Answer 1

分析 Did Tom spend at most half an hour practicing playing baseball？

解答 答案：Did Tom spend at most half an hour practicing playing baseball？表達(dá)的是過去的動(dòng)作故用一般過去時(shí)，這里是一般疑問句，花時(shí)間做某事spend+時(shí)間+doing sth，借助于did構(gòu)成一般疑問，at most half an hour 至多半小時(shí)，practice doing sth連詞做某事，故答案是Did Tom spend at most half an hour practicing playing baseball？
