小儿腹内脏器疝入脐带基部称为()

A.脐尿管未闭

B.卵黄管未闭

C.脐膨出

D.脐炎

E.腹裂畸形

答案

参考答案:C

解析:小儿腹内脏器疝入脐带基部,称为脐膨出,是一种先天性腹壁发育不全,在脐带周围发生缺陷,使腹内脏器脱出体外。脐尿管未闭、卵黄管未闭和脐炎均不出现脐膨出,腹裂畸形虽有内脏脱出,但脐孔是正常的,缺损位于腹中线旁,内脏是从腹侧壁脱出。

If you want to become a better reader, here are four important points to remember about rate or speed(速度)of reading:

First, knowing why you are reading and what you are reading to find out will often help you to know whether to read rapidly or slowly.

Second, some things should be read slowly. Examples are directions for making or doing something; arithmetic(算术)problems, science and history books. They are full of important information. You must read such things slowly to remember each important step and understand each idea.

Third, some things should be read rapidly. Examples are simple stories for enjoyment, news, letters from friends, items or bits of news from local or hometown paper, telling what is happening to friends and neighbors.

Fourth, in some of your readings, you must change your speed from fast to slow, and slow to fast, as you read. You’ll need to read certain pages rapidly and then slow down and do more careful reading when you come to important ideas which should be remembered.
