Several recent studies have found that being randomly (随机地) assigned to a roommate of another race can lead to increased tolerance but also to a greater likelihood (可能性) of conflict.

Recent reports found that lodging with a student of a different race may decrease prejudice and compel students to engage in more ethnically diverse friendships.

An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure.

In a New York Times article, Sam Roakye-the only black student on his freshman year floor-said that \

Researchers also observed problems resulting from pairing interracial students in residences.

According to two recent studies, randomly assigned roommates of different race are more likely to

Global warming is causing more than 300,000 deaths and about $125 billion in economic losses each year, according to a report by the Global Humanitarian Forum, an organization led by Kofi Annan, the

7

former United Nations secretary general.

The report, to be released Friday, analyzed data and existing studies of health, disaster, population and economic trends. It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition (营养不良) and heat-related health problems.

But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions.

Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries, were being seriously affected by climate change. It projected that the number would double by 2030.

Roger Pielke Jr., a political scientist at the University of Colorado, Boulder, who studies disaster trends, said the Forum's report was \a methodological embarrassment\because there was no way to distinguish deaths or economic losses related to human driven global warming amid the much larger losses resulting from the growth in populations and economic development in vulnerable (易受伤害的) regions. Dr. Pielke said that \the report, he said, \deeply flawed (有瑕疵的)\

However, Soren Anderasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.

In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability to climate hazards, while still curbing the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report. 62. What is the finding of the Global Humanitarian Forum?

A) Global temperatures affect the rate of economic development. B) Rates of death from illness have risen due to global warming.

C) Malnutrition has caused serious health problems in poor countries. D) Economic trends have to do with population and natural disasters. 63. What do we learn about the Forum's report from the passage? A) It was challenged by some climate and risk experts. B) It aroused a lot of interest in the scientific circles. C) It was warmly received by environmentalists. D) It caused a big stir in developing countries.

64. What does Dr. Pielke say about the Forum's report? A) Its statistics look embarrassing. B) It is invalid in terms of methodology. C) It deserves our closest attention. D) Its conclusion is purposely exaggerated.

65. What is Soren Andreasen's view of the report?

A) Its conclusions are based on carefully collected data.

B) It is vulnerable to criticism if the statistics are closely examined. C) It will give rise to heated discussions at the Copenhagen conference. D) Its rough estimates are meant to draw the attention of world leaders.

66. What does Kofi Annan say should be the focus of the Copenhagen conference?

8

A) How rich and poor regions can share responsibility in curbing global warming. B) How human and economic losses from climate change can be reduced. C) How emissions of heat-trapping gases can be reduced on a global scale. D) How rich countries can better help poor regions reduce climate hazards. Part Ⅴ Cloze (15 minutes)
