学一个词：日全食 total solar eclipse (ZT)
A full solar eclipse is expected to occur on Wednesday. And the General Office of the State Council has urged relevant departments to make preparations to tackle any possible inconveniences or adverse effects caused by the eclipse.
本周三（7月22日）将出现日全食奇观。国务院办公厅要求各有关部门做好准备以应对任何可能由日食引发的任何不便或不利影响。
上面的报道中，
solar eclipse是“日食”，
full solar eclipse 就是大家都在期盼的“日全食”，也写做total solar eclipse。
日食是相当罕见的现象，一共有四种，
分别为total solar eclipse（日全食），
annular solar eclipse（日环食），
hybrid solar eclipse（全环食）
以及partial solar eclipse（日偏食）。
这些现象只在月球运行至太阳与地球之间时发生。这时，对地球上的部分地区来说，月球位于太阳前方，因此来自太阳的部分或全部光线被挡住，因此看起来好像是太阳的一部分或全部消失。
去年2月份，我们经历了total lunar eclipse（月全食）的壮丽景象，这一次的日全食相信会是更加激动人心的场面。

Longest 21st century solar eclipse envelops Asia in darkness (ZT)
A total solar eclipse began its flight on Wednesday across a narrow path of Asia, where it was expected to darken the skies for millions of people for more than six minutes in some places.
The longest total solar eclipse of the 21st century will be visible in a roughly 250 km-wide (155 miles) corridor, according to the US space agency NASA, as it travels half the globe and passes through India and China.
The eclipse began at 5:28 am local time (2358 GMT) in India and will last up to a maximum of 6 minutes, 39 seconds when it hits the Pacific Ocean, according to NASA.
Eclipses allow earth-bound scientists a rare glimpse at the sun's corona, the gases surrounding the sun.
Starting on India's west coast north of financial capital Mumbai, it took in the ancient Hindu holy city of Varanasi on the Ganges river.
Tens of thousands of people snaked through the narrow lanes of Varanasi and gathered for a dip in the Ganges, an act considered to lead to salvation from the cycle of life and death.
Amid chanting of Hindu hymns, men, women and children waded into the river with folded hands and prayed to the sun as it emerged in an overcast sky.
"We have come here because our elders told us this is the best time to improve our after-life," said Bhailal Sharma, a villager from central India, who came to Varanasi with a group of about 100 people.
The eclipse was due to sweep through Bangladesh, Nepal, Bhutan, Myanmar and China's financial hub Shanghai, before heading to the Pacific.
"In the 21st century this is the longest," said Harish Bhatt, dean at the Bangalore-based Indian Institute of Astrophysics.
"This is indeed quite an important event for scientific experiments. Its long duration provides you an opportunity to make very complicated, complex experiments."
