Are the following sentences acceptable?

(1) Jilly was glad to take the robot dog home as if she had got an invaluable treasure.

(2) After coming home, Jilly put it on the sofa and began to amuse herself by playing with the robot dog.

If #2 is a stand-alone sentence (with no prior context), it would be a good idea to swap "it" and "the robot dog."
If your idea is to have (2) follow (1) in a paragraph, than the "it" is okay; but I'd suggest changing "coming" to "arriving."

With #1, I'd say "as glad."
I'd use "acquired" instead of "got." Well, maybe that's a little too high-falootin' for the rest of the sentence. Maybe "received."

If you don't follow these, let me know. - A.

When I found out I had passed the exam, I was as happy as if I had just found out that I had won the Lotto.

The truth is, you didn't actually win the Lotto, and you know that.
The truth is, you didn't actually acquire an invaluable treasure, and you know that.

Hmmm. Wait a minute! You're right! I misinterpreted.
Perhaps a comma after "home" would help others not to make the same mistake.

I was very happy - as if I had just won a million dollars.
I was happy, as if I had won a million dollars.
I was as happy as if I had won a million dollars. (This is another way of expressing how happy you were.)

These are all fine. It was my error. I assumed you intended the double-"as" structure. Sorry. Emotion: embarrassed

By the way, now that you've combined the two sentences, it seems unnecessary to repeat "the robot dog."
It would perhaps be better to find another way to express it at the very end. Eg, "my mechanical pet," or something like that.

Best wishes, - A.

Hi,

My idea is to have (2) follow (1) in a paragraph. So, I revise the sentences as written. However, I am confused by what you suggest use "as glad" to replace "was glad."

Jilly was glad to take the robot dog home as if she had acquired an invaluale treasure. After arriving home, she put it on the sofa and began to amuse herself by playing with the robot dog.
