If you have a brother or a sister, you already know you are different from each other. You live together in the same house and have the same parents. {#blank#}1{#/blank#}． Why is this? One possible reason is the way your parents treat you.

    First—born children receive all the attention from their parents. Most families have much more photos of a first—born than any other child. Parents give them more responsibility（责任）.{#blank#}2{#/blank#}． As a result, first—borns are often responsible, hard—working and serious. They often want to do well at school and work.{#blank#}3{#/blank#}． For example, Gorge Bush, George Washington, and Lyndon Baines Johnson are all first—born.

    When a second child arrives, parents are more relaxed. The second child is allowed to be more independent. But he also has to compete with the first—born for the parents' attention and love. These children often choose different sports and hobbies to show independence.{#blank#}4{#/blank#}． They are often adventurous（爱冒险的）, fun—loving, and outgoing, but can be jealous（好嫉妒的）and get angry easily.

    The youngest child is the happiest. He has fewer responsibilities and more freedom. These children do not feel pressure to do well at school and work, but have to be creative to get their family's attention.{#blank#}5{#/blank#}．So, many famous talk—show hosts and comedians were born last.

    What do you do when you come across a problem while doing your homework? Andy would take out his smart phone, open a special app and searched the problem. Answers soon appeared on the screen.

    Nowadays, many students do homework with the help of the Internet like Andy. They search for information online, use apps or discuss through social networks like QQ and WeChat.

    “It's convenient.” Andy said. “You also learn by seeing how others work them out.”

    “It also improves students' abilities.” said John, another student. He said it's true for new types of homework.

    John's Chinese teacher often asks students to give speeches on great authors. When it comes to John's turn, he usually searches online, picks out certain stories and makes PowerPoint presentations.

    “I've become skilled at finding information online and using Microsoft Office,” Wang said.

    However, many students think this trend (趋势) also brings up problems. Some students just copy the answers online without thinking. They become lazy.

    A head teacher in Andy and John's school said that knowing how to use the Internet is important. The key is to have good self-control.

    “No matter how difficult the problem is, think about it independently (独立地) first,” the teacher said. “Be sure to understand the reasons behind the answers, or you won't make progress. If you don't have confidence about your self-control, ask your parents for help.”

    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 {#blank#}1{#/blank#} The volunteers wrote down what they ate for a week and then provided a stool sample (大便样本) for testing.
