第一单元第一课生活方式
我是一名……积极进取的人！
我是李颖。
我喜欢为自己设定目标。
我是一名积极进取的人——当我打算做一件事时，我会尽全力去实现。
高中是一个新的开始。
学习当然是我生活中的一个重要部分。
我倾向在学期开始时为每个科目设定一个目标。
这个学期，我的目标是把每一门学科都学好。
生物学是我最喜欢的学科，我的目标是为获得大学生物学学位做准备。
我总是在所有课上专心听讲积极思考，这样放学后我就有更多可支配的时间做我感兴趣的事。
我喜欢读各种各样的书。
我有一份阅读清单，并经常更新这份清单。
同时，我也是学校长跑队和志愿者俱乐部的积极成员。
全力以赴，一起实现团队目标，总是让我兴奋不已。
为了实现我想要的一切，我必须好好利用时间。
在学校，我利用空闲时间做作业。
放学后，我尽可能利用所有时间温习白天所学。
例如，坐公交车回家通常需要20分钟。
我经常利用这个时间复习英语单词。
常言道：“分秒必争！”
设定目标并取得进步！

• 火星的大气密度只有地球的大约1%，非常干燥， 温度低，表面平均温度零下55℃，水和二氧化 碳易冻结。在火星的早期，它与地球十分相似。 像地球一样，火星上几乎所有的二氧化碳都被 转化为含碳的岩石。但由于缺少地球的板块运 动，火星无法使二氧化碳再次循环火星地形表 面到它的大气中，从而无法产生意义重大的温 室效应。因此，即使把它拉到与地球距太阳同 等距离的位置，火星表面的温度仍比地球上的 冷得多，没有水，也没有空气，也没有树。
