Researchers are beginning to understand why leaves sport it. Shelley poetically imagined that in autumn leaves lost their colour as the wild west wind drove them........... like ghosts from an enchanter fleeing... Well, that is one hypothesis. But it is unlikely to stand up to scientific scrutiny. And a surprising amount of such scrutiny is being devoted to the question of why trees turn such glorious colours. In deciduous woodland, the first signs of approaching autumn are written across the forest in shades of yellow and orange. Lower temperatures and shorter days trigger the breakdown of chlorophyll – the green molecule that captures energy from light in the process of photosynthesis. As the chlorophyll is removed, it reveals other pigments that have been swamped by its bold colour. These are called caratenoids. They aid the process of absorption and, in chlorophyll’s absence, give rise to pale and brilliant yellows, ambers, golds and oranges. Different species of tree retain different amounts of caratenoids, which leads to much of the polychromatic beauty of a forest in autumn. (Economist.com- PUC-RS) 1. The question that cannot be answered with the information given in the text is: a) Why do trees display different colors in autumn? b) What are the pigments responsible for the autumn colours called? c) What initiates the decomposition of chlorophyll? d) What is revealed by absence of chlorophyll? e) What elements compose the molecule of chlorophyll? 2. A palavra que pode substituir “As” (linha 1 grifada no texto) corretamente é: a) Wherever b) For c) Then d) When e) It 3. The expression “sport it” (line 2 underlined in the text) can be replaced in the context without a change in meaning by _____________. a) hold it b) play it c) leave it d) turn it e) wear it 4. ... “it is unlikely to stand up to scientific scrutiny” You understand that a) Nenhum escrutínio seria aceito por essa hipótese. b) Ninguém gostaria que um escrutínio científico fosse feito. c) É improvável que um cuidadoso estudo científico seja montado. d) Essa hipótese dificilmente passaria por uma investigação científica. e) Hipóteses desse tipo não são aprovadas para uma apuração científica. 5. In: “Lower temperatures and shorter days trigger the breakdown of chlorophyll”..., the underlined verb is closest in meaning to: a) avoid b) lessen c) cause d) prevent e) destroy Gabarito Comentado 1. Resposta e A pergunta que não pode ser respondida a partir da informação dada pelo texto é: “What elements compose the molecule of chlorophyll?” “Que elementos compõem a molécula de clorofila? 2. Resposta d As = when = quando “As autumn arrives...”= Quando o inverno chega... a)Wherever = onde quer que b) for = pois, para c) then = então e)It = pronome pessoal neutro da terceira pessoa do singular. 3. Resposta e – A expressão “sport it” pode ser substituída sem alteração de sentido por “wear it” = usar. No texto: “Researchers are beginning to understand why leaves sport it” (Pesquisadores estão começando a entender porque as folhas usam (vestem) vermelho.” a) to hold = manter b) to play = brincar, jogar, tocar c) to leave = sair, deixar, partir d) to turn = virar 4. Resposta d – “Well, that is one hypothesis. But it is a unlikely to stand up to scientific scrutiny”. *Bem, essa é um hipótese. Mas é improvável que resista a uma investigação científica. 5. Resposta c – *to trigger = to cause = causar, provocar *to avoid = evitar *to lessen = diminuir *to prevent = impedir *to destroy = destruir
