Green Action in Our Class
April 12th is memorable because our class had a meaningful experience on that day. In the morning, we bicycled to the suburbs to plant trees, talking and laughing all the way. Upon arrival, we began to work immediately. Some were digging holes. Some were carrying and planting trees. Others were watering them. After getting the work done, we put up a board reminding people to protect the trees. Before leaving we took some photos to record our green action. Seeing the lines of trees, we all had a sense of achievement. We all think it's our duty to protect and beautify our environment.

even I couldn't believe it! 我的存储量变得如此巨大，甚至连我自己都不能相信！
so...that... 如此……以致……。 that 引导结果状语从句。另外， such...that...也引导结果状语从句。其结构形式为：
so＋adj./adv.
＋adj.＋a/an＋可数名词单数
＋many/few＋可数名词复数
much/little＋不可数名词that 从句
such＋a/an＋adj.＋可数名词单数
＋adj.＋可数名词复数
＋adj.＋不可数名词that 从句

拓展：(1)当 so.../such...位于句首时，句子要部分倒装。

词，在 so that前可以有逗号，意思是“因此；所以”。

2．Anyhow, my goal is to provide humans with a life of high quality.

of high quality在句中做定语，属于of＋n.结构。这一结构相当于形容词，在句中可以做表语、定语或宾语补足语。
(1)of＋n.结构中的名词是抽象名词时，相当于其名词所对应的形容词的意思，说明被修饰词具有某种特征或属性。常用的名词有：use, importance, help, value, interest, benefit 等。这些名词前可用 great, no, little, some, any, not much 等修饰，以表示不同程度。
