1. Their task list includes measuring the geography and terrain of the far side of the moon and detecting ____ underneath the lunar surface.2. To conduct the first exploration on the far side of the moon in history, Chang'e-4 and Yutu-2 received massive technological and on-board equipment ____.3. Thanks to this upgrade, the Yutu-2 rover can pass over rocks with a diameter of up to 20 cm. It is capable of bypassing and ____ obstacles and climbing up slopes.4. Since there is no ____ on the moon, the temperature there can fluctuate within a range from minus 183 degrees Celsius in the dark to 127 degrees Celsius in the light.

题目解答

答案

1. minerals 2. upgrades 3. overcoming 4. atmosphere

解析

本题考查根据上下文选择恰当词汇的能力，需要结合语境理解和学科知识。题目涉及月球探测任务的相关内容，需注意以下关键点：

  1. 学科常识：月球背面探测任务的目标（如地理测绘、矿物检测）、探测器的技术升级、月球环境特点（如无大气层导致温差大）。
  2. 词汇搭配：动词与名词的固定搭配（如“detecting minerals”）、动词形式的统一（如“bypassing and overcoming”）。

第1题

关键点：任务是“测量地理地形”和“检测月面下的物质”。

  • “detecting”后需接名词，表示“检测某种物质”。
  • 月球探测任务中，检测地下物质通常指矿物质（minerals），而非水或生物，因此选minerals。

第2题

关键点：探测器需要“技术与设备的改进”。

  • “equipment”前需接名词，表示“设备的改进”。
  • “received”表示“获得升级”，因此选upgrades（升级）。

第3题

关键点： rover的动作需与“避开障碍”和“爬坡”并列。

  • 动词需与“bypassing”形式一致，用动名词（-ing形式）。
  • 克服障碍的动作是overcoming（overcoming obstacles）。

第4题

关键点：月球温度波动大的原因。

  • 科学常识：月球没有大气层，无法调节温度，导致极端温差。
  • 因此选atmosphere（atmosphere）。
