Winter s por ts

Only two areas of the USA are mild in winter, the coasts, especially Florida and southern Californ ia, and the southern part of the Mississippi basin.

Everywhere e lse it gets cold, often very cold. By the end of November, many Ame rican states are often covered in snow; and although recent winters have been less cold, sport in winter usually means winter sports, or indoor sports.

By January, many people in North America will have temperatures of -30°C; not every day, of course, but such low temperatures are not rare. In Chicago and Minneapolis, the temperature can fall below -40°.

When it is very cold, especially when there is a cold wind, people want to go outside, unless they have to; but on sunny winter days, winter sports are popular.

In the large flat regions in the middle of No rth America, winter sports are snowmobiling, snowshoeing and cross-country skiing. Ice-skating is popular too; lakes and rivers freeze, and many towns and cities have free open-air skating rinks. In many places, these are flood-lit after dark, so that people can enjoy skating in the evening.

Chega de Saudade – texto adaptado – (Vinícius de Moraes)

Vai minha tristeza
E diz a ela que sem ela não pode ser
Diz-lhe numa prece
Que ela regresse
Porque não posso mais sofrer
Chega de saudade
A realidade é que sem ela
Não há paz, não há beleza
É só tristeza e a melancolia
Que não sai de mim
Não sai de mim
Não sai
Mas, se ela voltar
Se ela voltar
Que coisa linda!
Que coisa louca!
Pois há menos peixinhos a nadar no mar
Do que os beijinhos que darei na sua boca [...]

Na canção, o uso da conjunção adversativa marca uma mudança significativa, do ponto de vista semântico, de estado de ânimo do eu lírico. Marque o trecho que exemplifica essa mudança.

Germanwings and its parent company, Lufthansa, are still reeling from the disaster. Senior managers are facing a barrage of questions about Lubitz and the company's policies.

Lubitz passed his annual pilot recertification medical examination in summer 2014, a German aviation source told CNN. An official with Lufthansa said that the exam only tests physical health, not psychological health. The company was never given any indication Lubitz was depressed, the official said, and if he went to a doctor on his own he would have been required to self-report if he had been deemed unfit to fly.

The company has already changed its rules following the crash to ensure that two crew members are in the cockpit at all times. Many other airlines have taken similar steps or been advised by authorities to do so.

More and more information is coming to light about the lives of the passengers and crew members on Flight 9525. They include Iranian sports journalists who had been working at covering a big Spanish soccer game between Barcelona and Real Madrid; a group of young students from a German town who were returning from a school trip; two successful German opera singers who had performed at a Barcelona theater; and an American mother and daughter from Virginia.

Most of the people on the flight were from Germany or Spain, officials have said. Searchers at the mountainside crash site are continuing with their precarious mission to recover the remains of the dead.
