　　1钢铁是怎样炼成的
　　2《钢铁是怎样炼成的》这一题目的含义：
　　奥斯特洛夫斯基在解释这部作品的标题时说：“钢是在烈火里燃烧、高度冷却中炼成的，因此它很坚固。我们这一代人也是在斗争中和艰苦考验中锻炼出来的，并且学会了在生活中从不灰心丧气。”作者在塑造保尔这一形象时，用内心独白、书信、格言警句，揭示了这一形象的内心的全部复杂性和成长过程。
　　3《钢铁是怎样炼成的》是一部描写苏联十月革命后第一代苏维埃青年在布尔什维克党的领导下，为恢复国民经济，巩固新生的苏维埃政权，同国内外敌人及各种困难进行顽强斗争的优秀小说。
　　4在本书下部的第二章写道：保尔因体弱多病，经过了无数次苦难后，最后被调去修铁路。那时正是秋冬之际，患有风湿病的保尔很痛苦。可是意志坚强的他与另一队修铁路的工人们比赛，领导朱赫来本来想过来看看他们修铁路，顺便鼓励鼓励他们。当朱赫来看到他们正在比赛修铁路时，不经叹起：钢铁就是是这样练成的！
　　5保尔
　　性格特点：热爱祖国，热爱全人类；珍惜人生，珍惜爱情、亲情和友谊；坚强勇敢，无私无畏；言行一致，说到做到，果断、利落；乐观向上，坚韧不拔，为人类的解放事业作奉献，直到生命最后一息。是一个真正的钢铁英雄汉。
　　6①x09保尔偷了邻居家的枪，哥哥阿尔焦姆帮他砸毁了枪才逃过一切。
　　②x09朱赫来被白匪军抓了，保尔把匪兵打倒在沟里，他们一起逃走了。后来因为波兰贵族列辛斯基的儿子告密，保尔被关进监狱，又被当做普通犯人错放了。
　　③x09在一次激战中，被炮弹击中头部，入住疗养院休养。
　　④x09在筑路工作要结束时，保尔得伤寒，不得不把他送回家休养。半路上误传出保尔已经死去的讯息，但保尔第四次战胜死亡回到了人间。

选 D 哦 嘿嘿 很确定 我们做过

demand urgently for …
need… urgently

设直角三角形中20cm边所对的角为A 则 tanA=20/40 可以求出角A的度数 那么 也就可以求出sinaA的值了 设斜边为X 则 sinA=20/x 即x=20/sinA

5.关于图中信息的解读,正确的是：选B
A.距流域出口越远,汇流时间越长
B.北支流的流速比南支流的流速慢
C.等流时线越密,说明流速越快
D.等流时线平直,说明地形坡度变化大
流速＝流程/时间
北支流汇入干流的时间大约是1到3小时之间,南支流汇入干流的时间大约是1到3小时之间,2到4小时之间,而南支流的长度是北北支流2倍,而时间不到北支流的2倍,所以答案是B

A、根据质量数和电荷数守恒可知，两个氘核聚变成一个
32 He所产生的另一个粒子为中子 ₀ ¹ n，故A正确；
B、两个氘核聚变成一个
32 He所释放的核能为（2m ₁ -m ₃ -m ₂ ）c ² ，故B错误；
C、福岛核电站是采用的是重核裂变释放能量的进行发电的，故C错误；
D、受控核聚变优点很多：一是其应用的材料在海水中取之不尽，原料来源更加丰富；二是反应生成物为水，不会对自然造成污染，故D正确．
故选：AD．

This article strengthens the cost management in view of the current construction enterprise competition intense objective reality and the construction enterprise the urgent need,from aspects and so on cost management's concept principle,characteristic,competitive spirit,risk guard consciousness and new cost management idea obtained,to elaborate in the construction private costs management existed question and countermeasure.

1、句子杂糅
专家呼吁尽快淘汰二冲程燃油助力车,这是当前形势的迫切需要.
2、选A,第一句没有问题
第二局,张华说,最后一个球没有踢好,说的是我们,所以后面应该把我们放在前面.主语要一直

This problem calls for immediate solution.

求分!

将7写成根号2的平方加根号5的平方,2倍根号10写成2倍的根号5乘以根号2,这样就构成了一个完全平方式,即根号下（根号5加根号2）的平方,开平方根后,最终结果是根号5加根号2.

解题思路：正确解答该题需要掌握：目前核电站的能量来自重核裂变；根据质量数和电荷数守恒判断核反应的产物；正确应用质能方程求解核反应过程中产生的能量；了解聚变和裂变的区别．

A、根据质量数和电荷数守恒可知，两个氘核聚变成一个
32He所产生的另一个粒子为中子₀¹n，故A正确；
B、两个氘核聚变成一个
32He所释放的核能为（2m₁-m₃-m₂）c²，故B错误；
C、福岛核电站是采用的是重核裂变释放能量的进行发电的，故C错误；
D、受控核聚变优点很多：一是其应用的材料在海水中取之不尽，原料来源更加丰富；二是反应生成物为水，不会对自然造成污染，故D正确．
故选：AD．

点评：
本题考点： 爱因斯坦质能方程．

考点点评： 本题比较简单，主要考查了核聚变方程的书写以及质能方程的应用，同时要了解有关核能的利用．

1这篇文章辩证的回答了,在大开放、大发展、大融合的世界里,我们迫切需要用一种全新的观念来协调各种关系的问题.

这是Edwina Matthews 的诗,《Beauty》
Beauty is in the eyes of the beholder.
Beauty is in all things.
Beauty is in the sky.
Beauty is in the water ever so blue.
Beauty is the winter when trees are covered with snow.
Beauty is the summer when you smell and see the flowers grow.
Beauty is all things big and little.
Beauty is in all things,
Black and white.
Beauty is in all things,you and me.
Beauty is all around us...can't you see?
Beauty is seen
In the sunlight,
The trees,the birds,
Corn growing and people working
Or dancing for their harvest.
Beauty is heard
In the night,
Wind sighing,rain falling,
Or a singer chanting
Anything in earnest.
Beauty is in yourself.
Good deeds,happy thoughts
That repeat themselves
In your dreams,In your work,
And even in your rest.
