【1】 在我的家乡in my hometown；发生 take place；很大的变化great changes ;change既是名词，也可作动词；根据语境可知，本句强调过去的动作对现在造成的影响和结果，故使用现在完成时态：has/have+动词的过去分词。 所以答案为： Great changes have taken place in my hometown/My hometown has changed a lot./There has been great changes in my hometown.

【2】The books这些书；too...to...太...而不能...; for sb.对某人来说； buy动词，买；afford动词，承担得起; so...that...如此...以至于..., 引导结果状语从句。所以答案为： The books are too expensive for me to buy/afford/The book are so expensive that I can’t buy/afford them.

【3】固定句型：It’s +形容词+of +sb. + to do sth. 意为“做某事某人是怎样的”； careless形容词，粗心的； forget to do one’s homework.忘记做作业。 所以答案为：It was careless of Tom to forget to do his homework.

【4】the new library in your school 你们学校的新图书馆；build动词，建造，built是其过去式或过去分词；去年last year；根据语义可知，本句为过去时态的被动句,其结构：was/were+动词的过去分词。 所以答案为：Was the new library in your school built last year?

【5】固定句型：It’s +形容词+for +sb. to do sth., 意为“做某事对某人来说是怎么样的”。necessary形容词，有必要的； receive training 接受训练；do the task做任务； before介词，在...之前。所以答案为：It’s necessary for them to receive training before doing the task.
