🔗2. A lot of and lots of

□These are rather informal. There is not much difference between a lot of and lots of. They are both used mainly before singular uncountable and plural nouns, and before pronouns. When a lot of/lots of is used before a plural subject, the verb is plural.
◇A lot of my friends live abroad.
◇Lots of time is needed to learn a language.

🔗3. Plenty of

□Plenty of means enough and more. It is used before singular uncountable and plural nouns.
◇There is plenty of time.
◇Plenty of shops accept credit cards.

🔗4. A large amount of, a great deal of and a large number of

□These expressions are rather formal. A large amount of and a great deal of are generally used before uncountable nouns.
◇She has spent a great deal of time in Europe.

○A large number of is used before plural nouns. The following verb is plural.
◇A large number of issues still need to be addressed.

🔗2. Not only --- but also

○This is a relatively formal structure. When you use this structure don’t forget to put not only and but also before the words or expressions that they modify. Also make sure that the structure is parallel.
◇He was not only a great singer but also an accomplished pianist.
◇I was not only upset but also angry.
◇He not only misbehaved with the servants but also broke the windows and furniture.

🔗3. Not only can be moved to the beginning of the sentence for emphasis. It is then followed by auxiliary verb + subject. If there is no auxiliary verb, we use do / does / did.

◇Not only did he misbehave with the servants, but he also broke the windows and furniture. (NOT Not only he misbehaved with --)

○But can be left out in this case and then we separate the two clauses with a semi-colon.
◇Not only did he misbehave with the servants; he also broke the windows and furniture.

◇He got his article published. He also won an award.
◇She is a doctor. Her husband is also a doctor.

◇Meera is hard-working. She is also quite ambitious.
◇I want to buy a pair of trousers. I also want to buy a shirt.

◇When also refers to the whole clause, it goes at the beginning.
◇I am not about to buy this house. It is small. Also, it needs a lot of repairs.

◇She not only sings; she also plays the piano.
◇She not only sings; she plays the piano as well.
◇She not only sings; she plays the piano too.

●We do not normally use also in short answers and imperatives. Instead we use as well and too.
◇'I have a headache.' 'I have too.' (BUT NOT I also have.)

●In an informal style we use 'me too', instead of I am too.
◇'I am going home.' 'Me too.' (More natural than 'I am too.')
