    1.The boss required that all the related files and documents be prepared_______.

    A. by last Friday

    "by + 時間詞" 的意思是指在某一個特定時間前, 包含那個 by 後面的時間

    點. 和 "before + 時間詞" 比起來, before 的時間是之前不含那個時間點.

    by last Friday 是指 last Friday 前含 last Friday 當天喔

    before last Friday 是指 last Friday 前不含 last Friday 當天喔

    B. since last Friday

    since 常用在現在完成式的句子, 指的是 "自從..." 所以在這個地方並不適用.

    C. in last Friday

    這個選項本身就已經是錯的. 因為 last 前面不能再用 in ... every Friday, this

    Friday, 或是 next Friday 前面都不能再用任何 in 或 on.

    2. It has become clear that the world is slowly warming up,_____about 1 degree

    Fahrenheit over the past 100 years.

    基本上要知道為什麼選 A 前要先明白這個題目的意思是什麼 ... that the world

    is slowly warming up 是 "主詞"... 前面的 it 是虛主詞. 所以這句應該是..

    That the world is slowly warming up has become clear.

    意思是 ... 地球逐漸增溫也就溫室效應的這件事已經是變的很明顯...

    而後面的 by 是接著紙 warming up 的... by 是指 "藉著... / 用什麼方式...." 1 degree

    Fahrenheit 是 "華氏 1 度" 再加的 about 是指 "大約" 的意思. 所以整段 ...

    by about 1 degree Fahrenheit over the past 100 years 是說 ... 過去的 100年來以大約

    華氏 1 度的速度逐漸增溫.

    so.. by 應該是李者中唯一合適的喔

    for 比較偏向總共的意思.... 稍有不同... 雖然真的只有增加約1度囉

    I hope you find my answer great help..... thanks

    1. 因為by有"在...之前"的意思,所以整句話就是~老闆要求....再上禮拜五之前~

    B是指自從,意思不對..而C就更錯,因為禮拜幾的介係詞沒有用in的~

    2. 在這句by有"藉由"的意思,是藉著上升的溫度所以使前一句裡面說的"世界變暖", 故 用by~ for是只因為,由於,和這句意思不合~
