    Yesterday our club held an English speech contest, which theme was “Challenge Myself”. A large number of students attended to the contest and showed their wonderful performances. In the stage, though face great pressure, the speakers bravely overcame it and challenged them to achieve great success. Moreover, they impressed us deep with their unusual confidences and performances.

    Through such activity, we know a lot more about our students but we have gained much, such as self-confidence and bravery. Besides, our club was growing stronger.
