问题 实验题

(4分)巴斯德是一个伟大的科学家。他在微生物研究方面比得了许多成就,其中他所设计的一个巧妙实验,曾经引起了世人的极大关注。请回答下列问题。

(l)1864年7月14日,在法国科学院的报告厅,巴斯德演示了他的实验,向世人证实了细菌不是自然发生的,而是由                    产生的。

(2)这个实验成功的关键在于(   )。

A.选择好的肉汤作为实验材料

B.实验室的良好条件

C.实验态度认真

D.设计的鹅颈瓶阻挡了细菌进入肉汤(3)巴斯德提出的牛奶保存方法被称为         消毒法。鉴于他在微生物研究方面作出的杰出贡献,后人称他为“                  ”。

答案

原来的细菌产生的  D 巴氏 微生物学之父

题目分析:巴斯德是法国微生物学家、化学家,巴斯德通过实验证明微生物只能来自微生物,而不能凭空产生,他做的一个最令人信服、然而却是十分简单的实验就是“鹅颈瓶实验”, 巴斯德将营养液(如肉汤)装入带有弯曲细管的瓶中,弯管是开口的,空气可无阻地进入瓶中,而空气中的微生物则被阻而沉积于弯管底部,不能进入瓶中,利用该实验证明细菌不是自然发生的,而是由原已存在的细菌产生的,巴斯德还发现了乳酸菌、酵母菌,提出了保存酒和牛奶的巴氏消毒法以及防止手术感染的方法,后人称他为“微生物学之父”。

点评:此题有一定的难度,巴斯德实验的内容是考试的重点内容,要好好掌握,多搜集相关的资料,了解巴斯德实验的内容以及结论等知识。

Tell a story and tell it well, and you may open wide the eyes of a child, open up lines of communication in a business, or even open people’s mind to another culture or race.

People in many places are digging up the old folk stories and the messages in them. For example, most American storytellers get their tales from a wide variety of sources, cultures, and times. They regard storytelling not only as a useful tool in child education, but also as a meaningful activity that helps adults understand themselves as well as those whose culture may be very different from their own.

“ Most local stories are based on a larger theme,” American storyteller Opalanga Pugh says, “ Cinderella(灰姑娘), or the central idea of a good child protected by her goodness, appears in various forms in almost every culture of the world.”

Working with students in schools, Pugh helps them understand their own cultures and the general messages of the stories. She works with prisoner too, helping them knowing who they are by telling stories that her listeners can write, direct, and act in their own lives. If they don’t like the story they are living, they can rewrite the story. Pugh also works to help open up lines of communication between managers and workers. “For every advance in business,” she says, “ there is a greater need for communication.” Storytelling can have a great effect on either side of the manager-worker relationship, she says.

Pugh spent several years in Nigeria, where she learned how closely storytelling was linked to the everyday life of the people there. The benefits of storytelling are found everywhere, she says.

“I learned how people used stories to spread their culture,” she says, “ What I do is to focus on the value of the stories that people can translate into their own daily world of affairs. We are all storytellers. We all have a story to tell. We tell everybody’s story.”
