第三部分 主旨类解题归纳总结
(一)经验总结: 1.把握逻辑结构，提高这方面的能力对于阅读议论文或说明文尤为重要，在此类文章中常用某个细节来引出题目从而进行议论，在议论的过程中可能会出现一些论据或细节描述，这部分常被设置为此类试题的干扰项。
2.找准主题句，主题句通常在文章句首，句中或句末，主题句表达中心思想，起主导作用，阅读时要对容易出现主题句的地方特别注意。 (二)主旨大意题的错误选项有一下特点： 1.以偏盖全。只是局部信息或者是一句没有展开论述的话。

2.过于笼统。即归纳的主题太宽泛，与细节脱节或者是没有对细节加以充分论述。 3. 把观点强加于作者。读者往往根据自己的常识对文章进行判断而忽视了作者的见解。 4.无关信息，即在文章中没有提到或者是找不到语言依据的信息。 当堂检测反馈：
主旨大意（查找、归纳法）解题经典应用 People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many
people multitask not out of a desire to increase productivity, but because they are easily distracted (分心) and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University
10
of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought
they
were
at
it,
and
how
sensation-seeking (寻求刺激) or imperative (冲动)they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple
mathematical
calculations
while
remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the
11
actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted. “People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things
that
are
not
as
important.”
Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused toward multitasking or whether people’s
recognizing
and
understanding
abilities change as a result of multitasking. The findings do suggest, however, why the sensation-seeker who multitask the most may
