When it comes to Thanksgiving, turkey may be the first thing that comes to mind. It’s the right picture, but it’s not complete. Celebrated on the fourth Thursday of November every year, Nov. 28 this year, Thanksgiving Day is about expressing your gratitude to the important people and all the good things in your life. Americans celebrate Thanksgiving with much fervor and maintain many traditional customs. Here we introduce a few of the rituals Americans typically follow on this day.
小題1:_________________
Thanksgiving Day has been associated with communal prayers in church and in homes for centuries. Attending church services in the morning is the first step of many celebrators on Thanksgiving Day. The churches provide worship services and organize special events for the occasion. Before Thanksgiving meals, some families gather together and thank God for his kindness and the gifts he has bestowed upon them in the form of friends and family. Some people also do voluntary community work on this day, as a way of contribution.
小題2:_________________
Like China’s Spring Festival, preparing a big meal and bringing the family together at home is a long-standing tradition of Thanksgiving. Distances don’t really matter as relatives return home to be with their family, no matter how far away.
Undoubtedly, turkey is the main course of Thanksgiving dinner. Though there is no evidence to prove that turkey was eaten during the first Thanksgiving dinner, most agree that the dinner would be incomplete without it. Other dishes typically found on dinner tables in almost every house are pumpkin pies, corn, fall vegetables, olives, cranberry sauce, stuffing and mashed potatoes. At the meal, many families observe the ritual of taking turns to express what each member is thankful for.
小題3:_________________
While feasts make Thanksgiving a festival for individual families, parades make it a carnival for the whole nation. Various parades are held in many cities to honor Thanksgiving. One of the largest is New York’s Thanksgiving Day Parade, which is currently called Macy’s Thanksgiving Day Parade. Started in 1924, more than 2 million people attend the parade every year.
Important features of the parade are themed floats, scenes from Broadway plays, large balloons of cartoon characters and TV personalities, and high school marching bands. The parade traditionally ends with a Santa Claus float, which marks the unofficial beginning of the Christmas season.
小題4: __________________
After-dinner rituals are just as important as the meal itself, and no after-dinner ritual is more important than the football game. The US’ National Football League has played a special game on Thanksgiving every year since its creation in 1920 (with the exception of 1939-1944 due to World War II). It’s referred to as the Thanksgiving Classic, and thousands of fans watch it with popcorn and chips in hand, either in stadiums or on television.
In 1863, a reporter jokingly said, “Thanksgiving is a holiday granted by the Nation to see a game of football.” It’s absolutely true.
小題5:_________________
While Chinese citizens enjoy an online shopping spree on Nov 11, Americans flock to physical stores just after Thanksgiving. The Friday after Thanksgiving Day is famously known as “Black Friday” because of the standard accounting practice of writing profits in black.
Many employers give their employees the day off as part of the Thanksgiving holiday weekend, so retailers seize the opportunity to offer discounts and put items on sale. Hundreds of thousands of people take advantage of the opportunity to hunt for bargains. The sight of people waiting in long lines for shops to open on the morning after Thanksgiving Day is quite normal.

閱讀下面的短文,在標有序號的空白處填入一個適當?shù)脑~,或填入括號中所給單詞的正確形式。
Language follows power. In an increasingly globalized world, some languages become the kings in terms of trade and communication. They jump geographic boundaries, pushing smaller languages toward    小題1: .
According to National Geographic magazine, one language dies every 14 days. By the next century nearly half of the roughly 7,000 languages spoken on Earth are   小題2:  to disappear as communities abandon native tongues in favor of English, Mandarin or Spanish.
This is    小題3:   Google.org is launching a new campaign called the Endangered Languages Project. It aims to digitally record the world’s little-known tongues and the heritages to which they are central.
What kind of languages are disappearing? Languages like Arogonese, which can be found in northern Spain, for example. Spoken by fewer than 10,000 people, this language seems to    小題4:   (disappear) within a few generations. Navajo and Ojibwa, both native to the Americans, are also close to extinction. Koro is the native language of a small population   小題5:  in the mountains of northeast India. It’s spoken by about 4,000 people.
The Endangered Languages website will record roughly 3,500 of the world’s little-spoken tongues. “  小題6:  every language that dies, humans are in danger of losing an enormous cultural heritage”, writes Loek Essers on the website Computerworld.com.
“As each one disappears, an understanding of how humans relate to the world around them, as well as scientific, medical, and botanical(植物的)knowledge, are all lost,    小題7:   is the expression of a community’s humor, love, and life.”
Users of the website can find    小題8:   which can be identified by their location on a map, or reached by means of a list that has been broken down into four categories: at risk, endangered, severely endangered, or unknown.    小題9:   can upload video or audio samples as well as share their knowledge of a language.
“Languages are alive and in constant change, and their extinction is not new,” write the site’s creators. “  小題10:   today we have the tools and technology that could become a game changer.”
