For years experts have argued that poor households are consuming less nourishing food than the rest of the population.

But a survey of some of the lowest earners in Britain shows the nutritional value of what they eat is little different to everyone else.

In fact, the same deficiencies in diet were shared by all the population and the findings suggest that poor eating choices are far more widespread than previously suspected - affecting many wealthier families.

These included low fruit and vegetable consumption, not eating enough oily fish and eating too much saturated fat and sugar.

“This is a large and significant study and it shows we are all eating just as bad a diet as each other,” said Tim Lang, professor of food policy at City University.

The poorest families were eating only slightly more sugar and slightly less fruit and vegetables, according to the study of 3,728 respondents in the bottom of the population.

Alison Tedstone, head of nutritional science at the Food Standard Agency, said: “ Overall, people on low incomes have less than ideal diets, but their diets are only slightly worse than those of the rest of the population.”

The study also showed that low earners are choosing to eat unhealthily. Their food choices were not linked to their income, their access to shops or their cooking skills.

The findings appear to contradict assumptions that the poor cannot afford healthier foods or are too far away from shops that sell them.

The Low Income Nutrition and Diet Survey showed that like the rest of the population, the poor's daily fruit and vegetable intake on average is below the recommended five portions. Fewer than 10 per cent of respondents hit this target, while around 20 per cent ate less than a portion per day.

More than three quarters (76 per cent) of men and 81 per cent of women did less than one 30-minute session of moderate or vigorous exercise per week.

Some 45 per cent of men and 40 per cent of women were smokers.

This compares with 28 per cent of men and 24 per cent of women in the general population.

1. According to the passage, which of the following is true?

A. Whether the poor or the rich maybe have a bad diet.

B. Even the poor can enjoy enough fruit and fish consumption.

C. Only the poor have a bad diet.

D. The study was conveyed in both the rich and the poor.

2.What kind of persons maybe eat most sugar?

A. The rich.                  B. Men.                                C. The poorest.                  D. Women

3. From the passage, we can learn __________.

A. the poor choose unhealthy food because of low income

B. having no access to shops also leads to the poor’s bad diet

C. the poor’s daily fruit intake is as much as general people

D. the number of smokers in the poor is bigger than that in general people

4. What’s the best title of the passage?

A. The poor’s healthy problem.                            B. Keep off junk food.

C. How to have a good diet.                                  D. A diet survey.

Sleep to Lose Weight

A recent study found that people who sleep less tend to be fat. Experts said it's time to find out if more sleep can fight obesity.

Nowadays, the most popular method to keep fit is doing more exercise and eating less. Some people even take weight-loss drugs to keep slim, which is unhealthy and harmful to your body. " 1.As a result, we’ve failed to recognize the value of good sleep," said a physician.

Men sleep an average of 27 minutes less than women, and overweight and fat patients sleep less than patients with normal weights. In general, fat people just sleep about 1.8 hours less a week than those with normal weights.2.Only an extra 20 minutes of sleep per night contributes to a lower BODY MASS INDEX （身体质量指数）.

We caution that this study does not establish a cause-and-effect relationship between limited sleep and fatness.3.Therefore, let's stay thin by sleeping more!

Here are some other advantages of sleeping more.

• You'll learn better.

This isn't just for children. Adults who get enough sleep also do better on tests of short-term memory.

A study published Monday found that people who sleep less tend to be fat，and experts said it’s time to find out if more sleep will fight fatness.

“We’ve put so much emphasis on diet and exercise that we’ve failed to recognize the value of good sleep，”said Fred Turek，a physician at Northwestern University.

Monday’s study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index－a measure of weight based on height increased.

“Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights，”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.

“Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients，”the study said.

“Our findings suggest that major extensions of sleep time may not be necessary，as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index，”it added.

“We caution that this study does not set up a cause­and­effect relationship between restricted sleep and fatness，but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”

The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

Inan interview，Turek said some studies have shown the lack of sleep causes declines in an appetiteholding back protein hormone，and increases in another hormone that cause a longing for food.“In addition neuropathies(神经疗法)in the brain governing sleep and fatness appear to overlap(部分重叠)，”he said.

“Fatness has been rising dramatically in developed countries and reached epidemic(流行病)levels in the United States，”it added，“leading to a variety of health problems.”

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.

Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of others, for example, fresh water. It is reported that we will have no coal or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.

In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.

1.Which is not mentioned in this passage?

A. Fresh water.　　 B. Forest.　　　　　 C. Oil.　　　　　　 D. Coal.

2.What may happen in 100 years?

A. We may still have enough oil.

B. We may still have enough coal.

C. We may have a little oil.

D. We may have no coal or oil to use.

3.Which of the following is right?

