I think you have to write sentences for each of the idioms.
Example:

When I had the flu, I was sick as a dog.
For example, Mars and Earth is a small and big planets that's why they are like the best of both worlds.
ok thank you so much for you help i real appreciate it
Your welcome
Kalie, please post correct sentences ... or don't post at all.
Another example:

When I can work from home, I have the best of both worlds because I can be a stay-at-home mom and also do the work that I love.
I just made up the sentence, but I used the idiom.
