类别

形容词(短语)作状语

可以是单个形容词，也可以是形容词短语。若形容词短结构

语位于句子后面作状语，一般要用逗号将其和句子的其他部分分开；若单个形容词位于句子后面作状语，往往不需要用逗号

位置

通常位于句子主语之前或之后，有时位于句末

作用

4．with＋宾语＋宾语补足语

(教材原句P15) Diversity in a group means having animals with their genes arranged in different ways.

种群多样性是指种群中动物的基因以不同的方式排列。

[句法分析] (1)本句是简单句，动名词短语having animals...作means的宾语，with复合结构(即“with＋宾语＋宾语补足语”结构)作后置定语，their genes与arrange为动宾关系。

(2)with复合结构可作定语和状语，其具体形式如下：

不定式（表动作尚未发生）with＋名词/代词＋

现在分词（可表主动和进行）过去分词（可表被动和完成）即学即练

①With so much work to do，we can't waste any time.

有这么多工作要做，我们不能浪费时间。

②_____________________________，we found her house easily.

有这个男孩带路，我们很容易就找到了她的家。

③With the problem settled，we all felt happy. 问题解决了，我们都感到高兴。

[助记]

with复合结构用法口诀

with结构并不难，with后面宾语连，

动宾关系用过分，主谓关系用现分，

将来要把不定跟，还有三种形副介。

I. 用所给动词的适当形式填空。

5 形容词/副词/介词短语

①With all the books he needed________ (buy), the boy went home happily.

②He couldn't fall asleep with so many problems______(deal) with.

例句

The advantage is that if there is a new illness some of these animals may die, but others will survive and pass on the ability to resist that disease to the next generation.
