32、 like,has,go,comes,wants,drives,to work,goes,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 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。”,二、单三人称形式易出错 例：1 He plaies (play) football very well. 2 Danny gos (go) to school at 7:10.,答

33、案：1 plays 2 goes 以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es； 与名词变复数不同，变单三人称形式以o结尾的词要加es.,三、在句式变换时易出错 1 Does Jenny has (has) a good friend? 2 Brian doesnt lives (not live) in China.,答案：1 Does have 2 doesnt live 单三人称做主语的一般现在时做句式变化时，记住：“见助动，用原形”。也可推广用于一般过去时态中。 e.g. He didnt go home yesterday.,四、对do的理解易出错 例：We dont

34、 (not do) our homework in the afternoon.,答案：dont do Do 是助动词，无实义； 是一个具体的行为动词“做，干”。 此句中给出的do指“做，干”，故须在do前加助动词dont。,五、对主语的数判断有误 例： Li Ming with me are (be) in Beijing.,答案: is 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.,1._ you have a book ? A Do B. Are C. Is D. Have 2.Does Li Lei like to watch TV? _.
