[EX Q]: Article: Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these signs of madness caused by digital culture? Not at all. In fact, phantom vibrations and ringing indicate a fundamental principle in psychology. Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Working through the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn't. Obviously you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection" But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with "it's ringing" (a "false alarm"). This second kind of mismatch is what's going on when you imagine a phantom phone vibration. What does that mean in terms of your phone? We can assume that people like to notice when their phone is ringing, and that most people hate missing a call. This means their perceptual systems have adjusted their bias to a level that makes misses unlikely. The unavoidable cost is a raised likelihood of false alarms of phantom phone vibrations. The trade-off between false alarms and misses also explains why we all have to put up with fire alarms going off when there isn't a fire. It isn't that the alarms are badly designed, but rather that they are very sensible to smoke and heat and biased to avoid missing a real fire at all costs. The outcome is a rise in the number of false alarms. These are inconvenient, but nowhere near as inconvenient as burning to death in your bed or office. The alarms are designed to err on the side of caution.

[EX Q]: Article: We are not rich by what we possess but rather by what we can do without. ----Immauel Kant Many times my friend June would say, "If I ever get rich, I'm getting a completely new wardrobe and moving into a bigger apartment." I thought of her words and her chances of being rich are about as good as mine. But, to everyone's surprise, a few years ago June did come to large inheritance . At first June said very little about the money. As the initial shock disappeared, she became excited, June is a great believer in making lists, so I was surprised to find her writing down all the ways she would spend her new wealth. As time went on, she started revising the list. What had been midway down the list was now at the top. At last, I said to her, "You know, it isn't necessary to spend all your inheritance at once. Take come time; think about it." "I know, I know," she answered with a little bit anger. Then one morning June called, "I've decided how I want to use my new inheritance. I want to see what you think," she said. This wasn't something I looked forward to, but we had been friends so long. As we sat, June spread a sheet of paper on the table. To my great surprise, she had written only two words: Charities, and Grandchildren-in that order. Though I had promised to keep quiet, I couldn't keep from asking how she came to this decision. "Well," she said, "I took your advice and thought about it." She added, "Helping others means a lot to me, so I'm hoping this gift will help people in need." I interrupted, "But what about this big apartment you most hope to have?" "At first it was hard, but it doesn't seem as important any more", she answered with a smile. Then June moved her hand, and I could see a few words written in tiny letters at the bottom of the page. After having a look at the small print, I burst into laughter. June had written: AND one new wardrobe.
Question: From the passage we can learn that the writer at first _ .

[EX Q]: Article: In 1896, Einstein went to Zurich to study physics. There he met a girl from Hungary. They studied in the same class and the same interest in physics brought them together and they became good friends. Before long they fell in love. In 1903 when Einstein was 24, he married Merits, who was 4 years older than he. After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Merits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible. She was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even did that in their letters when one of them was away from their home. In1914, Einstein moved to Berlin and _ there. At that time his theory proved to be correct and he had become famous all over the world. But it was not long before the First Would War broke out. Merits as well as her two sons, who were on holiday in Switzerland, couldn't come back to Berlin any more. The war not only stopped Einstein's work but also broke up the warm, happy family. In 1919, Einstein and Merits had to get divorced .
