答案
1、 擴散??比熱容
2、 比熱容大 、降低、碗中的水達到沸點后無法繼續吸熱
3、 做功?? ????熱傳遞??????比熱容
4、 比熱容
5、 ?4.2×103????大
6、 【解析】試題分析：由得：，然而在一標準大氣壓下，水的沸點為100℃，所以30℃的水只能升高到100℃，升高70℃。
考點：熱量計算
7、 C 8、B 9、B 10、B 11、A 12、A 13、C 14、A 15、D
16、（1）相同時間液體吸收的熱量相同??（2）①水? ②水??（每??空2分）
17、（1）秒表???（2）4.2×103???增大??
18、解：C=??冰增加的內能就是吸收的熱量為800J。

Unit 5 Overcoming Obstacles
Suggested Teaching Plan (12 periods)
Objectives
Students will be able to:
1. Grasp the main idea (dreaming and hard work helped Michael Stone on his way to success) and the structure of the text (narration with a flashback);
2. Appreciate the narrative skills (using details to bring out a character; a surprising ending; use of puns);
3. Master the key language points and grammatical structures in the text;
4. Conduct a series of reading, listening, speaking and writing activities related to the theme of the unit
?
Time allotment
Background information
1. Sports: Sports play an important part in American life. Professional baseball and (American) football games attract large crowds, and many people watch games on television. Although many parents complain about their children being couch potatoes (=people who spend a lot of time watching television), there are sports sessions at school for all ages. College students are usually also required to take physical education classes to complete their studies.
2. Olympics: The Olympic Games are the most important international sports event in the world held every four years. The Olympic Games are organized and governed by the International Olympic Committee (IOC). It has offices in Lausanne, Switzerland. The Committee has made many decisions that affect the modern Olympics. For example, in 1912, the Committee decided to allow women to compete in the games.
Pre-reading tasks
1. T asks Ss the following questions on the song Coming out of Dark:
---- Consider the title of the song, what does “Dark” refer to? (near death; loss of consciousness after the car accident; slow and painful recovery; despair)
---- How is the song related to the theme of the unit? (to get over despair after injury is also a form of overcoming obstacles)
2. Do you know these proverbs?
1) T dictates the following proverbs to Ss:
---- Where there’s a will, there’s a way （有志者事竟成。）
---- Rome wasn’t built in a day （偉業非一日之功/羅馬非朝夕建成。）
----God helps those who help themselves （皇天不負有心人/自助者天助。）
---- You shall reap what you sow （種瓜得瓜，種豆得豆；一分耕耘，一分收獲。）
---- Constant dripping wears away the stone （鍥而不舍，金石可鏤。）
2) Ss try to translate these proverbs into Chinese;
3) Ss scan Text A to find a similar saying by Michael’s father, which is in italics (If you want something, work for it! / You want something, work for it!)
3. T may lead in to the text by saying: Hard work is important to success, but it is not the only factor that contributes to success As we will find out in this text, dreaming is equally important
?
While-reading tasks
1. Text Organization
1) T guides Ss through the directions for Text Organization Exercise 1, so that they know the text consists of four parts
2) Ss scan the first sentence of Paras 1-6, and get ready to answer the following questions:
-- Which first sentence switches from past tense to past perfect tense? (the first sentence of Para 3) (T may as well tell Ss this: a story is usually narrated in the simple past tense When a past event is recalled, the past perfect tense will be used as a signal Afterwards the flashback is also narrated in the simple past tense)
-- Which first sentence shows that the flashback is over and the narration returns to the National Junior Olympics? (the first sentence of Para 6)
-- By now, do you know how to divide the text into four parts? Write down your answers in the blanks provided in Text Organization Exercise 1
3) Ss do Text Organization Exercise 2
2. T explains language points and gives Ss practice When they come to the end of a part, Ss will sum up its main idea in the blanks provided in Text Organization Exercise 1
3. Ss answer these questions (see Text Analysis)
-- Without the last sentence, would you still admire Michael Stone’s achievement?
-- Who would you admire better, a Michael Stone with a sound body or a blind Michael Stone?
-- Why does the author keep the secret about Michael’s blindness until the last sentence?
4. Usage
1) Ss scan the text again to find out the three instances where “work” is used as a verb
2) T asks some Ss to explain in English the three different meanings of “work”
3) Ss do the after-text Usage exercise on “work”
5. Finding out details
1) T introduces the activity by saying: A child usually inherits characteristics from both his/her mother and father So does Michael Stone Michael’s mother is romantic and passionate, while his father is a hard-core realist Work with a partner, find out those details about Michael Stone that shows him to be his mother’s boy or his father’s son
2) Some Ss pairs report to class their findings
3) T asks Ss this question: Dreaming and hard work, which is more important to Michael’s success? Why?
?
Post-reading tasks
1. Playing on the meaning of words (see Text Analysis)
1) T introduces the idea that many words have more than one meaning and can remind one of a number of different ideas and events all at once
2) Ss read the first three sentences of the text to find out where the author uses a word in two different senses (the word “hot” meaning respectively “having a high temperature” and “fierce, intense”)
3) Ss give individual opinion on this question: How do you understand the title of this text? Does it also carry more than one meaning?
4) Extra reading for fun (This can be either an in-class or out-of-class group discussion The words that can recall the discoveries of the scientists are underlined): Here the poet plays on words Each line has a word or words that remind us of an activity or discovery associated with the scientist mentioned Can you spot the words?
2. T guides Ss through some after-text exercises
3. T checks on Ss’ home reading (Text B)
4. Ss do Part IV: Theme-related Language Learning Tasks
5. T asks Ss to prepare the next unit:
1) Do the pre-reading task;
2) Preview Text A
