When I first learned to write in English，I ran into much difficulties. The main problem was in that I always thought in Chinese and tried to translate anything into English. My teacher advised me to keep my diary. I followed her advice and should put down 100 words or so each day. Soon I began to enjoy talk to myself on paper as I was learning to express me in simple English. One day I wrote a little story and showed to my teacher. She liked it very much and reads it to the class. All said the story was a good one. Their word were a great encouragement to me.much改为many

(答案→)much改为many 解析：短文改错要注意句子中人称和数是否一致，时态是否一致。各种词性之间的区别以及一些常用句型，固定短语的应用。要从细节着手，在平时要多积累。【小题1】much改为many 后面的名词difficulties使用的是复数形式，故使用many修饰，much不能修饰可数名词复数形式。【小题2】in改为that 本句中的that引导的是一个表语从句，that在句中不充当任何成分。In是多余的。【小题3】anything改为everything 代词anything通常用于疑问句和否定句中。而本句是一个肯定句，使用everything。【小题4】my改为a 固定搭配keep a diary写日记。不需要使用My来修饰名词。【小题5】去掉should 本句中的put down与前面的keep是并列关系，不需要使用should。【小题6】talk改为talking 固定搭配enjoy doing sth喜欢做某事。Enjoy后面接动名词doing的形式。【小题7】me改为myself 表达自己的意思使用express oneself。使用反身代词作为express的宾语。【小题8】show后面接it 固定搭配show sth to sb=show sb sth向某人展示某物。It指代a little。【小题9】reads改为read 动词read是一个不规则动词，过去式和过去分词都使用read。【小题10】word改为words 本句中的words指他所说的话，与后面的were保持一致都使用复数形式。

哦，回答的不错

这个解释是对的

C解析蛇不是一个种群；灭鼠时，如果只采取杀死老鼠这一办法，效果往往不好。如果我们杀死了一半老鼠，存活的老鼠数值降到1/2K值，老鼠的增长速率达到最大，很快就恢复到原来数量，在灭鼠的同时也要降低环境的K值； “S”型增长曲线中，种群增长速度先增加，在K/2水平上种群增长速率最大，然后再逐渐降低；由于种种因素的干扰，人类自身的出生率，其大小并非由人类自身的生育能力所决定，关键要看该国家或地区的人口政策及人们的生育观念。
