A
Since May 8, Boston Dynamics’ dog-like robot,Spot, has been in use at Bishan-Ang Mo Kio Park in Singapore to help encourage social distancing during the COVID-19 pandemic (新冠肺炎疫情) according to a report in the South China Morning Post.
Singapore’s government is funding the experiment of the robotic dog, which will last for two weeks at the park during off-peak (非高峰的) hours.
“The robot isn’t enforcing (强制).It’s just giving people information and encouraging them,” Boston Dynamics founder Marc Raibert told CNBC.“When Spot is patrolling (巡逻) the area, there’s a parks officer nearby who can do whatever enforcement he decides is suitable.”
Cameras fixed on Spot will scan the surroundings and help officers work out the number of visitors in the park, but they cannot read faces and won’t collect any personal information.It also carries a loudspeaker to broadcast a pre-recorded message to remind visitors of the importance of social distancing.
Without enough manpower, Singapore is turning to robotics to reduce the manpower required for park patrols and remind people about the risks they may be putting themselves and others in.
The question, however, is whether their use of Spot will be a good tool or will only attract more people to it instead.
If the two-week experiment proves successful, the government will consider using Spot at the park during peak hours.Singapore will also do studies to see if it’s worth using other Spots in other parks.Already, Singapore engineers are trying to improve Spot, making it tell if people are together in a group or strangers passing on the grass.
No one knows if Spot will stay after the pandemic is gone, but one thing is for sure: the robot is the hardest working dog in the world.
(  )41.Why is Spot used at Bishan-Ang Mo Kio Park
A.To draw visitors’ attention to it. 
B.To help encourage social distancing.
C.To read and record visitors’ faces.
D.To help collect private information.
(  )42.How long will the experiment of the robotic dog last
A.Two weeks during off-peak hours. B.Two weeks during peak hours.
C.15 days. D.three weeks.
(  )43.The underlined word “they” in Paragraph 4 refers to (指的是)   .
A.visitors      B.strangers 
C.cameras D.officers
(  )44.What can we learn from the last 3 paragraphs
A.The experiment is still in progress. 
B.The use of Spot proves to be a good tool.
C.Spot will stay after the pandemic is over.
D.Singapore will no longer need other Spot robots.
(  )45.According to the passage, which of the following is TRUE
A.Spot scares people into keeping a distance in public.
B.Spot patrols the park for two weeks during peak hours.
C.Spot can tell people together in a group from strangers passing by.
D.The parks officer nearby decides on the enforcement instead of Spot.
B
Why are dogs our best friends Maybe because they can understand our words much better than we thought, according to a study in Hungary.It found that dogs understand not only what we say, but also how we say it.
  “The results were very exciting and very surprising,” said researcher Attila Andies, from Eotvos Lorand University in Budapest.
  For the study, the researchers first trained 13 dogs for months.The dogs had to sit quietly inside machines, so that the researchers could check their brain activity.Then the researchers put headphones on dogs and played people’s voices to them.There were four different voices.Some were positive words, such as “well done”, or neutral(不带感彩的) words like “however”.The words were also in different tones(音调).Some were positive and some were neutral.
  Brain scans(扫描)showed that the dogs could recognize(辨认)words, as well as the tone of words, much like people do.The positive words with a positive tone brought the stronger activity in their brain’s reward centers(奖励中枢).
  “It shows that for dogs, a nice phrase can work very well as a prize,but it works best if both words and tones match,” said Andies.
  They also found that dogs deal with meaningful words with the left side of the brain and tones with the right.Human brains work in the same way.
  It gave us a new understanding of language, said Andies.That is, not only do humans understand the meaning in words, other species(物种)do too.
(  )46.What was found according to the study in Hungary
A.Dogs can’t understand people’s words.
B.Dogs can only understand what we say.
C.Dogs can understand what we thought better than our words.
D.Dogs understand not only what we say, but also how we say it.
(  )47.Which of the following is NOT mentioned in the study
A.Researchers played with the dogs.
B.Researchers made dogs sit inside machines.
C.Researchers scanned the dogs’ brains.
D.Researchers played people’s voices to the dogs.
(  )48.Dogs think     as a best prize.
A.neutral words with a neutral tone
B.neutral words with a positive tone
C.positive words with a neutral tone
D.positive words with a positive tone
(  )49.According to the passage, which of the following is TRUE
A.Human brains don’t work in the same way as dogs do.
B.Dogs deal with meaningful words with the left side of the brain.
C.The researchers trained the dogs for years to check their brain activity.
D.Researcher Attila Andies was disappointed at the results of the study.
(  )50.What is the main idea of the passage
A.Dogs are as clever as humans.
B.Dogs are good at learning humans’ language.
C.Dogs can understand the meaning in words.
D.Dogs can do what humans do.

  Edison often said, “I will discover what the world needs, then I will try to invent it.”It is true that he spent more than any other man of his time in inventing things.He made more than one thousand inventions in his life and all these have changed our way of living.Edison was one of the greatest inventors in the world.
When Edison died in 1931, someone said people should turn off all the lights in their homes, streets and factories for several minutes in honour of this great man.Of course it was impossible to do so.But this shows what Edison’s inventions mean to people’s lives.

