【归纳拓展】现在分词作状语，应注意如下几点：(1)语法含义：表示意料之中的、自然而然的结果，现在分词前有时可加thus以示强调。(2)逻辑主语：句子的主语或现在分词前的整个句子。当现在分词的逻辑主语为前面的整个句子时，其作用相当于一个非限制性定语从句。
(3)时态特征：现在分词表示的动作发生在谓语动词所表示的动作之后，因此作结果状语的现在分词只用一般式。(4)语态特征：逻辑主语与构成现在分词的动词之间为逻辑上的主谓关系。(5)句中位置：通常位于句末，且常用逗号与前面的句子成分隔开。(6)扩展性：一般可转化为s that引导的结果状语从句。

3．(P27)Withut this prcess, Earth culd nt sustain life. 【翻译】没有这个过程，地球就不能维持生命。【句子剖析】本句中的“withut this prcess”是一个表示否定意义的介词短语，意为“要是没有这个过程”。它相当于一个条件状语从句。这个介词短语可放在句首，也可放在句末。
【归纳拓展】(1)nt…withut…意为“没有……就不能……”。这是一种双重否定句式，表示肯定意义。(2)withut所表示的条件如果是一种虚拟条件，则句子的谓语动词还应用虚拟语气。
(3)常见的双重否定结构还有：①never…withut…没有……不……；除……不……②cannt/can’t…t…越……越……；无论怎样……也不为过
Yu can’t praise him t highly. 你无论怎么表扬他都不为过。Yu can’t leave the cuntry withut a passprt. 没有护照你就不能离开这个国家。

【句式剖析】nt nly…but als…“不仅……而且……”，在本句中连接两个并列的现在分词，在句中作结果状语。
【归纳拓展】nt nly…but als…“不但……而且……”，连接两个并列的成分。(1)用于连接两个表示并列关系的成分，着重强调后者，其意为“不仅……而且……”；其中的als有时可以省略。
(2)若连接两个句子，且nt nly位于句首时，nt nly后面的句子要用部分倒装，将句子的助动词提前，放在主语的前面。(3)若连接的两个成分作主语，其谓语通常与靠近谓语的主语保持一致。
Nt nly yu but als he has t leave. Nt nly shuld we raise mney fr them but als we shuld help them rebuild their hme.

【归纳拓展】现在分词作状语，应注意如下几点：(1)语法含义：表示意料之中的、自然而然的结果，现在分词前有时可加thus以示强调。(2)逻辑主语：句子的主语或现在分词前的整个句子。当现在分词的逻辑主语为前面的整个句子时，其作用相当于一个非限制性定语从句。
(3)时态特征：现在分词表示的动作发生在谓语动词所表示的动作之后，因此作结果状语的现在分词只用一般式。(4)语态特征：逻辑主语与构成现在分词的动词之间为逻辑上的主谓关系。(5)句中位置：通常位于句末，且常用逗号与前面的句子成分隔开。(6)扩展性：一般可转化为s that引导的结果状语从句。

3．(P27)Withut this prcess, Earth culd nt sustain life. 【翻译】没有这个过程，地球就不能维持生命。【句子剖析】本句中的“withut this prcess”是一个表示否定意义的介词短语，意为“要是没有这个过程”。它相当于一个条件状语从句。这个介词短语可放在句首，也可放在句末。
【归纳拓展】(1)nt…withut…意为“没有……就不能……”。这是一种双重否定句式，表示肯定意义。(2)withut所表示的条件如果是一种虚拟条件，则句子的谓语动词还应用虚拟语气。
(3)常见的双重否定结构还有：①never…withut…没有……不……；除……不……②cannt/can’t…t…越……越……；无论怎样……也不为过

【句式剖析】nt nly…but als…“不仅……而且……”，在本句中连接两个并列的现在分词，在句中作结果状语。
【归纳拓展】nt nly…but als…“不但……而且……”，连接两个并列的成分。(1)用于连接两个表示并列关系的成分，着重强调后者，其意为“不仅……而且……”；其中的als有时可以省略。
(2)若连接两个句子，且nt nly位于句首时，nt nly后面的句子要用部分倒装，将句子的助动词提前，放在主语的前面。(3)若连接的两个成分作主语，其谓语通常与靠近谓语的主语保持一致。
