How to Enrich Simple Sentences (1)
如何丰富简单句（之一）

Simple sentence does not mean that the sentence is simple in meaning; it means that the sentence contains a subject and a verb. Please identify the subject and the verb in the following sentence:

The bird flies.

(1) The subject is_________, and the verb is_______.

But the sentence above is too simple, it cannot fully convey the various thoughts the readers want to know. In actual writing the simple sentence has many modifiers(修饰语). With the modifiers you will have many expanded(扩展的) sentences. Now take a close look at how modifiers enrich the above simple sentence:

The bird flies to the South of China.
In winter, the bird flies to the South of China.
In winter, the bird with gray feathers flies to the South of China.

In winter, the bird with gray feathers flies to the South of China to enjoy the mild weather there.

In the first sentence an prepositional phrase (介词短语) "to the South of China" is added to the original sentence to indicate (表示) place; in the second sentence, another prepositional phrase "in winter" is added to indicate time; in the third sentence, a third prepositional phrase "with gray feathers" is added to indicate the characteristic（特征）of the bird；in the fourth sentence, an infinitive phrase (动词不定式) "to enjoy the mild weather there" is added to indicate purpose (目的) of the action (动作).

Exercise:

Please enrich the following sentence with the given phrases: on the boy's shoulder, with long white hair
The cat sits.
(2) _________________________________________________________.
