Jodie’s Daddy Is a Garbageman(垃圾清理工)

Mr Swales wanted to find out what his students’ parents did. He had just called Jodie when some girls burst out laughing. Shirley shouted, “Jodie’s daddy is a garbageman!”

Everybody in the class laughed out loud, except Jodie. She felt her face turn red.

“Silence!” Mr Swales said, “Being a garbagemen is a difficult and useful job. We should all be grateful to Jodie’s father.”

Jodie’s father came to walk her home from school as usual, but she didn’t run up to him the way she always did. When they got back home, Jodie went to her room and cried for a long time.

Her father came into her room, “What happened, Jodie? Why are you so sad?”

Jodie told her father what had happened and looked at him. He didn’t seem angry or hurt. “Well,” he said, “they are right. Being a garbageman is a dirty job. Tomorrow’s Saturday. Come to work with me, Jodie.”

The place really smelt too bad. Jodie wrinkled her nose. “Don’t worry, kid. In five minute you won’t smell a thing.” said her father.

Everybody there was working hard, and they seemed to have a good time. Jodie’s father handed her a pair of gloves and told her to get the little plastic bags and throw them into the truck.

It was fun, but also hard work. Jodie’s arms soon got tired. At last, no more garbage was left and Jodie felt very happy.

“Garbage is disgusting, but when we clear it away, everything’s nice and clean. You can make yourself happy only by making other happy. That’s why I like being a garbageman so much.”

Jodie gave her dirty, smelly garbageman daddy a big kiss(吻). She said, “When I grow up, I will be a garbage-girl!”

Now whenever someone asks Jodie what her daddy does, she says, “He’s a garbageman! Everybody makes garbage, but my daddy takes it away!”

有这样一种假说：冬眠是一种高度发达的机能。冬眠的哺乳动物虽然与人类一样都是温血动物，但是它们在更宽范围的调节性上获得了进化，例如在体温调节上，就要比非冬眠动物强。传统观点认为，哺乳动物冬眠的奥秘在于心脏。无论冬眠动物，还是非冬眠动物，甚至人类，其心脏工作的原理是相同的。当钙离子流进心脏的细胞时，就引起心脏收缩；当钙离子随即排出细胞时，心脏又开始舒张。但是随着温度的降低，非冬眠动物的心脏活动细胞排除钙离子的能力明显降低，从而使心脏的舒张越来越困难，最后导致死亡；而此时冬眠动物的心脏细胞则完全与此相反。因此心脏细胞调节钙离子浓度的机制，是冬眠时心脏正常活动的关键所在。后来的研究证实，心脏细胞的这种变化______冬眠的根本原因，科学家们推测冬眠最终是由动物体内的遗传基因控制的。然而，人们却一直没有发现这种遗传基因。直到最近，日本科学家发现，在美洲松鼠等冬眠动物的血液中存在一种特殊的蛋白质HP。HP只能在冬眠动物身上找到，并与冬眠同步出现。这表明，HP在冬眠中具有重要的作用。那么，在人类身上也能找到类似冬眠的现象吗人类也可能冬眠吗答案是肯定的。人在睡眠时也有体温降低、心跳放慢的现象，这在性质上与冬眠相似。而身体硕大的熊的冬眠，为实现人类的冬眠提供了可能。如果以HP为线索，也许能重新认识熊的冬眠。一旦控制熊冬眠的遗传基因得以破译，人的冬眠就不是不可能了。这样，人类就能把自身的代谢控制到最低极限，从而有利于癌症等疾病的长期治疗、未来的宇宙旅行等。

文中认为“HP在冬眠中具有重要的作用”，下列不能作为这一观点的根据的一项是（）

A．科学家们推测冬眠最终是由冬眠动物体内的遗传基因控制的

B．HP是在冬眠动物的血液中新发现的一种特殊的蛋白质

C．HP不能在非冬眠动物体内找到，而它的出现周期又跟冬眠动物的冬眠周期相同

D．在发现HP之前，人们一直没有发现动物体内控制冬眠的遗传基因

某在建矿井，设计生产规模较大。该矿井附近有开采多年的小煤矿，且开采情况不清。在矿井施工转入二期、三期工程(即井底车场、巷道和采区工程)开拓期间，由于工期安排较紧，建设单位引入了多个施工队伍同时施工。在某工作面施工过程中，施工人员 

汇报该工作面渗水增大，局部有顶板片落的情况，但没引起有关人员的重视，未进行探水工作。隔天，工作面放炮后发生了重大突水事故，并造成矿井淹井。

1．针对该矿井附近有小煤矿的情况，建设单位应做好哪些工作? 2．根据该矿井附近有已采矿井的情况，施工单位应要求建设单位提供哪些必要条件?应考虑到哪些风险?针对这些风险，施工中应遵循哪些原则? 3．巷道掘进工作面突水前有什么征兆? 4．巷道掘进工作面探水应采取哪些安全措施? 5．针对本案例，简要说明建设单位在安全管理方面的主要工作内容。
