Following a quick introduction on how to use these linking words, students can read example sentences where the words have been used in context. Following that, students need to fill the gaps with the correct linking word, and finally identify which sentences have or haven't used the correct linking word. There is a teacher's guide with the answer key on the second page. This worksheet has been carefully graded for second language learners and has been created by a trained, experienced language teacher, http://www.celiajenkins.com/teaching.
