英文句子的文法疑問!

Question

Nearly 70 percent of the people are in favor of putting the government's arms procurement package from the United States 【to screening】 in the Legislative Yuan, Liu Chih-chien, a Ministry of National Defense spokesman said.
請問一下在上面的句子當中, to後面的 screen為何要加【ing】呢??

Answer 1

這裡的to是介係詞,所以後面的動詞要加ing,這個to的來源是 put N1 to N2 這個片語來的(to後面要接名詞或動詞名詞)put .... to screening 意即有將軍購案交付審核的意思
