問題二：上述問題中，甲、乙的平均數(shù)、中位數(shù)、眾數(shù)相同，但二者的射擊成績存在差異，那么，如何度量這種差異呢？我們可以利用極差進行度量。根據(jù)上述數(shù)據(jù)計算得：甲的極差=10-4=6 乙的極差=9-5=4極差在一定程度上刻畫了數(shù)據(jù)的離散程度。由極差發(fā)現(xiàn)甲的成績波動范圍比乙的大。但由于極差只使用了數(shù)據(jù)中最大、最小兩個值的信息，所含的信息量很少。也就是說，極差度量出的差異誤差較大。問題三：你還能想出其他刻畫數(shù)據(jù)離散程度的辦法嗎？我們知道，如果射擊的成績很穩(wěn)定，那么大多數(shù)的射擊成績離平均成績不會太遠；相反，如果射擊的成績波動幅度很大，那么大多數(shù)的射擊成績離平均成績會比較遠。因此，我們可以通過這兩組射擊成績與它們的平均成績的“平均距離”來度量成績的波動幅度。

可以通過下面的步驟計算一組n個數(shù)據(jù)的第p百分位數(shù)：第一步：按從小到大排列原始數(shù)據(jù)；第二步：計算i=n×p%；第三步：若i不是整數(shù)，而大于i的比鄰整數(shù)位j，則第p百分位數(shù)為第j項數(shù)據(jù)；若i是整數(shù)，則第p百分位數(shù)為第i項與第i+1項的平均數(shù)。我們在初中學過的中位數(shù)，相當于是第50百分位數(shù)。在實際應用中，除了中位數(shù)外，常用的分位數(shù)還有第25百分位數(shù)，第75百分位數(shù)。這三個分位數(shù)把一組由小到大排列后的數(shù)據(jù)分成四等份，因此稱為四分位數(shù)。其中第25百分位數(shù)也稱為第一四分位數(shù)或下四分位數(shù)等，第75百分位數(shù)也稱為第三四分位數(shù)或上四分位數(shù)等。另外，像第1百分位數(shù)，第5百分位數(shù)，第95百分位數(shù)，和第99百分位數(shù)在統(tǒng)計中也經(jīng)常被使用。例2、根據(jù)下列樣本數(shù)據(jù)，估計樹人中學高一年級女生第25，50，75百分位數(shù)。

Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

1. 這個寓言是一個關于一位國王古寓言。 The fable is an old fable about a king.2.作者用這個故事讓讀者對于社區(qū)的問題負有個人責任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 這個故事十分成功的實現(xiàn)了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3. Does the writer give his or her opinion about the character or their actions ?4. Is the review well-organised ? 5. Does the writer use the -ing form as the adverbial correctly in the writing ?6. Are there any grammar, spelling, or punctuation errors ?Step 9 HomeworkPut up your revised draft in the classroom or read it to your class.
