The survey 22 indicated that 45 percent of the school children read at least five books every month; __23__ 45 percent of them read less than three per month.
答案：(B) further
further 作副詞表示「進一步（指出）」，用來承接、補充調查的另一項發現；thus（因此，因果）、otherwise（否則）、for instance（例如）都不符合這裡「補充說明調查結果」的語意。
further 這個字，你的印象大概是「更遠的」（walk further）或當形容詞的「進一步的」，不太會想到它可以夾在主詞與動詞之間當副詞用，意思是「進一步地、還」。
答對率四成二。這是邏輯勾環，線索一定要跨句才看得到。前面已經列了好幾項調查結果：多少人覺得網路方便、多少人改看書、多少人沒用過網路、多少人不讀課外書、各類讀物各占多少。空格這一句 The survey ______ indicated that 45 percent of the school children read at least five books every month 是在同一份清單上再補一項。表示「再進一步、還指出」，用 further。填進去讀成 The survey further indicated that...（調查進一步指出……）。
thus（因此）要求後面是前面造成的結果，但新的一項數據並不是前面那些數據造成的；otherwise（否則）要求前面先有一個條件；for instance（舉例來說）要求後面是前面某個通則的例子，但這一句是新的一項發現，不是在為前面舉例。
further（進一步地，副詞）、furthermore（此外）、a further step（進一步的措施）、at least（至少）、indicate that ＋ 子句（指出、顯示）、per month（每個月）。
