知识点1：乘坐交通工具的表达
在小学英语中，乘坐交通工具的表达主要有两种核心结构 （一）by + 交通工具（最常用，简洁通用）结构：by + 交通工具名词（单数，不加冠词a/an/the）用法：通常放在句子末尾，作方式状语，回答“Hw d yu g ”的提问。常见搭配（译林版四五年级重点）：- by bike 骑自行车- by bus 坐公交车- by car 坐小汽车- by train 坐火车- by plane 坐飞机- by ship 坐轮船- by metr 坐地铁
（二）take + 交通工具（强调“乘坐”的动作）结构：take + a/an/the + 交通工具名词（单数，需加冠词）用法：放在句子中间，作谓语动词，有人称和时态变化（第三人称单数作主语时，take变takes）。例句：- I take a bus t schl.（我坐公交车去上学。= I g t schl by bus.）- My father takes a car t wrk.（我爸爸坐小汽车去上班。= My father ges t wrk by car.）- They take the train t Beijing.（他们坐火车去北京。= They g t Beijing by train.）

知识点2：情态动词can
（一）can的基本含义1. 表示“能；会”：用来描述某人具备的能力，相当于中文的“会做某事”。这是课本中最核心的用法。例句：I can swim.（我会游泳。）/ She can speak English.（她会说英语。）2. 表示“可以”：用来表达请求许可或允许别人做某事，语气委婉。例句：Can I use yur pen?（我可以用一下你的钢笔吗？）/ Yu can g nw.（你现在可以走了。）
（二）can的句型结构（重点！）1. 肯定句：主语 + can + 动词原形 + 其他结构特点：can后面必须跟动词原形，无论主语是单数（he/she/it）还是复数（I/we/they），can都不变形。例句：- My brther can play ftball.（我弟弟会踢足球。）2. 否定句：主语 + can't + 动词原形 + 其他结构特点：can的否定形式是can't（= can nt），同样跟动词原形，语气直接。例句：- I can't ride a bike.（我不会骑自行车。）- She can't sing English sngs.（她不会唱英文歌。）
3. 一般疑问句：Can + 主语 + 动词原形 + 其他？结构特点：把can提到句首，首字母大写，句末用问号；回答用“Yes, 主语 + can.”或“N, 主语 + can't.”。例句及答句：- Can yu dance?（你会跳舞吗？） -Yes, I can.（是的，我会。）/ N, I can't.（不，我不会。）- Can he swim?（他会游泳吗？） -Yes, he can.（是的，他会。）/ N, he can't.（不，他不会。）

They are in the art club.A. draws B. drawing C. draw
知识点3：动词开头祈使句用法
动词开头的祈使句是小学英语中常用的句型，主要用来表达“命令、请求、建议或提醒”，祈使句的两种基本结构1. 肯定祈使句（表命令、请求、建议）结构1：动词原形 + 其他成分（最基础，日常指令常用）例句：- Open the dr.（打开门。）注意：形容词前的be动词要用原形——be 例句：Be quiet, please. (请安静。)2. 否定祈使句（表禁止、提醒不要做某事）结构：Dn't + 动词原形 + 其他成分（Dn't是D nt的缩写，小学阶段重点掌握）例句：- Dn't pen the windw.（不要开窗。）
