请教下托福TPO22阅读第三篇THE ALLENDE METEORITE
Chondrules and inclusions in Allende are held together by the chondrite matrix,a mixture of fine-grained,mostly silicate minerals that also includes grains of iron metal and iron sulfide.At one time it was thought that these matrix grains might be pristine nebular dust,the sort of stuff from which chondrules and inclusions were made.However,detailed studies of the chondrite matrix suggest that much of it,too,has been formed by condensation or melting in the nebula,although minute amounts of surviving interstellar dust are mixed with the processed materials..
9.According to paragraph 5,which of the following is indicated by studies of the mixture holding the inclusions together?
O Large amounts of this material were formed by condensation or melting in the nebula.
O This material contains more iron and iron sulfide than had previously been thought.
O This material is very similarto the material from which the refractory inclusions are made\x05
O The grains in this material are made from the same elements as chondrules ar
e这篇文章看的我有些晕.一下子就没看明白啥意思.求指教啊.题目就有点恍恍惚惚.主要个人语法很烂,我的问题是:
题目没怎么太看明白 :是说:下列哪一项是通过studies of the mixture显示了出来?holding the inclusions together怎么连着翻译好?感觉这题就是段落和选项都看明白了,题目没看懂,
A选项我知道是对的.那比如C选项呢?能不能说下?
再能不能比如具体分析下:However,detailed studies of the chondrite matrix suggest that much of it,too,has been formed by condensation or melting in the nebula…… 这个too是什么意思?

解读这段话的关键是理解 Matrix. 简单说,你可以把它想象成田字格.本段话要讨论 Allede的结构有两大块,第一是Chondrules类的物质;第二类是Inclusions, 比如铁之类的东西.
1. Allede = Chondrules + Inclusions
Chondrules > Chrondrite matrix > nebular dust= Chrondrules+inclusions.
Inclusions = iron metal and iron sulfide
2. chondrite matrix > much of has been formed by condensation or melting in the nebula, although minute amounts of
以上是基本结构.
这个题目已经属于 Make inference的考察内容,所以把握一些关键词对于解题更重要.
also, at one time . . ., however . . . Much of it, too, although minute. 可以作为推断和揣摩作者的口气词语.
总之,在遇到难词,生僻词的时候忽略不计,可以关注文章结构和作者语气为主.因为本题目需要考察你的inferential ability.
希望对你有帮助.

这里面的单词可能有很多生疏的,大概看上去好像有点理解困难,因为不和我们的生活相关,很多都是概念上的东西,但也有个好处就是这样的科普文逻辑性很强,你在练题目的时候要注意文章的逻辑连贯性。不懂的概念性的单词可以直接用单词大写代替。基本上这一段文字就在讲一个东西-就是chondrite matrix到底是由啥构成的。前面的介绍性文章只是帮助你理解。曾经有一个时间人们认为这个matrix 就是pristine nebular dust,而且同时chondrules and inclusions也是由这个dust组成的;后来,detailed studies of the chondrite matrix suggest that much of it, too, has been formed by condensation or melting in the nebula.这句话基本上搞清楚it指代的就是matrix就不影响理解了。这个too就是最普通的意思。这句话是说“后来研究表明大部分的matrix是通过condensation 或者是melting in nebula形成的”。
题目就是让你根据对mixture的研究找出下列选项哪一个是有在study中被表明的。就是让你根据题目找match的选项啦~holding the inclusions together 是个修饰,非限制性定语从句吧应该是,用来修饰前面的matrix的啦
