1. Which f the abve aims have yu dne well?
I think I have achieved Gal A – understanding and explaining the cnnectins between things in nature and the imprtance f the balance f nature.
Everything in Nature Is Cnnected.
The sky, muntains, lakes, frests, grassland, and all the living creatures frm a great system, in which every thing cnnects with ne anther in an visible r invisible way.
Harms dne t any part f the system may lead t serius damages t the thers.
2. Hw d yu have a gd understanding f the cnnectins between things in nature?
Take the glbal warming as an example. If the temperature keeeps rising n earth, the icebergs n land wuld melt, which wuld directly damage the habitats f plar bears and penguins. S keeping the balance f temperature is very imprtant.
3. Which f the abve d yu still find difficult? Why?
I find it difficult t keep eye cntact with my audience while I am making a presentatin.
Because I am shy. My face will flush if I stare at smene fr a few secnds.
4. What d yu plan t d if yu find smething difficult?
Generally, I will sleep it ver if I find smething difficult. But if the next day I am still trubled by the same prblem, I will face the music.
