精要的文字。
2．首先要结合主旨大意，选取与文本主旨密切相关的词语。它们通常是名词(短语)、 动词(短语)和形容词(短语)等实词。这些实词有可能以原词、代词、同义词、近义 词或反义词的形式重复出现，但提炼时不能重复关键词。
3．提取关键词时，必须注意句子间的关系。不要在表达相同或相近含义的句子里重 复提取关键词，如议论文的段落中常有主题句和结论句，结论句通常用不同的表 达方式重申主题句的含义，因此没必要在结论句中再次提取关键词。
微技能三 如何提炼关键词
60词左右的概要不允许照搬含有主题和支持性信息的原句。为了使独立表达成为 可能，你必须学会提炼关键词，提取关键词主要考查学生概括思想内容，提取关键信 息的能力。说到底就是要善于提取“核心信息”，善于提炼恰当的词语来表达内容。 关键词一般是名词、动词、形容词，不会是虚词。 1．“提炼”是一个弃．芜．存．精．的过程，因此要做到精炼，也就是说提炼的结果是获取最
lying will try to look at you in a strong way
词有“not look you in the eye”和“look
because they want to convince you they are
at you in a strong way”，因此它们可

【即时演练】 画出本文的主题句和关键词。
Human beings are smart.However, it seems that people are gradually losing their smartness as smartphones become more and more important assistants in their lives, reported news website Record Japan on Oct.22.As we rely too much on technology instead of our brains, many people have lost three basic abilities, said the website.
The first skill many people have lost is remembering phone numbers.Because phone numbers are stored in smartphone contacts, there is no need to dial a number or look at it again.And people may also have lost their sense of direction because navigation apps can guide people anywhere they want to go.These apps can even find shortest routes for you and avoid traffic jams.But the worst lost skills may be social ones，meaning that some people are becoming socially inept( 无 能 的 ) ． People often bury themselves in their smartphones.As we are too addicted to what’s happening in the virtual world，some of us have lost conversational skills and sometimes can’t even tell whether a person is happy or not.
4．就主从复合句而言，关键词通常在主句部分，而非从句部分，但含有宾语从句的 主从复合句例外，关键词应在宾语从句部分。
【典例示范】 1．画出该段的主题句。 2．根据主题句，画出关键词。
Sometimes you can tell if a person is lying
主题句的主旨大意是通过观察
by observing what they do with their body.
“what they do with their body”来判断
Sometimes a person who is lying will not look 一个人是否在撒谎。下面的支持性
you in the eye．Other times the person who is 信息里和该主旨大意密切相关的实
答案 主题句：However, it seems that people are gradually losing their smartness as smartphones become more and more important assistants in their lives. 关键词： lost three basic abilities，remembering phone numbers，have a chance to get these abilities back，device-free time.
Luckily, people still have a chance to get these abilities back.You should try to keep your parents’ number in mind for emergencies.You should also pay more attention to street signs and stores, which will help you to draw a mind map and prevent you from getting lost.And the easiest solution to social skill loss is to take a break from electronic devices because we are social creatures.We need device-free time.
