foreign language. With a limited vocabulary anyone will also has a limited understanding in terms of reading, writing, speaking and listening. By having and mastering the vocabulary,
student’s ability in reading increase too. As beginning readers, children use the words they have heard to make sense of the words they see in print. Reading involves much more than
word recognition, the ability to recognize the sound and meaning of the printed symbol is basic to the reading process.
Vocabulary and reading can’t be separated, because both of them relate to each other. As the writer explain before, by having and mastering vocabulary we will know the
meaning of vocabulary in the context. It can also help to avoid making mistake in understanding. Vocabulary is very important to reading comprehension. Readers can’t
understand what they are reading without knowing what most of the words mean. As children learn to read more advanced texts, they must learn the meaning of new words that
are not part of their oral vocabulary. One reason why children find reading in some subject fields difficult because of
their lack of vocabulary. Where as in fact of vocabulary is the most important thing in reading skill. Most of us if we find the difficult word, we still just continue our reading in the
hope that the word we read is not really important or that it’s meaning will become clear later on. But sometimes these word that we passed usually as the key of our reading and
understanding. We can not catch and grasp the idea from our reading as well as possible. So looking up the difficult words in dictionary is better for us.
