单元重点句型 1
1. As many f us already knw, having plans in place fr the future is n guarantee that they will becme reality. 正如我们许多人已经知道的那样，为未来制定计划并不能保证它们将成为现实。[句式分析] 语境中，as引导非限制性定语从句；主句中，动名词短语having plans in place fr the future充当主语，名词guarantee后接that引导的同位语从句，解释说明其具体内容。 [句型拓展] 同位语从句： 指的是在复合句中充当同位语的从句，属于名词性从句的范畴，同位语从句用来对其前面的抽象名词进行解释说明，被解释说明的词和同位语在逻辑上是主表关系。1. 可以跟同位语从句的名词通常有news，idea，fact，prmise，hpe，message，pssibility,等2. 英语中引导同位语从句的词通常有连词that，whether，连接代词what，wh。连接副词hw,when,where等。(注:if不能引导同位语从句。)

Thugh bth f the these men were ultimately successful, their paths t success were very different, their futures nt necessarily turning ut exactly as they planned. 虽然这两个人最终都取得了成功，但他们通往成功的道路却截然不同，他们的未来并不一定如他们所计划的那样。[句式分析] 语境中，thugh 引导让步状语从句，“their futures nt necessarily turning ut exactly as they planned”为“名词+现在分词turning ut”构成独立主格结构，其中 as they planned是as引导的方式状语从句。 [句型拓展] 独立主格结构: 由两部分组成，前一部分是名词或者代词，后一部分是非谓语动词(动名词、不定式、现在分词、过去分词)或形容词、副词、名词或介词短语。前后两部分具有逻辑主谓关系。

Whether big r small, what all ur chices have in cmmn is that they lead t specific cnsequences. 无论大小，我们所有的选择都有一个共同点，那就是它们都会导致特定的结果。 [句式分析] whether ... r...意为“不管...还是...”, 引导让步状语， what all ur chices have in cmmn 是what引导的主语从句， what 在从句中作宾语；that引导表语从句。 [句型拓展] 本语境，whether ... r...是N matter whether ... r...的省略形式。N matter + 特殊疑问词，引导让步状语从句，也可以使用特殊疑问词wh+ever来替代。
