(答案→)taken good care of
解析：
【小题1】taken good care of 本句是take care of的被动语态形式，of是不能省略的。
【小题2】去掉into enter是及物动词，后面直接加宾语，不要介词。
【小题3】in which 或 where 本题是定语从句，后面的句子结构很完整，所以使用关系副词。
【小题4】 regularly 改为 regular 用形容词修饰名词basis。
【小题5】 去掉to marry是及物动词，后面直接加宾语，不需要使用介词to。
【小题6】 去掉 to deserve是及物动词，后面接动名词或者to be done。
【小题7】 being built 本句的时间状语now说明使用现在进行时，本句是被动语态。
【小题8】so clever clever是形容词，前面要so修饰，such后面接名词。
【小题9】passers-by 该复合名词的复数形式，是主体名词后加s。
【小题10】have been used 或在1970s前加the(改对一处就可给分) 本句是一个被动语态的形式。The 1970s指在20世纪70年代。
