Reading text

A new study published in the journal Science shows definitive evidence of organic matter on the surface of Mars. The data was collected by NASA's nuclear-powered rover Curiosity. It confirms earlier findings that the Red Planet once contained carbon-based compounds. These compounds – also called organic molecules – are essential ingredients for life as scientists understand it.

The organic molecules were found in Mars's Gale Crater, a large area that may have been a watery lake over three billion years ago. The rover encountered traces of the molecule in rocks extracted from the area. The rocks also contain sulfur, which scientists speculate helped preserve the organics even when the rocks were exposed to the harsh radiation on the surface of the planet.
Scientists are quick to state that the presence of these organic molecules is not sufficient evidence for ancient life on Mars, as the molecules could have been formed by non-living processes. But it's still one of the most astonishing discoveries, which could lead to future revelations. Especially when one considers the other startling find that Curiosity uncovered around five years ago.
The rover analyses the air around it periodically, and in 2014 it found the air contained another of the most basic organic molecules and a key ingredient of natural gas: methane. One of the characteristics of methane is that it only survives a few hundred years. This means that something, somewhere on Mars, is replenishing the supply. According to NASA, Mars emits thousands of tons of methane at a time. The level of methane rises and falls at seasonal intervals in the year, almost as if the planet is breathing it.
NASA suspects the methane comes from deep under the surface of the planet. The variations in temperature on the surface of Mars cause the molecule to flow upwards at higher or lower levels. For example, in the Martian winter the gas could get trapped in underground icy crystals. These crystals, called clathrates, melt in the summer and release the gas. However, the source of the methane is still a complete mystery.
The world of astrobiology considers both of these studies as historical milestones. According to this information, Mars is not a dead planet. On the contrary, it is quite active and may be changing and becoming more habitable.
Of course, this means further research is necessary. Scientists say they need to send new equipment to Mars, equipment that can measure the air and soil with more precision. There are already missions underway. The European Space Agency's ExoMars ship lands in 2020 and will be able to drill into the ground on Mars to analyse what it finds. Additionally, NASA is sending another Mars Rover in the same year to collect samples of Martian soil and return them to Earth.
The possibility of life on Mars has fascinated humans for generations. It has been the subject of endless science-fiction novels and films. Are we alone in the universe or have there been other life forms within our Solar System? If the current missions to the Red Planet continue, it looks as if we may discover the answer very soon.

yes, one day it is possible that people will live on Mars. Scientists work very hard and it is possible to stay on mars in the future.

This is endless topic. The people are brain washed by media which means hollywood movies etc. It is unbelievable that people will live on Mars for the next 100 years. There are two main problem. First one is economical problem that means live on mars is require too much expense. Second is scientific advancement that means our technology development too far from live on Mars.

Yes, I think one day we will live in Mars. There is too much discovery about this planet. I can imagine that we will live one day. Many private organisations are doing great things about space.
I'm not sure when it happened but many scientists do hard work on it.

Well, it's hard to imagine from now will people live on Mars or not. But I believe in human persistence and I read Andy Weir's novel "The Martian", so ... if we still will have potatoes and Mark Watney it may be possible. Jokes aside, I think we can do it. Seriously. All we need are time, desire, and money. The other question - why we should? I mean, just leave our scientist-guys aside (they definitely want that desperately) and try to answer the question - "What we are trying to find there?" Something valuable? Gold, platinum, diamonds? Do we really need them so much to spend such a huge amount of money to reach Mars? Maybe we should have another look at our home planet? Maybe we need first of all to take care of the blue planet before heading the red one? Clean all garbage we made, return the forests, stop killing wild animals, finally win poverty and starvation, and of course, all this "Mars money" can be spent to fight deadly diseases. I'm sure, before leaving home we need to check is it all right here?

I think that yes, someday people will live on mars but though it seems like science is doing a great job and is advancing quickly, the live on Mars like we live here on earth are far away. there are many challenges to surmount yet. I think that there are many secrets to discover about that planet. The future is so unpredictable that when I think about it, it blows my mind about the weird and interesting that could be.

A new rover landed on Mars a few days ago and send some videos and pictures to the earth. Also, it did an excavation. But it has not shown any sign from alive creatures. The speed of human progress in all sciences is high. Astrobiology is no exception to this. So yes, I think humans not only will live on Mars one day, but they will conquer other planets as well. The scary part of the story will start somewhere that inhabitants of the other planets will defend from their planet and it will make an Interplanetary war. And we don't understand their power yet.

