Let's fix the sentences for a 6-year-old
Two sentences you gave:
- 1) Electric rays use electric shocks to catch fish.
- 2) Electric rays shock fish to catch them.
Both sentences have a correct idea, but the first sentence is a bit clearer and gentler for young learners. The second sentence is also understandable, but it sounds a little bolder.
Here are simple, correct options you can use:
- Option A: Electric rays use electric shocks to catch fish.
- Option B: Electric rays shock fish to catch them.
Both options are correct. If you want to be very clear and gentle for a child, use Option A.
Tip for teaching: When you teach young children, use full sentences with clear subjects (Electric rays) and actions (use, shock). You can also show pictures of electric rays and fish to make it easier to understand.
