This Thursday is Thanksgiving Day. The writer O’Henry called it the one day that is purely American. Thanksgiving is not a religious holiday. But it has ritual meaning. Some Americans attend religious services on the day before Thanksgiving or on Thanksgiving morning. Others travel long distances to be with their families. They have a large dinner which is the main part of the celebration. For many Americans, Thanksgiving is the only time when all members of the family gather. The holiday is a time of family reunion. Thanksgiving week is generally one of the busiest travel times of the year. However, experts say this year probably will be different. On September 11th, thousands of people died when terrorists hijacked airplanes that struck buildings in Washington D.C. and New York City. Many people now say they are worried about flying on a plane. Travel experts say almost 6 percent fewer people will make long trips this Thanksgiving compared with last year. Many Americans who usually visit family and friends by plane are driving shorter distances instead this week. Some mental health experts say the attacks have frightened people. They say people feel safer and happier close to home. More than any other holiday, Thanksgiving is a celebration of family and home. Many people say that this year they are especially thankful for their families and friends and the good things in their lives. On Thanksgiving, people enjoy a long day of cooking, eating and talking. The traditional meal almost always includes the turkey with a bread mixture cooked inside. Other traditional Thanksgiving food served with turkey are sweet potatoes, cranberries and pumpkin pie. Stores are said to sell more food at Thanksgiving than at any other time of the year, and many people eat more food at Thanksgiving than at any other time of the year. Over the years, Americans have added new traditions to their Thanksgiving celebration. For example, a number off professional and university football games are played on Thanksgiving Day. Some of the games are broadcast on national television.

Nowadays, more and more people like to travel in their holidays. The other day I read a report about the ways people spend their holidays. It is reported that in recent yiars several new holiday habits have been developed. Among them, the most interesting one is the growth of the so-called holiday camps.

From the report we can see that in 20XX,40 percent of people stayed at home for holidays. But now the proportion has reduced to 9 percent. More people go out for fun. The proportion of camping and traveling abroad was increasing steadily, from 10 percent in 20XX to 38 percent in 20XX, and 12 percent in 20XX to 26 percent in 20XX respectively. People enjoy the fresh air, clean Water and green hills when they go camping in the suburbs. In 20XX,38 percent people enjoyed going to the seaside while in 20XX only 27 percent prefer to go there. What great changes!

Why did those changes appear? I think there are several reasons. First, it s because people can afford traveling. Second, people prefer to pursue a high-quality and colorful life. Third, their attitudes to relaxation have changed. Less people want to save much money by leading a simple life. In short, peoples living standard today has been rising greatly.

d happy holiday.

篇2:英语作文:旅游中的不文明行为

旅游中的不文明行为

随着人们生活水平的逐步提高,在中秋节、国庆节等假期中,越来越多的人选择出行旅游。一些富有人文历史、风景优美的景点,成为了大众的首选。

但是随着旅游人数不断增加,旅游中的不文明行为也不断增多。游客们随意攀爬、拍照,在景点随意涂画、刻、践踏草坪、损坏植被,不讲卫生,垃圾随处丢弃。旅游中的不文明现象,正持续损害着中国游客的形象。

我认为文明旅游可以注重以下一些方面:首先,旅游者要提高自身文化素质,做到文明出行,不做一些破坏文化的行为,并且及时提醒他人的不文明行为。第二,导游、景点管理处要对旅客不文明的行为加以提醒劝阻。第三,媒体应加大曝光度,使人们逐渐意识到不文明旅行的严重性。最后政府要根据旅客的行为实施一定的惩罚措施,完善相关法律法规。我相信这些问题都会逐步解决,一个美丽的明天在等着我们。

Uncivilized behavior in Tourism

With the gradual improvement of peoples living standards, more and more people choose to travel during the holidays. Many people choose the humanities history and scenic spots to travel.

But with the increasing number of tourists, the uncivilized behavior of tourism is

increasing. Visitors free climbing, take pictures, in spots random graffiti, lettering, damage to vegetation, dont speak hygiene, waste discarded everywhere. Uncivilized phenomenon in tourism, is continuing to damage the image of Chinese tourists.

I believe that the cultural tourism can focus on the following aspects: first, tourists should improve cultural quality, do civilized travel, dont do some damage to the culture, and timely reminder of the uncivilized behavior of others. Second, the tourist guide and the scenic spot management office should discourage the uncivilized behavior of tourists. Third, the media should increase the degree of exposure, so that people gradually realized the seriousness of the

uncivilized travel. Finally, the government should implement some punitive measures according to the behavior of the passengers, improve the relevant laws and regulations. I believe that these problems will be solved step by step, and a beautiful tomorrow is waiting for us.

Going abroad for Studies

The other day I announced that I would go abroad for further studies right after my college education. My decision evoked the immediate objection of my family: Why? Why should I borrow a huge sum of money for overseas studies while I might receive the same education at home at relatively low cost? My answer is: in addition to knowledge, I can gain experience that those who stay at home will never have.

First, experience is the opportunity for the real-life use of foreign languages. While a person can study a foreign language at home, the effect can never be compared with constant use of the language in academic and everyday life. There is no better opportunity to improve second-language skills than living in the country in which it is spoken. Living in English-speaking countries such as America and Australia for several years, for example, my English will be as perfect as native speakers.

Second, living and studying abroad offers me a different perspective of the world. On a university campus, foreign students are likely to encounter their counterparts from different countries and areas and are exposed to different ideas and values. This helps me to have a meaningful understanding of different societies and inevitably sees my own country in a new light.

Third, overseas experience, frustrating and painful as it may be, is helpful. A person going abroad for study often experiences much more difficulty——difficulty in adapting to a new culture and in dealing with all problems alone. Yet, the difficulty, coupled with the frustration brought on by culture shock, is a rewarding experience for ones future life and development of personality.

Although going abroad is expensive and perhaps painful, the payoff is worthwhile. For the benefit is not merely knowledge gained, but the experience desirable in ones personal life.
