About 1 million adult New Yorkers are obese(肥胖的), but nearly two-thirds of them don’t think they are, according to a study released on Tuesday by the city’s Department of Health and Mental Hygiene(衛(wèi)生).

    Among the obese, who account for about one in five New Yorkers, only 39% described themselves as “very overweight”, according to the report. 2% said they were very underweight, 1% said they were slightly underweight, 16% said they were just right and 42% said they were slightly over weight.

     Some 2 million more New Yorkers are overweight, the report said, and one in five children in kindergarten is obese.

     Only 44% of the city’s adults are at a healthy weight, and nearly 75% say they do not participate in(參加) any regular physical activity.

     New York City’s adult obesity rate was 20% in 2003 compared with 23% nationwide in 2004.The national average has nearly doubled from 12% in 1993, the report said.

    Overweight and obese are defined by body mass index, or BMI (= kg/m) , which is based on a person’s weight , adjusted(調(diào)整) for height, the department said.

    Being obese means having a BMI of 30 or greater, while being overweight means a BMI of more than 25 but less than 30.

    A 5-foot, 10-inch (1.78-meter) man weighing 175 pounds(79kg) would have a BMI of 25.1 and be considered overweight according to the department . If he weighed 210 pounds (95kg), he would have a BMI of 30.1 and be obese.

    The report came from results of the department’s 2002 and 2003 yearly telephone surveys of some 10,000 adults.

New York City has a population of about _____ according to the passage.

  A.5,000,000  B. 2,000,000  C. 1,000,000 D. 500,000

We can infer from the passage that ____.

  A. most adult New Yorkers go in for many regular physical activities

  B. New Yorkers think that obesity shows economic development

  C. New York City’s adult obesity rate increased from 1993 to 2004

  D. most of the New York City’s adults are at a healthy weight

If a 1.75-meter-tall man weighs 99 kilograms, he is ____ according to the passage.

   A. overweight    B. underweight   C. slightly underweight    D. obese

What is the passage mainly about?

   A. Population explosion in USA.

The Antarctic Icecap is the largest supply of fresh water，representing nearly 2％of the world’s total of fresh and salt water. As can be seen from the table below, the amount of water in our atmosphere is over 10 times as much as the water in all the rivers taken together. The fresh water actually available for human use in lakes and rivers and the accessible ground water amount to only about one-third of 1％of the world’s total water supply.
