What may cause obesity
The passage talks about the reasons for obesity in America.

(2) Can you guess the meaning of ‘screenagers’
(3) Look at the picture nearby, what is supersized
There are four reasons. They’re car culture, screenagers, fast food and supersizing.
It is a combination of the word “screen” and “teenager”, so it may mean the teenagers who spend lots of time in front of the screens.
We can see the picture of popcorn, so maybe the food is supersized.
Paragraph 1
(1) What is the car culture in America
(2) How does it contribute to obesity

Screenager
A typical American family has three TVs.
The average teenager watches 22 hours of television every week.
The average US home has 24 electronic gadgets.
Watching TV and using electronic gadgets make kids inactive and become couch potatoes. These inactive kids are at greater risk of becoming obese adults.
Phenomenon Detail Contribution to obesity
Fast food
50% of meals are eaten outside home and more than three quarters of American teenagers eat a fast food meal at least once a week.
Americans eat fast food more often as they have less time to cook. However, fast food with a lot of fat and sugar, tends to make people overweight.

Supersizing
Movie watchers didn’t want to look greedy when they bought popcorn, but they didn’t mind buying a supersized bag of popcorn.
Food companies encourage Americans to consume more food by supersizing the portions of food.
As a result, people’s calorie consumption has risen significantly and Americans tend to become fat.
