The Present Perfect Tense and Prepositions

Hi everyone!

Today I'll give you an abstract about our two last classes.

First, the Present Perfect Tense.

We saw a video on the website "Inglês na ponta da língua", where the teacher Denilson Lima has explained some aspects about the differences between Past Simple and Present Perfect.

1) To use Past Simple we must to have an adverb of time.

Example: Mike broke his leg last week. (Here we emphasize the time when the fact has occurred).

2) To use Present Perfect we do not need to use a temporal adverb.
Example: Mike has broken his leg. (Here, the action of braking the leg is more important).

Note 1: In the Present Perfect tense, the action is done in the past but its  effects continues to happen at the present time.  So, 'Mike has broken his leg and now he can't play football with us'.
Note 2: The journalistic forms at newspapers, magazins, on tv or websites uses, as standard, the Present Perfect tense. Why? The stories that are told happened in the past, but its effects still going on when we read them.



Task 1:  Could you tell us other examples of those differences?




Second, Prepositions IN/ON/AT

Our last class was about the prepositions in-on-at. We saw a video on Small Advantages where Gavin has told us the differences between them.

IN: used when you want to say that something is INSIDE other space.
Exemple: The ball is in the box (It is into a box).
ON: used when you want to say that something is ABOVE a thing.
Example: The ball is on the box (It is upside a box).

When we talk about time, we have other possibilities
IN: used when we talk about a large period of time.
Example: In the 19th Century the italian people became an unified nation.
ON: used to explain days and months, with some precision.
Example: I was born on April 20.
AT: used to precise a short period of time.
Example: Our class is going to be on Thursday, july 5, at 2 p.m.

Task 2: Tell us about the exceptions that Gavin explained on the video!!


See you on next Thursday, july 5, at 2 p.m.
