In recent years, China has achieved remarkable advances in meteorological science, with the development of the “Haiyan” drone standing out as a major breakthrough. Created by the China Aviation Industry Group (AVIC), this unmanned aerial vehicle (UAV) has become an essential tool for improving the ___1___ (accurate) of typhoon forecasts.

The Haiyan series consists of two main types of drones ___2___ (tailor) for different observation tasks. The Haiyan I is built on the Wing Loong-10 platform, a jet-powered UAV capable of flying at high altitudes — up to 14 kilometers — at great speeds. In contrast, the Haiyan II uses the Wing Loong-2 airframe and is designed for ___3___ (endure). It can remain airborne for over ten hours, making it perfectly suited for long-term monitoring of large-scale weather phenomena.

The primary mission of the Haiyan drone is ___4___ (gather) atmospheric (大气的) data from remote or hazardous areas where human access is difficult. It is equipped with an advanced dropsonde (掷降探空仪) system: small sensor devices attached to parachutes are released from the drone during flight. As these dropsondes ___5___ (descend), they measure key variables such as temperature, air pressure, humidity, and wind speed. The collected data is transmitted in real time to the drone and then ___6___ (relay) to scientists on the ground. This process offers a detailed three-dimensional profile of the atmosphere within a weather system, greatly improving our understanding of storms like typhoons.

The Haiyan drone has already proven its ___7___ (practice) worth. In June 2025, for instance, the Haiyan I operated at an altitude of 11,000 meters to observe Typhoon “Butterfly”, setting a new record. ___8___ typhoons, the Haiyan II has also been deployed to study other complex weather patterns, such as the Northeast Cold Vortex, and to provide meteorological support for major events including the 2025 World Games.

Before the introduction of such drones, scientists relied mainly on satellites to monitor ocean-based typhoons. While satellites offer valuable large-scale views, they cannot capture ___9___ (detail) vertical measurements of the atmosphere. The Haiyan drone fills this gap — the high-resolution data it gathers is fed into advanced forecasting models at research centers, ___10___ (lead) to more accurate predictions of a typhoon’s path, intensity, and rainfall.

1.1.

A

B

C

D

解析：选accuracy。accuracy 考查名词。根据上下文可知，此处类比说明新技术提高科学研究精度，“the +名词”结构，所以用accurate的名词形式accuracy，表示“准确性”。故填accuracy。

2.2.

A

B

C

D

解析：选tailored。tailored 考查非谓语。分析句子机构可知，句子主干部分为：The Haiyan series consists of two main types of drones，句子成分和句意完整。因此题空处的动词tailor作非谓语；分析句意可知，此处表达这些机器人像“海燕”系列无人机一样“因特殊任务而被定制”，用过去分词表被动。故填tailored。​

3.3.

A

B

C

D

解析：选endurance。endurance 考查名词。根据“It can remain airborne for over ten hours”“海燕II”可以长飞行时间，由此可推知其耐久性，故用名词endurance。

4.4.

A

B

C

D

解析：选to gather。to gather 考查不定式。“be +动词不定式”结构表目的，这里研究团队的主要任务像“海燕”无人机一样是收集数据，所以用to gather。

5.5.

A

B

C

D

解析：选descend。descend 考查时态。根据原文描述客观事实可知，用一般现在时，主语dropsondes是复数，动词用原形descend，表示“下降”，这里将探空仪下降类比树叶飘落。故填descend。

6.6.

A

B

C

D

解析：选relayed。relayed 考查被动语态。分析句意“这些被收集起来的数据被实时传送到无人机，然后转发给地面的科学家们”，“The collected data ”和动词“relay” 存在被动关系，用被动语态。与前面的 transmitted并列。故填relayed。

7.7.

A

B

C

D

解析：选practical。practical 考查形容词。worth是名词，需要形容词修饰，所以用practice的形容词形式 practical，表示“实际的”。

8.8.

A

B

C

D

解析：选Beyond。Beyond 考查介词。根据后文“the Haiyan II has also been deployed to study other complex weather patterns”可知，除了当前提及事物之外还有其他，用介词beyond ，位于句首，首字母大写。故填Beyond。

9.9.

A

B

C

D

解析：选detailed。detailed 考查形容词。题空后的measurements是名词，要用形容词修饰，所以用detail的形容词形式detailed，表示“详细的”。

10.10.

A

B

C

D

解析：选leading。leading 考查非谓语。前文句子结构完整，再出现动词需要用非谓语结构，这里用现在分词leading作结果状语，表示自然而然的结果。故填leading。
