Answer 1

18. C
on/upon doing sth 一...(就...)
19. D
used to可用两种否定：usedn't或didn't
20. D
that引导同位语从句,解释proof的具体内容；且that在该从句中不充当任何成分,只起引导作用
21. D
从句意上看,是“习惯于”即：be used to doing sth；又是被动语态,即“被批评”,所以结合成：be used to being done
22. C
否定词never提前到句首,则该句采用部分倒装；从时间状语before看,用现在完成时最好.
原句正常句序：Man has never been so highly successful in changing his surroundings.
23. A
状语从句的省略: while watching television=while he was watching television
24. C
句子主语是the city,它和动词see是被动的关系,“城市从直升机上被看”,所以用过去分词短语做状语表被动关系
25. B
含否定词not until的短语提前只句首,该句采用部分倒装；时间状语many years later表明本句是一般过去时,所以把did提前
本句正常句序是：The whole truth didn't become known until many years later.
