This is a true story between the US Air Force and parachute manufacturers in the middle of World War II. At that time, the safety performance of parachutes was not enough. Thanks to the efforts of the manufacturers, the qualified rate has been increased to 99.9%, which is almost the same. The military requires that the qualified rate of products must reach 100%. In this regard, manufacturers do not agree. They think that there is no need for improvement, and it is close to perfection to reach this level. They have repeatedly stressed that it is impossible for any product to achieve absolute 100% qualification unless there is a miracle. Think about it, the passing rate of 99.9% means that one paratrooper in every/kloc-0.000 will die because of skydiving. Later, the military changed the quality inspection method and decided to randomly select a parachute delivered by a manufacturer the week before, so that the person in charge of the manufacturer could equip himself behind him and jump off the plane himself. After this method was implemented, a miracle appeared: the unqualified rate immediately became zero.

Material (2): miracle of life: congenital deficiency, work harder.

In the women's laser sailing class competition of the London Olympic Games that ended the day before yesterday, China's Xu won the gold medal in sailing competition. She can speak fluent English, and her talent in sailing is no less than Yao's talent in basketball. She was once called "Female Yao Ming" by American media, but the growth experience behind such a tenacious athlete was not smooth sailing.

Xu's father told the media that in fact, Xu has a congenital defect-one eye can't see and hearing is defective, which makes the sailing girl have to work harder than ordinary people. She was diagnosed with a tumor in her left leg at the age of 15. Persuaded by doctors, coaches and family members, Xu finally gave up the competition and underwent surgery. Fortunately, the treatment was timely, and the doctor told her that it was a malignant tumor after the operation. If it is not removed within three months, it may become malignant, not only the whole leg will not be preserved, but even life will be in danger.

Xu practiced swimming at first. 1998, Xu and the first coach of Shanghai Sailing Team went to the swimming team of sports school to select seedlings. Because of her poor hearing, Xu is always impressed by the way she listens carefully. After being selected, she began to practice sailing under the guidance of Zhang Jing. After two years of training, Xu showed her talent for sailing. At the age of 200 1 World Championships, 14, she won the women's championship in sailing competition, and then realized her dream in major competitions.

Thanks to Xu's diligence, her grades improved year by year, and finally her dream of becoming an Olympic champion was realized.

Material (3):

This is a true story that happened in Taiwan Province province of China a few days ago. A 37-year-old woman in Kaohsiung City, Taiwan Province Province will realize her wish to be a mother through artificial conception. However, in the 39th week of her pregnancy, a sudden fire announced the unfortunate arrival. When she was rescued from the fire and sent to the nearby Affiliated Hospital of Kaohsiung Medical University, she had no breathing and heartbeat and was burned all over. However, to the surprise of the medical staff, her body is arched, and her hands tightly protect the bulging abdomen, which seems to protect the fetus in the abdomen. When the doctor opened her charred body, he was surprised to find that her stomach was still intact and white.

At this point, she has been dead for more than half an hour, but the fetus in her stomach still has a heartbeat. So she was quickly transferred to obstetrics and gynecology, and the doctor immediately gave her an external massage to help the umbilical blood flow of the fetus, and immediately performed a caesarean section. About half an hour later, the fetus was finally taken out, and it turned out to be a healthy, fat baby boy.

This is indeed a miracle. But this miracle has only one name, and that is-mother!
