You know those nutrition guidelines the government issues every few years? It turns out that following them isn't just good for your health. It's good for the planet, too.
“What we found is that impacts vary across nations, but in the highimpact nations, in general, you can see that, if you follow a nationally recommended diet, despite the fact that these diets don't mention explicitly—or most of them don't explicitly mention—environmental impacts, that you are going to have lower environmental impacts due to that. So that's sort of fairly clear across all the highincome nations.” said Paul Behrens, an environmental scientist at Leiden University in the Netherlands.
The food we eat takes a big toll on the environment. A third of the icefree land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all humancaused greenhouse gas emissions. Fertilizer runoff also leads to other problems, like the algae blooms in Lake Eerie and the Dead Zone in the Gulf of Mexico.
However, following dietary guidelines would reduce those impacts, especially in wealthy countries like the US. “Most of the reductions come from meat and dairy，” which have an outsized impact on land use and pollution, and are a major source of greenhouse gases.(That's partly due to cow farts. Seriously.) Following the suggestions would also mean eating fewer calories, since many people here eat more than they need.
Overall, in highincome countries, Behren's team estimates that following the rules could result in as much as a 17 percent reduction in land use, a 21 percent reduction in nutrient pollution, and a 25 percent drop in agricultural greenhouse gas emissions. Cutting down on how much food we waste—which is roughly a third in the US—could help even more. The results are in the Proceedings of the National Academy of Sciences.
Of course, people are notoriously bad at following diets. But: “These nationally recommended guidelines do actually have a knockon effect on other areas of policy making. So if I'm developing a new healthyeatingforschools program then that's going to be based off a lot of detail that I get from the nationally recommended guidelines. So while it might not necessarily be the case that people follow directly … they actually are quite influential on the preparation of other advice.”
It seems that a smaller environmental footprint and a healthier lifestyle could go hand in hand.
1.Which of the following statement will Paul Behrens approve of?
A. Following a nationally recommended diet can have similar impacts in different countries.
B. Following a nationally recommended diet can do good to our health.
C. Not all the countries have recommended diets in an explicit manner.
D. Some highincome nations don't mention the diet explicitly for its impacts can be ignored.
2.What do the underlined words “takes a big toll on” in paragraph 3 probably mean?
A. shows signs of B. has a bad effect on
C. takes full advantage of D. makes up for
3.Which of the following is TRUE according to the passage?
A. Food production can lead to about 20 percent of humancaused greenhouse gas with only a third of the icefree land used.
B. It is estimated that following dietary guidelines can lead to decrease in more land use than in nutrient pollution.
C. Paul Behrens' new program concerning healthy eating for schools is likely to be based on national nutrition guidelines.
D. Some wealthy countries tend to reduce meat and dairy though the other areas of policy making isn't effected much.

As bike-sharing booms in China, a guideline was released by the government to promote a new form of the sharing economy - this time involving vehicles.
Car-sharing, which provides an alternative for people to travel in cities, will be the new innovation in a service model. The released guideline focuses on legal status, insurance and regular maintenance of cars before they join sharing services. It encourages the development of car-sharing, which is expected to reduce the liking to individually buy vehicles and ease traffic congestion amid a surge in recent years of private-car ownership.
“However, there is a long way to before the purpose of the guideline comes true,” said Xia Xueluan, a professor of sociology. “First, a car costs at least 100.000 yuan, almost 500 times that for a shared bicycle. Besides, shared cars also take the same spaces as other private cars, so parking will be another problem.”
“Meanwhile, traditional car rental companies are competing with the emerging car-sharing business. It’s estimated the charges will be almost the same for both forms of cars rentals,” Xia said. “How to survive fierce competition will remain a challenge for car-sharing providers,” he added.

