How to simply say "and" in Japanese, to coordinate two actions?

Question

How to simply say "and" in Japanese, to coordinate two actions?

My question is divided into two sub-questions: coordination inside one sentence, and coordination between two sentences.

• Coordination inside one sentence

For instance :

(1) I like to cook and to swim.

(2) Today, I went to the park and I studied in the library.

For (1), machine translation systems systematically give a sentence with the nominalization of the action words, linked by と.

For (2), these same MT systems systematically use the "て" form of one of the action verbs.

But I would like to make a sentence like : Pronoun + する + conjunction + する

Is there such a conjunction, and such a sentence pattern in Japanese?

• Coordination between two sentences

What would be the grammatical word to coordinate two sentences such as:

I went to the park. Additionally, I studied in the library.

N.b.: Of course, the machine translation output are simply given as illustrations. Indeed, I did not encounter such kind of conjunction and sentence pattern in my (beginner/intermediate) practice of Japanese.

Answer 1

Question 1: ("I like to X and Y", in one sentence)

私は料理することと泳ぐことが好きだ。
私は料理と水泳が好きだ。

You might not want nominalization, but I don't think you can get around it in this case. If you want to make it shorter, you can use nouns instead of nominalized verbs. 私は料理して泳ぐことが好きだ would not be what you want to say - it sounds more like you like to cook while swimming.

Question 2: ("I did X and Y", in two sentences)

私は今朝公園に行った。図書館にも行った。
私は今朝公園に行った。そして図書館に行った。
私は今朝公園に行った。それから図書館に行った。

The first option seems closest to "additionally", although the word you need to use doesn't come at the beginning of the second sentence. The last two options imply chronological order.
