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。 　　???? 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 　　1 Jenny ____ in an office.?
