题型描述: 阅读理解Halloween(October 31) This is a holiday widely celebrated with different names in many countries. Although it originated as a religious holiday, it has lost its religious connections in theUnited States. It is now celebrated largely as a children's day, and many American children look forward to it for days and weeks beforehand. The orange pumpkin is harvested at this time of year and is hollowed out, a funny face cut into it, and a candle placed inside as a decoration in the window. City folks, nowadays, sometimes use paper pumpkins for decorations. Some years ago, the holiday was celebrated by dressing up in strange and frightening costumes and playing tricks on one's neighbors and friends, such as ringing door bells, throwing bits of corn on the window panes, and in other ways making minor disturbances. More recently, children come to the door to have friends and neighbors admire their costumes and guess who they are behind the false faces and receive treats of candy, fruit or cookies. They say, “Trick or Treat", meaning, “I will play a trick on you will not give me a treat." This practice has even more recently developed into a significant international activity. Instead of or along with candy, the children collect money for UNICEF (United Nations International Children's Emergency Fund). This special collection of money by children for needy children throughout the world is known as “UNICEF Trick of Treat". Begun only recently, it results in several million dollars each year contributed to UNICEF. The collection box is orange, reminiscent of the pumpkin.英语阅读I
