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(锤子) or any sharp（锋利的） 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 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.

    Reading is a very important skill. 阅读也是一种提高你的英语的好方法。However, to make sure what you read isn't too difficult, it's important to know what makes texts difficult and how you can improve your understanding of them. Here are some suggestions.

    ①Understand the purpose of your reading. The way you read depends on the purpose of your reading. The kind of reading you do in class or for your homework is different from how you read a novel for pleasure in the summer holidays.

    ② Find background information. Find something out about the topic you are going to read.

    The more background information you have, the easier it'll be to understand the text.

    ③Increase your vocabulary（词汇）. The more vocabulary you have, the easier your reading will be.

    ④ Use your dictionary correctly. A common mistake is to read everything very slowly and carefully, looking up each unknown word. Sometimes this is necessary, for example, when reading exam questions. However, it takes a long time and can be very boring; it can even make understanding more difficult!

    If you've followed the above advice and still can't understand a text, then it's simply too hard for you. Stop reading and ask someone to help you. 没有人想要放弃。However, you'll just be wasting your time if you continue to work at a text that's beyond you.
