　　马鹏飞是全国第二届道德模范，他1995年9月出生，由于父母离异，奶奶成了他唯一的亲人。

　　小鹏飞5岁时，与他相依为命的奶奶患上糖尿病合并症，（　　）双目失明，颈椎病、心脏病、末梢神经坏死病（　　）相继而至。

　　让奶奶活下去，是小鹏飞最大的希望。他说：“我特别害怕奶奶死。（　　）她不在了，我（　　）成了孤儿，没有家了！”

　　“奶奶您不要怕，今后我就是您的眼睛，给您领路！但您一定不要离开我！”小孙子那一声声稚嫩的呼唤，让奶奶心如刀绞。

　　从那时起，小鹏飞每天早上5点起床便开始忙碌起来，做早饭，收拾房间，给奶奶烧水，喂奶奶吃饭。晚上放学后，除了写作业、做饭、洗衣外，还经常带着奶奶下楼散步。在他们生活的北塔社区，经常可以看到这一老一小歪歪扭扭、蹒跚而行的背影。

　　尽管这样，小鹏飞还是最怕奶奶生病了。一次，在医院时，邻居给奶奶送来烧鸡，他喂奶奶吃，自己却不肯吃一口。他舔着手上粘着的油说：“奶奶，这鸡味儿正，是八珍的。您多吃些眼睛就能看见了。”旁边的医护人员、患者都掉下了眼泪。“从没见过这么孝顺、懂事的孩子。”

　　小鹏飞7岁时，奶奶得了肺炎高烧不退，躺在床上觉得天旋地转。到了晚上，奶奶病得喘不上来气，甚至大小便失禁。而小鹏飞十分镇静，他一点一点地用温水为奶奶擦身体，然后擦爽身粉，为奶奶换上干净的衣服，再将奶奶换下的脏衣服洗干净。

　　生活的艰辛，奶奶的病体，小鹏飞却不以为意，只要有奶奶在身边什么苦都能吃，什么罪都能受。“看着我孙子那么懂事，我都心疼得哭了。”小鹏飞是绝望中奶奶的“开心果”和精神支柱。

　　就这样，奶奶和小鹏飞幸福地生活着。

For medical students, real experience begins not in a classroom but at a teaching hospital. These doctors in training are guided. But sometimes accidents happen and the students get injured.

For example, they might stick themselves with a needle while treating patients. Such needle sticks are common. But a recent study found that medical students often fail to report them. Failing to report an injury like this can be dangerous if a patient, or a medical worker, has an infectious disease.

Researchers at Johns Hopkins University in Baltimore, Maryland, did the study, which involved a survey answered by almost 700 surgeons in training in the United States.

Almost 60% said they had suffered needle stick injuries when they were in medical school. Many said they were stuck more than once. Yet nearly half of those whose most recent incident happened in school did not report it to a health office. If they had, they would have been tested to see if they needed treatment to prevent an infection like HIV or hepatitis.

Most known cases of HIV or hepatitis are reported, but other possible infections often are not. Martin Makary, the lead author of the study, says medical students who are stuck put themselves and others in danger from infectious diseases.

Doctor Makary said, "A needle that goes through the skin needs to be as sharp as possible.” Doctors in training may have to do hundreds of stitches (缝线) in some cases to close the skin after an operation.

Doctor Makary said, “I support using blunt tip needles which are considered safer. This needle is still sharp enough to go through body tissue, but it does have a blunt tip, so that if it accidentally goes into my finger, it's much less likely to hurt me."

How common are needle sticks among health care workers? An estimated 600,000 to 800,000 of these and similar injuries are reported each year in the United States. But Doctor Makary says the real number may be much higher.

The study advises doctors to protect their hands by wearing two sets of gloves. It also urges hospitals to establish a special telephone number for medical workers and students to call if they are injured. The idea is for hospitals to send a clear message that there is no reason not to report this kind of accident.