21.C 考查分数表达法。句意:我班上大约三分之一的学生不喜欢在网上学习,因为他们不能和同学们讨论。分数用“基数词+序数词”来表示,分子是基数词,分母为序数词,当分子为one时,分母用单数。
22.B 考查动词短语辨析。句意:我认为年轻的低头族应该减少花在智能手机上的时间。cut off 意为“切断”;cut up 意为“切碎”;cut in 意为“插入”;cut down意为“削减”, spend...on sth.在某事上花费……。
23.C 考查介词辨析。下文for引导的原因状语从句说明王先生没有回家,用介词except表示“除……之外”,表达的是一种排除关系。
24.A 考查动词短语辨析。句意:——泰德,什么东西这么难闻 ——对不起,我要脱下袜子,把它们放进洗衣机。根据后面说把它们放进洗衣机里可知此处表示脱下来,其他三项意思:B分发、公布;C举起、提高;D不接近、防范、远离。
25.A 考查连词短语辨析。句意:——玛丽,昨晚谁参加了毕业聚会 ——几乎每个人都去了。不仅有很多学生,而且王老师也出现在了聚会上。not only...but also...不但……而且……;neither...nor...既不……也不……,两者都不;either...or...或者……或者……,不是……就是……。
26.B 考查名词辨析。下文“在使用之前”,instruction意为“说明;说明书”,句意:但在使用之前请仔细阅读说明书。
27.B 考查连词辨析。句意:北京的餐馆必须停止提供免费塑料袋,除非顾客要求。since既然,由于;unless除非;because因为。
28.C 考查名词辨析。suggestion和advice都表示“建议”但suggestion是可数名词,而advice是不可数名词,不与不定冠词连用,没有复数形式。
29.C 考查关系代词辨析。句意:杜甫是一位伟大的中国诗人,他受到世界人民的欢迎。先行词poet指人,定语从句中缺少主语,因此关系代词应该用who。
30.A 考查动词辨析。suggest 意为“建议”,后跟宾语从句,应用陈述语序,排除B项。根据句意:我们都建议你不要在夜市吃东西。排除C、D两项。
31.B 考查动词。根据上句“deliver mails(递送邮件)”可知,飞行的机器人能把邮件运送到各家各户。
32.A 考查名词。由于这是一个飞行的机器人,因此其运送邮件时可以在天上飞而避免遭遇繁重的交通。
33.A 考查名词。根据上句“But they will spend too much time in returning.”可知,飞行机器人递送邮件虽然方便,但当其返回时却需要花费很多时间。由此推知,研究者试图通过信鸽的帮助来改进这个飞行机器人。
34.C 考查副词。本句解释了什么是信鸽。信鸽就是经过特殊训练从别的地方飞回家的鸽子。
35.D 考查动词。研究者经过研究“发现”了信鸽的作用。
36.B 考查副词。从上下文“通过信鸽引导飞行机器人回家”的描述可知,研究者发现,信鸽比飞行机器人更高效。
37.A 考查名词短语。由于信鸽比机器人更高效,因此研究者考虑把飞行机器人与信鸽放在一起去递送邮件。
38.C 考查动词。由于飞行机器人与信鸽一起去进行递送任务,因此在飞行机器人把邮件递送结束后,就会跟随信鸽飞回家。
39.D 考查动词。这个经过特殊训练的信鸽肯定需要花费大价钱饲养。
40.D 考查动词。尽管饲养信鸽花费不菲,但研究中心说,这能节省时间。节省的时间能弥补开销。
41.B 细节理解题。根据文章第一段中to help encourage social distancing during the COVID-19 pandemic.可知,机器狗放在公园里是为了让人们保持社交距离。
42.A 细节理解题。由第二段which will last for two weeks at the park during off-peak hours.可知,在公园里为期两周的非高峰时间实验。
43.C 词义猜测题。根据第四段第一句话可知they指代前句中的主语cameras。
44.A 主旨大意题。综合最后三段的陈述,可知机器狗的实验仍在进行中,应有前景和一些负面影响仍需时间来证明。
45.D 细节理解题。根据文中第三段最后一句可知附近的公园的管理人员替机器狗决定强制措施。
46.D 细节理解题。根据第一段尾句 “It found that dogs understand not only what we say, but also how we say it.”可知,研究发现,狗不但理解我们所说的话,还能理解我们说话的方式。
47.A 细节理解题。根据第三段“The dogs had to sit quietly inside machines”可知,这些狗被安放在一种仪器里面,故排除B项;根据第四段第一句“Brain scans showed that the dogs could recognize words, as well as the tone of words, much like people do.”可知,人们扫描狗听到声音时的脑部反应,故C项排除;根据第三段第三句“Then the researchers put headphones on dogs and played people’s voices to them.”可知,研究人员向这些狗播放人的声音,故D项排除。只有A项没有提及。
48.D 细节理解题。根据第五段“It shows that for dogs, a nice phrase can work very well as a prize”可知,美好的语句和语调对于狗来说就如同奖赏。
49.B 细节理解题。根据第六段第一句“They also found that dogs deal with meaningful words with the left side of the brain and tones with the right.”可知,狗用左脑处理有意义的语言,用右脑处理语调。
50.C 主旨大意题。通读全文可知,本文主要介绍了一项研究发现:狗不但理解我们所说的话,还能理解我们说话的方式;和人类一样,它们用右半脑处理语调,用左半脑处理语言。
