【文章內(nèi)容簡介】 re is plenty of water around. Once it finds a host, the young dodder plant will attach itself to it and start growing faster. At that point the dodder plant will drop its root. Dodder is thus a difficult weed to manage and a real headache for farmers. When it does get out of hand, dodder can greatly reduce a farmer39。s harvest or even destroy crops pletely. Before sowing their produce, especially farmers in warm parts of the world often check to make sure no unwanted dodder seeds have mixed with their crop seeds. This is a good way to stop dodder plants from making their way to a crop field secretly.（1）Why does the author mention spaghetti in the first paragraph?

In fact, showering too often can actually hurt your body in the long run. As Time39。s public health column explains, daily showers are mon due to social norms more than any proper health need. We connect being freshly showered with being attractive and pleasing, so we tend to showering often to feel better. But what39。s the ideal shower frequency? In terms of your health — not how you look or smell — probably once or twice a week, assistant professor of dermatology at George Washington University, Dr. C. Brandon Mitchell says. “Your body is naturally a welloiled machine,” he says. “A daily shower isn39。t necessary.” Of course, your situation may vary. If you have a job like car maintenance or construction, you39。ll obviously have a visible layer of dirt you39。ll need to wash off every single day. Similarly, if you work out every day, you may not have any health risks by washing every day, but you39。ll still be smelly. If you feel like you need to take daily showers for aesthetic（審美的）reasons, at least make most of them light showers. “I tell patients who shower daily not to soap their whole bodies,” Mitchell says. Hit your pits, butt and groin, which are the areas that produce strong smells. The rest of your body doesn39。t need much soaping, he says. Too much time spent under the hot water can dry out your skin, cause cracks（裂紋）that can lead to infections or germs getting into your skin, and take away the natural oils on your skin that help keep it healthy. So, even if you39。re aiming to be your most presentable, be sure to keep it moderate to avoid hurting your skin in the long run.（1）According to the passage, why do most people shower daily?
