Let me give you an example: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Article: In Germany, English expressions are used in conversations and increasingly in written form. Advertisements are often expressed completely in English. When I go to the gym, there are "aerobic-classes ". We "warm up". We go "jogging." In business, we attend a "meeting" and we have "good connections." Other nations, like France, have taken action to protect their language from the influence of "Americanization". In Germany, however, there is concern that those rules could be connected with Hitler's Third Reich , when the language had to be pure. If the government curbed the use of English words now, this could be considered by some as a return to that terrible past. Some German citizens are now trying to stop the use of English vocabulary in German. However, I think generally it is not a big deal to use some common English expressions as they often describe things more directly. But we should know that it is important to use English correctly. All too often, bad English is spoken or even written instead of good German. The proper use of the German language would be the better choice. However, there are some fields that require the use of English words, for example, in the high-tech communication and the Internet fields, there is no alternative to English. Also, I think sometimes I have to speak English when I introduce some scenic places to tourists. I think you have to find a balance and decide when it is better to use good German in place of bad English or when the use of correct English words is more suitable. Languages have always changed naturally, and I disagree with a restriction by law. Some nice expressions borrowed from other languages can make a conversation more vivid.

From the passage, we can learn that when Hitler was in power, _ in Germany.
