Poor sleep is associated with a range of cardiovascular problems, including high blood pressure, heart attack, and heart failure. Both men and women are at increased risk for these conditions. But we continue to learn that when it comes to health problems associated with sleep, the particular risks to men and women are not always the same. A new study suggests that for women who already have heart disease, poor sleep may be particularly dangerous to their heart health. Research indicates that poor-quality sleep--and waking too early in particular--is associated with increased inflammation among women with heart disease. There was no similar association found for men, suggesting that women with heart disease and sleep problems may be at particular risk for inflammation that can be damaging to the heart. Researchers at the University of California, San Francisco investigated the relationship between sleep quality and inflammation linked to coronary heart disease. They also sought information about how an association between sleep and inflammation might differ between men and women. Their investigation included 980 men and women at first, and 626 completed the 5-year study. All of those included were suffering for coronary heart disease. The average age of men in the study was 66. Women were slightly younger, with an average age of 64. Researchers measured sleep quality by asking participants to rate their sleep over the previous month. They also asked for reports of some of the most common sleep problems, including difficulty falling asleep, difficulty staying asleep, waking frequently throughout the night, and waking too early in the morning. After 5 years, researchers repeated tests for inflammation and once again sought reports on sleep quality and sleep problems. When they analyzed data for both men and women together, researchers found no links between inflammations and sleep quality. However, when they...

The following tips will help you to become a more confident speaker. Practice where you can and when you can. And practice is good -- whether you speak to someone who is a native English speaker or not. It's important to build up your confidence. If possible, use the simple sentence structure that you know is correct, so that you can concentrate on getting your message across. Try to experiment with the English you know. Apply words and phrases you know to new situations. Native English speakers are likely to correct you if you use the wrong word. They usually don't mind if you use wrong grammar. Try to respond to what people say to you. You can often get clues to what people think by looking at their body language. Respond to them in a natural way. Never translate everything into your own language. It takes you much time and you'll find it difficult to find an English answer right away. You don't know how to do well. The more you want to act well, the more slowly you act. This will make you _ If you forget a word, do what native English speakers do all the time, and say things that 'fill' the conversation. This is better than remaining completely silent. Try using 'um', 'er', if you forget the word. Don't speak too fast! It's important to use a natural rhythm in speaking English, but if you speak too fast it will be difficult for people to understand you. Try to relax when you speak, and you'll find that your mouth does most of the pronunciation work for you. Speak English at a normal speed. Final tips: Try to become less hesitant. Don't be shy to speak -- the more you do it, the more confident you'll become. Remember to be polite -- use "please" and "thank you" if you ask someone to do something for you.

Q: Read the following article and select the best answer. Article: It was 3:12 a.m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the crackling of flames somewhere below there was not a sound in the two-storey house at Baldwin, Long Island. With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke-filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn. The nine-year-old raced back into the house and upstairs to his mother's room. He found it impossible to wake her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and , as a fireman said later, "acted with all the self-control of a trained adult." On the bedroom telephone, luckily still working, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother. First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden. He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor? Grasping firmly a ball of string from the garage, Glenn raced back into the house and dashed upstairs to his mother's room. Tying one end of the string to her hand, he ran back, laying out the string as he went, through the hall and back out into the garden. Minutes later he was telling fire chief John Coughlan: "The string will lead you to my mother." Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor. Question: How did Glenn help the firemen to save his mother? - By throwing water all over her and her bed. - By carrying her to safety with his brother. - By pushing and pulling at her. - By tying a string to her hand.
A: By tying a string to her hand.
