The ancient Egyptians believed firmly in life 16 death.
答案：(C) after
語意「堅信死後有生命」（life after death＝死後的生命/來世），after（之後）符合這個固定概念；for／by／into 都不合。
after 在你腦中的第一個意思是時間上的「在…之後」，很少想到 life after death 是一個完整的說法，指的就是「來世、死後的生命」。這一格最容易錯在把中文語序搬過來：中文說「死後的生命」，死在前面；英文寫成 life after death，life 反而在前面。
先確定空格前後是什麼。believe in 後面接的是一個名詞組，所以 life ______ death 整包是名詞，空格是把兩個名詞接起來的介系詞。接著往下讀。下一句說 When a person died, his or her soul was thought to travel to an underworld（人死後靈魂會前往冥界），再往下 progress to a better life in the next world（前往來世過更好的生活）。文章講的順序是先死亡、之後還有生命，所以是時間上的先後：death 在後、life 在前，中間用 after。整句是「古埃及人堅信人死後仍有來生」。
for：表目的或對象，life for death 講不通。by：表方式或經手者，life by death 也不成話。into：表進入或轉變，change into 才是變成；life into death 沒有這種說法，而且方向與文章相反——文章講的是死後仍有生命，不是生命變成死亡。
life after death（來世、死後的生命）、believe in（相信…的存在、信仰）、the next world（來世）、an underworld（冥界）、be closely related to（與…密切相關）、when it comes to（一談到…）。
When it comes to Egypt, people think of pyramids and mummies, both of which are closely related to Egyptian religious beliefs. The ancient Egyptians believed firmly in life 16 death. When a person died, his or her soul was thought to travel to an underworld, where it 17 a series of judgments before it could progress to a better life in the next world.
For the soul to travel smoothly, the body had to 18 unharmed. Thus, they learned how to preserve the body by drying it out, oiling and then 19 the body in linen, before placing it in the coffin.
Egyptians also built pyramids as 20 for their kings, or pharaohs. The pyramid housed the pharaoh's body together with priceless treasure, which would accompany him into the next world.
