16.    Sometimes very odd things show up in ordinary places. In the 1800s,a strange sight began to be reported by farmers. Then in the 1970s, this strange event began to happen more and more often. People travelled for miles to stand in the fields and take photos of something they couldn't easily explain. What were they looking at? It was the crop circles—large and complex designs set into the middle of ordinary farm fields. No one could understand how these huge designs were made.

    Crop circles are found most often in fields of wheat, corn, or rice. They are usually created overnight, although some are reported to have appeared during the day. They have been seen in more than 70 different countries. Scientists have found that the plants inside a crop circle are drier than the ones outside it. The plant stems(茎) are bent but not broken in most crop circles, and sometimes the soil in the design has more iron than the soil outside of the design. Unfortunately, these facts alone do not help scientists answer their questions about crop circles. These facts only make them more mysterious.

    Some people believe crop circles are made by UFOs (Unidentified Flying Objects) landing in farm fields. Others think aliens are leaving us messages in the beautiful designs. Still others believe Earth energy under the ground makes plants bend over in designs. Some people say they actually made the crop circles with special equipment. Scientists have found some crop circles that are certainly made by people, but they are usually a little different from other crop circles. So who makes crop circles and why they make them can't be explained to this very day.

1. What does the underlined word "odd" in Paragraph 1 probably mean?
A. Big B. Bad. C. Unreal. D. Unusual.
2. It's generally thought that crop circles _____.
A. are made during the night
B. happen in the same places
C. are found in terrible places
D. have very frightening designs
3. Which of the following have the scientists proved?
A. Some crop circles are man-made.
B. UFOs help create some crop circles.
C. There actually are crop circles made by aliens.
D. Earth energy is one reason for crop circles' appearance.
4. What is the best title for the text?
A. The History of Crop Circles
B. Different Designs of Crop Circles
C. Crop Circles: The Unsolved Mystery
D. Crop Circles: The Great Influence on Farms

17.    While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be "taught" by a digital teacher, just like in the science fiction. Before you start imagining a human-like robot pacing around the classroom, Will is just an avatar(化身) that appears on the students' desktop, or the smartphone screen, when ordered to come.

    The autonomous animation platform has been modeled after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is assigned to teach Vector's "Be sustainable with energy"—a free program for Auckland's elementary schools.

    Just like the humans it replaces, Will is able to instantly react to the students' responses to the topic. Thanks to a webcam and a microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues randomly. For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps attract the students' attention, but also allows the program's developers to monitor their engagement, and make changes if needed.

    Nikhil Ravishankar believes that Will-like avatars could be a novel way to catch the attention of the next generation. He says, "I have a lot of hopes for this technology as a means to deliver cost-effective, rich and educational experience in the future."

    The program, in place since August 2018, has been a great success thus far. Ravishankar says, "What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention. However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon."

1. What was special for some elementary school students in Auckland?

A. A digital teacher taught them.

B. They first saw something digital.

C. This was the start of a new school year.

D. They could get close to the smartphone screen.

2. What is the benefit of this two-way interaction?

A. It can smile back.  B. It can use the microphone.

C. It can talk any topic for free. D. It can change if necessary.

3. What's Ravishankar's attitude to Will's replacing human educators soon?

A. Optimistic. B. Doubtful. C. Unclear. D. Disapproving.

4. What might be the best title for the passage?

A. New High Tech Contributes to Education

B. The World's First Digital Teacher Appears in the Classroom

C. The World's First Digital Teacher, a Help to Students

D. New Zealand Will Replace Teachers in Classrooms

答案以及解析

1.答案：gripped

2.答案：turn     out

3.答案：for

4.答案：sitting

5.答案：winding

6.答案：Taking

7.答案：(should) be prepared

8.答案：what

9.答案：at

10.答案：as

11.答案：burning

解析：考查非谓语动词。句意:当我瞥向窗外时,我突然看到远处的那座古老的塔楼正在燃烧。根据句意可知,此处表示"看到古老的塔楼正在燃烧",故用动词-ing形式作宾补。

12.答案：division

解析：考查名词。句意:很明显,这条河是这座城市新旧区域的分界线。根据the和句意可知此处用名词，division在句中表示"分界线"。

13.答案：Stunned

解析：考查非谓语动词。句意:许多人对选举结果感到震惊,怀疑这位候选人在选举过程中作弊了。分析句子结构可知,空处应填非谓语形式因stun 与主语 many people 之间是逻辑上的动宾关系,故填Stunned。

14.答案：to see

解析： 考查固定搭配。句意:离别了20多年后,他再也抑制不住去看望父母的冲动。the urge to do sth.意为"做某事的冲动",为固定搭配。

15.答案：explosion

解析：考查词形转换。句意:调查人员说可能是燃料爆炸导致了飞机失事。由空前的a可知,空处应填名词explosion。

16.答案：1-4 DAAC

解析：1.词义猜测题。根据第一段中的“...a strange sight…something they couldn't easily explain.”以及“No one could understand how...”可知，这些提示信息均是说一些人们无法理解的不寻常的事情。

2.细节理解题。根据第二段中的“They are usually created overnight...”可知，人们普遍认为麦田怪圈是一夜之间形成的。

3.细节理解题。根据最后一段中的“Scientists have found some crop circles that are certainly made by people…”可知，科学家已经证实有一些麦田怪圈是有人蓄意为之。

4.标题归纳题。文章第一段点出“No one could understand how these huge designs were made.”最后一段中的“…who makes crop circles and why they make them can't be explained to this very day.”再次点明文章的主题，即:麦田怪圈一直是个未解之谜。故C项作为标题概括了文章主旨。

17.答案：1-4 ADDB

解析：1.细节理解题。根据第一段中的They became the world's first kids to be "taught" by a digital teacher 可知，他们成为世界上第一批由数字化老师“教”的孩子。由此可知，特殊之处在于数字化老师教他们。故选A。

2.细节理解题。根据第三段中的This two-way interaction... changes if needed.可知，这种双向互动不仅有助于吸引学生的注意力，还允许程序的开发人员检查他们的参与度，并在需要时做出改变，由此可得出，其优势在于需要时可以做出改变。故选D。

3.推理判断题。根据最后一段中的However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon.可知，Ravishankar 认为它不会在短期内代替人类教育工作者。故选D。

4.主旨大意题。通读文章可知，从新学年开始，新西兰奥克兰的小学生将成为世界上第一批被数字化老师教的孩子。之后文章就此展开，由此可推断出The World's First Digital Teacher Appears in the Classroom最适合作本文的标题。故选B。
