Connectors and Prepositions
Prepositions and linking words show where, when, and why things happen. This chapter reviews place and time prepositions and the connectors that join ideas of contrast and precaution in everyday situations.
Prepositions of Place
A specific point takes 'at' ('at the bus stop'), while 'in' suggests an enclosed space. Choosing the right one keeps location clear.
Prepositions of Time
Days take 'on' ('on Saturday'), clock times take 'at', and months take 'in'. These small words are easy to mix up but important for clear scheduling.
Contrast and Precaution
'However' shows contrast between two statements, and 'in case' explains a precaution for a possible event: 'I brought an umbrella in case it rains.'
