Answer 3

One way to say this is with a construction for "must".

You basically say "Not doing so-and-so would be undesirable", though it translates as "must".

I can't really explain it sufficiently, so here's a link to a page that explains the construction in great detail:

http://www.guidetojapanese.org/haveto.ht...

Or you can just use the "want to" construction -- taking the stem of the verb and adding たい(tai)

For example:

To eat: 食べる (taberu)

The stem of "to eat": 食べ (tabe)

Want to eat: 食べたい (tabetai)

Or in the case of "I want (noun)", you should use the word 欲しい (hoshii).

For example:

"I want that car."

その車が欲しい（です）。

sono kuruma ga hoshii (desu).

欲しい is an i-adjective, so it can be conjugated like one:

"I do not want this hamburger"

このハンバーガーが欲しくない（です）。

kono hanbaagaa ga hoshitakunai (desu).

When a verb has "tai" on the end of it, it can be conjugated exactly like an i-adjective.

So for example, I don't want to eat is 食べたくない(tabetakunai)

Saying "I need to go shopping" using one of the "must" constructions:

買い物に行けなくてはだめ（です）。

kaimono ni ikenakute wa dame (desu).

Saying "I want to go shopping:

買い物に行きたい(です）。

Kaimono ni ikitai (desu).
