求这篇文章的英文词解!全文：我读了《小学英语开心阅读训练五年级本,我认为它是一本非常好的课外阅读训练本.里面共有10单元

This summer break,I read the book "Elementary English Reading Exercise Gr Five" I think it is a very good extra-curricular reading exercise book.There are a total of 10 units in the book,and each unit talks about different stories and things.At the end of each unit,there are also unit quizzes,which include many different short excerpts,helping to improve our reading skills.If you can not understand the contents of the excerpts,you can check the translation section.When you finish the questions,you can check your answers in the analysis and answers section at the back of the book.The reasons for the right answers are also listed there.
This is a excellent extra-curricular book to practice reading English,I like this book a lot!
