What is the passage mainly about
Careful reading
There was a strange stillness. The birds, for example - where had they gone Many people
spoke of them, puzzled and disturbed. The feeding stations in the backyards were deserted.
The few birds seen anywhere were moribund; they trembled violently and could not fly.
It was a spring without voices. On the mornings that had once throbbed with the dawn
chorus of robins, catbirds, doves, jays, wrens, and scores of other bird voices there was
now no sound; only silence lay over the fields and woods and marsh.
Silent spring.
What is the purpose of writing the book Silent Spring
Read paragraph 2 and answer the question.
Rachel Carson was a scientist by profession, but these lines from the opening chapter of
her 1962 book Silent Spring, “A Fable for Tomorrow”, show her talent as a writer. By
imagining a world without birds, she aimed to alert not only the scientific community but
also the general public to the damaging effects of human activity on natural ecosystems –
in particular, to the harmful use of pesticides, such as DDT. She believed that the
chemical industry was knowingly causing harm to plants, animals and even humans, and
wished to see pesticides used in a more responsible, limited and carefully monitored way.
To alert the scientific community and the general public to the damaging effects of human activity on natural ecosystems.
Read paragraph 3 and do the True or False questions:
Carson urged people to make themselves aware of the facts and do something about the situation. Silent Spring
contains a lot of scientific research and case studies. The book details the gypsy moth eradication programme,
which killed birds, in addition to gypsy moths. Another case study was the fire-ant programme that killed cows,
but not fire ants. The book also gives dozens of other examples of eradication programmes that did nothing to
reduce the problems they were originally designed to solve. The 50 or so pages at the end of the book list Carson's
sources, showing how thorough and precise she was as a scientist.

2. The book details many eradication programmes showing how thorough the precise she was as a scientist. ( )

F
The 50 or so pages at the end of the book list Carson's sources
Read paragraph 4 and choose the correct answer.
Carson's message was very alarming, causing a great increase in environmental
awareness. Its impact was immediate and far-reaching: the use of DDT was banned
and the Environmental Protection Agency (EPA) was established in the US. Silent
Spring was therefore regarded as a milestone in the launch of the green movement in
the Western world. It also earned Carson a posthumous Presidential Medal of
Freedom and put her face on the 17-cent US stamp.
Which of the statements about the impacts of Carson’s book is WRONG
She was regarded as a national hero.
The use of DDT was banned.
The EPA was established.
Her face was put on the 17-cent US stamp.
Under the attack of many people, Carson________.
A. gave up her opinion
B. sought support from the government
C. compromised with opponents
D. stood by her research
Read paragraph 5 and choose the correct answer.
Silent Spring was not, however, received positively by everyone. Though Carson's research was strong and was
supported by most scientists who reviewed her work, the book quickly became a target for critics in the pesticide
industry. They said that Carson did not understand the science behind her arguments because she was a marine
biologist rather than a chemist. Some also said that her work was more emotional than scientific. These were
attempts to damage Carson's reputation and stop her work from influencing public policy, but she remained
determined to stand by her research. Carson appeared in public and on television to defend her claims – and
today, more than 50 years after it was published, the voice of Silent Spring is still ringing loud and clear.
Read paragraph 6 and choose fill in the blanks. answer.
Personally, I enjoy Carson's book. She made a crucial but potentially difficult- to-
understand subject interesting and accessible to millions of people. This is not so
much because of the quality of her arguments, strong though they are, but because of
the beauty and elegance of her writing. Her book not only changed the world; half a
century later it remains a book that deserves to be reread today, so that we can once
again feel ourselves warm to the fire of its passionate message. For unless we do
listen to Rachel Carson's warning, one day we may wake up to the strange and quiet
horror of another silent spring.
The author compares the natural disaster to ___________.
The figure of speech is _________.
silent spring
metaphor
