But only a narrow strip of the country more than 110 kilometers wide through 14 states will experience a total eclipse
此次日食将形成一条宽度约为110公里的“日全食带”，横跨美国的14个州，这些州可观测到日全食，
in which the sun will be completely obscured by the moon.
即太阳完全被月球遮蔽。
The rest of the country will see a partial eclipse, here in Washington D.C.,people will see about 80 percent of totality.
