hemisphere 【HEMISPHERE】North America and South America are in the Western Hemisphere. 北美洲和南美洲都在西半球。【重点词汇】hemisphere n. 半球

Accepted Answer

['hemɪsfɪr] 
hemispherehalf of a sphere
A hemisphere is half of a sphere. If it’s a cold winter in the northern hemisphere, take a winter getaway to sunbathe somewhere in the southern hemisphere.
Hemisphere comes from the Greek, and combines the prefix hemi-, for "half," with sphere, or "perfectly round ball." We talk about the earth as divided at the equator into the northern and southern hemispheres (or divided at the prime meridian into eastern and western hemispheres). In biology, there are two cerebral, or brain, hemispheres — also known as the right and left sides of the brain.
