植树问题专项练习一（植树）普通植树包含两端都种、一端种一端不种和两端都不种题型。

1.两端都种公式：棵数＝总长÷间距＋1 总长＝间距×（棵数－1）特点：题目中含有“两端都种”或“从头到尾”等字样。

2.一端种一端不种公式：棵数＝总长÷间距总长＝间距×棵数特点：题目中含有“一端种一端不种”等字样。

3.两端都不种公式：棵数＝总长÷间距－1 总长＝间距×（棵数＋1）特点：题目中含有“在……之间”或“两端不种”等字样。

特别提示：此种题型一定要注意是在一侧．．种。

．．种，还是两侧例1：有一条长2000米的公路，在路的两边每相隔5米栽一棵白杨，从头到尾需要栽白杨多少棵？分析：题目中有“从头到尾”几个字，可以判断此题为两端都种的情况，看问题求“多少棵”可知是求棵数，应利用公式“棵数＝总长÷间距＋1”，另外题目中有“两边”字样，因此最后求得的结果需乘2。

列式：（2000÷5＋1）×2＝802（棵）例2：两座楼房之间相距56米，每隔4米栽雪松一棵，一行能栽多少棵？分析：题目中有“两座楼房之间”几个字，可以判断此题为两端不种的情况，看问题求“多少棵”可知是求棵数，应利用公式“棵数＝总长÷间距－1”。

列式：56÷4－1＝13（棵）练习1.在一段公路的一旁栽95棵树，两头都栽。

每两棵之间相距5米，这段公路长多少米？练习2.某大学从校门口的门柱到教学楼墙根有一条长800米的甬路，每边隔5米栽一棵梧桐树，需要梧桐树多少棵？练习3.在一条全长2千米的街道两旁安装路灯（两端也要安装），每隔50米安一座。

一共要安装多少座？练习4.学校两座教学楼之间的如果每隔5米种1棵树，可以种7棵，两座教学楼之间长多少米？练习5.小学生广播操队列中，其中一列纵队26米，相邻两个学生之间的距离是2米。

这列纵队一共有几个学生？练习6.园林工人沿公路一侧植树，每隔6米种一棵，一共种了36棵。

初级节奏练习题音乐中的节奏是一种重要的元素，它决定了音乐的演奏速度和节奏感。

对于音乐初学者来说，掌握良好的节奏感是非常重要的。

本文将提供一些初级节奏练习题，帮助初学者提高节奏感和准确性。

练习一：节拍练习在音乐中，节拍是整个曲子的基础，练习节拍可以帮助我们更好地掌握音乐的整体感觉和准确性。

以下是一些节拍练习题：1. 使用节拍器或节拍器应用程序，设定一个稳定的呼吸节拍，例如60拍/分钟。

尝试以此节拍频率拍手或跺脚。

2. 在钢琴或其他乐器上，使用一个简单的和弦进行，例如C大和弦。

按照设定的节拍频率演奏和弦。

3. 使用节拍器，设定一个稍快的节拍，例如120拍/分钟。

尝试使用双手或其他乐器演奏简单的节奏模式，如4/4拍的四分音符。

练习二：节奏模式练习除了掌握节拍外，了解并练习不同的节奏模式也非常有助于提高节奏感和表演技巧。

以下是一些节奏模式练习题：1. 使用节拍器或节拍器应用程序，设定一个适中的节奏，例如80拍/分钟。

尝试演奏经典的节奏模式，如齐舞蹈、华尔兹或迪斯科。

2. 在钢琴或其他乐器上，尝试演奏不同的节奏模式，如三连音、十六分音符或八分音符。

注意保持稳定的节拍并准确演奏每个音符。

3. 使用节拍器，设定一个较快的节拍，例如140拍/分钟。

尝试演奏一些挑战性的节奏模式，如交叉手指或跳音符。

练习三：节奏演奏练习除了简单的节拍和节奏模式练习外，我们还可以尝试一些更具挑战性的节奏演奏练习。

以下是一些练习题：1. 使用节拍器或节拍器应用程序，设定一个稍快的节奏，例如100拍/分钟。

尝试演奏一些复杂的节奏模式，如变拍或多节奏模式。

2. 在钢琴或其他乐器上，尝试演奏一些节奏复杂的曲目，如巴赫的赋格曲或肖邦的练习曲。

3. 使用节拍器，设定一个较快的节奏，例如160拍/分钟。

尝试演奏一些具有节奏挑战性的曲目，如贝多芬的奏鸣曲或雷蒙·韦伯的序曲。

通过以上的节奏练习，初学者们可以更好地掌握节奏感和准确性。

当然，节奏训练需要持续的努力和练习，不断地挑战自己，才能达到更高的水平。
