R Corral: Great Inventions. Level 6. A2+

Ladybird Readers is an ELT graded reader series for children aged 3-11 learning English as a foreign or second language. The series includes traditional tales, popular characters, modern stories, and non-fiction.
Beautifully illustrated and carefully written by language learning experts, the series combines the best of Ladybird content with the structured language progression that will help children develop their reading, writing, speaking, listening and critical thinking skills.
The eight levels follow the Common European Framework of Reference for language learning (CEFR) and include language activities that provide preparation for the Cambridge English Pre-A1 to A2 (YLE) tests.
Great Inventions, a Level 6 Reader, is A2+ in the CEFR framework and includes practice for the Cambridge English A2 Flyers tests and KET exams. The longer text is made up of sentences with up to four clauses, more complex past and future tense structures, passives and time clauses.
