It's coming. The torto. Hey, friends, youtube. quickly. Take shelter. Because in today's episode, we are entering the eye on the storm, that is the toronto zoom. The weather has many sides, sometimes cool, sometimes hot, sometimes pleasant and sometimes extreme, creating thunderstorms. Cyclone floods at a, and one of the most extreme, brutal and potens of weather, is a type of a2。a. Toronto, which is also known as twisters, are rapidly rotating columns of a that reach from a storm cloud to the earth's surface. And rental naos are formed. They are a brutal force to record with that can take part everything that comes on its way, causing massive destruction to the surroundings. It's because of this very nature of torito's that scientists have shown a keen interest in IT, but the formation of a toronto is so complex that scientists still don't completely understand IT as conditions that give rise to one tonnato does not necessarily be responsible for forming another one. But what we know so far is that a torto is formed under a powerful and big thunderstorm gold super cells. When cold, dry air moving from one direction meets warm moisture coming from another direction, IT creates instability in the atmosphere. And as the cold that is tense or avia IT slides down under the warmer and pushes IT upwards very fast, the faster moving APP begins to spin and roll over the slower win, creating an invisible orizondo spinning effect like a as the winds continue to build up, stronger and more powerful warmer spinning winds ticking upward, causing an updraft, and with an increasing momentum and speed, the spinning winds create or protect. Now the wind has enough energy to fill itself and eventually keep going to form a. And when the pointed part of the toronto touches the earth surface from the cloud, IT is often referred to as a time stone. And then IT goes and does what he does best, that is, destroy everything along its bob through your time. Did you know the duration of tornatore s and the distance they travelled varies? Most of the tories oes lost only less than ten minutes and travel around five to ten kilometers before before vanishing. But in some cases, however, they can last several laws and cross distances over hundred and fifty kilometers. Also, the tedious tonio ever recorded was in bangladesh in nineteen eighty nine, as IT sail through the tarka region of the country, more than twenty villages were destroyed and around one thousand three hundred people were killed.

Why can't we just use the simple past tense? And why does english have to always be so complicated? First, let's consider the following situation. I called you last night, but you didn't answer the phone. Why I, i'm sorry, I didn't hear the phone ring. I was taking a shower when you called. In this scenario, you must use the past continuous tense. You cannot use the simple past tense. And IT is wrong to say, I took a shower when you called, but why? Well, to really understand why, we must first understand a little more about the past continuous tense. The past continuous tense, also called the past progressive tense, is used to talk about an action that was happening at a specific time in the past. To make the past continuous tense, we use was or war, and the g form of the verb IT looks like this. Jessica was proud to seen the piano at three o'clock yesterday afternoon, or the children were playing on the slide when the bell ring. The first thing to understand is that if we are talking now, the action is no longer happening. IT is finished. IT is in the past, but the past continues. Tense tells us more IT tells us the action was happening at a certain time in the past. For example, Peter was watching T. V. At nine o'clock last night from this, we know that Peter started watching T. V at some point before nine o'clock and continued watching after nine. Therefore, at nine o'clock, Peter was doing the action. He was watching T. V. The past continuous tense also shows that an action was already happening for some time, and not just for a short moment. Therefore, we often use the past continuous tense together with the simple past tense to show that a shorter action, simple past tense, happen during a longer action past continuous tense. Have a look at this example. Bob fell while he was running in the park this morning. This sentence shows that the shorter action he fell happened during the longer action he was running. Running in the park is a long action because most people don't run for just a few seconds. They run for many minutes or much longer. So here we want to use the past continuous tense. However, when someone falls, IT is a very short action. IT only last for one or two seconds. So now we want to use the simple past tense for the verb fall, which is fell. IT would not make sense to say bob was falling while he was running in the park this morning. That would mean that he was slowly falling for the entire time that he was running. But that just doesn't make sense. Let's look at another example. Bath was doing her homework when her father got home last night. Which one is the shorter action and which one is the longer action? Of course, doing homework takes some time, so that's the longer action. When beth's father got home, he just had to open the door and walk in. That's a very short action. So in this sentence, we use the past continuous tense. Together with the simple past tense, we want to show that a longer action was happening. Bath was doing homework when a shorter action happened. Dad got home when trying to figure out, which tends to use, pay attention to the words when and while for clues. When we talk about actions in the past, we often use the simple past tense after the world win after the word while we usually use the past continuous tense. So we can say ryan was mopping the floor when the lights went out, or we can say the lights went out while ryan was mopping in the floor. Remember that these two sentences have the exact same meaning. They both show that the shorter action happened at some point during the longer action. In this situation, the shorter action most likely interrupted or stopped the longer action, because when the lights went out, ryan probably couldn't see in the dark and had to stop mopping. The same is true about the children playing on the slide. When the bell rang, the children probably had to stop playing and go back to class. Finally, we can also use while to say that two longer actions were happening at the same time. Ryan was talking on the phone while he was watching T, V. That's all for now. We hope you were paying attention while this video was playing. Good luck on your next quiz.
