Yet，American women still try to protect their rights and to achieve equal high－level positions as men.

The divorce rate (离婚率) in the US is high. About one in three marriages ends in divorce. Single motherhood is also common. Three out of ten American households are headed by women. More than 25% of American children live with just one parent，usually their mothers，and 6% live with their grandparents.

By 2030，one in four Americans (more than 89 million people) will be over 60 years old. The growing senior population is putting pressure on the American government to increase funding for homes for the aged and health care for seniors.

The car is very important to the American lifestyle. Families use their cars to go to and get back from work and to go on holiday. They can do their banking，pick up a meal and even get married without leaving their cars. For many Americans，traveling on the open road means freedom. The rise in pollution has resulted in changes to car choices. Americans don't want to give up their cars，so they are now choosing smaller and more efficient cars.
