[lunkuo (藍藍)]

書名：網路練習題

題目：
     1. Today, 79 percent of the world's children, ________ six to eleven , are
        enrolled in elementary school.

(1) aged

(2) aging

(3) to age

疑問：為甚麼是1而不是2，因為who age =aging

2. For parents staying at home, the problem centers on what __________ to keep
   their kids entertained.

(1) does

(2) is doing

(3) can do

(4) can he done

答案是4，這題完全看不懂要考什麼，請各位老師指點，謝謝

推 amourmo     :第一題 who are aged 省略了are
→ amourmo     :第二題  4選項  為can be done 應是筆誤打成he
推 ntust661    :推~
→ noeoo       :第二題考被動用法。
