阅读理解。

      Learners report two main difficulties in reading, which may be linked. There are too many unknown

words and as a result reading is simply not a pleasure. For some students, even reading in their own

language is a chore. 　　

     Having a wide vocabulary is essential to making sense of written language. Of course, this is a circular

argument, because the more you read the more vocabulary you learn and the more words you know the

more easily you can read. Don't make the mistake of reading with your dictionary beside you, looking up

every single new or doubtful word. This is laborious and prevents you from practicing the skill of prediction. 　　

     Sometimes in reading you find a word you know but the sense doesn't seem to fit in. This is not

surprising because words have so many meanings and degrees of meaning. What is more, part of their

meaning is shaped by the words around them. Keep looking at the surrounding words and asking yourself

"what sort of meaning would make sense here?" 　　

     The more that people study the reading process, the better they can pass on to language learners a range

of advice to choose from. People have learned to read in all kinds of ways. Here is some information that

could help you plan to be a better reader in the foreign language you are studying. 　　

     1) Work out the general meaning first 　　

     When people read in a new language they often feel they must take a detailed approach, focusing in every

word, particularly those they don't know. They read as if they were using a microscope, looking carefully

at each of the small pieces (the individual words), but not necessarily seeing the whole picture at first. This is

called the "bottom-up" approach. Other readers try to look first at the big picture(the "top-down" approach),

attending to individual bricks only as necessary, a process that involves some intelligent guesswork. Generally

this second approach is recommended by successful learners. 　　

     2) Interactive reading 　　

     Another way of thinking about reading is to describe it as an interactive process, where the text brings

something to you and you bring something to the text. Readers bring together all their knowledge of the

world with what they see on the page in front of them. That is why, when reading in our own language,

we don't need to read every word. We add meaning which is not actually stated. 　　

     3) From supported reading to independent reading 　　

     Language learners start by needing considerable support as they read. Textbooks supply this support

in the form of introductions that summaries the contents, glossaries, pictures, explanations of new

grammar points. In your reading you need to move gradually from this support to reading more the text itself.
