Hi Wang- Please see the corrections. Wang Chinese (Taiwanese),English Learning:English THE pencil is a very important tool for CULTURAL Development . There are many kinds of PENCILS. We can use THEM to write down everything THAT we want to say or draw a picture. We use PENCILS when we need to record something on paper. Hope this helps. Watch your use of articles such as "the" and "a" and also pay attention to singular and plurals when writing. When you talk about "many kindS" then we need to use the plural pencilS. Also usually only use "what" when asking a questions. Everything THAT we want to say... is the correct form. :)
