I recently found the website speakspeak, which is a very good resource to help you practice your English. I found some very good activities here for Survival level students. The grammar is the Present Simple. There are three phases for the exercises.
- The Present Simple
- The Present Simple as Questions
- The Negative Present Simple
They are all gap-fill activities where you must type or choose the correct answer
THE PRESENT SIMPLE
THE PRESENT SIMPLE AS QUESTIONS
THE NEGTAIVE PRESENT SIMPLE
In all of these activities the website gives examples of the grammar you are using and it gives you the chance to check yur answers.
