He aced the test

In English, you can economise the use of words. For example, instead of saying 'He got an 'A' in the test.', you can simply reword it as 'He aced the test.'

If you are ready to listen to someone, you need not say 'I am ready to listen to what you have to say.' Rather, just say "I am all ears."

If you laugh until you bend your body forward when you watch something really comic or funny done by someone, you need not say 'His comic act really made me laugh until I bent my body forward.' Just say 'His comic act had me in stitches.'
