Science. Answers from Reality - Earliest Fire Sheds Light on Hominids by Nadja Neumann
You could travel back 790,000 years and still find someone to light your fire: archaeologists have collected evidence that early humans mastered fire much earlier than previously thought.
There is already good evidence for hearths that are 250,000 years old, and it was widely believed that the first controlled handling of fire occurred 400,000 to 500,000 years ago. But an analysis of burned remains carried out by Naama Goren-Inbar of the Hebrew University, Jerusalem, and her team now proves that fire was tamed at least 300,000 years earlier than that. The researchers have spent the past 15 years unearthing and sorting sediments at a site called Gesher Benot Ya'aqov in Israel. The site is of particular interest to archaeologists because it was an old crossroads between Asia and Eurasia. It is also waterlogged, which means that any ancient remains are extremely well conserved. The team sorted flint and wood from the 790,000-year-old site into burned and unburned material. They found that burned material made up less than 2% of the total and was concentrated at specific locations in the site, suggesting the fires that created it were started and controlled by early humans.
Goren-Inbar sees the study as a breakthrough in terms of understanding the evolution of hominids: the fact that they were using fire so early tells scientists a great deal about their abilities and behaviour at the time.
As well as providing protection against wild animals, fire would have enabled hominids to cook their food, stay warm during the winter and possibly improve their weapons. Chris Stringer from the Natural History Museum in London, UK, suggests that the use of fire would have enriched the hominids' social lives too. People may have gathered around camp-fires, staying awake longer and interacting more than before. He also points out that this first use of fire correlates with the time that hominids are thought to have entered colder areas such as Europe and Northern China, suggesting that fire helped hominids to explore environments that were previously too hostile. Goren-Inbar's analysis suggests that, as well as using fire, inhabitants of the site in Israel were collecting plant food, hunting and processing meat.
The team plans further analysis of the site's material to determine which species of hominid was responsible for the fires. Homo erectus, Homo ergaster and Homo sapiens were all around at the time, and all were able to walk upright, had large brains and were already using tools made of stone.

The Verb (I)
Tenses of the Indicative Mode
O clasa de cuvinte a carei importanta in vocabularul unei limbi se poate compara numai cu aceea a substantivelor este clasa de cuvinte care spune ceva despre un obiect (fiinta, lucru etc.), care exprima actiunea acestuia (to go - a merge; to make - a face), starea (to lie - a zacea; to sit - a sedea), transformarea (to consolidate - a se consolida; to weaken - a slabi), atitudinea (to like - a-i placea; to want - a vrea, a dori) etc. Aceasta clasa de cuvinte este denumita verb, atat in dictionare (vb, v) cat si in gramatici.
Ca parte de vorbire insa, ca element gramatical deci, verbul nu poate fi definit numai pe baza intelesului.
Gramatica trebuie sa tina seama si de forma verbului, de felul cum se asociaza cu alte parti de vorbire, precum si de functiile gramaticale pe care le poate indeplini in propozitie (sau, in general, intr-un context). Verbul este o parte de vorbire care denumeste actiuni, stari, aparitia sau modificarea unei caracteristici, transformari, atitudini etc., avand forme gramaticale caracteristice determinate de aspect, diateza, mod, timp, persoana si numar si indeplinind functia sintactica de predicat sau parte a predicatului.
THE SIMPLE PRESENT TENSE (PREZENTUL SIMPLU)
The Simple Present Tense uses the verb's base form (write, work), or, for third-person singular subjects, the base form plus an -s ending (he writes, she works).
Affirmative / Negative
I work / I do not (don't) work
You work / You do not (don't) work
He/she/it works / He/she/it does not (doesn't) work
We work / We do not (don't) work
You work / You do not (don't) work
They work / They do not (don't) work
Do I work? Do we work?
Do you work? Do you work?
Does he/she/it work? Do they work?
The Simple Present Tense indicates that an action is present, now, relative to the speaker or writer.
Generally, it is used to describe actions that are factual or habitual - things that occur in the present but that are not necessarily happening right now:
It rains a
It is raining in Portland. - which means that something is, in fact, going on right now.
I use my bike to get around town. - is in the present, but I'm not actually on my bike right now.
The present tense is used to describe events that are scheduled (by nature or by people):
High tide is at 3:15 p.m.
The Super Bowl starts at 6:15 p.m.
The present tense can be used to suggest the past with what is sometimes called
the fictional (or historic) present:
We were watching the back door when, all of a sudden, in walks Mary.
With verbs of communicating, the present tense can also suggest a past action:
Mary tells me that she took her brother to the dentist.
Most oddly, the present tense can convey a sense of the future, especially with verbs such as arrive, come, and leave that suggest a kind of plan or schedule:
Present tense habitual activities are frequently signaled by time expressions

