7、ear_ _ hold_ _hurt_ _keep_ _know_ _ lay_ _本次课的新内容：时态一 一般现在时：1.意义：1)表示现在经常性、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)表示主语现在的特征、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 e.g. There are seven days in a week.The moon moves round the earth.2.动词的结构：be动词: am
8、is are实义动词：do（指动词原形），does（指动词的第三人称单数形式）动词原形如何变为第三人称单数形式：3标志词：often、 usually、 always、 sometimes等频率副词，on Saturdays、in the morning(afternoon evening) 、every day 等。4其句式变化可分为两种情况 1)当动词是实义动词时 非第三人称单数作主语的，变否定句须在动词前加助动词dont；变一般疑问句须在句首加助动词do。 E.g.They have lunch at 12:00.They _ have lunch at 12._they _ lunch
9、 at 12:00? 三单人称做主语的，变否定句须在动词前加助动词doesnt；变一般疑问句须在句首加助动词does。并要把动词的三单形式改为原型。E.g.Jenny speaks English very well.Jenny _ speak English very well._Jenny _ English very well?2)含有情/be动词的要在情/be上做变化. E.g.Danny is a good student. Danny _ a good student._ Danny a good student?5.学生常见错误如下：be动词与行为动词同时出现在句子中例：We a
10、re 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。”三单人称形式易出错:例：1 He_ (play) football very well.2 Danny _ (go) to school at 7:10.解析：1以辅音字母加y结尾的动词变单三人称形式才能把y成i再加es；2与名词变复数不同
11、，变单三人称形式以o结尾的词要加es.在句式变换时易出错:例1 Does Jenny_ (has) a good friend?2 Brian _ (not live) in China.解析：单三人称做主语的一般现在时做句式变化时，可记住下口诀：“见助动，用原形”。此口诀也可推广用于一般过去时态中。e.g. He didnt go home yesterday.对do的理解易出错:例：We _ (not do) our homework in the afternoon.解析：do是一个比较难理解的词，它有三个含义: a)是所有行为动词的总称；b)是助动词，无实义；c)是一个具体的行为动词“
12、做，干”。此句中给出的do指“做，干”，not指把此句变为否定句，故须在do前加助动词dont。对主语的数判断有误例： Li Ming with me_ (be) in Beijing.解析:表面一看是“我和李明两个人在北京”，但with在此做伴随状语，不能做主语，故用is.另外，宾语从句中，从句部分若是表示客观真理，不管主句是何时态，从句都要用一般现在时；在时间和条件状语从句中，主句表将来，从句要用一般现在时。6.自我检测：(一)、 单选1 Jenny _ in an office. Her parents _in a hospital.A work; works B works; work
