一般现在时是英语中应用最广泛的时态之一，是中考复习的重点。它表示： (1)经常性、习惯性的动作或存在的状态。e.g. 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。e.g. He can swim. I work hard. I like watching TV. (3)表示客观真理 e.g. 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? 含有be动词的要在be上做变化. E.g. Danny is a good student. Danny isn’t a good student. Is Danny a good student? 其时间状语为often、 usually、 always、 sometimes等频率副词，on Saturdays、 in the morning(afternoon evening) 、every day 等。 做题时常见错误如下： 一、be动词与行为动词同时出现在句子中 例：We are plant 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。” 专项练习： 一、 单选 1 Jenny ____ in an office.
