[請益] TPO閱測 Meteorite Impact and Dinosaur Extinction
懇請指教 平時閱測不會錯這麼多 這篇大暴走
檢討剩兩題百思不得其解 懇請幫忙
Paragraph 2: If an impact is large enough, it can disturb the environment of
the entire Earth and cause an ecological catastrophe. The best-documented
such impact took place 65 million years ago at the end of the Cretaceous
period of geological history. This break in Earth's history is marked by a
mass extinction, when as many as half the species on the planet became
extinct. While there are a dozen or more mass extinctions in the geological
record, the Cretaceous mass extinction has always intrigued paleontologists
because it marks the end of the age of the dinosaurs. For tens of millions of
years, those great creatures had flourished. Then, suddenly, they disappeared.
2. In paragraph 2, why does the author include the information that dinosaurs
had flourished for tens of millions of years and then suddenly disappeared?
○To support the claim that the mass extinction at the end of the Cretaceous
is the best-documented of the dozen or so mass extinctions in the geological
record
○To explain why as many as half of the species on Earth at the time are
believed to have become extinct at the end of the Cretaceous
○To explain why paleontologists have always been intrigued by the mass
extinction at the end of the Cretaceous
○To provide evidence that an impact can be large enough to disturb the
environment of the entire planet and cause an ecological disaster
我選4，為什麼4不行? (答案為3)
---------------------------------------------------------------------------
Paragraph 6: Impacts by meteorites represent one mechanism that could cause
global catastrophes and seriously influence the evolution of life all over
the planet. █According to some estimates, the majority of all extinctions of
species may be due to such impacts. █Such a perspective fundamentally
changes our view of biological evolution. █The standard criterion for the
survival of a species is its success in competing with other species and
adapting to slowly changing environments. █Yet an equally important
criterion is the ability of a species to survive random global ecological
catastrophes due to impacts.
13. Look at the four squares [█] that indicate where the following sentence
can be added to the passage.
This is the criterion emphasized by Darwin's theory of evolution by natural
selection.
Where would the sentence best fit?
為什麼答案是3? 我選4。 因為空格4前面有提到criterion，放在空格4
"This is the criterion...." 感覺比較不突兀
感謝幫忙 謝謝!