time, never, etc.

THE PRESENT CONTINUOUS TENSE (PREZENTUL CONTINUU)
The Present Continuous (Progressive) Tense indicates continuing action, something going on now. This tense is formed with the helping 'to be' verb, in the present tense, plus the present participle of the verb (with an -ing ending):
I am buying all my family's Christmas gifts early this year.
She is working through the holiday break.
I am working / We are working
You are working / You are working
He/she/it is working / They are working
I am not working
You are not (aren't) working
He/she/it is not (isn't) working
We are not (aren't) working
You are not (aren't) working
They are not (aren't) working
Am I working? / Are we working?
Are you working? / Are you working?
Is he/she/it working? / Are they working?
The present continuous can suggest that an action is going to happen in the future, especially with verbs that convey the idea of a plan or of movement from one place or condition to another:
The team is arriving in two hours.
Because the present progressive can suggest either the present or the future, it is usually modified by adverbs of time. State verbs describe a continuing state, so do not usually have a continuous form. Typical examples are: believe, belong, consist, contain, doubt, fit, have, know, like, love, matter, mean, own, prefer, understand, seem, suppose, suspect, want, wish.
Some verbs have a stative meaning and a different active meaning. Typical examples are: be, depend, feel, have, measure, see, taste, think, weigh.
Compare these uses:
Jack is noisy. Jill is being noisy.
Mark has a Porsche. We are having an interesting conversation.
I think I like you! David is thinking about getting a new job.
This fish tastes awful! I am just tasting the soup.
I feel that you are wrong. I am feeling terrible.
This bag weighs a ton. We are weighing the baby.
It depends what you mean. I am depending on you.

a. Temporary or repeated actions
This use emphasises a temporary or repeated habitual action.
My car has broken down, so I am walking to work these days.
Are you enjoying your stay here?
b. Complaints about bad habits
You are always complaining about my cooking!

THE PRESENT PERFECT SIMPLE TENSE (PREZENTUL PERFECT SIMPLU)
The Simple Present Perfect Tense is formed with a present tense form of 'to have' plus the past participle of the verb (which can be either regular or irregular form).
I have worked / We have worked
You have worked / You have worked
He/she/it has worked / They have worked
I/you have not (haven't) worked
He/she/it has not (hasn't) worked
We/You/They have not worked
Have I worked?
Has he/she/it worked?
Have we/you/they worked?
This tense indicates either that an action was completed (finished or 'perfected') at some point in the past or that the action extends to the present:
I have walked two miles already. (but I'm still walking).
I have run
The critics have praised the film 'Saving Private Ryan' since it came out. (and they continue to do so).
FOR / SINCE
For and since are used with perfect tenses to indicate length of time.
Since can also be used with the Past Simple. Since refers to a date in the past and is used to talk about things happening between then and now.
For refers to the period of time that has passed between a point of time in the past and now.
I've known Mary since March.
I've known Mary for three months. (It is now June.)
Since can also be used in the middle of sentences which begin with a time period:
It's a long time since I've seen you. (I haven't seen you for a long time).
Since + Past simple:
It's two years since I left the army. (I left the army two years ago - finished action in
With adverbs beginning in the past and going up to present, we would use the present perfect:
I have studied up to now/lately/already.
We tend to use the Present Perfect when reporting or announcing an event of the recent past:
