【题目】Types of Family Structures

Family structure has changed noticeably over the last 50 years. 1

Nuclear Family

The nuclear family is the traditional type of family structure, consisting of two parents and children. 2 Children in nuclear families receive strength and stability from the two-parent structure and generally have more opportunities due o the financial ease of two adults In America, almost 70 percent of children live in a nuclear family unit.

Extended Family

The extended family structure consists of two or more adults who are related, either by blood or marriage, living in the same home. This family includes many relatives living together and working toward common goals. 3 Extended families are becoming increasingly common all over the world.

Stepfamily

Many marriages end in divorce, and many of these individuals choose to get remarried. This creates the stepfamily which involves two separate families merging into one new unit. 4 Stepfamilies are as common as the nuclear family, though they tend to have more problems. Stepfamilies need to learn to work together to ensure these family units run smoothly.

【题目】 It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.

In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those“fortunate”few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dying compared to the seven-hour crowd.

The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation(适度).

You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology. Researchers discovered that even if a person sleeps more than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight and developing sensitivity to insulin, which controls the level of sugar in blood.

For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived(睡眠不足的) groups consume more food and gain weight.
