1) I would say "I came here (got here) by Greyhound" and "I went there by Amtrak." You really don't need to use the verb ride because if the person you are talking to knows what Greyhound and Amtrak are, the fact that you rode is implied. If you want to use it, you can say "I rode the bus/train." 2) Both of those sentences work just fine.

You can say "...before you get married?".

writing exercise: First impressions

In my opinion, first impressions are crucial. Every person judges other people from the first look at them. What they wear, how they greet, how they behave and talk tell a lot about them from the very first minutes.
I think I'm quite good at understanding if one person is my kind of person. I'm also good at reading people's minds. This it makes me it easier to chose a person who may become a friend.
Obviously, sometimes I'm wrong. It has happened that the first impression was not the right one, particularly when the person is shy or introverted. That kind of person tends to hide and protect themselves by being quiet, not talkative. Only later in time, by hanging out with them, I got to know who they truly are: their opinions, their character, their values. Being an introvert myself makes it easier to recognize that kind of person.
On the other side, the shyness and being an introvert has made me miss some opportunities to get deeper in a relationship. So many times I avoided to put myself in situations where I could have felt embarrassed, and it was because either of the fear of being too intrusive or the lack of confidence.
In hindsight, I regret my behavior. If only I could turn back the hands of time, I would make different choices. I would try to be more open to new experiences and less scared of making mistakes and being misjudged by people.

Excellent writing!  Knowing when to use "person" or "people" can be tricky!

Essay 3: Clothing (part 4)

In sum, though some may disagree oppose this fact, many believe that different clothes influence our behavior. Not only will some clothes make us feel uncomfortable, but also they can also affect the way that others think about and behave toward us. So* every person should pay careful attention to his clothing.

*"So" usually isn't used to start a sentence.  Try "As a result, ..." or "Because of this, ...".  Great work!

Practicing my English

Hi guys! I'm here to practice my English conversation. If you are an English native and want to talk, I can help with Portuguese (Brazilian) too. :)

Hi Carolina, that's a nice and quick introduction. I know "practice" is almost the same in both our languages but look out for the "C" we have and you don't!

9/12/2016

Under the lovely morning sun, after the organizer brandished the flag in his hand and fired the starter pistol, the runners jostled each other and started to race towards the finishing line. I was one of them.
I ran as fast as my legs could carry me. The wind that brushed my face thrilled me. After a mile, I started panting; I felt my legs were heavier. More and more runners caught up to me, bypassed me and overtook me. One by one they disappeared from my eye-sight.
From the tar road, the route extended into a woodland, where the track became bumpier. The golden sunlight spilled through the slits between the leaves. A cacophony of insects and birds welcomed me into their territories. I was not in the mood to enjoy this. I lumbered through the woodland. I could feel my lungs were about to burst, and my legs were going to give way.
The track led me to a beach. The beach stretched like an undulating canvas with a trail of footsteps imprinted on it. At this time, I had no sight of  could see no other runners. Volunteers along the track cheered me up. My feet sank into the sand again and again and it was difficult to lift them up. I floundered along the beach. My body mass was pressing me down; I felt like I was walking on a high-gravity planet.
Finally, when I reached the finishing line, I realized I was one of the last persons who arrived. All the T-shirts were collected, except for XXL size, which is too big for my petite body.
I guess this is my last attempt at a marathon. I kept the oversized T-shirt for a souvenir.

Good job! You should be proud of your run - just finishing is more than most people can do.  Nice and descriptive writing, just watch out for words that should be plural.
