这个今年的太阳好热。

this year=今年，跟today=今天一样

好像是似乎每年太阳更热都越来越热了。

The sun is so hot this year. It seems like the sun is getting hotter every year. Today, the sun was out at around 9am. This sun can burn people's skin. I don't like the hot sun because it makes me feel tired when I walk under it.
On Monday and Tuesday, the electricity company remembered us and gave us two days of electricity, which is rare. This is the first time I have seen this since I first lived here.

今天早上九点多太阳就已经出来了。

这个太阳可以晒伤人的皮肤。

我不喜欢很热的太阳，因为我走在太阳下的时候会让我觉得很累。

在这周一和周二，电力公司记得挂着我们，给了我们两天的电，这可是难得啊。

从我第一次住在这儿起，这是我第一次见过这件到这种事了。

这件事=this specific thing，这种事=this type of thing。联系上下文，这个句子用“这种事”比较好。
