Listen, record and compare the English phrases like in the study section. Complete the phrases with spaces by writing the missing words.

To do the exercise, follow the next instructions:

• LISTEN: To listen to a phrase, place the cursor upon it and click on the left button of your mouse.
• RECORD: To record this phrase, place the cursor on it, and keep the left button of the mouse pressed. The icon meaning that the programme is recording will appear. By releasing the mouse, you will automatically hear what you have just recorded, and imediately afterwards, the speaker's voice.
• COMPARE: To compare, click on the phrase with the right button of the mouse. You will automatically hear your record, and right after that the speaker. When you record a word or a phrase, this one changes in bold letters so you will know that it has already been recorded. You will also have the possibility of hearing what you have recorded by clicking on it with the right button of the mouse.
• FILL IN INCOMPLETE PHRASES - When you finish writing, press ENTER. If you got the good answer, your writing will remain in red and you will hear the phrase. If not, you will see where is the error and you will have to correct it. If you have any doubt, ask for help with the button
