【推荐1】Experts have long debated the best diet for health. They believe that it's not just what we eat that's important for good health but when we eat. When our diet pattern matches the biological clock well, our body can work at its best. Breaking the rule—by eating late meals or having night snacks—could lead to weight gain and metabolic (新陈代谢) trouble.

Many people, however, eat from roughly the time when they wake up until shortly before they go to bed. Studies show that the average person starts with something like milk and coffee shortly after rising and ends with a glass of wine, a late-night meal or a handful of chips, nuts or some other snacks shortly before bed. That pattern of eating is against our biological rule.

Scientists have long known that the human body has a master clock in the brain, which controls our sleep-wake cycles in response to bright light exposure (暴露). A couple of decades ago, researchers discovered that there is not just one clock in the body but a collection of them. Every organ has a clock that controls its daily cycle of activities. Studies show that in every organ, thousands of genes (基因) are turned on and turned off at roughly the same time every day.

We've lived on this planet for thousands of years, and while many things have changed, there has always been one unchanged: Every single day the sun rises and at night it falls. We're designed to have 24-hour patterns in our body. These patterns exist because, just like our brains need to go to sleep each night to repair and reset themselves, every organ needs to have time to repair and reset itself as well.

【推荐2】Not long ago, people could only buy organic（有机的）food in small local shops. Today it is common in most major supermarkets. The reason for the increase is that more and more people are demanding food grown without chemicals. Since the 1990s, organic farm production has gone up to 20 percent every year. This pattern is expected to continue around the globe.

Australia leads the world in land used for organic agriculture. It has four times as much land devoted to organic farming as all of Asia. However, most of the land is not very fertile（肥沃）, and it only produces a modest amount of food. Argentina is a distant second, followed by Brazil, the United States and China. In Africa, only a very small amount of land is registered for organic farming. That does not mean Africa relies on chemicals. In fact, many farmers do not use chemicals because they cannot afford them. Yet there are no programs for these farmers to prove they do not use chemicals. Without these programs their food can never be approved organic.

India has had the most dramatic recent increase in organic farming. Like many other countries, India sees continual growth in organic food sales around the world. This, of course, leads to growth in profits. Sales of organic food were more than doubled from 2000 to 2005. Like India, many countries are trying to increase commercial organic farming to get a share of the sales. This has led to criticism. Some people believe that organic farming should not just be about making money. They think the goal is to help the environment. Others say organic farming will not continue if it is not profitable. They say that people should be able to make money while providing food that is healthy to mankind.

1. What is the text mainly about?

A．That organic food has become much more common.

B．That farming organically is growing around the world.

C．That people do not want to eat food with chemicals in it.

D．That countries all want to make money by farming organically.

2. The underlined word "dramatic" is the closest in meaning to " ________".

A．gradual	B．huge
C．continuous	D．slight

3. Why do people want to increase organic farming?

A．Organic food is good for the Earth and human beings.

B．There are fewer chemicals available for farming.

C．More and more people demand chemicals to grow food.

D．Profits from organic farming help make approved programs.

4. Which of the following is TRUE according to the text?

A．The African farmers are too poor to use chemicals.

B．Most of the African farmers don't dare to use chemicals.

C．The African farmers don't want to prove they don't use chemicals.

D．The African farmers use a very small amount of land to grow organic food.

【推荐3】Traditionally, patients who want to improve their heart health have received four main suggestions from their doctors: Eat a healthy diet, get more exercise, quit smoking, and enjoy proper amounts of alcohol. Plenty of research backs up these four pieces of advice: Large studies have found that making improvements in these four areas lowers the chance of dying of heart disease by 67 percent.

But lately, researchers are starting to recognize that there should be five recommendations on that list, not just four. They’re discovering that getting enough sleep is a powerful health protector as well. When researchers include enough sleep in their studies as a fifth cardio-preventive behavior change, they find that it lowers the chance of dying of heart disease even more: Adding a good seven hours of sleep a night in addition to making positive changes in diet, exercise, smoking, and alcohol intake lowers the chance of dying of heart disease by 83 percent.

When that news started coming out, doctors began adding sleep onto their list of recommended health behavior changes. But as an expert in heart disease, I don’t think sleep belongs at the bottom of the list. I think it should be at the top. I believe that getting enough sleep – at least seven to eight hours per night for most people –is the most important health behavior change you can make to improve the health of your heart and your overall health.

Sure, I’d prefer that everyone make all of the big five lifestyle changes, but if I could only choose one, I’d pick sleep because when you are well-rested, you have more power to make the right choices about what you eat and drink, and you have more energy to exercise and kick bad habits such as smoking and overeating. But when you’re exhausted, everything in life is more difficult.

