Do the colleges allow you to participate in activities 29 will help you develop yourself intellectually and emotionally?
答案：(C) that
關係代名詞 that 引導形容詞子句修飾 activities，作子句主詞；what（本身已包含先行詞，不能再接先行詞使用）、they（代名詞，不是關係代名詞不能這樣連接子句）、those（指示代名詞，同樣不能這樣連接子句）都不合。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
四個選項有兩個是關係詞、兩個是代名詞，如果沒數清楚空格後面缺什麼，很容易挑到 they 或 those。
先看空格前面：activities ___ will help you develop yourself intellectually and emotionally。先行詞是 activities（活動），空格後面接的是 will help you ...——一個沒有主詞的動詞。既然缺主詞，就要一個能進去補位、同時又能把整串接到 activities 後面的字，那正是關係代名詞，填 that（也可以用 which）。這一格與 83 年第 17 題正好是一組對照，兩題把整條判準補完整了：83 年第 17 題的子句成分已滿（ordinary people used umbrellas），所以不能用關係代名詞、要用不占成分的關係副詞 where；本題的子句缺主詞，所以非關係代名詞不可。先數子句缺什麼，再決定用關係代名詞還是關係副詞。
what：本身已經含有先行詞（相當於 the thing which），前面不能再有 activities 這個先行詞。they：一般代名詞，不能把兩個子句接起來；填進去會變成 activities they will help you ...，兩個句子中間沒有連接詞。those：指示代名詞，同樣不能引導子句。
the activities that ...（……的那些活動）、the place where ...（……的地方）、participate in activities（參與活動）、develop oneself（充實自己）、intellectually and emotionally（在智識與情感上）、allow sb to V（讓某人……）。
