交技能，学校安排大量的课外活动，换句话说就是在教室里上完课后进行的活动。当决定接纳哪些学生时，老板和大学都寻找那些在多个领域有技能的学生。分数固然重要，课外活动也不容忽视。通过参加这些活动，学生们展示自己的特殊才能、领导能力和与他人的相处的能力。

　　Competitive sports⑲， for example, baseball, are probably the most popular of all the after­school activities. This is because⑳， for many American parents, it is important that\s\up1(21(21) their children , particularly\s\up1(22(22) boys, learn how to\s\up1(23(23) compete\s\up1(24(24) successfully. Young people are encouraged\s\up1(25(25) to take part in team sports such as football and basketball, since these games teach\s\up1(26(26) you to have the "winning spirit"\s\up1(27(27). For some students and their parents, high school sport is considered more important than academic\s\up1(28(28) achievements.

　　During the long summer holidays, it is a custom for American children to spend\s\up1(29(29) several weeks at summer camps. There are thousands of camps, and they can be found all over the country\s\up1(30(30). What these camps offer\s\up1(31(31) is an opportunity to\s\up1(32(32) take part in many different kinds of outdoor\s\up1(33(33) activities, for example, horse riding and water skiing\s\up1(34(34). Older teenagers are more likely to\s\up1(35(35) get summer jobs or go camping with a group of friends. Many go backpacking in the mountains of the west. 　　⑲competitive sports 竞技体育运动
