三、小华向大家讲述了一个团队探索玛雅古城的故事，一起来了解一下吧！阅读下面短文，选出最佳选项。
In Mexico, Luke and a team of scientists discovered a lost Maya city. It was covered by thick forests for centuries. The Maya lived there over 1,000 years ago. They were good at farming, writing, maths and building amazing stone buildings like temples(寺庙） and palaces.
▲ The main reason was that most work had to be done by hand to make a discovery. Scientists had to cut down overgrown plants as they walked through the forest. It was hard and took lots of time.
Later, a technology, LiDAR, makes it possible for scientists to discover hidden ancient villages more easily. To use LiDAR, scientists fly a tiny flying machine over an area. The machine sends out thousands of laser beams(激光束). By recording how long it takes for the beams to return to the machine, scientists can make a 3D map of the ground below. This way, scientists can further study the remains long before they finally enter them.
However, Luke's team was not able to use LiDAR because it was too expensive. Luckily, Luke found a 2013 LiDAR map online made by other researchers. When Luke and his team studied the information, they were surprised to find thousands of Maya structures（建筑） which made a large city. The city even had a field for ancient Mayan ball games.
Luke believes that their discovery means there is a lot more to discover in that area. They plan to enter the newly discovered city to continue their research. “Maya cities are completely different from modern ones,” Luke said. “Studying them can give us ideas to make our cities better.”
()1. Which of the following can be put in the “▲” in Paragraph 2?
A. When did Luke make this important discovery?
B. Why did the city remain undiscovered for so long?
C. How long did it take for scientists to discover the city?

()2. What do the underlined words “the remains” in Paragraph 3 mean?
A. 3D maps. B. Thick forests. C. Ancient villages. D. Laser lights.
()3. How did Luke and his team discover the Maya city?
A. With the help of some photos.
B. By entering the forest in person.
C. With the help of a LiDAR map.
D. By making a 3D map with a machine.
()4. What does Luke talk about in the last paragraph?
A. The value of this discovery.
B. The abilities of his team.
C. The customs of ancient people.
D. The difficulties they faced.
()5. What is the best title for the passage?
A. More Technologies for Research
B. Hidden Maya City Found
C. Meet the Powerful Ancient Maya
D. New Technology Discovered

答案
1.B 2.C 3.C 4.A 5.B
解析
1. 第2段空格后句子以"The main reason was..."开头，是对原因的回应，结合后文内容解释了这座古城长久未被发现的原因是早期探索全靠人力、难度大耗时长，和B选项的问题语境完全匹配。A选项询问时间、C选项询问耗时、D选项询问过程中的困难，均无法和后文的"The main reason"形成对应逻辑。
2. 第3段前文提到LiDAR技术可以帮助科学家更容易发现隐藏的古村落，"the remains"指代前文提到的被隐藏的古村落这类古代遗迹，因此选C。
3. 根据第4段内容，Luke的团队负担不起自行使用LiDAR的成本，他们在网上找到了其他研究者制作的2013年LiDAR地图，通过研究该地图的信息发现了这座玛雅古城，对应C选项。
4. 最后一段Luke提到这次发现意味着该区域还有更多待探索的内容，研究玛雅古城可以为优化现代城市提供思路，这些内容都是在阐述本次发现的价值，对应A选项。
5. 全文围绕科学家团队发现隐藏的玛雅古城这一核心事件展开，介绍了古城的背景、早期探索的难点、用到的相关技术以及发现的意义，因此B选项作为标题最贴合全文主旨。