1. What does plenty of research show about the 4 common suggestions?

A．They should be reconsidered.

B．They are the best ways found so far.

C．They are not as helpful as expected.

D．They help improve people’s health.

2. What does the latest research show?

A．Various factors lead to good heart health.

B．Enough sleep contributes to good heart health.

C．Seven hours’ sleep is most important to the heart.

D．The chance of dying of heart disease has dropped.

3. How did the doctors react to the news on sleep?

A．They just ignored it.

B．They discussed it publicly.

C．They thought it made sense.

D．They totally changed their mind.

4. What does the last paragraph mainly talk about?

A．What the importance of a healthy lifestyle is.

B．Why different factors need to work together.

C．What prevents people from living healthily.

D．Why the author makes sleep his No. 1 suggestion.

【推荐3】Every weekday, shortly after 11 a.m., a line forms at the Broadway and 38th Street location of Sweetgreen, the eco-conscious salad chain. By noon, the line has usually tripled （三倍）in size.

The scene is similar at the Chop't, or the Dig Inn, or the Just Salad one block south. Greens, once so unattractive that parents all over the country had to beg their children to eat them, have never been hotter.

At Sweetgreen , the appeal is partly ethical . The ingredients are sustainably farmed, sourced from trusted partner and served with transparency. There are vegetarian, gluten-free and “warm bowl” options. There are raw beets and organic carrots. It's enough to make the most wasteful among us feel satisfied . It is any wonder that Sweetgreen is the fastest growing salad chain in the United States?

The moral overtones extend even to the trash. As customers pay and head back toward their various workplaces , they pass an often Overflowing garbage bin with a proud sign above it that says that all of the company’s utensils, napkins, bowls and cups are plant-based, "which means     they go in the compost bin（堆肥箱），along with any leftover food." "Nothing from inside Sweetgreen goes to the landfill（垃圾填埋）,” the sign declares further, virtuously.

But that's far from the truth, although it,s not the chain's fault.

Zara Watson, a lawyer who eats at Sweetgreen three times a week, throws the waste from her healthful lunch directly in the trash because she does not have to compost at her office. So does Sam Hockley, the managing director at the software company Meltwater, who is willing to eat a Sweetgreen bowl for breakfast, lunch or dinner.

Salad is appealing not only because the food is healthy for us but because it's healthy for the world. But even as Sweetgreen and its marvelous effort, the compostable（可降解的） containers the chain puts such care into providing are, more often than not, going to a landfill.

Eric Goldstein, the New York City environment director, said that it typically takes a city about a decade to transition to successful composting. Now New York faces several challenges, one " which is educating people on how to compost in the first place. u!f you were to stop a person in the street, 1 don't know how many people could even tell you what composting really is," he said. "We need a large-scale program to let New Yorkers know why this is important and how to participate in the program .”

And of course, composting itself is not the gold standard of eco-conscious lunch disposal, “it's still best to use reusable things, even before composting and recycling,” Mr. Goldstein said. "But composting is an extremely valuable thing to do."

A．Because composting is unnecessary where she works.

B．Because she thinks it is wrong to compost waste.

C．Because the material Sweetgreen uses isn't compostable.

B．Most Americans have realized the necessity of garbage classification.

C．The transition to successful composting in New York is a tough task.

D．The best way to deal with leftover food is to turn it into compost.

【推荐3】Surfing for hours on the Internet consumes a lot of electricity and is harmful to the environment. However, a new ecological PC saves energy as it operates：it produces about 70 percent less CO₂than conventional computers.
As a work tool, a leisure activity resource, and a personal assistant, computers seem to be everywhere. Yet the environmental performance for today's computers leaves a lot to be improved: they rapidly become out of date, and typically contain poisonous materials and individual parts that are difficult to recycle. Moreover, they consume plenty of power whose production, in return, causes the release of CO₂into the atmosphere.
Employees at the MicroPro Company in Ireland, teaming with colleagues at the Fraunhofer Institute for Reliability and Microintegration IZM in Berlin, have engineered a wooden—frame computer with reduced environment impact. As the first computer for its class, the“iameco”(pronounced I-am-eco) was awarded the “EU Ecolabel”, the European Union’s environmental label. “This touch-screen PC has very low energy consumption over the entire lifecycle” explains Alexander Schlosser, scientist at IZM.
Over the full product life cycle, it releases 70 percent less CO₂ than a typical desktop PC with monitor. In addition, it can be easily recycled. Of the materials used, 98 percent can be recycled. Indeed, 20 percent of the computer can be reused immediately—in other words, many parts can be reused for repairing other computers—such as parts of the wooden frame.
1. Paragraph 2 mainly talks about______________.
