语义衔接是指通过上下文的语义来判断选项用词的，考查的方式主要有两种，一种是与词汇辨析等其他语法结合考查，需根据语义判断哪个词或短语合适，另一种则是根据上下文的原词复现进行考查，此时需选择原文词语。

【真题回放1】The study is a genome-wide analysis conducted on 1，932 unique subjects which_____pairs of unrelated friends and unrelated strangers.

[A]separated

[B]sought

[C]compared

[D]connected

解析　空格所在的句子为which引导的定语从句修饰study，空格应填入的动词为从句的谓语动词。因此补全定语从句为：the study……pairs of unrelated friends and unrelated strangers。根据文章的内容可判断，此处阐述的是实验的研究对象，只有[C]compared（比较）可以使句意符合逻辑和上下文语义，故为答案。[A]separated（分开），[B]sought（寻找）和[D]connected（连接）均不符合题意，且无法使从句合理。

【真题回放2】To assess the impact of music on surgical 4 , the researchers analyzed data from 47 studies, including 26 that looked at the effect of music before procedures，25 in the operating room, and 25 during recovery.

[A]research

[B]outcomes(www.daowen.com)

[C]results

[D]recoveries

The researchers had also hoped to examine the 18 of architecture, design and art on surgical outcomes but they didn’t find enough studies to assess this.

[A]impact

[B]effect

[C]influence

[D]affect

解析　这两项在文章中属于平行话题关系，第4题可根据第18题空格后的surgical outcomes（手术结果）得出[B]为答案，而第18题可以根据第4题空格之前的assess the impact（评估影响）得出[A]impact（影响）为答案。其中outcomes和impact都属于原词复现。
