关联词及行文逻辑

考点1　关联词使用不当

[典例1] After looking at the toy for some time，he turned around and found where his parents were missing.(2015·全国Ⅱ)

分析　句意为：他转过身发现父母不见了。由句意可知宾语从句句意完整，不缺少成分，所以应该用that引导从句或省略。故去掉where或将where改为that。

[典例2] There the air is clean or the mountains are green.(2015·全国Ⅰ)

分析　两个简单句之间为并列关系而非选择关系，所以将or改为and。

考点2　多余或缺少连词

[典例1] Although we allow tomato plants to grow in the same place year after year，but we have never had any disease or insect attack problems.(2014·新课标全国Ⅰ)

分析　在让步状语从句中，although不可以与but连用，因为although位于句首，故只能去掉but或将but改为yet。

[典例2] He had a deep voice，which set him apart from others in our small town，he was strong and powerful.(2013·新课标全国Ⅰ)

分析　句中which引导的是定语从句，修饰主句He had a deep voice，而主句与从句后的分句he was strong and powerful之间缺少连词，根据他们的并列关系，确定he前加and。

考点3　介词与连词混用

[典例] In fact，he even scared my classmates away during they came over to play or do homework with me.(2013·新课标全国Ⅰ)

分析　句中during为介词，不可以连接两个独立谓语的句子，根据逻辑关系，后一个分句应为when引导的时间状语从句。故during应改为when。
