—I've prepared everything well. Let's go now.

    Every school day, we use schoolbags to carry all of our things to school. But have you ever thought about the 1 of schoolbag?

    In the Han Dynasty, when old-style private (私人的) schools were 2, students used bamboo boxes to carry things to school. There were usually two or three layers (层) in the boxes. Kids put different school things, like blushes and 3 in the boxes. Hundreds of years later, people 4 a new kind of schoolbag called the budai. The budai was not so 5 as the bamboo box so that it was easy to carry. Later in China, military rucksacks (军用帆布包) became 6. Ask your grandparents or parents about these bags. Maybe they can tell you how they 7 used them when they were in school.

    A new style of schoolbags has appeared in recent years. Many of them have pictures of cartoons or pop stars on them. They are more 8 to use. Some students have special bags with 9. Students pull them just like pulling a luggage case (行李箱), so that it's easier for them to carry heavy textbooks.

    Schoolbags still 10. Can you imagine what future schoolbags will be like?

    Imagine a family is having dinner at a restaurant. What are they doing? Maybe they are eating and drinking. More possibly, they are looking at their own phones and ignoring (忽视) one another. These days, this is a very common scene and there is a word for it: phubbing.

    Phubbing is an ordinary part of modern life. When a conversation gets boring, we turn to our phones.

    Often, people are using their phones to chat with other people or look at past memories. It's funny. They could be chatting and making memories with the people next to them. But most of the time, they are losing themselves in an unreal world alone. That is not a good thing.

    A study says that phubbing may ruin our rela­tionships. When married people become phubbers, their relationship stops satisfying (使……满足) them and they may argue more. Phubbing hurts friendship, too. People say their phubbing friends don't really respect them.

    But why do people become phubbing? It's because there's a whole world inside our phones. That world's pull is very strong. It's almost like a drug. People can't control themselves, so it's hard to blame (责备) them for phubbing.

    If others ignore you, be patient with them. Remind them to put their phones down and talk to you. You should pay attention to your phubbing habits, too. If you spend more time on your phone, stop. Put your phone away, look at the people beside you, listen to them and have fun with them.

    Like most other fathers, my father cares a lot about his children. He cares about my (healthy) and how I am doing in school. He never misses any parents' meetings in my school. Yes, my father is ordinary father just like the others' fathers.

    But my father does a special thing he is not at work. He volunteers in a local hospital. He spends time (help) to take care of the sick people. He is happy (speak) with them, listen to them, and even read newspapers for them. Sometimes, he will take me with him, and when I'm there, I see that all the patients, (doctor) and nurses like my father very much. They always smile and say hi when they meet him, and some of the younger patients even run to him and ask a hug.

    Also, we (encourage) to take part in community service by my father. He believes that the happiest people are not those getting more, those giving more. And he always tells us, "To make (you) happier, you should help others." I am proud of my father.

—I think he's on the way back. About thirty minutes later, he will arrive.

—Yes, he does. He thinks sports can make him keep fit.

—All the work is simple. I can do it with­out difficulty.

—I finally passed the test although it's a hard work.
