    Many textbooks are not written in the kind of English that we speak every day. In fact,

sometimes the reading is so difficult that it almost seems like a foreign language. In a

way, it is the language of science. You should not expect to be able to read a difficult

science passage the same way you read an interesting story; you should not expect to read

it easily and all at once. Instead, you may have to read it several times through, catching

on the meaning of difficult words, going back over difficult sentences, and finally putting

the whole thing together. Do not be discourages if the whole passage don't make sense to

you at first. You need to pick it apart patiently until you can understand it.

    These are the steps to follow when you are reading something difficult: 

    ☆1. Start to read normally until you run into a sentence that doesn't make sense to 

         you. 

    ☆2. When a sentence doesn't make sense, go back and read it again more slowly. 

    ☆3. Look for any word you don't know in the sentence. Try to understand their meanings

         using word parts and context clues(上下文线索). If necessary, look them up in the

         dictionary. 

    ☆4. Look at the next few sentences to see if they explain more about the sentence you

         are working on. Do not read very much farther ahead until you understand what is

         being said. 

    ☆5. Finally, read the sentence again. Try to put it into simpler words. 

    ☆6. Read through the passage once. Try to understand all the hard parts well. Then

           read the whole passage once more at a usual speed. This helps you to put all

           ides together. The stops sound a lot harder than they are. It is really just the

           normal way good readers understand anything that is difficult to read. After you

           have done the best you can this way, you should always feel free to ask for help

           from your teacher, if you have one.
