Look,the athletes from class ten grade eight are walking towards us,vigorous and energetic.Their queues are tight and steps are steady,which show us the presence of youth; they are powerful and calm,which express thier confidence of victory; their slogan is:To let off our passion,liberate our dreams,cooperate and struggle and create briliance again.Flying freely in the high sky and proceeding forward regardless of any frustrations.Let us wish them create a new record in this games.
