练题示例以下是练题的示例，题目没有给出答案，请学生们自行计算。
1. 0.8 + 0.3 =2. 1.5 - 0.7 =3. 3.2 + 2.1 =4. 4.6 - 1.9 =5. 6.7 + 3.4 =6. 7.9 - 4.5 =（题目略）练方法1. 学生们可以每日按照时间分配，完成一定数量的题目，逐渐增加难度和数量。
2. 在解答题目之前，可以先仔细阅读题目中的数字，并理解加减法的运算规则。
3. 在计算过程中，可以借助计算器或计算软件，但建议尽量凭借自己的能力进行口算。
4. 在解答完所有题目之后，可以对照答案进行核对，找到自己存在的错误，并进行纠正。
研究建议1. 鼓励学生们保持良好的研究惯，每天坚持一定时间的口算练，培养数学思维和计算能力。
2. 提醒学生们注意小数加减法运算时的进位和借位，避免出现错误的计算结果。
3. 鼓励学生们在研究过程中积极思考，尝试使用不同的解题方法，提高思维灵活性。
4. 针对学生们容易出错的题型，可以进行重点讲解和针对性练，加强弱项。
总结这份练题旨在帮助五年级学生们提高小数加减法口算能力，通过大量的练题目，培养他们的数学思维和计算能力。
希望学生们能够坚持不懈地练，掌握小数加减法的运算规则，为进一步研究数学打下坚实的基础。
