look可以是及物动词，后接不定式作宾语。以下为《韦氏高阶》对此的释义和例句：

[+ object]

a : to want or try to do something — followed by to + verb

• a company looking to become a leader in the industry

• We're looking to create something new.

b : to expect something — followed by to + verb

• We look to have a good year. = We are looking to have a good year.

网友的句子中，look to dig up...为上述释义a的用法。即=try to dig up sth的意思。
