【答案】Recently，lacking in self-confidence，many students are becoming anxious and nervous during the stressful and busy preparation for the exam review.So it's high time that we should build up our self-confidence.
    When we are faced with new challenges，we may feel nervous and be not sure whether we can make it.But we must have confidence，because only when we have it can we have the belief that we can achieve our dream.It's more than important that we build up our self-confidence if we don't have it.For example，we can take part in more physical labor or some sports.They can make us full of energy and have a high spirit.On that condition，we'll say goodbye to inferiority and be confident.
