一般现在时讲解与习题 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’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。 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. 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。 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。” 自我检测 ： (一)、 单选 答案：1 B 2D 3C 4B 5B 6B 1 Jenny ____ in an office.
