Every day, thousands of tourists from around the world plan their trips to the Great Wall of China.

Despite the wall’s 5,500-odd miles,     1     (spread) from east to west across the country, most travelers find     2     (them) at either the Badaling or Mutianyu sections, the two areas closest to Beijing. These visitors rise early from their downtown hotels, pack themselves into buses and wait in long queues     3     (see) the magnificent structures that consist of the Great Wall.

But what if there was another way?

An hour-long drive north of the     4     (crowd) capital is Commune by the Great Wall, a popular weekend getaway for Beijingers     5     a series of modern buildings consist of a luxury hotel, with award-winning design among yellow-leaved gingko trees. It is not only the rural surroundings     6     attract travelers to the town of Yangqing. Beyond the usual services — an expansive breakfast buffet and cozy bed sheets — Commune by the Great Wall     7     (provide) a rare opportunity to simply walk to the Wall. Just 20 minutes by foot from the hotel reception     8     (be) the Shuiguan section of the wall.

Commune by the Great Wall won     9     special praise at the Venice Architecture Biennale in 2002, the year the 12 core buildings     10     (complete).

Back in    1    late 1700s, long before people understood the reason behind immunity (免疫),farmers and doctors in rural areas of Britain noticed that dairymaids(牛奶工) and other people who got a mild disease called cowpox(牛痘) seldom caught its fearsome cousin, smallpox (天花). Was there a connection? Some decided there was an inserted (植入) material from the cowpox into an incision (切口) they cut on the arm of healthy people, thus somehow     2    (protect)them from smallpox. In 1798,a doctor named Edward Jenner published the results of his experiments using this procedure,earning     3    (he)fame as the“Father of Smallpox Vaccination (疫苗接种).”

Scientists later figured out that cowpox somehow protected one from smallpox. When people caught cowpox, their bodies made special cells     4     (call) antibodies. They fought the disease.That's not all. They stayed in the blood       5    case the disease ever returned. Because cowpox and smallpox are fairly similar, if a person was later exposed to the more serious disease, anti-bodies were ready     6    ( fight) it too.

That knowledge helped scientists develop vaccines. The term vaccination was coined from the Latin for cow (vacca).They contain the virus, weakened, dead or modified (改良的) . Injected into the blood, they trick the immune system into making antibodies.    7     the body ever meets with those same    8    (virus),even at full strength,the antibodies make short work of them.

Vaccination prior to     9    (expose) to the virus is ideal. But a vaccination given within three days of exposure will     10    (complete) prevent or significantly modify smallpox in the majority of people and given within the first four to seven days will likely offer some protection or soften the diseases.
