This past Columbus Day, my husband and I went fishing with some friends on their boat while our10 and 8-year-old kids were in school. We left the house all at the same time, about 7 a. m. My children walked to and from school every day and we knew they would be OK for a couple hours by themselves anyway. We told them to go home after school and we would be home around 4 p. m.We live on the Gulf Coast, and since it was a beautiful day, all of the adults decided to go fishing off-shore. At around 2 p. m. after a good harvest from the sea, we started back to the shore and unfortunately after some time, we ran out of gas. We were out of cellphone service, and what was even worse was that 911 wasn’t working. We didn’t have a radio either. Therefore, we were stuck waiting for someone to pass by. We were out there until 10 p. m. All the while my children were at home, expecting us to return shortly after they got home. At about 7 p. m. , when it was getting dark, my 10-year-old daughter thought something might be wrong so she walked to each house on the street until someone answered the door and asked the person what they should do. This was how we were finally found by the game warden (管理员) on the coast and “rescued”.Talking with that neighbor the next day, I was never so proud of my children. This neighbour explained to me, “What calmn ess both of your children showed when explaining the situation and how impressed I was with your children seeking help, even though they didn’t know me.” I never doubted him for a minute, though next time we go fishing we’ll monitor the gas more carefully.1.What did the author probably feel at the very start of returning to the shore?A Anxious.

Lost at SeaBPainkillers (止痛药) are turning out to be a real pain: according to a new study in the British Medical Journal. Taking them for just a week can increase your risk of heart attack by 50%. The research suggested that the risk related to the use of certain drugs was greatest with higher doses (服用量) and during the first month of use. The potential risk may increase by 75% for medicines like ibuprofen (布洛芬) and naproxen, and more than 100% for rofecoxib.It all sounds bad but, your risk is very low, — say, one in a million — a 100% increase meansyou still only have a two in a million chance. Of course, all painkilling medication that works can have side effects — nothing is safe and effective. Paracetamol (扑热息痛) has very few unless taken too much, in which case it can cause serious liver danger, but it isn’t very effective. Drugs lik e opiates are strong painkillers but easy to be addicted and often have other bad effects. Maybe you find that you are in a dilemma now. But don’t despair; you can refer to a pain clinic for some professional guidance. For ongoing pain, music and exercise may be the best choices to help you reduce the feeling of it.Scientists at Harvard have recently done a quite horrible study on mice. They made the mice experience extremes of hot and cold, applied pressure to their back legs and injected the capsaicin (辣椒素) into their feet. And then they timed how long it took them to respond to the pain. Lack of sleep increased the discomfort, while stimulants (兴奋剂) such as caffeine made them less responsive to pain. This has been widely reported that a good night’s sleep and a cup of coffee in the morning may help reduce pain.But anyway don’t throw the pills away because the study also shows taking small doses of drugs, such as for short periods of time can be effective and safe as long as your heart is in good condition.5.Which of the following painkillers has fewest side-effects?A.
