А пойдёмте-ка* в парк!

Привет! Мне кажется, что (2)сейчас самое время отложить все учебные\рабочие дела, чтобы пройтись (3)на свежем воздухе.

Grammar issue

• * When you want to soften the imperative form, you shall add “-ка” as the ending.

• (2) Literally, it means “now is the time”, “now would be the time” and after the infinitive follows.

• (3) Usually, when we use the preposition “на“, we mean something is on the surface. However, we have a good deal of set expressions and this is not an exception. This one means “in the fresh air”, “outdoors”.

• (4) Let’s desipher the verb понаблюдать
  по+наблюд+ать
  The verb of the first conjugation because it has the ending -ать.
  Наблюдать means “watch for someone/something for” a long period of time. For example: "я за тобой наблюдаю", "мне нужно за тобой наблюдать" or “я наблюдаю за тобой”, “мне нужно наблюдать за тобой”. You can ask, what’s the difference? And I’ll answer — you want to emphasize on something? Change the order. Anyway, the endings are the same, everything is preserved, so meaning won’t be changed except the tone. Whether I do it because of YOU or I do IT because I want to do IT.
  Why the prefix was added? Well, here it means to highlight the time of the process won’t take long.
  Try to conjugate the verb наблюдать in past and future tenses, in plural and single forms and let me know your results.
