1选择题
The 3D printing technology ______ by scientists in the 1980s is now widely used in engineering.
- A. invented
- B. is invented
- C. was invented
- D. inventing
答案:A
解析:本题考查非谓语动词作定语。句意为“在20世纪80年代由科学家发明的3D打印技术现在在工程中被广泛使用。”空格处需要一个非谓语动词作后置定语修饰technology。invent与technology之间是被动关系,且动作发生在过去,因此用过去分词invented。B和C是谓语动词形式,不能作后置定语;D是现在分词,表主动,不符合逻辑。易错点是误选C,以为需要谓语动词被动语态,但此处是短语作定语,非谓语动词。故选A。
2选择题
Could you tell me ______ the new AI robot will be put into service in our city?
- A. that
- B. when
- C. whether
- D. how
答案:B
解析:本题考查宾语从句的连接词。句意为“你能告诉我这个新的AI机器人将在什么时候在我们城市投入使用吗?”根据句意,询问的是时间,所以用when引导宾语从句。A. that引导陈述意义的宾语从句,此处是疑问句;C. whether表示“是否”,与语境不符;D. how表示方式,不匹配。易错点是忽略疑问词在宾语从句中充当的成分,误选C。故选B。
3选择题
— Do you know if he ______ to the technology exhibition tomorrow?
— I think he will go if he ______ free.
- A. will go; is
- B. will go; will be
- C. goes; is
- D. goes; will be
答案:A
解析:本题考查时态与条件状语从句。第一空是if引导的宾语从句,根据时间状语tomorrow,用一般将来时will go;第二空是if引导的条件状语从句,遵循“主将从现”原则,用一般现在时is。B项第二空错误;C项第一空错误;D项两项均错误。易错点是混淆宾语从句和条件状语从句中if的用法和时态规则。故选A。
4选择题
Great changes ______ in our city since the high-speed railway ______ into operation.
- A. have taken place; came
- B. have been taken place; came
- C. took place; has come
- D. were taken place; has come
答案:A
解析:本题考查时态和语态。第一空,since引导的时间状语从句用一般过去时,主句用现在完成时;take place“发生”,是不及物动词短语,没有被动语态,所以用have taken place。第二空since从句用一般过去时came。B项被动语态错误;C项时态错误;D项时态和语态均错误。易错点是误认为take place有被动语态,或混淆since主从句时态。故选A。
5填空题
The project ______ (complete) by the engineering team next month will improve the city's water system.
答案:to be completed
解析:本题考查非谓语动词作定语。句意为“下个月将由工程团队完成的项目将改善城市的供水系统。”project与complete之间是被动关系,且动作发生在将来(next month),因此用不定式的被动形式to be completed作后置定语。易错点是填入completed(过去分词,表被动但已发生)或completing(现在分词,表主动)。
6填空题
I wonder ______ (是否) the new energy car can travel 500 kilometers on a single charge.
答案:if/whether
解析:本题考查宾语从句的连接词。句意为“我想知道这辆新能源汽车一次充电能否行驶500公里。”表示“是否”,用if或whether引导宾语从句。易错点是写成that,或拼写错误。
7解答题
根据中文意思完成句子,每空一词。
到他们到达工厂时,那批新设备已经被安装好了。
答案:By the time they got to the factory, the new equipment had already been set up.
解析:本题考查过去完成时的被动语态。关键结构“By the time + 过去时”,主句用过去完成时(had done),且equipment与set up是被动关系,所以用had been set up。易错点是忽略被动语态,或用错时态(如用一般过去时)。
8解答题
请用定语从句将下列两个句子合并为一个句子。
The engineer is designing a smart robot. The robot can help with housework.
答案:The engineer is designing a smart robot that/which can help with housework.
解析:本题考查定语从句。先行词是robot,指物,在从句中作主语,所以用关系代词that或which引导。易错点是误用关系副词where或who,或在从句中重复使用代词it。
