1.  But, when those happened, I couldn't know a word.

2.  In fact I don't know many words in the English text.

3.  Knowing more English words is extremely important for us to master this language.

4.  First of all, at the end of this semester I need to know about 10000 words.

5.  What's more, if you only know the words, you can't apply English to daily life.

6.  Only knowing these words will lead to awkwardness of not knowing how to express in the future.

7.  We not only know new words, but also we know how to use them in correct positions.

8.  In reading, when a student come cross a unfamiliar word, he can rely on the context to know the word more specifically, like whether it's a good word or a bad one, and to which aspect can people apply this word.

9.  As we know, vocabulary always set a great obstacle to the students who learn English as a foreign language, because when you know few words, you can hardly know what an article say, what an English speaker talking about and so on.

10.  In my opinion, memorizing long lists of words is a quick way to make us know more new words, which reading lots of books cannot provide us.
