environmental awareness
Now work in pairs. Talk about which aspects of the book review make you want to read the book.
The influence of the book arouse my interest in reading the book. Because The book Silent Spring triggered an environmental movement and as such we have known the toxic effects of chemical agriculture, basically from the very beginning. We have suffered both massive environmental damage, disease and pest resistance, and human health issues.
Why was Silent Spring so successful
Silent Spring was so successful because it alerted the general public to the dangers of DDT. It planted important new ideas in the public mind, such as that spraying chemicals to control insect populations has an impact on other wildlife, and that the chemicals got into the food chain.
What is the moral lesson behind “A Fable for Tomorrow”
The moral lesson is that financial profit should not come at the expense of the environment and the creatures living in it.
Why did some people challenge Carson’s findings
Some people challenged Carson’s findings because they were concerned about the negative impact, they would have on business in the pesticide industry.
In what different ways do First Snow and Silent Spring raise people’s awareness of nature
First Snow shows the beauty of nature – and in particular the snow – through its words and imagery, while Silent Spring describes an unnatural spring without the beauty of birdsong. They each raise people’s awareness of nature by highlighting the interplay between nature and human behavior.
Post-reading
Work in groups. Write an award speech for Rachel Carson.
Read the passage again and make notes about Rachel Carson’s contributions to environmental protection. Consider the following:
her most influential work
what points she tried to make
difficulties she met with
her personal qualities
Rachel Carson received her Presidential Medal of Freedom posthumously in 1980. Read the excerpt from President Carter’s award speech and note the language features.
Never silent herself in the face of destructive trends, Rachel Carson fed a spring of awareness across America and beyond. Always concerned, always eloquent, she created a tide of environmental consciousness that has not ebbed.

Writing

Writing a poem about nature
Read the poems and tick the correct box(es) for each question.
□ Learning to learn
Rhyme is a typical feature of English poetry . A rhyme is a repetition of similar sounds（or the same sound）in two or more words. Children’s poems， called “nursery rhymes”，usually contain strong rhymes so they are easy to be remembered. In modern poetry，however，features other than rhyme are more important. Lines of modern poetry can be of variable length，the shape of the words on the page is more important，and rhyme is not often used.
Think about words and expressions related to nature and add them to the mind map.
sea：lots of fish，turtles，whales，sharks，dolphins，corals，seaweeds，crabs，etc.
mountains：tigers，wolves，foxes，bears，herbs，etc.
rainforest：birds，reptiles，etc.
grassland：lions，horses，antelopes，rabbits，snakes，elephants，etc.
lakes：lotuses，shrimps，clams，etc.
Work in pairs. Plan a poem. Consider the following：
what your poem will be about
what kind of poem you are going to write
what figures of speech you will use

There once was a boy who thought，
He could eat all the sweets he had bought.
