349.We don't have enough boxes _____.
A.to put these books B.to put these books in C.putting these books D.putting these books in
答
选A
答
B.to put these books in
因为还没有放进去，所以应该用不定式，强调放到里面，所以必须用in
答
B.to put these books in
“用来放书”,这是表目的
表目的的话,要用不定式做后置定语,排除CD
因为是put these books in （ the boxes ） ,所以in不能省略,选B