Hello, I came here looking for some advice. I've noticed that while completing task 2, I tend to use very primitive variants of the given words. I've also noticed this in my day-to-day life, as I constantly use the same words and I feel like my English is starting to become very dull. I would really appreciate any help as the English language has recently become very crucial for me and for what I do. (By the way, should I be asking this question at other exercises, namely speaking and/or writing?) (My vocabulary is probably more advanced than usual, but that's because I am trying my best. The reason I am requesting advice is because I want to speak using good vocabulary without taking up too much effort.) Thanks Mounes

Hello Mounes,

There are many different ways you could do this, and I'd encourage you to experiment with different methods to see which work best for you. But for a start I'd recommend first identifying some words and phrases that you'd like to use more. You could find these by listening to what other people say or reading what they've written -- listen or look for words and phrases that impress you or that you think would be useful.

Make a list of 6–10 such words and phrases and, if possible, write out the sentences you heard or saw them in. You could then look them up in a dictionary to see how they are used in other contexts and thus get a better sense for what they mean and how they are used. A collocations dictionary could be particularly useful for this.

Then give yourself a week or so to try and use these phrases in your speaking and writing. If you can't find a situation to use them in your natural life, you can imagine one and speak to yourself or write about it.

Then repeat this process with a new set of words. As you do this, be sure to revise the words and phrases in your past lists so that you have a better chance of remembering them.

I hope this helps you. We'd love to hear how you get on with this.

All the best,

I think the writer should say that A new study is published instead of saying "A new study published". Also he should say that in 2014 it found the air contain instead of "in 2014 it found the air contained".

Hello mxoubi0,

I'm afraid that neither of your suggestions is correct. 'A new study published' is a reduced form of 'A new study that was published' and adding 'is' would conflict with the verb 'shows' as the sentence is written.

As for the second phrase, 'it' refers to the rover and 'that' is left out: the rover found that the air contained methane.

Hope that helps you make sense of these two sentences. By the way, we check our articles multiple times before publishing them, so usually they are correct. Occasionally a mistake does get through, but for the most part you can trust that they are correct!

All the best,

Do you think people will live on Mars? Apparently, Mars seems not suitable for Human habitat in the current state. Human can't breath in the air. Mars emits thousands of tons of methane at a time, quoted the article. Inhale the excess amount of methane usually leading to unconsciousness or death. Is it any future technology can change the atmosphere in the Mars? I hope so. On the contrary, if we cannot change the atmosphere in Mars, we better evolve our physical body to adapt the condition in Mars. I don't think people will live in Mars in today technology, but I do believe there are opportunity for our technology growing up rapidly after thousand of years. I would say people may live in Mars in the unknown future!

I have a doubt; in paragraph 3 of this reading, shouldn't it be FINDING instead of FIND ("the other startling find that... ")?. Sorry if it is a silly question but I am still learning. Thank you!

Hello Rinaclau,

It's not a silly question at all! Both finding and find can be used as nouns, but there is a difference. Finding is used for the results of experiments and surveys, while find is used for physical discoveries. Thus, a medical researcher reports some interesting findings, but an archeologist announces an exciting find.


In the context of the text, find is used because the rover discovered something in the air with a physical existence: methane molecules. Of course, since these were also discovered through running tests, you could use finding here as well.

How query and result belong on that word which are not belong?

Hello Rowshon Ara,

The four words in the question are data, query, evidence and findings.

Query is the odd one out because it is a kind of question. The others all describe results of experiments or research, so they are the answers you get.

Yes. Since, it's quite active, changing and becoming more habitable.

Submitted by Jana Ahmed on Fri, 03/04/2020 - 17:24

I don't really understand the difference between those words: periodically repeatedly consistently frequently Can anyone please point it out?

Hello Jana Ahmed,

Frequently tells us that something occurs often.


Periodically tells us that something occurs at regular intervals (every day, every year, every decade etc).


Consistently is usually used with reference to people and it tells us that their behaviour is not random or changeable, but rather follows a predictable pattern in line with expectations.


Repeatedly tells us that something happens more than once. It is often used to show irritation at a lack of response: I've repeatedly asked for help but you ignore me.



The LearnEnglish Team

consistently is the way that does not change periodically, repeatedly, frequently are repeated many times or show that a thing often happens

As the text itself paraphrases, the fact that these traits have been found in this place doesn't necessarily mean, however that is certain to a certain extent that we have any possibility to live there. Then, if by any chance we happen to find out that the planet has the suitable conditions in order for us to live there, we would still need to figure out how to arrange everything in such a way that it satisfies our average needs which certainly would take quite a long to devise, not to mention the fact that it still happens to be the space, for instance the atmosphere in Mars is not suitable for humans to be able to breathe here let alone put up with the outrageous effects that it has on human body. Hence, in the meantime I'm afraid answer will still remain unclear.
