Unit 3 Under the sea
Using Language
A NEW DIMENSION OF LIFE
崭新的生活空间 1月19日我坐在温暖的夜空下，手里拿着一瓶冷饮，回忆着当天的事情——这是神奇的一天！这天上午，我戴着呼吸器在近海的珊瑚礁上潜泳，这是我从来没有过的绝妙经历。看到这样奇特的美景，我周身的每个细胞都苏醒了，就像发现了一个全新的生活空间似的。 我首先注意到的是我周围那些鲜艳的色彩——紫色、红色、橘黄、明黄、蓝色和绿色。那些珊瑚都是稀奇古怪的——有的形状像扇子、盘子、脑袋和彩条，有的像香菇、树枝和鹿角。还有种类繁多、小巧整齐、姿态优雅的鱼穿行在珊瑚丛中，或环游于珊瑚的四周。 我在那些鱼群中游泳，他们似乎并不在乎。我特别喜欢那些橘黄和白色相间的小鱼，他们藏在波动着的细长的海藻里。我也喜欢那些为大鱼清洁身体的小鱼——我甚至还看到这些小鱼游进大鱼的嘴里去帮他们刷牙。当我用水下探明灯探索小石洞、岩石和狭窄通道的时候，似乎每个角落都有使我感到惊奇的东西等着我：黄绿相间的鹦嘴鱼倒挂着，用它那像鸟一样的硬嘴从珊瑚上吸吮微小植物；带着黄斑点的红色海蛞蝓从一个蓝色的海星旁边滑行过去；一只长相聪慧的大乌龟紧贴着我的身旁而过，我几乎可以摸到它了。
Unit 4 一封家信
亲爱的罗斯玛丽:
谢谢你的来信，收到你的信真是太高兴了。我知道你急于了解我在这儿的生活情况。我在信中附有几张照片，能够帮助你想象出我所谈到的地方。
你问起我中学情况。它是一所丛林学校——教室是用竹子搭起来的，屋顶是用茅草盖的。我只要步行几分钟就到学校了。每次我走到学校操场的时候，迎接我的是男孩子们一片“早上好”的声音。他们中许多人走了很长的路，有时候要走两个小时才能到学校。
这儿没有电，也没有水，甚至连课本也没有。我还在努力适应这儿的条件。但是有一点是肯定的，我在教学中更富有想象力了。理科对我来说是最富挑战性的课，因为没有设备。如果需要水，我还得从家里用水桶提过来～有一天，我正给孩子们做化学实验的演示，我还没有明白怎么回事，混合剂就到处冒气泡了～孩子们从来没有见过这种情况，吓的都往窗外跳去。有时候我真想知道，化学对这些孩子究竟有多大的用处。他们中的大多数学完八年级以后就要回到他们的村庄去了。说实在的，我真的不知道我教的课是否让这些孩子的生活有所改变。
相对于高一，高二课程的难度提高了不少，知识容量大增。只有扎实掌握这部分知识才能较为轻松地完成高三总复习。这就对同学们高二期间的英语学习提出了更高要求。以下是我给大家整理的高二英语选修七第三单元知识点，希望大家能够喜欢!
