标题: SC求助！ can/could 如何区分？我跪倒
Foraging at all times of the day and night, but interspersing their feeding with periods of rest that last between one and eight hours, a sperm whale could eat so much as a ton of squid a day.

Abetween one and eight hours, a sperm whale could eat so
Bbetween one and eight hours, sperm whales can eat as
Cbetween one to eight hours, sperm whales could eat as
Dfrom one to eight hours, sperm whales could eat so
Efrom one to eight hours, a sperm whale can eat so
大家好呀~ 首先上正解 B
通过这道题，我想听一下大家关于 can/could wii/would 这类词的理解，我一直分不清，突然看到这个题，期待各位大侠的启发！
还有一个问题是 last 后面用的是 between and 不能用from to 吗？我觉得from to 也没毛病呀

小白发言
from to不是说要吃从一个小时到八个小时吗？而between and是说每次吃大约用一个小时到八个小时

but后面的从句有their 所以subject不能是a whale
其次应该是as adj as n 所以选B

至于could和can的区别...除了失态和态度，应该区别不大吧

（如有不对，请大神指点）

噢噢懂了，正解

但是之前我在OG上看到一道题目，好像就是用so as 表示比较的，难道我记错了？

总之很感谢！

之前在ron的视频中有看到过这个知识点。好像can和could不能随便，互用，要么在有明显过去时间点，作为can的过去式。要么用于虚拟语气。

在一个bolg看到了比较can和could用法的贴，这里贴一下could的用法：
*Use could (not can) to refer to conditional situations, in which something has to happen or be the case in order for someone to be able to do something or for something else to occur:
e.g. We could buy a new sofa if we stop eating takeaway meals every night.

*People often use could (never can) to talk about completely unrealistic situations, so as to deliberately exaggerate how they’re feeling at a particular time:
e.g.:
√ I’m so angry, I could murder her.
X I’m so angry, I can murder her.

To refer to a past unrealistic situation or strong inclination, use could have:
She was so thirsty, she could have drunk a gallon of water.
He irritated me so much that I could have screamed.

*Could have is also used (in a similar way to might) to show annoyance when you think someone should have done something, but they didn’t:
e.g.You could have told me that she wouldn’t be at work today!

感觉上这一题考点不在 CAN or COULD ，考点在主语的单复数，Between .. and ..
如果B 换成COULD ,一样OK
