Listening Summary : Artificial Gills - enabling human to breathe in the water

We all know that all living creature needs oxygen. When it comes to human, they could not breathe under the water, and sometimes drown in the water. For that reason, several scientists is in an effort to invent a device which enable human to breathe under the water for a long time. The former breathing apparatus, called scuba, is painful and heavy. So that, they need a device that can extract oxygen directly from water while swimming, and comfortable to use. The artificial gills, is the solution for this problem. To create an artificial gill, we need to find fragile material with big surface area, and we also need tiny tubes and valves to enabling divers to breathe. The imperative step is that we should keep the water move. The speaker, had created her own artificial gills and tried it in the swimming pool, and she can breathe for 45 minutes. In the future, the speaker believe that the device has a great potential in marine area.

... all living creatureS needs oxygen

1. CREATURES ---> it must be plural because you said "all living creatures" which means it is more than one type of crature

2. Creatures===> need (without S)

Overall you just make a tiny mistakes, keep hard work and break a leg !

Hello, I give my correction for you

all living creature creatures needs need oxygen ("all" indicate the plural noun, so you must write "creatures" and use singular verb "need")

several scientists isare in an effort (the subject is plural, so you must use plural verb too)

the speaker believebelieves(remember the subject "the speaker" is singular)

thank you

Hello here my advice for you.
several scientists is in an >> PLURAL NOT SINGULAR (using are not is)
creature needs >> your word not appropriate for that sentence, (creatures need)
The artificial gills, is the solution for this problem > are not is

your writing is quite good, but many wrong grammatical, particularly using plural and singular.

Dear Nda
Here, my corrections toward your writing

For that reason, several scientists is in an effort to invent ...
>>> several scientists carried out the ambitious project to invent a technology device which enables a human to air in and out of lungs although in the sea.

note: you wrote every single sentence perfectly, you used word connector properly while you used varied vocabulary. Furthermore, although you provide the brief explanation, it provide us with an array of information. However, you have to notice to your writing whether your sentence already provided and showed enough information before you are going to explain other topic
