动词和介词都带有宾语,很容易混淆,尤其有一些词如“在、到、给、跟、比”等常常兼有动词和介词两种性质。怎样在具体语境中判断它们是动词还是介词呢?可用以下几种方法:一是动词可以单独做谓语,而介词不能单独做谓语,只能构成介宾短语之后做谓语的连带成分。 Both verbs and prepositions are objects, and it is easy to confuse. In particular, some words such as “in, to, give, follow, ratio” often have both verbs and prepositions. How to judge whether they are verbs or prepositions in specific contexts? There are several methods that can be used: First, verbs can be used as predicates, and prepositions cannot be used as predicates alone, and can only constitute prepositional phrases after prepositional phrases.
