                                               Three Things to Do Before You Are 18

    Are you bored with your daily life? Here are some things you should try before you are 18, because

after that it's too late.

    Learn to swim

    Seriously, this is so important that it can save your life. If you can't swim well, you won't be able to

do water sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you.

Make sure you do it.

    Try at least one kind of team sports 

    Being a good team player is an important skill in life. You can't just think of yourself, but have to work

well with other people. Other advantages of team sports like basketball, football and baseball are that they

keep you fit and healthy, and they are also great fun. Teams usually have a good social life too-you'll go

to lots of parties and make many friends.

    Collect something

    One of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you

could collect things that make you remember what you have done, like cinema tickets for films you have

seen or emails from friends. The best way to collect is to have a special album to put your collection in and

to write what each thing means to you. That way you won't forget.

甲图是某人在饭前、饭后血糖含量变化曲线,乙图表示人体内血糖浓度调节的反射弧示意图,请分析回答:

(1)甲图中饭后l小时cd段血糖含量大幅上升是由于食物中的         被消化后的产物进入血液造成的。

(2)人体内有对血糖敏感的感受器,当人体的血糖浓度高于正常水平时(如饭后),对血糖敏感的感受器会产生兴奋,通过图乙中的[  ]        传至神经中枢,在相应神经中枢的作用下,神经冲动由②传至效应器——胰岛,使其加速分泌胰岛素,使血糖浓度         ,恢复正常水平。

(3)像这样,人体通过神经系统对刺激所发生的有规律的反应叫做        。某些激素(如甲状腺激素)也能影响胰岛素的分泌,所以说,正常人的血糖浓度能保持相对稳定是                 协调作用的结果,使人体成为一个统一的整体。

某市政工程基础采用明挖基坑施工,基坑挖深为5.5m,地下水在地面以下1.5m,坑底黏土下存在承压水层。坑壁采用网喷混凝土加固。基坑附近有高层建筑物及大量地下管线。设计要求每层开挖1.5m,即进行挂网喷射混凝土加固。由于在市区,现场场地狭小,项目经理决定把钢材堆放在基坑坑顶附近;为便于出土,把开挖的弃土先堆放在基坑北侧坑顶,然后再装入自卸汽车运出。由于工期紧张,施工单位把每层开挖深度增大为3.0m,以加快基坑挖土及加固施工的进度。在开挖第二层土时,基坑变形量显著增大,变形发展速率越来越快。随着开挖深度的增加,坑顶地表出现许多平行基坑裂缝。但施工单位对此没有在意,继续按原方案开挖。当基坑施工至5m深时,基坑出现了明显的坍塌征兆。项目经理决定对基坑进行加固处理,组织人员在坑内抢险,但已经为时过晚,基坑坍塌造成了多人死亡的重大事故,并造成了巨大的经济损失。

本工程基坑侧壁安全等级应属于()。

A.一级

B.二级

C.三级

D.四级
