When we want to form a past tense verb we usually add d or ed to the end.

We add d to verbs that end in a vowel:

Like becomes liked.

we add ed to verbs that end in a consonant:

Walk becomes walked.

Simple isn't it? Well, it should be but it isn't because English has many irregular verbs which refuse to follow this rule!

Generally, we use at, in and on when we talk about the location of things.

What do the prepostions in these three things tell us about the locations?

"Meet Simon at the end of the road."
"You left your glasses in the bathroom."
"Is that a spider on the wall?"

See, look and watch are all verbs that relate to our eyes, but what's the difference between them? Let's take a look at these words in context:

Look at that bird!

Did you see that bird?

This morning, I watched a bird eating the food I left in my garden.

How do you give your opinion on something? Is by starting a sentnce with "I think..."? This expression is fine but let's build your vocabulary by looking at other expressions we also use when we want to share our views.

It might be because the words are pronounced similarly that then and than are often confused by English learners. Let's take a look at the difference.

Then

Then is used either as a time expression, as a consequence or with a sequence of events.

Then Examples:

As a time expression - Sorry I missed your call last night, I was already sleeping then.

Do and does are used when we want to ask yes/no questions.

We use do or does depending on the subject. Below are two sentences with two different subjects, she and you.

Does she like sport? Yes, she does.

Do you like sport? Yes, I do.

English learners get confused about when to use bring and take. It is important to know that they do NOT have the same meaning.

To show you how confusing it can be, take a look at these two sentences, both of them are correct:

Relative clauses are used to give extra information about something in a sentence.

There are two types of relative clauses, defining and non-defining.

Defining Relative Clauses

A defining relative clause gives information about the noun it modifies.

The boy who lives next door loves tennis.

"My father taught me how to sail a boat."

"There's a great sale on in the department store."

Sail and sale have the same pronunciation although they are spelled in different ways – and have different meanings.
