Use sleep for the action of resting and asleep for the state of not being awake. Use live for the verb of having a home or existing, and alive for the state of being living or not dead. Before a noun, use live when that is the meaning: a live animal.
Use so before an adjective or adverb: so quiet, so quickly. Use such before a noun phrase: such a quiet room, such helpful advice. With countable plural nouns and uncountable nouns, use so many or so much: so many messages, so much traffic.
Choose a subordinating conjunction that shows the relationship between your ideas, then join a dependent clause to a main clause. Use a comma when the dependent clause comes first: Because the roads were icy, we stayed at home. Usually do not use a comma when the main clause comes first: We stayed at home because the roads were icy.
Use should plus a base verb for advice: ‘You should save the receipt.’ Use could plus a base verb for a possible option: ‘You could ask the shop for help.’ Use why not plus a base verb or how about plus an -ing form to suggest an idea.
Choose a synonym by reading the whole sentence. Pick the word that keeps the same idea and fits the grammar and tone; do not choose a word only because it appears in a word list beside the target.
Use the statement's auxiliary verb and a matching pronoun in the tag. A positive statement usually takes a negative tag, and a negative statement usually takes a positive tag.
Wait for a natural pause, then use a short phrase that matches your purpose. Say "Can I add something?" to join in, "Just one more point" to hold your turn briefly, and "What do you think?" to pass the turn to someone else.
When you meet a new word, read the whole sentence first. Check its job in the sentence, notice a common word partner, and reuse it in a different but believable situation.
Use wanna only as an informal way to say want to, and use gonna only as an informal way to say going to for a future plan. They show relaxed speech, not standard spelling. Write the full forms when the situation needs standard English.
