.ALike many American people,I have a “bucket list”.It’s something along the lines of the “top-10-things-to-see-or-do-before-you-die” lists published on travel web sites.“Set foot on all seven continents” has always been on my list.This past February,after nearly six months of planning,I was fortunate to be able to knock off two—the most amazing being Antarctica,the other South America.I chose an optimal time to go—summer in the southern hemisphere(半球)—and found a tour company online that was able to accommodate my needs.It is a costly adventure,especially when travelling solo,but the company put together a package for me that was perfect.The company not only got me to the continent,but allowed me the opportunity to set foot on it.Many tour companies will put you on a ship that sails through the area,weaving between islands and giving views of the shore.But to actually set foot on the continent is a rare and impressive treat.One of the tour leaders on our boat estimated that the total number of people who have actually set foot on this land—tourists,scientists and explorers—would only fill a very large football stadium.This is because tourism to Antarctica didn’t really exist until roughly 15 years ago and has only recently taken off in popularity.There are also rules and restrictions for visiting set up by the International Association of Antarctica Tour Operators.Take nothing away,and leave nothing behind.My plan was simple.Arrive in Ushuaia,Argentina,and get on the M/V Orlova,an ice-strengthened Russian ship,to spend 10 days exploring Antarctica.We saw paradise in a frozen form.No traffic noise,no pollution,no road rage—just clear skies,fresh air and undisturbed beauty for miles.Months later,I still wish I could be there sitting with the penguins,taking it all in,smile firmly frozen in place.1.When the author started his travel,what season was it in America?A.Spring.B.Summer.D.Winter.“I chose an optimal time to go—summer in the southern hemisphere...”可知,作者是在美国是冬季的时候出发的。
