2022年四川统招专升本《大学英语》模拟试题及答案（十二）

46. This is the best novel that I ________ in this field.

A. have read      B. has read      C. read      D. reads

【答案】A.

【解析】动词时态。根据句意可知，that引导的从句应用现在完成时，表示动作从过去某一时间开始一直延续到现在，并有可能延续下去。故选A。

47. It troubled him a lot ________ she refused to answer his call.

A. while      B. that      C. if      D. for

【答案】B.

【解析】主语从句。分析句子结构可知，It在句中作形式主语，真正的主语是空处引导的从句，所以应用在从句中不作句子成分，只起连接作用的that。故选B。

48. The fact has worried many scientists ________ the earth is becoming warmer and warmer these years.

A. what      B. which      C. that      D. though

【答案】C.

【解析】同位语从句。分析句子结构可知，空处引导的是同位语从句，先行词是fact，所以应用在从句中不担当语法成分的that来引导，that引导的从句是对fact(事实，真相)具体内容的解释说明。故选C。

49. A low-carbon (低碳) lifestyle has an effect ________ our daily life. People are paying more and more attention to ________ energies these days.

A. in; save      B. in; saving      C. on; save      D. on; saving

【答案】D.

【解析】固定用法和非谓语动词。have an effect on为固定搭配，意为“对……有影响”;pay attention to意为“注意，重视，留心……”，其中to为介词，其后的动词应用动名词形式。故选D。

50. The secretary worked late into night, ________ a speech for the president.

A. preparing      B. to prepare      C. prepared      D. was preparing

【答案】A.

【解析】非谓语动词。分析句子结构可知，空处应用非谓语动词，作伴随状语。又因work和prepare这两个动作同时发生，且prepare和其逻辑主语The secretary之间为主动关系，所以应用现在分词作伴随状语。故选A。
