I am a new ESL teacher, and I would like some help to understand my student's error so I can better explain WHY it needs to be changed. I can't figure out the "rule" as to why it needs to change. Layman's terms are greatly appreciated if possible!
Here is what my student wrote, "He is working to keep clean and safe the Earth." I know it should be, "He is working to keep the Earth safe and clean," but I can't understand the rationale (or how to put it in kid-friendly terms for my ESL pupils).
Thank you in advance for your help!