Christine Reynolds worked at the public library in Yosemite National Park. When the government issued shutdown orders to slow the spread of the coronavirus(冠状病毒), she loaded the back of her car with donated books and began her own mobile library.“I know this may not be conventional, and yet it has worked and I feel of use,”she said.
Across the United States，volunteers are reporting a jump in little free libraries as readers look to pass the time. Made of wood or brick，and placed in front of parks or in the trunk of a car， the libraries have seen their small spaces filled with books.
Around 1,000 people live in the Yosemite Valley，where entertainment options are limited and some residents say Christine Reynolds' mobile library and her friendly chats offer a needed break.“I live in a rural area，so the Internet is not a guarantee. The time that some people might fill with online services is not an option for me. I turn to books to fill that gap.” said Connor Timpone, who lives east of Yosemite Valley. “Books have been a bright spot for me.”
“The spaces also have transformed into a new purpose. Readers are leaving can goods and other needed items to assists fellow neighbors. The libraries allow neighbors to help one another without getting physically close,” said Greig Metzger, director of the nonprofit Little Free Library.
Since 2009，tens of thousands of little free libraries have sprung up in the United States and more than 100 countries. The small spaces operate by donation and through volunteers. Volunteers check the free libraries weekly, and the Selection is always different from the week before. Though the work Lakes much effort and time, it is rewarding.
1.What do we know about Christine's library?
A.It follows the traditional practice.
B.It is placed in the back of her car.
C.It mostly consists of her own books.
D.It is sponsored by the National Park.
2.Why is the number of little free libraries rising rapidly?
A.They meet people’s needs on special occasions.
B.They've received a great many donated books.
C.They can be easily constructed in many ways.
D.They can provide access to online services.
3.What is the new function of the little free libraries?
A.Supplying varieties of books.
B.Guaranteeing a needed break.
C.Creating a bond among neighbors.
D.Getting neighbors physically close.
4.How do the libraries operate on a daily basis?
A.With the support of the local government.
B.Through donations and voluntary services.

Three months after the government stopped issuing（发放）or renewing permits for Internet cafes because of security（安全）concerns, some cafe owners are having financial（经济的）concerns of their own.
The permits were stopped suddenly three months ago by the government until new safeguards could be put in place to prevent misuse of the information superhighway, but for cafe owners it’s a business breakdown with no fix in sight.
“I handed in a request to open up an Internet café and received the conditions,” said the businessman Obeidallah. “I rented a place in the Sharafiah district at SR45,000 and prepared the place with equipment that cost me more than SR100,000. When I went to the local government after finishing everything, I was surprised to find that they’d stopped issuing permits for Internet cafes.”
Having an Internet cafe without Internet is much like having a coffee shop without coffee. “I’m avoiding closing the place, but it’s been more than three months with the situation ongoing as it is.” Obeidallah said. “Who will bear the losses caused by the permit issue?”
The decision took many cafe owners by surprise. “I asked to open an Internet café, and I was handed a list of all the things that were needed to follow through, such as a sign for the place, filling out forms,” said Hassan Al-Harbi.
“I did all that was asked and rented a place. And after the Haj vacation I went to the local government and they surprised me, saying that there are new rules that forbid the issuing of any more Internet cafe permits and that one can’t even renew his permit. I’ve lost more than SR80,000,” Al-harbi added.
As for the government, officials say a method to deal with it is on the way. But security concerns come before profit（盈利）.
1.The government stopped issuing or renewing permits for Internet cafes ________.
A. to prevent misuse of new safeguards in Internet cafes
B. to make cafe owners earn less profit from their business
C. to stop the use of the information superhighway on Internet
D. to make sure of the proper use of the information superhighway
2.The government’s decision led to the fact that many cafe owners ________ .
A. suffered heavy financial losses B. asked to open up Internet cafes
C. continued to operate Internet cafes D. asked the government for payment
3.The underlined phrase in the last paragraph “on the way” means ________.
A. to be studied B. to be put into practice
C. to be changed D. to be improved
4.The cafe owners found the government’s decision ________.
A. surprising and unacceptable B. understandable and acceptable
