Question: Article: The summer of 2012 was full of reports of extreme weather: one of the warmest years on record in the US, the wettest summer in the UK, and the worst drought in East Africa. In short, extreme weather seems to be becoming the new normal. Weather extremes are not that extreme any more. Heatwaves, droughts and wildfires are the new reality of a warming world. And this should not come as a surprise. Scientists have been warning for years that as the planet heats up, we will have to deal with more dreadful weather. Although not every extreme weather event is the result of climate change, scientists are now much more confident about connecting weather events with climate change. In 2011, the UK had a warm November. Researchers say that it was at least 60 times more likely to happen because of climate change than because of natural changes in the earth's weather systems. All the news shows that climate breakdown is occurring faster than most climate scientists had expected. But isn't it too expensive to stop the climate from changing? Well, yes it costs. So everything is just as usual. It would be wrong to believe that to let things continue as they always do is the cheap choice. Instead, it is very expensive. Just one example: droughts in the US, Russia and the Ukraine sent food prices to a record high. According to the World Bank, the price for corn increased by 113% in some markets in Mozambique and in Sudan. This is the kind of cost that often gets ignored. I believe intelligent climate action can help create new opportunities for jobs in Europe, for encouraging creativity and competitiveness, for spending less money on energy.

Options: (A) the UK had a warm November (B) the US had many wildfires (C) the UK had a dry summer (D) East Africa had little rain

Question: Article: Can you imagine exchanging the pleasure of city life for a quiet life in the countryside? Many people want to move from the country to the city because they think that life in the city is more exciting and better than that in countryside, especially young people who like new, modern things. People like popular things and feel that they can only find the latest styles in the city. However, it is possible to enjoy the higher quality of country life and still enjoy some of the advantages of living in the city. Nowadays, traveling is fast and easy, and information can be found on the Internet, so many people are able to do their work in home offices. Because they have e-mail and personal computers, they don't have to be in big cities to manage their businesses. It is not important where they actually work because the results of their work can be sent everywhere with e-mails. Therefore, there is no need to put up with all of the disadvantages of the city. Now they can escape busy city life to enjoy the quiet country life and still be able to have successful jobs. Other people are interested in technological things and high-tech jobs and think they can only find them in big cities. If they want to find a job, especially a good position in a company, they think that they have to live in a city. For these jobs, they are willing to put up with many of the disadvantages of city life, such as crime, heavy traffic, and pollution.

Question: Article: When children learn a language, they learn the grammar as well as words or vocabulary. No one teaches them; children just " _ ". Before babies begin to produce words, they produce sounds. Some of these sounds will remain if they occur in the language being learned, and others will disappear. This is called the "babbling stage". A child does not learn the language "all at once". The child first speaks only one-word "sentences". After a few months, the two-word stage arises. During this stage, the child puts two words together. These two-word sentences have definite patterns and express grammatical and meaningful relationships. Still later, in the telegraphic stage, the child will produce longer sentences. These longer sentences are mainly made up of content words. The child's early grammar lacks many of the rules of the adult grammar, but gradually it will become perfect. All normal children everywhere learn language. This ability is not dependent on race, social class, geography, or even intelligence . This ability is uniquely for human.
