PAST MODALS - Would you please tell me whether the composition I've written below is correct and whether there are other possible options that I have missed?

"could"　→ does someone have the ability "would"　→ does someone have the availabilty

For each situation, write a sentence using past modals of speculation andwith the following phrases: For each situation, write a sentence using past modals of speculation with the following phrases:

He .may/might/couldmight have been up late................... He might have been up late...................

"may"　→ asks for permission "could"　→ does someone have the ability

He .may/might/could have been up late................... He .may/might/could have been up late...................

All three are OK.

2. You studied really hard for athe test, but you failed. 2. You studied really hard for the test, but you failed.

I .....can't/couldn't have studied hard enough. I couldn't have studied hard enough.

This is speculation so it's subjunctive case.

I .....can't/couldn't have studied hard enough. I .....can't have studied hard enough.

“Must not” sounds most natural to me, and “can’t” sounds less natural but still OK, but “couldn’t” doesn’t sound natural to me in this context.

(Is "I must not have studied hard enough " also possible? )............... (Is "I must not have studied hard enough" also possible? )...............

Yes, I think so but I think they want you to use some form of "could."

(Is I must not have studied hard enough also possible? )............... (Is I must not have studied hard enough also possible? )...............

Yes, it is good.

She ........must have fallen asleep (Is it also possible to use may, might, could have fallen asleep? )............. She must have fallen asleep (Is it also possible to use may, might, could have fallen asleep? ).............

Yes, as in, "She might have fallen asleep." I think this is how you're supposed to answer. Remember: "may"　→ asks for permission "could"　→ does someone have the ability

She ........must have fallen asleep (Is it also possible to use may, might, could have fallen asleep? )............. She ........must have fallen asleep (Is it also possible to use may, might, could have fallen asleep? ).............

Yes, must, may, might & could are all possible here.

We ......may/might/ couldmight not have brought enough food.............. We might not have brought enough food..............

"might" → possibility

We ......may/might/ could not have brought enough food.............. We ......may/might/ could not have brought enough food..............

All three are possible. “May” & “might” would both mean “it’s possible that we didn’t bring enough food.” “Could” would mean “there was no possible way that the amount of food we brought would have been sufficient” (because we’re both gluttons, for example).

You think he might be at his hotel by now. You think he might be at his hotel by now.

now.

He .......will /may/ might /couldmight have checked into the hotel by now............. He might have checked into the hotel by now.............

They give the answer, "might," in the prompt, too.

He .......will /may/ might /could have checked into the hotel by now............. He .......will /may/ might /could have checked into the hotel by now.............

All four are possible, although I don’t think “will” is a modal.

■ CWould you please tell me the difference between crash, nosedive, plunge, and tumble? ■ Would you please tell me the difference between crash, nosedive, plunge, and tumble?

These all connote a decrease. In increasing order of magnitude, it's the following: - tumble (small decrease) - plunge - nosedive - crash (very large decrease)

For crash, I think the fall is the most dramatic when compariamong all these options. For crash, I think the fall is the most dramatic among all these options.

I agree.

Nosedive must be sudden, really fast and straight. Nosedive must be sudden, really fast and straight.

Yes, I agree but it doesn't hit bottom like crash.

Plunge is straight and rapid, and tumble is impressive but it should be at an angle , so not as fast as in the case of the other options (t. This fall resrembles a rock falling down a mountain and msking a rotating movement)rotating as it goes. Plunge is straight and rapid, and tumble is impressive but it should be at an angle, so not as fast as in the case of the other options. This fall resembles a rock falling down a mountain rotating as it goes.

Yes, the visual is correct.
