46、_to other natural changes.(P26)但是，同自然界的其他变化相比，这种升高是迅速的。这是一个省略句，补全之后是.but it is a rapid increase when it is compared to other natural changes。一般说来，省略现象多出现在下列五种状语从句中：(1)由 when，while，as，before，after， till，until，once等引导的时间状语从句；(2)由whether，if，unless 等引导的条件状语从句；(3)由 though，although，even if，whatever等引导的让步状
47、语从句；(4)由 as，than 等引导的比较状语从句；(5)由as，as if，as though 等引导的方式状语从句。上述状语从句在省略时，并非任何成分都可以省略，而是遵循以下原则：(1)当状语从句的主语与主句的主语一致时，可以省略状语从句的主语和系动词be，这时从句中可出现如下结构：连词(as，as if，once)名词。如：Once(he was)a worker，Pang Long now becomes a famous singer.庞龙曾经是个工人，现在成了一位著名的歌手。 连词(though，whether，when)形容词。如：Work hard when(you are

50、的主语是it，谓语动词中又含有系动词be 时，可以把it和系动词be一起省略。此时构成连词(if，unless，when，whenever)形容词的结构。如：Unless(it is)necessary，youd better not refer to the dictionary.如果没有必要，你最好不要查字典。2There_is_no_doubt_that the earth is becoming warmer.(P26)毫无疑问地球正在变暖在There is no doubt后常可跟that引导的同位语从句(在肯定句中，doubt后面有时可跟whether引导的从句)。There is
51、 no doubt that you will succeed if you try your best.毫无疑问如果你尽最大努力你一定会成功。There is no doubt that he will come on time.他一定会准时来。类似常用结构：There is no knowing/telling.没法知道/说There is no need.没有必要There is no question.是没有问题的。There is no reason.没有理由There is no possibility that.是没有可能的。It is no/small wonder that.(No wonder that).难怪It is a wonder that.真奇怪/真是令人惊奇。Step 6Homework1Finish off the Workbook exercises.
