Acho que se perguntar em inglês, as pessoas podem entender melhor. 

Is there anyone available to help me with English? I can teach you Portuguese in exchange of learning English. 

Hey, there! I'm not native but I study English on a daily basis. I'm also looking for someone to practice. I think if you practice you will gain some confidence in speaking.

If you want to improve your Listening, I truly recommend listening to some podcasts, such as "All Ears English" and "BBC Learning English". And also, take notes about chunks, idioms and phrasal verbs and get used to them. You can incorporate on your speaking and writing. 

I still struggle with the pronunciation of some words. I usually go to forvo.com and listen to native's pronunciation then I try to speak and mimic them. 

If you don't mind to practice with another Brazilian, I'm in. 

Safe is an adjective and it means the audit is safe for usage and it's from a reliable source. The other one "safety" is a noun with a suffix (ty) in the end and it means the audit will be used for the user's safety.

I'm not native, but if does

I'm not native, but if does not matter, we could talk. 

One of the <strike>major</strike> main problems of modern Era  is related to health issues due to <strike>caused by</strike> a sedentary lifestyle. It became an important problem, as nowadays many jobs do not require any physical activities and <strike>mainly</strike> the daily work<strike>ing</strike> <strike>day</strike> consists of long hours in front of a computer. Thus, an inactive lifestyle has become more common and therefore there is <strike>we have</strike> a substantial increase in conditions linked to <strike>connected with</strike> it.

<strike>One of the most obvious negative effect</strike> A consequence of a sedentary life <strike>is</strike> could be obesity. Most people with deskbound jobs experience some <strike>kind of it</strike> degrees of obesity and with <strike>age</strike> aging the probability <strike>of</strike> to become obese can highly increase and also it <strike>becomes</strike> may be <strike>harder</strike> more difficult to return to a normal <strike>previous</strike> healthy condition.

Another <strike>thing,</strike> point is that being physically  inactive in your daily routine <strike>everyday life</strike> promotes heart-related problems. The excess of fat plus the physical inactivity can lead to the blockage of cardiovascular arteries <strike>because it causes blocking within arteries</strike>.

And finally, without regular exercises people lose <strike>in</strike> their muscle strength which can increase the possibility of many problems not only related to <strike>with</strike> physical performances, but also with joints and <strike>a</strike> bone structure. It makes their body feel weaker not only in terms of physical strength, but also in <strike>sustainability</strike> regard to other illnesses. So, regular sports activities could <strike>can</strike> increase lifespan and help people to become healthier.  <strike>live active life much longer</strike>.To conclude, a sedentary lifestyle has a<strike>n</strike> <strike>extremely</strike> negative impact <strike>effect</strike> on people's health and as nowadays many jobs are deskbounded <strike>table-bounded</strike> It has become a real issue <strike>As this</strike> leading to <strike>can promote</strike> <strike>various range</strike> plenty/plethora of illnesses <strike>diseases.</strike> On the other hand, people should compensate sedentary work with an active life out<strike>side</strike> of their workplace.
