You've bought what you need. The grocery cashier asks, "Will that be paper or plastic? You reply "Plastic, please." This seems like a simple question and there are plenty of reasons we choose plastic: easier to carry, lighter than paper bags, possibly less damaging to the environment, less expensive to the shop owners, able to be used as trash bag, and so on. There are different opinions on plastic and paper. Now let's follow the travels of 3 plastic bags. It begins at the grocery store with the customer's choice. Plastic Bag 1: As the waste engineer come by and pick up the trash, the first plastic bag falls out. It sits on a small street for a couple of hours until a car comes along and takes it down to the road. Then a gust of wind blows it across the road, then another car, then another gust of wind finally makes its way to the beach. Water fills the plastic bag and makes it look like a jellyfish. A seal  swims by, thinking it looks very interesting, and swallowed it. The plastic bag may stay in the seal's stomach for months, maybe years. You see, our lovely animals have been living thousands of years in a world where everything can be eaten. Plastic Bag 2: This bag does make its way to landfill . Before they have a chance to cover up the thousands of pounds of daily waste, a strong wind comes up and blows these plastic bags out of the landfill. Once the wind stops, workers will be sent to collect thousands of bags around. But they can't possibly get them all. So our little bag continues his adventure getting caught in trees, eaten by birds or making its way to our lakes or rivers. Plastic Bag 3: The last bag also blows away but is caught in a landfill where it sits for many years, as all the trash is wrapped in a big plastic bag, making natural degradation  impossible. Although workers do much work to make sure water and air system won't be polluted, some do. Guess what, plastic bags are made from petrol, a harmful waste material, which in one way or another makes its way to the environment. Another... According to the passage, what is NOT the reason for a customer to choose plastic bags? A) He can use plastic bags to carry trash later. B) He finds paper bags heavier than plastic bags. C) He finds plastic bags more convenient to carry. D) He can save money for plastic bags are cheaper.

A new semester has just started and a number of parents are registering to change their children's names, in the hope that it will change their temper or help their children drop bad habits, like addiction to the Internet.     One mother surnamed Shi renamed her son, a primary school student, Hengfu, which means eternal happiness in Chinese. She decided to change the boy's name because he always did poorly in study. She has had him tutored after school, but he always earns low marks in school. So Shi turned to a name-giving master. "I hope the special recipe could bring him good luck," the mother said. Teachers in the city say a few students in every school, most nearing graduation, change their names at the start of every new semester.     A naming agency said it has found names for nearly 1,000 students since setting up the shop in 1998. The store said its professionals analyzed the defects   of a person's original name, and suggested a new one based on the person's birthday and other fortune-telling skills.     Buying a new name costs between 800 yuan and 10,000 yuan. Parents also have to register the name at the local police department for a small fee. This will legally change their child's name on all documents, including ID cards and passports. Hu Jie, a university student who changed her name in her final year of high school, said the new name confused her. "I always had no idea who my classmates were calling when they used my new name," Hu said, adding that she wished she had kept her old name. But parents may be ignoring one thing: name changes might encourage kids to believe that fate is more important than their own efforts. From the passage, we learn that   _  . A) students are very satisfied with their names being changed B) name changes may have a bad effect on the development of children C) naming agencies change the names of children by scientific evidence D) to register the new name at the police department is usually free of charge
