DFind Which Direction Is SouthDo you have a good sense of direction? If not, please take with you a compass. But if you forget to take a compass, you can still find your way.It’s never a good idea to imagine that the family member who was entrusted（委托）with the job of map-reading actually knows where the family is. You can tell by the slightly confused load on their faces that nothing on the ground seems to match the map. Never mind. The sun is shining and it’s still morning. If you don’t know the exact time, you can still find out where south is, but you’ll need to be patient.①Find a straight sick and put it in the ground in a place where you can mark its shadow.②Try to position the stick as vertically（垂直）as you can. You can check this by making a simple plumb line （铅锤线）with a piece of string and weight. You haven’t got any string? OK, use a thread from your clothes with a button tied at the end to act as a weight.③Mark the end of the shadow cast by the stick.④Wait approximately half an hour and mark the end of the shadow again.⑤Keep doing this until you have made several marks.⑥The mark nearest the stick will represent the shortest shadow, which is cast at midday, when the sun is highest in the sky and pointing to the exact south.⑦Pick a point in the distance along the line between the shortest shadow and the stick.⑧That point is south of where you are.⑨Now you can turn the map, like you did before, and find which way you should be travelling.68. To find the direction, we ought to be patient probably becauseA. it is not easy to find a proper stick B. it is not easy to position the stickC. it takes hours to make the marks D. it takes about half an hour to make the marks

Teaching aims:
Knowledge aims:
Students will know about the relation between shadow and the sun through reading the passage.
Students will master the usage of comparative degree in the reading.
Ability aim:
Students will apply the comparative degree to retell the story.
Emotional aim:
Students will be more interest in learning English.
Key and difficult point:
Key Point: Students will master the usage of comparative degree in the reading.
Difficult Point: Students will apply the comparative degree to retell the story.
Teaching procedure:
Step 1: Warming-up
1. Greetings.
2. Play a riddle--it rises up and goes down every day, what is it? and students guess it’s the sun, then lead to the story about the sun.
Step 2: Pre-reading
According to the word “sun”, students have a brainstorm about what natural phenomenon about sun they have known.
Step 3: While-reading
1. Fast reading: students read the passage fast and figure out what the tree and the duck are talking about.
2. Careful reading: students read the passage carefully and answer the question: why does the shadow get longer when the sun gets lower? And underline the words with “er”.
3. The teacher explains the words with “er” to the students.
Step4: Post-reading
1. Students work in pairs to make a role-play (one is the little duck, the other is the old tree) to make a conversation according to the passage.
2. Students work in groups to find the real reason why the shadow gets longer when the sun gets lower.
Step5: Summary and Homework
Summary: ask a student to conclude the content of the lesson and summarize with the whole class.
Homework: students tell the story to their parents.
Blackboard design:
1.Do you think repeated practice is suitable for English learning?
2.What do you think of English class activities such as role-play?
