一般现在时在英语中学习中，是应用最多的一个时态，也是最基础的时态，是初中英语学习中的重点内容，在考试中经常会出现。所学生们对一般现在时一定要重视，在搞懂一般现在时的内容之后，多做一般现在时练习题才能真正掌握这个时态中的所有知识。
首先要了解它的定义是什么，掌握住什么情况下会用到这个时态。
1、行为动词一般现在时的用法：
1)概念：经常性、习惯性的动作或存在的状态。eg. I go to school on foot. He is very busy now.
2)表示主语的特征、性格、能力、爱好等。eg. He can swim. I work hard. I like watching TV.
3)表示客观真理 eg. There are seven days in a week. The moon moves round the earth.
其结构按正常语序，即“主语+谓语+其它”，有时为了起强调作用，时间状语也可提前.
其句式变化可分为两种情况
1)表示动作，一般人称作主语的，变否定句须在动词前加助动词don’t;变一般疑问句须在句首加助动词do。 E.g. They have lunch at 12:00. They don’t have lunch at 12:00. Do they have lunch at 12:00?
2)单三人称做主语的，变否定句须在动词前加助动词doesn’t;变一般疑问句须在句首加助动词does。
E.g. Jenny speaks English very well.
Jenny doesn’t speak English very well.
Does Jenny speak English very well?
行为动词的一般现在时常和表示经常性的时间状语连用：如often、 usually、 always、 sometimes等频率副词，on Saturdays、 in the morning(afternoon evening) 、every day 等。
2、系动词be一般现在时的用法
结构：主语+系动词(be--am\is\are)+表语
E.g. Danny is a good student.
Danny isn’t a good student.
Is Danny a good student?
系动词随主语的变化而变化，口诀：我I用am，你you用are,is用于她she他he它it，其余一律都用are.
以上就是一般现在时的讲解以及它的结构介绍，相信大家对于该时态都有所了解了.
学生常见错误如下：
一、be动词与行为动词同时出现在句子中
例：We are plant (plant) the trees in spring.
答案：plant
解析：学生往往会用汉语的思维方式去翻译，就成了“我们是在春天植树”。这是学习英语最忌讳的，要看语法是不是正确，在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，
可记住如下口诀：“英汉语言有差异，be 、do不能放一起，仔细琢磨细分析，语法千万要牢记。”
