一般现在时是英语中应用最广泛的时态之一，是初中英语语法重点。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变一般疑问句须在句首加助动词do。 E.g. They have lunch at 12:00. They dont 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变一般疑问句须在句首加助动词does。 E.g. Jenny speaks English very well. Jenny doesnt 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 isnt 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。 |
