The only way to improve Chinese reading skills is to read more, and read more level appropriate materials.
In this aspect, the world is friendlier to high level students. The materials they can read are everywhere, news papers, magazines, novels, essays.
However, wherever lower students look, they only see tons of Chinese characters they have not learned. For them, the best reading materials are their textbooks, especially the ones having a tight control of the vocabulary used, such as the Chinese Reading and Writing series. This series is for beginner students to learn very limited Chinese characters but to do lots of reading and writing exercises.
On top of reading more, read aloud also helps. Reading aloud has tons of benefits. That is when we have to use our voice to manifest what we have been doing in our head.
