Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews.

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

北师大初中数学八年级上册二次根式及其化简1教案
方法总结：(1)若被开方数中含有负因数，则应先化成正因数，如(3)题．(2)将二次根式尽量化简，使被开方数(式)中不含能开得尽方的因数(因式)，即化为最简二次根式(后面学到)．探究点三：最简二次根式在二次根式8a，c9，a2＋b2，a2中，最简二次根式共有()A．1个 B．2个C．3个 D．4个解析：8a中有因数4；c9中有分母9；a3中有因式a2.故最简二次根式只有a2＋b2.故选A.方法总结：只需检验被开方数是否还有分母，是否还有能开得尽方的因数或因式．三、板书设计二次根式定义形如a（a≥0）的式子有意义的条件：a≥0性质：（a）2＝a（a≥0），a2＝a（a≥0）最简二次根式本节经历从具体实例到一般规律的探究过程，运用类比的方法，得出实数运算律和运算法则，使学生清楚新旧知识的区别和联系，加深学生对运算法则的理解，能否根据问题的特点，选择合理、简便的算法，能否确认结果的合理性等等．
北师大初中数学八年级上册二次根式及其化简2教案
属于此类问题一般有以下三种情况①具体数字，此时化简的条件已暗中给定，②恒为非负值或根据题中的隐含条件，如（1）小题。③给出明确的条件，如（2）小题。第二类，需讨论后再化简。当题目中给定的条件不能判定绝对值符号内代数式值的符号时，则需讨论后化简，如（4）小题。例3．已知a+b=-6,ab=5，求 的值。解：∵ab=5>0,∴a,b同号，又∵a+b=-6<0,∴a<0,b<0∴ .说明：此题中的隐含条件a<0,b<0不能忽视。否则会出现错误。例4．化简： 解：原式=|x-6|-|1+2x|+|x+5|令x-6=0，得x=6，令1+2x=0，得 ，令x+5=0，得x=-5.这样x=6, ,x=-5，把数轴分成四段（四个区间）在这五段里分别讨论如下：当x≥6时，原式=(x-6)-(1+2x)+(x+5)=-2.当 时，原式=-(x-6)-(1+2x)+(x+5)=-2x+10.当 时，原式=-(x-6)-[-(1+2x)]+(x+5)=2x+12.当x<-5时，原式=-(x-6)+(1+2x)-(x+5)=2.说明：利用公式 ，如果绝对值符号里面的代数式的值的符号无法决定，则需要讨论。方法是：令每一个绝对值内的代数式为零，求出对应的“零点”，再用这些“零点”把数轴分成若干个区间，再在每个区间内进行化简。
