SIMULADINHO Although robots have made great strides in manufacturing, where tasks are repetitive, they are still no match for humans, who can grasp things and move about effortlessly in the physical world. Designing a robot to mimic the basic capabilities of motion and perception would be revolutionary, researchers say, with applications stretching from care for the elderly to returning overseas manufacturing operations to the United States (albeit with fewer workers). Yet the challenges remain immense, far higher than artificial intelligence obstacles like speaking and hearing. “All these problems where you want to duplicate something biology does, such as perception, touch, planning or grasping, turn out to be hard in fundamental ways,” said Gary Bradski, a vision specialist at Willow Garage, a robot development company based in Silicon Valley. “It’s always surprising, because humans can do so much effortlessly.” http://www.nytimes.com, July 11, 2011. Adaptado 1. Segundo o texto, um grande desafio da robótica é: a) não desistir da criação de robôs que falem e entendam o que ouvem. b) melhorar a capacidade dos robôs para a execução de tarefas repetitivas. c) não tentar igualar as habilidades dos robôs às dos seres humanos. d) voltar a fabricar robôs que possam ser comercializados pela indústria norte-americana. d) projetar um robô que imite as habilidades básicas de movimento e percepção dos seres humanos. 2. De acordo com o texto, o especialista Gary Bradski afirma que: a) a sua empresa projetou um robô com capacidade de percepção. b) os robôs já estão bem mais desenvolvidos, atualmente. c) a construção de robôs que reproduzam capacidades biológicas é difícil. d) as pessoas podem ser beneficiadas por robôs com capacidade de planejamento. e) a habilidade das pessoas em operar robôs sofisticados é surpreendente. One Man in a Boat Fishing is my favorite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything – not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. “You must give up fishing!” my friends say. “It’s a waste of time.” But they don’t realize one important thing. I’m not really interested in fishing. I’m only interested in sitting in a boat and doing nothing at all! LIBERATO, W. A. Inglês doorway (Coleção Delta). 3. Embora o homem pesque com frequência, ele: a) só pega botas velhas e lixo; b) sempre pega lixo; c) nunca pega coisa alguma; d) às vezes pega um peixe; e) só pega sacolas velhas. 4. Os amigos dele costumam dizer que: a) um dia ele será um bom pescador; b) ele tem de desistir de pescar; c) ele deve continuar tentando; d) ele precisa se esforçar mais; e) ele é um homem de sorte. 5. Em “Fishing is my favorite sport” a palavra fishing é um: a) verbo b) adjetivo c) advérbio d) substantivo e) conjunção A wave of anger is sweeping the cities of the world. The protests have many different origins. In Brazil people rose up against bus fares, in Turkey against a building project. Indonesians have rejected higher fuel prices. In the euro zone they march against austerity, and the Arab spring has become a perma-protest against pretty much everything. Yet just as in 1848, 1968 and 1989, when people also found a collective voice, the demonstrators have much in common. In one country after another, protesters have risen up with bewildering speed. They tend to be ordinary, middle-class people, not lobbies with lists of demands. Their mix of revelry and rage condemns the corruption, inefficiency and arrogance of the folk in charge. Nobody can know how 2013 will change the world – if at all. In 1989 the Soviet empire teetered and fell. But Marx’s belief that 1848 was the first wave of a proletarian revolution was confounded by decades of flourishing capitalism and 1968 did more to change sex than politics. Even now, though, the inchoate significance of 2013 is discernible. And for politicians who want to peddle the same old stuff, news is not good. The Economist, June 29, 2013. Adaptado. 6. Ao comparar os protestos de 2013 com movimentos políticos passados, afirma-se, no texto, que: a) nem sempre esses movimentos expressam anseios coletivos. b) as crenças de Marx se confirmaram, mesmo após 1848. c) as revoltas de 1968 causaram grandes mudanças políticas. d) mudanças de costumes foram as principais consequências de movimentos passados. e) não se sabe se os protestos de 2013 mudarão o mundo. 7. De acordo com o texto, após usar o Facebook, algumas pessoas: a) se sentiram insatisfeitas b) fizeram mais amigos c) questionaram umas as outras d) completaram rapidamente suas pesquisas científicas e) se sentiram muito felizes 8. Complete o texto com a palavra apropriada. a) many b) some c) much d) a few e) no Henry James is one of America's greatest novelists, and the author of The Turn of the Screw, a well-known short ghost story, published in 1898. It is a story that many people have made into films and operas. One of the best operas is one written by Benjamin Britten in the mid twentieth century. The book is about a governess who looks after two children in a house which has no near neighbours. The story is both haunting and frightening. The children, Flora and Miles, are charming to their teacher, but when she starts to see the figures of a man and woman in the gardens, she begins to believe that supernatural forces possess them, and will lead to their destruction. The reader and the listener sometimes wonder if the governess is mad, because both author and composer cleverly leave a lot of room for the reader’s / listeners’ own terrible thoughts and ideas. Ghost stories and music have a similar effect on us. The best ghost stories try to get into our minds, and music has the power to go past our conscious thought and appeal directly to our feelings and emotions. So the terrifying production that opened last night at Covent Garden Opera House is successful for two reasons: first because it has a great author and composer, and second because your imagination takes over from your sensible mind. 9. Decide if the following statements are True or False according to the text and choose the correct alternative. I. The story takes place in a haunted castle. II. Henry James and Benjamin Britten worked together in The Turn of the Screw. III. The story first appeared in a book. a) F F T b) T T F c) T F T d) F T F e) T T T 10. How are ghost stories and music similar? a) Both of them are scary. b) Both of them make us cry. c) Both of them are part of an opera. d) Both of them are written by the same person. e) Both of them appeal to our feelings and emotions.
