Many hotels use room keys that can automatically turn on an entry light and ___ the room's temperature controls, so guests never enter a dark room. (active)
题目解答
答案
根据题意,空白处需填入一个动词,与“turn on”并列。给定词根“active”可转化为“activate”,意为“激活”。完整句子为:
"Many hotels use room keys that can automatically turn on an entry light and activate the room's temperature controls, so guests never enter a dark room."
此处“activate”准确表达了“激活温度控制”的含义,符合句式与语义要求。
答案:activate
解析
本题考查词汇的词性转换。解题思路如下:
- 首先分析句子结构,“turn on an entry light”和空白处所在部分是并列结构,由“and”连接,所以空白处需要一个与“turn on”词性相同的动词。
- 题目中给出的是形容词“active”,我们需要将其转换为动词形式。“active”的动词形式是“activate”,意为“激活;使活动”。
- 把“activate”代入句子中,“activate the room's temperature controls”表示“激活房间的温度控制系统”,语义通顺,符合句子的逻辑和语境。
