25R1 理解内容逻辑链为王。段意关联(考2段结合题) 7题 高亮题正确 作者思路:but后面是关键,正确答案是一定有but后面的内容的,而错误项迷惑你是改写了一些关键句,或者把关键句放在让步不重要的位置导致逻辑意思不对。
considerably (句子简化题 核心是找到一些隐含的逻辑)
TPO 25R1
托福阅读趋势:
单词句子为主的阅读理解能力速度偏慢了点:应用长难句的拆分和还原。因为后来我提炼出来有很多和主干无关的修饰可以扔掉。一大段只有几句的逻辑链
obliterate [ə'blɪtəreɪt]
vt.消灭;涂去;冲刷;忘掉
ejecta [ɪ'dʒektə]
n. 喷出物;排泄物
boulders
n. 岩石;[建] 大卵石(boulder的复数形式)
boulders: 岩石 | 井中软硬交替层 | 大卵石大卵石巨砾石底
41. liquefied ['lɪkwɪfaɪd]
v. 液化;溶解(liquefy的过去分词)
adj. 液化的

Another prominent feature of Mars’s surface is cratering. The Mariner spacecraft found that the surface of Mars, as well as that of its two moons, is pitted with impact craters formed by meteoroids falling in from space. As on our Moon, the smaller craters are often filled with surface matter-mostly dust-confirming that Mars is a dry desert world. However, Martian craters get filled in considerably faster than their lunar counterparts. On the Moon, ancient craters less than 100 meters across (corresponding to depths of about 20 meters) have been obliterated, primarily by meteoritic erosion. On Mars, there are relatively few craters less than 5 kilometers in diameter. The Martian atmosphere is an efficient erosive agent, with Martian winds transporting dust from place to place and erasing surface features much faster than meteoritic impacts alone can obliterate them.
According to paragraph 4, what is demonstrated by the fact that craters fill in much faster on Mars than on the Moon?(这个题干就是和erosion有关的)+() The Martian atmosphere is an efficient erosive agent, with Martian winds transpor(with独立主格 伴随)看红字winds transporting dust and erasing surface
AErosion from meteoritic impacts takes place more quickly on Mars than on the Moon.
BThere is more dust on Mars than on the Moon.
CThe surface of Mars is a dry desert.
DWind is a powerful eroding force on Mars. 这道题用时较长是因为看句子不清晰的原因
In paragraph 4, why does the author point out that Mars has few没有ancient craters that are less than 5 kilometers in diameter?(=Mars是腐蚀掉crater的地方,few没有小的就是因为小的被干掉了To support the claim)同上题- A
To explain why scientists believe that the surface matter filling Martian craters is mostly dust - B
To explain why scientists believe that the impact craters on Mars were created by meteoroids - C
To support the claim that the Martian atmosphere is an efficient erosive agent - D
To argue that Mars experienced fewer ancient impacts than the Moon did - 下一个题 修饰目的,这个句子是属于however后面的 和前面一句都是在对比火星和月亮坑的大小,他们的目的在最后一句风的作用导致坑(而非撞击) 干扰项是无关题目和前文非此段的信息

As on the Moon, the extent of large impact cratering (i.e. craters too big to have been filled in by erosion since they were formed) serves as an age indicator for the Martian surface. Age estimates ranging from four billion years for Mars’s southern highlands to a few hundred million years in the youngest volcanic areas were obtained in this way
what have scientists been able to determine from studies of large impact cratering on Mars?The age of Mars’s surface can vary from area to area. 同义改写的感觉
A comparison of the Copernicus crater on the Moon with the (fairly typical) crater Yuty on Mars demonstrates the differences. The ejecta surrounding the lunar crater is just what one would expect from an explosion ejecting a large volume of dust, soil, and boulders. However, the ejecta on Mars gives the distinct impression of a liquid that has splashed or flowed out of crater. Geologists think that this fluidized ejecta crater indicates that a layer of permafrost(D不是喷出物形成的 这个我觉得是考官给容易脑补的人设置的), or water ice, lies just a few meters under the surface. Explosive impacts heated and liquefied the ice, resulting in the fluid appearance of the ejecta.
According to paragraph 6, the ejecta of Mars’s crater Yuty differs from the ejecta of the Moon’s Copernicus crater in that the ejecta of the Yuty crater
AHas now become part of a permafrost layer
BContains a large volume of dust, soil and boulders
CSuggests that liquid once came out of the surface at the crater site
DWas thrown a comparatively long distance from the center of the crater

However, the ejecta ( surface feature)on Mars gives the distinct impression of a liquid that has splashed or flowed out of crater. Geologists think that this fluidized ejecta crater indicates that a layer of permafrost, or water ice, lies just a few meters under the surface. ( lie under Mars’s surface.)
我的插入题错了 其实下文是有对应的
This surface feature has led to speculation about what may lie under Mars’s surface.
According to paragraphs 1 and 2, which of the following is NOT true of 增多的趋势
