2017屆高三英語Transforming Mars教案
in 1993 alone, over $109 billion was spent on pollution abatement and control in the united states.[6]however, many hazardous sites still remain. minimal research has been done to evaluate the health risks associated with chronic low-level exposures to hazardous substances, resulting in an inability to evaluate and manage such sites effectively and to evaluate the health status of residents living near such sites. further environmental epidemiology and toxicology research is needed to address such problems and to improve the science and public health management of the health effects on people exposed to environmental hazards.

寫作的訓練不一定要命題式的，過于格式化的寫作方式往往會扼殺學生的想象力和興趣，因此這里建議采用靈活隨意的方式鼓勵學生寫作。只要學生感興趣，效果就會很好， 學生豐富的想象力會令人感到驚訝的。最后，建議挑選好的作品編成小報展示。
1. 學生通過之前的活動，已被激發出保護地球的熱情，教師應趁熱打鐵使他們的激情得以表達。
2. 教師可以提供一些相關的詩歌網站來激發學生的靈感，幫助學生更好的完成任務。
詩歌欣賞：
our earth
the earth is ours to enjoy
for every little girl and boy.
but we must always be aware.
that all its beauty we must share
with all the children yet to come,
who want to laugh and play and run
around the trees and in the fields.
so we must keep our planet free
from messy trash and debris
with air that's clean and fresh and clear
for all to breathe from year to year.
we must never ever abuse
our sweet earth that's ours to use.
recycling in my home
(to the tune of "the wheels on the bus")
recycling in my home goes round and round,
round and round, round and round.
