那要看你想要着重表达什么了.如果你想说你从2月才开始学,就用l started learning English this February或者I started to learn English this February. 两个表达差不多,但是前面的要表示"你还在学"的持续性更强一些.
如果你想说你从2月已经学了,并且现在已经会一些了可以说:l've started learning English this February.
I started to learn English this February.
I began to learn English this year .
February of this year did I start to learn English
It was February in this year I began learning English.
