问题 单项选择题

溶血性黄疸的特点是()

A.血中结合胆红素含量增高

B.血中胆素原剧减

C.尿中胆红素增加

D.未结合胆红素浓度增高

E.粪便颜色变浅

答案

参考答案:D

解析:溶血性黄疸时,血中游离胆红素明显增高,尿胆素原和粪胆素原增加。由于游离胆红素与血浆清蛋白结合,不能通过肾小球而随尿排出,所以尿胆红素呈阴性。

单项选择题

阅读下面短文,回答下面题。
我就职的第一家公司是一家美资公司。员工餐厅位于办公楼的三楼。某天晚上我加班到近十点钟,离开时发现整个办公楼里只剩下我,但走廊的灯全都亮着,多浪费呀,我心里想着,不仅关了一楼走廊的灯,还爬上二楼三楼,把灯全关了。
第二天早会上,外籍经理说:“昨天是哪位员工最后一个离开的办公楼感谢他为公司节约考虑熄灭了所有的灯。但是,从安全的角度,我们要让所有走廊通宵明亮,因为夜班员工可能要到三楼进餐,黑暗的楼道容易摔跤。我们付出的是有限的电费,但避免了潜在的伤害。”
我就职的第二家公司是一家英资公司。负责安全的经理给新员工的安全培训中说:“一旦发生火灾,公司不需要你们去救火或者去抢救公司财产。员工是公司最宝贵的财产,人的生命最宝贵。你们要做的是保证自身的安全,迅速撤离,在确保自身没有危险的情况下,拨打119火警电话,请专业人员来灭火。”
到底什么是最重要的
我不禁联想到20世纪80年代讨论的大学生张华为救落入粪池的老大爷而牺牲,以及前些天报道的中学生为抢救落水同学, 自己再也没有上来的事情。
我想说,我们应该从小就教育下一代,好好爱惜生命,不要教育,或诱导他们不管自身条件,不计客观效果,盲目舍己救人。对生命的珍视和爱护程度体现着这个国家的文明程度。让他们在救人时,能够客观权衡。西方国家从来没有过这样舍己救人舍生抢救国家财产的教育和舆论导向,他们受到的都是生命至上的人本主义教育。但我在国外绝少看到危难或交通事故时有人袖手旁观,遇到紧急情况总有很多自发自觉的救助者,从他们身上我看到的是人性的光辉。但从我们这些懵懵懂懂跳下河去再也没有上来的孩子身上,我感觉到的只是痛惜和痛心。
真正做到以人为本,我们还有很长的路要走,这是我们这一代人,甚至几代人的责任。
(一冰《经历“以人为本”》)

     Years ago, if a teenager had some problems in his life, he might write them in his diary. Now he might get

on the Internet and write them in his blog (博客). In many ways, a diary and a blog are almost the same. Then,

what makes a blog different from a diary?

     The biggest difference is that a blog is much more public than a diary. Anyone can read what you write in

your blog. Usually, a teenager likes hiding his diary book and treats it as secret. If you are not satisfied with a

friend and write something bad about him in your diary, he will never know it. However, if you do this on the

Internet,that friend may read your blog and get angry. So we have to be careful of what we write.

     A blog has good points, of course. People choose to write in blogs, they know that their friends will read

what they write. If you feel sad one day and write in your diary, no one will know about it. If you write the

same words in your blog, your friends may quickly writer back to comfort you and offer their help. Blogs

help people know what their friends are doing.

     Though it's a good way to write blogs about everday life, I still prefer my old diary.
