Undergraduate / Common App - The catastrophic Japan Earthquake [9]

It's only in Japan because Japan has actually built the infrastructure required by putting thousands of seismographs around the country to detect early seismic waves (P-waves) that come before the main shaking (S-waves).

Until other countries install the sensors, they can't have a useful earthquake early-warning system.

Grammar, Usage / Have vs has? [4]

Hi, everybody. I just noticed form the Sesame Street that when we describe different parts of body, people tend to say " I have got a pair of eyes" rather than " I have a pair of eyes". Is there any difference between the two? And is it right or natural for us to say "I have". Just want to ensure I say it right and teach it right. Thanks a lot.
