问题 Jack loves sports. He is often seen __________ basketball on the school playground.

选项 A.play B.playing C.plays D.to play

答案 B

解析 see的用法为see sb．do或者是see sb．doing，该句是被动语态，意思为“他经常被看见在学校操场打篮球”。这里强调的是这一刻人们看见他正在打篮球的这一幕，故选B。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
