Nobody likes doing the dishes, but it turns out that doing this daily task might pay off in an unexpected way. According to a new study published in the Journal of Pediatrics, washing dishes by hand instead of using a dishwasher might prevent the development of allergies.

    Researchers in Sweden surveyed the parents of 1,029 children ages 7 and 8. They discovered that children whose families hand-washed the dishes instead of using a machine were less likely to have allergies.

    Earlier research has shown that dishes washed by machine are cleaner than those washed by hand. So why would kids who eat off slightly dirtier plates be better off when we talk about preventing allergies? One explanation is based on a theory known as the "hygiene hypothesis (卫生假说)," which says the reason why kids develop allergies is that their surroundings are actually too clean.

    Your immune (免疫) system keeps you healthy by fighting germs (病菌) like bacteria and viruses. But when you have allergies, it overreacts and tries to fight ordinary things like pollen (花粉) or certain foods.

    Being exposed to germs, particularly early in life, is good training for the immune system, says the lead author of the study, Dr. Bill Hesselmar of Queen Silvia Hospital in Sweden. "You excite the immune system in various ways and it becomes tolerant."

    This study shows that while using the dishwasher might be easier, the old-fashioned method of cleaning up could be better for your health.

    In our country we think being modest(谦虚的) is a virtue(美德) and being proud is a bad thing. One day, I heard an American boy say to a Chinese student, “You speak very good English.” But the girl answered, “No, no. My English is very poor.” The foreigner was quite 1 at the answer. Thinking he had not made himself understood or the girl had not heard him 2. He said, “Yes, indeed, you speak very well.” 3 the girl still kept saying, “No.” In the end the American boy could not understand and didn't know 4 to say.

    What's wrong with the girl's answer? She didn't 5 a compliment(恭维) in the same way as the American people do. She should answer “Thank you” instead of “No”. She 6 understood what the American boy had said, but she thought she should be modest. In the 7, people will feel 8 and confident when they are praised. So if someone says the 9 you have cooked are very delicious, you should say, “Thank you”.

    If you are modest and say, “No, I'm 10 I can't do it well”, while working in a western country, people may think that you really can not do it. If you often say, “No”, you'll certainly be looked down upon by 11. When asking 12 a job, if one says something like, “Yes, I can certainly do it” instead of “Let me have a try”, he or she will 13 get it. So in the west, you should be brave to show your self-confidence. In my opinion, being confident does not 14 being proud, so sometimes you should be confident 15 being modest.
