题目解答
答案
A. plug
解析
本题考查词汇辨析,解题思路是理解句子的语境,明确需要一个能表达“将产品连接到电源板”意思的动词,然后分析各个选项的含义,选出符合语境的选项。
- 首先分析句子 “If you ____ all of your products into a power strip(电源板)and flip off the power strip when these items are not in use, they are truly off.” 的意思,其表达的是如果你把所有产品____到电源板上,并且在不使用这些物品时关掉电源板,它们就真正关闭了。
- 接着看选项:
- A选项 “plug”,“plug...into...” 是固定短语,意为“把……插入……”,“plug all of your products into a power strip” 即“把你所有的产品插入电源板”,符合句子语境。
- B选项 “prevail”,常见含义为“盛行;战胜;说服”,如 “The custom still prevails in the area.”(这种习俗在这个地区仍然盛行。),与“将产品连接到电源板”的意思不相关,所以该选项不符合。
- C选项 “preserve”,意为“保护;保存;保留”,例如 “We should preserve our cultural heritage.”(我们应该保护我们的文化遗产。),不能用于描述将产品连接到电源板的动作,因此该选项不正确。
- D选项 “pledge”,有“保证;发誓;抵押”等意思,比如 “He pledged to support the project.”(他保证支持这个项目。),与句子所需的“插入”含义不符,所以该选项也不合适。
