I believe that it is important to be brought up with a firm belief in the good. I was fortunate in this respect. My parents not only gave me a happy home, but they had me study half a dozen foreign languages and made it possible for me to travel in other countries. This made me more tolerant and helped me to bridge many difficulties in later life.

Soon after I got married, my husband and I left our native Czechoslovakia and went to live in Shanghai, China. Here was a really international city. People of all races and beliefs lived and worked together.

In Shanghai, in 1941, when I was only twenty years old, the doctors discovered that I had diabetes. It was a terrible shock, because diabetes is incurable. But it can be controlled by insulin (胰岛素). Although this drug was not manufactured in China, there were enough stocks of imported insulin available. This enabled me to continue a normal, happy life.

Then bombs fell on Pearl Harbor and the Japanese occupied Shanghai. The import of insulin was cut off. Before long, there was not enough for the diabetics. I was on a starvation diet to keep my insulin requirements as low as possible. Many diabetics had already died, and the situation became desperate. In spite of all this, I never stopped believing that with the help of my husband’s love and care, I would survive.

I continued to teach in Chinese schools. My faith and my husband’s never-ending efforts to get the manufacture of insulin started gave me courage. In his small laboratory the production of insulin was attempted. I served as the human guinea pig（实验品）on which it was tested. I’ll never forget the day when my husband gave me the first injection of the new insulin, which had worked on rabbits. It helped! Can you imagine our happiness and relief?

I received the greatest strength from the deep love and complete understanding between my husband and me. And next to that was the kindness and help of many, many friends of many nationalities. To me, the experience of living in Shanghai during the special times was unforgettable.

After the Second World War, my husband and I sailed to the Untied States, which is also known as a melt pot. Wherever we live, I believe, with faith and love, love between families and friends from different nationalities, we can make it our cherished home.

某食品有限公司发生重大火灾事故，造成18人死亡，13人受伤，着火面积约4000m²，直接经济损失4000余万元。

经调査，认定该起事故的原因为：保鲜恒温库内的冷风机供电线路接头处过热短路，引燃墙面聚氨酸泡沫保温材料所致。起火的保鲜恒温库为单层砖混结构，吊顶和墙面均采用聚苯乙烯板，在聚苯乙烯板外表面直接喷涂聚氨酯泡沫。毗邻保鲜恒温库搭建的简易生声车向采用单层钢屋架结构，外围护采用聚苯乙烯夹芯彩钢板，吊顶为木龙骨和PVC板。车间按国家标准配置了灭火器材，无应急照明和疏散指示标志，部分疏散门采用卷帘门。起火时，南侧的安全出口被锁闭。着火当日，车间流水线南北两侧共有122人在进行装箱作业。保鲜库起火后，火势及有毒烟气迅速蔓延至整个车间。由于无人组织灭火和疏散，有12名员工在走道尽头的冰池处遇难。逃出车间的员工向领导报告了火情，10分钟后才拨打“119”报火警，有8名受伤员工在冰池处被救出。

经査，该企业消防安全管理制度不健全，单位消防安全管理人曾接受过消防安全专门培训，但由于单位生产季节性强，员工流动性大，未组织员工进行消防安全培训和疏散演练。当日值班人员对用火、用电和消防设施、器材情况进行了一次巡査后离开了车间。

根据本案例描述，该单位存在的下列违反消防安全规定的情况，应根据《机关、团体、企业、事业单位消防安全管理规定》责令当场改正的有（）。

A.违章使用明火作业或者在具有火灾、爆炸危险的场所吸烟、使用明火

B.消防设施管理、值班人员和防火巡查人员脱岗

C.常闭式防火门处于开启状态，防火卷帘下对方物品影响使用

D.消防控制室值班人员未持证上岗

E.将安全出口上锁、遮挡，或者占用、堆放物品影响使用
