Tiny water plants called phytoplankton (浮游植物) serve as food for many sea creatures, including whales, shrimp, jellyfish and snails.
Phytoplankton do well in cold water. But if water temperatures rise by only two degrees Celsius, the phytoplankton struggle. That is what happened in the last three or four years in the northern part of the Pacific Ocean. Researchers say an unusual area of warm water spread throughout the Northern Pacific. Scientists called the warm water ''the blob'', as if it were a character in an old science fiction movie. At its largest, the blob stretched 1,600 square kilometers and reached depths of 91 meters. This large mass of warm water had a damaging effect on the ocean food chain. Many fish that depend on phytoplankton swam away from the area. As a result, sea birds and sea lions that eat those fish starved.
Scientists from the National Oceanic and Atmospheric Administration and the University of Washington have found that the warm ocean ''blob'' caused a harmful algae bloom. That fast growth in algae hurt fishing grounds along the U.S. West Coast and Canada's British Columbia. The researchers recently published their study in the journal Geophysical Research Letters. They looked at the algae, called P. australis. They found that the algae can grow much faster than normal if it is exposed to warm water. The higher levels of algae also produced more of a poisonous chemical that can cause problems for everything from shellfish to dolphins to sea lions. It also causes problems for humans if too much of the chemical builds up in their blood.
Researchers say algae blooms like this one will continue as ocean waters warm. The algae will hurt sea animals, birds, and fish. It may damage food resources for humans all over the world, the scientists say.
1.The root cause of the starvation of sea birds or sea lions is_____.
A.the depths of the vase sea
B.the large mass of warm water
C.the large amount of polluted sea water
D.the increasingly reduced phytoplankton in the sea
2.From the text, we can know that P. australis is the name of a(n) _____.
A.phytoplankton B.fish
C.algae D.bird
3.The following statements are true EXCEPT_____.
A.Generally, the algae grow much faster than normal if exposed to cool water.
B.The phytoplankton is very sensitive to the rise of water temperature.
C.More algae can bring about a poisonous chemical which endangers sea creatures.
D.Algae blooms will affect not only the existence of sea creatures but also that of humans the world over.
4.The text is most probably taken from_____.
A.a research paper B.a geography textbook
C.a class presentation D.a newspaper report

Food serves as a form of communication in two fundamental ways. Sharing bread or other foods is a common human tradition that can promote unity and trust. Food can also have a specific meaning, and play a significant role in a family or culture's celebrations or traditions. The foods we eat—and when and how we eat them—are often unique to a particular culture or may even differ between rural and urban areas within one country.
Sharing bread, whether during a special occasion or at the family dinner table, is a common symbol of togetherness. Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests. Early forms of cake were simply a kind of bread, so this tradition has its roots in the custom of sharing bread.
Food also plays an important role in many New Year celebrations. In the southern United States, pieces of corn bread represent blocks of gold for prosperity in the New Year. In Greece, people share a special cake called vasilopita. A coin is put into the cake, which signifies success in the New Year for the person who receives it.
Many cultures have ceremonies to celebrate the birth of a child, and food can play a significant role. In China, when a baby is one month old, families name and welcome their child in a celebration that includes giving red-colored eggs to guests. In many cultures, round foods such as grapes, bread, and moon cakes are eaten at welcome celebrations to represent family unity.
Nutrition is necessary for life, so it is not surprising that food is such an important part of different cultures around the world.
1.According to the passage, sharing bread______.
A. can help to develop unity
B. indicates a lack of food
C. is a custom unique to rural areas
D. has its roots in birthday celebrations
2.What does the coin in vasilopita signify for its receiver in the New Year?
A. Trust. B. Togetherness.
C. Health. D. Success.
3.The author explains the role of food in celebrations by______.
A. analyzing causes B. making comparisons
C. using examples D. describing processes
4.What is the passage mainly about?
A. The custom of sharing food.
B. The importance of food in culture.
C. The role of food in ceremonies.
D. The specific meaning of food.
