考点18 说明文类七选五（解析版）
【命题解读】
实际上，“七选五”的题目选择不是个个都难，难就难在其中1～3道特别的题目上，这些题目或是因为蕴含的信息更为丰富，或是选项高度相似，或是逻辑关系相近，总让人感到很是纠结。那么，此时学生就要学会利用种种重复信息，达到抽丝剥茧的效果。
【解题技能训练思维导图】
原词重复信息
　　原词复现是指一个句子中的关键词(常为动词、名词、形容词)会反复出现在文中的其他句子中。这些词会以不同词类、词性、数、格、时态、语态等形式出现。如：“looks”与“looking”“looked”；“go”与“going”“went”等。根据语言****惯，第一句的宾语往往是第二句的主语，或者前后句有相同、重叠的词语。因此，要学会寻找空格前后句句中的相同关键词。
【例】　[2021·全国卷甲]Invite 5—10 people so you have a nice selection. 37.Less people than that, and there may not be enough things to choose from; more than that, and it becomes uncontrollable.
__38__.They should also prepare plenty of reusable bags to carry their “new” clothes home.
A．Less people than that
B．Hold a clothing swap
C．If two people are competing
D．Just keep music playing throughout
E．Donate whatever clothes are left over
F．Have everyone put their clothes in the right spots
G．Tell everyone to bring clean clothes in good condition
解析：本题考查原词复现。本段空白后“They should also prepare plenty of reusable bags to carry their ‘new’ clothes home.”讲他们还应准备大量的可回收的袋子，来把“新”衣服带回家。其中的“clothes”原词复现是解题提示，同时“new”表明衣服应该是好的，对应G选项中的“clean”“in good condition”。

代词重复信息
　　为了避免与上文提到的名词重复，用不同的代词指代上文提到的人、事物或事件。如：it指代单数名词、不可数名词、句子；they指代复数名词；ones泛指复数名词。还有反身代词、指示代词、关系代词等。
【例】　[2021·浙江卷1月]Researchers have a good way to deal with this problem. Make all customers stand in one long，snaking line—called a serpentine line—and serve each person at the front with the next available register. __34__ This is what they do at most banks and fast-food restaurants. With a serpentine line，a long delay at one register won't unfairly punish the people who lined up behind it. Instead，it will slow down everyone a little bit but speed up checkout overall.
A．Why does this always seem to happen to you?
B．So why don't most places encourage serpentine lines?
C．Some of them may have stood in a queue for almost an hour.
D．The chances of your line being the fastest are only one in three.
E．How high is the pro
