To talk about what you are able to do, or what is possible, use the English word can<\/span>.<\/strong> For things you are not able to do, or that are not possible, use can’t<\/span>. Can<\/span> is a special verb called a ‘modal verb’. This means it does not change its form for different subjects like I<\/span>, you<\/span>, he<\/span>, ou they<\/span>. You always use the base form of another verb (the infinitive without ‘to’) right after can<\/span> ou can’t<\/span>. Por exemplo, I can swim<\/span> means you have the ability to swim. She can’t fly<\/span> means she does not have the ability to fly. It’s a very common and useful verb for A1 learners to express abilities.<\/div>\n
