托福阅读否定事实信息题是阅读考试十大题型之一，通常每篇阅读中都会出现;tpo是托福阅读备考最权威的材料，所以托福小编综合二者，为大家集中整理了tpo阅读中考察的否定事实信息题及其对应的解析，供大家参考使用。本文带来的是TPO5-3的否定事实信息题，一起来看看吧。
TPO5-3 The Cambrian Explosion
Paragraph2
One interpretation regarding the absence of fossils during this important 100-million-year period is that early animals were soft bodied and simply did not fossilize. ■ Fossilization of soft-bodied animals is less likely than fossilization of hard-bodied animals, but it does occur. ■ Conditions that promote fossilization of soft-bodied animals include very rapid covering by sediments that create an environment that discourages decomposition.■ In fact, fossil beds containing soft-bodied animals have been known for many years. ■
5.According to Paragraph2, which of the following is NOT a question that paleontologists asked about the Cambrian explosion?
¡Why was the origin of life a simple step in Earth’s history?
¡Why did it take so long for multicellular organisms to develop?
¡Why did animal life evolve so rapidly?
¡Why does the fossil record lack evidence of animal evolution during that time?
解析EXCEPT题，排除法。A的simple step做关键词定位至第三句，但这句话不是一个问题，所以A错，选;B选项的so long对应原文第二句的so late，所以正确，不选，注意不要单纯以multicellular organism做关键词，会导致定位错误;C对应倒数第二句，正确，不选;D的lack evidence对应原文倒数第三句的not document，正确，不选
[2]一个多世纪以来，科学家们对这次大爆发一直有疑惑。为什么它发生的得这么晚?多细胞生物的出现相对于生命的出现而言则是一次相对简单的进化。为什么化石没有记录下动物演化的一系列变化呢?为什么动物生命进化得如此迅速呢?古生物学家们仍旧在研究化石记录以期回答这些问题。
Paragraph4:
A slightly younger fossil formation containing animal remains is the Tommotian formation, named after a locale in Russia. It dates to the very early Cambrian period, and it also contains only soft-bodied forms. At one time, the animals present in these fossil beds were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms that arose in the early Cambrian period and disappeared before the end of the period, leaving no descendants in modern animal groups.
8.Which of the following is NOT mentioned in Paragraph4 as being true of the Ediacara formation?
¡It contains fossils that date back to the Precambrian period.
¡It contains only soft-bodied animal fossils.
¡It is located on a single site in Australia.
¡It does not contain any fossils of the ancestors of modern animals.
解析EXCEPT题，排除法。A的Precambrian对应第二句，正确，不选;B的soft-bodied animals对应第一句的后半句，正确，不选;注意exclusively就是only之意;C的相关信息来自第二句，但第二句说的是worldwide in distribution，不是只在澳大利亚有，所以C说反了，选;D的modern animals对应最后一句，正确;不选
[4]含有最古老的动物化石的伊迪卡拉化石群就全部由软体动物化石组成。尽管伊迪卡拉是以澳大利亚的一处地名而命名，但是伊迪卡拉沉积层的分布却遍及世界各地，并且可以追溯到前寒武纪时期。这些7亿年前形成的地层为现代动物的起源提供了一些新的线索。因为古生物学家们认为它代表着一次失败的进化试验，其中并没有包含任何现代动物的祖先。
以上就是托福阅读TPO5-3中的否定事实信息题及其解析，大家可以在备考的时候参考复习，希望能够帮助大家的考前准备。最后前程百利祝大家都能取得理想的托福考试成绩。
