June 5, 2014 Dear Mr. Blake,

It was very enjoyable to speak with you about the assistant account manager position at the Smith & Smith Co. Ltd. The job seems to be a very good match for my skills and interests. In addition to my keen interest, I will bring to the position strong writing skills and the ability to encourage others to work well with the department. My art background will help me to work with artists on staff and provide me with an understanding of the artistic aspects of our work.

I understand your need for office work support. My basic trainings and organizational skills will help to free you to deal with larger issues. I neglected to mention during my interview that I had worked for two summers as a part-time office worker. This experience helped me to develop my skills as an office secretary.

I appreciate the time you took to interview me. I am very interested in working for you and look forward to hearing from you about this position.

Best regards,

John Smith

Pushbike Danger

Low speed bicycle crashes can badly injure -- or even kill -- children if they fall onto the ends of the handlebars (车把). So a team of engineers is redesigning it to make it safer.

Kristy Arbogast, a bioengineer at the Children's Hospital of Philadelphia in Pennsylvania, began the project with her colleagues. The cases they reviewed about serious abdominal (腹部的) injuries in children in the past 30 years showed that more than a third were caused by bicycle accidents, "The task was to identify how the injuries occurred and come up with some countermeasures," she says.

By interviewing the children and their parents, Arbogast and her team were able to reconstruct many of the accidents and identified a common cause for serious injuries. They discovered that most cases occur when children hit an obstacle at slow speed, causing them to topple (摇摆) over. To maintain their balance the children turn the handlebars through 90 degrees -- but their momentum (冲力) forces them into the end of the handlebars. The bike then falls over and the other end of the handlebars hits the ground, pushing it into their abdomen (腹部).

The solution the group came up with is a handgrip (握柄) fitted with a spring and damping (减速) system. The spring absorbs up to 50 per cent of the forces transmitted (传递) through the handlebars in an impact. The group hopes to commercialize the device, which should add only a few dollars to the cost of a bike. "But our task has been one of education because up until now, bicycle manufacturers were unaware of the problem," says Arbogast.

The engineers are trying to improve the handlebars because

A．they are not beautiful.

B．they may kill children.

C．they are likely to crash.

D．they affect the speed of the bike.
