1.The movies just wouldn't be the same without the warm buttery taste of popcorn(爆米花).Amazingly,this delicious treat started its life as a corn kernel(玉米粒)---and not from just any corn.Popcorn is a type of sweet corn that was originally grown in Mexico and spread to China,India and elsewhere.It is the only kind of corn that will pop.Today,most of the world's popcorn is grown in the United States.
Every popcorn kernel contains a tiny drop of water,surrounded by soft starch (淀粉).When the popcorn is heated,the water turns into steam.This puts pressure on the surrounding hard kernel,forcing it to explode.The soft starch increases about 40times in size as the corn kernel turns itself inside out.
In the 1500s popcorn was an important food source for the Aztec Indians of central and southern Mexico.But it wasn't only food.It was also used in ceremonies or on red dresses and in necklaces.By the time the Europeans arrived in America,popcorn had spread through most of the American Indians.
Some early American settlers ate popcorn with cream and sugar for breakfast.But it wasn't until the late 1800s that popcorn became popular.The demand for popcorn increased and farmers began farming popcorn.The first mobile popping machine was invented in 1885,and popcorn was sold by street sellers much like hot dogs that are sold today.
During the Great Depression of the 1930s,the popcorn business still thrived as people could still afford it.Then in the 1950s television arrived and popcorn consumption decreased.People stayed home and stopped going to the theatre.But the link between movies and popcorn had already existed.Soon people began making popcorn at home on the stove and,later,microwave popcorn was introduced.
Today the movies have regained popularity and popcorn has once again become the favorite.

分析 短文主要对玉米的来源和其重要性.
解答 32.D,细节理解题,根据句子Popcorn is a type of sweet corn that was originally grown in Mexico 可知,玉米最开始是种植在墨西哥,故答案为D.
33.B,细节理解题,根据句子When the popcorn is heated,the water turns into steam.This puts pressure on the surrounding hard kernel,forcing it to explode.可知,玉米粒内的水并不能直接导致它炸开,而是水蒸气产生的压力作用于四周坚硬的内核上,造成它爆炸.故答案选B.
34.A,细节理解题,根据句子But it wasn't until the late 1800s that popcorn became popular.The demand for popcorn increased and farmers began farming popcorn可知,是在19世纪末期,随着人们对爆米花需求的增长,农民们才开始种植这种玉米.
35.D,词义猜测题.根据上文的still以及下文的as people could still afford it可推断出,这里指即使是在经济大萧条时期,因为爆米花仍然是人们买得起的食品,所以爆米花产业仍然发展得很好.
