Time prepositions
Prepositions are small grammatical words that usually go before nouns and pronouns. There are many different prepositions that are used to describe where things are, how things happen and when things happen, for example. In this Grammar Challenge we focus on the prepositions we use with certain time expressions.
| At – for times of the day | at half past 7 at midnight at sunset at breakfast time |
On - for days and dates | on the 5th of June on Tuesdays, on Saturday morning on Christmas day |
In - for longer periods of time | in April in 1987 in the winter of 1976 in the 1930s
|
| No preposition – for some time words | next last tomorrow yesterday |
Used to / didn't use to
When talking about things that we did in the past but don't do now we can use the expression used to. The negative form, to talk about things which we didn't do in the past but do now, is didn't use to.
| Positive sentences | I used to smoke 20 cigarettes a day. I used to eat loads of junk food. |
| Negative sentences | I didn't use to do any exercise. I didn't use to swim very well. |
All pronouns take used to / didn't use to | I You She He It We They | used to / didn't use to | eat a lot of sweets. eat meat. live in the city. have long hair.
|
Used to and didn't use to are only used to talk about past habits. There is no present form. To talk about present habits we can use the present simple. When using these structures there are often two parts to the sentence, something about the past and something about the present, for example:
I used to drive to work but now I go by car.
I didn't use to like coffee but I love it now.
Continuous Passives
This week, we're continuing our discussion of passives with a look at
continuous passives.
here are four main elements to a continuous
passive sentence: the 'passive
subject', the
verb 'to be', the word 'being', and the
past participle of the verb.
Present continuous passive
| passive subject | 'to be' | being | past participle | |
| The bridge | is | being | painted | this year |
| The interviews | are | being | held | in the office |
Past continuous passive
| passive subject | 'to be' | being | past participle | |
| The bridge | was | being | painted | last year |

Simple Passives There are three main elements to a simple
passive sentence: the 'passive
subject', the
verb 'to be' and the
past participle of the verb.

Because / because of
Do you ever get confused over when to use
because and when to use
because of? Well, help is at hand in today's episode of grammar challenge! Taka from Japan is up for the challenge... but are you?
Because and

verb.
Because of is a
preposition, and is followed by a
noun phrase or verb-ing

'Need + verb-ing'
Sometimes it's useful to talk about fixing or improving things, but without saying who is going to do it. To do this, we can use
need + verb-ing. To talk about fixing or improving things, you can use
need with an
-ing verb. There are three parts to this structure. First, you name the thing – my hair, or the car, or my shoes. Then you say 'need' - or 'needs' - and finally, a
verb with –ing.
Positive | subject | need(s) | verb-ing |
| My hair | needs | cutting |
| The curtains | need | washing |
Negative| subject | doesn't / don't | need | verb-ing |
| My hair | doesn't | need | cutting |
| The curtains | don't | need | washing |
Question| do/does | subject | need | verb-ing |
| Does | my hair | need | cutting? |
| Do | the curtains | need | washing? |
Uncountable nouns
English learners of all levels sometimes struggle with countable and uncountable nouns. Although most people understand that 'water' and 'bread' are uncountable, how about 'advice', 'equipment', 'luggage'...?
Nouns are usually countable or uncountable. Numbers, plurals and the articles 'a' and 'an' are NOT normally used with uncountable nouns.
| accommodation | equipment | information | patience | rubbish |
| advice | furniture | luggage | pollution | weather |
