This is considered STEALING. She is stealing the words of another person and portraying them as her own.

The images below show a page from a 2013 article on climate change (left) and a paper written by Jin using two paragraphs in her paper from the article (right). The copied paragraphs are highlighted.
Jin does not properly cite the paragraphs. Instead, she includes the paragraphs as her own in her paper.
She steals them and is therefore plagiarizing.
Another way Jin could plagiarize is by writing her own sentences in between sentences in the paragraphs she copied.
The lines in yellow are the copied text.