A. Waste brings problems.

B. Waste can bring no problem.

C. China is rich in fresh water.

D. Students never waste things.

4.Which is the best title of this passage?

International experts meeting in Australia say global carbon emissions (排放) can be reduced by more than 50 percent through simple energy saving measures. People at a conference in Australia, which increasingly relies on coal for power, say that reducing power consumption is an affordable way to both cut energy costs and reduce pollution.

While many nations turn to cheap and dirty energy sources, such as coal, to meet their increasing energy needs, analysts in Australia say the best way to meet those needs is to improve energy efficiency.

A range of simple solutions include using energy-efficient homes, household appliances and lighting, and driving electric cars. Encouraging homeowners and office workers to switch off their televisions and computers at the end of the day is also seen as an effective way to save electricity.

Grayson Heffner, from the Paris-based International Energy Agency, says reducing consumption could greatly cut global carbon emissions. He calls efficiency strategies (策略) the “soft giant” of clean energy.

“We forecast that energy efficiency will deliver something like three-quarters of the greenhouse gas emissions reductions over the next 20 years. So in the short term energy efficiency is the main way that we reduce greenhouse gas emissions but oftentimes it is not so importantly stressed in the discussions,” said Heffner.

Energy experts working in China say the government is making significant cuts in power usage.

Wan Xingwang, a Beijing-based representative of the Energy Foundation, a U.S. non-government organization, says the results have been impressive.

“In the past five years China achieved about 19.1 percent of energy reduction of its GDP. That translates to something like more than 600 million tons of coal savings,” said Wan Xingwang.

While most nations have some sort of government-sponsored energy efficiency programs, energy analysts say initiatives (主动性) by individuals and companies can also help cut demand.

Steven Nadel, executive director of the American Council for an Energy Efficient Economy, a non-profit group based in Washington, says other developing nations are recognizing the benefits of cutting power consumption and taking action.

1.To increase their energy supplies, many nations _____________________.

A．turn to new energy                      B．turn to cheap energy

C．develop solar energy                    D．introduce clean energy

2.Which of the following cannot help to reduce energy consumption effectively?

A．Using electronic products in small size.

B．Using more electric cars.

C．Turning off computers after work.

D．Building energy-efficient houses.

3.What can we learn from what Grayson Heffner said?

A．75% of the greenhouse gas emissions can easily be cut in the next 20 years.

B．Ways to reduce greenhouse gas emissions should be discussed.

C．Using clean energy is the strategy to cut global carbon emissions.

D．The key to reducing greenhouse gases in the short term is to improve energy efficiency.

4.According to the last two paragraphs, which of the following statements is true?

A．The programs reducing energy consumption shouldn’t be sponsored by individuals and companies.

B．All nations have government-sponsored energy efficiency programs.

C．It is time that all nations should combine their efforts to save energy.

D．Some developing nations are taking action to cut power consumption.

Many people believe eating healthily is expensive and more costly than buying junk foods. But our new research, published in the BMC Pubic Health ,shows this isn’t the truth.

Less than 7% of Australians eat healthily. Most of the Australian family food budget is being spent on junk foods and drinks that are high in fat, sugar and salt. As a result, two-thirds of adults （63%）and one-quarter of children are overweight.

We used the Australian Health Survey 2016-2017 and the suggestions of the Australian Dietary Guidelines to model healthy diets for a family of two adults and two children every two weeks. We collected food prices in supermarkets and stores in high and low-socioeconomic（社会经济地位低的）areas in Brisbane, and compared the diet prices with family incomes.

In both areas, a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets. About 58% of the food budget for present diets is spent on junk foods, including takeaway foods（14%）, and sugary drinks（4%）. In the low-socioeconomic area, a family of two adults and two children spend $640.20 every two weeks on their present diets, but could buy a healthy diet for $5560.93 every two weeks. In the high socioeconomic area, these numbers are S661.92 and $580.01.

Present diets cost more than healthy diets, so it is surely not the price that helps to drive preferences for unhealthy choices.

1.What did the researchers find?

A.Most Australians eat unhealthily.

B.Half Australians live on junk foods.

C.Most Australian kids have fat problems.

D.Australians have a preference for sweet foods.

2.How did the researchers get the result?

A.By doing the study online. B.By making a comparison.

C.By carrying out interviews. D.By asking personal questions.

3.What can we learn from Paragraph 4?

A.A healthy diet is actually cheaper.

B.Australian foods are becoming healthier.

C.People choose junk foods for their low prices.

D.Healthy foods are becoming more expensive.

4.What might the following paragraph be about?

A.The harm of junk foods. B.How we can eat healthily.

C.Why people choose junk foods. D.The advantages of a healthy diet.
