Pat Mitchell: That day, January 8, 2011, began like all others. You were both doing the work that you love. You were meeting with constituents, which is something that you loved doing as a congresswoman, and Mark, you were happily preparing for your next space shuttle. And suddenly, everything that you had planned or expected in your lives was irrevocably changed forever.

Mark Kelly: Yeah, it's amazing, it's amazing how everything can change for any of us in an instant.People don't realize that. I certainly didn't. Gabby Giffords: Yes. MK: And on that Saturday morning, I got this horrible phone call from Gabby's chief of staff. She didn't have much other information. She just said, "Gabby was shot." A few minutes later, I called her back and I actually thought for a second, well, maybe I just imagined getting this phone call. I called her back, and that's when she told me that Gabby had been shot in the head. And from that point on, I knew that our lives were going to be a lot different.

PM: And when you arrived at the hospital, what was the prognosis that they gave you about Gabby's condition and what recovery, if any, you could expect?

MK: Well, for a gunshot wound to the head and a traumatic brain injury, they typically can't tell you much. Every injury is different. It's not predictable like often a stroke ...
出国留学网托福考试栏目为您带来“托福阅读之定语从句与后置分词”，备考中的朋友赶快跟着小编一起来看看吧!
1.定语从句
托福阅读读完主句主语后，如果发现有定语从句的引导词that，which，who等，一定要跳过第一个或并列的几个带有时态的动词(定语从句的谓语动词)，直接寻找第二个带有或并列的几个带有时态的动词(主语的谓语动词)，并将从定语从句的引导词至第二个带有时态的动词之间的部分用括号括起来，括号中的这部分就是修饰主语主语的定语从句。这类句子的阅读解步骤与前面提到的托福阅读文章中的两类句子基本一致。
例子：
The Ediacara fossil formation, which contains the oldest known animal fossils, consists exclusively of soft-bodied forms.
分析：主语The Ediacara fossil formation，which contains the oldest known animal fossils非现在性定语从句作插入，谓语consists exclusively of ，宾语soft-bodied forms。
定语从句先不读，读完句子主干之后再读。
下面我们按照上述步骤来理解这句话。
①读句子主干：主语(The Ediacara fossil formation)→谓语(consists exclusively of)→宾语(soft-bodied forms)
翻译：E化石形势只包含了软体动物，
②读主语的定语从句：which contains the oldest known animal fossils
翻译：包含了已知的最古老的动物化石
整个句子的意思就是：E化石形成，它包含了已知的最古老的动物化石，只包含了软体动物。
2.后置分词
有些长难句中，主语和谓语之间夹杂着一个修饰主语的后置分词结构，包括现在分词结构和过去分词结构两种。后置的现在分词结构比较容易辨识，在阅读句子时，可以将现在分词与谓语动词之间的部分用括号括起来，先读句子的主干，再读括号中的部分。后置的过去分词结构是个难题，不少人容易将过去分词错当成主句谓语动词的过去式。为了避免这种错误，在读长难句的时候需要分析主语与动词之间是主动关系还是被动关系。如果主语与动词之间是被动关系，而该动词前面没有表示被动关系的be动词，那么这个词就是主语的后置过去分词，而不是句子的谓语。将这部分用括号括起来即可，对于托福阅读试题解答就很有帮助了。读句子步骤如上。
Petroleum, consisting of crude oil and natural gas, seems to originate from organic matter in marine sediment.
分析：主语Petroleum，consisting of crude oil and natural gas后置定语做插入，seems to originate from谓语， organic ...
