例题1
2014年5月SAT真题阅读解析(Section Questions 12)
……..
Spartans, Corinthians, Athenians; and non-Greek
interlocutors from farther off as well: Egyptians of course,
40 but also Arabians, Ethiopians, and many others. On his
extensive travels Herodotus talked with a wide variety of
people; in most instances we can only guess where he
spoke to them, what problems he might have had in
communicating cross-culturally or through an interpreter,
45 and how accurately he remembered or transcribed what
they told him. What he repeatedly emphasizes is that his
stories contain real information, but he remains aware, and
wants us to be aware too, of the fact that as data they are
only as good as the quality of his sources allows.
12. Lines 42-46 ("in most... told him”) primarily serve to
(A) emphasize uncertainties about Herodotus‘ gathering of information
(B) justify the skeptical attitude some scholars take toward Herodotus’ work
(C) explain why Herodotus was dubious about some of his sources' claims
(D) advance the idea that Herodotus may have invented some of his information
(E) refute the suggestion that Herodotus did not actually interview anyone
答案：A
考点：推断题
解析：42-46行中的("in most... told him”)主要是为了?
(A) 强调Herodotus收集信息的不确定性
(B) 证明某些学者对Herodotus作品怀疑的正确
(C) 解释为什么Herodotus会对某些信息来源产生怀疑
(D) 提出自己的观点认为Herodotus有可能自己编撰了一些信息
(E) 反驳Herodotus不会接见任何人的说法
文中的42-46行中写的是在大多数情况下，我们只能猜测Herodotus采访叙述者的地点，跨文化交流的障碍等，所以这里说的是Herodotus采用的方式确实有很多不确定的因素。

例题2
2014年5月SAT真题阅读解析Section5 Questions
The movement of animals in the Arctic is especially
40 compelling because the events are compressed into but
a few short months. Migratory animals like the bowhead
whale and the snow goose often arrive on the Iasi breath
of winter. They feed and rest, bear their young, and prepare
for their southward journey in that window of light before
45 freeze-up and the first fall snowstorms. They come north in
staggering numbers, travel hundreds or even thousands of
miles to be here during those few weeks when life swirls in
the water and on the tundra and in the balmy air. Standing
there on the ground, one can feel the land filling up, feel
50 something physical rising in it under the influence of the
light, an embrace or exaltation. Watching the animals come
and go, and feeling the land swell up to meet them and then
feeling it grow still at their departure, I came to think of the
migrations as breath, as the land breathing. In spring a great
55 inhalation of light and animals. The long-bated breath of
summer. And an exhalation that propels them all south in
the fall.
15. The final paragraph of the passage serves primarily to
(A) summarize an account of a gradual change
(B) convey a personal reaction to an occurrence
(C) outline a bold new theory regarding an event
(D) provide an explanation for a seeming contradiction
(E) introduce an unusual example of an annual process
答案：B
考点：推断题
解析：文章的最后一段只要是为了?
(A) 总结动物逐渐迁徙的描述
(B) 对于一种现象的个人反应
(C) 对于一件事情提出大胆的理论
(D) 对于一种冲突的解释
(E) 介绍一种每年进程的反常例子
文章的第53-55行中提到“I came to think of the migrations as breath, as the land breathing. In spring a great inhalation of light and animals.” 从这一句话中可以看出这是作者对于动物迁徙这种现象的感想。
