阅读下面的文言文选段,完成1~5小题。

  古之学者必有师。师者,所以传道受业解惑也。人非生而知之者,孰能无惑?惑而不从师,其为惑也,终不解矣。生乎吾前,其闻道也固先乎吾,吾从而师之;生乎吾后,其闻道也亦先乎吾,吾从而师之。吾师道也,夫庸知其年之先后生于吾乎?是故无贵无贱,无长无少,道之所存,师之所存也。

  嗟乎!师道之不传也久矣!欲人之无惑也难矣!古之圣人,其出人也远矣,犹且从师而问焉;今之众人,其下圣人也亦远矣,而耻学于师。是故圣益圣,愚益愚。圣人之所以为圣,愚人之所以为愚,其皆出于此乎?爱其子,择师而教之;于其身也,则耻师焉,惑矣。彼童子之师,授之书而习其句读者,非吾所谓传其道解其惑者也。句读之不知,惑之不解,或师焉,或不焉,小学而大遗,吾未见其明也。巫医乐师百工之人,不耻相师。士大夫之族,曰师曰弟子云者,则群聚而笑之。问之,则曰,“彼与彼年相若也,道相似也,位卑则足羞,官盛则近谀。”呜呼!师道之不复,可知矣。巫医乐师百工之人,君子不齿,今其智乃反不能及,其可怪也欤!

单项选择题

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me "textbook questions" about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, "Now that we’re finished with your lists, do you have questions of your own about science"

In which of the following paragraph(s) does the author tell us what to say to encourage children in a science discussion
A. The second and third.
B. The fourth and fifth.
C. The fifth and sixth.
D. The seventh.

After a long pause, a boy raised his hand, "Have you ever seen a grasshopper eat When I try eating leaves like that, I get a stomachache. Why"
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their "wait time" to three seconds or more, children give more logical, complete and creative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with "That’s right" or "Very good". These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying "That’s interesting" or "I’d never thought of it that way before", or coming up with more questions or ideas.
Never push a child to "Think". It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.
Lastly, show; don’t just tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass, and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates, set a pot of water to boil and let them watch the water level drop.
