配对阅读：上栏描述了五位同学喜欢看的杂志，下栏是七份杂志的简介，请为上栏的每位同学选择一份合适的杂志。

    Zhang Zhouchen, a sixth grader, has published two novels in English.“Most people often read to learn English, but my secret is to write ”he said. "Reading is a way of taking in. But only when you use it for writing can you master it completely. “

    Zhang began writing his first novel at the end of 2014. He didn't mean to publish it at first. But a special experience made him change his mind the next year. He was chosen by his school to be a volunteer for a Hope Primary School. Every volunteer was asked to bring a gift for children and Zhang brought a football. "But I was surprised to find that there was no football field at this school, "he said. “So I had a wish to help them build a football field.

    How to achieve that? The novel came into Zhang's mind suddenly. By organizing the book sale, he got 100,000 yuan. He then spent it building a football field. Then he got about 130, 000 yuan by selling his second novel. He used the money to build a football field in another school.

    “I can never forget the smiles on the faces of the children who were having fun playing football, said Zhang. "It encourages me to help more poor children enjoy the joy of football.

    Read the passage carefully and complete the table with only one word for each blank.

    Back in the twentieth century, robots seemed to have a big future, at least in the movies. Like the robots servants in the Star War movies. It looked as if one day robots would do all the boring or dangerous jobs while the humans sat around doing something more interesting. But people were also frightened that robots might become the bosses, not the servants.

    Has it happened? You're still unlikely to see a robot walking around your town but that doesn't mean they don't exist. Robots are used in car making, and in areas which are dangerous for humans, in bomb producing and deep-sea discovering, for example. We employ robots instead of doing the job ourselves. According to the report, there are 750,000 working robots in the world today.

    These working robots definitely look like machines but many scientists are now trying to make robots look more similar to humans. So what will robots be able to do by the year 2030? There are already plans to use robots in hospitals and old people's homes. Robot nurses will remind patients to take their medicine or tell a doctor if the patient needs attention. But many people are worried about the idea of robots looking after the old, the sick and the very young, separating them from important human contact. It may also create unemployment. It is really possible that robots will be used for many jobs in areas.

    But can we be sure that the next generation robots will always follow human orders? Or even destroy them? Or will we be able to create robots with emotions? Only the future will tell.

    Do you go to school by bus? It is very important for you to know how to be safe when taking a bus, no matter whether you like it or not.

    First, don't run to the bus stop, but walk. While you are at the bus stop, you should wait in a safe place. Do not run or play while waiting. And never get into a car with a stranger.

    Second, don't talk in a loud voice when you are on the bus, so the driver will not be disturbed(打扰). If you need to talk with the bus driver, you'd better wait until the bus stop. Never throw things on the bus or out of the windows. Never play near the emergency exit(紧急出口). When there is a fire, the most important thing is to break the window with a hammer or any sharp things and then jump out.

    Third, when you are getting off the bus, make sure you walk (not run) three more steps away from the door. This is the best place to be around a bus. Stay away from the bus wheels and watch out for moving cars!

    Last, if you leave something on the bus, never return(回到) to the bus to get it. The driver may not see you come back and he may begin moving the bus. Also, if you drop something near the bus, tell the driver before you try to pick it up, so he will know where you are.

    When it comes to the letter grade on your test or homework, you might notice that there is no letter E. Have you ever thought about why that is so?

    In the A, B, C, D and F grading system, the first four letters are typically considered passing grades. An F in this system simply stands for "fail". The word "fail" happens to start with the letter F, which seems to leave out the letter E.

    The first college in the US to use a letter grading system like the ones we use today is Mount Holyoke College. In 1897, they began to use the following grading scale;

    A: 95-100% (excellent)         B: 85-94% (good)      C: 76-84% (fair)

    D: 75%( nearly passed)         E: below 75% (failed)

    We can see the inclusion of E instead of F.

    Gradually, the letter grading system became more popular all over the US. However, many schools decided to drop the E grade and go straight to F. There is no evidence(证据) to really support this, but one possible explanation is that teachers were worried that some students and parents might mistake E for "excellent".

    Why do we have letter grades? Well, part of the reason is that they made grading simpler during a time of great change for schools. As the 20th century began, growing cities and an increase in immigration led to larger school classrooms. Most teachers at that time thought this new letter grading system was an easy, fair and clear way to grade students.

    Today, more and more people think that letter grades don't fully show students' learning. However, as teachers try to improve grading methods, many parents continue to prefer the letter grades they got as kids, as they are familiar and easy for parents to understand. So while they might not be perfect, the letter grades probably aren't going away any time soon.
