1. He's very nice but she has only known him three weeks.
- I think "..........for three weeks" is better, right? Only slightly. Both are fine.
2. Is "they're short of money" the same meaning as "they are broke"? They're very similar, but broke is worse.
3. Is "don't be afraid!" the same meaning as "don't panic!"? No,
but they are similar. You say the first if there is something
that might be frightening. You say the second if there is
something that might cause panic. Being afraid is often a
motionless phenomenon. Being in a panic is often characterized by
frenetic activity.
4. What is your favorite kind of music?
- Can I say "What is your favorite music?"? Yes, but "kind of music" is better.
