1、语文园地四,关键语句能帮助我们概括一段话的大意。如，富饶的西沙群岛中的“西沙群岛也是鸟的天下”这句话，直接写出了第5自然段的大意。,西沙群岛也是鸟的天堂。岛上有一片片茂密的树林，树林里栖息着各种海鸟。遍地都是鸟蛋。树下堆积着一层厚厚的鸟粪，这是非常宝贵的肥料。,西沙群岛也是鸟的天堂。,活动一：再会老朋友,板块一 交流平台,有时候，一段话的大意需要根据关键语句的提示进行概括。如，根据花钟第2自然段的第1句话的提示，这个自然段的大意可以概括为：植物开花的时间与温度、湿度、光照、昆虫活动的时间有关。,不同的植物为什么开花的时间不同呢？有的植物开花的时间，与温度、湿度、光照有着密切的关系。比如，昙花的
2、花瓣又大又娇嫩，白天阳光强，气温高，空气干燥，要是在白天开花，就有被灼伤的危险。深夜气温过低，开花也不适宜。长期以来，它适应了晚上九点左右的温度和湿度，到了那时，便悄悄绽开淡雅的花蕾，向人们展示美丽的笑脸。还有的花，需要昆虫传播花粉，才能结出种子，它们开花的时间往往跟昆虫活动的时间相吻合。,春天在哪里呢?春在枝头，柳条嫩绿，桃花鲜艳。春在空中，和风送暖，燕子翻飞。春在水里，鱼儿追逐，鸭子戏水。春在田间，麦苗返青，菜花金黄。到处都有春天，春满人间。,关键语句可能在一段话中的不同位置。如，花钟第1自然段的关键句是第2句话，小虾第3自然段的关键句是第1句话。,有时候，需要根据关键语句的提示进行概括；
3、关键语句可能在一段话中的不同位置。, 鲜花朵朵，争奇斗艳，芬芳迷人。要是我们留心观察，就会发现，一天之内，不同的花开放的时间是不同的。凌晨四点，牵牛花吹起了紫色的小喇叭；五点左右，艳丽的蔷薇绽开了笑脸；七点，睡莲从梦中醒来；中午十二点左右，午时花开放了；下午三点，万寿菊欣然怒放；傍晚六点，烟草花在暮色中苏醒；月光花在七点左右舒展开自己的花瓣；夜来香在晚上八点开花；昙花却在九点左右含笑一现,活动二：看谁找得快,缸里的小虾十分有趣。它们有的独自荡来荡去，有的互相追逐，有的紧贴住缸壁。要是你用小竹枝去动动那些正在休息的小虾，它们会立即向别的安静的角落蹦去，一路上像生了气似的，不停地舞动着前面那双细长
4、的腿，腿末端那副钳子一张一张的，胡须也一翘一翘地摆动着，连眼珠子也一突一突的。如果这时碰到正在闲游的同伴，说不定就要打起来。小虾的搏斗很激烈，蹦出水面是常有的事，有时还会蹦到缸外的地面上。,本次交流的内容是如何找一段话的关键句，也就是中心句。因为这段话都是围绕这个中心句来叙述的，关键句有时在一段话的开头，有时在中间，有时在结尾，我们可以用这个关键句来概括这段话的主要内容，有时可以稍作改动。,交流指导：,我的周末生活过得可有意思了！有时候我会在图书馆（ ）地（ ） ，有时候我会在公园里（ ）地（ ），有时候我会在体育馆里（ ）地（ ），还有时候（ ）。,活动三：妙招我会用, 院子里的花儿和小草都
5、被晒蔫了，无精打采地垂着头；树上的叶子打起了卷，失去了往日的光泽；小狗扑在地上吐着舌头，“扑哧扑哧”地喘着气。（ ）。,（ ），有时候，妈妈的爱表现得却不太一样，（ ）。,小明是我们班同学学习的榜样。,围绕句子进行说话比赛。,围绕“春天的田野”写一段话。,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才
