TUVALU, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up
by the sea. Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more
than five meters above sea level, Salt water is already entering the country's drinking water supply, as
well as damaging plants that produce fruit and vegetable. _1_
_2_. Venice, a historic city in Italy best known for its canals, has sunk about 24 cm over the past 100
years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark's Square,
the lowest point in the city, floodedd about nine times a year, Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, Tuvalu's rising sea level is caused by global warming.
The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it to rise by extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers melt, adding more water to the ocean. The warmer temperatures also
make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10－25 cm in the last 100 years.
_3_. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the
atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even
warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. _4_.
_5 , the sea will swallow up millions of homes and the world will be flooded with "climate refugees"
looking for somewhere to live.

| Gift Giving 1.______ There are many occasions (场合) for giving gifts in modern industrialized societies: birthdays, naming ceremonies, weddings, anniversaries, New Year. It is common to give gifts on many of these celebrations in western cultures. In addition, special events, such as one's first day of school or graduation from university, often require gift giving. 2.______ What is happening when we give gifts? Most important, we are exchanging gifts. If someone gives me a gift for my birthday, I know that I am usually expected to give one on his or her next birthday. A gift builds up or confirms a social obligation (义务). 3.______ Gifts tighten personal relationships and provide a means of communication between loved ones. People say that a gift lets the recipient (接受者) know we are thinking of them, and that we want to make the person "feel special." We want people to feel wanted, to feel part of our social or family group. We give presents to say "I'm sorry." Sometimes it is difficult for us to find a present that someone will like. Sometimes we give things that we like or would feel comfortable with. In all these cases, the gifts are sending out messages-often very expressive ones. 4.______ People tend to talk about presents in a fairly loving way. A woman whose mother had died years ago described the many gifts around her house. These were gifts that her mother had given her over the years:"I appreciate these, and they mean something to me," the woman said, "because I remember the occasions they were given on, and that they were from my mother, and the relationship we've had." The gifts remain and keep the relationship alive in mind. This woman felt the same way about the gifts she gave to others. She hoped that the recipients would look at her gifts in years to come and remember her. 5.______ Emotions (情感) like these suggest that a positive spirit still lies behind gift giving. They prove that the anthropologist Claude Levi-Strauss was wrong to say that modern western gift giving is highly wasteful. Studies in Canada and elsewhere have also shown that this is not the case. Each gift is unique even if so many are given. The emotional benefit for those who exchange gifts is the very reason for the tradition to continue. |
