I need to strengthen the skill of describing things. my ability to describe things.

Though I have been learning English for several years, I still do not how to describe things in English with (using the) proper words. This makes me feel frustrated (frustrates me). Today I was asked what exactly is steamed bread is? Geeze, I do know what exactly what it is, but I am not able to explain it in English. I need to strengthen the skill of describing things. my ability to describe things.

别担心。我也不会用中文描述任何东西。再说，我连电视听不懂因为太快。
