many times表示“很多次，很多倍”。如果表示多次，一般用于完成时态。请看以下例句。
He has been to the local museum many times. 本句使用了现在完成时态。再看第二个句子，He told me that he had been to the local museum many times.此时，原句被放在主句之后，相当于把直接引语变为间接引语，从句的时态就变为过去完成时态。
现在完成时 He has done this many times. 他已经干了许多回了。She has been to England three times. 岛国英格兰三次。
