问题 We all agree that computers are essential ______ the problems of increasing population.

选项 A、to solve
B、to solving
C、solving
D、of solving

答案B

解析此题考点为形容词与介词搭配。essential必要的，基本的，本质的。essential to译为“对…是必不可少的”，这里“to”是介词，后接动名词，所以B是正确答案。题干中that从句可以同义转换为下列句子：It is essential for computers to solve problem of increasing population．句中用不等式to solve．．．与for computers构成实际主语。本句意为：我们一致同意，电脑是解决日益增长人口的问题必不可少的工具。
