“爸爸教我游泳”可以用“Dad taught me to swim.” 或者 “My father taught me how to swim.” 来表达。
“taught”是“teach”的过去式,“teach sb. to do sth.”表示“教某人做某事”,所以“Dad taught me to swim.” 意思是“爸爸教我游泳”。
而“how to do sth.”是“如何做某事”的常用结构,“My father taught me how to swim.” 则更加强调“教我如何游泳”。
这两种表达方式在语法和语义上都是正确的,可以根据具体语境和表达需要进行选择。例如:Yesterday, Dad taught me to swim in the pool. (昨天,爸爸在游泳池教我游泳。) 或者 My father taught me how to swim when I was six. (我六岁时爸爸教我如何游泳。)
