Wo yao shuo zhongwen. Shen(Xian)zai wo ke yi shuo yi dian dian de zhongwen. Wo bukeyi xie hanyu.

Wo shi meiguaren（mei guo ren）. Wo shuo de yingwen.

Da bufen de shihou wo you(yao) gongzuo. Ka(Ke) shi wo xihuan chi fan de bieda(?) guo he luixing（what dose it mean?).

let me help you translate it into chinese:我要说中文。现在我可以说一点点的中文。我不可以四写汉语。

我是美国人。我说英文。

大部分的时候我要工作。可是我喜欢？？？（sorry，I can't understand ‘chi fan de bieda guo he luixing’）

and between the two words,you'd better put a space.For example:keyi=ke yi.

加油！

First notebook entry: Introducing myself

Wo yao shuo zhongwen. Shen（xian) zai wo keyi shuo yi dian dian de zhongwen. Wo bukeyi xie hanyu(or hanzi will be better:)）.

Wo shi meiguaren(meiguoren). Wo shuo de yingwen.

Da bufen de shihou wo you gongzuo. Kashi wo xihuan chi fan de bieda guo he luixing.(okay, I know what you are trying to say. So, it will be: wo kaishi xihuan chi biede guojia de shiwu he lvxing.)

我要说中文。 现在我可以说一点点的中文，我不可以写汉字。

我是美国人。我说英语。

大部分的时间，我有工作。 我开始喜欢吃别的国家的食物和旅行。

I hope it will help you. :) you did a very good job. Your pinyin is pretty good. You can have a try to start type Chinese.
