4.Which of the following can be inferred from paragraph 3 about the solid gypsum layer?
○It did not contain any marine fossil.
○It had formed in open-ocean conditions. (原文中:Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert flats.已经明确说明formed on desert flats。 这个选项与原文直接矛盾,所以错误。)
○It had once been soft, deep-sea mud.(没有提及的)
○It contained sediment from nearby deserts.
Sediment above and below the gypsum layer contained tiny marine fossils, indicating open-ocean conditions.
我选的D。不知道这题的pepple,sediment gypsum layer之间有什么复杂关系
(正确答案A,我看到这句话
Sediment above and below the gypsum layer contained tiny marine fossils, indicating open-ocean conditions.就直接排除了)
第十题
As a result of crustal adjustments and faulting, the Strait of Gibraltar, where the Mediterranean now connects to the Atlantic, opened, and water cascaded spectacularly back into the Mediterranean.
10. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
○The strait of Gibraltar reopened when the Mediterranean and the Atlantic became connected and the cascades of water from one sea to the other caused crustal adjustments and faulting.
○The Mediterranean was dramatically refilled by water from the Atlantic when crustal adjustments and faulting opened the Strait of Gibraltar, the place where the two seas are joined.
○The cascades of water from the Atlantic to the Mediterranean were not as spectacular as the crustal adjustments and faulting that occurred when the Strait of Gibraltar was connected to those seas.
○As a result of crustal adjustments and faulting and the creation of the Strait of Gibraltar, the Atlantic and Mediterranean were connected and became a single sea with spectacular cascades of water between them.
An expedition to the Mediterranean answered some long-standing questions about the ocean’s history.

Answer choices
1. The Glomar Challenger expedition investigated changes in invertebrate fauna and some unusual geologic features.
2. Researchers collected fossils to determine which new species migrated from the Atlantic with older species.
3. Scientists aboard the Glomar Challenger were the first to discover the existence of domelike masses underneath the seafloor.
4. Samples recovered from the expedition revealed important differences in chemical composition and fossil distribution among the sediment layers.
5. Evidence collected by the Glomar Challenger supports geologists' beliefs that the Mediterranean had evaporated and become a desert, before it refilled with water.
6. Mediterranean salt domes formed after crustal movements opened the straits between the Mediterranean and the Atlantic, and the Mediterranean refilled with water.
