Making Comparisons.

In the Japanese language how do you make comparisons as in he/she looks like.... or smells like....

For example

She smells like flowers

He looks like a duck.

Yes I know they are weird sentences.

She smells like flowers.
- Kanojo wa hana no you na kaori ga suru.
kanojo wa = she (as the subject)
hana = flower(s)
hana no you na = like flowers
kaorii ga suru = has a scent..., smells

"... no you na" or "... no you ni" is "similar to/like (something)." But the sentence structures would differ depending on what you want to say.

He looks like a duck
...cannot really be translated in the same structure as above. Does he have a face like a duck? or does he move like a duck? :)
ahiru = duck
kare wa = he (subject)
- Kare wa ahiru mitai desu. (He is like a duck.) "... mitai desu" = resembles ...

If you want to talk about the specifics of where he is like a duck, then you can use the same structure:
- Kare wa ahiru no you na kao wo shite iru. (He has a face like a duck.) kao = face
- Kare wa ahiru no you ni arukimasu. (He walks like a duck.) arukimasu = to walk

Sorry I mixed the informal speech and the polite speech in the above post..

- Kare wa ahiru mitai desu. (He is like a duck.) "... mitai desu" = resembles ... POLITE SPEECH
- Kare wa ahiru mitai da. (He is like a duck.) "...mitai da" = resembles INFORMAL SPEECH

- Kare wa ahiru no you ni arukimasu. (He walks like a duck.) arukimasu = to walk POLITE SPEECH
- Kare wa ahiru no you ni aruku. (He walks like a duck.) aruku = to walk INFORMAL SPEECH
