нужно реально надеюсь на вашу

if she passed the exam , her parents will buy her a new laptop

if my computer didn't crash , i wouldn't loss all my work

if you had a MP3 player , you could listen to music

if you told me your email address , i could send you the pictures

if you installed antivirus software , you wouldn't get virus

if you promised me to take care of my smart phone , i will lend you.

if you join a social network, you will be able to keep in touch with all your friends
