哪位高手帮我分析一下这几个句子分别的句子成分~~~~!!感激!!

1.The structure of the backbone shows, however,that Ambulocetus swam like a modern whales by moving the rear portion of its body up and down,even though a fluke was missing.
个人认为:The structure of the backbone 是主语 shows是谓语 ,that后面是宾语从句,however是插入语。但是感觉宾从是不是太长了.....是不是还可以再进行分析?

2.He refused to develop projection technology,reasoning that if he made and sold projectors,then exhibitors would purchase only machine-a projector-from him instead of several.
只知道He是主语,refused to develop 是谓语,projection是宾语。从reasoning that开始后面的就不知道要怎么分析了,另外 refused to develop 又是什么成分,是不定式吗?
小女现在在准备托福考试,但是从小语法学得不好,都是考完试就忘记的,现在发现很多长难句理解不透。当然上面两句还是比较好理解,但是就是不知道应该怎么分析成分,希望各位大侠指点指点,另外可以说说考托福和sat要具备哪些语法知识吗~~??感激不尽!!!

1.The structure of the backbone shows, however,that Ambulocetus swam like a modern whales by moving the rear portion of its body up and down,even though a fluke was missing.
译文:
然而,从走鲸的脊骨结构看,就算少了一个尾片,通过身体尾部的上下运动,它们也能像现代鲸鱼那样游动。

您对主句的分析是正确的。在宾语从句中,Ambulocetus是主语,swam是谓语,like a modern whales是swam的一个状语,by moving…and down是swam的另一个状语,even though…是swam的让步状语从句。

2.He refused to develop projection technology,reasoning that if he made and sold projectors,then exhibitors would purchase only machine-a projector-from him instead of several.
译文:
他不愿开发投影技术,他认为如果研制出投影机并投放市场销售,那么放映商从他那儿买的只是机器——一台投影机,不会买多台。
成分分析:He是主语,refused to develop 是谓语,projection technology是宾语,reasoning that……是伴随状语从句,表明reasoning这个动作伴随refused to develop发生,其逻辑主语是He。在该状语从句中,that后if……是条件状语,then后是该状语从句的主句。

托福改革后,没有单独的语法测试。SAT的语法考查是一般性考查,不会偏颇,国内的语法教学足以应付。

1 that 后面是宾语从句 by moving the rear portion of its body up and down 是做方式状语
even though a fluke was missing 是让步状语从句
2 reasoning that 后面是if 引导的条件状语从句,如果他made and sold projectors 那么exhibitors 就会 purchase only machine-a projector-from him instead of several。
reasoning that 引导的是 原因状语从句
refused to develop projection technology 是主句,“拒绝发展工程科技”的意思
对于托福 这类考试,阅读难,但主要是找主句,从句有的不太懂 也没什么事,但最好能把那些从句都搞熟了,不过也没必要分的很细,你的这些分析差不多可以了,能够理解句子大概意思就能做好题了。所以主要的是从句知识要弄清,还有词汇啦~~呵呵 加油吧!

1.楼主前面的分析都对,that后的确是宾语从句,从句里还有一个让步状语从句。even though:即使
2.refuse to do是拒绝做某事,to to这里是做宾语的,后面是现在分词做伴随状语,then后面就是并列句了。本回答被提问者采纳
