Modal Verbs Of Obligation

We continued on learning modal verbs. Second group we took was modal verbs of obligation. First of all we tried ourselves whether we know anything about modal verbs :


I had only 50%. For me it was a huge disappointment. But, anyway, I had a reason to study them and to complete homework properly. As usual we started with inventing rules. During last year I kind of got used to this approach of learning the usage of modal verbs or whatever in grammar. We completed exercise that helped us to invent rules. It was a simple bank of sentences with modal verbs. Our first step was analyzing them. You have to understand what does this sentence mean or what are author's intentions. Let's take as example sentence n3. "The map says you have to turn left here". Does the speaker express any opinion or emotion? - No. This sentences is usually used in GPS systems that never express emotions or opinion :D. Secondly, to understand, that this is another modal verb group (not certainty group) we have to analyze whether is there any probability expressed. -No. Last step is to understand necessity of completing this action. Is it necessary to turn left? -Of course. Otherwise you'll get lost!


Then we wrote down the rules. It was pretty easy to collect all-in-one.


Here you can also see exercises we completed during our topic. Here are some taken from classwork and some from homework.


Then we tried to understand whether it's an obligation or a necessity. For example modal verb "must" can express both. To understand the difference created bank of modal verbs, and completed some exercises. Let's take for example two simple sentences:
It must be her house.
You must think of your future! It's impossible to leave things the way they are now.

1st sentence expresses possibility. "It must be her house"- I'm wandering whether is it or not. I have evidence- I saw her entering this house yesterday. But still I it is PROBABLY her house. In this case we use "must" as strong supposition.
2nd sentence expresses necessity. You "must think of your future". This action has to be completed as soon as possible.


In last exercises we completed I had 90% correct answers. I think 40% progress a month is big achievement. I'm sure my classmates also have progress in modal verbs. But anyway, we'll see at the test. If you are interested in my final conclusion of learning modal verbs, you'll see it in chapter tests or in chapter reflections. I'm glad this system works )
