For more than six million American children, coming home after school means coming home to an empty house. Some deal with the situation by watching TV. Some may hide. But all of them have something in common. They spend part of each day alone. They are called latchkey children. They’re children who look after themselves while their parents work. And their bad condition has become a subject of concern.

Lynette Long was once the headmaster of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was constantly telling them to put them inside shirts. There were so many keys, it never came to my mind what they meant.” Slowly, she learned they were house keys.

She and her husband began talking to the children who had them. They learned of the impact(影响) working couples and single parents were having on their children. Fear is the biggest problem faced by children at home alone. One in each three latchkey children the Longs talked to reported being scared. Many had nightmares and were worried about their own safety.

The most common way latchkey children deal with their fears is by hiding. It might be in a shower stall, under a bed in a closet. The second is TV. They’ll often play it at high volume. It’s hard to get statistics(情况, 材料)on latchkey children, the Longs learned. Most parents are slow to admit they leave their children alone.

A typical (160) language contains an applicative sub-language which approximates the mathematical abstractions of "timeless" functions applied to "spaceless" values, where the actual operation sequences and use of storage space during expression evaluation are organized behind the (161) . In this setting, values are data structures of low volume, typically a few computer words or less, which means that an illusion of spacelessness can be realized by having (162) results during expression evaluation stored at the discretion of the language implementation, and effecting parameter (163) and (164) operations through value copying.

A.imperative
