The consequences of working irregular hours vary according to gender, economic level, and whether or not children are involved. Single mothers are more likely to work nights and weekends than married mothers. Women in clerical, sales, or other low-paying jobs participate disproportionately in working late and graveyard shifts.
Married-couple households with children are increasingly becoming dual-earner households, generating more split-shift couples. School-aged children, however, may benefit from parents' nonstandard work schedules because of the greater likelihood that a parent will be home before or after school. On the other hand, a correlation exists between nonstandard work schedules and both marital instability and a decline in the quality of marriages.
Nonstandard working hours mean families spend less time together for dinner but more time together for breakfast. One-on-one interaction between parents and children varies, however, based on parent, shift, and age of children. There is also a greater reliance on child care by relatives and by professional providers.
Working nonstandard hours is less a choice of employees and more a mandate of employers. Presser believes that the need for swing shifts and weekend work will continue to rise in the coming decades. She reports that in some European countries there are substantial salary premiums for employees working irregular hours—sometimes as much as 50% higher. The convenience of having services available 24 hours a day continues to drive this trend.
Unfortunately, says Presser, the issue is virtually absent from public discourse. She emphasizes the need for focused studies on costs and benefits of working odd hours, the physical and emotional health of people working nights and weekends, and the reasons behind the necessity for working these hours. "Nonstandard work schedules not only are highly prevalent among American families but also generate a level of complexity in family functioning that needs greater attention, " she says.
Which of the following demonstrates that working at nonstandard times is taking its toll on American families？

听力原文： What is cloning？ Cloning is the creation of cells or whole animals using DNA from a single "parent", by passing the normal reproductive process. The clone has the same DNA as the parent.
The most common process takes DNA from one cell and puts it in a hollowed-out egg. Chemicals and electricity are then used to encourage the new DNA to fuse with the egg and develop into an embryo. This technique is called nuclear transfer.
The first cloned animal in human history is a sheep called Dolly. It is very important because it was the first mammal to be cloned using DNA taken from an adult cell. Previously, animals had only been cloned using embryo cells, which already have the potential to become a complete embryo in its own right. The big breakthrough with Doily was to make a clone from an ordinary, adult cell.
When it comes to the question of whether cloned animals are normal and healthy, the answer is YES. Doily is, but scientists do not yet know whether this is the exception or the rule. Some early evidence suggests that clones may have health problems and that they may age prematurely.
With the birth of Dolly, many people are worried that a human clone may be born soon. It's possible in theory. But the technology of reproductive cloning is still in its very early stages and there is much that scientist do not understand. That's more, human cloning is already banned by law in the United Kingdom. The former President of the United States Bill Clinton proposed banning research in to producing human clones in the US for five years. Some measures have also been taken to establish international agreements banning live human clones.
