As they were working, some visitors stopped by to watch. A man asked what they were doing. "We plan to dig a hole all the way through the earth," one of the boys replied excitedly.‎ The visitors began to laugh and told them not to do that because they thought that digging a hole all the way through the earth was impossible. Then one of them picked up a jar(罐子) filled with stones of ‎ different sizes and shapes. He showed it to the laughing visitors and said proudly, "Even if we can't dig all the way through the earth, look at what we found along the way!"‎ Their goal(目标) was far too difficult to come true, but it did cause them to dig. And that is what a goal is for—to cause us to move in the direction we have chosen.‎ But not every goal will be fully achieved. Not every job will end successfully. Not every hope will come to pass. Not every love will last. Not every hard work will be completed. Not every dream will be realized. But when you have a goal, perhaps you can say, "Yes, but look at what I found along the way! Look at the wonderful things which have come into my life because I tried to do something!"‎ It is in the digging that life is getting more colorful. And I believe it is joy in the journey that is truly important to us.‎ ‎1.What were the two brothers doing at the beginning of the story?‎ A．Looking for stones. ‎ B．Playing with the visitors. ‎ C．Digging a hole in the earthe。‎ D． Showing their stones to the visitors.‎ ‎2.What did the visitors think of the two brothers' plan?‎ A． Difficult. B．Exciting. C．Interesting. D．Dangerous.‎ ‎3.What does the underlined word "it" in the third paragraph refer to?‎ A． The jar. B．The earth. C．The hole. D．The goal.‎ ‎4.What does the fourth paragraph tell us?‎ A．Change your goal when you can't achieve it.‎ B．Work hard, or your job will not end successfully.‎ C．Try your best and you will enjoy wonderful things.‎ D． Hold on to your dream and you will realize it one day.‎ ‎5.What is the best title for the passage?‎ A．Joy in the Journey B．Love in Our Life C．Stones in the Jar D．Friendship in the Digging B Ever wonder why you can go over a book again and still be lost when tested on what you read? It may be because you haven't practiced remembering.‎ Remembering is a useful way to help us learn. Some of us remember best by listening; others by re-reading; and others learn best by using pictures and diagrams (图表). Schools try many of these different ways to help students "download" new information.‎ But a recent study from Purdue University US, says that successful learning means being able to recall information at any moment.‎ ‎"We think that learning is not about studying or getting knowledge in memory," said Jeffey Karpicke, the lead researcher, "Learning is about retrieving(寻回,检索). So it is important to make retrieval practice an important part of the learning process."‎ The research studied two groups of students. Both groups learned something from a text. One group made diagrams about the text. This method is called concept mapping. The other group put the test away after learning it and tried recalling the concepts from memory.‎ Then, both groups were tested on the information they had learned. Both groups scored(得分) well at recalling the learned information. However, when they were asked to return one week later, the group who made diagrams was better than the group who did not use concept mapping. So by drawing concept maps, we are able to recall information far better, which will help us to study.‎ Our mind, just like our body, has to practice activities to become good at them.‎ ‎6.Which of the following ways of remembering is NOT mentioned in Paragraph 2?‎ A．Listening. B．Speaking.‎ B． Re-reading. D．Using pictures and diagrams.‎ ‎7.According to Jeffey Karpicke, learning is about ._____________‎ A．studying knowledge from memory B．getting knowledge from memory C．practicing drawing photos and maps D． practicing recalling knowledge ‎8.What does the word "concept mapping" in Paragraph 5 mean in Chinese?‎ A． 规划图 B．心电图 C．线路图 D．概念图 ‎9.When both groups were tested on the information after one week,._______________‎ A．they both scored well B．neither of the groups scored well C．the group using concept mapping scored better D． the group that didn't use concept mapping scored better ‎10.What can be learnt from the passage?‎ A．Concept mapping is the only way to learn.‎ B．How to get knowledge by concept mapping.‎ C．Our minds need to practice to remember things.‎ D．It's impossible to remember everything we've learned.‎ C Name: Hans Mestrum Date of birth: 28, January Nationality: Dutch Sex: male Martal status (婚姻状况): Married (2 children)‎ Address: van Hornstraat 19 5282 NA Boxtel Telephone: +31 (0)411-683941 (home) +31 (0)6-38898211 (mobile)‎ Email: hmestrum@solcon.nl (private)‎ Weblogs: ‎ ‎● Hans on Experience: http://www.hansonexperience.com ‎● Screencasting and Video Podcasting: http://www.hansonexperience.com/screencasting Education:‎ ‎● Teacher's Graduate for Highschool in Dutch language ‎● Teacher's Graduate for Secondary School ‎● Highschool Work history:‎ Aug. 2019‎ ‎● recent Orion College Breda: Advisor/teacher ‎● coaching of 15 Highschool students in a new educational setting ‎2019-July 2019 ‎ Tulip Computers N.V.: Senior Strategic Business Developer ‎● special interest in new media(媒体) and social software(软件).‎ ‎● active in new media ‎● speaker on workshops, conferences, debates and lectures ‎● enable of new media and social software ‎2019-April 2019 ‎ NewLevel.
