Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment. Here are some guidelines to follow:
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from. Besides so many choices, we now hear about our “food print”, the amount of land needed to supply one person’s nutritional needs for a year. Do we buy cherry tomatoes from Mexico or tomatoes grown locally in a hothouse? Do we get the Granny Smiths from the farmers’ market or the supermarket? Is organic produce healthier for us and the planet?
These are very complex issues that require analysis of many criteria, including the energy used in producing and transporting the food, as well as the type of soil and methods of raising the food.
Despite the complexities, there are some general guidelines you can follow. For instance, eat less meat or eat low on the food chain. Your doctor may have recommended you to restrict your consumption of red meat because of its too much fat content. Beyond that, there are environmental reasons, too. Raising food animals contributes substantially to climate change because a meat-based diet requires more land, energy and water than a plant-based one.

Drinking plenty of fluids is significant during hot weather or when exercising. But is bottled water the way to go? You may not think so when seeing the true costs. Based on a survey, manufacturing the 30-plus billion plastic water bottles can produce more than 2.5 million tons of carbon dioxide and use three times the amount of water in the bottle. Adding in transportation, the energy used comes to over 50 million barrels of oil equivalent (等价物). Consequently, skip the bottled water and drink tap water, both at home and at restaurants. Additionally, bottled water is not necessarily cleaner than tap.
In Paragraph 2 the author puts forward three questions mainly ______.
A. to prove Americans have less food to choose from
B. to show us the shopping habits of most Americans
C. to indicate Americans tend to buy food from abroad
D. to remind people to reconsider their food purchase
According to the text, which of the following is true?
A. Americans all prefer to buy cherry tomatoes from Mexico.
B. The plant-based diet is responsible for the climate change.
C. Americans have a variety of food to choose from.
D. Organic produce is the only choice for Americans.
Based on the last paragraph, we know that ______.
A. bottled water is cleaner than tap water
B. tap water is economical as well as eco-friendly
C. bottled water is more available than tap water
D. tap water uses one-third the cost of bottled water
What is the best subtitle for the last paragraph?
A. Skip bottled water, carry tap B. Drink bottled water
C. Produce plastic water bottles D. Save water resources

For the past many centuries, people had been enjoying the benefits of green tea for the body. Many people would prefer drinking green tea than white tea and black tea, simply because of its distinct aroma(香味) not found in other types of tea. Nowadays, keeping the natural greenish color of tea leaves remained just like before. This is done by preparing the green tea just like the way it was prepared before—by washing the leaves right after pulling off them from the bush, then boiling them.
There have been many healthful claims saying that drinking green tea-based products help a lot in improving the general health of their body. For a long time, there has been many beliefs saying that green tea can help, cure beriberi disease(脚气病), treat wounds, and even prevent tiredness. Now modern technology determines that there are even added healthful benefits that include reducing the possibility of having a heart disease and helping people to lose more weight easily.
Besides, studies have found out that green tea has Polyphenols(多酚类), a type of flaonoid(类黄酮) that greatly reduces the amount of time of cell maturation. The flavonoid found in green tea is called EGCg- a stronger matter than Vitamin C and E. It is believed to be 20 times stronger than these mentioned vitamins.
Having two cups of green tea daily is a good routine for your body. However, most doctors would suggest drinking at least 4 cups a day is the best. You can slowly increase the amount of drinking it to allow your body to get used to it. There is nothing to lose but everything to gain in drinking green tea.
