Pros and cons of the summer
There are two sides of each coin, including the attributes of summer.
I enjoy summer weather and the (1) sun, but I need to be careful to prevent me and my family from <s style="color: rgb(230, 0, 0);">the</s> sunstroke and <s style="color: rgb(230, 0, 0);">the</s> sunburn<s style="color: rgb(230, 0, 0);">s </s>(2). Moreover, recently I've found out that the pincers (3) like warm weather as much as I do. To be honest, I'm afraid of these insects.
Flowers are blooming, and that's amazing, but after the move I started suffering from <s style="color: rgb(230, 0, 0);">the allergy </s><s style="color: rgb(0, 138, 0);">a</s>llergies, and it's unbearable. I've never had such <s style="color: rgb(230, 0, 0);">itching</s> itchy eyes and a stuffy nose as I have now for almost two months.
Summer fruits and berries are sweet and they give us necessary vitamins and fiber, (6) but they are rather expensive.
Only swimming doesn't cause any problems for me. However, (5) It's just too hard to organize as getting to a nearest lake takes us more than 40 minutes by two different buses. It's not a pleasure to go there with kids. Taking into account that we can't spend too much time at the beach, it becomes an exhausting activity.
Nice, I enjoyed the contrast and how you described the good and bad of different things. I understood everything and you only made a few small mistakes. the main mistake was when to use a definite article which I've heard is a difficult thing for Russian speakers and either way the rules are kinda weird and complicated. Good work.
(1) definite article; is ok but sounds slightly weird to me.
(2) sunburn and sunstroke don't need a definite article ("the"); they are both also always singular.
(3) I don't know what pincers are but it might not be wrong. You mean like an "earwig"?
(4) should use the plural and don't need definite article because it is a non-specific thing. You could alternatively say <em style="color: rgb(0, 102, 204);">a pollen allergy.</em>
(5) not wrong but maybe adding these words makes it flow better.
(6) Again not wrong but you don't need to use a comma before "and" and "but". You can but its controversial, <a href="https://en.wikipedia.org/wiki/Serial_comma" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 102, 204);">https://en.wikipedia.org/wiki/Serial_comma</a>.
