Step 1: General introduction:
The grammar items in this lesson focus on prepositional phrases. You are expected to learn that prepositions can be combined with verbs, nouns and adjectives to form prepositional phrases and the ways to use prepositional phrases in various situations. At the same time, you are expected to apply what they have learnt to practice by fulfilling some written tasks.
Step 2: Prepositions with verbs:
Some verbs in English are paired with a particular preposition to create an expression. Each of these expressions has a particular meaning. Even though there are often two or more prepositions paired with the same verb, each expression has a different meaning and they cannot be used interchangeably. For example, look at, look for, and look up have the same verb but three different prepositions. The phrases have different meanings and you cannot use look up when you need look for in your sentence.
