Grammatically “that” is used to single something out from a group so it sounds natural in defining relative clauses. It sounds less natural in non- defining relative clauses when non-essential information is introduced, however I would imagine there are a huge amount of native English speakers who get this wrong in everyday speech. My advice is not to worry too much about formality or “why” and focus on learning a trick/ rule you can always remember. For example: use “that” for essential information and “which” for extra information.

In my opinion it’s more natural to say “I need to get my sh*t together”. It’s a common way of speaking but only in a very informal setting as “sh*t” is a swear word.

In my opinion，gas-powered cars are the main reason that greenhouse gases are increasing. As more and more carbon dioxide is released into the air, the earth will quickly become an actual greenhouse. The hot weather around the world have made some people realize that we must find some solutions to solve this problem. However, most people still think that this is not a big deal. They still enjoy their life while doing things which increase air pollution, including drving their cars around. I am really thankful for my country where the government makes a lot of effort to lead people to buy electric cars instead of gas-powered cars. I dont think that it's effective to reduce air pollution by encouraging people not to drive cars for only one day. We have been told to prevent our world from being destoryed by greenhouse gases for many years, but how many countries or people actually did something about it? Some people still enjoy the sound waves from the engines, then go into a house with air conditioning

This is a really good question! “I wouldn’t believe it” indicates that this is something you believe in the present. “if I hadn’t seen it with my own eyes” indicates that that you saw something in the past. “I wouldn’t believe it if I hadn’t seen it with my own eyes” indicates that you saw something in the past which has affected what you believe in the present. In this example the past thing you saw is relevant to the present moment. “I wouldn’t have believed it if I hadn’t seen it with my own eyes” is talking firmly about a past event, the emphasis is on what you saw and believed in the past with less relevance to the present moment. I would argue that the first example is incorrect. If you want to emphasize that the thing you are seeing right now in the present moment is unbelievable I would say: “I wouldn’t believe it if I wasn’t seeing it with my own eyes” Best of luck mastering conditionals!

Instead of doing work I’d rather spend quality time with my children. I would like to prioritize my family on the weekend even I am wondering about the technology of my work. Instead of working, I would rather spend quality time with my children. I want to prioritize my family on the weekend, even though I’m still curious about the technology I work with. I’d rather spend time with my kids than work. On weekends, my family comes first, even if I’m still interested in the tech from my job.

Yes!

I went to work today. I was so busy and tired🫠 I want to take a very long bath. It is my favorite thing to do when I am tired, but my bathtub is a little bit narrow. I can't stretch my legs in it. It is a bad point of my house.

I met my friends that I have had since high school. They are very funny and kind, so I can talk to them about everything. For example, my concerns, my life and my wellbeing/ happiness. We had dinner together. I want to meet them again. We made a promise that we will meet again soon. I can’t wait!
