②this和these表示所指的人或物距离说话人比较近，而that和those表示所指的人或物距离说话人比较远。如：

这是一个橙子，那是一个苹果。
③从数上来看，this和that指单数， these和those指复数。如：

考前的心理准备，考前可通过心理暗示缓解紧张情绪，进行临场心理调节。紧张时可用“我能行”、“静心”、“认真”等自我暗示来稳定情绪，适当做做深呼吸。放松心情，减少压力，参加成考的学生需要将平时的家庭、学校、社会的压力全丢掉，轻装上阵。Coming back home in the evening, family and I sat and watched TV together, we are returning and eating the fruit while chatting, the whole family is happy and harmonious!考试要淡定。拿到试卷后，不要急于动笔，先浏览试题，粗略知道各题的难易、分值后合理安排答题时间。分值较小的题，如果一时做不出来，可先放一放，抢时间先做会做的题，然后再回头考虑本题。.I live very happily today! In the morning, it is very fine! Then I climb the mountain with family, the air on the mountain is very fresh, the flowers plants and trees on the mountain all seem extremely beautiful.
