高考英语连词知识点经典测试题附答案
高考英语连词经典习题(含答案)
A．that B．when C．which D．what
A．before B．where C．until D．when
【答案】A
【解析】
【详解】
考查从属连词辨析。句意：据一些目击者称，一名拾荒老人还没来得及救助那个女孩，女孩就随后再一次被货车撞倒。A. before在...之前；B. where在哪里；C. until知道；D. when当...时候。分析句子可知，本句缺少从属连词，根据句意，before符合句意。故A选项正确。
A．that B．which C．for which D．to which
【答案】C
【解析】
C考查非限制性定语从句。However为插入语，先行词为The position，定语从句中的短语apply for意为申请，所以应填for whiCh，此时whiCh做apply for的宾语。故选C。
8．I usually sleep with the window open ________ it is really cold.
3．I’m sorry I got caught in the traffic；_________, I could have been here sooner．
A．besidesB．although
C．anywayD．otherwise
【答案】D
【解析】考查含蓄虚拟条件句。I could have been here sooner是和过去事实相反的虚拟语气，四个选项中只有otherwise可以充当含蓄虚拟条件，相当于if I had not got caught in the traffic.所以选D。
