only United Kingdom Independence Party, sensing its chance, has sided with those pleading for a more considered approach to using green land.

請問to using green land，能否用to use green land.不定式形式？

an approach to sth.

approach 表示“辦法”； to 表示 “針對（做）某事（的辦法）”，是介詞，不是動詞不定式符號。所以， to 后接名詞、代詞或 doing。

Tosummarise,thisisacleverapproachtoacommonproblem.

總而言之，這是一個解決容易見到問題的巧妙辦法。
