Once the trap door closes on the victim, the enzymes(酶）similar to those in the human stomach slowly digest the insert. When dinner is over, the plant opens the trap door and is ready to trap again.
Meat-eating plants grow mostly in wet areas with soil that doesn"t offer much food nutrition. In such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years. North America has more such plants than any other continents.
Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers full of nectar(花蜜).
Hair-like growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes can get to work. A tiny insect can be digested in a few hours, but a fly takes a couple of days.
Some of these pitchers are large enough to hold 7.5 liters. Meat-eating plants only eat people in science fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn"t a good place to get a drink.

举一反三
You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on tbe other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. Are you still in a wonderful mood? Impossible!
Communieating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.
Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others" pity or respect.
When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted. When the knife of a negative person is put in you, you have the heavy feeling that, all in all, brings you down.
Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but this is to lower you to that same negative level and they won"t feel ashamed of themselves about that.
Negativity often affects happiness without even being realized. The negative words of others at the start of the day can be attached to you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.

Do you have a sore throat, a running nose and a headache? Do you keep coughing and sneezing? If you do, the chances are that you have a cold or perhaps flu---but which one? Although both colds and flu are caused by viruses, they are very different illnesses.
Colds, which usually last about a week, affect the nose most. They commonly cause a running nose and sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.
Flu is a much more serious illness and is caused by different groups of viruses. People with flu usually get all the symptoms(症状) described above. However, they also get a high fever, a dry cough and much worse aching. Fever is one of the characteristic symptoms of the flu for all ages. The symptoms also last much longer. Sometimes they don’t disappear for at least two weeks.
Flu can be a deadly disease. The elderly(年长的), who are weaker and less healthy than most younger people, can die from flu. This is one reason why old people are advised to have a flu injection(预防针) before the start of winter when flu is most common. This injection is inexpensive and definitely（明显地）worth it.
If you have a cold or flu, you must always deal with used tissues(手巾纸) carefully. Don’t leave dirty tissues on your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze! You don’t want to see the small drops of liquids blown(喷) out of your nose and mouth when you sneeze, do you? Disgusting(令人作呕), eh? Now you can understand why it’s a good idea to cover your nose and mouth when you sneeze!
