Article: Mrs. Janes gave music lessons at a school.She had a good voice and enjoyed singing, except that some of her high tones sound like a gate that had forgotten to oil.Mrs. Janes knew her weakness well, and took every chance she could find to practise these high notes. As she lived in a small house, where she could not practise without disturbing the rest of the family, she usually went for long walks along the country roads whenever she had time and practised her high notes there.Whenever she heard a car or a person coming along the road, she stopped and waited until she could no longer be heard before she started practicing again, because she was a shy person. One afternoon, a fast, opened car came up behind her so silently and so fast that she didn't hear it until it was only a few yards from her.She was singing some of her highest and most difficult tones at that time and as the car passed, she saw an anxious expression came over the driver's face.He stopped his car suddenly, jumped out and began to examine all his tyres carefully. Mrs. Janes didn't dare to tell him what the noise he had heard really was, so he got back into the car and drove off.
Answer: She sang terribly, she was no singer at all.
answer:
How did Mrs. Janes sing?

Article: Recent research has claimed that an excess of positive ions in the air can have an ill effect on people's physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm, earthquakes when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing, or from TV sets, duplicators or computer display screens. When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue , excessive anger, and some particularly sensitive people feel sick or even suffer mental disturbance. Animals are also affected, particularly before earthquakes, snakes have been observed to come out, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California. Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with streams or waterfalls. To increase the supply of negative ions indoors, some scientists recommend the use of ionisers. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.
Answer: It's a charged particle.
answer:
What is an ion according to the passage?

Article: Some diaries from Jackie Chan's blog January 4, 2009 Lately I've been busy in Beijing having meetings to discuss my new movie. I also attended John Wu's ceremony of his new movie,Red Cliff,which took two years to complete. I'm good friends with the director John Wu and the main actor Tony Leung. January 5, 2009 Today I went to record a television program for Beijing TV calledVolunteers Across China. This TV program is a large-scale reality show that is based on the idea that "good people reap good rewards" and it hopes to encourage people to be more aware and help the "good people" who are in difficult situations. January 6, 2009 I'm very pleased to _ that my Jackie Chan automobile website is set up and officially operating! I hope that through this automotive website, I can get in touch with more people who want to buy cars. January 7, 2009 Today, I went to record a song calledZhongguo Nian. This song was written by Chang Shilei. I sing this song together with Tan Jing. Chang Shilei is a naturally talented musician. He also has an interesting habit. His piano is placed next to his bed. When he wakes up, he plays the piano until he's tired, and then he lies down on his bed to sleep. January 9, 2009 Today I met with the producer and director ofLongwei Xiaozi ,and I also brought along my friend's daughter for a screen test. Although my friend's daughter grew up in China, her English is very good and it just happened by chance that this movie needs a young actress for a part, so I took her along to audition .
