七年级英语专题训练（一）一、一般现在时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. 一般现在时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 dont have lunch at 12:00. Do they have lunch at 12:00? 2）第三人称单数做主语的，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。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?一般现在时其时间状语为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 (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。”、 单选1 Jenny _ in an office.

But this cat ate a bird last night and the bird was worth 80 dollars!”找出不可数名词，在横线上打勾，并将可数名词变成复数形式： homework _half _advice_money _knowledge _boot _blood _music _chicken _heat _mouth _bread _information _milk _cow _tear _3、选择填空：1The deer has four _.A. foot B. feet C. feets D. foots2Her two brothers are both _.A. policeman B. policemans C. policemen D. policemens3There are four _ and two _ in the group.A.
