Barack Obama, the US President-elect, is busy choosing members of his cabinet. His daughters, Sasha and Malia, are busy, too. They are making difficult decisions about different dog breeds (品种).

“The girls asked when we got in this race that [whether] win or lose, we get a dog,” said Michelle Obama. “So we will be welcoming a four-legged friend to our house.”

No matter what type of puppy Sasha and Malia pick, it will be a part of a long story of White House pets. Everything from snakes to bears has lived at the White House with the president and his family.

Calvin Coolidge, the 30th president, kept a pet raccoon (浣熊). Warren Harding had turkeys. William Howard Taft parked his cow in the White House garage too.

John Quincy Adams, the sixth president, had a pet alligator (鳄鱼). But he wasn’t the only White House resident to have one. Herbert Hoover’s son had two pet alligators, and they were sometimes allowed to roam (闲逛) around the White House.

Bears have also been popular with American presidents. While Thomas Jefferson kept two grizzlies (灰熊) in a cage, Theodore Roosevelt had a black bear. Roosevelt’s interest in bears later led to the creation of the toy teddy bear.

Roosevelt and his six children loved animals, and they filled the White House with them. They had dogs, cats, squirrels (松鼠), raccoons, rabbits, guinea pigs, a badger (獾), a rat, a parrot, and a green snake.

根据上面短文的内容填空                           

1. ________ and ________ have difficulty in choosing different kinds of dogs.

2. The four-legged friend refers to ________ according to Michelle Obama’s ________.

3. ________ Adams, Herbert Hoover’s son liked keeping alligators ________ his pets

4. The ________ of the toy teddy bear ________ from Roosevelt’s interest in bears.

5. Roosevelt is the ________ of six ________.
