常见考点与易错点

1. 交通方式短语混淆：

   • take a bus vs. by bus
   • on foot vs. by foot (错误)
   • take the subway vs. by subway

2. 第三人称单数：

   • 当主语是 he, she, it 或单个的人名时，动词 take 要用 takes。
   • 错误：He take the bus to school.
   • 正确：He takes the bus to school.

3. how far, how long, how 的区别：

   • How far? 问距离多远。 (回答用 kilometers, meters, minutes' walk/drive)
   • How long? 问时间多久。 (回答用 It takes... / For...)
   • How? 问方式怎么样。 (回答用 By... / On foot...)

4. between...and... 的使用：

   • 表示“在两者之间”。
   • The supermarket is between the bank and the post office.

5. get to 的用法：

   • get to + 地点 表示“到达某地”。
   • 如果地点是副词（如 home, here, there），则 get 后面不加 to。
   • I get to school at 8:00. / I get home at 5:00.
