It’s a rink which has become synonymous with a healthy life style-but is green tea the magical potion many heath sites would have us believe? Green tea has been popular in China for centuries and has been used in traditional Chinese medicine to treat a number of health issues-including depression.
Its virtues have also been extolled by celebrities and so-called heath experts for a number of reasons. These include its ability to help weight-loss as well as containing antioxidants which are believed to help combat different types of cancer. heart disease and Alzheimer's. Given these claims, it’s easy to see green tea as sort of magical elixir.
1.Green tea and weight loss
Green tea contains B vitamins, folate (naturally occurring folic acid), manganese, potassium, magnesium, caffeine and other antioxidants, such as catechins. It’s catechins along with green tea’s naturally occurring caffeine which are thought to help the body burn more calories. Weight-loss products containing green tea have a higher concentration of catechins and caffeine than the typical green tea beverage. However, there's some bad news. A review from 2012 of 18 studies involving 1,945 people found no significant effect of weight loss from drinking green tea.
2. Green tea and cholesterol
Thanks again to the catechins, in a reputable review from 2013 of 11 studies involving 821 people, it was found daily consumption of green and black tea (as a drink or a capsule) could help lower cholesterol and blood pressure.
It's important to note, however, that the authors of the study pointed out the trials were short-term, and cautioned longer-term trials would be needed to substantiate their findings. These were back up by an earlier review in 2011, which found drinking green tea enriched with catechins led to a small-reduction in cholesterol, a main cause of heart disease and stroke.
Though no one could say for certain how much green tea a person would need to drink to reap the benefits.
3. Green tea and cancer
On this the NHS is clear. There is no evidence drinking green tea protects against different types of cancer.
1.What's the meaning of the underlined word in the second paragraph?
A. Criticized B. Commented C. Praised D. Exaggerated(夸张)
2.People think the ingredients in green tea that can burn more calories are_______.
①vitamins ② folate ③catechins④magnesium ⑤ caffeine
A. ①② B. ④⑤ C. ③⑤ D. ②⑤
3.According to Part 2, we can infer that______
A. further researches are needed to prove the findings
B. the short-term research is not right
C. the long-term research is not in the works
D. over drinking green tea benefits health

Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet’s health, and people’s health may be suffering from it.
The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes more clean, sometimes not.”
It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content (含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn’t have fluoride (氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that’s behind the recent rise in bad teeth.
Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals (化学物质) into the water.
According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.
In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.
So, if you are worried about the effect of bottled water on the Earth, you can take the following steps.
● Drink from your tap. Unless your government warns against this, it should be fine.
● Get a container (容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.
● Keep it cool. Don’t drink from a bottle that has been sitting in the sun, don’t store it near chemicals, and don’t reuse plastic bottles.
● Choose glass containers over plastic if possible. When finished, recycle!
1.What is the main idea of the article?
A. Drinking tap water is the only choice for people.
B. Glass containers are better than plastic bottles.
C. Plastic bottles are harmful to the environment.
D. Bottled water may not be as good as we think.
2.What can we learn about plastic bottles from the article?
A. They break down in less than 300 years. B. They can be used for many other things.
C. They are a risk to the environment. D. They are cheap to make.
3.According to the article, we can know that bottled water is __________.
A. no problem for the environment B. more expensive than tap water
C. always safer than tap water D. better for babies
4.Which of the following about tap water is NOT mentioned in the article?
A. There are a lot of problems storing tap water.
B. Bottled water can be just tap water in a bottle.
C. It may be better for your teeth.
D. It may contain fluoride.
