberlake's Cry Me a River also appeared in the top 10.
The study，conducted at London Metropolitan University，also revealed the type of songs that cause motorists to drive dangerously.Unsurprisingly，music that is noisy increases a driver's heart rate，which can be deadly.Fast beats cause excitement that can lead people to concentrate more on the music than on the road and to speed up to match the beat of the song.Styles of music were also measured during the experiment and revealed differences between male and female drivers.Hiphop made a female driver drive far more aggressively，speeding up faster than male driver.The heavy metal music caused the fastest driving among males in the group while the dance music had the same effect among women.The male and female drivers who listened to the classical music drove the most irregularly.
The experiment involved eight people driving 500 miles each using the confused.com MotorMate app，which monitored driving behaviors through GPS technology.

×100%=12g、H元素质量=9g×
×100%=1g，其中C、H元素质量和=12g+1g=13g正好等于参加反应的A物质的质量，说明物质A中只含C、H两种元素，且C、H两元素的质量比=12g：1g=12：1；则碳氢原子个数比是1：1，因是焊接常用气体，则该气体是C2H2。
