We have found plastic in the ocean and in animals like birds, fish and whales. But for the first time, scientists have found plastic in human poop (大便) , USA Today reported. The findings came from a study led by scientists from Environment Agency Austria The volunteers wrote down what they ate for a week and then provided a stool sample (大便样本) for testing.
About 20 small plastic particles (IM) were found in every 10 grams (克) of stool. "The smallest plastic particles can enter the blood, the lymphatic system, and may even reach the liver (肝脏)," said Philipp Schwabl, who took part in the research. They're not sure how the plastic got in the volunteers' bodies, either. But most of the volunteers said they drank from plastic bottles and also ate seafood that could include plastic from ocean pollution.
In fact, plastic is everywhere around us. Every year, lots of plastic waste goes into the ocean. Most of the particles stay in the ocean. Others can spread into the soil, and air. Could plastic in the air fall onto food and get into the human body?
Some past studies may also give us a clue. And even some drinking water has been found to have tiny plastic particles in it.

Everyone has a beautiful memory about their school life. Among many things, relationships are the hardest to leave behind. Some schools try to stop students' puppy love(早恋)in different ways. Anything about "love" relationship is not allowed. For example, a middle school in Fu'an, Fujian Province stops boys and girls from sitting together for meals and keeps boys from looking at girls for a long time; a middle school in Luo-he, Henan Province sets rules that boys and girls should meet in bright places with at least 5 other classmates, and if they meet secretly. they will be asked to go home with parents for more than a week and even advised to leave school: a middle school in Jinan, Shandong Province stops everyone from sending food and gifts to or receiving them from the opposite sex(异性). It also stops students from helping the opposite sex with bags and coats and requires a"44 cm" distance between boys and girls.
Some students are not satisfied with such rules. "Why should we have strict places for different sexes to eat? It's not using bathrooms!" Some people who care about the intelligence development of the students say that they should be more creative with fewer rules. For this, I'd like to say that middle school students are going through puberty. It's normal for them to have some feelings for the opposite sex. Schools should provide correct guidance and education instead of giving simple and strict rules and asking the students to follow.
What do the people usually do on weekends? Some people like to1at home, but others like to go out for a walk or play football. Mr Smith 2hard in a factory during (在期间) the 3.
