高三英语复合句试题答案及解析
高三英语复合句试题答案及解析1. When travelling in America, we stayed in a quiet hotel, __________.A．next to it was a thick woodB．next to which was a thick wood.C．next to it there was a thick woodD．next to which a thick wood was【答案】B【解析】考查定语从句。
本题是非限制性定语从句，which就相当于前句中的the quite hotel ，所以was要在thick wood 前面。
句意：当在美国旅行的时候，我们呆在一个安静的旅馆，在旅馆隔壁是一片浓密的树林。
故B正确。
【考点】考查定语从句2. It was the middle of the night __ my father woke me up and told me to watch the football game.A．that B． as C． which D．when【答案】D【解析】由句子意思分析可知，my father woke me up and told me to watch the football game .作状语。
即my father woke me up and told me to watch the football game in the middle of the night是状语从句。
因此D选项正确。
如果在原题的短语the middle of the night前加个介词in 的话，那么就变成了强调句型（这样去掉it was...that ...三个词，句子意思完整，成分齐全。
所以此题选A选项是错误的。
句意为“ 午夜时分，我父亲叫醒我去看足球赛。
”。

分析句子，定语从句部分缺主语，引导词用关系代词且不可省略。
故可排除D项。

本题定语从句的先行词为复合不定代词everything故引导词只能为that不用which。

句意：这个塔楼，屋顶在这次可怕的暴风雨中被毁了，已经修复好了。
分析句子可知，______ was destroyed in the terrible storm是定语从句，故排除A、C项；定语从句修饰The tower，指物，引导非限性定语从句，用which，作of的宾语，相当于the roof of the house。
故选D。
