Get ready for another round of "Think Fast!" Sigrid will describe some objects and you have to figure out what each object is. Even if you don't know the word for it in English, you are still doing great if you can visualize the object being described.

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

What do people traditionally do on Memorial Day and Labor Day? Let's find out.

Sigrid talks about two important US holidays, Memorial Day and Labor Day. They are quite different in what they commemorate, but they're combined here because many Americans see them as bookends to the summer season.

This episode of "Think Fast" is dedicated to the summer and the heat. Try to guess what Sigrid is describing!

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.

What is the passive voice all about? Sigrid takes us through the basics, step by step. In the active voice, we focus on "who" does something and in the passive voice we focus on "what" someone does.

In this game, following the description is just as important, if not more important, than guessing the answer in English. Try visualizing what Sigrid is describing. You can also give yourself more time by hitting "pause" while the clock is ticking.

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.

In this video lesson, Luana has advice for avoiding arguments and fights, how to resolve them calmly and peacefully, and if necessary, express our apologies.

This segment is about the sense of smell and the sense of taste. When it comes to the five senses, every language seems to have some quirks, and English is no exception. For example, we use the same verb — "to smell" — to talk about perceiving an odor ("I smell the lemon") and giving off an odor ("The lemon smells delicious").

Every day, we get information from lots of different sources. But how do we know what is true and what is "fake news?" In this 3-part series we explore different kinds of information and misinformation.

The senses of sight, hearing, touch, taste, and smell are essential in experiencing the world around us. Let's consider them one by one and learn how to use them in conversation. We start with "sight" and "hearing."

Try to guess what word Sigrid is describing using the clues she gives you. Remember: You can always click "pause" if you need more time!
