Protected by presidential decree, the breathtaking mountainous terrain of the Yosemite Valley is now a national park, enjoyed by many human visitors, while still home to the wild creatures and stunning vegetation that has inhabited it for millennia / centuries.

What's the difference between disinformation and misinformation? And what about misleading information? Find out in this video.

Tommy heads off to a place that holds special memories for him. Later on, his prison habits make fitting into a family meal difficult, and his sister sends away his first visitor from the past.

Audio and video sources can be factual, and can be used as evidence, but they can both be doctored, too. When we don't have the facts, we might have hearsay, but can we trust it?

“Because We Can” is about tension in a relationship that has lost its way, but there's a determination to turn things around and make it work again. The song features on Bon Jovi’s twelfth studio album, What About Now.

Tommy’s sister, Viki, is taking a very active role in controlling his new life outside of prison. In his meeting with a new probation officer, he immediately makes a bad impression before promising her that he's determined to get his life back on track.

Ed reminisces fondly in a song about the time he spent living in the United States, and an English girl that he spent time with.

Molten granite was cooled and scoured by glaciers, forming Yosemite’s almost surreal landscape with its many remarkable rock formations. Black bears inhabit the park and emerge each spring from their hibernation, ready to begin a new cycle of life.

As spring arrives, the remarkable and deadly poisonous Sierra newt moves to its traditional aquatic breeding grounds. Meanwhile, kingfishers fish the crystal clear Yosemite streams and squirrels play a dangerous game of chase with the hunting bobcats.

Tommy has his first day at a very boring job that his parole officer set him up with. On the way home to his sister's house, he finds himself face to face with some old acquaintances.

Enigmatic Smiths frontman Morrissey and rock star David Bowie clearly enjoyed their duet on this live version of "Cosmic Dancer," which they performed as an encore after an LA concert. The song was written by Marc Bolen of the English glam rock band T-Rex.

After a decade of success in the music industry, American singer Miley Cyrus looks back at her past and the way she used to be with this introspective track from her eighth studio album, Endless Summer Vacation.

Modal verbs are special verbs that go together with action verbs to indicate ability, permission, obligation and more. Let's see how they work.

Tommy’s former associate is determined to recruit him, but his sister is against it, and shows Tommy something that she thinks might convince him to stay on the straight and narrow. Then a surprise sighting at the burger restaurant reveals that she has been misleading him about somebody close to his heart.

In the wooded valley, a pine squirrel falls prey to the voracious bobcat. Here we find some of the oldest and tallest trees on earth: The giant sequoias, which are now a major attraction for visitors to the park.

A relaxing bobcat family is surprised by the appearance of a young black bear. Elsewhere, a raven family is threatened by the presence of a bald eagle circling above their nesting site.

Every modal verb is a bit different and not all of them can be used in all tenses. We use "may" for permission, but we can use "can" and its conditional form "could" as well.

Tommy confronts his sister, who had told him that his girlfriend died while he was in prison. Christy is still very much alive, and Tommy, still in love, rushes to her apartment.

Kate lives in Grand Lake, Colorado, a small town that is considered the gateway to Rocky Mountain National Park. Kate’s friend Tom is inspired by the cold and recent snow to go out and take a plunge in the icy lake!

About her Eurovision-premiered song, singer Rosa Linn says, "I think we’ve all been at a snapping point, where it felt like there’s no way out and that the entire world is just crumbling down around you. You start questioning everything, including yourself..."

The imposing rock faces of Yosemite are very popular with sport climbers, and the rocky heights are also home to the endearing American pika. Mule deer, many with fawns, inhabit the lower valley, which is awash with spring color.

When do we use "should" and "could"? At the end of the video, you'll also find a preview of the next 2 videos where modals are used in everyday speech for discussing probability.

Enjoy another walk through the fields with pig brothers Piggeldy and Frederick. This time Piggeldy wants to know what a sheep is.

When Christy’s boyfriend shows up, Tommy is left in confusion and he needs to make a quick exit! He then has to visit the probation office, where at least he seems to be striking up a good rapport with his probation officer’s son.
