九年级英语单选题中等难度题查看答案及解析
To make our digestive (消化的) system work well， we should avoid doing some things after having a meal， for example， drinking water. It is true that a person should drink 8 glasses of water every day to stay healthy. However， drinking water right after eating or even during a meal may disrupt (扰乱) digestion. It might influence the natural levels of acid and bile (酸和胆汁) that are necessary for proper digestion. What’s more， drinking cold water after eating might slow down （减慢）digestion. So try to avoid drinking water at least an hour after a meal， and avoid drinking it while eating.
Though walking after eating is healthy， doing it at once after a meal is not. Doing so will make it difficult for the digestive system to take in nutrients (营养) from the food. Besides， the blood will flow towards other parts of the body， like legs， hands， etc. That will make the digestive tract(消化道) not have enough blood flow for proper digestion. So we should wait for at least 2 hours after eating， and then begin exercising.
Sleeping should also be avoided right after eating. This is because going to bed right after a meal will lead to improper digestion. What’s more， such a habit will also make you put on a lot of weight. Therefore， wait for an hour or two， and then go to sleep.
Many of us have the habit of drinking tea just after lunch or dinner， which is really unhealthy. The tea leaves are rich in acid which prevents the protein（蛋白质）in the food from digesting. The best time to drink tea is at least one hour after eating.
Eating fruits right after a meal may fill the stomach with air and we’ll feel uncomfortable. They will also take time to reach the digestive tract， disturbing the whole process of digestion. To protect your stomach from digestive problems， eat fruits before or after 1-2 hours of a meal.
In a word， if you avoid doing all the above things after eating， you will surely make your digestion easy， and you will be less likely to have digestive problems.
