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.

1．And my memory became so large that
even I couldn't believe it! 我的存儲量變得如此巨大，甚至連我自己都不能相信！
so...that... 如此……以致……。 that 引導結果狀語從句。另外， such...that...也引導結果狀語從句。其結構形式為：
so＋adj./adv.
＋adj.＋a/an＋可數名詞單數
＋many/few＋可數名詞復數
much/little＋不可數名詞that 從句
such＋a/an＋adj.＋可數名詞單數
＋adj.＋可數名詞復數
＋adj.＋不可數名詞that 從句

拓展：(1)當 so.../such...位于句首時，句子要部分倒裝。

詞，在 so that前可以有逗號，意思是“因此；所以”。

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

of high quality在句中做定語，屬于of＋n.結構。這一結構相當于形容詞，在句中可以做表語、定語或賓語補足語。
(1)of＋n.結構中的名詞是抽象名詞時，相當于其名詞所對應的形容詞的意思，說明被修飾詞具有某種特征或屬性。常用的名詞有：use, importance, help, value, interest, benefit 等。這些名詞前可用 great, no, little, some, any, not much 等修飾，以表示不同程度。
