⑥ 中国学生 5 大高频错误诊断
错误 1：use...to 后面加 doing ✗ I use my phone to chatting. → ✓ I use my phone to chat. use sth to do，to 后动词原形。若用 for 则是 for chatting。
错误 2：call 后面加 to ✗ I'll call to you later. → ✓ I'll call you later. call 是及物动词，直接加人。
错误 4：只说好处不说转折 ✗ Technology is good.（就结束）→ ✓ Technology is useful, but sometimes it's too much. 口语加 but 转折，立刻显成熟。
错误 5：How do I...? 后动词不原形 ✗ How do I turning on the TV? → ✓ How do I turn on the TV? 助动词 do 后动词永远原形。
