Why
🕵️interesting expression¶
Previewing the textbook, pp. 28–32. 为什么要用两个p?¶
The use of "pp." (plural) instead of just "p." (singular) is a convention in academic and bibliographic writing to indicate a range of pages. "p." stands for "page" and "pp." stands for "pages".
When you see "pp. 28–32," it signifies that the content or information spans from page 28 to page 32 inclusive. The use of the plural form helps to differentiate between a single page reference and a range of pages.
马丁·路德·金的名字为什么写成Martin Luther King, Jr.?¶
Info
We may get there someday as men of the caliber of Lincoln, Martin Luther King, Jr., and others build upon Washington's legacy.
"Junior"（缩写为"Jr."）是一个用于指代父子关系的称谓。当一个人的名字中包含"Junior"时，这意味着他是其父亲同名的儿子。通常，这种命名方式用来传达家族中两代人之间的直系父子关系。同理，"Sr." 是"Senior"的缩写，表示某人是家庭中的长辈或年长者。
例如，如果父亲的名字是John Smith，那么他的儿子可能被命名为John Smith Jr.，表示他是John Smith的儿子。因此父亲则被称为John Smith Sr.，表示他是家庭中的长辈。这种使用方式有助于清晰地区分家庭中不同代人的名字，并指示家庭成员之间的年龄或辈分关系。
句子中写成Martin Luther King, Jr.而不是Martin Luther King Jr.的原因是，在较正式或官方的场合，添加逗号以明确标示 "Jr." 是更为常见的做法，这种规范可能是出于清晰表达、避免歧义的目的。
使用i.e.表示：即，也就是。后面为什么加逗号？¶
Example
EV aggregator is a third party between energy supplier i.e., system operator and energy consumer i.e., EV user/owner.
在句子中使用 i.e.（即）时，逗号的作用是将解释或说明引入句子。逗号有助于突显解释性质的部分，使得读者更容易理解。在你提供的句子中，逗号用来引入解释性的部分，使得读者能够明确知道 "i.e." 后面的内容是对前面部分的解释，起到补充说明的作用。这样的使用方式有助于提高句子的清晰度和可读性。
最后括号内容表示额外说明¶
Info
“I would love to talk about happiness while making balloon animals at your granddaughter’s birthday party in Fairbanks!” Later, I may regret it. (No offense to your lovely granddaughter.)
只是举例说明要勇于说不，没有冒犯的含义。
语句中的括号内容（one hopes）表示什么意思？¶
Example
这句话中的“one hopes”是一种插入语，用来表示说话人的希望或期望。在这个上下文中，它表达的是说话人希望通过增加受教育的男性数量，这些男性将会（希望如此）变得不那么愤怒，这对于不得不与他们共享同一个世界的女性来说是件好事。
在这种用法中，“one”不指特定的人，而是用作不特定主语，相当于“人们希望”。“hopes”使用复数形式，并不是指多个希望，而是一种英语表达习惯，用来表达一种广泛或普遍的希望、期待或愿望,不是具体的、个别的愿望。

good luck on your quest! 怎么理解？¶
Example
在一个论坛的欢迎帖子里，有人回复到：welcome! good luck on your quest!
The phrase "Good luck on your quest!" is a common English expression used to encourage someone as they embark on a task, goal, or adventure. It essentially means wishing someone success in whatever they are about to undertake.
This phrase doesn't have a specific origin; it's widely used in literature, movies, games, and everyday language, especially in contexts involving a journey or mission. In fantasy novels, adventure films, or role-playing games (RPGs), characters often embark on quests, and this phrase is used to wish them well on their journey.
come in handy¶
Info
Don't throw that away—it might come in handy.
A few more traveler's checks may come in handy on the holiday.
In the phrase "come in handy," "come in" is an idiomatic expression meaning "to become" or "to prove to be." When we say something "might come in handy," it means that the item might become useful or prove to be helpful in the future.

时间UTC¶
实时查看时间：TIME.IS
UTC（Coordinated Universal Time，协调世界时）是全球时间标准，所有的时区时间都是基于它来定义的。UTC时间不受任何地区的地理或政治因素影响，是一种不随季节变化的时间标准。
UTC基于原子钟的精确计时，与地球的旋转时间（即世界时，UT）尽可能地保持一致。UTC是国际上通用的时间标准，常用于航空、航天、通信和网络同步等领域。
时区是基于UTC的，比如：
- 北京时间（China Standard Time, CST）是UTC+8，表示比UTC时间早8小时。
- 纽约的东部标准时间（Eastern Standard Time, EST）是UTC-5，表示比UTC时间晚5小时。
Abstract
北美东部时区的标准时间通常适用于秋冬季节。为更好地利用日照时间，春夏时节会采用夏令时（Daylight Saving Time，DST），时间会调早一小时，变为UTC-4。
