Since 2000, the day length has increased ＿＿（43）＿＿ about 1.33 milliseconds per century, up from 0.3-1.0 milliseconds in the 20th century. If greenhouse gas emissions continue unchecked, this rate could ＿＿（44）＿＿ 2.62 milliseconds per century by 2100.

重點空格43考介系詞用法：'increased by + 數量' 表示「增加了多少」，為固定片語。
秒殺技巧
increase by + 數字 = 增加了（差異量），為英文固定搭配。短文原句即為此用法，選A。
逐選項分析
A✓ 正確
短文原句為 'the day length has increased ___ about 1.33 milliseconds per century'，'increase by + 數量' 是固定片語，表示「增加了某個數量（差異值）」，完全符合語意。
B✕ 陷阱
'increase in' 後通常接名詞（如 an increase in temperature），不直接接數字量值；置入本句 'increased in about 1.33 milliseconds' 語法錯誤，不符英文慣用法。
C✕
'increase at' 後接速率或比率（如 increase at a rate of），本句後直接接數量值 '1.33 milliseconds'，若用 at 則需配合 'a rate of' 等結構，直接接數字不合語法慣例。
D✕
'increase of' 常見於名詞片語結構（如 an increase of 1.33 ms），但動詞 'increased' 後不直接接 'of + 數量'，語法上不正確，故不選。
