Obesity (肥胖症) is becoming a problem in our busy society, and almost one in three American adults is now
considered to be obese. Children obesity is alsoat an all-time high.
Obesity means being very overweight. If you are obese, you have too much bodyfat. If you eat more food
than your body can use, this will make you put on weight. Food that your body does not need will be stored as fat
by your body.
The following are the major factors that increase the risk of obesity.
What you eat plays a major role in weight gain. Eating a lot of fast food such as hamburgers, sweet drinks, ice
creams and other sweet food can increase the risk of becoming obese.
If you do not do enough exercise, you will put on weight as the food you eat is not being used to make energy
for physical activities.
The chances of you being obese are greater if your parents are obese.
There are many psychological factors that cause people to eat too much. People who are worried, unhappy or
bored will often eat to make themselves feel better. This is known as comfort eating.
Age is another factor, as you tend (趋于) to be less active when you get older. When you get older, you need
to eat less, and if you do not eat less, you will put on weight. Obesity can cause many health problems such as
heart problems, high blood pressure and many other serious medical conditions.

Once small farmers in Masii, a remote village in Kenya, have picked their crops, all they can do is wait until a
buyer trucks through. The system works fairly well for beans and corn, but mangoes-the area’s other main
crop-spoil (腐烂) more quickly. If the trader is late, they rot.
However, a simple coating could change that. A company, SmartTech, has created a product that doubles the
shelf life of fresh produce, enabling farmers to access far-off, larger markets. More time forfresh produce on
grocers’ shelves also means less food waste-a $2.6 trillion problem, according to the United Nations’ Food and
Agriculture Organization (FAO).
James Rogers, CEO of SmartTech, wanted to solve the problem for food much in the same way that oxide
barriers preventing rust (锈) have achieved for steel. Fortunately, researchers have found when plants made the
jump from water to land, they developed cutin(蜡质), a barrier which is made of fatty acids that link together to
form a seal around the plant, helping keep water in.
The cutin was such a grand strategy that today you’ll still find it across the plant kingdom. SmartTech
discovered through researches that an orange can last longer than a strawberry not so much because of the
thickness of its skin, but because of the difference in the arrangement of those cutin molecules (分子)on the
surface. After extensive trials, Rogers and his team developed a natural and tasteless protective coating from plant
material-stems, leaves and skins. The product extends the sweet spot between ripening and rot. And best of all,
the treated produce doesn’t require refrigeration.
“SmartTech has huge potential to turn poor farmers in Africa into commercial farmers,” says Rogers. “That
means more money in pockets, and more food in stomachs.” But whether the company can cost-effectively reach
small farmers in far-off areas still remains a challenge.
4. The author mentions the small farmers in Kenya to ________.
A. stress their need for preserving produce
B. show their challenge in harvesting crops
C. express their wish to reach larger markets
D. evaluate their loss caused by slow transport
5. What can we learn about SmartTech’s product? A. It is financially supported by FAO.
B. It is intended to replace refrigeration.
C. It is designed to thicken produce’s skin.
D. It is based on plants’own defence system.
6. What will James Rogers probably focus on next?
A. How to expand farms.
B. How to earn more money.
C. How to produce more tasty food.
D. How to profit farmers in remote area.
7. The main purpose of the passage is to ________.
A. promote a product B. present a technology
C. advertise SmartTech D. introduce James Rogers
C
