It can use when you are talking about relationships between people and people. 〇かのじょと　わたしは　仲がいい。（She and I are really close.) 〇AさんとBさんは　仲がわるい。（A and B don't get along.)

Things that move on (walk) their own can say "います". ◯ともだちがそこにいます。（My friend is there.) ◯いぬがこうえんにいます。(A dog is in the park.) ◯むしが きに います。(There are insects in the trees.) あります ○ちょうちょの ひょうほんが テーブルのうえに あります。(A specimen of a butterfly is on the table.）←Because it doesn't move by itself.

Of course grammar is also important, but if only two months are available I think that you should learn a lot of vocabulary. And you should talk a lot with Japanese people.

Everyone is writing the correct answer, so I'd like to add a little to it. If there is this question in the Japanese test, the answer is not correct unless it is "ぜんぜん + negative form" lol

‎プレゼンテーションが(二回)あったり、試験が(一つ)があったり、テストがあったりします。 "～たり、～たります"といいます。(回数)はいわなくてもいいです。

うれしい" is an emotion that is happy momentarily. You can say it even when it is continuing to a certain extent. Example 〇プロポーズされてうれしい。 (I am happy to propose to him.) ○プレゼントをもらってうれしい。(I am happy to receive a present.) ○テストが100てんでうれしい。( I am happy to received a 100 on the test.) "しあわせ" is used when you are satisfied with the current state. Example ○けっこんせいかつは しあわせです。(His married life is happy.) ○すきなしごとができて しあわせです。(I am happy that I can do my favorite job.)

"た-fome with まま" and "ながら" can say Maintain "A" state and do "B". There is a moment verb in the verb, and "～まま" used for that verb. moment verb あけますOpen, たちますStand, すわりますSitting, つけますTurn on, etc 〇ドアをあけたまま でかけます。 〇テレビをつけたまま ねます。 〇たったまま ごはんをたべます。etc Another verbs can use with "ながら". Example かきますwrite、のみますdrink、たべますeat, erc 〇てがみをかきながら うたをうたいます。 〇コーヒーをのみながらケーキをたべます。

You can say when expressing objective properties, states and features. 〇わたしは 元気です。I am fine. 〇彼は元気です。 He is fine. But you can not say feelings and wants. "~みたい" is the same as "~ようだ". "～みたい" is colloquial than "～ようだ". There are several ways to use this word, but for your question can use it when you are guessing. Your example is correct. 〇彼女は食べたいみたいです。 〇彼女はアイスクリームが欲しいみたいです。 "たがる" can say other person emotions and demands. 〇わたしはかなしい。I'm Sad. ×かれはかなしい。 He is sad. But, if you use "たがる" you can say that. 〇かれは さみしがっています。 〇かれは本をほしがっています。 〇かれはレストランへいきたがっています。
