What are the advantages and disadvantages of eating fast food?

Many people do not have time to eat home-cooked food.     1     There’re more than 13,000 McDonald’s restaurants in the United States itself, and over 8,000 KFCs in 80 countries. In most cities, it is not difficult to find hamburgers and pizza.

Advantages of fast food

    2     Eating fast food helps working people and students to get back to work as quickly as possible. Besides, many love the look, smell and taste of it. Perhaps the greatest advantage is the price.

    3     If one lives alone, then it is cheaper to buy a meal at the supermarket than cook it at home.

Disadvantages of fast food

The greatest disadvantage of fast food is the bad effect that it has on one’s health. Many people feel that fast food is unhealthy because it contains a lot of artificial ingredients (人造成分). Some even think that it is addictive (上瘾的) because of these ingredients.     4     Fast food may cause overweight in the American population.

    5     I believe that it can be a good thing, as long as people do not eat it too often, eat plenty of fruit and vegetables, and also do plenty of exercise to keep in shape.

Science has also found amazing ways to keep people healthy. Nanotechnology（纳米技术） can help cure（治愈） many illnesses, including cancer. And if any part of your body is unhealthy, you can “grow” a new one in a laboratory（实验室）.

On the way to the kitchen, you want to call a friend. Your cell phone is by the window because it gets its energy（电量） from the sun. But you don’t need to pick up the phone. You can just touch your jacket sleeve to make the call.

It’s breakfast time. You reach for the milk, but a voice says, “Don’t drink that!” Your fridge knows the milk is old, and tells the supermarket to replace it. Ten minutes later, it’s delivered by a drone（无人机）.

As you leave for work, the lights turn off by themselves. Your home goes into “sleep” mode to save energy.

Will all this come true? Perhaps the future is much closer than we think.

【推荐2】Have you ever wondered why different kinds of fruit have so many colors? According to Lu Wei from the Chinese Academy of Sciences, fruit colors actually come from their different pigments. These pigments appear in different amounts (数量), depending on the fruit’s environment. This causes the fruit to turn a certain color.

To find out how environment influences fruit colors, Chinese scientists studied more than 280 different fruit colors. They found that red fruits are likely to grow in cooler places. You can find them growing in many places around the world instead of just in one place. Blue and purple fruits mostly grow in warmer places. They grow a lot in just one specific (特定的) area. The closer the fruit is to the equato (赤道), the darker its color will be.

Animals also have an influence on the development of fruit colors. Animals eat fruit and drop the seeds (种子) in other places later. This helps the fruit spread and grow in different places. Therefore, in order to attract (吸引) animals, some fruits develop colors that are easy to see. However, animals see colors in a different way. Fruit needs to develop colors that are suited to animals’ visual (视觉的) abilities. For example, birds can see red more easily than humans can. So there tends to be more red fruit in areas where birds live.
