有时,在句子主语之前或之后会出现一个介词短语来修饰说明句子主语,这些修饰语被看作是句子主语的一部分,但却不影响句子中的动词形式。句中的动词只与主语本身保持一致。主语修饰语经常有下列介词短语:1.with...One man with his wife,looking very anxious,was asking the guard tolet them through.有个男人带着他的妻子,看上去很焦虑,正在恳求那位看守放行。 Occasionally, a prepositional phrase appears before or after the subject of a sentence to modify the description of the subject of the sentence. These modifiers are treated as part of the subject of the sentence without affecting the verb form in the sentence. The verb in the sentence is only consistent with the subject itself. Subject modifiers often have the following prepositional phrases: 1.with ... One man with his wife, looking very anxious, was asking the guard tolet them through. A man with his wife looks anxious and is begging A caretaker release.
