front crawl

基本解释

As such the term freestyle is often used as a synonym for the front crawl.
因此人们常说的“自由泳”基本就成了“爬泳”的同义词。
I've always been suspicious of baby education, of teaching them the front crawl at six weeks or Mozart in the womb, but this was different, mainly because it was really aimed at the parents.
我一直都对婴儿教育心存疑虑，对于在他们六个月大时教他们自由泳，当他们还在妈妈肚子里时给他们放莫扎特的音乐而心存怀疑。但是这次不一样，很大程度上是因为这个课是针对父母的。
While other styles like the breaststroke, front crawl, or backstroke can be swum easily even by beginners, the butterfly is a more difficult stroke that requires good technique to be feasible.
初学者也许能很容易地掌握蛙泳、自由泳或仰泳，但蝶泳却难得多，对游泳者的技术要求很高。
