关键词汇（CEFR C1）
spreadsheets
B2A sheet of paper, marked with a grid, in which financial data is recorded and totals calculated manually.
Example:
"Can you go to spreadsheets? Can you go to so much more? But again, that's the world we now inhabit."
calculation
B2The act or process of calculating.
Example:
"together, or perform some other arithmetic calculation on them? If we instead have a really big document, a contract of some sort."
spellchecked
B2To check that words in written text are properly spelled.
Example:
"And we want to make sure that it is properly spellchecked? Well, the input there isn't numbers, but is all of the words and letters in that document."
implicitly
B1In an implicit or implied manner.
Example:
"Well, that's because by way of these columns or places do we implicitly, in our own mind, quickly do a bit of arithmetic?"
mechanically
B2In a mechanical manner.
Example:
"But the key here is that we needed another digit. To put it more mechanically, we needed more hardware."
equivalent

Example:
"or equivalently can they count even higher? And so now, even though we began the discussion down here"
alphabetically
B2(manner) In an alphabetical manner.
Example:
"where you have contacts these days? Sort of a digital version of a phone book. And those contacts are typically sorted alphabetically."
ambiguous
B1Open to multiple interpretations.
Example:
"But as we saw before with the circle and the square and the triangle, just saying draw a cube is ambiguous. At what angle should it be oriented?"
cleverness
B2The property of being clever.
Example:
"What is that? Well in my cleverness to get to Mike's name twice as fast, what if I go ever so slightly too"
proverbial
B1Used to replace a word that might be considered unacceptable in a particular situation, when using a well-known phrase.
Example:
"So this is kind of like the proverbial fork in the road, if Smith is among the names, let's do this. What do we want to do?"
