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(好奇). Firstly, listen to their questions. I once visited a chlassroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary(薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “now that we’ve finished with your lists, do you have questions of your own about science?”

After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) 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, dults 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(符合逻辑的), 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(行为). 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(目标) for your disagreement.

Lastly, show; don’t 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(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.

57. According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is ________.

A. to let them see the world around B. to share the children’s curiosity

C. to explain difficult phrases about science D. to supply the children with lab equipment

58. In the last sentece of the first paragraph, the word “lists” could best be replaced by “________”.

A. any questions B. any problems

C. questions from textbooks D. any number of questions

59. According to the passage, children can answer questions in a more logical, complete and creative way if adults ________.

A. ask them to answer quickly B. wait for one or two seconds after a question

C. tell them to answer the next day D. wait at least for three seconds after a question

60. The author mentions all of the following techniques for adults to share with their children’s curiosity except that adults should ________.

A. tell their children stories instead of reciting(背诵) facts

B. offer their children chances to see things for themselves

C. be patient enough when their children answer questions

D. encourage their children to ask questions of their own

You can love them or hate them, but no matter which tourist destination you visit, chances are you’ll see someone with their head buried in a Lonely Planet guidebook.

Lonely Planet is one of the world’s largest travel guide brands, publishing more than 500 different guides in eight languages. The popular brand also produces television shows, websites and podcasts(播客)all devoted to travel.

Some people praise Lonely Planet books because they make traveling easy and affordable. They also save time and make sure you don’t miss the best things.

They also provide the reviews of hostels(旅店), hotels, restaurants and ticket information about your destination.

This can be great if you’re a nervous traveler, or if you haven’t traveled by yourself before. If you’re in a country where you don’t speak the language, sometimes there’s nothing better than getting into a taxi and opening up a guidebook. You simply point to a map that directs the taxi driver to a hostel that’s cheap and clean, with friendly staff and cold beer.

But others criticize Lonely Planet and other travel guide publishers like them. They say guidebooks take the fun and spontaneity(自发性)out of traveling, and that part of the enjoyment of travel comes from the fact that anything can happen. They also regret that if you follow a guidebook, you’ll end up doing the same thing and having the same experience as everyone else. You might end up seeing the same group of people over and over, because everyone is reading the same book and following the same route.

Another criticism of travel guides is that they have a large impact on local communities. For example, some locals devote their lives to behaving in ways that attract tourists. They pretend to live a traditional lifestyle, wear traditional clothes and live in traditional houses in order to attract the tourist dollar.

67. The Lonely Planet guidebook can bring you the following advantages EXCEPT that __________.

A. you can speak a foreign language when opening a guidebook

B. you can easily find a nice place to stay in a strange city

C. it provides lots of useful information about your destination

D. it can help you save time and money when traveling

68. People criticize the guidebook because __________.

A. it is not as useful as most travelers expect

B. tourist destinations will be crowded if everyone follows the same route

C. travelers may not get the chance to have unexpected adventures

D. local people keep modern lifestyles under its influence

69. What do we know about the Lonely Planet guidebook from the text?

A. It’s a world-famous brand only producing guidebooks for travelers.
