1、 shú 第⼆声 rǔ 第三声 zhì 第四声
2、 ① ② ② ② ③
3、全国 擅长 下棋 教导 引，拉 ⼀起
课⽂记叙了两个⼈跟弈秋学下围棋，⼀⼈专⼼致志，⼀⼈三⼼⼆意，结果第⼆个⼈不如第⼀个⼈学得好。这个故事告诉我们学习应该专⼼致志，不能三⼼⼆意的道理。 是因为他的智⼒不如前⼀个吗？说：不是这样的。
原因 热⽔ 判断 谁
⼀个⼩孩认为太阳刚出来是离⼈远，⽽正午时离⼈近。
谁说你的知识渊博呢？
孔⼦不能决也 观察 善于观察，善于思考 ，说话有理有据 谦虚、谨慎、实事求是
①知之为知之，不知为不知，是知也。
②有朋⾃远⽅来，不亦乐乎？
三⼈⾏必有我师焉 ⼰所不欲，勿施于⼈
4、⼩练笔
《学弈》这篇课⽂，让我感触最深。⽂章通过让弈秋教两个⼈下棋，告诉我们在同样条件下不同的态度会得到不同的结果，所以我们学习必须专⼼致志，决不可三⼼⼆意。就如我们班的同学，为什么同样坐在教室⾥，同样的⽼师，成绩会有差异？其实不是智⼒的差别，⽽是专⼼与勤奋程度不同的原因。

在括号⾥填上合适的词语。这些词语写出了时间飞逝的特点。
“叹息”是叹⽓的意思，作者叹息是因为作者觉得时间过得飞快，在已逝的时光中没有作为，所以作者要叹息。
