In English, we use a lot of phrasal verbs. Let's see how they work using some examples from the story of the Ugly Duckling.

Sometimes it's hard to know how to pronounce the "-ed" ending of a regular verb in the past tense. Here are plenty of examples, taken from the story of the Ugly Duckling.

Sigrid shares what she has learned about having a swimming pool. As it turns out, having a pool is a lot of fun, but also quite a lot of work.

There are various things we need to do to keep the pool clean and the water circulating. Sigrid describes some of them. It's quite a lot of work, but she thinks that having a pool is still worth it.

In the first of three related lessons, we talk about the important and common word "point" as a noun in its most concrete form. We use "point" to talk about measurements, maps, numbers, and more.

In this lesson, we talk about the word "point" in its figurative sense, and as part of the phrasal noun, "point of view." In addition, we talk about verb, adjective, and adverbial forms.

In this lesson, we learn about the word "tip" and then we look at how it combines with "point" in the noun "the tipping point."

We can use dots and circles to describe things figuratively. Sigrid gives us examples with expressions like "connect the dots" and "inner circle."

A square is a shape, of course, but there are plenty of ways we use squares to describe things figuratively. Let's look at some examples of when and how we do this.

What expressions are related to the word "line"? We use "line" when talking about the laundry, behavior, or even time.

We use a combination of the five senses to understand what is happening around us. If one sense is weak or lacking, we compensate with another sense.

Although we use the passive tense in the present tense, it's used in other tenses, too, and that's what we look at in this lesson.

Here are some examples of sentences using both the active and passive voices. Different tenses are used, too!

What are causatives? Causal verbs are used to cause things to happen. They're used in causative constructions. Although there are various specific verbs in this category, we commonly use four ordinary verbs for this: ("have," "let," "get," and "make"). Let's make some sense of them.

Now that you have an idea about what causal verbs and causal constructions are, let's give them some context. We're still using the verbs "have," "let," "get," and "make," and the theme is housepainting.
