When you give advice using the imperative, the words are stressed normally:
"Eat an apple - it's much better for you than a biscuit!"
"Don't tell him you're resigning now! Wait until Monday when he's in a better mood."
You can often read articles in magazines that give advice on a subject. Sometimes, this advice is presented as "Dos and don'ts".
Do try to sleep well the night before
Do drink plenty of water
Do try to walk about the plane during the flight
Don't drink alcohol
Don't eat heavy meals
Don't wear restrictive clothing
You can also use the imperative to make a request, but you should use a polite word before the verb:
"Please take a seat."
"Please wait here."
"Please hold the line."
"Please don't smoke here."
In written English, you might also see "Kindly" used as a polite word:
"Kindly return the documents as soon as possible."
"Kindly forward this to the Sales and Marketing department."
"Kindly send me 2 copies of your brochure."
Using Lots of
In spoken English we often use lots of or a lot of. In written English, it is more common to write many (for countable plural nouns) or a great deal of (for uncountable nouns) in positive statements.
A common mistake is to use lot of. For example, "There are lot of accidents on this road". To avoid making this mistake, remember either to use a before lot, or to make lot plural - lots.
We can say either a lot of or lots of before a noun. For example, "There are a lot of people here" or "There are lots of people here". There isn't any difference between the two expressions.
We can also use a lot as an adverb to say how much you do something. For example, "She talks a lot".
A lot is also used in short answers. For example, "Do you like swimming?", "Yes, a lot."
