Unit 4 Astronomy the science of the stars教案（人教版必修3）Period 5Using language: Extensive reading整体设计教材分析This is the fifth teaching period of this unit. As usual, the teacher should check students’ homework and offer chances for them to go over what they learned in the last period at the beginning of the class. Then lead in the new lesson.In this period, the teaching emphasis will be put on developing students’ reading ability by reading extensively. We will deal with two parts: A VISIT TO THE MOON in Using language on Pages 30-31 and CAUGHT BY A BLACK HOLE in Reading Task on Page 66. While reading, get students learning to use some reading strategies such as skimming, scanning, and so on. As to new words and phrases, the teacher can first find those students feel most difficult and help them to understand. That’s enough here. The reading passage A VISIT TO THE MOON is a science fiction story which imagines what it might be like if an astronaut visited the moon. The purpose of science fiction writing is to combine facts with a story to make students interested and excited about travel in space. It is also to stimulate awe and wonder into the vastness of space. As this reading uses the information students have gained from the listening, the teacher can first ask some students to retell the listening text to lead in the topic and then ask students to read the passage and do some comprehending exercises. While checking their answers with the whole class, deal with language problems students can’t work out by t hemselves. This is an extensive reading lesson, so the teaching steps should be simple. As to the passage CAUGHT BY A BLACK HOLE, it is to continue the above story. The astronomers in the story visit a place in space, which seems impossible for people to reach, the “black hole”. It is to help students imagine what it is like near a “black hole”. Ask students to read through the passage and try to know more about astronomy and gravity.At the end of the class, ask students to retell the two passages. In order to arouse students’ interest, the teacher can hold a competition among them.教学重点1. Develop students’ reading skills by extensive reading.2. Let students read and understand the two passages.教学难点1. Enable students to learn to use reading strategies such as skimming, scanning, and so on.2.

Ask students to read the passage and then describe the three ways in which gravity changed for Li Yanping and how his weight changed.1) Write down the three ways in which gravity changed for Li Yanping.The way gravity changedLeft the earthIn spaceOn the moonSuggested answers:The way gravity changedLeft the earth The gravity became very strong.In space The gravity disappeared.On the moon The gravity became very light.2) His weight changed three times, too. Now write them down.How his weight changedLeft the earthIn spaceOn the moonSuggested answers:How his weight changedLeft the earth He became very heavy.In space He had no weight and could float around like a feather.On the moon He was about one-sixth of his weight on the earth.2. Ask students to read the passage aloud to the tape and underline all the useful expressions or collocations in the passage. Let students read them aloud and copy them down in their exercise book after class as homework. Try to keep them in mind.Collocations: be lucky enough to do, have a chance, make a trip into space, explain sth. to sb. , the force of gravity, be off, the pull of the earth’s gravity, fall back to the earth, fall to theground, too far from the earth, as if, at all, get close to, cheer up, come on, less than, down the steps, step forward, twice as far as, fall over, a bit of, now that, after a while, get the hang of, break out, on the outside of, be pushed into→Step 4 Important language points1.

What the teacher said today was
quite right.
老师今天说的话是十分正确的。
2) 由连词that引起的主语从句：
That they are badly in need of help is
quite clear.
他们急需帮助，这是十分明显的。
但是这类句子在大多数情况下会放到整
1. _____ That you don’t like him is none of my business. 2. _____ What he said at the meeting astonished everybody present. 3. ________ Whether the 2000 Olympic Games will be held in Beijing is not known yet. 4. ________ Whether we’ll go camping tomorrow depends on the weather. 5. ________ Whoever leaves the room last ought to turn off the lights.
个句子的后部去，而用代词it作形式主语。
3) 由连接代词或连接副词以及whether
引起的主语从句。
Whether they will sell the house is
not yet decided.
他们是否卖掉这所房子还没有决定。
4) whatever, whoever也可引导主语从句。 Whatever was said here must be kept secret.
主语从句 （Noun Clauses as the Subject）
定义： 用作主语的从句叫主语从句，它是名 词性从句之一。引导主语从句的连接词有： 连词that, whether；连接代词who,
what和which；连接副词when, where, how和why。
பைடு நூலகம்
用法：
1) 由what等代词引起的主语从句：
这里说的话都应当保密。
Whoever makes mistakes must correct them.
凡犯了错误的人都必须改正。
注意: 上述例句中的主语从句都是放在
句首, 但有时为了使句子结构平衡, 避免 “头重脚轻”, 常用 it 作形式主语, 而 把从句放在后面。 例如:
It is a pity that she has made
such a mistake.
她犯了这样一个错误, 真是遗憾。
这样就构成了下面一些常用句型:
1) It is + adj. / n. +从句 It is a pity/shame that... 遗憾的是…… It is possible that... 很可能…… It is unlikely that... 不可能…… 2) It +不及物动词+从句 It seems/appears that... 似乎…… It happened that... 碰巧……
