Review Lesson 22

Hello! We have learned a lot in these last few lessons. Let us take a moment to review what we have learned.

First, we expanded our understanding of “would” and “could” by learning to construct “if-then” sentences. We learned to make sentences like "If I had a million dollars,(then) I would buy a lot of cars". In this sentence, the "if-clause", the first clause of this sentence, contains a verb which looks like the simple past tense and which conveys an unreal condition. The "then-clause" contains a modal conditional verb, which conveys an unreal, hypothetical result.

We learned that the modal "could" is a very versatile verb. The word "could" is the simple past tense of the verb "can", and it is also used in the "if-clause" of a hypothetical sentence. For example, we might say "If I can find my jacket, I will go outside." This sentence is a prediction. We can change it to an unreal hypothetical statement by changing the verbs, like this: "If I could find my jacket, I would go outside." This sentence means that the speaker cannot find his jacket and therefore will not go outside. It is an unreal hypothetical; it is not a prediction.

Then, we learned about the modal verb “should” and how it is used to give advice and make suppositions, and is used with the bare form of other verbs. Like the other modal verbs, the modal verb "should" does not change conjugations.

The modal verb "should" is also used to express a near-obligation, something we are supposed to do, but it is not absolutely necessary, as well as to express expectations based on past experiences. We can also use "should not" to make suppositions or express expectations.

Finally, we learned about comparative adjectives and how to form them. Comparative adjectives are used to compare the difference between two nouns. To form the comparative of these short adjectives, we simply add "er" to the end of the word. To form the comparative form of short adjectives ending in a consonant which follows a vowel, we double the consonantand add "er". To form the comparative of "pretty, easy, lazy," and other adjectives which end with a consonant followed by "y", we change the "y" to "i" and add "er". To form the comparative form of long adjectives and some short adjectives, we put the word "more" before the adjective.

Great! Now that you have reviewed each of these concepts, you have reinforced the knowledge you have learned thus far.
