The topic this week in the IELTS preparation class is ENVIRONMENT. You can find many English exercises about the environment at The Web Language Lab. They also have exercises about other topics that we'll be studying about in the IELTS preparation course.
Take some time over the holiday and see how many of the exercises you can complete. When we return after the break we will continue with the topic GM foods (genetically modified). There's an exercise about that topic too: The Web Language Lab
Enjoy your holiday!
