Everyone who has eaten instant noodles knows that it's very easy to cook them quickly. However, have you ever heard of the danger of eating them?

    When taking out the noodles from the packaging, you will notice that they are joined together nicely as a piece. Do you know that it needs some form of wax coating (蜡涂层) to make them joined together nicely? Many people don't really care much about it because this seems very normal. However, studies have shown that the wax coating is bad for our body.

    It is advisable to have a break of 2-3 days before we start to eat another packet of instant noodles because our body needs about 3 days to clear that wax coating away. Do you know the danger of having too much wax coating in our stomach? It will lead to cancer if it is in our body for so long.

    Luckily, there is a way of reducing the danger before we eat instant noodles. First, wash the noodles with warm water, stir (搅拌) them and pour away the water containing the wax coating. Then repeat the first step and try to stir them again to wash away the wax coating on the noodles before cooking them. The shop vendors (供应商) will often wash away the dangerous wax coating.

    It is very easy to cook instant noodles but we must pay attention to the wax coating if we eat too much. Imagine having too much of it in your stomach. Oh, my! Hope this article will help more people know about the hidden danger!

    Life in the summertime is often full of pests. Like most Long Island homeowners, I want to ensure my suburban life with pest-free living. So it was with wide-eyed wonder that I greeted the smiling exterminator (灭虫者) who rang my bell.

    “We'll be serving your neighbors, Mike and Sarah (I'm not familiar with either one by name),” he waved in the other direction. “Since we'll have a team here tomorrow, we're offering a discount.” He came out with numbers beginning from $299 then in seconds to $89.

    “You've probably been seeing the ant hills around.” he moved toward my front walkway and lawn. “And have you seen the bees that dig nests in the ground?” he continued with his head shaking up and down pushing me to do the same.

    “What we do is spray three feet out from your foundation and three feet up.” As he was talking, and without breaking eye contact, he opened his iPad cover and began operating at the screen to show me frightening images. “It also kills other pests, like spiders. It is the best pesticide (杀虫剂),” he said, pausing for effect.

    He then went into soft talk to close the deal, correctly foreseeing that I would be concerned about safety and the environmental impact on my vegetable garden, plants and our little patch of planet here on Long Island. “The products are environmentally responsible, safe with children and pets,” he said.

    I'm unkind when it comes to unwanted visitors entering on my out-of-doors moments. Any insect found in my house or on my deck is bound to be poisoned or pancaked.

    Unfortunately for the exterminator, just as I was considering making an appointment, Billy, my fearless husband, pulled into our driveway, which made me ask for a business card out of politeness instead.

    When your pen is broken, the batteries (电池) in your toys run out, or you have some leftover food, what will you do with these things? You will probably throw them all into one bin. But actually, all of these pieces of rubbish need to be sorted (分类) separately.

    Rubbish sorting is a big problem worldwide. In recent years, some Chinese cities have been working hard on it. Shanghai has worked with Alipay to create a "green account (账户)" service. Account owners get points by correctly sorting their rubbish. Through the Alipay app, they can exchange the points for milk, phone cards or other products. The city is asking all people living there to sort their rubbish into four groups: wet, recyclable, harmful and dry.

    Wet waste is something you don't want but that pigs can eat. Plastics, glass, paper and other things that can be reused are recyclable waste. Harmful waste includes things like medicine, batteries and bulbs. Finally, any waste that's not wet, recyclable or harmful will go in the "dry waste" bin.

    Many other Chinese cities are also sorting their rubbish in this way. For example, Shenzhen has been doing this since 2012. Students there also receive waste-sorting guidebooks that they must study.

    In fact, there are still many workers specially working for sorting rubbish by hand in China. There is still a long way to go. But it's never too late for every Chinese to learn how to sort rubbish properly and protect the environment.

    If you don't sort your rubbish, all of it will go to a landfill (垃圾填埋场) and be buried together.

    These landfills can take up much ground that could be used for planting. The electronic waste you throw away, such as batteries or used mobile phones, can cause pollution. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.

Bright and early on the morning of our first full day in Antarctica, L' Austral's Captain Fabien's voice woke us up as it came through a loudspeaker. If we looked outside right now, he said, we'd see a beautiful sea of icebergs in the golden sunlight. My sister and I jumped out of bed, staring in amazement as we sailed past giant pieces of ice. In the distance, we spotted a group of humpback whales feeding on smaller fishes. Next door, my parents were also waking up to the sights of a new day in Antarctica. Over breakfast, my sister and I excitedly told them about the whales we saw from our room that morning.

You might not immediately think of "family vacation" when talking about a trip to Antarctica, but tour companies like Adventures by Disney are changing that. The company offers guided group trips to destinations across all seven continents in the world.

Our adventure started when we flew to Buenos Aires and explored the beautiful Argentine capital for a day. After leaving Buenos Aires, we flew to Ushuaia on an Adventures by Disney plane. Then, it was the journey toward the Drake Passage. After a speedy Drake Passage crossing, we reached Antarctica early, adding a half day to our scheduled four days on and around the continent.

To those unfamiliar with Adventures by Disney, the fact that you can experience Antarctica-the most distant, extreme continent-with Disney might be surprising. During the trip, there were thoughtful acts, from stamped postcards to send from an Antarctica post office to a champagne (香槟) party on our final stop of the journey; Adventures by Disney truly thought of everything for us. Antarctica is a life-changing destination packed with experiences that can't be copied. We experienced seasickness when travelling across the Drake Passage, hiked up ice hills alongside lovely animals, and had a taste of champagne. And honestly, it's going to be hard for the next family trip we may take to compete.

Why should mankind explore space? Why should money, time and efforts be spent exploring and 1 for something with so few apparent benefits? Why should many resources be spent on space 2 than on conditions and people on Earth?

These are questions that, understandably, are very often asked. Perhaps the best answer 3 in our genetic makeup（基因构成）as human beings. What4 our ancestors to move from the trees into the plains. and on into all 5 areas and environments? The wider the 6 spread of a species, the better its chance of 7 . Perhaps the best reason for exploring space is this genetic tendency to expand 8 possible.

Nearly every successful civilization has 9 , because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be 10 destroyed by the danger. With knowledge, we can 11 its effects.

Exploration also allows minerals and other potential（潜在的）resources 12 . Even if we have no 13 need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques 14 through exploration. The techniques may have medical applications which can 15 the length or quality of our lives.
