I'll ask my dad to take us to the station. Would you mind taking us to the station, Dad?

Why is dad not capitalised in the first sentence but is in the second?

In the first sentence we use the personal pronoun my before dad. This shows we are talking about dads in a general way, and so we don't need to capitalise. In the second sentence Dad is the person's title. It's his name for now.

An important part of learning a language is to review words you have learned in the past. Sometimes we want to learn new words so much that we forget to go back any study the words we have learned before. The problem with this is we can end up forgetting words we thought we knew. How many times have you come across a word you remember seeing but can no longer remember what it means?

Choose the word that is being described in each sentence:

We use the negative prefixes un- / in- /im- /il- /ir-

For example:

John and James are brothers. John is reliable, you can trust him to do anything you ask. James, on the other hand, is unreliable, you cannot rely on him.

By adding un to reliable we change the meaning of the word to not reliable.
