定语从句长难句分析方法有哪些

定语从句长难句分析方法：

A.准确判断定语从句所修饰的对象

由于定语从句与其所修饰的对象之间常有分割成分，而该分割成分中与定语从句紧挨着的名词常常会被误认为是定语从句的先行词。因此遇到这种结构一定要根据上下文和常识进行判断。

We may define chemistry as the science in which we deal with the chemical change in matter as a result of which it is possible to form a new substance.

本句有两个由which引导的定语从句：第一个定语从句修饰的对象是science而不是chemistry;第二个定语从句修饰的对象是chemical change 而不是result或matter

译文:我们客户可以说，化学式论述物质的化学变化的科学，通过这种变化可能得到一种新物质。

B.要注意区分从句的层次

定语从句是最可能出现嵌套结构的。一句话中往往包括好几个定语从句，这些从句有时是相互并列的.关系，有时是嵌套关系。分析句子的时候应注意区分。

The child who is raised in an environment where there are many stimuli which develop his or her capacity for appropriate responses will experience greatly intellectual development.

本句主语和谓语之间有三个定语从句，第一层是who is raised in an environmen，修饰的是the child ;第二层是where there are many stimuli ，修饰的是environment；第三层是which develop his or her capacity for appropriate responses ，修饰的是stimuli 。三个层次一层套一层。

2. If they can each be trusted to take such responsibilities, and to exercise such initiative as falls within their sphere, then administrative overhead will be low.

如果他们每个人都能予以信任承担这样的职责，并在他们所管辖的范围内发挥主动性，那么管理费用就会降低。

3. There are probably no question we can think up that cant be answered, sooner or later, including even that matter of consciousness.

4. The curtain was rung down in that phase of history, at least, by the sudden invention of the hydrogen bomb, of the ballistic missile and of rockets that can be aimed to hit the moon.
