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 fanners" 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 consume red meat because of its too much fat content.Beyond that, there are environmental reasons, too. Raise 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 here 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.

Everyone has a favorite cure for a case of the hiccups. Some people think that a good scare is necessary to get well. Others eat a teaspoon of sugar. Still others drink a glass of water with a knife in it.
An American man named Jack O’Leary claimed to have hiccupped 160 million times over a period of eight years. He tried 60,000 cures, but none of them worked. Finally he prayed to Saint Jude, the saint of Hopeless cases, and his hiccupping stopped immediately.
It took a British plumber eight months to cure his hiccups. People from all over the world wrote him letters with suggestions for getting well. He tried them all, but the hiccups continued. Finally, he drank a “secret’’mixture someone had sent him. By that evening his hiccups were gone. Why did these cures work for these two men? No one really knows. But people who have studied many cases of hiccups have an idea. Hiccups usually go away if you believe in the cure.

Here’s part of what Bruce has to say about science education…
I consider science education to be critically important to both science and the world, and I shall frequently deal with this topic on this page. Let’s start with a big-picture view. Science has greatly advanced our understanding of the natural world and has enabled the creation of countless medicines and useful devices. It has also led to behaviors that have improved lives. The public appreciates these practical benefits of science, and science and scientists are generally respected, even by those who are not familiar with how science works or what exactly it has discovered.
But society may less appreciate the advantage of having everyone acquire the ways of thinking and behaving that are central to practice of successful science: scientific habits of mind. These habits include a critical attitude toward established claims and a strong desire for logic and evidence. As famous astronomer Carl Sagan put it, science is our best detector (检测器). Individuals and societies clearly need a means to logically test the constant clever attempts to operate our purchasing and political decisions. They also need to challenge what is unreasonable, including the intolerance that led to so many regional and global conflicts.
So how does this relate of science education? Might it be possible to encourage, across the world, scientific habits of mind, so as to create more rational (理性的) societies everywhere? In principle, a strong expansion of science education could provide the world with such an opportunity, but only if scientists, educators, and policy-makers redefine (重新定义) the goals of science education, beginning with college-level teaching. Rather than only conveying what science has discovered about the natural world, as is done now in most countries, we should provide first all students with the knowledge and practice of how to think like a scientist.
小题1: Which of the following is NOT included in the “scientific habits of mind”?
A.A critical attitude toward established claims. | B.A strong desire for logic. |
C.A clever and active mind. | D.A strong desire for evidence. |
A.To create more rational societies everywhere. |
B.To relate decision-making to science education. |
C.To encourage science education around the world. |
D.To set right goals of science education. |
A.Offering all students enough practice to drill their mind. |
B.Equipping all students with a thinking model of a scientist. |
C.Telling students what science has discovered about the natural world. |
D.Advising all students to challenge all established scientific achievements. |
A.Bruce Alberts, a great science educator |
B.Science education and world peace |
C.The government and science education |
D.Bruce Alberts’ opinion on science education |
Despite what it promiises,GM technology actually has not increased the production potential of any corp. In fact
Studies show that the most crown GM croo.
GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides(***虫剂). On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition.
At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.

C.fair distribution of their crops | D.using more crops for fuel |
A.Optimistic | B.Defensive | C.Disapproving | D.Casual |
