It is time to improve my vocabulary comprehension Last night I watched a video talks about the English learning. In this video, it says that input is very important. For English learning, you need to grasp enough vocabulary before you start to speak out a complete sentence. If you can pronounce the IPA sounds correctly and know grammar rules exactly, you still limit to express yourself effectively. So vocabulary is the bar of your English expressions. In this video, it says 30,000 vocabulary words is needed if you want to read novels and understand 98% of the related contents. Now I can understand my teachers even they speak fast, also they can understand me in lessons. So I think it is time to improve my vocabulary.
